Wardhani, Anindya Kharisma (2019) Pengaruh Waktu Panen dan Lama Penyimpanan terhadap Karakteristik Fisikokimia Tomat (Lycopersicon esculentum Mill.). Sarjana thesis, Universitas Brawijaya.
Abstract
Tomat mengandung kandungan gizi yang bermanfaat untuk mengurangi timbulnya beberapa penyakit kronis. Namun, tanaman tomat merupakan komoditas pangan yang mudah rusak (perishable), sehingga perlu adanya penanganan panen dan pascapanen yang tepat. Buah yang dipanen terlalu matang akan menyebabkan daya simpan menjadi pendek. Umur simpan dari komoditas pertanian, terutama buah dipengaruhi oleh tingkat transpirasi dan respirasi yang masih terjadi setelah pemanenan. Tingkat transpirasi dan respirasi yang tinggi akan memberikan dampak pada menurunnya kualitas buah tomat. Tujuan penelitian ini untuk mengetahui pengaruh waktu panen dan lama penyimpanan terhadap kualitas buah tomat. Pengolahan data menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktor, faktor I yaitu waktu panen tomat (panen 1, panen 2, dan panen 3) dan faktor II yaitu lama penyimpanan (3, 6, dan 9 hari). Parameter yang diamati adalah susut bobot, tingkat kekerasan, total padatan terlarut, total asam, vitamin C, kandungan likopen dan betakaroten. Setiap perlakuan dilakukan pengulangan sebanyak 3 kali. Analisa data dilakukan dengan metode analisis sidik ragam (Anova) dan dilakukan uji lanjut dengan uji BNT 5% (Beda Nyata Terkecil). Berdasarkan hasil penelitian terdapat pengaruh waktu panen terhadap tingkat kekerasan, total padatan terlarut, total asam, vitamin C, dan betakaroten. Waktu panen ke-3 (85 HST) memiliki nilai tertinggi untuk seluruh parameter. Nilai tingkat kekerasan sebesar 17,31 N/cm2, total padatan terlarut sebesar 5,27ºBrix, total asam 0,09%, vitamin C sebesar 37,31 mg/gr, dan betakaroten 109,17 mg/gr. Terdapat juga pengaruh lama penyimpanan terhadap susut bobot, tingkat kekerasan, dan total asam. Hasil penelitian menunjukkan nilai tertinggi pada penyimpanan hari ke-9. Nilai susut bobot sebesar 0,04%, tingkat kekerasan 17,06 N/cm2, dan total asam 0,
English Abstract
Tomatoes contain lycopene which is useful for reducing the incidence of several chronic diseases. However, tomato plants are perishable food commodities, so it needs proper harvest and post-harvest handling. Harvested fruit that is too ripe will cause a short shelf life. The shelf life of agricultural commodities, especially fruit influenced by the level of transpiration and respiration that still occur after harvesting. High levels of transpiration and respiration have an impact on the declining quality of tomatoes. The purpose of this study was to determine the effect of harvest time and storage time on the quality of tomatoes. Data processing used a completely randomized design (CRD) with 2 factors, a factor I, the time of harvest of tomatoes (harvest 1, harvest 2, and harvest 3) and factor II, storage time (3, 6, and 9 days). The parameters observed were weight loss, hardness level, total dissolved solids, total acid, vitamin C, lycopene and beta-carotene content. Each treatment was repeated 3 times. Data analysis was performed using the analysis of variance (ANOVA) method and further tests were performed with the LSD test of 5% (Least Significant Difference). Based on the results of the study there was an influence of harvest time on the level of hardness, total dissolved solids, total acid, vitamin C, and betacarotene. The 3rd harvest time (85 HST) has the highest value for all parameters. The value of the hardness level is 17.31 N/cm2, the total dissolved solids are 5.27ºBrix, total acid is 0.09%, vitamin C is 37.31 mg/gr, and beta-carotene is 109.17 mg/gr. There was also an effect of storage time on weight loss, hardness level, and total acid. The results showed the highest value on 9th-day storage. The value of weight loss was 0.04%, hardness level was 17.06 N / cm2, and the total acid was 0.09%.
