Abstract

Panti sosial perlu meningkatkan kemandirian, sehingga bisa mengurangi ketergantungan terhadap pendanaan dari pemerintah. Capacity building yang berkelanjutan merupakan salah satu kegiatan yang dapat dilakukan dalam rangka pemberdayaan panti-panti sosial yang selama ini merupakan cost center. Berdasarkan hasil diskusi dan survey yang dilakukan secara langsung, maka diperoleh informasi bahwa sebagian besar panti sosial sudah berupaya membangun kemandirian melalui beberapa kegiatan, diantaranya adalah pengelolaan bank sampah, minyak jelantah, keterampilan bengkel, dan lain sebagainya. Dan yang sudah selesai dilakukan adalah kegiatan hibah Matching Fund Kedaireka yang berjudul Green-Techno Sosiopreneur Ternak Magot Bangkitkan Ekonomi Mandiri Panti-Panti Sosial. Salah satu luaran dari kegiatan ini adalah produk inovasi mesin pencacah. Dalam rangka meningkatkan utilitas penggunaan mesin pencacah, khususnya pada PSAA PU 3 Ceger, maka kegiatan Pengabdian kepada Masyarakat (PkM) ini difokuskan kepada pengolahan kompos. Kegiatan ini diharapkan mendatangkan keuntungan ekonomis berwawasan lingkungan terhadap panti. PkM ini diikuti oleh 47 orang peserta. Peserta memberikan nilai baik untuk pelaksanaan kegiatan ini. Pada PkM berikutnya peserta mengharapkan materi lanjutan tentang pengolahan sampah (waste to value) dan bagaimana cara memasarkan produk hasil pengolahannya.

Abstract

High free fatty acids in waste cooking oil can interfere with the re-use of the cooking oil. Therefore, the absorption technique is one way that can reduce the free fatty acids contained in waste cooking oil. Aim: The purpose of this study is to find out the ability of Reactivated Spent Bleaching Earth (RSBE) to adsorb free fatty acids contained in waste cooking oil to be biodiesel products. In this study, waste cooking oil was collected from fried food sellers in Bekasi, while spent bleaching earth (SBE)-one of the solid wastes produced by refinery oil palm industry as an adsorbent-was from the palm oil industry PT X. For Reactivated Spent Bleaching Earth (RSBE), the redundant used 0.7 M HNO3. To obtain the optimum products, The redundant applied the variation of time (i.e., 30, 45, 60, 75, and 90 minutes) and concentration (6%, 9%, 12%, 15%, and 18%). Methodology and results: Results indicated that the time variation of temperature 90 minutes were the maximum and the concentration of 15% were the optimal combination to reduce free fatty acids 0.65%. Conclusion, significance, and impact of study: The values of water and ash contents of RSBE also meet the quality standard as activated carbon and can be used as an adsorbent for the purification of waste cooking oil. The oil content in SBE is less than 3% and is considered not to be a toxic hazardous waste. Therefore, it can be reused without pre-treatment. In addition, the redundant found that there were changes pore on the surface of the SBE, both activated and not activated. To conclude, SBE can be used as an absorbent to absorb the fatty acids in waste cooking oil.

Abstract

Black Soldier Fly (BSF) larvae are known to have the ability to process food loss and waste and reduce the weight of food loss and waste, by producing decomposition products that have beneficial values. Food loss and waste needs to be reduced to reduce the burden of waste entering the Final Disposal (TPA). Aim: The purpose of this study was to determine the ability of BSF larvae and to determine the quality of the decomposition results in processing food loss and waste in the Taman Sari District on a laboratory scale. Methodology and Results: Taman Sari Distrisct is a high dense populated area Total days of bioconversion activity is 12 days, giving back 1,000 grams of municipal waste organic, containing food loss and food waste, according to variation is given repeatedly on the 1st, 5th, and 8th days for each 12 sample code. The amount of 5 days old (5-DOL) maggot used for each sample code is 30 grams. Conclusion, significance, and impact study: The percentage reduction in processing from 3 kg of food loss and waste can reach 86% with the average residue produced in the form of 415.67 grams of solid compost and 221.7 grams of prepupa. Bred prepupa will evolve into several stages: pupa, fly, egg, baby larvae, and 5-DOL for 57 days on its life cycle.

Abstract

Nagrak and Ciangsana Village located in Gunung Putri Sub-district, Bogor Regency, West Java. The area of Nagrak Village is 5.84 km2 and the area of Ciangsana Village is 8.62 km2. The level of waste service in both villages is 12%, the planned service level target at the end of the planning year 2032 is 100%. This planning data collection uses the SNI 19-3964-1994 method regarding data collection methods in operational technical planning for waste management. Sampling using the stratified random sampling method, the waste generation rate in Nagrak Village and Ciangsana Village is 2 liters/person/day with a total population of 51488 people from the two villages, the waste generation from domestic areas has 54% organic waste and anorganic waste has 46%. The waste generation from Non-domestic areas has 60% organic waste and anorganic waste has 40%. Organic waste is processed with Black Soldier Fly (BSF), anorganic waste is processed with the Refused Derived Fuel (RDF) method at TPST 3R Trisakti. The planning stage consists of short term (2022-2024) medium term (2025-2028) and long term (2029-2032). The cost budget plan includes investment, operational and maintenance costs with a total cost of Rp.59,424,025,515. The selected alternative is alternative I, which has a more economical and affordable cost budget for Nagrak Village and Ciangsana Village.
