Abstract
Pelayanan air minum di Kota Surabaya telah mencapai 98,6% dengan total
jaringan pipa distribusi primer adalah sebesar 151.203 meter, pipa distribusi
sekunder adalah 676.850 meter dan pipa distribusi tersier adalah 3.384.783 meter.
Permasalahan yang dihadapi PDAM Kota Surabaya adalah kebocoran pada
jaringan distribusi. Kehilangan air akibat kebocoran jaringan dapat disebabkan
oleh beberapa faktor seperti; usia pipa, panjang pipa, material pipa, lokasi
pemasangan pipa, sambungan pipa, kedalaman pipa, material urugan pipa dan
tekanan air dalam pipa. Rehabilitasi pada jaringan distribusi memerlukan investasi
yang tidak sedikit sementara dana investasi yang dialokasikan terbatas.
Untuk menjawab tantangan tersebut, penelitian ini mengaplikasikan
metode Analytical Hierarchy Process (AHP) untuk menentukan area prioritas
program rehabilitasi dan kriteria penyebab kebocoran yang paling berpengaruh.
Diawali dengan mengklasterkan seluruh area jaringan pipa kemudian dilanjutkan
dengan AHP dan analisis sensitivitas untuk mengetahui kriteria yang paling
sensitif. Hasil yang didapatkan adalah Klaster I merupakan area yang paling
prioritas untuk program rehabilitasi dengan Bobot 41,66%, klaster 2 sebesar
27,91% dan klaster 3 sebesar 28,84%. Sedangkan kriteria penyebab kebocoran
adalah umur dengan bobot tertinggi yaitu 18,8%, material 16,2%, sambungan pipa
15,9%, lokasi pipa 15%, kedalaman pipa 11,5%, material urugan pipa 8,7%,
tekanan air dalam pipa 7,3% dan kondisi tanah sekitar pipa memiliki bobot yang
paling kecil yaitu 6,6%.

Drinking water supply service in Surabaya has reach 98,6% using total 151.203 meter of primary water pipe, 676.850 meters of secondary water pipe and 3.384.783 meters of tertiary water pipe. PDAM Surabaya must deal with leakage problems in water distribution system. Leakage in water distribution system caused by several factors i.e. age, length, material, location, joint, depth, landfill material, and water pressure. Rehabilitation in water distribution system required great amount of investment yet the budget is limited. More efforts should be made to identify priority area and leakage’s criteria so that decision makers can prioritize repair, rehabilitation, or replacement activities. In order to continue consider the criteria for repairing, this research is proposed to utilize MCDM approach. One of the selected methods is Analytical Hierarchy Process (AHP) for prioritizing the rehabilitation pipe area and leakage’s criteria.
First steps is to consider All pipe locations were clustered then continued to Analytical Hierarchy Process. The second steps is sensitivity analysis to determine the most significant criteria. The result is Cluster I is the most priority area to conduct rehabilitation with 41,66% of total score, while Cluster 2 is 27,91% total score and Cluster 3 is 28,84%. Moreover, the most significant Leakage Criteria is age in 18,8%, material in 16,2%, pipe joint in 15,9%, location in 15%, depth in 11,5%, landfill in 8,7%, water pressure in 7,3% and soil condition in 6,6%.
