Judul: The Development of Spatial Decision Support System for Industrial Wastewater Monitoring (A Case Study: Upper Citarum River Basin, West Java)
Abstrak: The study aims to make an industrial pollution monitoring application system as a prototype system, called IWMS System (Industrial Waste Water Monitoring Support System). IWMS System should give some spatial information to support the government decision for the industry monitoring. It is designed in accordance with industrial profile, pollution monitoring reports and the Government Regulation in the format of Water Quality Standard. Upper Citarum River Basin is selected as the study area due to: (1) The river is one of the high priorities river basin in Indonesia, (2) The region covers the Capital City of West Java, which has a lot of important activities, (3) Many industries are located in this river basin with negative impacts that should be managed, (4) The subject of study should not be too wide, and can be implemented to the other river basins especially in Indonesia; and (5) There is a specific management to achieve the sustainable development, without disruption to the economic growth in this area. The objectives of this study are: (1) To develop the DSS of industrial wastewater monitoring system as an application system to support the Government Decision, and (2) To implement the IWMS as a prototype of the system. IWMS has capability to support the decision in environmental management. At least 13 decisions support can be resulted in this system, e.g.: Visualization of Industry, vi Visualization of Monitoring Site, Comparing the Chart Pattern, Identifying Polluted Industry, Identifying Polluted River, Findings of Industrial Compliance Level, Findings of the Priority Scale of River, Quick Response of Environmental Cases, Findings of the Potential of Polluted Industry, Water Intake and Exploration Control, Reward & Punishment based on Possessing of License, Reward & Punishment based on Possessing of Environmental Document, and Estimation of BOD Potential (sources).

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.
