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: 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: Effects of Alcohol Consumption on Spatial Memory Performance and Neuron Complexity
Abstrak: Alcoholic beverages have always been a common drink all around the globe. The ethanol that is contained inside these alcoholic beverages have been known to have various negative side effects to the brain if consumed excessively. Other articles have claimed a certain moderate amount of alcohol consumption could have beneficial effects on the brain, but no exact concentration limit of consumption has been elaborated to cause damage in the hippocampal area. The objective of this research is examining the effects of alcohol towards neuron complexity and spatial memory performance. Four groups of mice were used as test subjects and were given the solution pre-orally. The first group is the control group which is given water, the second group was given 5% alcohol, the third group was given 15% alcohol, and the fourth group was given commercially sold alcoholic beverage. The mice were given said solutions in the span of 30 days. Spatial memory performance is observed by how a mice scores inside a Y-maze in the span of 5 minutes after 30 days of treatment. Neuron complexity is determined by the number of intersections of dendrites and the maximum angle of neurons inside the Dentate Gyrus (DG) and Cornu Ammonis (CA) region of the hippocampus which is observed by Golgi-Cox staining, photographed with optilab and then analyzed using the ImageJ application. alcohol consumption does not have any significant effect on spatial memory performance nor neuron complexity in the hippocampal area. These findings are not significantly different than the control group, possibly because the treatment is not chronic enough to trigger a significant physiological change.
