Judul: Commercialization  and  privatization impact  by pt. Amerta indah otsuka on water resources from islamic shariah perspective (case kutajaya village, Sukabumi)
Abstrak: Air adalah kebutuhan dasar manusia untuk memenuhi kebutuhan sehari-hari. Berdasarkan penjelasan berdasarkan Al-Quran, air digolongkan kepada harta yang haknya dimiliki oleh setiap umat karena urgensi kebutuhannya. Komoditas air memiliki manfaat, tetapi kepemilikannya kerap menimbulkan sengketa pemilik hak antara masyarakat dan instansi, seperti PT. Amerta Indah Otsuka sebagai perusahaan air minum dalam kemasan (AMDK) dari minuman isotonik Pocari Sweat yang menggunakan air sebagai bahan baku produksi. Air yang digunakan untuk produksi berasal dari Desa Kutajaya yang sumber air tanahnya juga dimanfaatkan oleh masyarakat sekitar. Kondisi ini menimbulkan permasalahan hak kepemilikan air bersih bagi warga karena sumber air bersih diprivatisasi oleh perusahaan. Warga RT 07 RW 04 yang bersebelahan langsung dengan perusahaan mengalami kekeringan air dan kekeruhan air pada sebagian responden. Penelitian ini menganalisis persepsi responden sebelum dan sesudah adanya PT. Amerta Indah Otsuka di Desa Kutajaya, nilai Willingness To Pay dan Willingness To Accept beserta faktor-faktor yang memengaruhi dan titik perpotongannya, dan solusi air bersih menggunakan analytical hierarchy process (AHP) serta pandangan maqashid syariah Islam ditinjau dari dua kondisi, yaitu bila maqashid syariah tidak ditegakan dan bila maqashid syariah ditegakan. Hasil analisis menunjukkan masyarakat menginginkan kompensasi atas hak air bersih yang hilang dengan aliran air bersih oleh PT. Amerta Indah Otsuka., Water is one of the basic human daily needs. Islam reviews on its urgency that water is categorized as a property that every human being has rights on its ownership. Water as a commodity has many benefits, however the ownership often leads to disputes between residents and the private agencies, such as bottled water company. PT. Amerta Indah Otsuka that is known for its isotonic drink, Pocari Sweat. The company uses water as one of the raw material of its production. The water used for the production is obtained from the village of Kutajaya as ground water that is also utilized by iii the surrounding residents. This condition raises ownership issues on water as a source of clean water that is privatized by the company. Resident of RT 07 RW 04 is located directly next to the water company drought water. This study analyzes the perceptions of the respondents on impacts before and after PT. Amerta Indah Otsuka started its production in Kutajaya. The willingness to pay (WTP) and willingness to accept (WTA) is also analyzed. And not to forget alternative solution by analytical hierarchy process (AHP). Islamic law is viewed by maqashid sharia. As result of the analysis, it is known that respondents desire compensation for the right of their clean water because of the lack of access to clean water from PT. Amerta Indah Otsuka. Therefore purchasing back clean water from the company (BELI) is one of the alernative solution.

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

Judul: Penyusunan Overlap Graph menggunakan Suffix Tree pada DNA Sequence
Abstrak: The DNA sequence assembly is very important in genome analysis. This step aims to reconstruct contigous DNA fragment (contigs) from short fragment by concatenating fragments based on the overlap region among them. This method employs overlap graph for solving the problems. In this graph, nodes represent fragments and edges represent overlap. This research developed a software for constructing overlap graph using suffix tree. The evaluation was conducted by measuring the number of nodes, number of edges, and the execution time in many values of minimum overlap. The minimum overlap is defined as the minimum length of substring which is considered as the overlap region between two fragments. The evaluation results showed that the number of nodes, the number of edges, and the execution time were increased with the decreasing of the minimum overlap value.
