Abstract

Untuk mengatasi peningkatan konsumsi energi, penggunaan energi secara efektif dan pengembangan sumber energi terbarukan menjadi fokus utama. Insulasi adalah salah satu cara untuk menghemat energi yang sudah diterapkan pada reefer container. Penelitian ini berfokus pada pengembangan sistem insulasi pada prototipe reefer container dengan menggunakan bahan serat kapas dan polyurethane. Metodologi penelitian ini dilakukan dengan membuat perancangan desain struktur dinding komposit dengan bahan campuran serat kapas dan polyurethane, melaksanakan modifikasi desain struktur dinding prototipe dengan komposisi campuran serat kapas dan polyurethane 50%:50% dan melakukan pengujian kinerja untuk menganalisa kinerja termal terhadap suhu dan waktu pada prototipe. Pengujian termal dilakukan dengan beban produk seberat 20% dari total massa kargo dan tanpa beban produk pada prototipe reefer container ½ ton berdinding komposit polyurethane murni dan berdinding komposit campuran serat kapas dan polyurethane. Berdasarkan pengujian dan analisa data, didapatkan ketebalan dinding komposit campuran yang mana ketebalan serat kapas sebesar 0,696 cm dan ketebalan polyurethane foam sebesar 3,5cm. Dari percobaan yang dilakukan diketahui bahwa dalam insulasi pada dinding komposit polyurethane murni suhu udara dalam mengalami kenaikan suhu udara sekitar 2 jam tiap derajatnya ketika berisi muatan, dan saat tanpa muatan. Pada dinding komposit bahan campuran suhu udara dalam mengalami kenaikan suhu udara sekitar 54 menit tiap derajatnya ketika berisi muatan dan saat tanpa muatan mengalami kenaikan suhu udara sekitar 46 menit tiap derajatnya. Hal ini menunjukkan bahwa sistem dinding insulasi komposit polyurethane murni memiliki kinerja lebih baik dalam mempertahankan suhu udara dingin dibanding dinding insulasi komposit campuran 50% serat kapas dan 50% polyurethane.

To overcome the increasing energy consumption, the effective use of energy and the development of renewable energy sources have become the primary focus. Insulation is one of the methods applied to conserve energy in reefer containers. This study focuses on developing an insulation system for a prototype reefer container using cotton fiber and polyurethane as the materials. The research methodology involves designing a composite wall structure using a mixture of cotton fiber and polyurethane, implementing modifications to the prototype wall structure with a 50% cotton fiber and 50% polyurethane composition, and conducting performance testing to analyze the thermal performance concerning temperature and time on the prototype. The thermal testing is carried out with a product load weighing 20% of the total cargo mass and without any product load on the prototype reefer containers, one made of pure polyurethane composite and the other made of a composite mixture of cotton fiber and polyurethane. Based on the testing and data analysis, it was found that the composite mixture's thickness consists of 0.696 cm of cotton fiber and 3.5 cm of polyurethane foam. The experiments showed that in the insulation of the pure polyurethane composite wall, the interior air temperature increases approximately 2 hours per degree when loaded with cargo and when empty. For the composite wall made of the mixed material, the interior air temperature increases about 54 minutes per degree when loaded with cargo and about 46 minutes per degree when empty. This indicates that the pure polyurethane composite insulation system performs better in maintaining a cold interior air temperature compared to the composite mixture of 50% cotton fiber and 50% polyurethane.
