Judul: Perancangan Jaringan Fire Sprinkler pada Gedung Wing V Fakultas Teknologi Pertanian Institut Pertanian Bogor
Abstrak: Menurut Undang-Undang Republik Indonesia Nomor 28 Tahun 2002 tentangbangunan gedung Pasal 17 ayat (1), persyaratan keselamatan gedung mencakupkemampuan bangunan untuk mendukung beban serta kemampuan dalampencegahan dan penanggulangan bahaya kebakaran dan petir. Untuk meningkatkanketahanan gedung terhadap kebakaran, diperlukan sistem proteksi kebakaran yangtepat, seperti instalasi jaringan fire sprinkler sesuai standar BSN dan NFPA.Perancangan fire sprinkler akan diterapkan pada Gedung Wing V pada KampusIPB Dramaga. Metode yang digunakan mengikuti prosedur yang telah ditetapkanoleh BSN dan NFPA. Pada Gedung Wing V Institut Pertanian Bogor dibutuhkan233 kepala sprinkler dengan kebutuhan lantai 1 sebanyak 89 buah, lantai 2sebanyak 82 buah, dan lantai 3 sebanyak 62 buah. Diameter pipa yang digunakanbervariatif dari, According to Undang-Undang Republik Indonesia Number 28 of 2002 onbuilding structures, article 17 paragraph (1), building safety requirements includethe capability to support loads and the ability to prevent and mitigate fire andlightning hazards. An appropriate fire protection system, such as a fire sprinklernetwork compliant with BSN and NFPA standards, is necessary to enhance buildingfire resistance. The fire sprinkler system for the Wing V Building at IPB DramagaCampus will be designed following these procedures. Wing V Building requires233 sprinkler heads, with 89 on the first floor, 82 on the second floor, and 62 onthe third floor, using pipe diameters ranging from

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: Karakteristik Carboxymethyl Chitosan Dengan Variasi Konsentrasi NaOH
Abstrak: Carboxymethyl chitosan is chitosan derivative product obtained from chemical modification. CMCh were made by alkalization process and carboxymethylation process. Factors that affect CMCh characteristics were excess sodium hydroxide in alkalization process, ratio between chitosan and monochloroacetic acid, and carboxymethylation temperature. The objectives of this research were to study the NaOH effect to CMCh characteristics, to learn process of making CMCh, to set the proper concentration of NaOH, and to analyze CMCh characteristics. CMCh yields were 110.72%-114.22%. CMCh pH value were 3.74-4.31. The optimum NaOH concentration to obtain the best CHCh was 10 M. Percentage of CMCh moisture content was 10.70%-11.42%. Ash content and nitrogen content of CMCh were 0.49%-0.50% and 4.52%-4.81%. CMCh viscousity was 8.25 cps. Percentage of CMCh solubility was 61.61%-91.50%. The different functional groups from chitosan which observed in CMCh were C=O group, CH group from alkene functional group, C−O group, and C−O−C group.
