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: Mitochondrial DNA Gene Organization and Phylogenetic Relationship of Naja siamensis
Abstrak: Naja siamensis is one of Asiatic cobra in the Family of Elapidae, known as a cryptic snake. It has many morphological variations that lead to misidentification. Misidentification can cause the wrong concept in developing antivenom types due to high snakebite cases occur in Thailand. Thus, an accurate species identification using a molecular approach is crucially required. Mitochondrial DNA has been used widely in snake molecular studies. These studies were aimed to determine the arrangement of the N. siamensis partial mitochondrial genes using reptile-oriented primers and to reveal the phylogenetic relationship among other species of Asian cobra. DNA extraction was carried out based on the standard DNA salting-out protocol and was conducted by bioinformatics analysis using BLASTn and MEGA 6 software. Gene annotation was performed against N. kaouthia complete genome. A total of 3121 bp of N. siamensis mtDNA genes were sequenced consisting of partial of six regions: 16S rRNA, ND1, tRNA-Ile, CRII region, tRNA-Leu, tRNA-Gln, and COI genes. The mtDNA gene organization of N. siamensis was predicted to has a similar pattern with the common Elapidae mtDNA gene organization. This study showed that there is a monophyletic form in Naja genus and N. kaouthia is the closest species with N. siamensis based on partial 16S rRNA and ND1 gene.
