Judul: Pengembangan Program Komputer untuk Pemilihan Kincir Angin Pembangkit Tenaga Listrik di Pedesaan
Abstrak: Rural areas which have not getting electricity networks provided by Perusahaan Listrik Negara or PLN can consider constructing windmills to generate electricity. In the construction of these windmills, a special attention should be paid to such factors as topography of the location and wind speed in the site of windmills so that a proper type of windmills that will be used in the area can be decided. Therefore, developing a computer program for selecting the type of windmills used is expected to serve as an input for the development of agricultural technologies that utilize renewable energy. Making the computer program consists of the following steps: making the initial view layout of the program, program scripts, animation, and program evaluation. Making a program design is started by determining the input and output components of the program so as to set the initial view of the program. Based on the formulas used for windmills generating electricity, a computer program to determine the type of windmills was developed by using Visual Basic 6.0. Meanwhile, Adobe Flash CS3 Professional software was used to construct animated windmills, which can also be run under Visual Basic 6.0 program.

Judul: Rancang Bangun Kincir Angin sebagai Pembangkit Listrik Pulau – Pulau Kecil (Tipe Savonius)
Abstrak: Electrification ratioin Indonesia until 2009 reportedly reached an average of 66%, but ine astern Indonesia has not reached 45% include small islands. The condition is still felt not to find the principles of justice and equity. This study aims to desain, construct, and testing a savonius windmill type as power plants, that has a good performance in generating electricity. Constructing the windmill was through three stages, that is design, manufacture, and testing. The results showed that the prototype windmill has made a good performance. There is a positive corelation between wind velocity and voltage produced. The wind velocity beginto turn the turbines (cut-in speed) is 1.2m/s and the voltage generated is 2.666volt. The highest wind velocity record is 3.64m/s, with the voltage generated by 6.16volt

Judul: Komposisi Kimia Ikan Tuna Sirip Kuning (Thunnus albacares) Selama Penyimpanan Beku
Abstrak: Komposisi kimia yang terdapat pada ikan tuna sirip kuning (Thunnus albacares) lengkap dan bermanfaat bagi tubuh yang meliputi asam amino, asam lemak, taurin, vitamin, dan mineral. Penyimpanan beku merupakan salah satu cara untuk mempertahankan komposisi kimia. Penelitian ini bertujuan untuk menentukan pengaruh waktu penyimpanan beku terhadap komposisi kimia yang meliputi profil asam amino, asam lemak, taurin, vitamin, dan mineral pada ikan tuna sirip kuning. Pengamatan dilakukan selama enam bulan. Komposisi kimia sampel dianalisis dengan metode soxhlet dan kjeldahl, HPLC, dan kromatografi gas. Perubahan komposisi kimia selama penyimpanan beku 6 bulan pada ikan masih terjadi. Kandungan asam amino, asam lemak, taurin, dan vitamin mengalami penurunan selama penyimpanan. Penurunan rata-rata komposisi kimia selama penyimpanan beku yaitu taurin sebesar 73%, asam amino sebesar 74% dan asam lemak 24.48%. Penurunan tertinggi terjadi pada asam amino glutamat sebesar 75.64% dan asam lemak palmitat sebesar 19.9%. Waktu penyimpanan ikan tuna sirip kuning yang cukup baik yaitu selama tiga bulan.
