Abstract

The demand for reliable and environmentally friendly electricity supply has driven the development of more efficient backup power systems. This study aims to design and construct a hybrid power generation installation that combines thermoelectric generators and solar panels as a backup power solution. The system utilizes solar radiation and temperature disparity as primary energy sources, which are then converted into electrical energy and stored in a 200 Ah LiFePO4 battery. The design stages include the selection of key components such as thermoelectric modules, 100 Wp solar panels, maximum power point trackers, battery controllers, and inverters. Simulations and tests were carried out to analyze the system’s performance under the climatic conditions of Medan City. The test results indicate that power can be continuously generated from these two energy sources, providing a stable backup electricity supply. With a modular and efficient structure, this system has the potential to serve as a sustainable energy source that reduces dependence on fossil fuels. This design also holds promise as a prototype for educational purposes and a rapid solution during power outages.

Abstract

Perilaku kekerasan yang dilakukan senior terhadap junior di lingkungan pendidikan masih banyak dijumpai di berbagai sekolah dan universitas, khususnya di lingkungan pendidikan yang menggunakan sistem sekolah berasrama (boarding school). Penelitian ini bertujuan untuk melihat terkait dengan faktor yang melatarbelakangi perilaku kekerasan yang dilakukan senior terhadap junior di lingkungan pendidikan. Selain menganalisis faktor yang melatarbelakangi kekerasan, penelitian ini juga bertujuan untuk mengetahui bagaimana tindak kekerasan di lingkungan pendidikan yang menggunakan sistem sekolah berasrama dapat terjadi, cara pencegahannya dan juga kendala yang dihadapi dalam upya pencegahan tindak pidana kekerasan tersebut. Metode penelitian yang digunakan adalah yuridis normatif yaitu dengan menggunakan peraturan perundang-undangan. Sumber data yang digunakan dalam penelitian ini yaitu melalui literatur dari berbagai jurnal, buku dan website yang sesuai dengan topik yang dibahas. Hasil dari penelitian ini menyimpulkan bahwa faktor yang menyebabkan kekerasan yang dilakukan senior ke junior di lingkungan pendidikan yang menggunakan sistem pesantren atau asrama. Dengan demikian untuk dapat menekan terjadinya kekerasan terhadap junior di lingkungan pendidikan dengan sistem asrama atau pesantren perlu dilakukan evaluasi yang mendalam mendalam mengenai pentingnya pendidikan dengan sistem pesantren (boarding school) terkait dengan mutu pendidikan.

Abstract

This study aims to design and develop a kinetic power generation device that utilizes the mechanical energy from pedestrian foot pressure on sidewalks. The working principle of the system is to convert mechanical energy into electrical energy using eight 12V DC car central lock actuators arranged in a series-parallel configuration. The electrical energy generated from foot pressure is directed into an electronic circuit consisting of diodes as reverse current protection, a DC-DC step-down converter to reduce voltage, and a charge controller to regulate the charging process of a 6800 mAh lithium-ion battery. The stored energy is then boosted using a DC-DC step-up converter to match the load requirements, which is a 10W LED lamp operating at 5V DC. To support monitoring, the circuit is equipped with a control panel containing a digital voltmeter and ammeter with an LCD display that shows voltage and current conditions in real time. All components are regularly assembled inside a panel box mounted on a mini light pole, ensuring practicality and safety in operation. The test results show that the device is capable of producing an average maximum voltage of 14.83 V with a current of up to 25 mA when all central lock actuators are pressed simultaneously. The stored energy in the battery can be used to power the LED lamp for several hours, depending on the intensity and frequency of pedestrian footsteps. With its simple design, easily obtainable components, and relatively low production cost, this system has the potential to serve as an alternative solution in supporting energy efficiency and the application of renewable energy-based lighting systems in campus environments as well as other public areas

Abstract

This study aims to analyze the influence of digital literacy levels on the productivity of educators at the Medan Aviation Polytechnic, considering the demands of technological developments in the Society 5.0 era that require educators to master various digital skills to support the Tridharma of Higher Education. Using a quantitative descriptive method through a survey of 50 educator respondents (total sampling), this study measures four pillars of digital literacy: Digital Skills, Digital Ethics, Digital Safety, and Digital Culture. The results show that the four dimensions of digital literacy have a significant and positive influence on educator productivity (p-value 0.000 < 0.05). Specifically, Digital Culture is the variable that has the greatest influence, with a tendency of 49-fold influence on increasing educator productivity at the institution.
