Abstract

Semboro Siamese oranges have a higher selling value However, the selling value of the Siamese oranges is still relatively low, thus some efforts need to be made to increase the added value of the Siamese oranges. One way that can be done is by producing Siamese orange extract using the High Pulsed Electric Field (HPEF) technology. The aim of this research is to determine the added value and business development strategies of the HPEF Siamese orange extract. The analysis methods used were Hayami and SWOT. The research results show that there is a linearity between the two methods which indicates a positive value with a ratio of value and added value that is classified as high category, and there are development strategies that can be implemented by expanding marketing areas and improving product quality and safety by applying the existing technology.

Abstract

Cucumis melo L. is an annual plant and has high economic value so it is widely cultivated in Indonesia. Possible efforts include providing amino acids and hydroponic methods. Determining the provision of amino acids with the best concentration for the growth and quality of hydroponic plant production is the aim of this research. The research method was a completely randomized design (CRD) consisting of factors with four levels of amino acid concentration, namely G0 (without administration of amino acids), G1 (2 mgL-1), G2 (4 mgL-1) and G3 (6 mgL-1) Meanwhile the data was analyzed using the F test. The results for all parameters, both growth and production of melon plants, were not significantly different. Although the concentration of amino acids given to melon plants did not show any influence on the quality of hydroponic melon production, there was a good increase in diameter of 13.60 cm and fruit weight of 1.46 kg. Based on the administration of amino acids, it can be concluded that although it did not have a significant effect, the fruit diameter in the 6 mgL-1 treatment was the largest.

Abstract

Mozzarella cheese is a type of fresh cheese which is characterized by being elastic, fibrous and soft. This research was carried out using the RSM-CCD (Response Surface Methodology Central Composite Design) method which aims to determine the optimum conditions for coagulation time and pineapple juice concentration in making mozzarella cheese with a combination of 13 treatments obtained from the expert-13 design software. The research method uses two factors, namely coagulation time with a coagulation time limit of 25-35 minutes and pineapple juice concentration with a limit of 2.5-3.5%. The responses used are curd weight , water content, and elongation using a quadratic model. The research results showed that the optimal treatment combination was a coagulation time of 25 minutes with a pineapple juice concentration of 2.5%, the resulting desirability value was 57.4%. From the solution results, an estimate of the maximum response was obtained with an average value of curd weight of 248 grams, water content of 41.55%, and elongation of 17.95 inches. The confirmation results obtained an average of curd weight data of 244.5 grams, water content of 38.97%, and elongation of 17 inches. The average confirmation test data for each response showed that the results were in accordance with the predicted value with a confidence interval ratio of 95%.

Abstract

Xylose is a sugar obtained from breaking down hemicellulose. It is a polysaccharide found in the cellulose fibers of plant cell walls. One example of a plant containing hemicellulose is coffee, especially its waste called Coffee Cherry Processing Waste (CCPW). Its process's 10 L capacity production design was carried out to establish its mini factory. The financial feasibility study of each processing unit was designed. The research method used was quantitative methods. Apart from that, the approach used in this research is descriptive. The test results show that the crystalline xylose sugar processing unit is feasible to develop because the calculation results of the financial feasibility criteria are met with NPV > 0, B/C > 1, IRR 51%, PBP for two months < 5 years, which means the business owner could have returned his capital before the project period ends and BEP Q of IDR 15,565,013.54 while BEP Rp IDR 22,002479.88 was declared feasible because the BEP value was lower than the net income from xylose crystal sugar.

Abstract

Marungga leaves have the potential to be a source of antioxidants, minerals, and carbohydrates. These leaves can be processed into flour for further processing into various products. Marungga leaves must be dried before they can be processed into flour. They are heat-sensitive, so some of their nutritional content will be degraded if dried at high temperatures. A dehumidification system dryer was designed and built to produce low temperature and humidity to overcome the problem of high-temperature drying. The purpose of this study was to evaluate the performance of the dehumidification dryer and to assess the quality of dried Marungga flour. Drying was carried out under normal working conditions for 8 hours, with air temperature and humidity monitored at 20-minute intervals. The dried Marungga leaves were milled into flour and analyzed for physicochemical properties. The test results yielded the following data: air flow rate 0.109 kg/s, drying temperature 33.5°C, relative humidity 54.7%, drying rate 0.732 kg H2O/hour, specific humidity drop 0.01703 kg H2O/kgda, Carnot COP 6.8, actual COP 4.2, efficiency 61.8 %, SMER 0.055 kg/kWh. The Marungga flour produced had a moisture content 6.4%, protein 36.86%, antioxidants 58.765%, vitamin C 50.338%, and green color (a = -12.75) meets SNI 9228: 2023
