Masalah pemanfaatan air bawah tanah bagi Perusahaan Air Minum dalam kemasan : studi kasus di PT Tang Mas Cidahu Sukabumi

Abstract

Water is a class of renewable natural resources. The main source of water is the rain that will always come during its season along the year. The water flows and moves (on the ground and underground) and then will stay at a retention (storage) area. There are two kinds of the retention that are i) natural retention (such as concave areas, lake, and low places) and ii) artificial retention (such as saving water, well, and basin). The presence of the river basin in a region will affect the availability of water resources. A region which has river basin could use ground water resources to fulfill the water requirements for household, agriculture, industries, tourism, and electric power station sectors. A manufacturing of drinking water in packing (AMDK) is normally built around a river basin area so that it can use the resource of water from the spring. But a problem would arise whenever the manufacture decide to increase the production capacity. This research addressed the problem of determining an optimal composition on water resources for AMDK manufacturing in order to minimizing the total cost. Each water resource alternative has different cost characteristics. The cost can be classified to fixed and variable cost. This problem is modeled as an integer linear programming problem and solved using branch and bound method via LINGO 8.0 software. This model is implemented at PT Tang Mas Cidahu in Kampung Bojong Pari Desa Jaya Bakti Kabupaten Sukabumi, West Java.
