Abstract
Sumber daya bidang kelautan Indonesia yang menjadi mata pencaharian pokok bagi nelayan adalah ikan. Kesegaran ikan merupakan faktor utama dalam menentukan harga jualnya. Untuk menjaga kesegaran ikan, nelayan tradisional umumnya menggunakan metode pendinginan ikan dengan sistem pendingin es basah yang diletakkan dalam coolbox. Nelayan tradisional dimana waktu melautnya one day fishing sangat tergantung pada lama waktu coolbox mempertahankan temperaturnya. Serbuk kayu dan karung goni banyak tersedia di lingkungan sekitar dapat dimanfaatkan sebagai insulasi coolbox. Penelitian ini dilakukan modifikasi coolbox berbahan insulasi serbuk kayu dan karung goni (kain goni). Tujuan dari penelitian ini untuk mengetahui pengaruh insulasi serbuk kayu dan kain goni terhadap temperatur dan waktu pendinginan yang kemudian dibandingkan dengan coolbox berinsulasi styrofoam. Percobaan dilakukan dari pengujian komposit serbuk kayu dengan perekat semen putih. Pengujian meliputi massa jenis, kekuatan bending, dan konduktivitas termal. Parameter yang paling berpengaruh sebagai bahan insulasi yaitu konduktivitas termal terbaik pada perbandingan 1 : 1 yaitu 0,821 W/mK. Pada percobaan yang telah dilakukan dengan 3 kg es balok didapatkan bahwa total waktu pendinginan sampai suhu 25 °C coolbox modifikasi terbaik (coolbox serbuk kayu + kain goni) yaitu 20 jam 30 menit dengan suhu terendah 16,6 °C, tetapi masih kalah dengan coolbox styrofoam dengan suhu terendah 10,6 °C dengan lama waktu pendinginan lebih dari 24 jam. Sehingga dapat disimpulkan komposit serbuk kayu dan semen putih kurang efektif digunakan sebagai bahan insulasi. Sedangkan kain goni baik digunakan sebagai bahan insulasi.

The resources of the Indonesian marine sector to be the main livelihood for fishermen are fish. Freshness of fish is the main factor in determining the selling price. To keep the freshness of the fish, traditional fishermen generally use the method of cooling the fish with a wet ice cooling system that is placed in the coolbox. Traditional fishermen where the time of one day fishing is very dependent on the length of time coolbox to maintain its temperature. Sawdust and gunny sack widely available in the surrounding environment can be utilized as coolbox insulation. This study was modified coolbox made from insulation of sawdust and gunny sack (gunny). The purpose of this study aims to determine the effect of insulation of sawdust and gunny against the temperature and cooling time which is then compared with styrofoam-insulated coolbox. The experiments were carried out from testing of sawdust composites with white cement adhesives. Tests include density, bending strenght, and thermal conductivity. The most influential parameter as the insulation material is the best thermal conductivity in the 1 : 1 ratio of 0,821 W/mK. In the experiments that had been done with 3 kg of ice beams it was found that the total cooling time up to 25 °C was the best modified coolbox (sawdust + gunny coolbox) which was 20 hours 30 minutes with the lowest temperature of 16.6 °C, but still inferior to coolbox styrofoam with the lowest temperature of 10.6 °C with a cooling time of more than 24 hours. So it can be concluded composite sawdust and white cement less effective use as insulation material. While gunny is good used as an insulation material.
