Judul: Arahan Pengembangan Sistem Penyediaan Air Minum Kota Bogor
Abstrak: Population growth and socioeconomic development are currently driving a rapid increase in water demand, especially from household sectors at Bogor City. Meanwhile availability of fresh water is likely to decrease since lack of water resources, climate change, water pollution, over-exploitation of ground water and low efficiency of water usage. Therefore, municipal water management is an important factor and water supply system becomes most essential duties of the government. The objectives of this research are: (1) to analyze the balance of water supply and water demand at Bogor’s water supply system , (2) to perform spatial analysis on regions where the populations have (and not) been served by PDAM water distribution system, (3) to formulate the direction for development of water supply system at the study sites. The results show that water demand in 2031 can not be satisfied, where water supply would have a lack around 1 252 liters per second. EPANET 2.0 simulation show 7 kelurahan potentially underserved by PDAM pipe-based water distribution system, due to its high elevation and low water pressure on pipe. The primary strategy for development of water supply system at Bogor is to push the development of water supply system by PDAM - as the first priority and promote the use of communal-based wells water supply for the areas that are technically (and or economically) difficult to be served by PDAM water distribution system.

Judul: Analisis kebutuhan dan ketersediaan air bersih di daerah pelayanan zona 1 PDAM Tirta Pakuan Bogor, Jawa Barat
Abstrak: Bogor merupakan kota dengan kepadatan penduduk cukup tinggi. Pada tahun 2014 pertumbuhan penduduk kota Bogor mencapai 1.89% per tahun. Perubahan peningkatan jumlah penduduk akan mengakibatkan kebutuhan air bersih juga meningkat, sehingga diperlukan adanya perencanaan kebutuhan dan ketersediaan air bersih. Penelitian ini bertujuan untuk, menghitung jumlah kebutuhan air bersih, menghitung debit ketersediaan air bersih, dan menentukan alternatif untuk penambahan sumber air dalam pemenuhan kebutuhan air bersih sampai tahun 2035. Penelitian dilaksanakan di daerah pelayanan zona 1 Perusahaan Daerah Air Minum Tirta Pakuan kota Bogor. Pengambilan data dilaksanakan pada bulan April – Mei 2016. Dari hasil penelitian didapatkan bahwa kebutuhan air domestik di daerah pelayanan zona 1 sebesar 231.55 liter/detik dan kebutuhan air non domestik sebesar 18.58 liter/detik, sehingga total kebutuhan air bersih di daerah pelayanan zona 1 sebesar 300.16 liter/detik. Debit ketersediaan air bersih daerah pelayanan zona 1 diprediksi mengalami penurunan menjadi 173.332 liter/detik pada tahun 2035. Dengan demikian, terjadi defisit air sebesar 124.82 liter/detik, dan diperlukan penambahan air baku yang bersumber dari air permukaan yaitu dari Sungai Cikreteg sebesar 200 liter/detik.

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.
