This paper deal with incineration of the oil palm empty fruit brunches into biochar as carbon fertilizer for planting medium. The inceration process uses carbonized technology at temperature of 400 °F, developed by Ishenny Noor (2015). Application of 22-23% biochar as carbon fertilizer could increase soil carbon content from 0,4-0,7% to 2% / Ha, physical and chemical soil quality, ground water storage, fertilizer activity of soil microorganisms, soil nutrients. Application of biochar on rice plantation yielded 10 tons / ha of black rice / Ha, while application on oil palm plantation yielded oil palm fruit bunch of 20 to 40 kg / bunch. Production of biochar from oil palm empty bunches could give an extra profit for a palm oil processing factory by Rp. 471,926,000 a year (with a capacity of 100 tons/hour of the oil palm empty bunches in 24 hour operation a day) with the ROI of 78%/years, and B/C ratio of 1,71.
AbstrakPengolahan limbah yang tercantum di dalam Standar Nasional Indonesia SNI 3242:2008. meliputi kegiatan pemisahan, daur ulang dan composting. Kondisi ini masih meninggalkan sampah B3 ke rumah sakit atau ke tempat penampungan akhir (TPA). Penyelesaian masalah limbah non-B3 dan B3 harus dengan teknologi yang ramah lingkungan. Penelitian ini bertujuan untuk memberikan solusi atas penanganan limbah dari sampah domestik non-B3 maupun B3 di rumah sakit yang saat ini mengacu pada SNI 3242:2008. Penelitian ini dilakukan di Rumah Sakit Umum Kota Langsa Propinsi Aceh. Metode penelitian mencakup kajian teknologi pengolahan limbah yang dapat mengatasi limbah non-B3 dan B3, analisis biokatalis dalam menurunkan energi aktivasi den kajian teknologi karbonisasi. Hasil penelitian menunjukkan bahwa teknologi karbonisasi mampu merubah sampah non-B3 dan B3 menjadi produk yang bernilai ekonomi serta bermanfaat untuk memperbaiki lingkungan. Teknologi karbonisasi tidak menghasilkan polusi dari prosesnya sehingga layak digunakan di rumah sakit karena sesuai dengan SNI yang terkait dengan persyaratan emisi gas buang (SNI 19-7117.2-2005). Manfaat lain yang diperoleh dengan menerapkan teknologi karbonisasi adalah biokarbon, asap cair, pupuk cair, syngas dan steam (pasteurisasi di rumah sakit).

AbstractWaste treatment listed in Indonesian National Standard SNI 3242: 2008. including separation, recycling and composting activities. This condition still leaves the B3 waste to the hospital or to the final shelter (TPA). The solving of non-B3 and B3 waste problems must be with environmentally friendly technology. This study aims to provide solutions for handling waste from non-B3 or B3 domestic waste in hospitals that currently refer to SNI 3242: 2008. This research was conducted at Langsa General Hospital of Aceh Province. The research method includes the study of waste treatment technology that can overcome the non-B3 and B3 wastes, biocatalyst analysis in reducing the activation energy and carbonation technology study. The results show that carbonization technology is able to transform non-B3 and B3 waste into economic value and useful products improve the environment. Carbonation technology does not produce pollution from the process so it is feasible to be used in hospitals because it is in accordance with SNI related to exhaust emission requirements (SNI 19-7117.2-2005). Other benefits gained by applying carbonization technology are biocarbon, liquid smoke, liquid fertilizer, syngas and steam (pasteurization at the hospital).
been carried out. The purpose of the study was to find the best formulae of the soft candy. The properties of the soft candy especially the moisture content, ash content and toxicity were exxmined. The results show that the formulae with sorbitol and curcuma of 39.5 g and 1 g respectively (A3B3) has the highest moisture content that is 14.52%, while the lowest is 11.89% which was obtained in the formulae containing curcuma of 0.5 g and sorbitol of 37.5 g (A1B1). The highest ash content was obtained in the formulae containing sorbitol of 38.5 g and curcuma of 0.5 g (A2B1). The value is 1.1739%.The lowest ash content was found in the formulae containing 38.5 g of sorbitol and 1 g of curcuma (A2B3), the value is 1.505%. The toxicity test results show that the soft candy has no bio-active properties. The LC50 of the candy is more than 1000 ppm. Based on hedonic/organoleptic test, the soft candy with sorbitol and curcuma of 75% and 0.25% respectively is the most prefered.
