Abstract

This study aims to analyze the operational condition of the distribution transformer at substation PY094, PLN ULP Pringgabaya, with a primary focus on identifying and calculating the level of load imbalance on the consumer side. Data were collected through direct measurements of electrical parameters, including voltage and current in each phase, followed by a detailed analysis of energy losses. The measurement results indicated a significant load imbalance. In Feeder B, the average phase currents were recorded at 103.8 A for phase R, 130.2 A for phase S, and 90.4 A for phase T. Meanwhile, in Feeder D, the average phase currents were 47.4 A for phase R, 18 A for phase S, and 20.4 A for phase T. This imbalance caused notable power losses in the distribution system, with an estimated daily energy loss of 28.94 kWh, assuming the system operates 12 hours per day. To address this issue, load balancing simulations were carried out using ETAP software. The simulation involved redistributing load values across each phase in the two main feeders. Feeder B was simulated at 46.82% of the transformer’s full capacity, while Feeder D was simulated at 12.38% of the total 160 kVA capacity. The simulation results demonstrated that redistributing the load significantly reduced the current imbalance, thereby minimizing power losses and improving the operational efficiency of the distribution substation. Therefore, load balancing strategies are essential for enhancing energy efficiency and ensuring the reliability of electricity supply in distribution networks.

Abstract

The Indonesian government's policy of deactivating analog television broadcasts and switching to digital television has an impact on people who are still used to enjoying analog television broadcasts. Moreover, many television devices owned by the public are still analog system televisions. Thus, people need devices that can convert analog signals into digital form and can be displayed on analog television. This device is better known as a Set Top Box (STB). Unfortunately, people only use STB to watch digital TV shows, while STB has many features that can be used to obtain information, communication tools and entertainment media. For this reason, it is necessary to transfer knowledge and technology to the community so that it can optimize the functions and features of the STB, then these activities are packaged in the form of Community Service. The results of the activity showed that the public was very enthusiastic in following and concerning to the presentation of information on STB features, proven by the large number of people who attended, reaching 93% of the invitations given, and the many questions asked during the discussion session.

Abstract

This study examines the implementation of the Permissive Overreach Transfer Trip (POTT) Echo scheme with the activation of the Weak-End Infeed (WEI) function on distance protection systems in a 150 kV transmission network to enhance protection reliability and selectivity, especially at substations with weak infeed currents. Before WEI activation, the protection system experienced delays or failures in detecting faults, particularly for faults in zone 2, where the relay tripped with a delay instead of achieving a desired reclose, thereby extending the Transmission Line Outage Duration (TLOD). After WEI activation, test results showed that the relay provided an instantaneous trip response, and the autoreclose function operated after 1000 ms, significantly reducing TLOD. The success of the echo signal ensured smooth communication between relays, supporting efficient protection coordination. Moreover, the selectivity function remained intact. The implementation of this scheme has proven to enhance the reliability of the protection system, offering a more stable and responsive solution for addressing the challenges posed by weak infeed currents.   Keywords: POTT, Echo, Weak-End Infeed, Distance Protection, Autoreclose   ABSTRAK Penelitian ini membahas implementasi skema Permissive Overreach Transfer Trip (POTT) Echo dengan aktivasi fungsi Weak-End Infeed (WEI) pada sistem proteksi jarak di jaringan transmisi 150 kV untuk meningkatkan keandalan dan selektivitas proteksi, khususnya di gardu induk dengan arus infeed lemah. Sebelum aktivasi WEI, sistem proteksi mengalami keterlambatan atau kegagalan dalam mendeteksi gangguan, terutama pada gangguan di zona 2, di mana relay memicu trip dengan waktu tunda, meskipun reclose diharapkan, sehingga memperpanjang durasi gangguan (Transmission Line Outage Duration - TLOD). Setelah aktivasi WEI, hasil pengujian menunjukkan bahwa relay memberikan respon trip instan, dan fungsi autoreclose dapat bekerja setelah 1000 ms, mengurangi TLOD secara signifikan. Keberhasilan sinyal echo memastikan komunikasi antar relay berjalan lancar, mendukung koordinasi proteksi yang efisien. Selain itu, fungsi selektivitas tetap terjaga. Penerapan skema ini terbukti meningkatkan keandalan sistem proteksi, memberikan solusi yang lebih stabil dan responsif dalam menghadapi tantangan arus infeed lemah.

Abstract

Pada gardu induk terdapat transformator tenaga yang berfungsi menurunkan tegangan tinggi ke tegangan menengah. Transformator tenaga memiliki sistem proteksi berupa relai elektrik dan mekanik sebagai pengaman pada transformator. Salah satu proteksi mekanik transformator tenaga yaitu proteksi temperatur dengan pengaman berupa relai termal yang kerjanya dipengaruhi suhu minyak maupun suhu belitan. Pada proteksi termal ini memiliki potensi yang cukup tinggi terhadap gangguan nonsistem bay trafo. Maka dilakukan modifikasi rangkaian alarm dan trip pada relai termal untuk mencegah terjadinya gangguan nonsistem bay trafo. Tugas akhir ini membahas mengenai modifikasi rangkaian alarm dan trip pada proteksi temperatur Transformator 2 Gardu Induk Blora dengan penambahan auxiliary relay untuk mengamankan jalur tripping. Penambahan auxiliary relay tersebut dimaksudkan untuk memutus arus yang menuju ke jalur tripping agar tidak mengerjakan kontak trip apabila terjadi short terminal maupun kerusakan  ada relai bantu. Dalam penerapannya modifikasi ini memiliki manfaat dari segi finansial terkait keefektifan biaya apabila terjadi gangguan dan dari segi non finansial dapat mengurangi potensi gangguan pada transformator akibat gangguan nonsistem bay trafo, serta dapat menambah keandalan transformator dalam menyalurkan energi listrik..Keywords :Modifikasi, Relai Termal, Transformator, Gangguan Nonsistem.

Abstract

Component-Level Domestic Content Policy (TKDN) encourages the utilization of domestically produced medical devices; however, their accuracy and safety must be proven. This study aims to analyze the accuracy of domestic infusion pumps using the uncertainty measurement method. A total of four units from four brands (Endo, ESA Tech, Inmedik, and Krisma Care) were tested on the flow rate parameter with variations of 10, 50, 100, 200, and 300 mL/hour. Each test point was measured six times using a calibrated Fluke IDA 5 Infusion Device Analyzer. Data were analyzed through calculations of mean, correction, standard deviation, and expanded uncertainty (k = 2). Based on the analysis results, all TKDN infusion pumps (100%) met the tolerance limit of ±10% in accordance with the PO.002-18 standard and were declared fit for use. The highest correction value of 25.57 mL/hour (8.5%) was recorded for the Endo brand at a setting of 300 mL/hour, while the lowest correction of 0.21 mL/hour (0.7%) was found in ESA Tech. All measurement points across the four brands showed consistency within the permitted tolerance limits, with measurement uncertainty variations between ±0.15 and ±0.17 mL/hour. These findings prove that domestically produced infusion pumps possess accuracy and reliability equivalent to the standards required for clinical use.

Abstract

This study evaluates the accuracy of locally manufactured syringe pumps used in Karanganyar District Hospital and analyzes their measurement uncertainty based on the ISO GUM method. Five Indonesian brands (Endo, Esa Tech, Inmedik, KalTech, and Krisma) were tested using an Infusion Device Analyzer at three flow-rate set-points (10, 50, and 100 ml/h) and an occlusion test at 100 ml/h. All devices met the standard tolerance limits (±10% and <20 psi). The expanded uncertainty ranged from ±0.09 to ±0.70 ml/h, indicating reliable measurement performance. KalTech and Inmedik demonstrated the most stable accuracy, while Esa Tech tended to over-read at low flow rates and Krisma showed significant under-reading at high flow rates, though still within acceptable limits. Statistical tests confirmed no significant differences among brands. Overall, the findings support that Indonesia-made syringe pumps meet technical requirements and strengthen the implementation of the national TKDN policy for reducing dependence on imported medical devices.

Abstract

Monitoring cardiovascular patients at home is often constrained by the interpretation of raw sensor data. This service aimed to implement a portable decision support system to convert raw heart rate (BPM) and oxygen saturation (SpO2) data into meaningful health condition information. The method used was designing a prototype based on NodeMCU ESP8266 and the MAX30100 sensor for data acquisition , and applying Mamdani Fuzzy Logic for analysis. A Fuzzy Inference System (FIS) in MATLAB used 9 rule-bases to classify 2 inputs (BPM and SpO2) into 3 outputs ('Healthy', 'Caution', 'Emergency'). The case study object was a patient with a history of hypertensive heart disease and aortic aneurysm. The results showed the prototype had high accuracy, reaching 95.98% for heart rate and 95.31% for oxygen saturation. The fuzzy logic system successfully classified 35 test datasets, with 34 detected as "Healthy" and 1 as "Caution," proving its sensitivity in monitoring. Oxygen saturation was proven to be the dominant factor for 'Emergency' conditions, while heart rate more influenced the transition from "Healthy" to "Caution". This system provides a practical solution for families to monitor patient conditions more effectively.
