Abstract

This research aims to model residual chlorine in the drinking water distribution system with EPANET 2.2 software in the IPA Aurduri 3 of service area. The problem that occurs is the construction of the Aurduri 3 IPA in 2020 to meet the need for clean water in several areas that are not reached by the Aurduri 1 IPA and 2, especially the Bougenville, Pinang Merah and surrounding areas. Adding chlorine twice, namely at the IPA Aurduri 3 and the booster pump, increases the risk of excess chlorine in the service area and can reduce water quality. Modeling the distribution of residual chlorine in the clean water distribution system can provide a solution in dealing with residual chlorine in drinking water distribution. The results found of 30 points in the clean water network that were below standard and dominated at the service end with residual chlorine ranging between 0-0.4 and after calibration 0.16-0.3. This is due to the age of the water which is influenced by velocity which does not meet the standard by 121 points and causes delays in obtaining residual chlorine at sufficient levels.

Abstract

Timbulan sampah yang dihasilkan oleh institusi pendidikan seperti sekolah, pondok pesantren dan kampus kerap tidak terlihat secara kasat mata namun sebagai lingkungan dengan jumlah siswa yang besar berpotensi menghasilkan sampah yang cukup banyak setiap harinya. Jika tidak dikelola dengan baik, sampah ini dapat menimbulkan pencemaran dan masalah kesehatan. Salah satu solusi yang dapat diterapkan adalah pengolahan sampah terutama sampah berjenis organik menggunakan larva lalat tentara hitam. Kegiatan ini bertujuan untuk memberikan sosialisasi kepada santri pondok pesantren Nurul Iman tentang biokonversi sampah organik berbasis BSF sebagai alternatif pengelolaan yang ramah lingkungan dan bernilai ekonomi. Metode yang digunakan adalah pemaparan materi melalui presentasi dan diskusi interaktif yang menjelaskan manfaat, proses kerja larva dalam mengurai sampah, serta dampaknya terhadap lingkungan. Evaluasi dilakukan melalui pengisian kuesioner sebelum dan sesudah penyuluhan, yang dianalisis secara deskriptif dan menggunakan perhitungan gain score untuk menilai efektivitas intervensi edukatif. Hasil menunjukkan peningkatan pengetahuan pada sebagian besar indikator, terutama pada pemahaman tentang manfaat ekonomi dan ekologis biokonversi. Meskipun sesi praktik tidak dapat dilaksanakan karena kendala teknis, peserta menunjukkan minat tinggi dan peningkatan pemahaman yang signifikan pada aspek konseptual. Kegiatan ini dinilai efektif dalam membentuk kesadaran ekologis awal serta membuka peluang untuk pengembangan program lanjutan berbasis pesantren yang berorientasi pada pengelolaan limbah berkelanjutan dan pemberdayaan ekonomi lingkungan.

Abstract

The supply of safe drinking water in the developing world, particularly in Indonesia, has remained one of the major challenges. Millions are still without access to clean water, which inflicts public health and has negative implications for socioeconomic development. This paper elaborates on the multifaceted challenges facing the drinking water supply in Indonesian cities, from inconsistent policies and lack of autonomy for Water Agencies to aging infrastructure, unreliable power supply, and inadequate investment. Brief case studies from Jakarta, Surabaya, and Padang plainly bring out the specificity of issues in various cities. The paper suggests that solutions can lie in policy reform, empowering the water agencies, fighting corruption, greater investment in infrastructure, making the most of pricing and cost recovery, and strategic engagement with the private sector. Unless these are addressed, such challenges will persist in hindering the progress of Indonesia toward the universal access goal for all urban residents to sufficient, safe, reliable, and affordable drinking water
