Abstract

RBP-52 and P15 isolates were Isolated from Indonesian fruits samples that contains glucose. RBP-52 Isolate wasobtained from coconut water waste, collected from nata factory, and PDS Isolate was obtained from rotten coconut sample,collected from Pansng. They were identified as Acetobacter liquefaciens. RBP-52 and PD5 Isolate produced cellulose in staticand shaking cultivation. Production of cellulose by RBP 52 and P15 were optimized in static cultivation. Cellulose wasfound to be produced at the liquid surface In static cultivation. The rate of cellulose production depended proportionally onthe surface area or the culture medium. The maximum production rate of cellulose was 2.78 gIl per 7 days surface area77.60 cm3 in the static cultivation

Abstract

Malodorous gases emitted from natural rubber industries. At crumb rubber plant, leum storage emits high concentration of  ammonia that strength odor and dangerous to healthy workers. This research occurred to remove ammonia from leum storage using biofilter coloum 23L packed with mixed of top-soil, peat-rubber leaves and sludge. The result shows that this biofilters can remove ammonia  from inlet concentration at 4 - 20 ppm to  outlet concentration less than 4,7 ppm (average of 1,1ppm below regulation limit of 2 ppm). The biofilter packed with top soil performs  to ammonia removal efficiency average of 89% and ammonia-removal capacity at 0,36 g-N/kg-dry-material/d. The biofilter packed with mixed of top soil and rubber leaves performs  to ammonia removal efficiency average of 85% and ammonia-removal capacity at 0,60 g-N/kg-dry-material/d. The biofilter packed with mixed of top soil and sludge performs  to ammonia removal efficiency of 99% and ammonia-removal capacity at 0,36 g-N/kg-dry-material/d. The biofilter packed with mixed of top soil and sludge indicated the most stable on ammonia removal capacity and the lowest oulet ammonia at an average of 0.1 ppm.   Keywords:.

Abstract

Co-composting was the composting process uses two or more raw materials to improve the optimization process and material benefits. The purpose of this study was to determine the influence of the initial C/N value ratio and the active aeration usage of the co-composting process of filter cake and boiler ash of cane sugar industry. Co-composting  was done in the aeration pile reactor with 5 kg of mixed material,and uused two factor; initial C/N ratio and aeration. The treatment of  C/N ratio was begun at 30, 40, and 50 from formulation filtercake and boiler ash.   Active aeration was given at 0.4 and 1.2 l /minutes.kg materials that carried out for 1 hour per day  on the first week. From this observation, known that the aeration distiction at 0.4 and 1.2 l /minutes.kg materials does not effect the C/N ratio of  compost.  In the other hand,  the treatment of initial C/N ratio at 30 and 40 was significantly affected with initial C/N ratio at 50 compared by final  C/N value of the compost. Initial C /N ratio at 50 requested the final  C / N ratio of compost at 19-20 that was higher than the treatment of  intial C/N ratio at 30 and 40 which had final C/N ratio at 13-15 and 12-17, respectively.

Abstract

Indonesia as one of the developing countries has a high dependence on petroleum fuels derived from petroleum refinery as the main energy source. the use of foil in Indonesia is dominated to meet the needs of transportation vehicles. Fuel oil as a source of energy into the spotlight in the world lately because of the impact of environmental degradation that arise from the utilization. The industrial activity of fuel oil production in refineries is inseparable from the environmental impacts. The oil processing process at the refinery is the second highest emission contributor after the use of fuel oil itself during its product life cycle. In this research LCA analysis is conducted for the production of gasoline (bensin) and gasoil (diesel) vehicle fuels during processing at the refinery to compare the environmental impact of each type of fuel. From the result of LCA analysis, it is known that from two types of vehicle fuel, to produce 1 kilo litter of gasoline (bensin) type more energy and produce higher emission compared to diesel type gas (gasoil) fuel production. The gasoline fuel produced in the platformer unit is the product that has the highest emission contribution in its production process with greenhouse gas emissions of 1 Ton CO-2eq and the acid gas emissions of 0.001 Ton SO-2eq per 1 kilo litter of the resulting product.

Abstract

Pemisahan unsur radioaktif dan logam tanah jarang yang dilakukan di PLUTHO menghasilkan limbah yang masih mengandung torium dan uranium. Limbah yang dihasilkan memerlukan pengolahan lanjutan agar ramah lingkungan. Tujuan penelitian adalah menurunkan kadar torium dan radioaktivitas dalam limbah cair proses pengolahan monasit pilot plant PLUTHO menggunakan koagulan fero sulfat. Pilot Plant PLUTHO merupakan suatu fasilitas yang didirikan untuk untuk memisahkan uranium, torium, dan logam tanah jarang (LTJ) dari mineral monasit dan mineral lainnya dalam skala pilot. Perlakuan variasi yang dilakukan pada penelitian adalah dosis koagulan dan pH. Pengukuran kadar torium dilakukan dengan metode Spektrofotometer UV-Vis, sedangkan pengukuran radioaktivitas dilakukan dengan alat ukur radiasi Ludlum Model 1000 Scaler. Hasil penelitian menunjukkan kondisi optimum koagulasi pada pH 8,0 dengan dosis koagulan FeSO4 225 mg/L yang dapat menurunkan kadar torium sebesar 45,20 % dan menurunkan radioaktivitas sebesar 100 % dari kadar torium dan radioaktivitas awal yaitu 0,73 mg/L dan 1,35 Bq/g. The separation of radioactive and rare earth mineral carried out in PLUTHO produces waste that still contains thorium and uranium. The resulting waste requires further processing to be environmentally friendly. The purpose of study is to reduce thorium content and radioactivity in liquid waste of PLUTHO monazite treatment process using ferro sulphate coagulant. PLUTHO Pilot Plant is one of facility that built to dissociate uranium, thorium and light rare earth from mineral of monazite. Variations of treatments applied in the research are coagulant dosage and pH. Thorium content is measured by Spectrophotometer UV-Vis method, whereas radioactivity is measured by radiation counting meter Ludlum Model 1000 Scaler. The result shows that the optimum condition of coagulation is in pH 8,0 with concentration of ferro sulphate 225 mg/L which may reduce thorium content up to 45,20 % and reduce radioactivity to 100 % out of its initial thorium content and radioactivity as much as 0,73 mg/L and 1,35 Bq/g, respectively.

Abstract

PT Sinkona Indonesia Lestari adalah anak perusahaan dari dua Badan Usaha Milik Negara yaitu PT Kimia Farma dan PT Perkebunan Nusantara VIII. PT Sinkona Indonesia Lestari (SIL) memproduksi cinchona atau yang dikenal dengan tanaman kina yang merupakan tanaman obat yang mengandung quinine yang dikenal sebagai obat malaria. Cinchona diekstraksi untuk diambil kandungan quinine. Setiap tanaman cinchona mengandung kadar quinine 3-14%. Penilaian jumlah emisi yang dikeluarkan selama proses produksi dapat dilakukan dengan menggunakan metode Life Cycle Assessment (LCA). Selain itu, LCA juga akan digunakan untuk melakukan perbaikan dalam siklus hidup produksi yang bertujuan untuk mengurangi emisi. Tujuan penelitian ini adalah untuk menilai dampak lingkungan berupa gas rumah kaca (GRK), serta upaya untuk mengurangi dampak lingkungan tersebut. Tahapan dari penelitian ini adalah menentukan tujuan dan ruang lingkup, analisis inventori daur hidup, analisia penilaian dampak lingkungan, dan analisis interpretasi hasil. Dari analisis LCA, untuk menghasilkan 1 ton garam kina diketahui menghasilkan dampak lingkungan berupa emisi gas rumah kaca sebesar 47.3815 CO2(eq) pada tahun 2013. Pada tahun 2014 emisi gas rumah kaca mengalami penurunan sebesar 53.4217 CO2(eq). Pada 2015, 1 ton garam kina menghasilkan emisi gas rumah kaca sebesar 53.5435 CO2(eq) dan pada 2016 menghasilkan 45.7901 CO2(eq). Penelitian ini juga menemukan bahwa pemanfaatan ampas kina dan penggantian minyak residu menjadi bahan bakar solar dapat mengurangi emisi. Pembuatan briket dari ampas kina dapat menurunkan emisi gas rumah kaca sebesar 0,14 % pada tahun 2015 dan menghasilkan energi alternatif sebesar 1.612 TJ. Alternatif lain adalah penggantian minyak residu menggunakan bahan bakar solar (IDO) pada bahan bakar boiler, yang dapat mengurangi emisi sebesar 11.9% atau 6.3518 ton CO2 (eq) /ton garam kina.
