Judul: Analisis Kerusakan dan Strategi Pencegahan Banjir Rob Akibat Perubahan Iklim di Jakarta Utara
Abstrak: North Jakarta is an area that is vulnerable to climate change. One of the impacts of climate change that occurred in North Jakarta is a tidal flood caused by rising sea levels. North Jakarta is Jakarta area directly adjacent to the Java Sea. Location of North Jakarta that led to this area is very vulnerable to flooding due to sea level rise. Besides flooding that occurred rob exacerbated by conditions in North Jakarta which is under sea level and land subsidence. This research was conducted in three urban village prone to tidal flooding Penjaringan, Kamal Muara and Marunda. The purpose of this study are to estimate the index of vulnerability to climate change in North Jakarta, estimate the value of losses due to tidal flooding in North Jakarta, to analyze strategy and preventive cost caused by tidal flood, Analyze the factors that affect the preventive costs to protect against the tidal flood and to identify local goverment strategy. This study use five methods of analysis: (1) Livelihood Vulnerability Index (LVI), (2) environment damage assessment, (3) Averting Behaviour Method (ABM), (4) and multiple linear regression (5) AWOT. The result shows that the LVI of Penjaringan is 0,455, and this index is the highest LVI compared to another village. Total losses due to tidal flood that occurred in January 2014 was IDR. 137.026.419.716. The household do preventive measures against tidal flood with a variety of ways including moving goods, make levees, elevate the floor and add to the floor of the House. While the majority of the business unit performing preventative measures by way of making the levee and elevating the floor business units and public facilities the majority do precautions with elevated ground floor and move the stuff. The total cost of prevention at this research is IDR. 440.104.897.882. Factors affecting the magnitude of the costs of prevention for households affected by the inundation, high income, duration of the flood, and the level of education. The magnitude of the costs of the prevention business units affected business units of building area, height, distance to the sea, long effort and duration of inundation. As for the public facilities affected by the distance to the high seas, the water level, inundation duration, and frequency of floods. The strategy that became a top priority for tackling tidal flood in North Jakarta on this research is running a North Jakarta RTRW already listed on RTRW province of Jakarta.

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: Sintesis dan Pencirian Kompleks Fe(III)-Kuersetin
Abstrak: Quercetin belongs to flavonols which is able to chelate metal ions. Quercetin may chelate metal ions at 3’,4’-catechol, 3- or 5-hydroxycromone sites. In this study, quercetin was complexed with Fe(III). The complex with Fe(III) ions from FeCl3·6H2O was more stable than the complex derived from Fe(NO3)3·9H2O. The quercetin was yellow in color and showed maximum wavelengths (λ􀭫􀭟􀭶) at 250 and 370 nm. The Fe(III)-quercetin complex from Fe(NO3)3·9H2O was yellowish green with 􀟣􀭫􀭟􀭶 at 280 and 420 nm, whereas that from FeCl3·6H2O was dark green with 􀟣􀭫􀭟􀭶 at 280 and 430 nm. The 􀟣􀭫􀭟􀭶 shift indicated that the complex was formed at 3-hydroxychromone site. The Fe(III)- quercetin complex was formed with 1:1 metal-ligand mole ratio based on atomic absorption spectrophotometry analysis and the X-ray diffractogram showed that the crystallinity of the complex was 37%.
