Judul: Kandungan Gizi Buah Tin (Ficus carica L.) Produksi Indonesia
Abstrak: The aim of this study was to identify the nutritional content of fig fruits including macro and micro nutrient, antioxidant, phytochemical, as well as the panelis preferenees. Three varieties of figs from “Sentra Tin” Bekasi were used in this study i.e Green Yordan, Purple, and Negronne. The macro nutrient content of figs were as follow (% wb) moisture 86.34, 80.57, 82.10, ash 0.75, 0.86, 0.96, protein 1.45, 1.48, 1.91, fat 0.14, 0.22, 0.56, crude fiber 2.30, 2.18, 2.77, total carbohydrate 9.01, 14.67, 11.70, and reducing sugar 1.70, 3.00, and 4.66 respectively. The micronutrient content were as follow (mg/100g) sodium content 2.11, potassium content 854.05, calcium content 104.79, and zink 1.10 respectively. Total phenolic content were as follow (mgGAE/100g) 20.28, 10.38, 28.72 respectively. The three fruits content antocyanin were as (μg/g) 61.48, 59.93, 156.29. Antioxidant of Green Yordan and Negronne are very active (mg) 29.75 and 39.75 respectively. Green Yordan is the most prefered by the panelis with percentage of acceptability 93.33%. The nutritional content of fig cultivated in Indonesia were compared with the production in other country or origin.

Judul: Analisis kapasitas Antioksidan dan kandungan total Fenol pada buah
Abstrak: Buah merupakan salah satu potensi sumber antioksidan. Penelitian mengenai kapasitas antioksidan dan kandungan total fenol buah dari Indonesia masih sangat terbatas. Tujuan dari penelitian ini adalah untuk menganalisis kapasitas antioksidan dan kandungan total fenol dari berbagai jenis buah yang diperjualbelikan dan dikonsumsi di Indonesia. Tiga puluh jenis buah dipilih secara purposif di pasar Anyar, Bogor. Kapasitas antioksidan buah dianalisis menggunakan metode DPPH dan total fenol dianalisis menggunakan metode Folin-Ciocalteau. Hasil menunjukkan bahwa asam jawa memiliki kapasitas antioksidan tertinggi dengan 76.15±0.09 mg AEAC/100 g. Pisang mas memiliki kapasitas antioksidan terendah dengan 1.29±0.14 mg AEAC/100 g. Buah berwarna tua memiliki rata-rata kapasitas antioksidan lebih tinggi dibandingkan dengan buah berwarna muda. Markisa memiliki kandungan total fenol tertinggi dengan 3.25±1.70 mg TAE/100 g, dan pisang kepok terendah dengan 0.12±0.29 mg TAE/100 g. Penelitian ini juga menunjukkan adanya korelasi positif antara kapasitas antioksidan dan kandungan total fenol (p<0.05; r=0.545, Fruit is one of potential sources of antioxidant. Very limited studies have been done in determining the antioxidant capacity and phenolic content of fruits of Indonesia. The objective of this study was to analyze the antioxidant capacity and phenolic content of various types of fruits is traded and consumed in Indonesia. Thirty kind of fruits were selected purposively in Anyar traditional market of Bogor. The antioxidant capacity of the fruits was evaluated by applying DPPH method and total phenolic content was analized by applying the Folin- Ciocalteau method. The results showed that tamarind has the highest antioxidant capacity of 76.15±0.09 mg AEAC/100 g Mas banana is the lowest antioxidant capacity of 1.29±0.14 mg AEAC/100 g. Dark-colored fruits have a higher antioxidant capacity than the light-colored fruit. Passion fruit has the highest total phenolic content of 3.25±1.70 mg TAE/100 g and kepok banana has the lowest total phenolic content of 0.12±0.29 mg TAE/100 g. This study also showed that the positive correlation between antioxidant capacity and total phenolic content (p<0.05; r=0.545).
