Abstract

Water efficiency in agriculture plays a crucial role in addressing climate change and freshwater scarcity challenges. Conventional irrigation systems often result in excessive water usage due to non-adaptive watering schedules. This study proposes an adaptive automatic irrigation system based on the Internet of Things (IoT) integrated with the Reinforcement Learning (RL) Q-Learning algorithm to optimize water usage. The system utilizes an ESP32 microcontroller connected to DHT22 and YL-69 sensors for real-time monitoring of temperature, humidity, and soil moisture, with data transmitted to the Firebase Realtime Database. The system was experimentally tested for 30 days under three soil moisture conditions with repeated measurements, resulting in an average sensor accuracy of 97.9% and a 70% reduction in daily water consumption compared to manual irrigation. The implementation of RL enables the system to autonomously adjust irrigation decisions based on environmental dynamics while providing remote monitoring via a web dashboard. The results demonstrate that the proposed IoT-RL solution offers an effective, intelligent, and sustainable approach for improving agricultural water resource management.

Abstract

The increasing demand for housing in Indonesia requires innovative and efficient construction systems to ensure sustainable development. This study presents the design and analysis of a lightweight steel roof structure, tittled “Gili Iyang Ubhara,” inspired by the ecological values of Gili Iyang Island in Sumenep, known for its exceptional air quality. The design integrates the concept of a green and solar roof to optimize energy use and environmental performance. The structural analysis methodology used in this research is standards of SNI 7971:2013 and SNI 1727:2020. The roof structure was then analyzed with SAP2000 software to evaluate strength, load distribution, and material efficiency. The results show that all members of the structure have strength ratios below 1.0, indicating safe performance under dead, live, and wind loads. The combination of solar panels and green roof elements contributes to reduced heat absorption and increased energy efficiency. For the record, future research is recommended to incorporate dynamic thermal–energy simulations to quantify the long-term performance of hybrid eco-roof systems under varying climatic conditions, thereby enhancing predictive accuracy for large-scale implementation.

Abstract

Micro, small, and medium enterprises (MSMEs) play a crucial role in community economic development, yet many neglect occupational safety and health (OSH) and ergonomic considerations for their workforce. An initial assessment at Gelora Bakery, a small-to-medium bakery enterprise in Jakarta, revealed significant ergonomic and safety deficiencies. Workers frequently engaged in unsafe manual handling tasks—bending awkwardly while lifting heavy loads such as flour sacks, baking material buckets, and butter containers without mechanical support. These unsafe working conditions pose a substantial risk of work-related musculoskeletal disorders (WMSDs) among workers. To address these concerns, this research employs the Rapid Entire Body Assessment (REBA), a standard ergonomic evaluation method, to systematically assess worker postures and quantify the risk of musculoskeletal injury. Based on the results of the REBA assessment, the highest score obtained was 10. This rating indicates a high-risk category and requires implementation of changes. This study formulates evidence-based recommendations for improving workplace safety and worker posture at Gelora Bakery. The implementation of ingredient storage shelves represents the primary intervention recommended to create a safer, healthier, and more efficient work environment.

Abstract

Village offices are essential for the daily functioning of the community, especially in Ketegan Rejoso Pasuruan village. To ensure the development and prosperity of the village, the local government must optimize its efforts. The preparation of the construction budget plan is a key aspect, particularly when it comes to involving the community in the planning process. This research aims to obtain a cost budget plan and project timeline for the renovation of the Ketegan Village Office, ensuring that the development process is structured and organized. The Cost Budget Plan calculations in this study refer to the Unit Price Analysis of Pasuruan City in 2023, as well as a survey of building materials and bestek (technical specifications) drawings provided. The study found that the Ketegan Village Office, a single-story building with an area of 100,75 m², will be in Ketegan Village, Rejoso District, Pasuruan Regency. The total cost required for this construction project is IDR. 173.723.000,00, with the construction scheduled to take 2 months or 60 calendar days, assuming a 7-day workweek. Achieving accurate results requires a comprehensive understanding of all the stages involved in calculating the budget plan.

Abstract

Environmentally friendly brake lining material uses a polymer composite reinforced with natural materials. Material testing of morphology, density, specific gravity, and swelling showed that composition significantly affects composite properties. Increasing the proportion of green mussel shell resulted in a rougher surface, higher density and specific gravity, and a significant decrease in swelling. The variation of paper, citrus reticulata, and perna viridis  0:50:50 had the highest degree of swelling (33.76%), while the variation of 75:12.5:12.5 showed the lowest value (0.17%), making it ideal for humid environments. The combination of orange peel and green mussel shell produces a lightweight, strong, and moisture-resistant material, making it an alternative, sustainable material for vehicle braking systems.

Abstract

The high number of motorcycle accidents due to rider negligence confirms the need for an active safety system that is able to respond to emergency conditions, while research on auto-brakes is still limited, especially in terms of the detection distance of objects which are generally only active when there are objects within 9 meters according to sensor calibration and control logic as well as the application in low-speed vehicles at least 5 km/h. This research designed an Arduino Uno-based auto-brake system with LiDAR and infrared sensors to detect objects in front of the vehicle, with a braking mechanism running a servo motor that presses the main brake. The research methods include hardware design, sensor–actuator integration, fuzzy logic programming, and stationary testing using bike-based prototypes with variations in distance and speed. The results showed that the system was able to respond effectively at a distance of 700 cm with a maximum braking angle of 40°, maintaining stability in sudden conditions, thus confirming the effectiveness of fuzzy logic-based auto-brakes in improving rider safety while opening up the direction of further research for two-wheeled adaptive safety systems.

Abstract

In the era of digital transformation, Micro, Small, and Medium Enterprises (MSMEs) are increasingly encouraged to adopt operational digitalization to strengthen internal processes. This study aims to design and preliminarily evaluate an Agile Scrum-based operational information system intended to support internal efficiency in culinary MSMEs, particularly in transaction recording, processing speed, and inventory traceability. Prior to development, manual workflows showed slow transaction entry, inconsistent handwritten stock notes, and limited visibility for daily reconciliation—conditions used as qualitative baseline indicators for assessing potential efficiency improvements. The system was developed through three Agile Scrum sprints, with requirements gathered via observation and semi-structured interviews, modeled using Unified Modeling Language (UML), and evaluated through black-box functional testing and User Acceptance Testing (UAT). Black-box testing verified that core functions executed as intended, while early UAT feedback from five internal users produced an average satisfaction score of 86% on a Likert scale, indicating positive perceptions of usability, responsiveness, and reporting clarity. These findings represent preliminary perceptual evidence rather than demonstrated operational improvement, as no quantitative measurements—such as before–after transaction time, error rates, or reconciliation accuracy—were collected. Accordingly, the study does not claim proven efficiency gains but proposes an initial design that can be refined and empirically validated through future performance-based evaluations. The study contributes by positioning internal record-keeping digitalization as a practical entry point for MSME operational strengthening and by illustrating Scrum’s contextual applicability in resource-constrained business environments.

Abstract

This Systematic Literature Review (SLR) examines the application of Educational Data Mining (EDM) in online learning from 2015 to 2025 using the PRISMA approach. Thirty-two studies were analyzed to identify the data mining techniques used, the factors analyzed, and the extent to which the literature considers the equity and accessibility dimensions. The review results indicate that EDM is widely applied to predict academic performance, identify learning behavior patterns, detect at-risk students, and analyze the use of learning resources. The dominant techniques include classification, prediction, sequence analysis, process mining, and clustering. However, the equity and accessibility aspects are rarely discussed explicitly most studies only implicitly address accessibility through digital interaction behavior, while social factors related to equity, such as learning readiness, environmental support, and the digital divide, appear in only a small proportion. Furthermore, the variety of data formats and limited course coverage limit the generalizability of the findings. Overall, this study emphasizes the need for stronger integration between educational analytics and the social dimension for EDM to more effectively support equitable distribution of quality and access to online learning.

Abstract

Liquefied Petroleum Gas (LPG) is widely utilized as a primary energy source in household and industrial applications. However, gas leakage remains a major safety concern that can lead to fire or explosion hazards. This study presents the design and implementation of an Internet of Things (IoT)-based LPG leakage detection system equipped with real-time alert notifications via the Telegram application to enhance household safety. The proposed system integrates a NodeMCU V3 ESP8266 microcontroller programmed using the Arduino IDE and an MQ-2 gas sensor capable of detecting gas concentrations between 300 and 10,000 ppm. Performance evaluation was conducted through experimental testing that measured key parameters such as gas concentration detection accuracy, system response time, and data transmission latency. When the detected gas concentration exceeds the threshold of 300 ppm, the system automatically transmits an alert message to the user’s smartphone through Telegram. The results show that the system effectively detects gas leakage events with an average response time of 23.018 seconds and an average data transmission delay of 265.76 milliseconds, remaining below the 300-millisecond standard. The novelty of this research lies in the integration of IoT-based gas monitoring with real-time Telegram bot notifications optimized for household environments, offering a more responsive and user-friendly solution compared to previous detection systems. These findings demonstrate that the developed system provides an effective and reliable approach for early detection and prevention of LPG gas leak hazards.
