Judul: Angin sebagai Sumber Energi Alternatif pada Mesin Pendingin Skala Kecil
Abstrak: The cooling process is one of the handlers catches a very needed by fishermen in maintaining the quality of the catch. The process of cooling or freezing as long as this is done by most fishermen still use the ice and still highly dependent on the availability of the ice. On some fishing vessel refrigeration technology is implemented, but electrical energy needed is still mostly supplied from use of motor fuels that are less environmentally friendly. This gave rise to the idea to find alternative sources of energy in order to obtain some solution of the problem. The purpose of this research is: (1) find out the minimum wind speed needed to fill the electric power to the storage system; (2) know the length of time it takes to do the charging system into storage until it is full; and (3) find out the time used to spend the stored energy and temperature are achieved. The results of this research show that the minimum wind speed needed to play the wind turbines which amounted to 16.2 km/h and produces turbine rotation speed of 41.2 rpm. The time it takes to charge the accumulator 45 Ah to the brim with an average wind speed of 17.5 km/h, the average turbine rotation speed of 53.6 rpm and average electric current generated 2.4 ampere is 18 hours 45 minutes. The time it takes to reduce the accumulator voltage to 6 volts is 2 hours 1 minute 59 seconds and generate temperatures of 3.5 °C. Experimental results show that the wind can be used as an alternative source of energy on a small scale refrigeration designed.

Judul: Pemanfaatan Turbin Ventilator sebagai Sumber Tenaga Listrik
Abstrak: The increasing demand for electrical energy in Indonesia becomes one of the national problems. The wind energy which is relatively abundant at some places in Indonesia could become an alternative energy resources to fill those needs. Wind energy is converted into mechanical energy by wind turbine. In wind turbine, the energy of motion is converted into electrical energy by a generator. Ventilator turbine is capable to rotate 24 hours and mostly used as suction fan in factories roof, warehouses, gyms, etc. This research is aimed to use the ventilator turbine to produce electricity. This ventilator wind turbine consists of motorcycle where the number of coils was varied for each data. The number of coils used are varied as 3200, 4000, 4800 and 5600. The average electrical voltage generated from the 3200, 4000, 4800 and 5600 coil at high speed was 4.62 Volt, 6.23 Volt, 6.99 Volt and 8.50 Volt while the average electrical voltage generated at medium speed is 3.49 Volt, 4.69 Volt, 4.45 Volt and 6.00 Volt.

Judul: Nematoda parasit pada intestinal satwa primata
Abstrak: Penyakit parasit cacing pada saluran intestinal satwa primata sering disebabkan oleh Strongyloides spp. dan Oesophagostomum sp. yang masing-masing menyebabkan terja- dinya strongyloidiasis dan oesophagostomiasis. Dari ber- bagai koloni satwa primata ditemukan berbagai parasit nematoda intestinal seperti Enterobius sp., Trichuris sp., Physaloptera sp. dan Streptopharagus sp. Namun yang paling sering ditemukan adalah Strongyloides spp. dan Oeso- phagostomum sp. Kedua jenis cacing ini dapat dibedakan dari hasil pemeriksaan telur cacing pada tinja segar sat- wa primata terinfeksi dan stadium larva atau cacing dewa- sa pada pemeriksaan patologis-anatomis. Kepekaan beberapa golongan satwa primata terhadap infeksi Strongyloides spp. dan Oesophagostomum sp. berbeda satu sama lain. Grup Old World Monkey (OWM) umumnya sangat peka terhadap infeksi kedua jenis cacing tersebut, sedangkan grup New World Monkey, Apes dan Prossimian relatif lebih resisten. Kasus strongyloidiasis dan oesophagostomiasis banyak ditemukan pada satwa primata yang baru ditangkap dari hutan sebagai habitat asal. Tampaknya penularan yang terjadi pada satwa primata didapatkan secara alami atau didapatkan dari kontak dengan manusia selama penangkapan, transfortasi, ataupun kontaminasi silang di tempat penam- pungan. Penularan strongyloidiasis dan oesophagostomi- asis terutama terjadi melalui kontaminasi tinja yang ne- ngandung telur cacing atau larva infektif, infeksi silang dari satwa primata lainnya, atau melalui peralatan ter- kontaminasi misalnya tempat makanan dan minuman tercemar…dst
