Judul: Distribusi Kebisingan Pada Perahu Katir Penangkap Ikan Di Palabuhanratu, Sukabumi, Jawa Barat (Studi Kasus Pada Km Seuri Mulya 1)
Abstrak: KM Seuri Mulya 1 merupakan kapal penangkap ikan yang diklasifikasikan ke dalam golongan motor tempel di Indonesia. Tujuan penelitian ini adalah menentukan tingkat kebisingan di perahu katir, dan menentukan Nilai Ambang Batas (NAB) yang sesuai dengan Permenakertrans No.13/ MEN/X/2011 tentang NAB Faktor Fisika dan Faktor kimia di Tempat Kerja. Berdasarkan hasil penelitian, KM Seuri Mulya 1 memiliki sumber kebisingan berasal dari mesin motor yang menghasilkan kebisingan selama 11,5 jam. Nilai kisaran tingkat kebisingan di KM Seuri Mulya 1 adalah sebagai berikut: menuju ke fishing ground: 62,57–95,43 dB; setting: 52,53–80,67 dB, dan kembali ke fishing base: 65,50–98,33 dB. Kebisingan di kapal terjadi pada aktivitas menuju ke fishing ground, saat setting, dan saat kembali ke fishing base berasal pada posisi bagian belakang perahu.

Judul: Tingkat Kebisingan pada Kapal Penangkap Ikan (Studi kasus pada Modern Boat Liftnet KM Omega Jaya di Pulau Ampel Serang, Banten)
Abstrak: KM Omega Jaya is a fishing vessel which is classified as Modern Boat Liftnet. The purposes of this research were to identify the sources of noise on vessel in fishing gear, to describe the pattern of noise distribution on vessel, and to define TLV (Threshold Limit Values) comply with Kep-51/MEN/1999. The result showed that KM Omega Jaya had two sources of noise, main engine and generator which produced noise for four hours and six hours respectively. The average of noise level which was produced by main engine was 91,19 dB(A), while generator was 93,85 dB(A). The pattern of noise distribution from two sources showed that the noise was divided into six colour areas; red (98dB-106dB), orange (94dB-98dB), yellow (90dB-94dB), green (84dB-90dB), blue (74dB-84dB), and purple (70dB-74dB). The characteristic of noise pattern which was produced by two sources are similar. Based on Decree of the Minister of Labour No. Kep-51/MEN/1999, the recommended TLV for noise on KM Omega Jaya was 84,25 dB. However, there were only 10,34% (when the main engine turned on) and 9,9% (when the generator turned on) of deck area which had safe noise level.

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.
