Judul: Strategi dan biaya adaptasi masyarakat teluk Jakarta terhadap dampak banjir rob akibat perubahan iklim
Abstrak: Perubahan iklim berpotensi memberikan dampak pada berbagai aspek kehidupan. Fenomena ini ditunjukkan dengan adanya pencairan es di kutub dan kenaikan permukaan air laut. Salah satu dampak yang ditimbulkan oleh kenaikan permukaan air laut adalah banjir di wilayah pesisir atau yang dikenal dalam istilah Indonesia sebagai rob. Dibutuhkan suatu upaya adaptasi sebagai bentuk tindakan responsif yang dilakukan untuk meminimalisir dan mengantisipasi dampak yang diterima. Oleh sebab itu, penelitian ini dilakukan untuk mengkaji upaya adaptasi masyarakat melalui pendekatan ekonomi sumberdaya dan lingkungan. Tujuan penelitian ini secara khusus yaitu: (1) menginterpretasikan presepsi masyarakat mengenai perubahan iklim dan dampak banjir rob; (2) mengidentifikasi strategi adaptasi yang dilakukan masyarakat dalam mengantisipasi dampak banjir rob; (3) mengestimasi besar biaya adaptasi yang ditanggung masyarakat akibat banjir rob; (4) menganalisis faktor-faktor yang mempengaruhi besar biaya adaptasi masyarakat terhadap dampak banjir rob; dan (5) mengkaji program dan rencana program pemerintah Provinsi DKI Jakarta dan Kotamadya Jakarta Utara untuk mengatasi banjir rob di wilayah Kelurahan Penjaringan dan kesesuaiannya dengan harapan masyarakat.

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.
