    Full Text Available Penelitian tentang pengelolaan limbah domestik berbasis komunitas Di kawasan Daerah Aliran Sungai (DAS Tawing ini didasarkan pada fenomena bencana banjir yang terjadi hampir setiap tahun. Faktor penyebabnya tidak hanya karena faktor alam namun juga disebabkan adanya penurunan daya resap dan pendangkalan sungai di berbagai daerah. Hal ini terkait juga dengan kebiasaan, kesadaran, sikap dan perilaku masyarakat terhadap lingkungan yang masih rendah. Sebagian masyarakat di kawasan daerah aliran sungai Tawing masih membuang limbah domestiknya, baik kotoran maupun sampah rumah tangga ke sungai. Hal ini lebih disebabkan persepsi yang berkembang dalam masyarakat bahwa sungai berfungsi sebagai halaman belakang (backyard sehingga sungai digunakan sebagai tempat pembuangan limbah. Di sisi lain keberadaan komunitas pemuda pecinta lingkungan di daerah di Kabupaten Trenggalek berdampak positif jika peran dan kapasitas komunitas tersebut dikembangkan terutama terkait dengan upaya pemberdayaan masyarakat dalam mengelola limbah domestiknya. Hasil penelitian menunjukkan bahwa pengelolaan limbah domestik yang dilakukan adalah aplikasi 3R (Reuse, Reduce dan Recycle dengan kelompok sasaran: komunitas Ibu rumah tangga, Komunitas Petani, komunitas Guru dan pendamping dan Komunitas pemuda karang taruna. Strategi yang dikembangkan dalam pengelolaan limbah domestik meliputi: Perencanaan dan Program Pengembangan, Penguatan kelembagaan dan Pengembangan jaringan dan kerjasama. Hingga saat ini pengolahan limbah domestik menjadi pupuk organik, larangan meracuni sungai Tawing dan pemberian sanksi kepada masyarakat yang membuang sampah merupakan program yang sudah berjalan, namun dipandang perlu untuk dikembangkan dengan sasaran wilayah yang lebih luas. Sosialisasi secara intens dan pendampingan kepada kelompok sasaran perlu terus dilakukan agar terjadi keberlanjutan program.

    Full Text Available ABSTRAK Berbagai macam pelayanan perawatan kesehatan yang disediakan oleh rumah sakit akan berpotensi menghasilkan limbah medis. Walaupun sebagian besar limbah rumah sakit dapat dikelompokkan sebagai limbah yang tidak berbahaya yang memiliki sifat yang sama dengan sampah rumah tangga dan dapat dibuang ke tempat penimbunan sampah, sebagian kecil dari limbah medis harus dikelola dengan tepat untuk meminimasi resiko terhadap kesehatan masyarakat. Model pengelolaan limbah medis yang dikembangkan ditujukan untuk meminimasi resiko terhadap fasilitas umum dan komersial seperti fasilitas ibadah, bank, perkantoran, restoran, hotel, stasiun pengisian bahan bakar, fasilitas pendidikan, mall dan pusat perbelanjaan, taman dan pusat olahraga/kebugaran, akibat pengangkutan limbah medis dan abu hasil pengolahannya. Tingkat resiko dari setiap fasilitas di atas ditentukan menggunakan metode Analytical Hierarchy Process (AHP. Permasalahan diselesaikan dengan mengaplikasikan linear programming menggunakan software optimimasi LINGO®. Output model berupa optimasi alokasi limbah medis dari setiap rumah sakit ke fasilitas pengolahan dan alokasi abu dari fasilitas pengolahan ke tempat penimbunan akhir. Hasil model memperlihatkan bahwa rute terpendek tidak menghasilkan total resiko terkecil karena dipengaruhi oleh jumlah dan tingkat resiko dari setiap fasilitas yang dilalui oleh kemdaraan pengangkut limbah medis dan abu. Perbedaan fasilitas yang berada di sekitar pengolahan limbah medis juga akan menghasilkan total resiko yang berbeda. ABSTRACT A broad range of healthcare services provided by hospital may generate medical waste. Although a large percentage of hospital waste is classified as general waste, which has similar nature as that of municipal solid waste and, therefore, could be disposed in municipal landfill, a small portion of medical waste has to be managed in a proper manner to minimize risk to public health.

    Full Text Available Sand filter is frequentlyused to treat contaminated water. Channel filter system is a modification of sand filter where the channel is shaped thus the land requirement could be minimized, water is flowed horizontallyfrom intial tank to finaltank through sand filter. Employing the channel filter to treat domestic wastewateris capable of reducing E. Coli up to 98.14%, increasing DO up to 27% and decreasing BOD5 up to 27%. Unfortunately, the final content of E.Coli after treatment process completed is still unacceptable for drinking water. Several options are available to improve the performance of the channel filter system. One of the promising alternativesis modifying the filter medium. Zeolite is natural material that has been utilized to improvewater quality based on several parameters such as Fe, Mn, organic materials, CO and others. Application of zeolite to diminish E. Coli is a challenge. This paper will investigate the effectiveness of zeolite to lower E. Coli contained in domestic wastewater . Zeolite was added to sand filter where thefraction of zeolite is about 5%. Two kind of zeolite-sand combination was implemented that is arranged and mixed zeolite-sand. Wastewater containing E.Coli was then put in the initial tank. Through the hole createdin the tank, wastewater then flowed passing through the combined zeolite-sand filter and accumulated in the final tank. Both E. Coli from initial and final tank was measured to compute treatment efficiency. The result showsE. Coli decreases up to99.99%, BOD5and DO decrease more than 71% and 66% respectively. It can be concluded that 5% addition ofzeolite is able to improve treatment efficiency ofsand filter.

    Full Text Available Abstrak Disain katup limbah yang baik dan penyetelan panjang langkah (stroke yang tepat merupakan faktor penting untuk operasi pompa hydram yang halus dan efisien. Katup limbah harus mampu menutup dengan cepat untuk menghasilkan tekanan tinggi pada saat terjadi water hammer. Disain detail katup limbah meliputi luas lubang katup limbah, luas penampang piringan katup, dan panjang langkah katup. Penelitian sebelumnya menyarankan bahwa diameter lubang katup limbah harus sama atau lebih besar dengan diameter pipa penggerak untuk menghindari terhambatnya aliran air keluar katup limbah. Namun diameter optimal katup limbah belum diketahui. Katup limbah tertutup akibat gaya drag yang terjadi karena aliran air melewati katup tersebut. Jadi geometri katup limbah adalah sedemikian rupa sehingga gaya seret tersebut meningkat dengan cepat sesuai arah pergerakan katup tersebut menuju posisi tertutupnya. Friction drag mengakibatkan kehilangan energi atau head losses aliran air melewati katup limbah yang merupakan besarnya perubahan energi aliran sebelum dan sesudah katup limbah tersebut. Head losses tersebut dapat diinvestigasi dengan mengukur tekanan di bawah katup limbah dan debit aliran yang mengalir melewati katup limbah tersebut pada posisi kesetimbangannya. Hasil penelitian menunjukkan bahwa rasio diameter lubang katup limbah terhadap diameter pipa penggerak yang mengakibatkan head losses terendah adalah sekitar 130 persen atau pada rasio luas penampangnya sekitar 172 persen. Kata kunci: Pompa hydram, katup limbah, head losses, rasio diameter Abstract Suitable design and appropriate stroke adjustment of a waste valve are important factors for smooth and efficient hydram pump operation. The waste valve must be able to close quickly to produce high pressure during a water hammer take placed. In addition, detailed design of the waste valve comprises of the hole-diameter of the valve, the cross-sectional area of valve disc, and the valve step stroke. Prior

    Full Text Available Limbah amonia dari budidaya ikan yang dibuang langsung ke perairan sekitarnya merupakan sumber pencemaran yang perlu mendapat perhatian. Potensi pasokan amonia ke dalam air budidaya ikan adalah sebesar 75% dari kadar nitrogen dalam pakan. Pengubahan nitrogen dalam sistem akuakultur yang berperan dalam pengurangan kandungan amonia terdiri atas tiga proses yakni proses fotoautotrofik oleh alga, proses bakterial autotrofik yang mengubah amonia menjadi nitrat, dan proses bakterial heterotrofik yang mengubah amonia langsung menjadi biomassa mikroba. Proses mikrobial seperti tersebut dapat dimanfaatkan untuk meningkatkan kualitas air dan mengurangi beban cemaran limbah budidaya ikan ke perairan sekitarnya. Pada prinsipnya kandungan amonia di dalam air kolam dirangsang untuk berubah menjadi alga atau bakteri. Penelitian penerapan sistem heterotrofik untuk mengurangi beban limbah budidaya ikan lele (Clarias gariepinus telah dilaksanakan di Loka Riset Pemuliaan dan Teknologi Budidaya Perikanan Air Tawar, Sukamandi. Air pemeliharaan ikan lele dialirkan ke ruang pemeliharaan ikan nila. Pemberian pakan hanya diberikan kepada ikan lele. Kandungan amonia yang ada dipacu untuk diubah menjadi biomassa bakteri dengan memberikan pasokan karbon berupa molases yang merupakan hasil samping pabrik gula.

    Full Text Available Sistem pengelolaan sampah di tempat pembuangan sampah menjadi masalah lingkungan yang besar seiring dengan pertumbuhan industri pulp dan kertas di Indonesia. Konversi limbah padat menjadi bahan bakar pelengkap untuk industri kertas juga tidak memberikan hasil yang signifikan untuk memecahkan masalah pencemaran udara pada saat karbon aktif dibebaskan dari proses pembakaran. Masalah ini secara khusus menuntut sistem pengelolaan sampah yang maju dan efektif secara terus-menerus. Baru-baru ini, optimasi pemanfaatan serat-limbah menjadi alternatif khusus untuk mengurangi tumpukan sampah di tempat pembuangan sampah. Namun, tidak semua dapat didaur ulang. Karakteristik limbah padat berserat dari industri kertas tisu cenderung menurun gramaturnya, sehingga sangat disayangkan pemanfaatannya akan berkurang bahkan setelah proses daur ulang. Di sisi lain, struktur kimianya yang telah rusak selama proses produksi tampaknya menjadi semangat baru bagi industri tekstil di masa depan dalam mengembangkan teknologi daur ulang limbah padat berserat, yang menghasilkan benang tekstil generasi baru. Fokus dalam penelitian ini ditekankan pada penemuan tas yang terbuat dari bahan serat-limbah menggunakan metode eksperimental. Identifikasi karakteristik serat-sampah berbasis padat dikembangkan melalui teknik eksplorasi multi-ply yarns berdasarkan sistem interlace. Hubungan antara penciptaan produk dan forecasting  tren pada tahun 2013 akan menjadi analisis berikutnya sebagai salah satu cara untuk memecahkan masalah sampah.Kata Kunci: limbah; multi-ply yarns; sistem interlacing.The Potential of Solid Waste as Multiply Yarn Based on Interlacing SystemsSolid-waste disposal in landfills is becoming a massive environmental problem as a result of the growth of the pulp and paper industry in Indonesia.

    Water pollution in the big cities in Indonesia, especially in DKI Jakarta has shown serious problems. One of the potential sources of water pollution is domestic wastewater that is wastewater from kitchens, laundry, bathing and toilets. These problems have become more serious since the spreads of sewerage systems are still low, so that domestic, institutional and commercial wastewater cause severe water pollution in many rivers or shallow ground water. Bases on the fact that the progress of development of sewerage system is still low, it is important to develop low cost technology for individual house hold or semi communal wastewater treatment such as using anaerobic and aerobic submerged biofilter. This paper describes alternative technology for treatment of household wastewater or organic wastewater using anaerobic and aerobic submerged biofilter. Using this technology can decrease BOD, COD and Suspended Solids (SS) concentration more than 90 %. (author)

    Full Text Available Banjir dan kekeringan merupakan sebuah fenomena yang rutin dihadapi di berbagai daerah dengan kerugian yang tidak kecil contohnya di wilayah Jabodetabek pada bulan februari tahun 2007, banjir yang terjadi selama 5 hari mencapai kerugian sekitar 8,6 triliyun rupiah. Saat terjadi banjir pengungsi sangat sulit untuk mendapat air bersih maupun air minum, di karenakan sumur penduduk yang dipenuhi lumpur dan kotoran. Kesulitan dalam memperoleh air bersih maupun air minum pada saat maupun paska bencana banjir, berdampak pada timbulnya berbagai penyakit terkait air bersih yaitu seperti muntaber, diare dan gatal-gatal. Oleh karena itu diperlukan solusi atau penanggulangan masalah air bersih dan air siap minum baik saat maupun paska bencana banjir. Menurut buku Introduction to International Disaster Management (2007, disebutkan bahwa ada beberapa alternatif dalam penyediaan air bersih dan air siap minum pada saat kondisi banjir yaitu  penyediaan air melalui tangki truk, atau dari tangki yang di datangkan  dari luar daerah banjir, melakukan proses pengolahan air banjir itu sendiri untuk menghasilkan air bersih sebagai contoh menggunakan filter. Solusi dalam hal masalah ini adalah pengolahan air minum yang berbasis mobile water treatment. Dalam kaitan tentang masalah ini perlu adanya perencanaan tentang desain instalasi pengolahan air minum secara mobile untuk kondisi darurat bencana banjir. Dalam hal ini rencana desain atau DED (Detail Engineering Design yang akan digunakan adalah mobile water treatment membran mikrofiltrasi, keuntungan dari menggunakan membran ini adalah dapat menyisihkan bakteri patogenik dan beberapa jenis virus. Pada perencanaan ini direncanakan unit-unit sebelum dan sesudah membran mikrofiltrasi agar kualitas air hasil pengolahan (effluent memenuhi baku mutu air siap minum yang sesuai dengan PERMENKES RI No.492/MEN.KES/PER/IV/2010.

    Full Text Available Kayu merupakan hasil hutan sebagai bahan dasar dari produk jadi seperti lemari, kursi, dan produk olahan lain. Pada industri pengolahan kayu, metode penentuan harga umumnya didasarkan terhadap perhitungan isi kayu (volume dimana nilai tersebut diawali dengan perhitungan diameter terkecil. Pekerja lapangan pada usaha kayu menggunakan nilai dari diameter terkecil untuk dijadikan acuan perhitungan dengan penggaris. Akan tetapi pengukuran ini kurang akurat karena kayu gelondong mempunyai bentuk yang tidak bulat sempurna. Padahal, selisih satu centimeter saja dapat menentukan grade kayu dan berpengaruh terhadap harga kayu gelondong tersebut. Penelitian menggunakan algorithma pengolahan citra telah dilakukan  maupun dengan spesifikasi tentang permukaan kayu. Teknologi yang dirancang memanfaatkan penginderaan mesin visual yang dilakukan oleh kamera  untuk melakukan penghitungan otomatis terhadap nilai kayu dengan program OpenCV. Pada tugas akhir ini, sebuah alat tepat guna dengan raspberry pi yang akan menjadi standarisasi pengukuran pada usaha kayu dengan menggunakan pengolahan citra digital. Devais yang dibuat sangat portabel dan berhasil mengukur diameter terkecil kayu dengan akurasi pengukuran 97% menggunakan metode kontur dan bounding box. Metode tersebut lebih baik dari metode lingkaran Hough dengan akurasi 89%. Perbaikan sistem dapat dilakukan pada deteksi obyek melalui pencahayaan dan segmentasi kontur.

    Full Text Available Air conditioner (AC merupakan suatu perangkat yang paling banyak digunakan sebagai pendingin ruangan. Walaupun AC saat ini sudah menggunakan teknologi hemat energi, namun apabila tidak digunakan dengan baik maka penggunaan AC hanya menjadi suatu pemborosan listrik saja. Untuk mengurangi pemborosan listrik pada AC, maka pengaturan suhu harus disesuaikan dengan kondisi ruangan. Beberapa faktor yang mempengaruhi kondisi ruangan antara lain adalah jumlah orang serta tingkat aktivitas dalam ruangan. Sebagai upaya penghematan konsumsi listrik pada AC, maka dalam penelitian ini dilakukan rancang bangun suatu sistem identifikasi jumlah orang dan tingkat aktivitas. Pada sistem ini digunakan kamera USB sebagai perangkat pengambil citra. Pada pengolahan citra menggunakan metode Histogram of Oriented Gradient (HOG sebagai penghitung jumlah orang, sedangkan metode background subtraction digunakan sebagai penghitung tingkat aktivitas.

Meskipun telah menyediakan lapangan kerja untuk masyarakat lokal, kegiatan tersebut menurunkan kualitas lingkungan, khususnya sungai, karena penggunaan merkuri. Dalam hal ini penggunaan merkuri dalam proses pengambilan emas murni dari batuan telah mempengaruhi air sungai sehingga memiliki kandungan 0,002-1 mg/l Hg;0,05 mg/l Pb; 0,4 mg/l Cu and 28,39 mg/l Fe. Berdasarkan peraturan -pemerintah No. 822001 tentang pengelolaan kualitas air dan air irigasi, konstituen metal tersebut telah melebihi baku mutu air. Penggunaan mineral zeolite sebagai adsorben pada proses penambangan emas tradisional menunjukkan bahwa zeolit dengan ukuran 80- 100 mesh dapat mengurangi kadar hg sehingga masuk ke dalam baku mutu air.   ABSTRACT The gold mine activity of people in jendi village has been conducted since 1993. Even though this activity provide job for the local people. It will degrade the environmental quality especially river, because of Mercury use. The use of Mercury in the process to extract natural gold from concentrate of rock mill affects river water because it contains 0.002-1 mg/l Hg; 0,05 mg/l Pb; 0,4 mg/l Cu and 28,39 mg/l Fe.

    Full Text Available ABSTRAK  Biomassa adalah sumber energi utama jutaan manusia di dunia, akan tetapi penggunaannya menurun ketika batubara, minyak dan gas tersedia cukup melirnpah. Namun akhir-akhir ini perhatian muncul kembali karena terjadinya krisis energi dan isu-isu lingkungan. Pemanfaatan biomassa untuk menggantikan bahan bakar fosil dapat menurunkan persoalan emisi CO2 global. Penelitian ini bertujuan untuk mengkaji alternatif sumber energi terbarukan dengan pemanfaatan limbah biomassa cangkang kakao dan kemiri. Penelitian dilakukan dengan menghaluskan biomassa dengan ukuran partikel kurang dari I mm. Kemudian 5 gram campuran bahan baku dengan bahan pengikat gel tepung kanji dengan perbandingan 70:30 untuk kakao dan 80:20 untuk kemiri dibriket dalarn cetakan berdiarneter l6 mm. Setelah dibriket kemudian dikeringkan dengan oven pada suhu 50 oC selama 5 jam. Pembakaran dilakukan dalam ruang bakar pada temperatur dinding 350 oC dan laju aliran udara bervariasi antara 0,1 - 0,4 m/s. Hasil penelitian menunjukkan bahwa cangkang kakao dan kemiri mempunyai nilai kalor masing-masing 16.998 dan 21.960 kJ/kg. Emisi CO cukup signifikan pada tahap devolatilisasi. Cangkang kakao memberikan total emisi CO lebih tinggi dibandingkan dengan cangkang kemiri. Laju aliran udara juga berpengaruh terhadap emisi CO yang dihasilkan. Penambahan laju aliran udara akan mengurangi emisi CO, hal ini karena adanya penambahan suplai oksigen sehingga pemnbakaran dapat berlangsung lebih sempurna.   ABSTRACT  Biomass was the  primary source of energy for millions of people in the world, but when coal, oil, and gas became widely available, its use was declined. However, in recent years interest in biomass utilization increases because of energy crisis and environmental issues. Utilization of biomass for substituting fossil fuel can reduce global CO2 emission problem. The objective of this research is to study alternative energy sources that utilize biomass waste from cocoa and candlenut

    Full Text Available Peran industri kecil di beberapa wilayah Kabupaten Semarang sangat penting dalam menunjang perekonomian, khususnya di sekitar lokasi industri tersebut. Salah satu industri kecil yang memiliki potensi berkembang adalah industri tahu. Di Jawa tengah ada sekitar 500 industri tahu, yang sampai saat ini masih terus mengembangkan kapasitas produksinya. Industri tahu adalah salah satu industri kecil yang berpotensi menyebabkan masalah lingkungan. Hampir seluruh industri kecil, terutama industri tahu, sebagian besar tidak memiliki instalasi pemanfaatan limbah dan pengolahan limbah, karena dibutuhkan investasi yang besar untuk membangun unit tersebut. Dengan melihat masalah tersebut, pendekatan yang dapat menyelesaikan masalah tersebut adalah dengan cara menerapkan produksi bersih. Kajian penerapan teknologi bersih ini dilakukan dengan metode quick scanning pada setiap tahapan proses produksi. Proses  produksi  tahu terdiri  dari  pemilihan kedelai, penimbangan kedelai, perendaman, pencucian, penggilingan, ekstraksi, penyaringan, pemasakan, penggumpalan, pemisahan whey, pembungkusan, pengepresan, pemasakan, dan pengemasan. Pada proses pembuatan tahu di industri ini memiliki perbedaan dari pembuatan tahu di Industri tahu lain, yaitu terdapat penambahan garam dan bawang putih untuk menambah sedap produk tahu. Hasil kajian penerapan produksi bersih di industri tahu adalah good house keeping, recycle, reduce dan reuse. Berdasarkan beberapa kriteria kelayakan, alternatif penerapan produksi bersih untuk industri ini berupa modifikasi tungku yang dilengkapi dengan cerobong asap, modifikasi alat penyaringan dengan mesin, dan pembangunan instalasi digester untuk penghasil biogas. Kesimpulan kajian ini industri tahu ini belum mengenal produksi bersih. Manfaat yang diperoleh dari penerapan produksi bersih berupa penghematan bahan bakar, peningkatan rendemen filtrat tahu, dan kebersihan lingkungan.

    Full Text Available Tulisan ini merupakan tinjauan terhadap lebih dari 60 penelitian yang pernah dilakukan di Indonesia yang berkaitan dengan masalah pencemaran air. Dalam tinjauan ini terungkap bahwa hampir semua jenis sumber air, yaitu sungai, danau, tambak, laut maupun air tanah (misalnya sumur yang pernah diteliti, telah mengalami pencemaran. Pencemarnya terdiri dari semua jenis pencemar, baik bakteriologis, fisis maupun kimiawi. Pencemar bakteriologis terutama datang dari pembuangan tinja manusia. Bukan hanya karena letak sumber air yang berdekatan dengan pembuangan tinja yang menyebabkan pencemaian, melainkan juga karena perilaku masyarakat. Namun dicatat pula bahwa penelitian dalam bidang ini masih terlalu sedikit. Khususnya yang berkaitan dengan besarnya masalah. Pencemar fisis dan kimiawi terutama berasal dari pabrik-pabrik. Yang banyak mendapat perhatian tampaknya adalah logam-logam berat. Walaupun dijumpai kandungan beberapa logam berat dalam air ma­sih di bawah standar, tetapi beberapa yang lain cukup potensial atau telah melewati batas-batas standar dan bahkan telah menimbulkan dampak negatif terhadap kesehatan masyarakat. Hal ini terutama dikarena­kan banyaknya pabrik-pabrik yang membuang limbah industrinya langsung ke sungai dan badan-badan air lain tanpa pengolahan terlebih dulu atau dengan pengolahan yang tidak sempurna. Selain deterjen, sampah rumah tangga, pestisida dan pupuk sebagai pencemar, yang masih kurang mendapat perhatian peneliti, akhir-akhir ini muncul masalah baru yang tampaknya lebih menarik minat para peneliti, yaitu intrusi air laut. Dari beberapa penelitian yang telah dilakukan terungkap bahwa masalah ini pun sudah cukup serius, khususnya di daerah dekat pantai.

The pasteurization and packaging improvement could be expected can maintain the quality and extend the tempoyak’s shelf life. This research used polyethylene terephtalate (PET and polyamide as packaging materials; with modified atmosphere packaging (MAP, non MAP, vacuum and non vacuum. The parameters quality of tempoyak were observed by value of pH, sugar content, lactic acid, alcohol, lactic acid bacteria growth and total plate count. The result showed that the best quality of tempoyak was produced by product with pasteurization treatment. Lactobacillus genus with L.plantarum, L. casei, and L. fermentum were the dominant species of lactic acid bacteria. The result also showed that after the tempoyak was fermented during 84 hours, then the pasteurization should be conducted to stop the fermentation. The 84th hours was a constant phase in which that was the right time to inhibit the acid lactic bacteria growth. Pasteurized tempoyak packaged in PET with MAP technique had the longest shelf life as much as 84 days than others treatment whose had aboutonly 14 untill 56 days. The decreasing of tempoyak quality at 84 days was showed by colour change of tempoyak from yelowness to brown, pH decreased from 3.97 to 3.73, lactic acid content decreased from 1.49% to 0.99%, sugar content decreased from 16.57% to 3.28%, alcohol content of 0.32%, number of lactic acid bacteria decreased from 174.3×104cfu/g to 8.6×102 cfu/g, and total plate count from 177×104 cfu/g to 182.3×103 cfu/g.

    Full Text Available One of the alternative media, which is potential to be developed is the use of natural fiber materials from the environment (indigenous material. This natural fiber in foreign country such as Thailand, Japan, United States has crossed the threshold of the quality as a work of art that create by an artist. Meanwhile in Indonesia it is still brand new to be develop as a media of art expression. Indeed, art paper has already developed in Indonesia, but it is still a boundary production of pieces of paper that will be directly applied as a handicraft media. Moreover, the preparation process is still using the conventional method using chemical materials such as NaOH, Hypochloride, Boric acid, Chlorin, H2O2, etc., which burden the environment. Therefore an alternative, environmental friendly process is necessary to be developed to exploit natural fiber materials as a media of art expression. For this reason in this project a research on fiber-pulping process using xylanase enzyme has been carried out. The use of xylanase is enable to decrease chlorin consumption and reduce  chloro-organic concentration in pulp and waste, that also means a reduction in  production cost. The pulp was then used to make a paper to be tested for its quality by the Center for Pulp and Paper (Balai Besar Pulp dan Kertas, BBPK. This research resulted in a enzyme formulations for the fiber-pulping and preparation from variety of fiber materials: banana’s stalk, the abacca, hyacinth, straw, pineapple fiber and gold cocoon, b data of paper quality, and c work of arts from fiber/pulp material. In conclusion, enzyme can be applied in fiber-pulping process for lower impact on the environment and the workers.

The gold ore from the mining was processed with a direct amalgamation method, so it produced low gold concentrate, but the concentrate of mercury discarded to the river was high enough. Monitoring result of water and sedimentation in Ciliunggunung River in 2004, showed that the river was contamined by mercury (Hg, and the contamination was above the value limit. This happened especially in August 2005 where the Hg content was about 0.218 mg/l on the Ciliunggunung River in CLG.07. The chemical analysis result of heavy metals for the water of the Ciliunggunung River in CLG.07 was known to contain Fe above the standard drinking water criteria, meanwhile Mn, Cu, Pb, and As were still under the maximum drinking water criteria value. To decrease the mercury contamination, it is suggested the process of gold ore from the amalgamation direct method to be changed to the amalgamation indirect method. The indirect gold ore amalgamation process consists of: removing fine particles by washing, grinding ore, and the amalgamation phase. The total impact of the indirect amalgamation method will increase the tying of gold by mercury, so the losing of mercury will be decreased and the gain of gold will be optimum.

Gourami (Osphronemus Gouramy scales are one of the natural sources of collagen. This fish scale’s collagen has functional properties, such as bio-degradable (easily decomposed, bio-compatible (compatible with surrounding tissue, and potential as bio-adsorbent. The absorbent properties of collagen are currently used as a transport material in local drug delivery for periodontal disease treatment, which is known as tetracycline chip. However, this chip is made of synthetic collagen so it is not absorbable by the body’s system. The price is also expensive. This study’s aim is to prove the potency of Gourami scales as a source of collagen in medical treatment, especially as a transport material of tetracycline for periodontal disease treatment. The gourami scale was obtained from seafood restaurant in Jember, Jawa Timur. About 500 mg of gourami scales was immersed into 20 ml tetracycline solution in beaker glass. About 200 μl solution from the beaker glass was taken with micropipette after 1-hour, 2-hour, 4-hour, 12-hour and 24-hour after immersed. After that, the solution was collected into an eppendorf for each time. The absorbance was measured with spectrophotometer at 450 nm wave length. This procedure was repeated five times. The lowest absorbance occured at 1-hour time (160,6 μg/μl. The result from light and inverted microscope examination shows a bond between collagen from gourami scales with tetracycline. Gourami scale has the ability to absorb the highest rate of tetracycline at 1-hour immersed time by forming a bond between collagen and tetracycline.

    Full Text Available Empty fruit bunch (EFB and shell of oil palm are potential sources of bioenergy because they contain lignocellulose (cellulose, hemycellulose and lignin which can be converted to bio-oil (liquid, char, or combustible gases by pyrolysis process. Operating temperature of the pyrolysis process will influence the composition of the liquid, char and gases, as well as its characteristics. The objective of this study is to characterize the pyrolysis product of both empty fruit bunch and shell as affected by the pyrolysis temperature. The experiment was conducted by using a lab scale pyrolysis reactor, specially designed with controlable temperature. The temperature of the pyrolysis process was controled at 300°C, 400°C, 500°C, and 600°C level, and the product was measured and analysed. The result showed that pyrolysis of shell produced char, liquid and gases at the range of 34.99 - 63.78%, 22.76 - 43.28% and 13.47 - 21.73%, in mass fraction respectively. While pyrolysis of empty fruit bunch produced char, liquid and gases at the range of 30.66 - 64.7%, 16.25 - 29.16% and 18.98 - 44.49%, in mass fraction respectively. Increasing temperature resulted in increasing calorific value of the pyrolysis char from shell and empty fruit bunch in range of 25.64 – 29.60 kJ/g and 24.50 – 27.86 kJ/g, respectively. However, the calorific value of pyrolysis gases was decreasing with the increasing temperature in range of 12.18 kJ/g – 20.05 kJ/g and 11.98 kJ/g – 15.94 kJ/g, respectively. The gas calorific value did not account H2 gas, which might be the cause of the phenomenon. Shell pyrolysis temperature increasing caused the increasing of CO concentration in range 2.86% - 18.42% while the CH4 concentration increased at 400°C level afterwards decreased at higher temperature level in range of 0.89% - 2.84%. The increasing of EFB pyrolysis temperature increased CO dan CH4 concentration in range 3.8% - 15.74% and 0.29% - 0.76%, respectively.

    Full Text Available http://dx.doi.org/10.17014/ijog.vol1no1.20064aWhen tailing of a mining activity is discharged into either landscape or river body, the pollutan element wastes are possible to disperse within those areas and may cause pollution on environment. The environment pollution hazards of arsenic (As, mercury (Hg, lead (Pb and cadmium (Cd probably occurred if tailing with the content of those elements is not handled properly. Particularly in the tropical regions, higher rates of chemical weathering and bio-chemical activity will contribute a rapid mobilization of the most potentially toxic elements.One of adverse health effects from arsenic to human life is in the case of arsenic-contained drinking waters exceed the threshold limit value. As a result, it will create chronic symptoms of toxicity within the human body such as gastro-intestinal irritation, nerve damage and tissue wastage. Tailing originated from amalgamation processing of gold ore enables its mercury waste to disperse in the vicinity of mining area and may form environment pollution by either organic or inorganic mercury. The pollution would be more hazardous to human health if mercury element in the water body transform biochemically into a compound of methylmercury. There is a variety of mechanisms by micro-organism which can bring about the formation of the very toxic methylmercury species, particularly with regard to its uptake by fish. Effects to the human health from the organic mercury include the blood-brain barrier and upsetting the metabolism of the nervous system. Whilst the main toxic effect of inorganic mercury is disruption the functions of kidneys and liver within human body. Most mining activity of base metal may discharge tailing with a significant lead (Pb content. Lead is a cumulative poison, hence absorbing this element by human body with particularly exceeding its threshold limit value will bind strongly to a large number of molecules such as amino acids, haemoglobin, many enzymes, RNA and DNA. Then it will bring into disruption of many metabolic pathways, blood hypertension, hyperactivity and brain damage. Problems of cadmium could arise from a lead-zinc mining and smelting operation, from where pollution due to cadmium-contained tailing with additional aerial pollution associates with cadmium-contained fumes and particles. The toxic effects of cadmium to human health are suffering from lumbago-type pains, bone damage with multiple fractures of the softened bones and kidney failure.

    Full Text Available People's habits in consuming Aceh noodles make the noodle industry grow rapidly, but the waste treatment process becomes less effective. In the process of making the noodles, dye waste is produced in the form of tartrazine dye and need to be processed before being disposed into the environment. The research purpose was to describe the decomposition of tartrazine using ozonolysis and solar radiation methods as one of the solutions in the waste treatment process. The use of ZnO as catalyst is to accelerate the decomposition reaction of the noodle washing wastes. The results of the analysis concluded that ozonolysis methods are more effective in decomposing tartrazine in the noodle wash wasted by solar irradiation method. The sun exposure decomposed tartrazine by 99.74% using 0.015 g ZnO for 150 min and tartrazine content obtained 0.022 mg/L with a sunlight intensity of 1.24 x 1016 cm-2 s-1. Ozonolisis exposure decomposed tartrazine by 98.68% using 0.020 g ZnO for 12 minutes and tartrazine content obtained 0.112 mg / L.
