Abstrak: Milk is a strategic commodity consumed by Indonesian citizens from toddlers until old one. However, in reality milk production in Indonesia is very low and could not fulfill existing demand. Governments have imported this commodity in a huge amount, of about 70% of milk required in Indonesia. An integrated system is required to help users, particularly business executives in the field of agroindustry milk. The purpose is to provide useful information as consideration source and reference for them to study or investigate the planning and decision for development, executives will be able to make decision quickly, precisely, and accurately. The scope of this research is in West Java and its districts, as the center of the milk business. In addition, the scope for commodities discusses including cheese, butter, yoghurt, fresh milk, and powder milk. This research methodology consisted of three steps, were analyzing, designing/prototyping used a function directional decomposition (DFD/Data Flow Diagram), and prototyping system consisting of design, implementation, and verification system. Executive information system (EIS) contains are critical success factor needed to identify the needs of executive, drill down capability that can provide detailed information of the displayed summary, and graphical user interface that displays the interface in the form of graphs. This work was called as Exemil 1.0 which had six informations reviewed, consisted of farming/livestock, marketing, production-consumption, production planning, location development, and financial feasibility information. The development of GUI consisted of two types of graph that appeared in the monitoring report Exemil 1.0, were the shape of a bar graph that displayed threedimensional development of agroindustry and speedometer which showed the percentage growth rate agroindustry milk. The result is conducted to see an appropriate output with a comparison tool. One of verification is carried out on PPIC subsystem. From these data, obtained output forecast demand. Output generated by Microsoft Excel 2007 by using the five methods of time series are single moving average: 610750 kg, double moving average: 621687 kg, single exponential smoothing: 612281 kg, Brown’s method: 613651 kg, and Holt’s method: 588708 kg. While the output generated by Exemil 1.0 was 610750 kg. The result was the same with one of the techniques using Excel 2007. For implementation purposes, Exemil 1.0 is an integrated system of milkbased agroindustry in West Java that allows executives to make decision easier, but still needed

Abstrak: The government campaigned “Milk Drink Campaign”, so as to make it succesful, the milk industry must increase their production. But the national milk production fulfiled 25% from the national milk needed so the other 75% is by import. It can happen by inefficiency to use resources that can make minimum production and this reason are decreases productivity. Because of that, the milk industry needs a tool to facilitate to count and control productivity. The objective of this research is to design, expand, and apply intelligent decission support system for controlling the productivity in the milk industry, to integrate genetic algoritms and expert system in this Intelligent Decission Support System for solve the productivity problem, and to the integration approach productivity that are labor, material, energy, machine and other expense productivity in the intelligent decision support system. The name of the intelligent decision support system of controlling productivity in milk industry is IDSS_MP. This model consists of 9 models that are base model of total output, labor productivity, material productivity, energy productivity, machine productivity, of other expense productivity, total productivity, decision quantity from packaging labor, and model of consultation from expert. The verification of this base model used data from January until June 2008. The quantity selling in June 2008 was chilled milk 3.488.669 kg, prepack milk 188.739 pack and cup milk 387.662 cup. The objective from the base model of total output was to know the total income in one month. The result in June 2008 is Rp 12.096.903.190. The objective from the base model of labor productivity was to know the value of labor productivity and this index. The labor in MT KPBS consists of 12 levels and 8 head levels that consist of 3 parts those are candidate labor, contract labor and permanent labor with a different salary. The result of that the value of labor productivity in June 2008 was 175,175 with index 1,062. The objective from the base model of material productivity was to know the value of material productivity and this index. This material used 3 products. In the end of Mei 2008, the price of fuel had been increased so that it could influence the price of material that increased 20%. The result of that the value of material productivity in June 2008 was 1,191 with index 1,077. The objective from the base model of energy productivity was to know the value of energy productivity and this index. This energy was fuel (diesel fuel and diesel industry), electricity and water. In the end of Mei 2008, the price of fuel was increased so that it influenced the price and quantity in use. The result of that the value of energy productivity in June 2008 was 37,052 with index 0,965. The objective from the base model of machine productivity was to know the value of productivity and index productivity of prepack machine and cup machine whether operation machine was good or not. The result of that the value of prepack machine productivity was 0,970 with index 0,997 and the value of cup machine productivity was 0,982 with

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.
