Abstract

The problem of open defecation (BABS) and the lack of proper toilet infrastructure for the residents of Cikoneng Village, RT 2, Bandung Regency can have a negative impact, especially on the health aspect. The economic situation and lack of public awareness of cleanliness are factors that lead to many latrines being covered only by tarpaulins with bamboo/wooden walls. The communal latrines previously available in Cikoneng village were even less effective due to their non-strategic location and water quantity problems. The purpose of this research is to plan the construction of a Pour and Flush Toilet (PFT) in RT 02 by conducting observations, questionnaires and analysis of technical and non-technical aspects to achieve good sanitation. The results of the research show that 100% of the residents of Kampung Cikoneng RT 2 are aware of the importance of PFT and are willing to participate in the construction, which consists of 4 toilet units and a septic tank with a length of 8.5 m, width of 9 m and depth/height of 8.5 m.

Abstract

Akses sanitasi yang layak perlu dimiliki oleh setiap masyarakat di Indonesia. Penerapan Pour-Flush Toilet (PFT) atau jamban siram merupakan salah satu inisiasi Desa Cikadut dalam memenuhi kebutuhan akses sanitasi layak bagi warganya. Namun, penerapan jamban siram di suatu daerah dapat menjadi tidak berkelanjutan akibat tidak sesuainya bangunan jamban dengan standar pembangunan dan minimnya pasrtisipasi masyarakat. Tidak berlanjutnya teknologi sanitasi dapat menjadi penyebab dari sanitasi yang buruk dan menurunnya kesehatan warga. Penelitian ini bertujuan untuk mengevaluasi penerapan jamban siram di RT 02 RW 12 Desa Cikadut, Kecamatan Cimenyan, Kabupaten Bandung dari aspek teknis dan nonteknis. Keberhasilan aspek teknis dianalisis atas dasar kesesuaian kondisi eksisting komponen-komponen jamban siram dengan kriteria desain yang disarankan. Keberhasilan aspek nonteknis ditentukan berdasarkan potensi keberlanjutan penerapan jamban siram berdasarkan analisis hasil kuesioner dan wawancara terkait partisipasi dan kepuasan warga pengguna rutin jamban siram. Hasil penelitian menunjukkan 71,43% komponen jamban memenuhi kriteria desain yang disarankan. Desain cubluk masih kurang dalam 1,62 m serta belum pernah dilakukan penyedotan. Partisipasi masyarakat yang tinggi dari proses sosialisasi awal hingga proses perawatan jamban siram, tingkat kepuasan yang tinggi, serta pemimpin setempat yang aktif merupakan alasan utama berhasilnya penerapan sanitasi layak di RT 02 RW 12 Desa Cikadut. Penerapan jamban siram di RT 12 RW 02 Desa Cikadut belum berhasil pada aspek teknis dan berhasil pada aspek nonteknis.

Abstract

Permasalahan limbah domestik di Kota Cimahi harus direspon dengan penyediaan sanitasi yang layak, utamanya pengelolaan limbah domestik terpusat (SPALD-T) skala komunal yang menyediakan prasarana dan sarana pengolahan air limbah domestik berbasis masyarakat (Sanimas). Pada 2021, terdapat 14 sistem komunal baru yang harus didata untuk memperbarui data keseluruhan sistem yang terbangun. Oleh karena itu, perlu dilakukan pemutakhiran data dengan sistem informasi yang mengintegrasikan data spasial dan non spasial. Hal ini untuk menunjang ketersediaan database, mengidentifikasi permasalahan dan mengenali potensi perbaikan; serta memberikan masukan dalam menentukan dan merencanakan penempatan lokasi sarana serta prasarana air limbah di masa yang akan datang. Kondisi eksisting sistem jaringan dan sistem pengolahan diperoleh dengan pengamatan dan wawancara. Penilaian sistem dilakukan melalui skoring parameter keberfungsian sistem, jumlah sambungan rumah, kondisi jaringan, kondisi IPAL, kondisi keuangan pengelolaan IPAL, pemelihara IPAL, dan aspek kelembagaan.  Selain itu akan di data kepadatan penduduk dan status risiko sanitasi setiap kelurahan di integrasikan secara spasial dengan Arc GIS. Hasil skoring dan analisis Arc Gis keseluruhan sistem menunjukan bahwa sistem baru berfungsi sesuai tujuannya hanya masih lemah dari sisi keuangan dan kelembagaan dengan rata – rata skor 82,05%.  Selain itu, terdapat 1 kelurahan berisiko sangat tinggi (zona merah) namun tidak terdapat system baru di wilayah ini. Hasil ini menjadi dasar untuk perencanaan penempatan atau perbaikan sarana serta prasarana air limbah di Kota Cimahi.

Abstract

Abstract Rainwater harvesting system (RWH) is a technology to collect and store rainwater as an alternative clean water source. The aim of this study to plan RWH, including determining strategies, feasibility analysis based on rainwater quality and quantity, and planning basic engineering design of RWH. The planning was carried out in Jelegong Village, Bandung Regency, an area with critical water catchment conditions that has not been served by clean water piping networks, and only uses groundwater with limited availability as the only source of water in the dry season. Primary data were collected through field surveys and sampling of rainwater quality in the early rainy period (September, 2022). The selected catchment area is the roof surface of the house. In terms of quantity, with 55 houses served, the potential rainwater supply (4,318.88 m3 / year) can meet the needs of non-drinking water use (2,369.65 m3 / year) such as bathing activities, toilet needs, and laundry activities. In terms of quality, rainwater color parameters have not met the quality of clean water based on Permenkes 32/2017. Communal RWH is planned due to limited land and high population density. The collected rainwater will go through a disinfection and filtration process to meet clean water quality standards, then be stored in ground tanks (70 m3) and roof tanks (5 m3) to be distributed to each house. Thus, the planned RWH is able to provide alternative sources of clean water for communities in the Jelegong Village area.   Abstrak Sistem pemanenan air hujan (SPAH) merupakan teknologi mengumpulkan dan menampung air hujan untuk sumber air bersih alternatif. Tujuan penelitian ini adalah melakukan perencanaan SPAH mencakup penentuan strategi, analisis kelayakan berdasarkan kualitas dan kuantitas air hujan, dan perencanaan basic engineering design SPAH. Perencanaan dilakukan di Desa Jelegong Kabupaten Bandung, yaitu wilayah dengan kondisi resapan air yang kritis, belum terlayani jaringan perpipaan air bersih, dan hanya menggunakan air tanah dengan ketersediaan yang terbatas sebagai satu-satunya sumber air pada musim kemarau. Data primer dikumpulkan melalui survei lapangan dan sampling kualitas air hujan pada periode awal hujan (September, 2022). Daerah tangkapan air terpilih adalah permukaan atap rumah. Secara kuantitas, dengan 55 rumah yang dilayani, potensi pasokan air hujan (4.318,88 m3/tahun) dapat memenuhi kebutuhan penggunaan air non-minum (2.369,65 m3/tahun) seperti aktivitas mandi dan keperluan WC, dan kegiatan mencuci pakaian. Secara kualitas, parameter warna air hujan belum memenuhi kualitas air bersih berdasarkan Permenkes 32/2017. SPAH komunal diimplementasikan karena lahan terbatas dan tingkat kepadatan penduduk tinggi. Air hujan yang dikumpulkan akan melalui proses desinfeksi dan filtrasi sehingga memenuhi baku mutu air bersih, kemudian disimpan pada ground tank (70 m3) dan roof tank (5 m3) untuk didistribusikan ke setiap rumah. Dengan demikian, SPAH yang direncanakan mampu menyediakan sumber air bersih alternatif bagi masyarakat di wilayah Desa Jelegong.

Abstract

The problem of plastic waste generation is increasingly pressing in Indonesia. Thermal technology offers an alternative solution that is more environmentally friendly in managing plastic waste. This literature study aims to compare pyrolysis and gasification technologies in converting plastic waste into energy. The analysis was carried out by reviewing various relevant studies. The results of the study indicate that both technologies have the potential to reduce plastic waste generation and produce value-added products. Pyrolysis is a thermal decomposition process without oxygen that produces oil, gas, and charcoal. Gasification produces syngas that can be used as fuel. This process requires limited oxygen and produces more diverse emissions. The comparison between pyrolysis and gasification shows that the selection of the right technology depends on several factors, such as the type of plastic, the desired product quality, and environmental considerations. Pyrolysis is more suitable for oil production, while gasification is more flexible in producing various types of gas products. Overall, both pyrolysis and gasification have great potential in managing plastic waste. However, further research is needed to optimize the process and reduce environmental impacts. Thus, thermal technology can be a sustainable solution in overcoming the problem of plastic waste in Indonesia.

Abstract

Domestic wastewater service with a piped system by PDAM Kota Bandung currently has not reached evenly and thoroughly to remote residential areas. In 2008, PDAM collaborated with the Environmental Services Program-United States Agency for International Development (ESP-USAID) built MCK Plus (MCK equipped with a bio-digester septic tank). This research was conducted at RW 07 Tamansari, Lebak Siliwangi Village, Bandung City and was carried out in March-May 2023. The data collected was primary data from observations, questionnaires, and interviews, while secondary data from literature studies. The survey results found that 8 MCK were abandoned and had been used as storage areas (warehouses) as well as chicken coops. For the service of 35 households, the required rectangular septic tank are 3.2 m wide, 9.6 m long, 3.2m high and the volume of the septic tank is 61.5m3. From the calculation results, the biogas produced per day can be used for cooking activities for a maximum of 2 people. Septic tanks as a technology for treating wastewater have a good impact on society if used effectively. To get the maximum potential from implementing a septic tank, it requires not only community participation, but also collaborative government institutions to support this program.
