Hingga saat ini upaya pengelolaan sampah di beberapa daerah di Indonesia belum menunjukkan hasil yang optimal, termasuk salah satunya adalah upaya pengelolaan sampah yang ada di Desa Cibodas, Kecamatan Pasirjambu, Kabupaten Bandung. Sampah masih dianggap barang yang tidak memiliki nilai ekonomi dan belum menerapkan prinsip 3R, seperti pengurangan, penggunaan kembali serta melakukan daur ulang, sehingga berpotensi menimbulkan pencemaran lingkungan. Untuk membangun sistem pengelolaan sampah berbasis masyarakat yang ramah lingkungan di Desa Cibodas, upaya yang dijalankan meliputi: membentuk kelompok penggerak, membangkitkan minat dan kesadaran masyakarat, memetakan potensi, meningkatkan pengetahuan dan pemahaman masyarakat, serta merencanakan Tempat Pengolahan Sampah (TPS)-3R sebagai unit percontohan. Atas inisiatif masyarakat desa, kelompok penggerak dipilih kelompok karang taruna desa. Kelompok karang taruna ini selain melakukan pengawasan pelaksanaan pemilahan sampah di tingkat warga, juga dilibatkan dalam menentukan jenis teknologi pengolahan sampah yang akan diterapkan di TPS-3R

Pasar traditional mempunyai kontribusi yang besar sebagai penghasil sampah, demikian juga Pasar Leuwiliang (luas 21.714 m2), Cigudeg (luas 11.000 m2) dan Jasinga (luas 18 m2) yang berada di Kabupaten Bogor. Tujuan dari penelitian ini adalah mengetahui potensi sampah untuk dimanfaatkan kembali dan merancang pengelolaan sampah terpadu sesuai dengan karakteristik dan komposisi sampahnya. Metode pengambilan sampel sampah berdasarkan SNI 19-3964-1994. Hasil penelitian diperoleh timbulan sampah Pasar Leuwiliang sebesar 46,36 m3/hari, Pasar Cigudeg 57,73 m3/hari dan Pasar Jasinga 120,65 m3/hari. Laju timbulan sampah Pasar Leuwiliang sebesar 184,08 liter/m2/hari, Pasar Cigudeg sebesar 262,79 liter/m2/hari dan Pasar Jasinga sebesar 311,118 liter/m2/hari. Rata-rata komposisi sampah organik ketiga pasar tersebut sebesar 71% dan 29% non oganik. Perencanaan teknis pengelolaan sampah terdiri dari pemilahan, pewadahan, pengumpulan sampah, pengangkutan sampah dan pengolahan di Tempat Pengolahan Sampah Terpadu (TPST). Alat pengumpul direncanakan berupa gerobak dengan kapasitas 1 m3 sedangkan alat angkut direncanakan berupa dump truck dengan kapasitas 10 m3. Lokasi TPST direncanakan di Pasar Leuwiliang seluas 826 m2, dengan kapasitas ± 100 m3/hari yang akan melayani sampah dari Pasar Leuwiliang, Pasar Cigudeg dan Pasar Jasinga. TPST tersebut direncanakan akan memiliki 6 bak pengomposan. Sampah organik yang akan diolah di TPST sekitar 70% dari total timbulan sampah sedangkan sisanya akan dipilah menjadi dua bagian yaitu sampah non organik yang akan dijual ke lapak dan residu akan diangkut ke TPA Galuga Bogor. Potensi sampah yang dapat dimanfaatkan kembali dari ketiga pasar tersebut mencapai 88,94%-99,44%. Total kompos yang dihasilkan sebesar 1047,62 kg/hari dan total sampah non organik yang akan dijual ke pelapak sampah non organik adalah sebesar 708,95 kg/kg. Perencanaan TPST diharapkan dapat menjadi solusi dari masalah persampahan dan dapat memberi manfaat bagi masyarakat pasar maupun masyarakat sekitar pasar

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.

To increase service coverage and meet the increasing demand for drinking water, PDAM Tirta Kahuripan plans to build a Ciawi WTP in Megamendung District with a processing capacity of 165 L/second using the Sukabirus River as a raw water source. The purpose of this study was to determine the processing units in the design of the Ciawi WTP using multi-criteria analysis. Based on the results of the analysis of raw water quality, there were several parameters that do not meet the drinking water quality standards according to the Minister of Health Regulation No. 492 of 2010 and PPRI No. 82 of 2001, namely turbidity, Fecal coliform, total coliform, TSS, BOD, COD, and DO. There were three alternative processing circuits used. Alternative I consists of intake, hydraulic coagulation, up-down flow hydraulic flocculation, plate settler sedimentation, rapid sand filtration, disinfection, and reservoir. Alternative II consists of intake, hydraulic coagulation, vertical-shaft paddle wheel mechanical flocculation, tube settler sedimentation, rapid sand filtration, disinfection, and reservoir. Alternative III consists of intake, in-line static mixers coagulation, horizontal-shaft paddle wheel mechanical flocculation, plate settler sedimentation, rapid sand filtration, disinfection, and reservoir. There are other factors that must be considered in the selection of treatment units, namely contaminant removal, reliability, flexibility, construction, land requirements, ease of operation, maintenance, cost, and environmental compatibility. Based on multi-criteria analysis, the percentage of suitability for alternative I is 78%, Alternative II is 63%, and Alternative III is 48%. From this assessment, it can be said that alternative I is the best alternative.

Cibodas Village, Pasirjambu District, Bandung Regency is a Partner Village for the Faculty of Landscape Architecture and Environmental Technology (FALTL) which has a vision of making Cibodas Village an Eco-Village. Waste management is one of the main activities to create an Eco-Village. One of the main problems in waste management is the use of the collect, transport and throw concept that has been entrenched in our society. The community, as a waste producer, is not yet disciplined in disposing of waste in its place and is not accustomed to implementing the 3R concept (Reduce, Reuse and Recycle). Activities ranging from preparation to implementation and writing of reports were carried out from June 2020 to August 15, 2020. The forms of activities were counselling and training. The activity took place on time and was attended by around 30 participants. The activity could run well and was followed by extension participants, namely the village youth who were assigned to be facilitators. Surveys conducted on June 2nd, 2020, discussed for training preparation, training material and participants. From outreach activities that focus on Counselling on Waste Management and Environmental Cleanliness as Efforts to Prevent Transmission of Infectious Diseases that have been carried out by the PKM Team of the Environmental Engineering Department, FALTL, Trisakti University can broaden facilitators' insights regarding waste management and prevention of transmission of infectious diseases and PKM activities are initial efforts to realize Eco-Village through community empowerment starting with independent waste management through 3Rs and waste banks.
