Abstract

The purpose of this study is to obtain the right temperature and time for the manufacture of dragon fruit peel powder and to obtain the optimal total yield and water content. The method used in the spraying process is Foam Mat Drying. The method used for optimization is the Response Surface Method (RSM) with a factorial centralized composite design 22. The factors used are the temperature of 60°C, 70°C, and 80°C and the time is 5 hours, 6 hours, 7 hours. The results showed that the composition of the formula was the best at a temperature of 79,214°C and a time of 5,007 hours. It can be predicted that the optimal formula gets a yield value of 16.109%, and a moisture content of 4.662%. The total powder obtained in 1 day of production is 5000 grams, if the production for 1 week is 35,000 grams, then 150,000 grams will be obtained for 1 month of production. It was concluded that the optimal formula that has been obtained can be used as a model for making powder from dragon fruit peel.

Abstract

Bondowoso is the best tape-producing region in East Java, with a production of 435,969 kg in 2018 . One of the tape production centers in Bondowoso is UD. Raja Tape. This study aims to identify the quality attributes of Raja Tape products and determine the operational policies needed to improve product quality at UD. Raja Tape. The Quality Function Deployment (QFD) method is used to identify and understand customer needs and desires into relevant technical specifications for the production process. This research was conducted over three months, using primary data obtained through field observations and interviews, as well as secondary data from related literature. The research stages include identifying products and competitors, conducting product surveys to gather the voice of the customer, identifying technical parameters, analyzing the relationship between customer importance and technical parameters, and constructing the House of Quality (HoQ). The results indicate that the application of QFD can identify key areas that need improvement in the tape production process, such as raw materials, fermentation techniques, and packaging. Implementing the recommendations from the QFD results led to significant improvements in tape product quality, marked by increased customer satisfaction and reduced complaints. This study demonstrates that the QFD method can be an effective strategy for improving product quality in the traditional food industry.

Abstract

Jember Regency is one of the oyster mushroom producing districts in Java Province East. The relatively low price of raw oyster mushrooms means that it is not enough to support the economy of oyster mushroom farmers. Efforts to get added value from oyster mushrooms are by processing oyster mushrooms into processed products. The research aims to determine the level of financial feasibility of businesses and the added value of the oyster mushroom agro-industry in Jember Regency. The research was carried out using survey methods and in-depth interviews with oyster mushroom and industry experts as well as secondary data from literature, articles, journals and data from the Central Statistics Agency. Calculating added value using the Hayami method and calculating financial feasibility analysis of products that have high added value. The results of the added value analysis using the Hayami method show that the oyster mushroom product that has the highest added value is oyster mushroom broth amounting to IDR 172,688- (profit percentage 69.08%), oyster mushroom kebab IDR 47,751 (profit percentage 59.69%) and followed by crispy oyster mushrooms amounting to IDR 40,158 (profit percentage 57.37%) followed by oyster mushroom nuggets amounting to IDR 37,048 (profit percentage 55.57%). The financial feasibility results show that the oyster mushroom agro-industry in oyster mushroom broth products is feasible to run. These eligibility criteria show that at an interest rate of 9.75% the NPV value is IDR 626,388,706, the IRR value is 43.25%, the Net B/C Ratio is 1.12 production break-even point is 22,716 units per year, return on capital is 3.86 years. Sensitivity analysis of financial feasibility with an increase in raw material prices of 10%, 20% and 30% still shows a feasible decision. In the sensitivity analysis, a decrease in the product's selling price of 5% and 10% indicates that the decision is feasible, while a decrease in the product's selling price of 15% indicates that the decision is not feasible to carry out.
