Abstract

Tomat (Solanum Lycopersicum) merupakan salah satu sayuran serta buah-buahan yang di gemari oleh masyarakat di Indonesia. Masa simpan tomat saat sudah matang memerah hanya membutuhkan waktu 1-2 hari ditempat terbuka hingga membusuk. Oleh sebab itu untuk mencegah pembusukan pada tomat dapat dilakukan cara pengawetan. Metode pengawetan buah yang paling baik adalah pengawetan alami secara biologis dengan larutan ecoenzym. Salah satu bahan alami untuk mengawetkan tomat adalah dengan memanfaatkan ecoenzym dari limbah organik kulit mentimun. Sehingga tujuan dari penelitian ini adalah untuk mengetahui persentase volume produksi ecoenzym dengan variasi gula, perubahan tekstur pengawetan tomat setelah di semprot ecoenzym, dan perubahan aroma pengawetan tomat setelah di semprot ecoenzym. Ecoenzym yang menggunakan gula merah menghasilkan cairan ecoenzym dengan jumlah lebih banyak yaitu 3,2 liter dengan persentase volume ecoenzym adalah 95%. Ecoenzym yang menggunakan gula pasir menghasilkan cairan ecoenzym dengan jumlah volume lebih sedikit yaitu 2 liter dengan persentase volume ecoenzym adalah 61% Ecoenzym dari limbah kulit mentimun terbukti dapat menghambat pertumbuhan mikroorganisme penyebab kebusukan pada tomat. Pada pengawetan tomat yang disemprot menggunakan cairan ecoenzym gula merah mengalami kemunduran mutu pada hari ke-7, tomat yang disemprot cairan ecoenzym gula pasir mengalami kemunduran mutu pada hari ke-5, dan tomat yang tidak disemprot cairan ecoenzym mengalami kemunduran mutu pada hari ke-4. Kemunduran mutu tomat ditandai dengan tekstur empuk, lembek dan berair, serta aroma masam dan menyengat pada tomat.Kata Kunci: Tomat, Ecoenzym, Limbah organik

Abstract

Cabbage is a vegetable that thrives in Indonesia. This type of vegetable is a vegetable that is not durable and prone to decay and produces organic waste waste from cabbage leaves which causes unpleasant odors that can pollute the environment. Waste from cabbage can be used as a base for making eco-enzyme fluids. Eco-enzyme liquid is a liquid produced from the fermentation of organic waste, this liquid has a reddish brown color, has a fresh and strong odor. This eco-enzyme contains propionate acid which can inhibit microorganisms in the decay process so that it can be used as a natural preservative. The purpose of this study was to analyze the effect of adding eco-enzyme solutions on tomato fruit preservation and to find out on what day of the tomatoes decomposed and changes in tomatoes that were not sprayed with eco-enzymes. This type of research is an experimental study using 2 types of substrate variations, namely by using the basic ingredients of making eco-enzyme liquid using palm sugar with cabbage waste (Variable 1) and sugar with cabbage waste (Variable 2). Based on the research results, it was found that the eco-enzyme liquid, palm sugar substrate was 60% and granulated sugar substrate was 40% and the most effective eco-enzyme liquid for natural preservatives in tomatoes is eco-enzyme using palm sugar.
