Judul: Karakteristik habitat banteng (Bos javanicus d'Alton 1832) di Taman Nasional Meru Betiri, Jawa Timur
Abstrak: Banteng (Bos javanicus d'Alton 1832) is one of the large mammals in Meru Betiri National Park (MBNP). IUCN 2008 Data Red List of Threatened Animals listed banteng as endangered species. Banteng is a protected species according to The Government Regulation of Republic of Indonesia No. 7 / 1999. The main problem of banteng in Meru Betiri National Park was invasion banteng to the private plantation area of PT. Perkebunan Bandealit and PT. Perkebunan Sukamade Baru. Therefore, study of banteng habitat characteristics was needed to determine food, water, and cover availability as basis for banteng conservation effort. This research was held in three National Park Management Sections (SPTN), including SPTN W I Sarongan, SPTN W II Ambulu, and SPTN W III Kalibaru. This research was held in July-August 2010. Structure and composition of vegetation studied using line transect method of vegetation analysis. The observation of banteng’s food plants was done through by observation of browsing signs. Measuring of productivity, palatability, and carrying capacity was done by making of plot sampling 1x1 m². Cover characteristics observation was done by identifying of cover types which used by banteng. The data of water sources characteristic was obtained by water resources inventory in each location. Banteng included to the intermediate group between grazer and browser ungulata. The types of banteng’s feed in study sites contained of 25 species, mostly obtained from the plantation area. Productivity of banteng’s feed in Banyuputih Block is 463,92 kg/ha/day for 16 banteng. The highest palatability of banteng’s feed at Banyuputih Block and Sikapal Block is paitan (Paspalum conjugatum). Most of cover used by banteng was tree canopy and bamboo which has the function as a protection from the sun. Most of water sources for drink are the river flow to the estuary. The water sources in location are Sumbersari River, Cawang River, Sanen Kali River and Banyuputih River. The preferable habitat of banteng was Banyuputih Block which contains plantation area and low land rain forest that provide feed, water and cover. Habitat function in TNMB is less than optimal caused by banteng moved to the plantation areal and it rendered wild hunting by local people. To overcome the problem, it is required intensive habitat management for banteng in order to prevent banteng enter the plantation area.

Judul: Pola Penggunaan Habitat Banteng (Bos javanicus d’Alton 1823) di Taman Nasional Alas Purwo
Abstrak: Banteng (Bos javanicus d’Alton, 1823) telah dilindungi sejak tahun 1931 dan berstatus endangered berdasarkan IUCN Red List versi 3.1. Penelitian ini bertujuan untuk menghasilkan data dan informasi mengenai karakteristik habitat, aktivitas, dan wilayah jelajah banteng di TNAP. Setiap tipe habitat memiliki jumlah jenis tumbuhan dan jenis pakan yang berbeda, yakni 40 jenis tumbuhan dan 15 jenis pakan di hutan dataran rendah, 30 jenis tumbuhan dan 23 jenis pakan di hutan tanaman, 18 jenis tumbuhan dan 1 jenis pakan di hutan pantai, 3 jenis tumbuhan di hutan mangrove, serta 27 jenis tumbuhan dan 26 jenis pakan di padang penggembalaan. Berdasarkan uji Chi-Square diperoleh hasil bahwa terdapat hubungan antara aktivitas dengan tipe habitat yang digunakan. Hutan dataran rendah lebih sering dijadikan sebagai tempat berlindung, hutan tanaman lebih sering dijadikan sebagai tempat istirahat dan merumput, hutan pantai dan mangrove lebih sering dijadikan sebagai tempat mengasin, dan padang penggembalaan lebih sering dijadikan sebagai tempat merumput. Berdasarkan hasil pemetaan diperoleh bahwa luas wilayah jelajah banteng di TNAP sebesar ±6,46 km2

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.
