Abstract

Effective learning can be achieved by utilizing practical teaching aids that can challenge students to understand the material. This needs to be done to increase students' lack of learning motivation, as it will hurt learning achievement. Each student has a variety of learning styles, such as visual, audio, and kinesthetic. Therefore, teachers should try to create innovation by developing teaching aids in the form of a Pascal pressure model that can be implemented in learning experiments. The purpose of making this demonstration equipment is so students can understand the concept of Pascal pressure more concretely and in-depth, compared to relying on pictures as a visual tool. Apart from that, this innovation can also increase student motivation so that learning becomes more real and not just imagination and so that student learning outcomes can increase. The research method involves identifying old materials that can be used, designing creative and educational teaching aids, as well as testing the effectiveness of teaching aids in supporting science learning. The research results show that using used materials in natural science teaching aids can reduce negative environmental impacts by reducing waste and consuming new resources. The teaching aids developed can also facilitate understanding of science concepts visually and interactively. The trial of this teaching aid showed a positive response from students toward a more interesting and sustainable learning method.

The scale also varies, ranging from simple household appliances to heavy industrial equipment. In the process of collecting household electrical power, a kWh Meter is needed to simplify and minimize employee errors in inputting data on household and industrial electricity usage in the Medan City area. In its operation, operational and non-operational disturbances often occur such as congestion at the kWh meter, fire at the kWh meter, and other unavoidable disturbances. In overcoming disturbances that occur in kWh Meters, Inspection and Maintenance of kWh meters can be carried out, especially on digital / Postpaid kWh Meters. This report contains the type of kWh that is often used, the components in the kWh meter, the types of disturbances that often occur in the kWh meter, the impact on the damage to the kWh meter, and how to overcome these types of disturbances.

Abstract

Malus' law asserts that the square of the cosine of the angle formed between two polarizers is directly proportional to the intensity of light after passing through them. In this study, we demonstrate this law using a straightforward configuration. Our method of measuring the polarizer's rotational angle while keeping the other polarizer stationary is innovative. It involves manually attaching a multi-turn potentiometer to one of the polarizers. The Arduino board is connected to the potentiometer and light sensor that is used to detect the intensity of transmitted light, allowing for the measurement of light intensity as a function of rotational angle. Additionally, we think that the configuration as it is now can be helpful in physics laboratory classes. It can also be demonstrated by using it during lectures

Abstract

Keandalan operasi transformator sangat tergantung pada kondisi isolasi yang baik. Penelitian ini bertujuan untuk menganalisis tahanan isolasi dan mengestimasi umur transformator dengan menggunakan metode Health Index di PT PLN (Persero) UPT Cawang. Metode Health Index ini mengintegrasikan berbagai parameter kondisi transformator, termasuk hasil pengukuran tahanan isolasi, pengujian minyak isolasi, dan parameter operasional lainnya, untuk memberikan gambaran komprehensif tentang kondisi kesehatan transformator. Data diperoleh dari pengujian lapangan dan laboratorium yang dilakukan secara periodik. Hasil analisis menunjukkan bahwa beberapa transformator memiliki nilai tahanan isolasi yang mendekati batas minimal yang direkomendasikan, mengindikasikan adanya penurunan kualitas isolasi. Estimasi umur transformator dilakukan berdasarkan nilai Health Index yang dihitung, dengan mempertimbangkan degradasi material isolasi dan kondisi operasional transformator. Transformator dengan nilai Health Index yang rendah diidentifikasi memiliki risiko tinggi terhadap kegagalan operasional dan memerlukan tindakan pemeliharaan atau penggantian segera. Studi ini memberikan wawasan penting bagi manajemen pemeliharaan di PT PLN (Persero) UPT Cawang untuk meningkatkan keandalan dan efisiensi operasi transformator. Implementasi metode Health Index terbukti efektif dalam memprediksi umur sisa transformator dan merencanakan strategi pemeliharaan preventif. Dengan demikian, dapat diharapkan peningkatan kontinuitas layanan penyaluran energi listrik dan pengurangan risiko gangguan operasional.   Kata kunci: Estimasi Umur, Health Index, Pemeliharaan Preventif, Tahanan Isolasi, Transformator.

Abstract

The use of shore connection services at tanker berths is an important innovation to increase energy efficiency and reduce greenhouse gas emissions in the maritime sector. This research analyzes the technical aspects of implementing shore connections, including system configuration, integration with port infrastructure, as well as operational and economic challenges. This study uses a descriptive analysis method with data collected through field observations, interviews with port operators, and a review of related literature. The research results show that the implementation of shore connections is able to reduce fuel consumption and pollutant emissions significantly. However, there are obstacles such as high initial investment costs, the need for international technical standards, and adjustments to ship operations. Recommendations include increasing cooperation between ports and shipowners, as well as developing incentive policies to encourage the adoption of this technology. This research provides valuable insights for stakeholders in efforts to achieve more sustainable shipping.

Abstract

This research aims to improve the performance of a-Si: H solar cells, particularly in terms of carrier transport properties, through a numerical design approach utilizing AFORS-HET simulation software. By performing a series of rigorous computer simulations, we explore the potential regulation of the intrinsic layer thickness, carrier mobility, loading factor, and density of states (DoS) distribution in the solar cell's intrinsic layer. Recombination losses are reduced, and light absorption efficiency is significantly increased when the intrinsic layer thickness is adjusted, as shown by simulation findings. Moreover, reduction of transit times and enhancement of the total efficiency of the solar cells depend on increased carrier mobility. Parameters can be adjusted to attain optimal performance under various operating situations by adjusting the DoS and load factors. Furthermore, the simulations provide insightful information about the interactions between the junctions in solar cells with double junctions. Our results of this research provide an important contribution to efforts to develop more efficient and sustainable a-Si: H solar cells and emphasize the importance of numerical design approaches in photovoltaic technology.
