Judul: Sistem Pakar Identifikasi Hama pada Tanaman Kelapa dan Kelapa Sawit.
Abstrak: The decreasing of coconut palm and oil palm productivity, as export commodities, was caused by continuously plant pest. This expert system can be used as a tool to identify the kinds of infections on the coconut palm and oil palm, and how to treat the pest according to the damage indications which can be seen on the outside of the plants, such as leaves, blossoms, and fruits. This expert system was developed using software lifecycle method in its design and development. This system was made using web programming language PHP and MySQL in its database organization. The kind of representation used is rules with forward chaining. With this system, user can identify the kind of infections on the coconut palm and oil palm according to the indications submitted by user. This system is also able to add, change, and delete the indications and the result of consultation which done by admin.

Abstrak: Soybean is one of the commodities that is instrumental in food needs. However, Indonesia has not been able to fulfill its own need of soybean. Some problems faced by soybean farmers include the selection of good varieties, disruption of pest and diseases. Because of the limitations of experts to disseminate information about soybeans, it is necessary to build a system that can manage and store information so that the information can be easily accessed. To this end, we utilize the system development life cycle to develop information of soybean pests and diseases into an information system kedelai.ipb.ac.id. This method consists of five stages, namely: planning, analysis, design, implementation, and support. A Drupal core is used in the implementation of the information system in this research. The research result consists of two parts namely the information of pest and disease. The information of pest consists of the pest characteristics, indications, and controls. The disease information consists of disease characteristics, indications, and controls.

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.
