Judul: Peran Kelompok Nelayan dalam Kegiatan Pariwisata terhadap Peluang Usaha dan Kerja
Abstrak: The purpose of this study was to analyze the role of fishermen in the tourism activities of the business and employment opportunities. This study also examines the relationship between the characteristics of the group members and group elements with the role of fishermen, where the research was conducted on a group cruise boat belonging to the Organization of Boat Cruise Pangandaran (OBCP) Pangandaran Village. On testing the characteristics of group members to the role of fishermen, there was a real relationship. In the test group elements with the role of fishermen, there was a real relationship unless the relationship norms/rules of the group with the group supporting service units were not real relationships. Finally, in testing the role of fishermen and businesses and employment opportunities, there was a real relationship, this was evidenced by the presence of several members of the group who has other business other than as a fisherman or a boat cruise as homestays, restaurants and stalls.

Judul: Dampak Pengembangan Pariwisata dan Sikap Nelayan di Desa Pangandaran
Abstrak: Development of coastal tourism can give directly impact on the social and cultural life of fisherman communities and influence the attitudes of fishermen. This study intend to analyze the impact of tourism development on the social structure and cultural values as well as analyzing the attitudes of fishermen towards the tourism development. The research was conducted in Pangandaran village using survey methods. The results showed that the development of tourism impact on the social structure of fishermen namely the growth of social organization, social stratification, migration and composition of the population, as well as the livelihoods and incomes. Whereas the impact on the cultural value of fishermen include namely the waning tradition of local fishermen, fishermen lifestyle changes, and increased knowledge of fishermen. Fishermen status and income level have a real relationship with the attitude of fishermen, whereas age and education level did not have a real relationship with the attitude of fishermen

Judul: Transisi Fasa Materi Hadronik ke Materi Kuark pada Inti Bintang Neutron.
Abstrak: Bintang neutron terdiri dari beberapa lapisan yang disusun oleh materi nuklir yang berbeda dengan kerapatan yang semakin tinggi ketika mendekati pusat bintang. Inti luar bintang neutron disusun oleh materi hadronik (nukleon, lepton, dan hyperon), sedangkan inti dalam bintang neutron disusun oleh kuark-kuark bebas (up, down, strange) yang saling berinteraksi. Tujuan penelitian ini adalah mempelajari bagaimana transisi dari inti luar ke inti dalam bintang neutron dengan menggunakan pendekatan RMF (Relativistic Mean Field) untuk materi hadronik dan CIDDM (Confined Isospin Density Dependent Mass) untuk materi kuark. Tekanan transisi diperoleh ketika potensial kimia barion materi hadronik dan materi kuark bernilai sama. Nilai tekanan transisi dengan parameter SU6-TM1 sekitar 87 MeV/fm3 dan diperoleh massa maksimum bintang neutron yaitu 1.92M dengan jari-jari sekitar 8.62 km. Nilai tekanan transisi dengan parameter SU6-G2 sekitar 53 MeV/fm3 dan massa maksimum bintang neutron yaitu 1.88M dengan jari-jari sekitar 8.16 km. Jenis transisi fasa adalah orde satu ditandai dengan diskontinuitas dalam kerapatan energi (adanya mixed phase). Parameter-parameter pada model nuklir yang digunakan menyebabkan perbedaan kekakuan persamaan keadaan (EOS) dari materi hadronik dan materi kuark sehingga nilai tekanan transisi dari fasa hadronik ke fasa kuark juga berbeda.
