Abstrak: The Information technology becomes one of the best options for companies which addresses the power of information as a competitive advantage in globalization era.The Directorate General for Monitoring and Controlling Marine and Fisheries Resources especially the Directorate of Monitoring Fishery Resources of Ministry for Marine and Fisheries has a role to manage marine and fisheries resources and to utilizehems as well as to maintain the potential of fisheries resources in Indonesia. The Directorate of Monitoring Fisheries Resources in carrying out its tasks and functions has not been supported yet by a sophisticated information system. To create that kind of system information, need to do well plan, to carry out a research, then to develop software and finally to implement the system information for fisheries monitoring. This system information will hopefully support the accomplishment of an effective fishery monitoring activities. The development of system information management for fisheries monitoring follows the system development life cycle method. Start from identifying and formulating the current problems, and then designing the conceptual system consists of database structure and flow of processes, develop a software engineering using Microsoft Access and Visual Basic software in order to produce, user friendly menu or windows which are easily accessed by users.

Abstrak: Good data collection system is important factor in gaining an efficiency that will create an advantage, especially on fisheries data collection. However, fisheries data collection system in Sukabumi is still very simple and done with the manual system. Seeing the potential of Sukabumi fisheries, we need a system design of effective and efficient data collection in order to improve the performance of any part of the ports in Sukabumi. This study aimed to design a system of web-based fisheries database that can be accessed by any institution in Sukabumi and can be used as consideration in decision-making on fishery policy in Sukabumi. The analysis used is the development of a system that aims to produce an effective operating system based on the information needs of the user by using My SQL (Structure Query Language) and PHP (Hypertext Processor). The results of the analysis have shown that the fisheries data collection system can be identified on data of Sukabumi into 10 parts, production, ports, fishing, boats, type of boats, fishing gear, kind of catch, KUB (Joint Business Group), fisheries enterprise and managing user menu. The web-based application data management process is expected to be more structured and more efficient so as to support the fishing activities in Sukabumi.

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.
