Abstract

This research purpose to create a tool that can facilitate seaweed farmers in the process of harvesting other seaweed products. The working principle of the seaweed harvesting tool is to tie the seaweed rope bent to the roll on the harvester followed by rotating the roll connected to the pedal, when the roller is rotated, the stretch rope will pass through the separator between the rope and the seaweed, so that the seaweed is separated from the stretch rope. , by applying this working principle, it can make it easier for farmers who previously used the principle of working manually by pulling the rope without the help of any tools, after that the farmers also had to separate the seaweed that had been collected manually without the help of any tools so that it required more energy and time. long. This seaweed harvesting tool that was created can simplify and shorten the time for farmers in the harvesting process, as evidenced by the results of field research at the time of testing the tool, the results obtained are by conventional methods the average time used by farmers is 7 minutes 58 seconds while the results testing using a seaweed harvester using a roll diameter of 100 mm which is 5 minutes 28 seconds and by using a roll diameter of 50 mm which is 6 minutes 35 seconds. In terms of time efficiency of the seaweed harvester, a roll with a diameter of 100 mm is an efficient roll with an average time of 5 minutes 28 seconds.

Abstract

This study is designed to develop and analyze the level of validation, student learning outcomes, and student responses to the use of video learning media. This research refers to research and development (R&D) using the ADDIE development model. The object of research is a learning video media product that was tested to 20 students in small groups, 2 media experts and 2 teaching material experts who evaluated and provided input related to learning video media and instruction books related to video material or content. The study response consisted of 30 grade X ATPH 3 students in a large group. The results showed that the results of media expert validation were in the "Very Valid" category with an average score of 3.8, while the results of material expert validation were in the "Valid" category with an average score of 2.67. From a small group of 20 students, 30% achieved results in the "Very Valid" category, 65% "Valid" and 5% "Less Valid". The average response result of the 30 large group students was 87.42 which was included in the "Very Good" category. Students in the experimental group who carried out the learning process with supporting media in the form of learning video media obtained a higher total average score compared to students in the control group who underwent the learning process without supporting media.

Abstract

Sweet potato flour can also be used as a substitute ingredient in food manufacturing. Good control of the drying process is important to produce quality sweet potato flour. To understand the impact of drying on purple sweet potato, an in-depth understanding of drying kinetics is required. The equipment used in this research are cabinet dryer, analytical balance, electric oven, spatula, gegep, porcelain cup, desiccator, and aluminum cup. The material used in this study was fresh purple sweet potato obtained from Pasar Terong, Jl. Terong, Wajo Baru, Kec. Bontoala, Makassar City. Drying temperature became the treatment variable in this study. The temperature used consisted of 3 variations, namely 50oC, 55oC, and 60oC. Drying was carried out for 8 hours and measuring the moisture content every 1 hour during drying. The material moisture content (M) to be determined is the initial moisture content, final moisture content and material moisture content during the drying process. The moisture content of the material is determined using the oven method. Seven different drying mathematical models were evaluated. Determination of effective moisture diffusivity was carried out according to the Second Fick's Law Equation assuming the geometric shape of the material is slab. The drying rate showed a decreasing pattern along with the drying time of the material at various temperature variations. Based on the test results of the three statistical parameters, the Weibull Model has the highest correlation coefficient value.
