Starting from the development of medical technology that is increasingly sophisticated and rapidly growing,researchers conduct medical research, namely about patient infusion handling services. In handling patient infusion, currently it is still manual which is carried out by nurses / medical personnel. Infusion handling services for patients still have shortcomings, namely the process of monitoring and replacing infusion fluids which are often late. If the problem is not treated quickly, it can lead to problems, namely the presence of air embolism in the blood vessels (the entry of foreign objects into the blood vessels, for example air). From that problem, the researchers made a new innovation in medical technology in handling infusions automatically and based on IoT. In this study, the smart online infusion device that has been made has good features and is very effective in handling infusions. This device has 3 main functions, namely: it can monitor the remaining infusion, it can change the infusion fluid automatically and it can indicate a blocked patient's infusion. This device already has a method for processing data with fuzzy logic. Media monitoring has been supported by a website that can be controlled remotely and in real time. Tests have been carried out and the effectiveness of the system is found to have an error rate of 0.2% - 0.7% and has an accuracy of 98%. Thus this tool can be used in terms of handling patient infusion automatically.

Distribution substations are one of the important assets managed by the State Electricity Company (PLN), especially distribution transformers to distribute electric power to consumers. The MOADK006 Distribution Substation is located in Wakarleli Village, Moa District, Southwest Maluku Regency, Maluku Province with a transformer capacity of 100 kVA which is supplied by the Inner City Feeder of the PLN Moa electricity system. The transformer experiences a load condition exceeding 80% of its capacity. To overcome the problem of overloading at the MOADK006 distribution substation, which reached 93.72% of the 100 kVA capacity, it has exceeded the standards set by PLN ED Decree No.0017.E/DIR/2014. As a solution, an insert transformer with a capacity of 100 kVA was added. After adding the insert transformer, the MOADK006 distribution substation load was reduced to 45.02%, while the insert transformer bore a load of 48.81%. With this load distribution, the two distribution substations are in good loading condition, namely less than 60%, in accordance with the guidelines of PLN ED Decree No.0017.E/DIR/2014. It is estimated that the MOADK006 distribution substation can last up to 8 years. The voltage measurement at the end of the network after adding the insert transformer also experienced improvements, where the results of the Drop Voltage value at the end of the network before and after adding the insert transformer were 8.88% to 2.70% for the R phase, 7.59% to 3.16% for the S phase, and 7.55% to 2.25% for the T phase. Thus, the addition of the insert transformer proved to be effective in reducing the load on the distribution substation. MOADK006 and improves the voltage value at the end of the network, so that it meets applicable operational standards.

Gangguan dalam sistem tenaga listrik dapat terjadi kapan saja akibat kegagalan perangkat atau komponen yang tidak berfungsi sesuai dengan kinerjanya, sehingga menimbulkan risiko terganggunya kontinuitas penyaluran tenaga listrik dan menurunkan keandalan sistem secara keseluruhan. Salah satu upaya pengendalian gangguan adalah melalui koordinasi proteksi dengan pola noncascade antara relay OCR sisi incoming 20 kV dan relay penyulang 20 kV pada trafo. Pada tanggal 8 Februari 2023, hasil implementasi pola proteksi Non-Cascade pada Bay Trafo 3 GI Cengkareng mengalami anomali yang menyebabkan trip PMT Incoming dan penyulang kosmetik. Gangguan ini mengakibatkan pemadaman beban sebesar 29 MW selama 16 menit, yang berdampak pada berkurangnya keandalan penyaluran listrik serta menimbulkan kerugian ekonomi signifikan bagi PLN dan pelanggan industri. Analisis menunjukkan kesalahan penyetelan fungsi logic relay OCR pada penyulang 20 kV. Ditemukan logic fungsi CBF dan kontak output Buspro pada relay penyulang kosmetik belum aktif yang menyebabkan OCR penyulang tidak mengirim sinyal blok dan mentripkan PMT Incoming. Dilakukan breakdown maintenance dengan resetting logic pada rele penyulang kosmetik kemudian dilakukan pengujian waktu kerja relay OCR (hasil sesuai IEC 60255) dan uji fungsi pada logic (hasil sesuai kesepakatan UITJBB dan UID th 2022). Disimpulkan kinerja relay sesuai dengan pola proteksi non cascade dan sistem dapat dioperasikan kembali

n the working area of PT PLN (Persero) UP3 Wamena, the electricity distribution system still uses a radial configuration which has weaknesses in service continuity and feeder reliability on the 20 kV Medium Voltage Network (JTM). Geographical challenges and extreme climate in the Papua Mountains Province also exacerbate this condition. This study aims to analyze the reliability level of the Kaonak, Nayak, Baliem, Byak, Napua, and Interconnection Feeders using the SAIDI, SAIFI, CAIDI, and MAIFI index calculations according to the SPLN: 68-2 Year 1986 and IEEE 1366-2012 standards. The calculation results show that most feeders in 2023 and some in 2024 have not met the SAIDI and SAIFI standards according to SPLN and IEEE despite significant improvements in 2024. Meanwhile, the CAIDI index of all feeders is still within reasonable limits according to both standards. The MAIFI index cannot be calculated due to limited recloser equipment performance. Frequency quality still meets standards (50.2-50.3 Hz), but the total harmonic distortion (THD) of the feeders exceeds the limit with a value of ≥ 5%. The main network reliability issues are caused by difficult topography, limited access, and natural conditions that complicate disturbance management. Recommendations to improve network reliability include maintenance and optimization of primary distribution materials.

Load imbalance in three-phase distribution transformers can increase neutral current and power losses, thereby reducing the efficiency and reliability of electric power distribution systems. This study aims to analyze the level of load imbalance, power losses caused by neutral current, and the effectiveness of manual load balancing using the two-time-point method, namely peak load time (PLT) and off-peak load time (OPLT). The research was conducted on the PNIAI007 distribution transformer at PT PLN (Persero) ULP Enarotali using a quantitative descriptive approach with a case study design. Data were obtained through measurements of phase currents and neutral current, which were then analyzed to compare conditions before and after load balancing.The results show that the load imbalance level was significantly reduced from more than 29% to 2.47% during daytime operation and 1.21% during nighttime operation. The neutral current decreased from 37.81 A to 14.58 A during the daytime and from 51.76 A to 19.83 A at night. In addition, power losses due to neutral current were reduced by more than 85%. These results indicate that the two-time-point load balancing method is effective in improving the efficiency and operational reliability of distribution transformers.

Generator step-up transformator merupakan peralatan vital dalam sistem pembangkitan tenaga listrik karena berfungsi menaikkan tegangan keluaran generator ke level transmisi. Keandalan transformator ini sangat menentukan kontinuitas penyaluran daya, sehingga kegagalan operasi dapat menyebabkan gangguan sistem yang signifikan, penghentian operasi pembangkit, serta kerugian ekonomi yang besar akibat tingginya biaya perbaikan dan lamanya waktu pemulihan. Salah satu faktor utama yang mempengaruhi umur operasi transformator adalah kualitas sistem isolasi, khususnya minyak isolasi yang berperan sebagai media isolasi listrik sekaligus pendingin. Selama beroperasi, minyak isolasi dan isolasi kertas dapat mengalami degradasi akibat beban termal dan elektris, yang ditandai dengan terbentuknya gas-gas terlarut sebagai indikator gangguan internal transformator.Dissolved Gas Analysis (DGA) merupakan metode diagnosis kondisi transformator yang telah diakui secara internasional karena mampu mengidentifikasi jenis gangguan berdasarkan pola dan konsentrasi gas terlarut. Namun, penerapan DGA konvensional yang dilakukan secara periodik memiliki keterbatasan dalam mendeteksi gangguan. Oleh karena itu, penelitian ini bertujuan untuk mengkaji implementasi dan analisis data DGA Online Monitoring dalam mendukung deteksi dini gangguan internal serta prediksi keandalan generator step-up transformator pada sistem pembangkitan listrik di Jawa Barat. Metode penelitian dilakukan melalui analisis data gas utama hasil pemantauan DGA online secara real-time, yang meliputi konsentrasi gas – gas seperti asetilena (C₂H₂), etilena (C₂H₄), dan karbon monoksida (CO). Hasil penelitian diharapkan mampu menunjukkan efektivitas sistem DGA online dalam meningkatkan ketepatan waktu tindakan pemeliharaan, mengurangi risiko kegagalan transformator, dan meningkatkan keandalan sistem pembangkitan secara keseluruhan.Kata kunci: generator step-up transformator, minyak isolasi, dissolved gas analysis, DGA online monitoring, keandalan transformator.
