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: Analysis of Factors that Influence Community Consumption Patterns on Water Resources in Bogor City (Case Study: PDAM Tirta Pakuan, Bogor City)
Abstrak: Bertambahnya jumlah penduduk dan tingginya aktivitas ekonomi di Kota Bogor menyebabkan pencemaran air serta meningkatnya kebutuhan terhadap air bersih. Hal ini mengakibatkan masyarakat mengonsumsi sumber air utama PDAM untuk memenuhi kebutuhan air sehari-hari, sehingga masyarakat harus menyisihkan sebagian pendapatannya untuk konsumsi air. Penelitian ini bertujuan untuk (1) menganalisis karakteristik dan pola konsumsi masyarakat terhadap air PDAM Tirta Pakuan Kota Bogor, (2) menganalisis pengeluaran rumah tangga dalam konsumsi air PDAM Tirta Pakuan Kota Bogor, dan (3) mengidentifikasi faktor-faktor yang memengaruhi konsumsi air PDAM Tirta Pakuan Kota Bogor. Metode analisis yang digunakan pada penelitian ini yaitu analisis deskriptif, skala likert, analisis pengeluaran, dan analisis regresi linear berganda. Hasil dari penelitian ini menunjukkan bahwa terdapat tiga sumber air yang digunakan dan membentuk empat pola kombinasi air. Sebagian besar pelanggan PDAM mulai dari R1 hingga R8 memberikan penilaian baik terhadap kualitas, tarif, dan kinerja sumber air PDAM. Proporsi pengeluaran air telah memenuhi prinsip keterjangkauan karena tidak melebihi empat persen dari total pendapatan. Faktor yang memengaruhi masyarakat terhadap jumlah pemakaian air PDAM adalah jumlah anggota keluarga, pendapatan, dan sumber air lain yang dimiliki., Population growth and high economic activity in Bogor City cause water pollution and the increasing demand of clean water. This causes the community to consume water supply from PDAM for their daily water needs, so that the community must set aside a portion of their income for water consumption. The purpose of this research are (1) to analyze the characteristics and patterns of public consumption of PDAM Tirta Pakuan water, (2) to analyze household expenditures in water consumption PDAM Tirta Pakuan, and (3) to identify the factors that influence PDAM Tirta Pakuan water consumption. The analysis methods used are descriptive analysis, likert scale, expenditure analysis, and multiple linear regression analysis. The results of this research show that there are three water sources and form four patterns of water use combination. Most PDAM customers from R1 to R8 give a good perception of the quality, tariff, and performance of PDAM water sources. The proportion of water consumption expenditure has met the principle of affordability because it is not more than four percent of the total household income. The factors that influence the community consumption of PDAM water use are number of family members, income, and other water sources they have.

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.
