Abstract

SMAN3 Batam, as one of the well-known high schools in the city of Batam, has difficulty applying physics learning practices, specifically the use of measuring instruments. Where learning is still in theoretical form. Training on the use of The multimeter aims to improve understanding of the basic principles of the use of multimeters in physics practice, including how to measure voltage, current, and resistance correctly in the use of multimeters as electrical measuring instruments in everyday life, as well as strengthen the learning of electrical physics. The research method uses survey and observation methods carried out on students of class XII IPA SMAN3 Batam by providing training on the use of multi tester measuring instruments. To see the progress of practice by giving pretest and posttest questions from the training results The trainees can understand the basic principles of using a multimeter, including how to measure voltage, current, and resistance correctly. In the use of a multimeter, including the right technique for connecting the device to the power source and the object to be measured, and show the seriousness of the students following the training by showing a significant change in the pre-test and post-test scores. Training like this should be done on an ongoing basis.

Abstract

Increasing the usability of computers can not only be used to process data but can also be applied in controlling various tools, one of which is detecting the feasibility of drinking water using the AT89S51 microcontroller. In this case the microcontroller is used to control the PH meter and LCD sensors. After going through several tests, a tool performance has been obtained with the expected characteristics, including the accuracy of sensor readings, the accuracy of LCD control, and the automation of relationships between systems. Furthermore, through the simulation form that has been achieved, it is hoped that this tool can be applied to a more real system with various adjustments and performance improvements.

Abstract

This study aims to analyze and design a web-based teacher attendance monitoring application at SMK Ibnu Sina Batam. We expect this application to enhance the efficiency and effectiveness of teacher attendance management through the use of digital technology. The research methods used include literature studies, interviews, and direct observation of the teacher attendance management process. We design the system using the Unified Modeling Language (UML), implement it using the CodeIgniter framework, and use MySQL as its database. We conduct testing using the Black Box method to verify that all functions operate as anticipated. The results show that this application can monitor teacher attendance in real-time and improve discipline. By cutting down on manual checks and enhancing transparency and accountability in school management, the implementation of this application significantly enhances the quality of education at SMK Ibnu Sina Batam.

Abstract

The research object is the ice cream production process at PT Sejuk Abadi Nusantara, using production and quality-control records from January to June 2024. From 29,530 produced units, 630 defective units were identified, representing a defect rate of 2.13%. Pareto analysis indicated four vital few defects contributing 79.21% of total defects: non-uniform texture, excessive moisture content, uneven color, and non-standard portion size. A 5M1E Fishbone Diagram and 5-Why verification showed that dominant root causes were associated with machine, method, measurement, and human factors, especially freezer-temperature sensor drift, worn freezer gaskets, inconsistent hardening time, weak mixing standard operating procedures, and insufficient operator training. A corrective and preventive action plan was proposed, covering sensor calibration, freezer maintenance, hardening standardization, visual work instructions, operator training, moisture testing, environmental monitoring, and monthly calibration. The proposed actions are projected to reduce total defects from 630 to 222 units per semester, or 64.8%. The study demonstrates how integrated Pareto-Fishbone analysis can transform quality-control records into operational process-improvement decisions for frozen-food manufacturing.
