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

Roses from Karangpring Village are a mainstay of Jember Regency and are widely used as sowing flowers. In addition to sowing flowers, roses can also be processed into various processed products such as tea bags, rose jam, candy agar. In making rose tea, the drying process greatly affects the quality and chemical content of the tea. This study aims to determine the effect of temperature variation and drying time on chemical characteristics, organoleptic test, and shelf life of rose flower tea. The materials used were rose flowers, DPPH solution, ethanol, distilled water, amylum solution, ascorbic acid, gallic acid, Na2CO3 7.5%, Follin-Ciocalteu, KCL, HCL, acetic acid, sodium acetate, AlCl3, quercetin. The main tools used in this study are measuring flask, centrifuge, micro pipette, erlenmeyer, UV-VIS spectrophotometer, oven, cup, balance, vortex tube, test tube. Based on SNI dry tea in packaging 3836: 2013 polyphenol content in tea products has a minimum value of 5.2% and a maximum value of water content of 8.0%, thus the polyphenol content and water content of rose flower tea are included in the category set by SNI dry tea in packaging. The highest water content value was found in the P3 treatment of 0.940%, antioxidant content value of 39.181%, polyphenol content of 32.312 mg GAE/g, anthocyanin content value of 4.713%, vitamin C content value of 29.371%, flavonoid content value of 42.521 mg QE/g. The results of the organoleptic test showed that panelists gave scores to treatment P2 with a drying temperature and time of 60oC for 5 hours, and had a shelf life of 17 days.

Abstract

Jember Regency has laying chicken egg in 2021 amounting to 12,223,473/kg, Balung District became the highest egg producing area reaching 2,235,266/kg. In the following year, productivity increased, and the production of laying chicken eggs in 2022 amounted to 12,251,219/kg. Balung District still become the district with the highest egg production in Jember which amounted to 2,240,340/kg. Yayun Farm is one of the small-scale laying breed chicken farming businesses in Balung District which has been running for a long time and has a high commercial value, namely the large consumer demand for eggs. However, Yayun Farm still experienced several problems in developing its business. So the purpose of this study is to find out internal and external factors, alternative strategies, and strategic priorities in developing the Yayun Farm business. The results of the research in the SWOT analysis stated that the position of Yayun Farm is located in quadrant I, where the chosen strategy is the Strength/Opportunities (SO). With limited resources to implement alternative strategies simultaneously, AHP analysis is carried out to find strategic priorities from alternative strategies obtained from SWOT. The priority of the strategy selected with the highest weight is to improve and maintain product quality and quantity (0.667371852). The implementation of this strategy aims to maximize the potential possessed by Yayun Farm, even though there are limited development funds, farm operations can still develop and become better.

Abstract

Crackers available in the market only provide a small portion of daily protein needs. Tuna (Euthynnus affinis) belongs to the Scombridae class and is an important commodity in Indonesia. The high nutritional value of tuna fish includes a considerable amount of protein, ranging from 22.6-26.2 g/100 grams of meat. Of the various ingredients that can be added to increase the protein content of crackers, one option is to use tuna flour due to its high protein content. This study aims to identify the optimal ratio and drying period for certain chemical properties as well as considering color, aroma and taste preferences by panelists as well as the shelf life of popular tuna crackers. The parameters used in this study include moisture content, ash content, fat content, protein content which measures the nutritional value; pH which indicates the level of acidity; swelling strength as an indication of textural quality along with organoleptic tests (taste, color, aroma and overall preference) which enables sensory evaluation analysis. The results showed that crackers with the addition of tuna flour have met the quality requirements of SNI 2973-2018. The tuna flour crackers formulation has a moisture content of 0.4%, ash content of 0.2%, protein content of 7.11%, fat content of 16%, pH of 6.48-6.50 and expandability of 0.6%.
