Abstract

Carrot is a plant that stores carbohydrates in large quantities, post-harvest processing of carrot in Indonesia still limited to get processed into the main ingredients of dishes. This study used two factor, ratio of carrot and water, and lenght of grinding time. The stage of measuring cooling characteristic start with the preparation of raw carrot, washing, peeling, cutting, grinding, and the cooling process (6°C). Cooling characteristic measured are the changing in temperature of puree during cooling process and cooling rate. This study used  the ratio of carrot and water 1:1 (100 gr:100 ml), 1:2 (100 gr:200 ml), 2:1 (200 gr:100 ml), and the lenght of grinding were 1, 2, and 3. The data was taken from 9 samples of treatment combinations. Changed values of combination temperature ranged from 26.98°C to 16.76°C, 27.44°C to 16.79°C, 28.79°C to 17.29°C, 25.81°C to 15.52°C, 28.04°C to 19.03°C, 29.99 to 19.19°C, 26.56°C to 16.96°C, 27.81°C to 19.10, and 27.72 °C to 19.53 °C. Highest average cooling rate occured in the first 5 minutes when the material temperature was still higher than the cooling medium, the cooling rate values in a row were: 0.21; 0.20; 0.30; 0.22; 0.20; 0.20; 0.14; 0.16; and 0.15.

Abstract

One alternative energy source for making organic waste which can be renewed is pineapple waste and tofu waste. Biogas produced from these two materials is environmentally friendly so it does not disturb the environment. The purpose of this research was to determine the changes in temperature and pH that occurred during the formation of pressure and volume of biogas. The method used in this study was an experimental method using a completely randomized design (CRD). There are 4 treatments in this study, namely T1: pineapple waste; T2 : tofu liquid waste; T3 : addition of tofu solid waste; and T4 : addition of tofu liquid waste and tofu solid waste. The measurement results were then analyzed using analysis of variance (ANOVA). If significantly different results were found, a further test was carried out with BNJ. The results showed that the addition of tofu waste significantly affected the temperature, pH, pressure and volume of bioga. The average temperature for each treatment was 28oC, while the highest pH was 8.55. The highest pressure calculation results were found at T4 of 109.42 N/m2, while for the highest volume it was found at T4 of 0.000016642m3. Based on the description above, it can be concluded that the addition of tofu waste has a significant effect on the formation of biogas

Abstract

The drying process carried out in making banana sale will cause the moisture content in banana sale with various types of banana packaging is very influential, the storage of banana sale has decreased quality in terms of temperature, humidity and moisture content. The purpose of this study was to determine the effect of packaging method using (opp plastic, vacuum and jar) and storage duration on temperature, humidity and moisture content of banana sale. This study consisted of one factor, namely packaging using opp plastic, packaging using vacuum and packaging using jars. Duration of storage with 15 observations for 1 month every 2 days 1 observation (2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, and 30) in a refrigerator temperature around 7˚C. Therefore, a method is needed to maintain the quality of banana sale during storage by applying packaging technology. Data were processed using a completely randomised design (CRD). Factorial with three repetitions, the parameters analysed were the effect of temperature, humidity and moisture content. The results showed that the storage of banana sale with various types of packaging for 1 month gave the best results on the use of packaging using vacuum type for the best storage for 1 month compared to the use of packaging types using opp plastic and jars.

Abstract

Banana one of the commodities that are widely cultivated by the people of Indonesia. Banana sale is a food processed by ripe bananas which are thinly combed and then preserved by drying. During the drying of the sale of bananas, the water content decreased in terms of temperature and humidity, so a method is needed that canmaintain the water content of banana sale during drying by applying drying technology using an electric oven. The purpose of this study was to determine the effect of oven drying on the temperature, humidity, moisture content of sale bananas with kepok banana as the basic ingredient. This study used a completely randomized design (CRD), the factor used was temperature treatment. Factorial is repeated three times, parameters analyzed were temperature, humidity and moisture content of banana sale drying. The results showed that drying banana sale with a temperature of 60˚C for 12hours gave the best water content compared to temperatures of 40˚C and 50˚C so that it met the SNI quality for a maximum of 15-20% water content of banana sale.

Abstract

Groundnut production in West Nusa Tenggara Province has increased every year. Post-harvest handling of peanuts at the farm level is generally still done traditionally, especially when harvesting, threshing pods or stripping the peel, which requires a lot of labour. This study aims to determine the effect of peanut pod diameter on each parameter, tool efficiency, and tool production quality. The method used in this research is the experimental method by conducting experiments directly in the laboratory. The parameters observed in this study are the efficiency of the tool, the need for electrical power, and the quality of peanut seed stripping. The analysis results showed that each treatment with different diameters had no significant effect on each parameter observed. The stripping quality of the three treatments has not met the standard.
