Abstract
Strategi manajemen kebocoran jaringan distribusi air bersih terdiri dari empat faktor penting, yang meliputi manajemen tekanan, waktu perbaikan, pengendalian kebocoran aktif, dan manajemen aset. Faktor-faktor ini mempengaruhi bagaimana kebocoran dapat dikelola dan dengan demikian volume dan nilai kebocoran secara ekonomi, dalam sebuah jaringan distribusi air bersih dapat diketahui. Volume kehilangan fisik tahunan pada sistem distribusi air bersih memiliki kecenderungan yang meningkat seiring dengan meningkatnya area layanan jaringan distribusi. Tingkat kenaikan tersebut dapat dihambat dengan menerapkan kombinasi yang tepat di antara keempat faktor dalam strategi pengelolaan kebocoran yang efektif. Dalam penelitian ini, faktor-faktor yang mempengaruhi kehilangan air dalam sistem distribusi air di Kota Malang dianalisis dengan berfokus pada aspek fisik dan operasional jaringan. Dalam praktek operasional dan pemeliharaan jaringan, lazimnya otorita penyedia air bersih membagi divisi operasional dan pemeliharaan ke dalam beberapa sub divisi berdasarkan batas wilayah zona layanan. Sementara di sisi lain, tidak semua zona layanan memerlukan prioritas yang sama dalam penanganan kebocoran. Dengan demikian, kajian yang melibatkan parameter spasial dalam pengelolaan kebocoran merupakan kebutuhan otorita penyedia air bersih saat ini. Data dalam penelitian ini meliputi data spasial serta data kuantitatif parameter operasional dan fisik jaringan. Distribusi poisson dalam proses spasial dipilih sebagai pendekatan sebaran titik kebocoran. Dari analisis didapatkan bahwa pola persebaran kebocoran pipa di Kota Malang termasuk dalam kriteria inhomogeneous poisson process dengan adanya dua jenis intensitas persebaran lokasi kebocoran. Berdasarkan hasil estimasi parameter didapatkan bahwa pada wilayah intensitas kebocoran tinggi dipengaruhi oleh waktu perbaikan, diameter pipa, rasio panjang pipa, rasio debit, dan rasio deteriorisasi pipa namun tidak dipengaruhi oleh rasio kebutuhan tekanan hidraulik. Sedangkan pada intensitas kebocoran rendah dipengaruhi oleh diameter pipa, rasio panjang pipa, rasio debit, rasio deteriorisasi pipa, dan rasio kebutuhan energi hidraulik namun tidak dipengaruhi oleh waktu perbaikan.

There are four pillars in the leakage management strategy for water distribution networks which include pressure management, speed of recovery, active leakage control, and asset management. These factors influence how leakage can be managed and thus the volume and value of leakage economically, in a water distribution network can be known. The annual volume of physical losses in the water distribution system tends to increase along with the increase in the distribution network service area. The rate of increase can be inhibited by applying the right combination of the four factors in an effective leak management strategy. In this study, the factors that influence physical water loss in the water distribution system in Malang City are analyzed by focusing on the physical and operational aspects of the network. In network operations and maintenance practices, it is common for water supply providers to divide operational and maintenance divisions into subdivisions based on service zone boundaries. While on the other hand, not all service zones require the same priority in handling leakage. Thus, studies involving spatial parameters in managing leakage are the current needs of the water supply provider authority. The data in this study include spatial data as well as quantitative data on operational and physical network parameters. The Poisson distribution in the spatial process is chosen as the leakage point distribution approximation. From the analysis, it was found that the distribution pattern of pipeline leakage in Malang City was included in the inhomogeneous Poisson process criteria, with the existence of two types of intensity. Based on the results of parameter estimation, it is found that in areas of high leakage intensity is affected by speed of recovery, pipe diameter, pipe length ratio, supply discharge ratio, and pipe deterioration ratio but is not affected by the energy demand ratio. While the low leakage intensity is influenced by pipe diameter, pipe length ratio, supply discharge ratio, pipe deterioration ratio, and the energy demand ratio but is not affected by the speed of recovery.
