Abstract

Technological developments in the food sector make the appearance and packaging of food products more varied with the aim of attracting consumers to buy these products. Currently, canned food and beverage packaging dominates the market, not only in modern markets, but also in traditional markets. One of the packaged beverage products that is popular with the public is fruit juice packaging. This study aims to determine whether packaged fruit drinks circulating in the community comply with SNI 01-2981-1992 based on organoleptic parameters, pH value, sugar content, and vitamin C levels. Samples of packaged fruit drinks were randomly selected as many as 5 types of samples. This research uses qualitative and quantitative analysis approaches. From the results of the study, it can be concluded that the sample fruit juice packaging is suitable for consumption and meets the provisions of SNI 01-2981-1992.Keywords : fruit juice packaging, organoleptic, pH value, sugar content, vitamin C

Abstract

This study aims to analyze the effect of implementing Olabs virtual lab-based physics learning on learning outcomes, compare student learning outcomes using Olabs virtual labs with conventional methods, and identify the advantages and limitations of implementing Olabs virtual labs in physics learning. This study employed a quasi-experimental approach with a pretest-posttest control group design to evaluate the effect of Olabs virtual lab implementation on student learning outcomes in physics courses. Therefore, the instrument used in this study was a pretest-posttest. The study population was Physics Education student at HKBP Nommensen University. After administering different treatments to the two classes, the control and experimental classes, the average learning outcomes for the control class were 66.56 for the pretest and 75 for the posttest. Meanwhile, in the experimental class, the average pretest acore was 66.92 and the posttest acore was 85.38. the data analysis concluded that implementing Olabs virtual lab-based physiscs learning improved the learning outvomes of physics education students in the experimental class.
