Judul: Estimasi Kerugian Banjir Sungai Pesanggrahan pada Kawasan Perumahan di Jakarta Selatan.
Abstrak: Ulujami and Kebayoran Lama Utara urban village are the two villages in South Jakarta, that passed by the Pesanggrahan River. The overflowing of the river was a reason of floods in the two areas. The government is running the river normalization program as form of adaptation action of the upcoming flood. Residential areas is one of the areas which was affected by the Pesangggrahan River flood. The general objective of this research was to estimate the number of the loss experienced by the flood in order to make a future scenario with different flood and to measure the benefits of flood protection. The specific objective of this research was to analyze the value of flood losses, reduction of flood losses from the normalization program, risk perception, and community and government adaptation in facing the flood. The method of this research was descriptive analysis, Spearman correlation, and Stage Damage Function (SDF). The result showed that respondents have a low perception of the flood mitigation efforts, although the perception of the consequences of flood was high. Public perception of the expectations of government policy in flood mitigation effort was also high. Flood loss was significantly influenced by the duration of the flood, the frequency of flood occurrence, house size, and household income. Based on estimates, the loss per household was Rp 3 922 300 and the total loss of the two villages was Rp 2 529 883 500. After the normalization program, estimated losses would be reduced by 34.58%. The interview showed that 60% of respondents answered they would do the preparatory adaptation action of flood and 40% answered they would not do the adaptation effort. Adaptation measures against flood by the government, one of which was the Pesanggrahan normalization program.

Judul: Estimasi Kerugian Ekonomi Akibat Banjir Sungai Pesanggrahan Pada Sektor Komersil (Studi Kasus: Kelurahan Ulujami dan Kelurahan Kebayoran Lama Utara, Jakarta Selatan)
Abstrak: Ulujami and Kebayoran Lama Utara urban village are two villages in Southern Jakarta, that passed by the Pesanggrahan River. This urban village is a flood prone area. The objective of this research was to analize the risk perception, value of flood losses, reduction of flood losses from the JEDI program and business people strategy in facing the flood. This research using 40 businessman sample that choosen by purposive sampling method. Flood river that choosen was flood that was happen on 17 january till 19 january 2013. Flood caused by Pesanggrahan River overflow. As one of the flood risk management in order to reduce the impact of the upcoming flood damages, the government now is implementing Jakarta Emergency Dredging Initiave (JEDI) program. Commercial sector in Ulujami and Kebayoran lama Utara urban village is one of the sector of life support which was affected by flood of Pesanggrahan River. The method of this research was spearman correlation, stage damage function (SDF) and descriptive analysis. According to the result, risk perception analysis showed that respondents perception of the flood mitigation effort was lower than respondents perception of expectations of the government flood mitigation policy. According to the loss variables, the loss per business unit was Rp 22 761 173 and the total loss of two villages was Rp 1 229 103 342. Result of the flood estimation losses on commercial sector known that flood loss was affected by the flood depth, duration of the flood, building size and business unit revenue per day. Based on the government JEDI program, estimated losses would be reduced by 38% for the duration of flood reduce, 39% for flood depth reduce and 72% for both of assumption reduce. According to interview result and the observations, that known that business people strategy to facing flood was created table and chair to protect asset, created attic, add of the building floor, raised building floor, created flood dams and incidental strategy.

Judul: Apatite Growth Optimation on Chicken Mucouse by Fourier Transform Infrared (FTIR) Characterization
Abstrak: Some experiment had been conducted to grow apatite from supersaturated solution of calcium phosphate ions on chicken mucouse. The calcium and phosphate ions were originated from Ca(NO3)2 and (NH4)2HPO4. Carbonate ions from (NH4)2CO3 was also used as starting solution. Experiment was carried out within about 5 hours at temperature 370 C and pH 7. Value of Ca+ : PO4 3- was 1.67, while molar ratio of CO3 2- : PO4 3- was 0.5 : 1. Molarity of molar ratio CO3 2- : PO4 3- variated approximately 0.15 : 0.30, 0.51 : 1.02, and 0.90 : 1.80. Mass of mucouse powder was constant 0.75 gram. The analysis result of Fourier Transform Infrared (FTIR) showed that the precipitation was apatite carbonate type A and B. In these experiment it was found out that the mucouse reduce the crystallinity of apatite precipitant, and the growth of apatite crystal was optimum at solution with molar ratio CO3 2- : PO4 3- about 0.15 : 0.30.
