Judul: Analisis Willingness To Accept Terhadap Program Relokasi Masyarakat di Kampung Pulo Kecamatan Jatinegara Jakarta Timur.
Abstrak: The urbanization of people to the city such as Jakarta have increased demands of place to live, which in turn increase price of land. That’s make that people used river side land such as Ciliwung river which is cheaper than another places. That’s impact the river more narrow and flooding when it is raining. The goverment was been relocated the people who was lived at the river side, that can reduce the bad impact of floody, but many people refuse to be relocated. This research took Kampung Pulo which calculated the impact of flooding identifications any factors of the willingness at the people to be relocated, estimations of Willingness To Accept (WTA) Kampung Pulo’s people to be relocated and any factors influence it. The result is most of the people accepted to be relocated with the compensation amount of the Rp 1.174.472.600,-. Society is willing to be relocated with the total compensation amount of the Rp 2.223.899.800,- which the factors that influence it are income and status of home

Judul: Estimasi Kerugian Ekonomi Akibat Banjir Sungai Pesanggrahan di Pemukiman Kedoya Selatan Jakarta Barat
Abstrak: The overflow of Pesanggrahan river is one of the main cause of flood in Kebon Jeruk area, West Jakarta. It causes loss that affects people in the impacted area. There for, the government has conducted river normalization program. This program needs additional land, thus, residents in the area need to be relocated. Most of people are objected to be relocated, and it becomes serious problem for the program. Based on the explanation, the objective of this research are to study residents’ perception towards Pesanggrahan river flood danger risk, to estimate direct and tangible financial loss value in housing sector, and to identify factors that influence residents’willingness to be relocated. Cross section data is obtained through survey that is conducted to 70 respondents in South Kedoya, and multistage random sampling is applied to choose the respondent from all population. Data analytical method consists of Spearman corelation, Stage Damage Function (SDF) application, and logistic regression analysis. The result shows that there is a weak corelation between people’s perception towards the consecuencies happened in the future, with people’s perception in conducting flood mitigations. Beside that, the loss value that have to be bear by each family in the riverside, and in South Kedoya, during January 17th – 19th, 2013 are IDR 3 936 332 and IDR 4 070 167 288 accordingly. If it was assumed that Pesanggrahan river’s normalization program could decrease flood’s depth up to 50%, so total losses value will decrease to 14 %. Aside that, if it was assumed that this normalization program could decrease flood’s duration up to 50%, so total losses value will decrease to 31 %.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
