Abstract

Electricity is a basic need of human beings. The consumption of electricity usage is getting bigger and bigger. Electricity usage is usually wasteful due to lack of public awareness and ineffective use of electricity. With this problem, the author aims to design loT-based electric power usage monitoring system in home electrical appliances. This tool is designed using sensors to detect the value of the voltage and current of the load attached to the electricity but still using the BLYNK application as a server and application to monitor the use of electric power through a smartphone application. The measurement results include the data of current, voltage, and electrical power used. This system can also remotely switch appliances ON/OFF. The test was conducted by comparing the results of the power value from the power meter with the power value in BLYNK application. After the test, the results of the comparison between the monitoring tool and the power meter measuring instrument obtained an average power error value of 0.5%. So that the accuracy value of the tool can also be 99.5%. With a large accuracy value, it means that the tool works well and can be used to monitor the use of electrical energy in households.

Abstract

Gas Metal Arc Welding (GMAW) welding technology is a welding method that is widely used in industry. A problem that often occurs is that it is difficult for a welder to control the speed of movement of the welding nozzle, which can affect the quality of the welding results. With welding tools that can control the movement of the welding nozzle, this problem can be overcome and increase the efficiency and productivity of the welding manufacturing process. The method for testing the quality of welding results is analyzed visually using the visual test and penetrant test methods. The use of GMAW welding tools for pipe butt joints using DC motor control to vary the movement of the welding nozzle is effective, making it easier for the welder and good welding results. Good welding results were obtained for setting the welding nozzle movement time in 1.4 seconds and 1 second for one left and right the movement cycle on a pipe joint rotating at a constant speed of 24 rpm. Setting the time for the welding nozzle movement in 0.6 seconds for one cycle of left and right movement produces poor welding in pipe joints that rotate at the same speed.

Abstract

Exploring educational opportunities beyond the official curriculum and campus environment is a means for students to enhance the competencies of future graduates who can thrive in both national and international industrial settings. This study's objective is to assess students' awareness and engagement with the Independent Learning Independent Campus Program (MBKM) policy and its consequences. The research methodology employed in this study involves a survey using descriptive analysis techniques. The study involved 350 undergraduate students as participants, and data collection was conducted through a questionnaire comprising two sections: one for capturing respondent demographics and the other for inquiring about their perspectives on the Independent Learning Independent Campus Program (MBKM) policy. The study's findings suggest that students exhibit a considerable level of awareness regarding the Independent Learning Independent Campus Program (MBKM) policy, and their participation is also notably high. Moreover, the feedback regarding the impact of the MBKM policy on students is positively inclined. This positive response is rooted in the advantages offered by the MBKM program, such as enhanced learning experiences, the allocation of 20 credits, and the development of soft skills. Consequently, the MBKM policy holds the potential to encourage greate.r student involvement in extracurricular learning activities outside the official curriculum and campus. Hence, the outcomes of this study carry several important implications. First, because students are so aware of the MBKM policy, they will continue to attend the program with great enthusiasm. Second, because there is a lot of student interest in the Independent Learning Independent Campus Program (MBKM) program, the quality of learning that takes place off campus will improve. Third, the study program will successfully maintain the Independent Learning Independent Campus Program (MBKM) program. This is based on the advantages of the Independent Learning Independent Campus Program (MBKM) program, which can offer a variety of skills, knowledge of different cultures, and adaptability, including leadership skills.

Abstract

The public sector budget has a function as a local financial management planning tool. BPKPD district of Hulu River South is an institution that carries out the duties of the local government in the planning of the regional budget. This study is aimed at finding out the application of budget functions as a tool for planning income and expenditure in the BPKPD district of Hulu River South. This study uses a method of quantitative research using a descriptive approach. The study uses three types of measurement analysis to find out the use of budget function as a planning tool, namely, the process of budgeting, the level of effectiveness of budget income, and the degree of efficiency as well as deviations in budget expenditures. The income budget effectiveness rate for 2022 reached 118.60% (more than 100%) with the category of highly effective, coming from three types of regional income. First, Regional Real Income with an efficiency ratio of 87.51% belongs to the effective category. Second, Transfer income with an effectiveness rate of 119.82% belonging to the highly efficient category. The calculation of the expenditure efficiency ratio showed less efficient access, with a ratio of 93.06%. Operations purchases obtained a rate of 75.92% in the efficient category. Capital purchases gained access to efficiency ratios of 91.41%, including the less effective category. Unexpected expenditures reached the rate of efficiency of 17.92%, in the highly efficient categories. Lastly, the transfer spending sector has an efficiency rate of 99.81% in the less efficient category. Secondly, the calculation of the variance analysis in the regional spending sector shows that the entire account in the local spending area has more variance. No spending account has a budget deficit as a result of the realization or achievement of greater income than estimated. The deviation that occurs on the entire account of the shopping sector is favorable.

Abstract

Tengkuit is a traditional tool used by farmers to care for katuk, chilies, lumai, and others. The problem that farmers complain about is frequent wear and tear and chipping, which according to farmers and craftsmen must maximize quality and this must increase production costs and farmers' expenses. As time goes by, innovations have been made by humans to increase the durability of an object or material by increasing its hardness to save or reduce production costs. This research used qualitative approach with the taguchi method. The Taguchi method is a new engineering technique that aims to improve product and process quality while minimizing costs and resources. Taguchi's experimental design is more efficient because it allows searches involving many factors and numbers, and has good large-scale violent response. The maximum check value is the optimal parameter value for the tengkuit making process. Temperature and cooling media are very influential factors in testing hardness for making tengkuit. The results of the hardness research were shown as the lowest hardness value at a temperature of 600°C, with well water cooling media with a value of 24.3 HRC, and the highest hardness value at a temperature of 800°C. with bromus oil cooling media at a temperature of 700 ° C and a hardness value of 42.9HRC.

Abstract

Mount Sinabung is an active volcano located in the Karo Highlands, specifically in the Karo Regency of North Sumatra, Indonesia. Sinabung and Mount Sibayak, located in North Sumatra, are both active volcanoes and rank as the second-highest peaks in the province. However, it saw a dramatic resurgence and became active once more with a volcanic eruption on August 27, 2010. The most recent eruption of this mountain took place on February 19, 2018 and is ongoing. The significance of this situation prompted the study team to engage in the development of an empowerment paradigm. The objective of this study is to create a digital tourism framework for communities impacted by the eruption of Mount Sinabung, utilizing virtual reality technology as a means to facilitate societal repair. The research methodology employed is a hybrid approach. The data results are processed and evaluated using a customized technique that takes into account the specific demands of the community and parties involved in the collaborative model development. This analysis is done both qualitatively and quantitatively. The analytical stage of discussing the desired digital tourist model employs the theory of viewing techniques, which is akin to reading, in the form of the selection stage.

Abstract

Campus is the right place to promote the concept of sustainable development to the academic community and the surrounding community. The application of the green campus concept is a sustainable effort to reduce carbon that occurs on the Medan State Polytechnic campus. Based on the UI GreenMetric Guideline 2023, we will find out how much scoring from the existing conditions achieved for the setting and infrastructure (SI) category from the maximum scoring of 15% of the total. By knowing the scoring of the existing conditions, the researcher seeks to be able to increase the scoring of the SI indicator based on the UI GreenMetric Guideline 2023 which will be outlined in the final landscape of Medan State Polytechnic to get the maximum score of the SI indicator based on the UI GreenMetric Guideline 2023. The method used is quantitative using primary data and secondary data. Primary data was obtained by conducting surveys while secondary data was obtained from the Medan State Polytechnic agency. From the results of the scoring calculation for the setting and infrastructure (SI) category, the Politeknik Negeri Medan campus received a score of 440 out of 1500 points or 29.33%. For efforts to increase scoring, the maximum value is 575 points out of 1500 points. Only 9% can be maximized for additional scoring that can be done on the Politeknik Negeri Medan. So that the final score obtained is 38.33%. The researcher hopes that the research can be useful for Politeknik Negeri Medan as a sustainable effort to implement the green campus concept at Politeknik Negeri Medan.

Abstract

To help businesses or organizations manage their inventory of goods more effectively and efficiently, information management is crucial. Businesses can monitor and manage the amount of goods on hand, prevent shortages or excess inventory, and streamline the shipping and receiving process with effective information management. Instead of utilizing a technology-based (computer-based) management system, the equipment management system in the Tool Crib of the POLMED mechanical engineering workshop is still conventional. wherein equipment borrowed by students or other stakeholders is not information management-based and is instead still documented in a form. Therefore, it is impossible to effectively control the quantity, quality, and identity of the tools that are borrowed. And the fact that the equipment is frequently misplaced or lost presents a challenge. The Waterfall method is the approach devised during the research. Software development follows a methodical design called the Waterfall Method. This study used quantitative descriptive research as its methodology. A method or approach to solving research problems in quantitative descriptive research involves characterizing the state of the object under investigation a person, organization, factory, etc. as it is based on real facts at the moment the research was conducted or is being conducted.
