Abstract

Abstract - Voltage stability is the main prerequisite for electrical equipment to operate safely and reliably. This research design builds a single-phase protection system against overvoltage conditions. It is based on the Arduino Uno microcontroller with a time-lag relay scheme. The PZEM-004T sensor reliably monitors the input voltage of 80-260 V AC and sends the data using the UART communication protocol to the Arduino for analysis against the 192 V and 231 V thresholds. When the voltage exceeds these limits, the Arduino will automatically trigger a 5 V DC relay after a programmed time delay. This ensures that transient disturbances do not trigger premature disconnection of power. A 16x2 I2C LCD interface and three push-buttons allow users to monitor real-time voltage as well as set overvoltage, time-delay and calibration offset limits. Testing of the design results showed that the system successfully disconnected and connected the load according to the parameters, with a voltage reading error of < 1% after calibration and a trip time deviation below 10% of the set point. The research design, using easily accessible components, effectively teaches the principles of overvoltage protection relays, despite technical limitations. Keywords − overvoltage, time-lag relay, arduino, voltage protection.

Abstract

Meningkatnya tantangan intoleransi dan polarisasi sosial dalam masyarakat multikultural Indonesia memerlukan respon pendidikan yang strategis. Penelitian ini bertujuan untuk menganalisis implementasi kebijakan pendidikan multikultural sebagai fondasi dalam membangun sikap toleransi di lingkungan sekolah. Menggunakan metode studi pustaka (library research) dengan pendekatan deskriptif-kualitatif, penelitian ini menyintesis temuan dari sepuluh jurnal ilmiah kontemporer. Hasil kajian menunjukkan bahwa pendidikan multikultural diimplementasikan secara efektif melalui integrasi kurikulum sistemik pada mata pelajaran PPKn dan Pendidikan Agama Islam, penerapan model pembelajaran interaktif-humanis, serta penciptaan budaya sekolah yang inklusif. Meskipun demikian, hambatan signifikan masih ditemukan, meliputi keterbatasan kompetensi pedagogis guru dalam perspektif multikultural dan kurangnya materi ajar yang representatif. Penelitian ini menyimpulkan bahwa sinergi holistik antara pembuat kebijakan, pendidik, dan masyarakat sangat krusial untuk menginstitusikan nilai-nilai multikultural sebagai upaya preventif konflik sosial sekaligus fondasi keharmonisan bangsa.

Abstract

This study aims to analyze school principal leadership management in increasing teacher motivation at SMK Assa’adah Bungah Gresik. This research uses a qualitative approach with a descriptive type. The research subjects include the school principal and teachers, with data collection techniques through observation, in-depth interviews, and documentation. Data analysis uses the Miles and Huberman interactive model which includes data reduction, data presentation, and conclusion drawing. The results show that school principal leadership management at SMK Assa’adah Bungah Gresik is implemented through four management functions, namely planning that integrates vocational goals and Islamic values, organizing through clear division of tasks, actuating with democratic and exemplary leadership styles, and controlling in the form of coaching. Teacher motivation is driven by intrinsic factors in the form of spiritual awareness of teaching as worship, and extrinsic factors in the form of responsive leadership support. The integration of these managerial functions has proven effective in creating a conducive work climate and increasing teacher work motivation holistically in a pesantren-based vocational school environment. This research provides a theoretical contribution by strengthening the concept of principal leadership management based on the integration of Islamic values and the managerial function of POAC in improving teacher motivation. Practically, this research provides an implementation model for principals, particularly in Islamic boarding school-based vocational schools (SMK), in creating a conducive work climate and increasing teacher motivation in a sustainable manner.

Abstract

Vocational education plays a crucial role in preparing a skilled workforce that meets the demands of the labor market. Technological advances in the Industrial Revolution 4.0 era require responsive, creative, and vocational education policies that align with industrial developments. However, several studies indicate that there is still a gap between the abilities of vocational education graduates and the skills needed in the labor market. Furthermore, the implementation of vocational education policies in Indonesia is considered to be underperforming due to various structural and operational constraints. This study aims to analyze the orientation of vocational education policies in responding to the demands of the workforce, identify key challenges in policy implementation at the national level and in field practice, and evaluate their level of alignment with workforce competency needs in the Industrial Revolution 4.0 era. This study applies a qualitative approach through library research with descriptive analysis of various policy documents, scientific articles, and relevant previous research findings. The research findings indicate that vocational education policies in Indonesia still face several key challenges, including a lack of coordination between stakeholders, inadequate human resources and educational infrastructure readiness, and a suboptimal link between the education curriculum and industry needs. Thus, it is important to strengthen cooperation between the government, educational institutions, and the industrial sector so that vocational education policies can be more efficient in producing a qualified and competitive workforce.   Keywords: World of Work, Policy Implementation, Vocational Education Policy, Industrial Revolution 4.0, Literature Study

Abstract

Education is a fundamental right of every citizen guaranteed in the Indonesian constitution, particularly in the 1945 Constitution of the Republic of Indonesia, Article 31. The Indonesian government has issued various policies to improve the quality of primary and secondary education while ensuring equitable access and quality across all regions. Nevertheless, the disparity in education quality between urban and rural areas, as well as between western and eastern regions of Indonesia, remains a serious challenge. This article aims to analyze primary and secondary education policies from the perspective of quality equity, identify factors hindering policy implementation, and formulate strategic recommendations for improvement. The study uses a literature review method with a descriptive-analytical approach through the examination of regulations, government reports, and previous research findings. The analysis results show that policies such as the School Operational Assistance (BOS), the Indonesia Smart Program (PIP), and the Merdeka Curriculum have improved access to education and learning flexibility. However, disparities in teacher distribution, limited infrastructure, as well as weak oversight and policy evaluation remain major obstacles in equalizing the quality of education.   Keywords: Education Policy, Quality Equalization, Primary Education, Secondary Education

Abstract

The escalating demand for sustainable energy solutions within the automotive industry has catalyzed extensive research into alternative methodologies for energy harvesting. This investigation examines the feasibility of thermoelectric energy harvesting from disc brake systems utilizing the SP1848-27145 SA thermoelectric generator (TEG) module. The selection of the SP1848-27145 SA module is predicated on its dependable electrical output when subjected to moderate temperature differentials characteristic of disc brake operations, in conjunction with its compact and lightweight configuration, which renders it amenable for integration into vehicles.A laboratory-scale apparatus emulating a disc brake system was constructed, and a series of experimental tests alongside computational simulations were conducted to assess the efficiency of the conversion from thermal to electrical energy. Braking loads ranging from 1.5 to 2.25 kg were exerted over intervals of 50 seconds, resulting in disc temperatures ascending to 114.8 °C. The maximum output voltage recorded was 0.57 V. Numerical simulations executed with ANSYS 19.2 corroborated the experimental findings, exhibiting a deviation of less than 1%. The maximum power output realized was 185.4 mW under optimal conditions, with a conversion efficiency fluctuating between 4% and 6%.These results underscore the potential applicability of TEGs in facilitating micro-energy systems within the automotive sector. Furthermore, the findings suggest that enhancements in thermal interfaces and optimized cooling techniques could enable this configuration to function as a sustainable auxiliary energy recovery system for hybrid and electric vehicles.
