Abstract

The 110VDC supply at the substation serves as a supply for the control and protection system at the cubicle panel. In addition, the 110VDC battery used as a backup supply plays an important role when the main supply source is lost. Loss of supply 110VDC is fatal to the electrical system. Causes electrical interference cannot be monitored and protection failure. 110VDC batteries may experience voltage drops. There are several ways to keep the battery in good condition when used, one of them with a charging system which functions to maintain the condition battery. This system uses a Buck converter circuit with charging pulses through the duty cycle can distribute high electric current to battery. With a Buck converter output voltage of 111 Volt 6.54 A at duty cycle 55% using dummy load. Test results with a voltage of 110VDC and a current of 5A in testing with dummy load of 10Ω480W obtained voltage output of 103VDC and current of 8.40A, in testing with dummy load of 10Ω400W received voltage output of 136VDC and current of 6.28A, in testing with dummy load of 12Ω500W received voltage output of 122VDC and current of 6.00 A, in testing with dummy load of 15Ω500W received voltage output of 127VDC and current of 5.88 A, in testing with dummy load of 11Ω500W received voltage output of 111VDC and current of 6.54A. From the overall test data by providing a load in the form of a dummy load, an average error of 9.86% was obtained.

Abstract

This community engagement program aims to enhance the productivity and hygiene of household-scale tempe production by automating soybean dehulling and implementing Good Manufacturing Practices (GMP), complemented by strengthened business management. The participatory action approach comprised installation and commissioning of a soybean dehulling machine, GMP implementation sessions with MSME partners, and assistance in obtaining the Business Identification Number (NIB). A pre–post evaluation assessed production capacity (kg/day), cycle time and dehulling yield, GMP compliance, and legal status. The machine was installed and operated stably; dehulling cycle time decreased, dehulling yield was high (≥85%), and daily capacity increased from approximately 30–40 kg/day to 80–100 kg/day. Training produced a hygienic SOP that is followed with routinely completed checklists, alongside indications of reduced product defects. The issuance of the NIB strengthened partners’ readiness to access formal markets and government support. These findings affirm that an integrated techno-managerial intervention effectively improves performance and product quality in Tempe production and is suitable for replication, with emphasis on machine fine-tuning and strict adherence to GMP.

Abstract

At the company PT. PLN (Persero) ULTG Madiun carried out many tests relay, one of which is intertrip testing relay distance. Intertrip testing relay distance is a test carried out between 2 (two) relay distance conducting bays in main substations that face each other. Intertrip testing relay distance must be done if replacement occursrelay, replacement of teleprotection equipment, changes to protection schemes, and changes to logic circuitsrelay which is related to the send or receive signal from the opposite substation. However, this test requires synchronization between two intertrip test tools relay distance at each substation. In this final project, it will be designed Time Syncronization As A Tool For Intertrip Relay Distance Testing, to make things easier for PT employees. PLN (Persero) ULTG Madiun when synchronizing two intertrip test equipment relay distance. All process control of this tool uses ESP32 Devkit V1. Meanwhile for displaying setting time for testing can be seen on the web assisted by GPS NEO-6M. The results obtained when testing the Dolopo by Ponorogo R and S phase distance intertrip relay were carried out at 12.00.00, experiencing a delay time of 0.0553 seconds when the PMT tripped. Meanwhile, the Dolopo by Ponorogo T phase distance intertrip relay test was carried out on 12.09.00 and experienced a delay of 0.0529 seconds when the PMT tripped. From two intertrip relay distance tests, the trip time delay is no more than 0.1 second.

Abstract

Biaya produksi merupakan hal yang harus diperhatikan dalam suatu industri. Biaya produksi tersebut disebabkan salah satunya karena kualitas daya seperti faktor daya dan rugi-rugi daya. Pemakaian beban induktif seperti motor induksi dan tranformator dapat menyebabkan kelebihan pemakaian daya reaktif, dan akan berdampak pada meningkatnya denda PLN yang harus dibayar apabila power factor < 0,85. Hal ini dapat diatasi dengan pemasangan beban yang bersifat kapasitif seperti kapasitor bank untuk menurunkan biaya pemakaian KVAR dan meminimalisir drop tegangan. Tujuan penelitian ini adalah pengoptimalan penggunaan kapasitor bank menggunakan PLC. Stepping otomatis menggunakan cos φ meter sebagai input analog PLC yang akan digunakan untuk penentuan metode yang sesuai dan mengaktifkan kapasitor. Stepping manual dilakukan dengan menekan tombol switch untuk mengaktifkan kapasitor. Hasil dari pengujian, baik stepping manual maupun otomatis sesuai dengan program PLC dan display. Metode sudah dapat bekerja secara otomatis dan penentuan akan sesuai dengan kombinasi kapasitor. Dengan hasil cos φ pada motor 1 yang awalnya sebesar 0,56 menjadi naik sebesar 0,86, pada motor 2 nilai cos φ yang awalnya sebesar 0,74 menjadi naik sebesar 0,93, pada motor 3 nilai cos φ yang awalnya sebesar 0,6 menjadi naik sebesar 0,97 dan pada motor 4 nilai cos φ yang awalnya sebesar 0,65 menjadi naik sebesar 0,95

Abstract

This study investigates a practical method to enhance the efficiency of a campus electrical distribution system by optimizing the control and power circuitry of a capacitor bank panel. The research addresses the persistent issue of low power factor and phase imbalance resulting from non-standard wiring configurations in existing installations. Unlike conventional maintenance procedures, the proposed rewiring strategy systematically redesigns the control and power connections to ensure accurate capacitor switching and reactive power compensation in accordance with operational load variations. A diagnostic improvement evaluation framework was employed, involving pre- and post-rewiring measurements of power factor, load current balance, and reactive power under both normal and full-load conditions. The rewiring intervention increased the power factor from 0.97 to 0.99 during normal operation and from 0.70 to 0.95 under full-load simulation (1100 kVA). These improvements corresponded to a measurable reduction in reactive power demand and overall system losses, indicating a substantial gain in energy efficiency and voltage stability. The findings confirm that targeted control circuit reconfiguration can significantly enhance the operational reliability of capacitor bank systems beyond conventional maintenance practices. This work contributes a replicable, technically validated approach for improving power quality in educational and industrial electrical installations.
