Judul: Analisis Perhitungan Sumur Resapan dan Kebutuhan Air di Persemaian Permanen Kampus IPB Dramaga
Abstrak: Program green campus 2020 Institut Pertanian Bogor perlu mempertimbangkan pengelolaan air permukaan salah satunya dengan pembangunan sumur resapan. Penelitian ini bertujuan untuk menghitung jumlah sumur resapan pada lokasi penelitian dan jumlah kebutuhan air di persemaian permanen IPB. Pendugaan limpasan menggunakan metode SCS-CN didapatkan nilai sebesar 46 496 m³ dengan luas lahan terbangun 19 400 m². Koefisien permeabilitas tanah diperoleh 0.508 m/jam di Asrama PPKU, 0.234 m/jam di persemaian permanen, 0.198 m/jam di Mesjid Al Hurriyah dan 0.378 di Wisma Landhuis. Jumlah sumur yang harus dibangun pada lokasi penelitian adalah 36 unit di asrama PPKU, 2 unit di persemaian, 19 unit di Al Hurriyyah, 14 unit Wisma Landhuis, 2 unit di kantin RC dan 8 unit di SMA Kornita. Jumlah air yang diresapkan pada lokasi penelitian adalah 10 m³ di asrama PPKU, 18 m³ di persemaian, 21 m³ di Al Hurriyyah dan 14 m³ di Wisma Landhuis. Kebutuhan air persemaian permanen Dramaga Bogor didapatkan sebesar 95.58 m³/hari atau 21 413.46 m³ selama 260 hari tidak terjadi hujan. Jumlah tersebut setara dengan 6 buah sumur resapan yang harus dibangun untuk memenuhi kebutuhan air di persemaian supaya sumur di persemaian permanen tidak kering.

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: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
