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

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.

Abstract

Clean water distribution in the Community-Based Drinking Water Supply and Sanitation Program (PAMSIMAS) in Kuwasen Lama Village, Gunungpati District, Semarang City, faces the challenge of unequal supply between highland and lowland areas. The main factors that affect these conditions include differences in topography, suboptimal piping network design, and unbalanced water pressure, especially during peak hours. This research proposes a solution based on Internet of Things (IoT) technology using the ESP32 module as a control center, which is integrated with the Blynk application for real-time monitoring and control of the system. The system is equipped with a water flow sensor, water level sensor, motorized valve, and booster pump to increase water pressure in high elevation areas. Two design schemes were tested, namely flow regulation using a motorized valve, and a combination of a motorized valve with a booster pump. The results of the simulation and implementation showed an increase in water pressure stability, equitable distribution, and a decrease in the frequency of supply disruptions. The system also allows for live monitoring of network conditions, facilitates technical decision-making, and improves operational efficiency. With an adaptive and community participation-based approach, this solution has the potential to become a model for PAMSIMAS clean water distribution management that is efficient, sustainable, and responsive to geographical challenges, while strengthening the resilience of clean water services in rural areas.

Abstract

Oxygen is vital therapy where delivery accuracy is crucial, especially for infant patients, to ensure treatment effectiveness and prevent the risks of hypoxia or toxicity. With the implementation of the mandatory Domestic Product Utilization Policy (TKDN+BMP ≥ 40%), evaluating the quality of local products has become an urgent necessity. This study aims to test and analyze the quality and accuracy of domestically produced infant oxygen flowmeters compared to an imported product. The method used was experimental testing, measuring three brands of domestic products and one brand of foreign product at flow rate settings of 0.5, 1, 1.5, and 2 liters per minute (LPM). Each setting point was measured 10 times using a standardized calibrator to ensure data reliability. The measurement results were analyzed to identify the deviation level of each product. The findings of this study are expected to provide an objective conclusion on the quality equivalence of domestic products with imported ones and to identify which product has the lowest deviation rate. This can serve as scientific consideration for hospitals in selecting high-quality infant oxygen flowmeters, thereby supporting the domestic product policy.

Abstract

Abstrak – Stasiun pompa air konvensional di DKI Jakarta, seperti Stasiun Pompa Cideng, seringkali tidak efisien karena mengandalkan sistem kontrol On/Off yang reaktif berbasis satu sensor dan tidak memiliki manajemen beban pompa. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sebuah prototipe sistem kontrol otomatis yang adaptif, antisipatif, dan andal untuk enam unit pompa air. Metode yang digunakan adalah Perancangan Sistem yang mengintegrasikan tiga teknologi utama. Arsitektur sistem ini menggunakan strategi dual-microcontroller, di mana Arduino Mega 2560 berfungsi sebagai unit kontrol utama (menjalankan Logika Fuzzy dan rotasi) dan ESP32 berfungsi sebagai gateway IoT. Logika fuzzy dengan 27 aturan digunakan untuk memetakan tiga variabel masukan (curah hujan, debit sungai, tinggi muka air) menjadi enam keluaran biner (On/Off) secara individual, satu untuk setiap pompa. Status siaga (normal, waspada, siaga, dan bahaya) kemudian ditentukan berdasarkan jumlah pompa yang aktif sebagai indikator. Untuk keandalan jangka panjang, diimplementasikan mekanisme rotasi pompa 7 hari berbasis RTC DS3231 yang dirancang untuk pemerataan beban kerja. Hasil pengujian prototipe pada empat skenario pengujian (normal, waspada, siaga, dan bahaya) menunjukkan sistem berhasil merespons secara proporsional dengan mengaktifkan kombinasi pompa yang tepat (0, 2, 3, dan 6 pompa) sesuai aturan. Analisis rotasi 7 hari membuktikan pemerataan beban kerja pompa dengan selisih maksimum hanya 1 siklus aktif per minggu. Integrasi IoT melalui platform Blynk berhasil menampilkan data sensor dan status pompa secara real-time dengan latensi rata-rata 1,8 detik. Disimpulkan bahwa sistem yang diusulkan terbukti unggul signifikan dibandingkan metode konvensional karena bersifat adaptif, antisipatif, proporsional, dan lebih andal.Kata kunci: Perancangan Sistem; Logika Fuzzy; Kontrol Pompa; Mitigasi Banjir; Internet of Things; Rotasi Pompa.
