Abstract

The Sub Watershed of Cibabat is one of the rivers included in the Upstream Citarum River, in Cimahi City. This industrial sector which consists of 36 different industries is among the highest contributors of pollution load. Aim: This study analyzed the pollutant loads entering the Cibabat River in existing conditions and projections from the industrial sector. Methodology and Results:  The pollutant loads, emitted from the industrial sector was used to calculate the discharged data, concentration, number of employees and products, as well as emission factors (EF). In 2018, the industrial sector pollution load was 3,518.82 kg/day TSS, 8,231.83 kg/day BOD and 14,467.68 kg/day COD. However, it increased to 3,885.06 kg/day TSS, 9,088.61 kg/day BOD and 15,973.48 kg/day COD during this project year. Conclusion, significance and impact study: The pollution loads on Cibabat River emitted from the industrial sector, which increases yearly by 2% was be reduced by developing wastewater treatment communal for industries.

Abstract

Pada satu dekade terakhir, Zero Waste muncul sebagai satu dari konsep pendekatan pengelolaan persampahan yang dianggap menjanjikan. Berbagai pihak memperkenalkan Zero Waste sebagai cara baru pengelolaan sampah, yang berupaya mengurangi sekecil mungkin timbulan sampah yang dibuang ke Tempat Pembuangan Akhir. Untuk mengukur keberhasilan penerapan Zero Waste tersebut, beberapa indeks terkait Zero Waste Management telah dikembangkan. Paper ini bertujuan untuk memberikan kontribusi yang signifikan kepada pengembangan Zero Waste Management Index di masa depan melalui sebuah tinjauan terhadap beberapa Zero Waste Management Index yang telah ada dan peluang penerapannya di Jawa Barat. Studi ini menunjukkan bahwa indikator-indikator yang dikembangkan dalam Zero Waste Management Index cenderung parsial, hanya mempertimbangkan aspek lingkungan, dan tidak mengintegrasikan pengertian pengelolaan dalam arti luas (yang juga mencakup aspek ekonomi, sosial, finansial, ataupun regulasi dan kebijakan dari sistem pengelolaan persampahan). Lebih jauh, meskipun indeks tersebut berhasil diaplikasikan dalam konteks penelitian yang bersangkutan, namun seringkali tidak dapat digunakan di wilayah atau negara lainnya. Oleh karenanya, studi ini merekomendasikan untuk mengembangkan Zero Waste Management Index yang sesuai dengan kondisi lokal atau regional tertentu dan mengatasi kelemahan-kelemahan dari indeks yang telah ada

Abstract

Cimahi City is one of the cities that participated in the Accelerated Habitation Sanitation Development Program in 2011. This was done because the Cimahi City Government realized that the sanitation conditions in Cimahi City were still of concern. In 2015, the coverage of drainage system services reached 89.87%. Meanwhile, inundation and flood area in 2018 in Cimahi City reached 36.4 hectares or equal to 0.76% of the total area of Cimahi City. Inundation and floods that occur resulting in displaced residents as well as financial losses. Based on the following problems, this study was conducted to calculate the level of risk in each urban village in Cimahi City. The level of risk is expressed in scores ranging from 1 - 4. A score of 1 means very low risk, a score of 2 means low risk, a score of 3 means high risk, and a score of 4 means very high risk. Determination of risk scores involves exposure factors and impact factors Exposure factors consist of inundation area percentage, sanitation risk index (IRS) score based on EHRA, and OPD perceptions. While the impact factors consist of population, population density, poverty rate, and urban / rural function.

Abstract

Kawasan Perkotaan Betun terletak di Kecamatan Malaka Tengah, Kabupaten Malaka, Provinsi Nusa Tenggara timur yang dihuni oleh 23.058 jiwa pada tahun 2021 belum memiliki jaringan perpipaan distribusi air minum. Sebanyak 57,87% penduduk masih menggunakan sumber air minum bukan jaringan perpipaan tidak terlindungi. Oleh karena itu dibutuhkan perencanaan sistem jaringan perpipaan air minum agar masyarakat terlayani oleh sumber air minum yang terlindungi dengan pemanfaatan air baku dari 7 Mata Air menggunakan bangunan penyadap mata air dan debit minimum sebesar 50 liter/detik yang akan ditampung di reservoir dan di distribusikan kepada masyarakat melalui Jaringan Perpipaan. Kebutuhan air minum dihitung berdasarkan proyeksi jumlah penduduk serta fasilitas sosial ekonomi, dengan periode perencanaan selama 20 tahun sampai tahun 2042. Total kebutuhan air minum rata-rata yang di proyeksikan pada tahun 2042 adalah 21,12 l/dtk. Perencanaan ini, menggunakan 3 buah alternatif jalur yang selanjutnya dianalisis jalur yang paling sesuai dengan metode dan kriteria teknis Permen PUPR 27/2016. Metode yang dianalisis adalah Pugh Matrix dan Weighted Ranking Technique (WRT). Pipa yang digunakan dalam perencanaan yaitu Polyvinyl Chloride tipe AW (untuk aliran bertekanan) dengan variasi diameter pipa sebesar 32 mm sampai 267 mm. Estimasi Rancangan Anggaran Biaya (RAB) yang diperlukan sebesar Rp10.416.950.133.
