Abstract. The Bandarudara Internasional Jawa Barat (BIJB) and Kertajati Aerocity are under construction and expected to be a center of economic activity supported by potential of natural resources and agriculture. They later will act as a driver of economic growth in West Java, especially for surrounding area such as Kertajati, Jatitujuh and Ligung Sub-districts. As an affect of the the development of BIJB and Kertajati Aerocity, the water demand of surrounding area will increase. Therefore an analysis of water demand and availability is needed. This research supports by analyzing the water balance, water demand, and also water allocation using WEAP (Water Evaluation and Planing) software tool. Water balance of Cimanuk-Tomo, Cimanuk-Monjot, and Cilutung-Dam Kamun river are analyzed, water demand of the three sub-districts are also projected and become the inputs of the water allocation model. The result of WEAP model simulation shows that the Cimanuk River can meet the water demand of the three sub-districts until 2040.
1 Background and Kertajati Aerocity. Especially in the regions service areas in Kertajati Subdistrict (outside Region Aerocity), PT Bandarudara Internasional Jawa Barat (PT BJIB) Jatitujuh, and Ligung. Therefore it is necessary to analyze responsible for operating West Jawa Internasional Airport the water demand and identify the water resources to meet and developing Aerocity. In order to encourage the the total water demand, as well as the planning of water development of the Ciayumajakuning (Cirebon- resources management in 3 (three) sub districts to support Indramayu-Majalengka-Kuningan) region as well as the the development and growth of BIJB and Kertajati increase of economic growth and public service especially Aerocity. With well managed water resources, water in the field of transportation, set in 2010 the development demand (domestic needs) can be fulfilled and sustainable and growth of the international airport of West Java and water resources management can support infrastructure Kertajati Aerocity. BJIB’s accessibility is guaranted by development and growth. This research using Water having both highway and railway connected Bandung, Evaluation and Planning (WEAP) system for water Kertajati, dan Cirebon. BJIB plans to ensure sufficient resources allocation, which is suitable for incorporates a capacity to meet future demand in air travel wich can demand priority and supply preference approach to drive handle 5 million passanger per year. the allocation of water from water supply. WEAP model Development and growth of BIJB and Kertajati using linear program algorithm, iterated to optimize Aerocity is implemented by developing Kertajati Urban demand and supply priorities. WEAP model has been Area which is integrated with the development and used in several water related researches across the world, growth of airport. The development of Kertajati Urban for example to determine the impact of a number of Area certainly affect Kertajati Area itself and also around. possible Development scenarios in Lake Tana Catchment, Among them is the Center for Local Activities Kertajati Ethiopia (Alemayehu et al. 2010) [7]. It is also used in with service functions as a commercial area and services, Western Africa to study the impacts of hydropower an integrated industrial area BIJB, the development of production due to land use and land cover changer under maritime Aerocity, Central Services Area Jatitujuh with climate changes (Obahoundje et al. 2017) [9]. service functions as housing development, services, industry, and agriculture Serving sub-district or village- level activities, and Central Services Area Ligung with 2 Location of the study area service function as security area, industrial development, The BJIB and Kertajati Aerocity is located in Majalengka social service, and agriculture serving sub district or some district, while the focus of this research are Kertajati, village. Therefore it is necessary to plan development and Jatitujuh and Ligung districts as shown in Figure 1. growth of three sub districts to support development and Majalengka is among the big districts such as Indramayu, growth of BIJB and Kertajati Aerocity Regions. Cirebon, Kuningan, Ciamis and Tasikmalaya. In urban Water demand increases along with population growth in Majalengka Regency and will continue to increase in line with the development and growth of BIJB
