Judul: Climate Change Risk Assessment in Coastal Area of Jakarta (Study case: North Jakarta City)
Abstrak: Pesisir DKI Jakarta merupakan wilayah yang menjadi prioritas dalam aksi ketahanan iklim karena berpotensi mendapatkan ancaman bahaya dari laut dan daratan. Penilaian risiko perubahan iklim bertujuan memetakan wilayah berdasarkan tingkat risikonya terhadap ancaman bahaya iklim di masa depan yaitu, cekaman panas, hujan ekstrem, cekaman kekeringan dan banjir rob sekaligus memberikan rekomendasi aksi pada wilayah prioritas. Wilayah dengan kategori risiko sangat tinggi dipengaruhi oleh tingkat ancaman bahaya yang tinggi, profil wilayah yang mudah terpengaruhi oleh dampak buruk, kepadatan penduduk yang tinggi namun rendah pada kapasitas untuk merespon bahaya. Wilayah dengan tingkat risiko rendah memiliki ancaman bahaya rendah dan rendahnya potensi dampak buruk yang dapat dirasakan masyarakat, atau tingginya kapasitas kewilayahan dalam merespon dampak bahaya yang dapat meredam tingkat risiko pada ancaman bahaya tinggi. Lokasi berisiko tinggi paling banyak berada di Kecamatan Cilincing, Tanjung Priok, dan Koja sedangkan wilayah yang tidak terdapat risiko tinggi yaitu Kecamatan Kelapa Gading. Kecamatan dengan wilayah prioritas terbanyak berada di Kecamatan Cilincing, Penjaringan, dan Koja. Berdasarkan identifikasi terhadap indikator aksi yang perlu diintervensi dapat difokuskan pada sektor kesehatan, ekonomi, lingkungan dan infrastruktur, karena sebagian besar wilayah prioritas memiliki kekurangan pada sektor tersebut yang perlu diintervensi untuk menurunkan tingkat risiko., Coastal area of DKI Jakarta is a priority area in climate resilience action because it has the potential to experience hazard from the sea and land. Climate change risk assessment aims to map areas based on their risk level for future climate hazards, such as heat stress, extreme rainfall, drought and tidal floods, as well as providing recommendations for action in priority areas. Locations with a very high risk category are influenced by a high level of hazard, easily affected by adverse impacts, high population density but low capacity to respond to hazards. Locations with a low risk level have a low level of hazard and a low potential for adverse impacts that can be felt by the community, or a high regional capacity to respond the impact of hazard which can reduce the level of risk. The most high-risk locations are in Cilincing, Tanjung Priok and Koja Districts, while the areas where there is no high risk are Kelapa Gading District. The locations with the most priority areas are Cilincing, Penjaringan and Koja Districts. Based on the identification of indicators that need intervention on action, it can be focused on the health, economic, environmental and infrastructure sectors, because most priority areas have deficiencies in these sectors that need intervention to reduce the level of risk.

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: 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.
