Judul: Evaluasi Kenyamanan Lingkungan Fisik Kerja pada Ruang Kuliah dan Laboratorium di Fakultas Teknologi Pertanian, Institut Pertanian Bogor
Abstrak: Kualitas lingkungan kerja fisik seperti pencahayaan, suhu dan kelembaban, dan tingkat kebisingan di Fakultas Teknologi Pertanian (Fateta), belum diketahui kesesuaiannya dengan standar yang berlaku. Tujuan dari penelitian ini adalah untuk mengetahui nilai parameter kenyamanan lingkungan fisik kerja dan menentukan ruang kuliah dan laboratorium di Fateta yang memenuhi standar KEP-48/MENLH/11/1996 dan SNI 03-6572-2001 serta analisis suhu berdasarkan grafik psikrometri. Tingkat kebisingan 16 jam tertinggi, suhu udara rata-rata tertinggi, dan intensitas pencahayaan rata-rata tertinggi berada di laboratorium Kimia Pangan dengan nilai berturut-turut 63.2 dB (A), 29°C dan 1076 lux. Kelembaban udara relatif rata-rata tertinggi berada di RK PAU 102B dengan nilai 84.1%. Berdasarkan parameter suhu dan tingkat kebisingan yang terukur, kenyamanan sebagian besar ruang kuliah dan laboratorium sesuai dengan standar yang berlaku. Namun kelembaban udara dan intensitas pencahayaan masih belum sesuai dengan standar kenyamanan yang berlaku.

Judul: Analisis Tingkat Kenyamanan Termal, Visual dan Audial pada Ruang Kuliah di Gedung Kuliah Baru IPB
Abstrak: PermenPU No. 29/PRT/M/2006 tentang Pedoman Persyaratan Teknis Bangunan Gedung, mensyaratkan beberapa kriteria kenyamanan suatu gedung, diantaranya adalah kenyamanan termal, kenyamanan visual dan kenyamanan audial. Oleh sebab itu, seiring dengan pembangunan Gedung Kuliah Baru IPB diperlukan evaluasi kualitas kenyamanan ruang agar sehingga proses pembelajaran pada ruang kuliah dapat nyaman sesuai dengan standar yang telah ditetapkan. Penelitian dilakukan dengan pengukuran langsung pada ruang kuliah. Data yang diambil adalah hasil pengukuran kelembapan relatif , temperatur, tingkat kebisingan dan intensitas pencahayaan. Penelitian dilakukan pada sebelas ruang dengan rentang waktu bulan April hingga Mei 2021. Penelitian pada ruang kuliah memberikan nilai rata-rata temperatur udara sebesar 24,26 °C, kelembapan relatif udara rata-rata sebesar 71,02 %, tingkat kebisingan rata-rata sebesar 35,19 dB(A) dan intensitas pencahayaan rata-rata sebesar 1214,39 lux. Ruang kuliah sebagian besar sudah sesuai dengan standar yang berlaku untuk parameter temperatur udara, tingkat kebisingan dan intensitas pencahayaan. Namun untuk parameter kelembapan udara dan intensitas pencahayaan pada sore hari masih belum sesuai standar yang berlaku., Minister of Public Works Regulation No. 29/PRT/M/2006 requires several criteria for building comfort, including thermal comfort, visual comfort, and audial comfort. Therefore, along with the construction of the New Lecture Building of IPB, it is necessary to evaluate the quality of the comfort of the room so that the learning process in the lecture hall can run well and comfortably according to the standards that have been set. The research was conducted by direct identification and measurement in the lecture hall. The data were taken to measure the relative humidity of the air, air temperature, noise level and lighting intensity. The study was conducted in eleven rooms with a period from April to May 2021. Research in lecture halls gives an average air temperature of 24.26 °C, average relative humidity of 71.02%, an average noise level of 35.19 dB(A) and average lighting intensity of 1214.39 lux. Most of the lecture rooms follow the applicable standards for parameters of air temperature, noise level and lighting intensity. However, the parameters of air humidity and lighting intensity in the afternoon are still not up to the applicable standards.

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.
