Tomat (Solanum lycopersicum L.) merupakan tanaman hortikultura yang banyak dibudidayakan. Tomat mudah mengalami kerusakan, hal tersebut menyebabkan kerugian pascapanen sebelum produk dikonsumsi. Kerugian pascapanen karena penyimpanan yang tidak benar mencapai 30-40%. Faktor lingkungan yang berperan penting dalam kualitas pascapanen buah dan sayuran adalah suhu dan kelembaban. Untuk penanganan pascapanen diperlukan penerapan sistem manajemen pascapanen yang hemat biaya dan ramah lingkungan untuk menjaga kualitas, memperpanjang umur simpan dan mengurangi kerugian pascapanen yang mudah rusak. 
Sistem pendingin evaporatif dikenal ekonomis dan teknologi yang efisien untuk menurunkan suhu, meningkatkan kelembaban relatif dan juga meningkatkan umur simpan hasil hortikultura. Penelitian ini bertujuan untuk: 1) Mengetahui kondisi perlakuan terbaik untuk mempertahankan mutu tomat selama penyimpanan pada pendingin evaporatif. 2) Mengetahui pengaruh laju aliran dan jenis cooling pad terhadap perubahan sifat fisik tomat (Solanum lycopersicum L.) selama penyimpanan pada pendingin evaporatif. 3) Menganalisis perubahan sifat fisik tomat (Solanum lycopersicum L.) selama penyimpanan pada suhu pendingin evaporatif dan suhu ruang.
Hasil penelitian diperoleh kesimpulan kondisi terbaik penyimpanan pendingin evaporatif pada perlakuan cooling pad spons dengan laju aliran 6 liter/menit (C1L2) dengan hasil evektifitas pendinginan 66,67%. Mengetahui pengaruh jenis cooling pad dan laju aliran pada perlakuan C1L2 (cooling pads spons dan laju aliran 6 liter/menit) dapat menyimpan tomat selama 12 hari. Kombinasi cooling pad dan laju aliran pada perlakuan C1L2 berpengaruh terhadap umur simpan tomat selama penyimpanan. Perlakuan kombinasi C2L1 (cooling pads serabut dan laju aliran 4 liter/menit) terdapat perbedaan nyata pada tingkat kemerahan a(+). Kombinasi C2L2 (cooling pads serabut dan laju aliran 6 liter/menit) terdapat perbedaan nyata pada perubahan tingkat kekuningan b(+) selama penyimpanan. Kombinasi C1L2 (cooling pads spons dan laju aliran 6 liter/menit) terdapat perubahan nyata pada perubahan kadar brix selama penyimpanan.

Tomato (solanum lycopersicum L.) is a horticultural crop that is widely cultivated. Tomatoes are easily damaged, this causes post-harvest losses before the product is consumed. Postharvest losses due to improper storage reach 30-40%. Environmental factors that play an important role in the postharvest quality of fruit and vegetables are temperature and humidity. For post-harvest handling, it is necessary to implement a post-harvest management system that is cost-effective and environmentally friendly to maintain quality, extend shelf life and reduce post-harvest losses that are easily damaged.
Evaporative cooling systems are known to be economical and efficient technology to lower temperature, increase relative humidity and also increase shelf life of horticultural produce. This study aims to: 1) Determine the best treatment conditions to maintain tomato quality during storage in an evaporative cooler. 2) Determine the effect of flow rate and type of cooling pad on changes in physical properties of tomatoes (Solanum lycopersicum L.) during storage in an evaporative cooler. 3) Analyzing changes in the physical properties of tomatoes (Solanum lycopersicum L.) during storage at evaporative cooling and room temperature.
The results of the study concluded that the best conditions for evaporative cooling storage were in the sponge cooling pad treatment with a flow rate of 6 liter/minute (C1L2) with a cooling effectiveness of 66.67%. Knowing the effect of the type of cooling pad and flow rate on the C1L2 treatment (cooling pads sponge and flow rate of 6 liters/minute) can store tomatoes for 12 days. The combination of cooling pad and flow rate in C1L2 treatment affects the shelf life of tomatoes during storage. The combination treatment of C2L1 (cooling pads fiber and flow rate of 4 liters/minute) showed a significant difference in the level of redness a(+). The combination of C2L2 (cooling pads of fibers and flow rate of 6 liters/minute) showed a significant difference in changes in the level of b(+) yellowness during storage. The combination of C1L2 (cooling pads sponge and flow rate of 6 liters/minute) showed significant changes in changes in brix content during storage.
