Penyaluran tenaga listrik jaringan tegangan menengah melalui saluran kabel tanah merupakan konstruksi penyaluran tenaga listrik yang aman dan handal. Namun saat terjadi gangguan, maka akan sulit untuk mengetahui dan mendeteksi lokasi titik gangguan. Dengan dilakukannya assessment kabel yaitu pengujian partial discharge secara off-line maka akan memudahkan untuk mengetahui kondisi kabel yang berada di dalam tanah sehingga nantinya dapat diketahui apakah kabel tersebut layak atau tidak untuk dioperasikan. Pengujian ini dilakukan pada segmen JTU 3- KC 318, penyulang pipi dimana langkah ini merupakan tindakan preventif untuk meningkatkan kehandalan penyaluran tenaga listrik dan mengurangi jumlah gangguan pada jaringan. Peluahan sebagaian (partial discharge) jika dibiarkan secara terus menerus akan membahayakan kesehatan kabel yang nantinya akan berpengaruh terhadap nilai isolasi dan besarnya sehingga dapat menyebabkan breakdown. Partial Discharge muncul karena adanya kerusakan pada insulasi kabel. Partial Discharge merupakan peluahan listrik secara sebagaian dari isolasi diantara konduktor baik yang terjadi di permukaan atau isolasi kabel. Hasil pengujian partial discharge JTU 3 – KC 318 diperoleh PDIV < Uo, PDEV > Uo dan besar muatan (Y) >1000 pC maka berdasarkan health index PT. PLN (Persero) matriks pejumlahan sumbu X dan sumbu Y yaitu X + Y = 2+3 = 5. Status kabel adalah buruk dengan poin 5 serta estimasi untuk pengujian ulang kembali adalah 6 bulan. Diharapkan dengan dilakukannya pengujian ini dapat mengurangi jumlah gangguan pada kabel SKTM dan menjadi langkah tindakan preventif yang baik untuk mencegah kondisi event breakdown.

This research aims to design and test a genset fuel conversion system from gasoline to HHO gas (brown gas) as a more environmentally friendly alternative. Conventional fossil-fueled generators face challenges in theform of limited resources and the impact of environmental pollution. In this study, HHO gas is produced through a water electrolysis process using an HHO generator that separates water molecules into hydrogen and oxygen using electric current. The test results show that increasing the voltage from 2.58 V to 5.12 V significantly increases the volume of gas produced. At a voltage of 2.58 V, the gas volume reached 110 ml, and increased to 750 ml at a voltage of 4.72 V. The generator set was successfully operated for 1 minute 15 seconds with HHO gas using a separate battery power source. These results demonstrate the potential of HHO gas as an efficient alternative fuel for generator sets. This study recommends further testing with voltage and current variations to find the optimal configuration, as well as the use of a larger power source to increase the efficiency of HHO gas electrolysis.

This study examines the role of Artificial Intelligence (AI) in marketing strategy through a Systematic Literature Review (SLR) approach. AI has shown a transformative impact by outperforming traditional methods, especially in optimizing big data-based marketing strategies. With the ability to analyze consumer behavior in depth, AI enables businesses to personalize marketing efforts and improve user experiences more efficiently and responsively. However, challenges such as data privacy, high initial investment, and reliance on data quality remain major concerns that must be addressed. This study also evaluates the effectiveness of using AI across marketing channels, which shows significant differences in their impact on business strategy. In addition, the integration of AI-based fitness equipment is considered to have a major contribution in increasing consumer satisfaction while driving online business growth. The results of this study provide valuable insights into the effective implementation of AI, as well as highlight the importance of maintaining data security and implementing AI strategically to provide optimal benefits for consumers and business development.

This study aims to examine the impact of a 6-phase design using an asymmetrical dual
3-phase design on the torque and speed of an induction motor, where the newly designed motor still uses a 3-phase power source. The research compares the performance of a conventional 3-phase induction motor with that of an asymmetrical 6-phase induction motor design, focusing on torque and speed. This motor is only designed in terms of its windings, so the motor's position remains unchanged. The 3-phase system applied to the 6-phase induction motor design ensures that the 6-phase motor operates within a 3-phase system. The study also explores performance improvements, particularly in torque and speed, by redesigning the windings of a 3-phase induction motor into an asymmetrical 6-phase motor.
The induction motor used in this research has the following specifications: 3-phase, 2 A, 1390 RPM, 50Hz, 0.75 kW, and 380Y. The study aims to understand the effects of the asymmetrical 6-phase induction motor design, particularly regarding torque and speed. The results show that the torque and speed of the two motors differ due to the asymmetrical 6-phase winding design. In a conventional 3-phase induction motor, the winding coil layer distance is 120°, whereas, in the asymmetrical 6-phase induction motor, the distance between the first and second layers is 30°. Based on this analysis, the asymmetrical 6-phase induction motor design demonstrates better performance compared to the conventional 3-phase induction motor.
