Abstract

PT Marina is a company engaged in bottled mineral water production, where one of its products is glass packaging. The fluctuating demand for glass bottled drinking water products causes companies to plan optimal production. Based on the results of image scanning using the SCAPSA application, it was found that the total return was 2193 glasses in December 2024. Based on the identification results using the Pareto diagram method, it was found that the highest product return from consumers was needle leaks, namely 895 glasses. The identification results indicate priority improvements that will be carried out using the Fuzzy AHP method with triangular fuzzy numbers. At the actor level, the highest normalization result was obtained for the production section with a defuzzification value of 0.78. At the factor level, the highest normalization was obtained for the quality of the glass packaging with a defuzzification value of 0.49. Hence, the optimal tension temperature setting on the felling machine was an alternative improvement for returning leaking needles with a defuzzification value of 0.55 and a consistency index of 0.03. Based on the results of the improvements, it was found that the company could reduce returns on products by 85.70% to 128 glasses.

Abstract

The condition of culinary tourism in Bogor is dominated by modern cuisine, which has led to the exclusion of traditional cuisine. This research aims to determine the factors influencing tourist or consumer satisfaction in choosing traditional culinary delights in Bogor City. The method used in this study is quantitative. The analysis used in this research to determine the level of feasibility of the questionnaire used was the validity and reliability test to test the questionnaire for determining the attributes of tourist or consumer satisfaction. The subsequent analysis used in this research is a regression analysis to determine the factors influencing consumer satisfaction in choosing traditional culinary delights in Bogor City. The research results show that culinary products can make tourists or consumers satisfied. Bogor City's traditional culinary products consist of a variety of products with varying levels of taste, quality, presentation, and packaging. The price, service, or motivation don't affect tourist satisfaction when choosing culinary.

Abstract

Accumulation of egg stock in warehouses is currently the biggest problem of product loss due to damage to egg agents. This problem occurs partly because egg agents in Bogor cannot predict final inventory availability, so the number of egg orders exceeds storage capacity and is damaged due to being stored in the warehouse for too long. A prediction model for the final stock availability of eggs (crates) was developed. The prediction model for the final stock availability was based on the number of egg agents ordering from suppliers and the selling price of eggs using the Adaptive Neuro Fuzzy Inference System (ANFIS). The ANFIS model uses three variables: orders to suppliers, selling prices, and inventory, with 50 training data points and 30 testing data points, namely, orders to suppliers, selling prices, and inventory. Based on the results of training and testing data, it was found that the range of the Sugeno fuzzy model for the supplier order variable was 150 - 350 cases, and the selling price was IDR 24,000/kg - 29,500/kg with a fuzzy triangular membership set. The simulation results show testing and training data with epoch = 100 using fuzzy Sugeno, and the error value = 13.7. The results of the training model's determination test (R2) obtained a value of R² = 81.02%, and the testing model had a value of R² = 81.23%. The determination value (R²) above 80% indicate that the model is suitable for predicting the final stock amount for egg agents.

Abstract

The high consumption of low-fiber sweet bread based on wheat flour in Indonesia and the dependence on wheat imports encourages innovation in bakery products using local fiber sources. This study aims to develop choco banana bread as a fiber-based food by substituting wheat flour with a composite of rice bran and beneng taro flour, evaluating its sensory quality and nutritional content. Experimental research using a Completely Randomized Design with three formulas, each containing 70% wheat flour and 30% composite flour with a ratio of rice bran: beneng taro F1 (65%:35%), F2 (50%:50%), and F3 (35%:65%). Sensory evaluation by 35 semi-trained panelists using hedonic tests (appearance, color, aroma, texture, taste, overall acceptance) and hedonic quality (color, taste, aroma, texture, mouthfeel) showed that F3 was the best formula based on the Exponential Comparison Method; The hedonic test showed significant differences (p<0.05) in appearance, color, aroma, and overall acceptability with F3 obtaining the highest score, while texture, taste, and other hedonic quality test parameters did not differ significantly (p≥0.05). F3 (60 g/serving) contains 204 kcal, 5.1 g protein, 7.9 g fat, 28.3 g carbohydrate, and 8.8 g dietary fiber, thus fulfilling the claim as a fiber-rich food, containing 1.5 times more protein, and 7 times more dietary fiber than commercial products. These findings indicate that rice bran and taro have the potential to produce fiber-rich bread with sensory qualities acceptable to consumers, supporting food diversification, and reducing dependence on wheat imports.

Abstract

Nutrition is one of the most common health problems in Indonesia. Being under or overnourished will affect their development. Children who are malnourished will experience reduced physical, cognitive and mental growth. In order to improve knowledge, attitudes and practices of healthy food selection, school-age children need nutrition education. Providing nutrition education can be done using various media such as visual media. This research is a quasy experimental research with pre-post intervention study. The population was students at SDN Kedunghalang 2 Bogor. The samples in the intervention and control groups were 5th grade students at SDN Kedunghalang 2 Bogor who were selected using purposive sampling technique. The data were analysed by inferential statistics using paired sample t-test, Wilcoxon test, independent sample t-test, and Mann-Whitney test. This study included 47 grade 5 students at SDN Kedunghalang 2 Bogor. Total female subjects were 26 and male subjects were 21. A total of 18 people stated that nutriplay media is very interesting as a nutrition education media. There was a significant increase in knowledge in the intervention and control groups. However, there were no significant differences in attitudes and practices between the two groups. Nutriplay is a nutrition education media that can be well received by elementary school students and can increase subject knowledge. The attitudes and practices of the subjects did not improve significantly because it takes a long time and there is a need for the involvement of teachers and families in nutrition education programmes, so it is better not only the role of students to be involved in providing nutrition education.
