Abstract

A research to determine the effects of liquid organic fertilizer as a decomposer and nutrition source on the growth of rice plant (Oriza sativa L.). This research was conducted in Wirokerten, Botokenceng, Bantul, Yogyakarta. Field experiment was  arranged using Randomized Completely Block Design with 2 factors and three replications. The first factor was liquid organic fertilizer, consist of liquid organic fertilizer and witout liquid organic fertilizer. The second factor was the doses of SRI, consist of 25% SRI, 50% SRI, 75% SRI and 100% SRI (urea fertilizer 350 kg/ha, 150 kg/ha of SP-36 fertilizer and 150 kg/ha of KCl fertilizer). The result showed that the liquid organic fertilizer with dose 10 l/ha macro fertilizer and 5 l/ha micro fertilizer were not significantly increased the growth and yield of rice plant. Liquid organic fertilizer with dose 75% SRI was significantly increased the leaf number than dose of 25% and 100% SRI. Doses 25% and 100% of SRI with application the liquid organic fertilizer was significantly increased the weight of 1000 seeds. Doses of SRI was not significantly increased the rice yield per hectar.

Abstract

The fast-paced lifestyle of modern consumers warrants the need for a quick and minimally processed food. For fresh products, this means healthy fresh food, convenient, and microbiologically safe food items produced with environmentally friendly methods. In this research, antimicrobial effects of carboxymethyl cellulose based-edible film containing different concentrations of essential oils (0.7 % cinnamon, 0.7 % lemongrass, 3 % lemon, and 0.1 % betel, w/v) as antibacterial agents on fresh-cut apples cv. Manalagi were studied. Measurements of weight loss, total titratable acidity (TTA), reducing sugar, microbial growth and sensory quality were determined at 0, 3, 6, 9, 12 and 15 days of storage (4 ± 1 °C, 75 ± 10 % RH). The results of the research showed that the application of 0.7% lemongrass oil on 1 % CMC gave the best result in inhibiting the bacterial growth and prolong the storage life of fresh-cut apples cv. Manalagi. The incorporation of 0.7 % (w/v) lemongrass and lemon 3 % (w/v) in coating formulation maintained the sensory scores (aroma and appearance) of fresh-cut apples during nine days of storage.

Abstract

This  research was aimed to study  the influence  of   kinds of cooling and packing  on the storage life of sweetcorn in order to obtain the simple postharvest  technology and easy to practice.  The research was done during the February - March of 2005 in the Research Laboratory of Agriculture Faculty, Muhammadiyah  University of Yogyakarta.  The reducing sugar analysis was done in the  Agriculture Technology Faculty of Gadjah Mada University. The laboratory  experiment  was arranged  ini 2 x 3 factorial  completely  randomized design with three replications.  The cooling first factor  was refrigerated in refrigerator to be compared  to the hydro-cooling.  Meanwhile,  the polypropilene and polyethylene  packaging were tested and compared to the unpackaged one. The flavor; reducing sugar, water content, percentage  of nonconsumable  part of sweetcorn,   fresh  weight  of ears,  and organoleptic properties  were observed. The result showed  that there was no significantly   interaction between cooling and packaging on  the  storage life  and  quality  of  sweet corn. The  cooling treatment was significantly influenced the starch and reducing sugar level  as well as the packaging treatment. Refrigeration   storage could significantly keep   the  level   of reducing  sugar  to remain higher than the hydro-cooling, this treatment  was also   decreased the starch  content, decreased the proportion  of unconsumable  part,  and maintained   the flavor. The  polyethylene    packaging significantly keep the level  of reducing  sugar to remain higher and relatively maintained the flavor   than  the polypropilene packaging or  unpackaged, but  decreased  the portion  of unconsumable  part.

Abstract

Increasingly healthy lifestyles and advances in technology make people tend to prefer consuming fresh-cut fruits. Modified Atmosphere Packaging (MAP) contributes to extending shelf life and improving postharvest product quality. This study was aimed to determine the effects of argon-based MAP combined with heat treatment on the quality of the fresh-cut cavendish. There were four treatments examined, consisting of the combination of MAP with 73.70 % argon gas and heat treatment at 40 °C for 5 minutes (P1), heat treatment at 40 °C for five minutes (P2), MAP with 73.70 % argon gas (P3), and without treatment (P4). Each treatment consisted of three replications, and all experimental units were stored in a storage area at a temperature of 10 °C. The variables of fruit hardness, total titratable acidity, reducing sugar content, and total phenolic compounds were observed at 0, 2, 4, 6, 8, and 10 days of storage. The results of the study showed that MAP and heat treatment could maintain freshness and slow down the degradation of fresh-cut cavendish quality. The combination of MAP treatment with 73.70 % argon gas and heat treatment at 40 °C for five minutes can slow down the degradation of fresh-cut cavendish quality and suppress the total titratable acidity formation until the end of the storage period (ten days).

Abstract

Mangosteen (Garcinia mangostana L) is one of the commodities of Indonesian fruit and is used as an export primadona that became the basis of Indonesia to increase the currency of the country. The quality of the fruit can be seen from the surface, whether there is damage or not. The sorting that the farmers have been doing all this time is still using the conventional way, that is, with the sense of sight. This conventional method seems to be less effective because it takes a lot of energy, takes a long time, and there are different perceptions between farmers. To solve this problem, a method of surface quality extraction of mango fruit will be developed based on image processing. The initial stage of image processing is with the image size equation then the image is converted to grayscale mode, then a discrete curvelet transformation is performed. The next stage is the extraction of mean, energy, entropy, standard deviation, variance, sum, correlation, contrast, and homogeneity. The result of the subsequent feature extraction is used to enter a value at the classification stage. From some of these extractions it will be known which extraction has the highest accuracy value. The method of classification used is Linear Discriminant Analysis (LDA) with the method of K-Fold Cross Validation which in this study is divided into 4-fold cross validation. After testing on 120 images, the highest value of accuracy is with extraction of standard characteristics deviation of 91.7% and variance of 88.4%.
