Abstract

Increasing marine resources is one of the main programs of the current government. To support this, it is necessary to increase human resources in coastal areas. One of the very basic and important things is basic knowledge about the cooling process of fish catch on board. The use of ice cubes as a cooling medium for fish that is less than optimal is one of the big problems experienced by fishermen. Their lack of knowledge about the types of refrigerants other than ice cubes results in a loss of fresh catch that reaches consumers as a result they have to spend more money on the cost of buying ice blocks every time they make a voyage. For this reason, in this service program that will be carried out, the community will be guided on the manufacture and treatment of ice gel/packs as a substitute for ice cubes, which is much more effective to use ice gel/packs as a cooling medium which is expected to be able to help fishermen to maintain the quality of their produce. catch and optimize the capacity of the hold space to accommodate more abundant catches to the buying and selling process. This activity will increase the level of productivity and welfare of the fishing community, especially in the place where this activity is carried out, namely in Ampekale Village, Bontoa District, Maros Regency.

Abstract

The use of engine power in the ship propulsion system makes it easier for traditional fishermen to carry out their activities. On the other hand, modern technology requires basic knowledge to be operated and maintained properly and according to procedures. Incorrect installation of one machine component will of course have an impact on other components which will very detrimental to fishermen, as experienced by fishermen in Ammani Village, Pinrang Regency. The power transmission system from the propulsion engine to the ship's propeller via the shaft is an important component that must be considered. Sufficient understanding of this problem will have a very good impact on its use and service life. Selection and installation of an inappropriate transmission system will result in large vibrations, broken shafts, wear of bearings and clutches and can even damage the drive engine which is the most expensive component in the transmission system. In this activity, training was held on one of the problems often experienced by fishermen in Ammani Village, Pinrang Regency, namely propeller imbalance after undergoing a repair process. The series of activities consisted of presenting material about machinery transmission systems, propeller characteristics and propeller balancing demonstrations. Of the 20 (twenty) participants, there was an increase of 25% who answered understanding of power transmission systems, 20% increased in understanding of propeller characteristics and 45% increased in understanding of propeller static balancing methods after the activity was completed. By holding this activity, it is hoped that the fishermen participating in the training will understand and be able to carry out the static balancing process independently on the propeller before installing it. This will certainly provide a slight reduction in transmission system maintenance costs because the service life of the components is relatively longer.

Abstract

Palka ikan merupakan tempat menyimpan dan menjaga kesegaran hasil tangkapan yang penempatannya secara permanen maupun yang masih bisa diangkat dan diturunkan dari kapal. Berdasarkan hasil wawancara dan survei langsung terhadap beberapa nelayan di Makassar, khususnya nelayan kapal katinting. Sebagian besar masih memanfaatkan kotak styrofoam yang biasanya diisi dengan es batu untuk mempertahankan kesegaran dan mutu ikan hingga sampai ke tangan konsumen. Namun metode pendinginan tersebut dapat mengurangi kapasitas ruang muat palka. Untuk itu diperlukan sebuah sistem pendingin yang optimal dan juga ramah terhadap lingkungan. Sistem pendingin palka ikan berbasis energi surya merupakan opsi yang tepat untuk digunakan. Penggunaan dan pengaplikasiannya yang cenderung lebih mudah dan sangat memungkinkan diterapkan pada perahu nelayan. Dengan memanfaatkan sistem pendingin tersebut tentunya pada dinding palka harus dilapisi dengan material isolator yang mampu mempertahankan suhu yang diinginkan di dalam ruang palka. Maka pada penelitian ini dilakukan perhitungan beban pendingin dengan Cooling Load Temperature Difference (CLTD) dan menganalisa perbandingan penggunaan material insulasi palka yakni polystyrene dan polyurethane menggunakan metode Computational Fluid Dynamics (CFD). Palka dengan lapisan insulasi polystyrene (fiberglass 3 mm + polystyrene 1 cm + fiberglass 2 cm) dengan perhitungan diperoleh beban panas (Q) sebesar 92 W dan heat flux 47,339 W/m2, dari hasil simulasi diperoleh temperatur operasi ruang palka 2,073℃, heat flux 46,163 W/m2, dan persentase penyimpangan antara hitungan dengan simulasi sebesar -2,484%. Palka dengan lapisan insulasi polyurethane (fiberglass 3 mm + polyurethane 1 cm + fiberglass 2 cm) dengan perhitungan diperoleh beban panas (Q) sebesar 84 W dan heat flux 43,378 W/m2, dari hasil simulasi diperoleh temperatur operasi ruang palka 2℃, heat flux 42,593 W/m2, dan persentase penyimpangan antara hitungan dengan simulasi sebesar -1,808%, dengan beban panas, heat flux, dan persentase penyimpangan yang lebih rendah didapatkan pada palka dengan material insulasi polyurethane, sehingga material insulasi yang tepat untuk diaplikasikan pada palka ikan Katinting yaitu polyurethane.
