Abstract

Proses pendinginan dan pembekuan dapat mempertahankan kualitas dari bahan pangan yang mudah rusak (perishable food). Saat ini banyak muncul penelitian mengenai kotak pendingin berbahan campuran antara polyurethane dengan serat alami. Namun masih ditemukan kendala dimana pada setiap dinding kurang merata antara polyurethane dan serat alami. Pada penelitian ini dilakukan percobaan pembuatan panel insulasi dengan bahan campuran antara serat alami dan polyurethane dengan memperhatikan metode penyusunan kedua bahan. Serat alami menggunakan serat kapas yang memiliki nilai konduktivitas termal 0,015 W/mK. Pada penelitian ini, metode penyusunan kedua bahan dilakukan dengan pembuatan lapisan dari serat kapas maupun polyurethane. Penentuan ketebalan masing-masing lapisan dengan membandingkan menggunakan coolbox styrofoam. Pengujian pada coolbox insulasi dinding berbahan campuran serat kapas dan polyurethane dilakukan dengan menganalisa kinerja termal terhadap temperatur dan waktu pendinginan di ruang penyimpanan ikan. Pengujian dilakukan 2 kali, yang pertama dilakukan dengan beban es batu seberat 30% dari volume coolbox dan yang kedua menggunakan beban es batu 30% dari volume coolbox dan ikan 10% dari volume coolbox. Berdasarkan pengujian dan analisa data didapatkan nilai konduktivitas termal lembaran serat kapas 0,04638 W/mK dan ketebalan lapisan dinding yaitu lapisan serat kapas 1,68 cm, polyurethane 0,91 cm dan fiberglass (luar dan dalam) 0,2 cm sehingga total ketebalan dinding 2,99 cm dengan perbandingan persentase serat kapas dan polyurethane 50% : 50%. Pengujian coolbox menggunakan es batu 3,84 kg dan yang kedua es batu 3,84 kg dan 1,26 kg ikan. Pada percobaan 1 coolbox styrofoam lebih baik dalam mempertahankan suhu dibandingkan dengan coolbox campuran yaitu pada ΔT suhu udara dalam dengan suhu lingkungan di coolbox styrofoam 11,4°C sedangkan coolbox campuran 7,6°C. Percobaan 2 coolbox styrofoam lebih baik dari coolbox campuran yaitu ΔT pada coolbox styrofoam 15,2°C sedangkan coolbox campuran 9,9°C. Dan untuk suhu ikan, selama 24 jam pada kedua coolbox dapat mempertahankan suhu ikan dibawah 10°C

The cooling and freezing process can maintain the quality of perishable food. Currently, there is a lot of research on cooling boxes made from a mixture of polyurethane and natural fibers. However, there is still a problem where each wall is less evenly distributed between polyurethane and natural fibers. In this study, an experiment was made to make insulation panels with a mixture of natural fibers and polyurethane by paying attention to the method of preparation of the two materials. Natural fibers use cotton fibers that have a thermal conductivity value of 0.015 W/mK.
In this study, the method of preparing the two materials was carried out by making layers from cotton and polyurethane fibers. Determination of the thickness of each layer by comparing using styrofoam coolbox. Tests on wall insulation coolboxes made from a mixture of cotton fiber and polyurethane were carried out by analyzing the thermal performance of the cooling temperature and time in the fish storage room. The test was carried out 2 times, the first was carried out with an ice cube load weighing 30% of the coolbox volume and the second using an ice cube load of 30% of the coolbox volume and fish 10% of the coolbox volume. Based on testing and data analysis, the thermal conductivity value of cotton fiber sheets is 0.04638 W / mK and the thickness of the wall layer is 1.68 cm cotton fiber layer, 0.91 cm polyurethane and 0.2 cm fiberglass (outer and inner) so that the total wall thickness is 2.99 cm with a percentage ratio of cotton fiber and polyurethane 50% : 50%. The coolbox test used 3.84 kg ice cubes and the second 3.84 kg ice cubes and 1.26 kg fish. In experiment 1 styrofoam coolbox is better at maintaining temperature compared to mixed coolbox, namely at ΔT the air temperature is deep with the ambient temperature in the styrofoam coolbox 11.4 °C while the coolbox mixture is 7.6 °C. Experiment 2 styrofoam coolbox is better than mixed coolbox, namely ΔT on styrofoam coolbox 15.2°C while mixed coolbox is 9.9°C. And for fish temperature, for 24 hours in both coolboxes can maintain the fish temperature below 10 °C
