Abstract: Anggur merupakan buah yang rentan mengalami kerusakan dan memiliki masa simpan yang relatif pendek. Teknologi penanganan pascapanen yang tepat diperlukan guna menjaga mutu produk dan memperpanjang masa simpan buah anggur. Penelitian ini bertujuan mengkaji pengaruh pelilinan dan suhu penyimpanan untuk mempertahankan mutu buah anggur dan menentukan umur simpan buah anggur pada berbagai konsentrasi pelilinan dan suhu penyimpanan pendekatan Arrhenius. Bahan yang digunakan dalam peneilitian ini adalah buah anggur varietas Julian berukuran 26-28 mm x 40-42 mm dengan bobot 7-8,5 g per buah yang diperoleh dari petani di kebun anggur Anggola Kabupaten Bogor. Pelilinan menggunakan lilin lebah dengan bahan tambahan berupa akuades, asam oleat, dan trietanolamin. Buah anggur dicelupkan pada larutan lilin dengan konsentrasi 4% dan 12% dan sebagai kontrol adalah buah anggur tanpa pelilinan. Masing-masing kelompok buah anggur kemudian disimpan pada suhu 0, 15 dan 25 oC. Parameter yang diamati selama penyimpanan adalah kadar air, susut bobot, total padatan terlarut, dan kekerasan buah anggur. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) Faktorial dengan dua faktor, yaitu konsentrasi lilin (0%, 4% dan 12%) dan suhu penyimpanan (0 oC, 15 oC dan 25 oC). Data diolah menggunakan analisis sidik ragam (ANOVA) dan uji lanjut Duncan. Perubahan mutu pada berbagai suhu penyimpanan digunakan untuk menduga umur simpan buah menggunakan metode ASLT. Hasil penelitian menunjukkan bahwa pelilinan dan suhu penyimpanan berpengaruh terhadap penurunan mutu buah. Hasil terbaik adalah pada pelilinan 12% dan suhu penyimpanan 0 oC mampu memperpanjang masa simpan dari 16 hari menjadi 21 hari. Hasil pendugaan umur simpan buah anggur menggunakan metode ASLT adalah 21 hari pada konsentrasi pelilinan 12% dengan suhu penyimpanan 0 oC berdasarkan parameter mutu total padatan terlarut.
Grapes are a fruit that is susceptible to damage and has a relatively short shelf life. Appropriate postharvest handling technology is needed to maintain product quality and extend the shelf life of grapes. This study aims to examine the effect of coating and storage temperature to maintain the quality of grapes and determine the shelf life of grapes at various coating concentrations and storage temperatures using the Arrhenius approach. The materials used in this study were grapes of the Julian variety measuring 26-28 mm x 40-42 mm with a weight of 7-8.5 g per fruit obtained from farmers in the Anggola vineyard, Bogor Regency. Coating using beeswax with additional ingredients in the form of distilled water, oleic acid, and triethanolamine. The grapes were dipped in a coating solution with a concentration of 4% and 12% and the grapes without coating were used as a control. Each group of grapes was then stored at 0, 15 and 25 oC. Parameters observed during storage were moisture content, weight loss, total dissolved solids, and hardness of grapes. The experimental design used was a completely randomized design (CRD) factorial with two factors, namely coating concentration (0%, 4% and 12%) and storage temperature (0 oC, 15 oC and 25 oC). Data were processed using analysis of variance (ANOVA) and Duncan's further test. Quality changes at various storage temperatures are used to estimate the shelf life of fruit using the ASLT method. The results showed that coating and storage temperature had an effect on decreasing fruit quality. The best results were at 12% coating and 0 oC storage temperature which extended the shelf life from 16 days to 21 days. The results of estimating the shelf life of grapes using the ASLT method were 21 days at a coating concentration of 12% with a storage temperature of 0 oC based on the total dissolved solids quality parameter.
