Abstract

Analisis perbaikan jatuh tegangan dan reduksi rugi daya melalui uprating konduktor serta penyeimbangan beban pada sistem distribusi di PT. PLN ULP Tebing Tinggi. Sistem distribusi tenaga listrik sering menghadapi tantangan operasional signifikan pada jaringan tegangan rendah, terutama di wilayah dengan karakteristik panjang saluran besar, konduktor berpenampang terbatas, dan ketidakseimbangan beban antar fasa. Di ULP Tebing Tinggi, fenomena jatuh tegangan tinggi tercatat di ujung feeder jauh dari gardu utama, sementara rugi daya akibat aliran arus dan resistansi saluran menjadi beban biaya dan teknis bagi penyedia layanan. Penelitian ini menggunakan pendekatan kuantitatif berbasis analisis teknis yang menggabungkan pengukuran lapangan, perhitungan matematis, dan simulasi sistem tenaga menggunakan software ETAP. Pengukuran menunjukkan beban total gardu TT38 mencapai 91,69 kVA dengan ketidakseimbangan arus yang signifikan. Tegangan di ujung jaringan mengalami penurunan drastis menjadi 184 V dari tegangan pangkal 222-228 V, dengan jatuh tegangan sebesar 25,26% dan rugi daya 14,94 kW. Skenario uprating konduktor dengan mengganti kabel TIC 2×10 mm² menjadi TIC 3×70+1×50 mm² pada segmen 250 meter terakhir menunjukkan peningkatan signifikan. Hasil perhitungan dan simulasi ETAP konsisten menunjukkan penurunan jatuh tegangan dari 25,26% menjadi 3,61% (202,24 V) dan pengurangan rugi daya dari 14,94 kW menjadi 12,37 kW. Perbaikan ini berhasil membawa tegangan minimum ke dalam batas standar SPLN (198-231 V) yang sebelumnya tidak terpenuhi.

Abstract

Drying clothes is a process of daily activities. Drying clothes through the drying process is a traditional method that is still widely used in various regions. However, the process of drying traditional clothes is often a challenge for people or individuals who have limited space and time, especially if the drying is done at home while at the same time not at home. So it takes innovation of smart clothesline devices based on the Internet of Things (IoT) that can help optimize the drying process of clothes. In designing and manufacturing this automatic clothes drying system uses two sensors, namely water sensors and light sensors. Both of these sensors function as weather detectors. If it rains, the water sensor will respond by sending voltage to the circuit and then moving the servo motor to rotate to the right or left so as to make the clothesline enter a closed room. When the clothesline enters, Arduino will give a command to the GSM module SIM800L to give a notification in the form of an sms that the clothesline has been inserted. Similarly, with the light sensor, when the rain has stopped, the light sensor responds to sunlight so that it makes the servo motor move to remove the clothesline.

Abstract

A transformer is a vital component in the electrical power distribution system that functions to transfer energy from medium voltage to low voltage. The reliability of a transformer is highly influenced by the thermal condition of its insulation, which determines its service life. This study aims to predict the effective lifespan of a 1250 kVA distribution transformer at PT. Ultra Sumatra Dairy Farm uses the thermal aging method based on the IEEE C57.91-2011 standard. The data used includes nameplate information, daily load profiles, and average ambient temperature. Based on the measurements, the transformer operates at an average load of 422.7 kVA (33.8% of its rated capacity) and an ambient temperature of 23°C. The calculated results show a hottest-spot temperature of 49.55°C with an aging acceleration factor (FAA) of 0.000649. The daily Loss of Life (LOL) value of 0.00000865% indicates that thermal aging occurs very slowly. Based on the Equivalent Aging Factor (FEQA), the theoretical effective lifespan of the transformer reaches approximately 31,660 years. However, in practice, the actual lifespan of the transformer is estimated to range between 25–35 years due to non-thermal factors such as moisture, oil oxidation, and load fluctuations. These results indicate that the thermal condition of the transformer remains very safe and efficient for long-term operation.
