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.

Abstrak: Indonesia is a maritime country, with a vast sea area, producing huge number of fish as the biggest sea commodity. The utilization of marine products, particularly fish, can be optimized with a good handling process. Catched fish should be stored at temperature 0ºC-5ºC to maintain its freshness. Unfortunately, many Indonesian fishermen are still using conventional methods to deal with the haul. For instance, a lot of ice are used to maintain the temperature and the addition of salt to prevent rotten fish. However, those methods will result in changes of quality and taste of the fish. Author created a model of portable solar-powered fish-chiller instrument. Solar power was selected as the alternative source of electric energy for this instrument, considering the fact that sunlight is the best resource which can be utilized when fishermen sail. The design of this instrument is divided into 3 parts: chiller design, energy source and energy source connector. The capacity is 40 liter with dimension : 80 cm of length, 70 cm of width and 90 cm of height. According to the trial, this instrument is able to generate a minimum temperature of -13.5º C and maximum temperature of -0.9º C in 90 minute. Based on the data obtained, this instrument can be used as the fish chiller to maintain the freshness of the fish.
