Angkasa Mart Store is currently experiencing a decline in sales for specific products, leading to the implementation of the Apriori Algorithm to create bundled offerings that combine less popular items with top-selling products, aiming to revitalize sales and promote the underperforming inventory. Following the CRISP-DM methodology, the study analyzes sales transaction data from June to July 2022, covering 65,892 purchased items, to extract ten critical association rules essential for devising bundled packages. The study's findings propose two strategies for package composition: first, the development of bundled packages comprising strongly related products, identified through comprehensive data analysis and positively received by the store; second, the introduction of 21 bundled packages consisting of products with a relatively weaker relationship, effectively expanding consumer choices and encouraging additional purchases within the store. By implementing the Apriori Algorithm and adhering to the CRISP-DM methodology, this study effectively formulates bundled product packages for Angkasa Mart Store, addressing the challenge of declining sales and contributing to an overall improvement in business performance and customer satisfaction.

Power transformer is an important component of the substation and has an important role in the electric power distribution system. During operation the power transformer can’t be isolated from distribution system when abnormal conditions or faults occur. A fault in the power transformer will have huge impact on the power transformer itself. The substation has an installed capacity of 60 MVA of power transformers, and during operation there is a possibility of relay failure, which may interrupt the power distribution process to the load. To avoid this failure, it is necessary to analyse the settings of Over Current Relay (OCR) and Ground Fault Relay (GFR) on the 60 MVA transformers. The analysis was carried out by simulating short circuit faults of the electrical system in the ETAP software application, and then configure the setting of the relay by referring to the magnitude of the short circuit current value for phase to phase and phase to ground. The results of this analysis are used as a reference to determine the OCR and GFR relay values in the power transformer. The results obtained show that the recommended value for OCR setting on 150 kV power transformers is 0.92 second while for GFR is 0.96 second, and for the 20 KVA power transformers the OCR and GFR setting values are 0.40 and 0.20 seconds respectively. Comparison based on the results of the setup data and the analysis data has carried out, there is difference in the working time of the relay, with a difference of 5%, where the value of the analysis results is not much different from the conditions in the field.

Load shedding is a protection scheme to maintain the stability of the electric power system. When there is an imbalance between the power generated and the load power, load shedding will release the load to restore power balance. This research aims to design and analyze the load shedding system at Private Company to see whether it is running well and meets the PRC-006-5 standard regarding the frequency operating limit, which must be in the range of 49.42 Hz to 50.58 Hz. The method that will be used in this research is to carry out testing with software and then analyze the power and frequency response due to the generator being removed from the system. The testing mechanism that will be carried out is to simulate the effect of a lack of power for the load supply on the load shedding system. From the research results, it is known that the existing load shedding scheme needs to be evaluated. Evaluation is carried out on steps 1 and 2, so that the load shedding limit for step 1 becomes 49.5 Hz and the pickup time for step 4 becomes 400 ms.

In area mining are quite extreme, where the level of safety from high temperatures and toxic gases which are explosive as well as well flow pressure is also high and can damage production equipment. Therefore, it is very necessary to install reliable electrical power, starting from analyzing the selection of cable types that used, voltage drop, power losses and transformer selection. The problems mentioned previously, this research carried out an analysis of improvements to voltage drops and power losses that occurred in the ESP motor installation system. The method used is to replace the type of cable used in three scenarios with three different types of cable. The installation system data obtained from this company was then processed using software which was then validated with theoretical calculation results. The result of voltage drops and power losses in ESP cables according to standards using scenario 3, replacing AWG 2/0 type with a voltage rating of 5 kV, diameter of 11.709 mm and has a KHA of up to 210 A. The voltage drop value after repairs are carried out based on theoretical calculation results has an average percentage index value of 4.5% and power losses of 4.6%. This shows that in the condition after repairs, both the results of simulation calculations and theoretical values have met the IEEE std 141-1993 standard which states that the value of voltage drop and power losses in industrial plan distribution systems must be below 5%.

Renewable energy has an important role today, one of which is hydroelectric power plants which use water as the main resource. The operation of a hydroelectric power plant generally aims to maximize the water discharge available in the reservoir in order to obtain maximum energy generation. The main driver of hydropower development is the hydraulic turbines. It's a mechanical device that turns the potential energy of water into electrical energy. So researchers are interested in conducting research with the title analysis of the effectiveness of electrical energy based on reservoir conditions. The method used in this research is daily data collection in the form of reservoir elevation level data, outflow, and data on the electrical power generated by the generator. After that, calculate the water volume, hydraulic power, turbine mechanical power along with turbine efficiency, and the efficiency of the generator. Then analyze the values of hydraulic power, turbine mechanical power, electrical power based on water discharge over time. As well as analyzing the efficiency of the generator based on the electrical power that can be generated over a period of one year. Based on research, it is known that an increase in powerplant efficiency occurs after draining the reservoir with a value range of 70% - 72%, because mud deposits accumulate in the reservoir resulting in the reservoir water volume capacity not being optimal.

Based on the results of the research conducted, it can be concluded that the 5G network at Airport shows excellent performance in supporting the use of VoIP applications such as Instagram, WhatsApp, and Zoom. This is indicated by a consistent category 4 index on all measured parameters, namely throughput, packet loss, delay, and jitter. In terms of throughput, although there are variations between the three apps, all values are still sufficient to support voice and video calls with good quality. In fact, the lower throughput value on the Zoom app does not mean that the video call quality is poor, especially for one-on-one calls or with few participants. Furthermore, the absence of packet loss in all three applications indicates excellent connection stability. This is an important indicator showing that all the data sent and received by the apps made it to their destination without being lost midway, which is essential for ensuring clear voice and video quality. Meanwhile, very low delay and jitter indicate that data transmission is fast and consistent. This is especially important for real-time communications such as video calls, where delays or variations in the arrival time of data packets can disrupt call quality. Overall, the results of this study show that the 5G network at Airport is capable of supporting the use of VoIP applications with good quality. This is an important finding, given the importance of VoIP in everyday life, both for personal and professional communication. Therefore, this research hopes to make an important contribution in understanding and maximizing the potential of 5G network in supporting VoIP communication at Airport.

In my previous work published in an acknowledged publication, titled "Factory test of a TP-100 Lithium Ion Vision Battery System for possible Implementation in Soweto, Johannesburg, South Africa," According to the findings from the study report, the TP-100 Vision Lithium-Ion battery system was found to be suitable for implementing a wind turbine system in Soweto. Furthermore, the study's findings indicated that Lithium-Ion batteries were the optimal choice for storing energy in wind turbines. These batteries provided significant total cost of ownership (TCO) reductions over a 10-year period, without the inconvenience and expenses associated with replacing lead-acid batteries. This research paper aims to validate the precision of parameters obtained from the integration of a 160 kVA Vetiv Three Phase UPS to a TP-100 Vision Lithium Ion Battery system in contrast to those obtained from the Battery Monitoring System (BMS) while using Tool BMS Version 1.3 Software. The results validation was evident as the parameters acquired from the UPS and Battery system were found to be accurate when compared to those observed through the BMS tool. Finally, utilizing the Smart Cloud Management System (SCMS), validity was shown by the ability to remotely monitor the operation of both the UPS and the Li-ion Battery system.

One of the main areas of focus for power electronics development nowadays is interleaved parallel magnetic integration technology. On the basis of introducing the staggered parallel connection technology of internal combustion engines and power systems, the staggered parallel connection magnetic integration technology of power electronics is introduced. First, the interleaved parallel magnetic integration technology of various non-isolated and isolated DC-DC converters and their latest research results and applications are introduced; then, the three interleaved parallel technologies of internal combustion engines, power systems, and power electronics are compared; and finally, the current situation is pointed out. In China, research on interleaved parallel magnetic integration technology is not lagging behind internationally, but there is relatively little research on interleaved parallel magnetic integration technology for isolated DC-DC converters. It is recommended that research in this area be strengthened in the future. Looking to the future, the staggered parallel magnetic integration technology of power electronics will develop even more like the staggered parallel technology of internal combustion engines and power systems and make significant contributions to the development of industry and the national economy. Through this exploration, the paper aims to provide a critical analysis of the current state of research, offering valuable insights for engineers, researchers, and industry professionals involved in power electronics and converter design.
