Abstract

Distribution of electricity to consumers through some process that begins from power plants to substations supplied (sub-station), then lowered into the substation -a low-voltage distribution substations. The distance is too far between the point on the voltage distribution in particular between the IBT to the parent distribution substation secondary voltage drop triggers, It is as well as on the distance between new or IBT IBT cilegon Gandul to trigger serpong substation secondary voltage drop at substation serpong.To stabilize the voltage of the secondary to the primary voltage on distribution transformer tap changer operation. Problems arise when the tap changer to operate too much will lead to the over-excitation of the distribution transformer. The side effects of the over-excitation also trigger an increase in temperature of the thermal transformer, so the effect on the components within it, is no exception to the isolation of paper inthe process of thermal temperature rise is accelerating aging insulating paper it self. The exixtence of aging insulating paper must be accompanied by the estimated number of clear that the replacement of aging insulating paper on time, so it requires the calculation of accurate data on the thermal temperature kenaiakan to aging transformer paper insulation.Keywords: electricity distribution process, reduced secondary voltage, over-excitation, aging insulating paper, the estimated value.

Abstract

Qualitative research relies on both primary and secondary data. This research aims to elucidate the implementation of green supply chain management in the tempeh industry, as well as to illustrate how green supply chain management can be applied to effectively manage waste generated by the tempeh industry. The ultimate goal is to promote environmental sustainability and mitigate the issue of industrial waste, thereby ensuring a clean and healthy environment. The findings of this study indicate that the integration of green supply chain management in the tempeh industry has been effectively executed. The utilization of raw resources also aligns with the concepts of green supply chain. In addition to that, there is excellent cooperation within the supply chain. Nevertheless, there are still areas for improvement in the supply chain flow of the green supply chain implementation in the tempe business in North Jakarta. Additional empirical study is required to examine the aspects that contribute to the performance of green supply chains.

Abstract

Pembelajaran konvensional mengenai konsep ekologi yang abstrak, seperti rantai makanan, seringkali menjadi tantangan bagi siswa Sekolah Dasar (SD) kelas V, yang dapat mengakibatkan rendahnya motivasi dan pemahaman. Penelitian ini bertujuan untuk merancang antarmuka pengguna (User Interface - UI) sebuah aplikasi pembelajaran berbasis mobile yang inovatif untuk mengatasi masalah tersebut. Metode perancangan yang digunakan adalah Design Thinking, sebuah pendekatan yang berpusat pada pengguna dan terdiri dari lima tahapan: Empathize, Define, Ideate, Prototype, dan Test. Aplikasi yang dirancang mengintegrasikan tiga fitur utama: materi pembelajaran interaktif, kuis evaluatif, dan minigames yang edukatif untuk meningkatkan keterlibatan siswa. Proses perancangan menghasilkan sebuah prototipe interaktif berketelitian tinggi (high-fidelity) yang kemudian diuji pada target pengguna. Hasil uji ketergunaan (usability testing) menunjukkan respons yang sangat positif dari siswa, yang mengindikasikan bahwa desain aplikasi berhasil memenuhi kebutuhan dan preferensi mereka, serta efektif dalam menyajikan materi pembelajaran. Penelitian ini memberikan kontribusi pada pengembangan teknologi pendidikan dengan menyajikan model perancangan aplikasi pembelajaran IPA yang interaktif dan menarik bagi anak-anak
