Abstract

West Pasaman Regency has varied topography that influences land surface temperature (LST) distribution. This study analyzes LST patterns and compares estimates from Landsat 8 and Landsat 9 imagery in 2024 using a quantitative remote sensing approach via Google Earth Engine. LST was derived from thermal infrared bands, while vegetation influence was assessed using NDVI and Pearson correlation. Results show uneven temperature distribution affected by topography, vegetation cover, and land use. Landsat 9 produced slightly higher average temperatures (±30–38 °C) than Landsat 8 (±26–32 °C). A strong correlation was found between both datasets, with a negative correlation between NDVI and LST, indicating that denser vegetation corresponds to lower surface temperatures. Both satellites are suitable for LST analysis, with Landsat 9 showing higher sensitivity.

Abstract

Planning villa development in complex topographic areas requires accurate and detailed terrain information to ensure safety, construction efficiency, and environmental sustainability. This study aims to utilize LiDAR data to generate a Digital Terrain Model (DTM) and conduct slope analysis to support villa development planning in Budo Village, Wori District, North Minahasa Regency. The research employed a quantitative applied approach using LiDAR point cloud data processed through classification, filtering, and interpolation to produce a DTM, followed by slope analysis using GIS. The results show that the study area has elevation variations between ±73 and ±173 meters above sea level with a vertical RMSE accuracy of 0.487 meters, classified as very good. Slope classification indicates that flat (0–8%) and gentle (8–15%) areas dominate the central region and are highly suitable for villa development due to low geotechnical risk and minimal earthwork requirements.

Abstract

The research was conducted to analyze the influence of social media marketing on purchase decisions of Skintific products, as well as the role of brand awareness as a moderating variable among Skintific consumers in Banda Aceh. This study employed a quantitative method, where primary data were obtained through questionnaires distributed to 96 respondents selected using purposive sampling based on Cochran's formula. Data analysis was performed using Moderated Regression Analysis (MRA). The results indicated that social media marketing has a positive and significant influence on purchase decisions of Skintific products. However, brand awareness was not found to moderate the effect of social media marketing on purchase decisions. Nevertheless, brand awareness significantly acts as a predictor in enhancing the purchase decisions of Skintific products. The implications of this study emphasize the importance of social media marketing strategies in increasing purchase decisions, as well as the need for companies to strengthen brand awareness as a factor that can drive consumers in making purchasing decisions.

Abstract

This study aims to analyze the causes of malfunction in the auxiliary fuel pump component and to carry out troubleshooting and replacement procedures on a Cessna 172S aircraft (PK-BYL) owned by the Indonesian Aviation Academy Banyuwangi. The auxiliary fuel pump is a critical part of the fuel system that supports engine start-up, emergency operation, and the engine-driven fuel pump. A qualitative descriptive method was used through direct observation during On-the-Job Training (OJT) at the academy hangar. The results show that the malfunction was indicated by the absence of pump sound during priming, a stagnant fuel flow (FFLOW GPH) on the Garmin Display Unit, and voltage readings below the 24V DC standard. The average measured voltage was 12.197 volts, indicating the component was unserviceable. The troubleshooting process involved replacing the auxiliary fuel pump according to the Aircraft Maintenance Manual. After replacement and functional testing, the system returned to normal operation, and the aircraft was declared serviceable and ready for flight.

Abstract

The construction sector stands as one of the most resource-intensive human activities, with reinforced concrete accounting for a disproportionately large share of material consumption and carbon emissions in built environments worldwide. This paper examines how sustainability management principles grounded in green construction can be normatively embedded in the design and assessment of reinforced concrete floor slabs and beams. Drawing on a qualitative review of academic and technical literature, the study investigates the structural, material, and managerial dimensions through which green construction principles can be operationalized in the engineering practice of reinforced concrete design. Key areas addressed include material efficiency in slab and beam sizing, the use of supplementary cementitious materials, life cycle perspective in structural decision-making, reinforcement optimization, and the coordination between structural design and construction management. The study affirms that structural reliability and environmental responsibility are not competing objectives, but can be achieved simultaneously through informed, systematic, and principled design decisions.

Abstract

The study addresses anomalies in insulator leakage current caused by corrosion, cracking, weather exposure, and salt spray pollution in coastal transmission lines. These issues were identified during the annual maintenance of the Sanur–Pesanggaran 150 kV transmission line at Tower 1 Pole 53. Additional contributing factors include the insulators’ service life of 25–30 years and inadequate cleaning maintenance. Such conditions increase the risk of flashover and insulator failure, reducing transmission system reliability. This research evaluates the feasibility of glass insulators equipped with a zinc sleeve layer to improve corrosion resistance, reduce leakage current, and extend service life in coastal environments. The methodology involved determining the insulator model, analyzing PLN inspection reports (2023), collecting installed insulator data, measuring leakage current, and assessing post-test conditions. The study examined 83 towers along the Pesanggaran–Sanur 1 transmission line. Results indicate that the insulator at Pole 53 failed to meet the required standard, whereas zinc sleeve-coated insulators on other poles complied with IEC 60815:2021 based on leakage current test results.

Abstract

This study aims to analyze soil characteristics, soil bearing capacity, and foundation recommendations for the construction project of Dr. Radjiman Wediodiningrat Mental Hospital in Lawang–Malang using the Cone Penetration Test (CPT) method. The research method used is a quantitative approach with field research through field testing at observation points S1, S2, and S3. The data obtained were analyzed based on the Cone Resistance (qc), Friction Ratio (Rf), cone pressure (Cn), and the amount of adhesive resistance (JHP) to determine the bearing capacity of the foundation. The results showed that the soil layer at a depth of 0–2 meters was dominated by soft soil in the form of clay and silt, while at a depth of 4–7 meters a layer of dense to very dense sand was found with a qc value ranging from 100–150 kg/cm² and an Rf value of less than 2%. These conditions indicate that the deep soil layer has good bearing capacity for deep foundations.

Abstract

Research on sensor networks in oil palm plantations tests small prototypes over short periods and rarely addresses security, while research on agricultural sensor network security is simulated on generic topologies that ignore canopy attenuation, so the two streams have developed separately. This article presents an integrated research design for analyzing wireless sensor network performance and security in oil palm land monitoring. As a research design article, its purpose is to formulate a replicable methodological framework rather than report measurements. The design combines NS-3 simulation across 36 treatment combinations replicated thirty times, yielding 1,080 runs, with twelve months of field testing on two canopy conditions using fifteen LoRa SX1278 nodes per block. Four security configurations are compared against four attack scenarios, with operational definitions specified for five performance and three security indicators. Four hypotheses are formulated, of which the interaction between topology and security configuration is the most consequential because it determines whether recommendations can be stated generally.
