Abstract

Garlic production in Indonesia is quite large. So far, we have known that many garlic are sold raw without being processed. But lately garlic is widely developed processing garlic into other products like black garlic that being produced by Mrs. Vetie Kusumaningsari, S.E. in Yogyakarta. The objective of this study is to analyze the feasibility of Black Garlic's Home Industry. The method being used in this study are break even point (BEP), net present value (NPV), benefit/cost (B/C) ratio, and payback period to analyze the data being collected. The result of this study indicates that BEP can be reached 334 cups product, with 7% of interest NPV indicate positive at Rp 10.713.817,8, B/C ratio was at 0,7 and payback period (PP) at 0,045 year. In conclusion regarding to the study, black garlic's home industry feasible to run and develop.

Abstract

Ginger breadfruit leaves wedang is a functional beverage made from breadfruit leaves that contains high antioxidant value, ginger and palm sugar. Moreover the adding healthy value function in ginger breadfruit leaves wedang product, also to utilizing the breadfruit leaves into functional beverage of ginger breadfruit leaves wedang in order to be accepted by the people. This research aims to know 4%, 5% and 6% breadfruit leaves addition influence to antioxidant content (gallic acid, quercetin and kaempferol) and organoleptic properties. This experiment research using Completely Random Design (CRD) with three kinds of treatment. The analyzed data using One Way ANOVA, if the treatments shows difference significant, then the analyzed data should be proceed by Duncan’s Multiple Range Test with 5% confidence interval. The highest value of gallic acid antioxidant contect leads in 6% ginger breadfruit leaves wedang about 92,326 μg/ml. The highest value of quercetin antioxidant contect leads in 6% ginger breadfruit leaves wedang about 36,767 μg/ml. The highest value of kaempferol antioxidant contect leads in 6% ginger breadfruit leaves wedang about 25,921 μg/ml. The highest score of color hedonic is 3,97, and the highest score of taste hedonic is 3,67. The highest score of color hedonic quality is 3,11 with dark brown color criteria. The highest score of taste hedonic quality is 4,17 with a bit bittersweet taste criteria

Abstract

Quality control is needed to produce quality products. Quality control is aimed at reducing defects in production results. In this study, we focus on the analysis of the types of defects, the number of defects, and the causes of defects in dry noodles, including the attributes of moisture content, shape, and packaging. The population in data collection was all dry noodle. The sampling method for the moisture content attribute was purposive sampling. Data collection methods by observation, interview, and literature study. Data were analyzed using pareto chart, control chart (p-chart), and fishbone diagram. The control chart showed four points of defective products that were beyond the control limits and six points that were within the control limits. Finally, the fishbone diagram demonstrated that two dominant factors causing defects in dry noodle products were machine and the processing method.

Abstract

Acetobacter xylinum greatly contributes to the fermentation process of nata de coco. It converts glucose in coconut water into cellulose slabs. The slabs turn into clear white and solid in form, called nata. This analysis is aimed to identify types and causes of damage to nata de coco in the fermentation process. Observation of the criteria of raw materials, cooking process, the making of an Acetobacter xylinum starter, pouring the medium into the stray, and the harvesting process of nata slabs was carried out in the fermentation process. Data collected were analyzed, and research problems were solved using the Fishbone diagram. Several methods applied in data collection were observation, interview, hands-on practice, documentation, and literature study. The results demonstrated some types of damage to nata slabs in the fermentation process, e.g., fungal contamination and defective, watery, and fibrous nata.

Abstract

Quality control is essential in the production line to ensure the quality of the final product. The quality control team ensure the standard of the produced products. This research aims to explore the quality control process in the production of sweet bread in PT XYZ and to determine the major defect of the product. Data were collected through interviews and a literature study. Pareto chart, control chart, and Fishbone diagram were used to analyze the data. These methods identify the kind of defects in the product and understand the process of controlling product quality. The results show that the quality control process had been carried out. However, some product defects were found, such as burned bread (15%), leakage (15%), and sticking (13%). Defect products might be due to some kind of factors such as human error, method production, and the equipment and materials used.
