Judul: Dampak Dinamika Banjir Pasang (Rob) terhadap Sistem Sosial Ekologis Kota Semarang (Studi Kasus di Kelurahan Tanjung Mas)
Abstrak: Region of coastal area of Semarang represents the region with the solid activity complexity. The complexity activities caused the level of pressure at the region. Environmental damage have been seen. Phenomenon that happened until now is tidal floods called rob. If tidal floods handling install is not systematic, estimated Semarang will sink. The aims of this study was to identife social ecological system dynamics, to estimate ecological impact and economic social, to compile indication strategy of management of coastal area base on the adaptation to tidal floods.The result showed that pursuant to historical analysis shows that tidal floods increased in the case of height irrigate and also spread area affected, pond tidal flood resulted the change of structure of social condition and space of area economics affected, analyse the scenario that the development embank the sea (seawall) with the environmental management with of cultivation mangrove alongside embank and drainage basin in physical represent the effective solution in area management. Tidal floods gived magnitude effects not for human and all activities but for the region and ecological system.

Judul: Hubungan kohesi sosial dan resiliensi komunitas terdampak bencana banjir rob.
Abstrak: Bencana merupakan sebuah peristiwa yang berpotensi merugikan kehidupan komunitas. Salah satu bencana yang sering melanda Indonesia adalah bencana banjir. Kota Pekalongan merupakan salah satu daerah yang berisiko tinggi terhadap bencana banjir rob, kehadirannya tidak hanya dipengaruhi oleh kenaikan muka air laut dan hujan, juga dipengaruhi oleh penurunan muka tanah. Bencana dapat melahirkan sebuah kohesi sosial dalam komunitas. Tujuan penelitian ini adalah menganalisis kohesi sosial komunitas, resiliensi komunitas serta hubungan kohesi sosial dan resiliensi komunitas terdampak banjir rob di RW (Rukun Warga) 06 Kelurahan Pasirkratonkramat. Penelitian ini menggunakan pendekatan mix method dengan alat pengumpulan data berupa instrumen kuesioner dan panduan wawancara. Pemilihan responden dilakukan dengan teknik proportional random sampling. Penelitian menghasilkan temuan bahwa tingkat kohesi sosial tinggi, demikian pula dengan tingkat resiliensi yang dimiliki oleh komunitas, namun tidak ditemukan terdapat hubungan antara kohesi sosial dan resiliensi komunitas terdampak banjir rob.

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.
