Judul: Rancangan Sistem Penampungan Air Hujan Pada Bangunan Hijau Di Kampus IPB Dramaga Bogor
Abstrak: Indonesia merupakan negara beriklim tropis dengan curah hujan rata-rata yaitu antara 2.000-4.000 mm/tahun (KLH 2009). Potensi air hujan yang tinggi belum termanfaatkan secara optimal. Siklus hidrologi memegang peranan penting dalam menjaga ketersediaan air di permukaan bumi. Penelitian ini bertujuan menyusun desain penampungan air hujan, menghitung kebutuhan air domestik, dan menghitung persentase kebutuhan air domestik yang disuplai dari air hujan pada gedung kuliah baru IPB. Penelitian ini menggunakan data curah hujan harian 10 tahun terakhir, yaitu dari tahun 2010-2019 dengan acuan SNI 03-7065-2005 dan SNI 8153:2015. Hasil penelitian ini berupa Ground Water Tank (GWT) berukuran 6 x 4,5 x 4,5 x 0,3 m dengan kapasitas 121,92 m3 yang dapat memenuhi kebutuhan air gedung sebesar 78,90 %. Penelitian ini menggunakan sistem atap sebagai catchment area dari ground water tank. Debit andalan yang didapat berdasarkan luas area atap sebesar 53,65 m3. Penilaian Greenship kategori aspek konservasi air memperoleh poin sebesar 17 poin dari total 21 poin yang tersedia dengan dua tolak ukur prasyarat. Rancangan Anggaran Biaya (RAB) pembuatan ground water tank di gedung kuliah baru IPB sebesar Rp 347.905.662., Indonesia is a tropical country with an average rainfall of 2,000-4,000 mm/year (KLH 2009). The high potential of rainwater has not been utilized optimally. The hydrological cycle plays an important role in maintaining the availability of water on the earth's surface. This study aims to develop a rainwater storage design, calculate domestic water needs, and calculate the percentage of domestic water needs supplied from rainwater in the new IPB lecture building. This study uses daily rainfall data for the last 10 years, namely from 2010-2019 with reference to SNI 03-7065-2005 and SNI 8153:2015. The results of this study are Ground Water Tank (GWT) measuring 6 x 4,5 x 4,5 x 0.3 m with a capacity of 121,92 m3 which can meet the building's water needs of 82,90%. This study uses a roof system as a catchment area of the ground water tank. The mainstay discharge obtained based on the roof area is 53,65 m3. The Greenship assessment in the water conservation aspect category received 17 points out of a total of 21 points available with two prerequisite benchmarks. The Draft Budget (RAB) for the construction of a ground water tank in the new lecture building of IPB amounted to Rp 347.905.662.

Judul: Rainwater Harvesting System Design in International  Dormitory of IPB Dramaga Campus
Abstrak: Curah hujan yang tinggi di Bogor mencapai 3500 mm melebihi rata-rata curah hujan nasional antara 2000 – 3000 mm. Pemanenan air hujan cocok untuk dilakukan sebagai langkah konservatif yang dapat dilakukan IPB University dalam upaya pemeliharaan sumber daya air yang berkelanjutan. Penelitian ini bertujuan mengetahui banyaknya suplai air hujan yang dapat dipanen, menghasilkan desain sistem PAH serta RAB instalasinya, dan mengetahui penghematan air serta biaya yang dapat dicapai melalui sistem PAH. Penelitian dilakukan dari Februari – Mei 2024 dengan pengambilan data primer berupa luas atap bangunan dan informasi kebutuhan air bersih, serta data sekunder berupa curah hujan tahun 2000 – 2023 Stasiun BMKG Jawa Barat. Potensi volume air hujan yang dapat dipanen 1230 – 2134 m3 dengan rata-rata suplai 1603 m3 per tahun. Desain sistem pemanenan PAH yang dirancang menggunakan tangki FRP berkapasitas 28 m3 dengan dimensi 7 m x 2 m x 2 m. Talang dipasang dengan kemiringan seragam ½% dan pipa datar dengan kemiringan seragam 1%. Variasi ukuran pipa dan talang yang digunakan antara 1 – 10 inch. Besarnya biaya yang dibutuhkan untuk instalasi PAH sebesar Rp143.000.000,00. Penghematan air aktual yang dapat tercapai melalui sistem PAH sebanyak 44% – 75% dari kebutuhan air tahunan dan menghemat biaya lebih dari 120% dari investasi awal., High rainfall in Bogor reached 3500 mm, exceeding the national average rainfall between 2000 – 3000 mm. Rainwater harvesting is conservative step that IPB University can take to maintain sustainable water resources. This research aims to determine amount of rainwater supply that can be harvested, created PAH system design and installation RAB, and determine water and cost savings that can be achieved through PAH system. The research was conducted from February – May 2024 by collecting primary data of building roof area and information of clean water needs, and secondary data of rainfall from 2000 – 2023 from West Java BMKG Station. Potential harvested volume of rainwater is 1230 – 2134 m3 with average supply 1603 m3 a year. The harvesting system design uses a 28 m3 FRP tank with dimensions 7 m x 2 m x 2 m. The gutter is installed with slope of ½% and the flat pipe with slope of 1%. Variations in pipe and gutter sizes used are between 1 – 10 inches. The cost required for PAH installation is IDR143,000,000.00. Actual water savings that can be achieved through PAH system are 44% – 75% of annual water needs and cost savings of more than 120% of the initial investment.

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.
