Abstract

The primary focus of this research was to create a Smart Count of Vehicle Loading Prototype for ships, with an emphasis on monitoring and tallying vehicles boarding and disembarking from ships based on their weight. Microcontrollers, such as the ESP32, were utilized for the counting process and to determine if the ship's cargo weight exceeded its maximum capacity. The main objective was to prevent overloading on ships, which could lead to accidents during voyages or while vehicles were being loaded onto the ship. To achieve this goal, weight and distance sensors were installed on the ship and controlled by the microcontroller, allowing for accurate monitoring of the quantity and categories of vehicles being loaded. After designing and testing this prototype device, it has become a new technological innovation that makes monitoring the weight and quantity of cargo on ships easier and more efficient. This is supported by the fact that each sensor's readings can work well with an average error rate below 2%. Additionally, the maximum communication range between the Blynk IoT application and the ship system can reach up to 20 meters.

Abstract

This study aims to improve students' understanding and skills in the makeup and costume of the Gambyong Pareanom dance through the application of the modelling method assisted by audio-visual media. The research subjects were 35 students of class X SP 5 at SMK Negeri 8 Surakarta for the 2024/2025 academic year. The research was conducted in three cycles, each consisting of planning, action, observation, and reflection stages. The learning method involved the use of videos, live demonstrations, group discussions, and independent practice. The results showed significant improvement in each cycle. In the pre-action stage, only 40% of students felt helped by the method and 68% lacked self-confidence. In Cycle I, 55% felt helped and 60% began to show better understanding. In Cycle II, with more interactive media, 72% of students felt helped and 68% reached the minimum passing grade (KKM). In Cycle III, 88% of students found the method very effective, 85% achieved the KKM, and 83% showed improved confidence. These findings prove that the modelling method using audio-visual media is effective in enhancing conceptual understanding, technical skills, and student confidence. The study recommends broader application of this method in vocational school skill-based learning to create a more engaging, contextual, and relevant learning experience aligned with workforce demands and cultural preservation.

Abstract

This study aims to analyze the effect of Good Corporate Governance mechanisms on financial performance in infrastructure sector companies listed on the Indonesia Stock Exchange (IDX) for the 2019-2023 period. The GCG mechanism in question includes institutional ownership, board of directors, board of commissioners, and audit committee. The company's financial performance is measured using the Return on Assets (ROA) indicator. This research approach uses quantitative methods with panel data regression analysis techniques. The population in this study consisted of all infrastructure companies listed on the IDX during the observation period, and purposive sampling technique was used to determine the sample in accordance with certain criteria. The test results show that partially, only the audit committee variable has a positive and significant effect on financial performance. Meanwhile, the variables of institutional ownership, board of directors, and board of commissioners did not show a significant effect. These findings reinforce the importance of the audit committee's role in overseeing and ensuring effective governance to support the improvement of the company's financial performance.

Abstract

There are several common problems in the beauty industry related to these variables. In social media marketing, the level of competition is very high, with many brands vying for consumer attention. Small brands may struggle to stand out among the big brands. Products that don't suit a consumer's skin type or concerns can lead to negative experiences and damage a brand's reputation. Consumers' experiences influence their reviews and recommendations, which can have a positive or negative impact on the company (Susanti & Gunanto, 2022) .This research aims to identify the influence of social media marketing, product quality, and price perceptions on purchasing decisions for Somethingnc skincare. The sample was determined using a purposive sampling technique with a total of 100 respondents. The validity and reliability of the questionnaire were tested using the SPSS 23 tool. The results of this research show that social media marketing, product quality, and price perceptions have a significant positive influence on purchasing decisions.

Abstract

This study explores the development of low-carbon concrete by integrating industrial waste materials and CO₂-absorbing minerals to reduce carbon emissions in the construction industry. The research investigates various mix ratios involving fly ash, slag, and CO₂-absorbing minerals, aiming to optimize both performance and sustainability. Experimental methods included compressive strength testing, carbon emission measurement, and durability evaluation. The results indicate that low-carbon concrete formulations achieve up to 45% reduction in carbon emissions compared to conventional concrete, which uses Portland cement. Despite a slight decrease in compressive strength, the optimal mix reached 34 MPa, which is sufficient for structural applications. Durability testing revealed that concrete with CO₂-absorbing minerals showed improved long-term performance compared to other formulations. The findings highlight the potential of using industrial waste materials and carbon capture technologies to create more environmentally sustainable concrete while maintaining necessary structural properties. This study contributes to the growing demand for eco-friendly construction materials and supports the implementation of low-carbon concrete in large-scale industrial applications. Further optimization of mix ratios and long-term performance studies are recommended for broader adoption in the construction industry.
