Permasalahan penelitian ini adalah masih terdapat indikasi kendala pada beberapa aspek pelayanan infrastruktur jaringan air bersih di Kecamatan Meuraxa Kota Banda Aceh yang memerlukan evaluasi, terutama terkait kontinuitas distribusi, kualitas layanan, dan pemerataan pelayanan. Penelitian ini bertujuan untuk mengevaluasi kinerja hidraulis jaringan pipa distribusi air bersih PERUMDAM Tirta Daroy, serta menganalisis korelasinya terhadap tingkat kepuasan pelanggan. Metode penelitian mengintegrasikan simulasi numerik program EPANET 2.2 dengan analisis deskriptif kuantitatif menggunakan kuesioner skala Likert kepada 100 pelanggan dan 10 staf teknis. Hasil simulasi menunjukkan sisa tekan berada pada kondisi optimal (4,064–6,254 bar) sesuai Permen PU No. 18/PRT/M/2007. Namun, keandalan tekanan tidak selaras dengan parameter kecepatan aliran. Stagnasi aliran kritis terdeteksi pada sejumlah pipa dengan kecepatan hanya 0,01 m/det, berada di bawah ambang batas minimal self-cleansing velocity (0,3 m/det) akibat fenomena dimensi pipa yang terlalu besar. Selain itu, terjadi lonjakan kehilangan tekanan (headloss) ekstrem sebesar 32,99 m/km pada jam puncak pagi hari. Analisis kepuasan masyarakat menghasilkan nilai Tingkat Capaian Responden (TCR) sebesar 76,79% (kategori puas). Meski demikian, parameter keadilan distribusi debit memperoleh skor terendah (TCR 73,40%). Penilaian subjek tersebut terkonfirmasi secara objektif melalui simulasi yang mendeteksi ketimpangan pasokan masif antara area hulu (43,39 l/det) dan area hilir terjauh (0,05 l/det).

The problem of this research is that there are still indications of obstacles in several aspects of clean water network infrastructure services in Meuraxa District, Banda Aceh City that require evaluation, especially related to distribution continuity, service quality, and service equity. This study aims to evaluate the hydraulic performance of the clean water distribution pipe network of PERUMDAM Tirta Daroy, and analyze its correlation with the level of customer satisfaction. The research methodology integrates numerical simulation using EPANET 2.2 software with quantitative descriptive analysis utilizing Likert-scale questionnaires distributed to 100 customers and 10 technical staff members. The simulation results indicate that the residual pressure remains optimal, ranging from 4.064 to 6.254 bar, which complies with the Ministry of Public Works Regulation No. 18/PRT/M/2007. However, this pressure reliability does not align with the flow velocity parameters. Critical flow stagnation was detected in several pipes with velocities of only 0.01 m/s, falling below the minimum self-cleansing velocity threshold of 0.3 m/s due to pipe oversizing. Furthermore, an extreme headloss spike of 32.99 m/km occurred during morning peak hours. The customer satisfaction analysis yielded a Respondent Achievement Score (TCR) of 76.79% (satisfied category). Nonetheless, the equity of flow distribution parameter received the lowest score (TCR 73.40%). This subjective assessment was objectively validated by the simulation, which revealed a massive supply disparity between the upstream area (43.39 l/s) and the farthest downstream area (0.05 l/s).
