Abstract: The limitations of conventional distillation technology hinder micro, small, and medium enterprises (MSMEs) from producing herbal products with consistent quality. This study aims to develop an Arduino-based distillation… system equipped with automatic temperature control to improve the production capacity and quality of herbal liquid smoke at CV Moga Permata Perkasa. The research methods include system design and fabrication, functional testing, operator training, and performance evaluation. The results demonstrate a 35% increase in production capacity and stable temperature control within a ±2°C range during the distillation process. These findings indicate that the developed system effectively enhances production efficiency and product consistency. Furthermore, the proposed technology is affordable, easy to operate, and has strong potential for implementation and replication among similar MSMEs.

William Laia, Nani Sri Rezeki
Abstract: This study discusses a peanut shelling machine driven by a gasoline-engineered motor . In Indonesia, many processed peanut products require peanuts as a component, such as salted peanuts, peanut oil, peanut paste, peanut… tofu, and others. Manual peanut shelling is usually inefficient and time-consuming. Therefore, with this machine, which can automatically peel peanuts, it will greatly help save time and increase production capacity. Based on planning calculations for the planned components, the following data was obtained: Gasoline engine used = 5.5 Hp , Pad = 6005 , Belt length to peeler = 65 inches , Belt length to blower = 25 inches , Diameter pulley blower = 4 inches , Pulley diameter peeler = 11 inches , Diameter pulley driver = 2 inches . After analyzing the production/manufacturing costs of this machine, the price for manufacturing 1 peanut peeling machine was Rp4,019,372.24 .

DESIGN AND CONSTRUCTION OF A CORN SHELLING MACHINE WITH A CAPACITY OF 80KG/HOUR USING A COMBO ENGINE

Samuel Haris Purba, Saut Pardede
Abstract: This study discusses the design and construction of a corn sheller with a capacity of 80 kg/hour using an internal combustion engine . A corn sheller is a machine that functions to shell corn to separate the corn kernels… from the corn cobs. In Indonesia, corn is available in abundance in rural areas, especially during the harvest season. In the production process, generally, during the shelling process, many farmers still use the shelling method by hand or using simple tools, which takes quite a long time. The reason people still use the shelling method by hand or using tools is because the price of the machine is too expensive and they are not even aware of the existence of a corn shelling machine. This corn shelling machine with a 5.5 HP internal combustion engine is a tool designed to speed up and simplify the corn shelling process efficiently and produce a fairly large production capacity of 80 kg / hour. To extend the service life of this corn shelling machine, maintenance and cleanliness should be carried out so that the machine can operate optimally without problems. Safety also needs to be considered to avoid unexpected work accidents.

Abstract: This study aims to determine the RELATIONSHIP BETWEEN SPIRITUAL INTELLEGENCE AND LEARNING INTEREST OF GRADE VIII STUDENTS OF SMP NEGERI 2 MERANTI 2022/2023 ACADEMIC YEAR. This type of research is descriptive correlational&#8230; l research. The population in this study were all grade VII students of SMP NEGERI 2 MERANTI as many as 30 people, because the population was small, which was only 30 people, the entire population became the research sample, namely 30 people with a sampling technique. The data collection instrument for variable X was a questionnaire totaling 15 with 4 options which were first tested to determine its validity and reliability. While the variable Y instrument was the documentation of the student grade list (DKN) at the school. The results of the analysis requirements for the normality test of Spiritual Intelligence data were normally distributed with the calculation results obtained (22.33 <43.77) and student learning interest was normally distributed with the calculation results (18.85 <43.77). The results of the linearity test of the data on the Relationship between Spiritual Intelligence and Students' Interest in Learning are linear with the equation Y = 22.77 + 1.22x being linear. The results of the correlation test obtained were 0.453 consulted with r with a significance level of 5% with the number of respondents being 30 people obtained because (0.453 > 0.361) this indicates that there is a Relationship between Spiritual Intelligence and Students' Interest in Learning in Class VIII of SMP NEGERI 2 MERANTI Academic Year 2022/2023. Furthermore, to test the significance of the correlation, it was carried out using the statistical test formula (test "t") obtained at 3.41. This price is then consulted at a significance level of 95% ( µ= 0.05) with dk = n-2 (30 – 2 = 28) obtained at 1.69, because (3.41> 1.69) this shows a Relationship Between Spiritual Intelligence and Learning Interest of Class VIII Students of SMP NEGERI 2 MERANTI Academic Year 2022/2023. Thus, the research hypothesis is accepted as true.
