Judul: Estimasi Kerugian Usaha Mikro dan Kecil Akibat Banjir Sungai Pesanggrahan (Studi Kasus Kelurahan Kedoya Selatan dan Rawa Buaya Jakarta Barat)
Abstrak: Flood is a routine thing that happens in Jakarta and it is still difficult to overcome by government. Government has conducted various programs to reduce losses due to flooding, such as Pesanggrahan river normalization. Flooding that occured on 17-19 January 2013 caused much damage to the various groups, both of them were micro scale business and small scale business. This research is expected to be useful for policy recomendation basic in flood mitigation program. The specific purpose of this research were to identify businessman’s perceptions about flood risk, to estimate direct damages and losses valueof businesses unit due to flooding, to predicted the lower losses due to flooding after Pesangrahan normalization program, and to analyze the flood vulnerability in businesses unit. Sampling method used is multistage random sampling and analyzes methode used is Spearman correlation, stage damage function and stage damage curve. Results showed the businessmans generally realize that their business location prone to flooding, however not all have the high desire to do something to mitigate flood risk. Respondent tend to expectfrom government program. Estimation results of total structural damages assessment is Rp 258 908 010 and total losses value is Rp 545 848 100. If normalization program goes well and with the assumption can reduce the average height of flood inundation until 72.72% of previous, then total losses value will decrease to 42%. If it can reduce the average flood duration until 96.84% of previous, then total losses value will decrease to 61%. Results of flood vunerability analysis showed that small scale bussiness units are more vulnerable to flooding, and bussines units located in Rawa Buaya are more vulnerable to flooding if related to the flood duration, whereas bussines units located in Kedoya Selatan are more vulnerable to flooding if related to inudation.

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: Electrophoretic Coating of Apatite Compouds on Stainless Steel 316L.
Abstrak: Stainless steel (SS) 316L is a metal which is used to bone plate. However, this metal still has low biocompatibility in a human body. The metal is coated by HAp in order to increase its biocompatibility. HAp on SS 316L is coated by electrophoretic deposition (EPD) method. We used two variables in EPD process, such as voltage and coating time to obtain the best coating. The XRD difractogram showed that SS 316L has been coated by HAp. Physical observation used by microscope optics showed that the best coating is achieved on 120V during 2 minutes.
