Abstract

Numeracy and literacy are the focus of Indonesia's education system. This is evident from the implementation of the Minimum Competency Assessment (AKM), which has been part of the national annual assessment since 2021. The results are analyzed and reflected upon to assess the quality of education in implementing schools. Students' numeracy skills can improve if they use reasoning to solve problems. Reasoning connects the concepts they hold with the context of the problem at hand. Reasoning results are used to interpret, analyze, and make decisions. The reasoning in question focuses on adaptive reasoning (reflection, explanation, and justification). Research was conducted to describe the adaptive reasoning of high school students through the answers of students who participated in a reasoning competition. The instrument used is a numeracy test. This research is qualitative with descriptive methods. Analysis was conducted on the three student answers that obtained the highest scores (purposive sampling) and focused on the fertilizer theme. This theme is presented in graphic form as a stimulus with two questions that students need to answer. The data analysis technique in this research involved reducing the data. The result obtained was that one student used aspects of adaptive reasoning (reflection, explanation, and justification) completely in answering questions. This indicates that this student can solve problems using adaptive reasoning. This student is said to have good numeracy skills because they can use adaptive reasoning.BAHASA INDONESIA ABSTRACT: Literasi dan numerasi menjadi salah satu fokus pada dunia pendidikan di Indonesia.

Abstract

Automation control systems are pivotal in the advancement of Industry 4.0, especially within vocational school settings. Nevertheless, significant challenges arise due to the lack of adequate instructional tools, resulting in disparities among vocational schools across different regions. To address this issue, this study proposes the provision of trainer kits and the conduction of comprehensive training on Programmable Logic Controllers (PLC) and Human-Machine Interfaces (HMI) to bolster practical learning experiences. Moreover, the integration of the Problem-Based Learning (PBL) approach within vocational school curricula is deemed essential. The successful implementation of PBL at the Polman Negeri Babel campus serves as a model to be replicated among vocational school teachers, with the aim of enhancing student engagement and contributing to the development of basic technological solutions within the community.This community service initiative seeks to strengthen collaboration between vocational schools and higher vocational education institutions. The anticipated outcomes include the provision of instructional tools, such as trainer modules, and targeted training on PLC and HMI to facilitate practical learning. These efforts are intended to improve the competencies of both teachers and students in industrial automation control systems, thereby underscoring the critical role of higher vocational education institutions in the development of vocational schools. Evaluation of the initiative revealed high levels of perceived usefulness, with a rating of 92.5%, followed by the effectiveness of the delivery method at 86.88%, and the quality of training materials at 80.83%. These results highlight the significant impact and value of the provided training and resources.

Abstract

The fact that gadgets are no longer luxury items and every student certainly has them presents an opportunity for teachers to create meaningful learning. One way to do this is by conducting learning assisted by PhET Simulations. These simulations offer various concepts in mathematics, physics, biology, and chemistry to be taught in the form of simulations. The use of these simulations allows the role of the teacher as a learning facilitator to be effectively carried out theoretically. However, the use of simulations has not been carried out to assist teachers in teaching material. Strengthening needs to be done. The strengthening is carried out at SMP N 1 Pemali through providing focused reinforcement for Mathematics and Natural Sciences (IPA) teachers. The reinforcement implementation is equivalent to a 6-hour training with activities starting and ending with tests to see if there is any improvement in understanding related to the reinforcement provided. Information was obtained indicating a good improvement in understanding related to the use of PhET as a learning medium for teachers is 37,5 %. In addition, the reinforcement provided received a positive response. Reinforcement practice in using PhET simulations has a good impact on MIPA SMP’s teachers as facilitators in learning.

Abstract

The factor that must be considered in the machining process is the level of surface roughness of the material being processed. Computer Numerical Control (CNC) machines help in producing large quantities of products without resetting the computer program. The process variables used in this study were feed speed with variations in levels of 140 mm/minute and 180 mm/minute, depth of ingestion with variations in levels of 0.5 mm and 0.7 mm, and feeding motion with variations in levels of 0.25 mm/put and 0.5mm/put. The analysis was carried out using the taguchi calculation method. The results of research data analysis that has been carried out on the surface roughness value of AISI 1040 steel can be determined that setting the variable settings in the CNC lathe machining process to produce the lowest surface roughness value on AISI 1040 steel material can be obtained by a combination of speed variables feed 180 m/minute (level 2), depth of feed 0.7 mm (level 2) and feed 0.25 mm/put (level 1) with a contribution value of . Where the contribution of feed motion makes the greatest contribution to the surface roughness response when compared to other factors, namely 31.3764%. The second contribution that influences the response to surface roughness is feed speed, which is 16.8977%. depth of ingestion is 5.1126%.

Abstract

Human life today is very dependent on electrical energy. In almost everyday life, people need electricity, whether in offices, households, education, industry, and others. Excessive use of electricity can cause waste both in terms of costs and energy itself. Careful monitoring is needed to find out how much electrical power is used in electronic equipment. The important thing for users to pay attention to is monitoring electrical power consumption so that the use of electronic equipment remains within the time and cost limits that have been previously set. Therefore, the aim of this research is to make it easier for users to carry out this monitoring through a website-based system. Data from the PZEM-004T sensor is processed by the ESP32 microcontroller, then sent to the database via the internet network. In this way, this information can be accessed by users anytime and anywhere via websites connected to the internet. The level of data accuracy on the website reaches 100%, according to the reading results from ESP32 and Power Quality Analyzer as a comparison.

Abstract

The snakehead fish is a type of freshwater fish that is widely cultivated due to its relatively high economic value. Achieving success in snakehead fish farming requires careful planning, effective management, understanding of cultivation techniques, and compliance with regulations and business requirements. However, temperature and pH checks in the fish pond at PT Mahkota Tanah Air are currently conducted manually. The environmental conditions of the pond significantly affect the freshwater fish farming process. Therefore, a modern technology-based detection system is needed to monitor the temperature and pH of the fish pond using the Fuzzy method. Thus, the implementation of this temperature and pH detection monitoring system can assist pond operators in monitoring the temperature and pH of the fish pond. The testing results of the temperature and pH sensors at PT Mahkota Tanah Air show an accuracy rate of 98%, indicating success.

Abstract

Attendance is an attendance list that is always used to view attendance data at an institution that wants to use it, because attendance has a value that is relevant enough to be used. In achieving data relevance for absenteeism, careful planning, effective management, and compliance with regulations and requirements are required. However, attendance at the Bangka Belitung State Manufacturing Polytechnic is still done manually. The conditions used greatly influence the technology used. Therefore, we need an attendance tool based on modern technology, namely RFID, which can be used to register attendance which is carried out by developing a system using the Prototype method. So with this RFID-based attendance system it can help the work of those in charge of managing attendance data.
