Abstract

In the era of digital transformation, credit cards have become an essential component of modern financial life, where users’ understanding of card features significantly influences their financial decisions. Despite the wide use of advertising in the financial sector, limited studies have explored how credit card users in emerging markets respond to such campaigns. Addressing this gap, this study analyzes advertisement awareness patterns among credit card users in Indonesia using the K-Means Clustering algorithm on a dataset collected from August 2023 to March 2024. The study aims to examine levels of advertisement awareness, segment users based on their responses, and assess the implications of these segments for marketing strategies. The methodology follows the Knowledge Discovery in Database (KDD) process: data selection, preprocessing, transformation, clustering with K-Means, and evaluation using the Silhouette Score. Results reveal three distinct user clusters: (1) highly aware users in large cities with high exposure; (2) moderately aware users from mid-tier cities; and (3) low-awareness users despite high exposure, often from older age groups and lower SES backgrounds. The clustering yielded Silhouette Scores above 0.60, validating segmentation quality. The novelty lies in applying machine learning to segment awareness levels using a multi-city real-world dataset. The findings offer practical value for credit card providers to enhance targeted campaigns, improve user engagement, and allocate marketing resources more effectively across demographic segments.

Abstract

Damage to the surface of solar panels, such as cracks, scratches, and stains, can reduce the energy efficiency produced. The surface of solar panels often experiences various types of damage such as cracks, scratches, stains, or being in good condition, which can affect energy absorption efficiency. The data used in this study consists of 4000 images covering various categories of surface conditions. The method used in this research is the Texture Feature Extraction Method with statistical indicators, namely Mean, Variance, Standard Deviation, Skewness, Kurtosis, and Entropy, to identify existing damage patterns. These features are then analyzed and classified to determine the type of damage on the panel surface. The feature extraction process generates data representations that depict the texture patterns of each surface condition category. This research aims to identify damage on the surface of solar panels using texture-based feature extraction techniques to support the efficient maintenance of solar panels.

Abstract

The rising demand for electricity in Manokwari, the capital of West Papua Province, Indonesia, necessitates urgent improvements to the existing 20 kV distribution system, which struggles to maintain voltage compliance with grid code standards and meet projected future loads. This study examines two operational alternatives: (1) the construction of a 150 kV transmission line from the Gas Engine Power Plant (PLTMG) substation to the Prafi Substation, and (2) the development of an express feeder from the same source. Using DigSILENT PowerFactory software, operational feasibility is assessed through voltage regulation, transformer and line loading analysis, and N-1 contingency compliance. The investigation includes power flow simulations, short-circuit fault analysis, and system stability evaluations, focusing on rotor angle, voltage, and frequency stability. Findings provide technical recommendations to enhance the reliability, resilience, and sustainability of Manokwari’s power infrastructure, supporting strategic planning and operational optimization.

Abstract

Choosing better organic solvents and providing appropriate mixing ratios for thinner in the automotive paint industry. The research objects were true solvents, ethyl acetate, butyl acetate, and acetone; alcohol cosolvents are isopropyl alcohol, isobutyl alcohol; and non-solvents are n-heptane, propylene glycol, and mineral spirits. Adhesion and coating thickness by spray paint and turbidity of thinner were performed. The thinner dissolving rate was evaluated by immersing coated galvalume plates (50 mm × 50 mm × 0.4 mm) into thinner and recording the time required to dissolve the paint. Thinner testing was conducted using a spray method at 17 cm distance and 90° angle, with coating thickness measured by coating thickness gauge and adhesion evaluated using the ASTM D3359 tape test. The best Performance was observed in the 5:3:3 composition (EA:IPA:MS), which achieved a 5B adhesion rating and a coating thickness of 60.7 µm. This ratio also had the lowest turbidity value (0.11 ± 0.02 NTU). Based on the capability plot analysis, this composition demonstrated high process capability (Cp = 3.06; Cpk = 2.52), confirming its suitability as the optimal formulation for automotive thinner applications.

Abstract

Currently, the distribution network installed in the business area of Manado City still uses medium-voltage overhead lines (SUTM), while an underground cable system (SKTM) has been planned for implementation. To ensure the reliability of the planned underground distribution network, the selection of protection devices is crucial. In addition, there is still a lack of OCR analysis for underground distribution system protection in Manado City. Therefore, this study aims to obtain the settings for the overcurrent relay (OCR) on the underground cable conductors on the low voltage side. The data needed for this study was obtained through direct field surveys and interviews with relevant parties to gather additional information regarding the standards for underground cable construction. Considering the potential increase in load in the future, the calculation of the OCR protective settings was performed by calculating the cross-sectional area of the medium voltage conductors and the current-carrying capacity of the low voltage conductors. As a result, the setting value for the OCR was determined to be 5 Amperes with a Time Multiplier Setting (TMS) of 0.004.

Abstract

PT XYZ's Component Exchange (COMEX) Department has 8 Quality Assurance Processes, one of which is performance test (QA6). The performance test is conducted to evaluate the condition of overhauled components. From January to February 2024, the COMEX Department experienced issues with electrical components in the Power Train area, specifically the Electronic Control Modulating Valve (ECMV) solenoid, torque flow speed sensor, and rear brake speed sensor. Currently, the functional inspection tool for the solenoid only uses an Arduino as a power supply and an impact wrench as a substitute for the gear shaft to inspect the torque flow speed sensor and rear brake speed sensor. The results from these inspections are inaccurate, leading to rework on the transmission components and the brake final drive of the HD785-7. The 8-step method was used to address these issues. This method includes Determining Themes, Current Condition Analysis, Target Setting, Root Cause Analysis, Improvement Plan, Improvement Implementation, Result Evaluation, Standardization and Improvement Plan. Improvements included creating an electrical performance test tool, developing work instructions for using the tool, and establishing a reusable parts standard. The tool successfully reduced the rework of electrical parts, achieving a 100% reduction in rework from January-February 2024 to April-June 2024.

Abstract

Seaweed is a plant that is adaptable and is used in a variety of industries, such as food, cosmetics, and medication. However, the current seaweed processing technique, which entails sun drying, is still highly traditional and requires a significant amount of time. To speed up draining and drying seaweed, we developed a hybrid energy-powered seaweed draining and drying. The tool capacity of this design is 50 kg, and it applies the Pahl and Beitz method. The selected design is variant 3 with the highest weight value of 7.74. The design outcomes produce the following tool specifications the drive is equipped with a diesel motor with a power of 3.5 Hp, 2.6 kW, and 3600 rpm, as well as three solar panels of the MCS1100 model, each with a capacity of 100 Wp. The container dimensions of 382 mm diameter and 500 mm height. The seaweed is to be dried at a rate of 29,3 kg/m2 per hour. The galvanized steel frame yielded a maximum working stress value of 126.223 N/mm2, which is lower than the material's yield strength value of 203.943 N/mm2. On the shaft made of S45C8 steel, the maximum working stress value after applying the load is 66.83 N/mm2, which is also less than the material's yield strength value of 350 N/mm2. This indicates that the stand and shaft design is safe, as the simulation process's maximum stress value does not surpass the material's yield strength value.

Abstract

Variations in task performance under different cognitive demands are often interpreted as indicating mental workload. Prior research has identified a link between personality and task performance. This study investigates whether personality traits influence performance under varying levels of mental workload in working memory tasks. Personality traits were assessed using the Eysenck Personality Inventory. Participants completed n-back tasks at three levels of difficulty to induce different levels of mental workload. The findings reveal significant differences in response times between extroverts and introverts across all task difficulties (p < 0.05), with introverts responding more quickly. A significant difference between neurotic and stable individuals emerged only at the medium difficulty level (p < 0.05), with stable individuals performing faster. Additionally, response times varied significantly across personality quadrants, with introvert-neurotic individuals showing faster responses at both low and high difficulty levels.
