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: Perancangan Pemanenan Air Hujan Dengan Konsep Roof Catchment di Gedung Mandiri Innopreneurship Center IPB University
Abstrak: Bogor merupakan salah satu kota di Indonesia yang terkenal dengan curah hujan yang sangat tinggi sepanjang tahunnya. Penelitian ini bertujuan mengetahui volume air hujan yang dapat dipanen, menghasilkan rancangan sistem pemanenan air hujan, menghasilkan rancangan anggaran biaya konstruksi dan menganalisis nilai efektivitas dan efisiensi penghematan sistem PAH. Penelitian dilakukan pada bulan Maret-Mei 2024 yang berlokasi di Gedung Mandiri Innopreneurship Center IPB University. Data curah hujan menggunakan data curah hujan 24 tahun terakhir (tahun 2000-2023) yang diperoleh dari stasiun BMKG Jawa Barat. Potensi volume air hujan yang dapat di panen dengan konsep roof catchment sebesar 892,4 m3/tahun. Hasil perancangan sistem pemanenan air hujan terdiri dari saringan, first flush diverter, tangki FRP, talang air dan perpipaan. Dimensi talang yang digunakan berukuran 200 mm dengan kemiringan 2%. sedangkan, dimensi pipa tegak dan pipa datar menggunakan ukuran 100 mm dengan kemiringan pipa datar sebesar 4%. Kapasitas tangki FRP yang digunakan sebesar 28.000 liter. Rancangan Anggaran Biaya (RAB) konstruksi yang diperlukan untuk perancangan sistem pemanenan air hujan sebesar Rp 105.374.000,00. Efektivitas sistem PAH mencapai 80%. Sistem pemanenan air hujan yang direncanakan dapat mereduksi biaya sebesar 21% atau Rp 1.704.169,00 per tahun Kata Kunci: curah hujan, pemanenan air hujan, tangki frp, Bogor is a city in Indonesia which is famous for its very high rainfall throughout the year. This research aims to determine the volume of rainwater that can be harvested, produce a rainwater harvesting system design, produce a construction cost budget and analyze the effectiveness and efficiency of PAH system savings. The research was in March-May 2024 at the Mandiri Innopreneurship Center IPB University Building. Rainfall data uses rainfall data for the last 24 years (2000-2023) obtained from the West Java BMKG station. Potential volume of rainwater is 892,4 m3/year. The results of the design of the rainwater harvesting system consist of a filter, first flush diverter, FRP tank, gutters and piping. Dimensions of the gutter used are 200 mm with a slope of 2%. Dimensions of the standpipe and flat pipe are 100 mm with a flat pipe slope of 4%. The capacity of the FRP tank used is 28.000 liters. The draft construction (RAB) required for designing a rainwater harvesting system is IDR 105.374.000,00. The effectiveness of the PAH system reaches 80%. The planned rainwater harvesting system can reduce costs by 21% or IDR 1.704.169,00 per year. Keywords: rainfall, rainwater harvesting, FRP tank

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.
