Judul: Estimation of Economic Loss due to the Pollution  of Paper Industry Waste (Case study: Tengkurak Village, Tirtayasa Sub district,  Serang, Banten)
Abstrak: Industri kertas merupakan industri andalan baik pasar domestik maupun pasar ekspor dimana industri kertas dapat memberikan kontrubusi PDB. Namun, industri kertas dapat memberikan dampak negatif apabila limbah industri tidak bisa dikelola dengan baik. Penelitian ini bertujuan untuk mengkaji eksternalitas negatif akibat limbah industri kertas dengan menggunakan analisis deskriptif, mengestimasi besarnya biaya eksternal yang ditanggung masyarakat dengan menggunakan cost of illness, replacement cost, dan loss of earnings, mengestimasi besarnya nilai kompensasi yang bersedia diterima masyarakat dengan menggunakan Contingent Valuation Method, dan menganalisis faktor faktor yang memengaruhi besarnya kompensasi masyarakat dengan menggunakan analisis regresi linier berganda. Hasil penelitian menunjukkan bahwa eksternalitas negatif yang dirasakan masyarakat adalah penurunan kualitas air sungai dan kualitas air tanah. Rata-rata biaya eksternal yang harus ditanggung responden sebesar Rp 191 341 182.6/kepala keluarga/tahun. Dugaan nilai rataan willingness to accept responden sebesar Rp 3 645 454.2/kepala keluarga/tahun. Faktor-faktor yang mempengaruhi besarnya nilai willingness to accept responden yaitu usia, pendidikan, pendapatan, jarak dengan sungai, jumlah tanggungan, lama tinggal, total kerugian ekonomi, persepsi kualitas air, dan dummy jenis kelamin.

Judul: Estimasi Nilai Kerugian Masyarakat Akibat Pencemaran Air Tanah di Sekitar Kawasan Industri (Studi Kasus Industri Keramik di Kelurahan Nanggewer, Kabupaten Bogor)
Abstrak: One of the activities of economy, like an industrial activity may reduce the level of environmental quality. The study of the estimation of both external cost and public compensation (WTA), the effects toward environment caused by industrial activities is needed to achieve sustainable development. The objectives of this study are to identify the negative externality effect of the industry activity, to estimate economic losses and WTA value caused by industrial activities, and to identify the factors that influence WTA value. This paper presents explores the descriptive analysis, valuation of environmental economics, and application of Contingent Valuation Methods (CVM). The result shows that the economic loss of each household per month is IDR 125,716.67 and the average values of household’s WTA per month is IDR 497,674.42. There are seven factors those influence WTA value significantly such as age, gender, income, economic loss caused by replacement cost, education level, the distance between houses and industry area, and economic loss caused by medical cost.

Judul: Pengoptimuman Alignment Struktur Protein Menggunakan Clique Maksimum
Abstrak: An alignment of protein structures describes the relationship of two types of proteins similarity function. The problems of the protein structure alignments can be identified through the problems of the Contact Map Overlap (CMO). The problems of CMO can be solved by finding a maximum clique in a graph, where vertices and edges represent the amino acids and contacts between any two amino acids respectively. In this paper, the problem of finding maximum cliques is using two main steps, the arranging vertices and edges based on the special properties of the graph and preprocessing vertices. Implementation of the model is done by using the structure of a hypothetical protein.
