Abstract

Penelitian ini adalah penelitian deskriptif kuantitatif yang bertujuan untuk mengetahui keserempakan pemutus tenaga (PMT) 150 kV di gardu Induk Jeneponto. Dalam penelitian ini dilakukan pengujian pada kontak PMT 150 kV bay line Jeneponto-Punagaya #2 dengan mengukur keserempakan waktu kerja kontak open dan close menggunakan alat ukur Breaker Analyzer. Pengujian yang dilakukan pada pemeliharaan 2 tahunan yaitu pada tahun 2020 dan 2022. Standar SPLN NO.52-1 1984 waktu maksimum membuka dan menutup kontak PMT untuk sistem 150 kV tidak melebihi 120 ms. Dimana hasil pengujian keserempakan yang dihasilkan menggunakan breaker analyzer masih dalam batas standar PLN. Kemudian untuk hasilpengujian selisih waktu pada tahun 2020 dan 2022 juga sudah sesuai dengan standar PLN yaitu dengan selisih waktu kontak <10 ms, maka dinyatakan PMT 150 kV di Gardu Induk Jeneponto tersebut masih layak untuk digunakan. Apabila selisih waktu PMT 150 kV tidak sesuai dengan standar, salah satu penyebabnya adalah motor yang terdapat pada box kontrol PMT di kontak salah satu fasa melakukan pengisian dengan waktu pengisian motor yang lebih cepat dari kedua motor pada fasa lainnya, sehingga otomatis kekuatan mekanik penggerak dari spring (pegas) yang dimiliki oleh kontak PMT pada salah satu fasa ketika menutup kontaknya menjadi lebih kuat daripada kedua kontak pada fasa lainnya. Mengatasi permasalahan tersebut, direkomendasikan untuk melakukan penyetelan pada moving contact yang dimiliki oleh PMT 150 kV tersebut.

Abstract

Penelitian ini bertujuan untuk mengetahui kondisi tahanan isolasi pemutus tenaga kubikel 20 kV pada Gardu Induk di Jeneponto. Penelitian ini menggunakan metode penelitian deskriptif kuantitatif dengan menggunakan beberapa teknik pengumpulan data yaitu wawancara, dokumentasi dan pengukuran langsung. Dalam penelitian ini dilakukan pengukuran tahanan isolasi pemutus tenaga 20 kV bay feeder Arungkeke menggunakan alat ukur Megger. Pengukuran yang dilakukan pada pemeliharaan 2 tahunan yaitu pada tahun 2021 dan 2023. Tahanan isolasi pemutus tenaga dikatakan baik apabila sudah memenuhi standar tahanan isolasi sesuai Surat Keputusan Direksi 520/Pedoman Pemeliharaan Kubikel Tegangan Menengah Kepdir 0520-2.K.DIR.2014 “minimum besarnya tahanan isolasi pada suhu operasi dihitung 1 kV= 1 MΩ”. Dalam pengukuran ini didapatkan hasil tahanan isolasi terendah sebesar 66 GΩ, nilai ini memenuhi standar minimum tahanan isolasi pemutus tenaga yang bekerja pada tegangan 20 kV sebesar 0,02 GΩ sehingga tahanan isolasi pemutus tenaga 20 kV kubikel di Gardu Induk Jeneponto dikatakan masih sangat aman dan layak untuk dioperasikan.

Abstract

This study aimed to develop an early warning system for detecting malfunctions in three-phase electric motors using a LoRa-based microcontroller. Three-phase electric motors are vital components in industry, and their failure can cause significant downtime and financial losses. This system was designed to improve operational reliability and efficiency through remote monitoring and early detection of potential failures. Various sensors, including current, voltage, temperature, and RPM sensors, was installed on the motor to monitor its operational conditions. The collected data was sent via the LoRa network to the processing unit for further analysis and early warning. The study used Research and Development (R&D) approach with a prototyping development model, which included gathering requirements, designing, prototyping, and evaluating the system. Each stage was designed to ensure that the developed system can meet the expected operational and functional needs. It is expected that this system can prevent greater damage, reduce maintenance costs, and increase overall industrial productivity.

Abstract

The emergence of ChatGPT has fundamentally reshaped programming education while raising concerns about student over-reliance and weakened independent problem-solving. This research examines how students' attitudes toward ChatGPT including perceived utility (PU), accessibility (PEOU), capability (PC), and self-directedness (PA) influence their problem-resolution skills (PSA). The study integrates Technology Acceptance Model (TAM) with Self-Determination Theory (SDT) frameworks. Using quantitative methodology, data from 165 Informatics Education students at Universitas Negeri Makassar underwent PLS-SEM analysis. Measurement reliability was confirmed (factor loadings exceeded 0.733, AVE surpassed 0.50, CR topped 0.896, HTMT below 0.90). The structural model accounted for 70.2% variance in problem-solving capability (R² = 0.702). Three hypotheses received support: accessibility positively influenced problem-solving (β = 0.377, p < 0.001, f² = 0.138), capability showed positive effects (β = 0.334, p = 0.001, f² = 0.121), and self-directedness contributed positively (β = 0.218, p = 0.030, f² = 0.052). However, perceived utility showed no meaningful association (β = -0.017, p = 0.443). Results reveal cognitive achievement relies more on system accessibility and psychological need satisfaction than perceived utility, contradicting traditional TAM assumptions. Pedagogically, instructors should position ChatGPT as an intellectual companion enhancing critical thinking and independence rather than creating dependency. Study limitations include cross-sectional design, self-report measures, and single-institution sampling. Future research should employ longitudinal designs with objective assessments while controlling confounding variables.
