Abstract

The purpose of this research was to determine the effects of various fermentation facilitators and the drying temperature in producing quality cocoa beans. It also aimed to understand the effects of the addition of fermentation facilitators and drying temperature on the quality of cocoa beans as well as the interactions between the two studied factors. The research was performed at the Service Technical Implementation Unit (UPTD) of the Saree Horticulture Seed Center, Lembah Seulawah District, Aceh Besar Regency, and the Plant Pathology and Crop Analysis Laboratories of the Faculty of Agriculture of Syiah Kuala University. The study was carried out from August to October 2015. This research was conducted using a Randomized Block Design (RBD) of a 3 x 3 factorial design with three repetitions. The tested factors were: Fermentation Factor (F), with levels consisted of = F0: Natural Fermentation, F1: Fermentation using Saccharomyces cerivisiae at day 0, F2: Fermentation using Saccharomyces cerivisiae at day 1, and Drying Temperature Factor (T), with levels consisted of = T0: Sun Drying, T1: Oven Drying at 50­­­oC, T2: Oven Drying at 60oC. The observed variables were: acidity level (pH), water content and fat content. The fermentation facilitators affected the speed of fermentation and quality of cocoa beans. The drying temperature affected the quality of cocoa beans. The interaction between fermentation facilitators and drying temperature can decrease the beans’ water content, acid total, and increase their fat content.

Abstract

Buah Tomat (Lycopersicum esculentum Mill.) merupakan merupakan salah satu jenis tanaman hortikultura. Tomat sebagai komoditas hortikultura pada umumnya memiliki sifat mudah rusak sehingga penanganan pascapanen buah tomat yang tidak tepat dapat mengakibatkan penurunan mutu buah. Edible coating merupakan suatu metode yang digunakan untuk memperpanjang umur simpan dan mempertahankan mutu dari buah-buahan pada suhu ruang. Edible coating adalah lapisan tipis yang bertujuan untuk memberikan penahanan yang selektif terhadap perpindahan massa dan atau sebagai pembawa aditif serta untuk meningkatkan penanganan suatu makanan. Tujuan penelitian adalah untuk mengetahui konsentrasi dan lama perendaman ekstrak lidah buaya terhadap kandungan vitamin C dan organoleptik pada buah tomat serta mengetahui perlakuan terbaik antara tingkat konsentrasi dan lama perendaman terhadap kandungan vitamin C dan organoletik. Metode yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap (RAL) dengan 2 faktor yaitu perlakuan konsentrasi (K) yang terdiri dari 4 taraf antara lain 100% ekstrak lidah buaya, 75% ekstrak lidah buaya + 25% air, 50% ekstrak lidah buaya + 50% air, dan 25% ekstrak lidah buaya + 75% air dan lama perendaman (P) yang terdiri dari 3 taraf antara lain 15 menit, 30 menit dan 45 menit. Pengamatan dilakukan pada 0, 4, 8, 12, dan 16 hari setelah perlakuan. Masing-masing perlakuan diulang sebanyak tiga kali. Analisa keragaman hasil dilakukan dengan analisa ANOVA, dilanjutkan dengan uji BNT 5% untuk melihat perbedaan antar perlakuan. Hasil yang diperoleh dari penelitian ini adalah umur simpan buah tomat berpengaruh terhadap kandungan vitamin C dan Organoleptik. Hasil organoleptik terhadap buah tomat berpengaruh pada parameter warna dan tekstur sampai penyimpanan 16 hari. Perlakuan terbaik pada kandungan vitamin C dan organoleptik terhadap buah tomat yaitu perlakuan konsentrasi 100% dan lama perendaman selama 45 menit.
