Judul: Penilaian Ekonomi Dampak Kebisingan Akibat Aktivitas Penerbangan (Studi Kasus: Bandar Udara Halim Perdanakusuma).
Abstrak: Perubahan status Bandar Udara Militer Halim Perdanakusuma menjadi bandar udara komersil memberikan eksternalitas positif dan negatif bagi masyarakat yang bermukim di sekitar kawasan bandar udara. Adanya eksternalitas positif perubahan status bandar udara ini membuat banyak masyarakat memilih tinggal di sekitar kawaan bandar udara dan mengabaikan eksternalitas negatif yang timbul dari penambahan slot penerbangan di Bandar Udara Halim Perdanakusuma. Masyarakat cenderung pasrah dan mengganggap kebisingan adalah resiko yang harus ditanggung karena memilih tinggal di sekitar kawasan bandar udara. Padahal kebisingan adalah salah satu bahan pencemar dan memiliki dampak atas pencemaran tersebut. Oleh karena itu, penelitian ini bertujuan untuk (1) mengidentifikasi dampak negatif yang dirasakan masyarakat dari kebisingan akibat aktivitas penerbangan di Bandar Udara Halim Perdanakusuma, (2) mengestimasi penilaian masyarakat terhadap kebisingan akibat aktivitas penerbangan, (3) mengkaji faktor-faktor yang mempengaruhi besar penilaian masyarakat terhadap kebisingan akibat aktivitas penerbangan, dan (4) merumuskan rekomendasi alternatif kebijakan yang sebaiknya diterapkan untuk mengatasi permasalahan ini. Hasil analisis menunjukkan bahwa masyarakat mengalami berbagai gangguan psikologis dan fisiologis akibat paparan kebisingan aktivitas penerbangan di Bandar Udara Halim Perdanakusuma. Dugaan nilai rata-rata Willingness to Pay (WTP) seluruh responden adalah sebesar Rp18.125 per bulan per KK. Faktor yang secara signifikan berpengaruh terhadap besar WTP responden antara lain pendapatan, lama pendidikan, status kependudukan, status rumah, getaran yang dirasakan, waktu lama tinggal, jenis kelamin, dan kenyaman responden. Pengendalian kebisingan yang dinilai paling baik untuk mengendalikan kebisingan di Bandar Udara Halim Perdanakusuma adalah dengan pembuatan rekayasa hambatan berupa pagar vegetasi.

Judul: Pemetaan Kebisingan dan Penilaian Masyarakat Terhadap Kebisingan Banda r Udara (Studi Kasus Bandar Udara Sultan Syarif Kasim II Pekanbaru Riau)
Abstrak: Increasing in plane movement and expansion of area to hold bigger plane movement will cause problem to the environment, such as: increasing in noise emision (noises). The objective of this research were to mapping noise zone, analyze influence factor of society perception to noise, analyze influence factor of society willingness to stay or willingness to accept around Sultan Syarif Kasim II Airport Method used in this research were survey and noise measurement. The result of noisy area mapping to zone 1 was 16,251,665 m2, to zone 2 was 4,732,308 m2 and zone 3 was 2,434,037 m2. The factor that influencing society perception to noise were job, length of time , proverty rights, distance and noisy area. The factor influencing level of society willingness to stay arround Sultan Syarif Kasim II Airport were length of time, proverty values and proverty rights. Willingnes to accept society around Sultan Syarif Kasim II Airport were influeced by education, job, proverty rights, distance and noisy area.

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.
