Introduction

Perencanaan jaringan pipa distribusi air bersih di desa singamerta pdam kabupaten banjarnegara dengan simulasi epanet 2.0. Rencanakan jaringan pipa air bersih Desa Singamerta, Banjarnegara. Simulasi Epanet 2.0 analisis hidrolis untuk penuhi kebutuhan air & tingkatkan cakupan layanan PDAM.

Abstract

PDAM Kabupaten Banjarnegara pada tahun 2019 baru mampu mencapai 14,12% cakupan pelayanan dari total 923.192 populasi. Sehingga untuk meningkatkan pelayanan penulis akan merencanakan jaringan pipa distribusi air bersih dengan menghitung proyeksi penduduk sampai 5 tahun kedepan untuk mengetahui kebutuhan air, merencanakan jaringan pipa distrbusi beserta analisa sistem hidrolis hasil perencanaan. Perhitungan proyeksi penduduk dengan beberapa metode dilakukan dari data sekunder yang didapat dari BPS Banjarnegara untuk dapat mengetahui kebutuhan air di setiap jaringan. Teknik observasi, studi literatur, praktik kerja lapangan, dan wawancara dianalisis menggunakan program Epanet 2.0 sebagai simulator rencana jaringan pipa distribusi. Simulasi program Epanet 2.0 digunakan untuk menganalisis sistem hidrolis pada suatu jaringan. Hasil dari simulasi program Epanet 2.0 pada perencanaan jaringan pipa distribusi air bersih di Desa Singamerta, menghasilkan : tekanan tertinggi pada jam puncak pada node29 yaitu 47,71 mka, dan tekanan terendah pada node35 yaitu 28,98 mka, sehingga tekanan telah memenuhi kriteria yaitu 10 mka. Untuk kecepatan aliran terdapat beberapa pipa yang tidak memenuhi kriteria (0,3-3,0 m/s) dengan kecepatan terendah pada Pipa45 dengan kecepatan hanya mencapai 0,03 m/s.

Review

This paper presents a timely and highly relevant study focusing on the planning of a clean water distribution network in Singamerta Village, Banjarnegara Regency, Indonesia. Addressing the critically low water service coverage by PDAM Banjarnegara, the research aims to significantly improve access to clean water for the local population. The methodology is robust, involving population projections for future water demand over a five-year horizon, followed by the design and hydraulic analysis of a proposed distribution network. The integration of various data sources, including BPS Banjarnegara data, observation, literature review, field work, and interviews, underpins a comprehensive approach, which is then simulated using the widely recognized Epanet 2.0 software. The application of Epanet 2.0 allowed for a detailed hydraulic analysis, yielding important insights into the proposed network's performance. The simulation results indicate that the system generally meets the pressure criteria, with the highest pressure recorded at Node 29 (47.71 mka) and the lowest at Node 35 (28.98 mka), both comfortably above the minimum acceptable threshold of 10 mka. However, a significant finding highlighted is the issue of flow velocity. While the pressure requirements are met, several pipes fail to satisfy the recommended velocity criteria (0.3-3.0 m/s), with Pipa 45 notably registering an extremely low velocity of merely 0.03 m/s. This discrepancy points to potential inefficiencies or design flaws within specific sections of the proposed network. While the study successfully identifies a feasible network design that largely addresses pressure requirements, the critical issue of low flow velocity in certain pipes warrants further investigation and optimization. Future iterations of this design should focus on re-evaluating pipe diameters, network topology, or pump placement in sections where flow velocities are suboptimal to ensure efficient water delivery and prevent potential issues like sedimentation. The paper serves as a valuable preliminary study for PDAM Banjarnegara, providing a strong foundation for improving water access. To further enhance its impact, considering economic feasibility, capital expenditure, and operational costs associated with the proposed network, especially regarding solutions for the low-velocity pipes, would be beneficial for practical implementation. Overall, this research provides a crucial step towards expanding clean water services in the region.
