Judul: Aktivitas Pendaratan dan Pemasaran Hasil Tangkapan di Pangkalan-Pangkalan Pendaratan Ikan Kabupaten Ciamis
Abstrak: Marine fisheries activities at Ciamis Regency is supported by the fishing landing bases (PPI) spread out over 5 sub-district. Some of the activities in these PPI are landing and marketing of fish catches. Both of these activities require adequate facilities and careful handling because fish is a perishable commodity. The purpose of this research are to know the actual condition of the fishing ports, the activity of landing and marketing of fish catches in 5 locations of PPI at Ciamis Regency. This research used the survey method and descriptive data analysis. The results showed that fishing port facilities in 5 locations of PPI at Ciamis Regency is still very lacking. All of PPI at Ciamis Regency uses beach and estuary of the river as a place for landing of the fish catches. PPI Batu Karas has the most of number and volume of landing fish catches than the others. The fishes landed on all of PPI at Ciamis Regency are marketed through the fish-trading activity, except at PPI Pangandaran. The fishes are marketed for consumption of local communities around the PPI, inside and outside of the Ciamis Regency. Some types of fish that has high economic value such as shrimp, lobster and hairtails are exported to Japan, China and South Korea. NP/P ratio and relative value of production index gained PPI Kalipucang in 2010 is bigger than the others. This is because the fish were landed at this PPI are homogeneous, consisting only of lobster that has high economic value.

Judul: Prakiraan Dampak Pemindahan Lokasi Pelabuhan Perikanan terhadap Aktivitas Nelayan dan Pedagang Ikan (Studi Kasus: PPI Pangandaran Kabupaten Ciamis)
Abstrak: Fish landing base (PPI) Pangandaran is one of productive PPI in Ciamis Region. Fish landing base was originally located on the eastern shore of Pangandaran, but subsequently moved to Village Babakan Pangandaran. The transference of the PPI Pangandaran to the village of signing intended to reorganize Pangandaran of tourism in the region. According to the local government, the act of fisherman who tether the boat on the west coast, the east coast pangandaran and preserve nature pananjung can disrupt the activities of tourism and conservation in the area. Fishermen and fish traders alleged to constitute the most widely accepted impact of removal of PPI. This research was conducted to find out the actual conditions, the impact of the transfer of the PPI Pangandaran to the fishermen and fish traders activity and know the strategy of developing PPI Pangandaran. Research methods used are case studies with descriptive data and SWOT analysis. A descriptive analysis of the results shows that the forecast impact of removal of PPI Pangandaran fishermen and merchants against fish is an increase in costs that must be incurred by fishermen and fish merchants as a result away a new location, it is next to the impact reduced income. The new location of PPI away cause PPI and a long time to return home to be incremented. The SWOT analysis results showed that development of the PPI should do in Pangandaran, West Java's old location.

Judul: Solusi Geometri Schwarzschild untuk Dimensi 4+1 dengan Invarian Rotasi Isotropik.
Abstrak: Metrik Schwarzschild merupakan solusi eksak pertama dari persamaan medan Einstein dengan mangasumsikan metrik statik dan simetris. Metrik Schwarzschild yang ditemukan oleh Karl Schwarzschild masih dalam dimensi 3+1, namun seiring dengan teori-teori terbaru yang menunjukkan bahwa alam semesta tidak hanya di dimensi 3+1. Maka melalui penambahan dimensi, tujuan penelitian ini memperoleh solusi pada geometri Schwarzschild untuk dimensi 4+1 dengan memodifikasi koordinat bola yang invarian rotasi isotropik dan melalui penurunan rumus seperti koordinat bola, simbol Christoffel, dan tensor Ricci. Selain mendapatkan solusi ini, metrik Schwarzschild dimensi 4+1 dapat digunakan sebagai metrik dasar untuk memperoleh solusi blackhole dan wormhole pada dimensi 4+1. Hasil akhirnya, dengan memanfaatkan modifikasi koordinat bola, metrik Schwarzschild dapat dibentuk sehingga diperoleh solusi geometri Schwarzschild untuk dimensi 4+1.
