<![CDATA[This study designs and implements a soil moisture monitoring system for household-scale chili plants based on the Internet of Things (IoT) using NodeMCU ESP8266 and soil moisture sensors . The system was developed to assist users in monitoring soil moisture conditions accurately to support more efficient chili plant care. The soil moisture sensor is used to detect soil moisture levels, then the data is processed by NodeMCU ESP8266 and sent via a Wi-Fi network to the IoT platform so that it can be monitored in real-time . System testing was carried out on chili plants planted in pots by observing the sensor reading response in various soil conditions. The test results showed that the system was able to monitor changes in soil moisture stably and display information with a good response. The implementation of this system on a household scale is considered effective in assisting plant watering decisions and reducing the risk of water shortages or excesses. The designed system has the potential to be further developed by adding automatic control features and cloud- based data storage to support the implementation of sustainable smart agriculture.]]>

<![CDATA[This research presents the design and implementation of an automatic gate barrier system based on Quick Response (QR) Code, integrated with Optical Character Recognition (OCR) technology for vehicle license plate verification. The system is controlled by an ESP32 microcontroller connected to a web server, enabling real-time data verification through the Internet of Things (IoT) network. The study applies the Waterfall development model, including system requirements analysis, hardware and software design, and comprehensive testing stages. Testing with 54 vehicle data samples showed that the system achieved a 70% success rate in validating both QR Code and license plate data, while 30% failed due to insufficient lighting and improper camera positioning. These results demonstrate that the system significantly improves security, efficiency, and organization of parking management, especially within university environments. The integration of QR Code and OCR technologies provides an effective solution for IoT-based automatic parking systems, enhancing both convenience and reliability for users.]]>

<![CDATA[Retail environments with high occupant density often experience crowding, which can compromise safety during emergencies, particularly when spatial layouts create constrained circulation and obstructed exits. This study evaluates the evacuation layout of Superindo Monjali, a supermarket in Yogyakarta, using Pathfinder simulation. The analysis focused on circulation geometry, aisle arrangements, cashier positioning, and exit visibility to assess how spatial configurations influence crowd movement and evacuation efficiency. Simulation results showed that, while total evacuation time (39.3 seconds) met recommended safety standards for single-storey buildings, localized bottlenecks, uneven flow distribution, and underutilization of secondary exits highlighted significant architectural limitations. These findings indicate that operational management alone is insufficient to ensure safe egress; spatial design must support efficient and balanced occupant movement. Based on the results, recommendations include improving exit visibility and accessibility, optimizing aisle and circulation layouts, and enhancing signage and wayfinding. The study demonstrates that architectural layout is a critical determinant of evacuation performance and provides a replicable framework for enhancing emergency preparedness in high-density retail settings.]]>

<![CDATA[Accurate solar irradiance forecasting is critical for the integration of floating photovoltaic (FPV) systems into power grids, particularly in tropical regions characterized by high convective variability. This study evaluates four forecasting approaches persistence, multiple linear regression (MLR), random forest (RF) and long short-term memory (LSTM) for predicting global horizontal irradiance (GHI) at Jatiluhur Reservoir, Indonesia’s largest reservoir and a prospective site for large-scale FPV development. Using only open-access NASA POWER satellite data (2021–2025), models were trained and tested for 1-hour and 3-hour ahead forecasts with lagged GHI features incorporated to enhance temporal representation. Results show that all models benefit significantly from lag features, with LSTM achieving the highest accuracy (RMSE = 91.87 Wh/m², forecast skill = 83.7%) at the 3-hour horizon. The study demonstrates that high-accuracy forecasting is achievable without ground-based measurements, provided appropriate feature engineering and model selection are applied. These findings offer a practical framework for energy planners and policymakers to support FPV feasibility studies and grid integration strategies in data-scarce tropical environments.]]>

<![CDATA[Advances in wireless communication technology face challenges in providing high channel capacity, energy efficiency, and transmitted signal quality in complex channels. Previous studies on Multiple Input Multiple Output (MIMO) with Intelligent Reflecting Surface (IRS) generally discuss theoretical models under ideal channel assumptions using the Semidefinite Relaxation (SDR) method, which exhibits high complexity and limited scalability. A research gap emerges due to the scarcity of studies on MIMO-IRS that address realistic optimization efficiency to maximize the Signal-to-Noise Ratio (SNR) in dynamic environments. This study aims to overcome these limitations through the integrated application of Alternating Optimization (AO) and Manifold Optimization (MO), which can handle non-convex problems more efficiently. The research is grounded in ontological, epistemological, and axiological aspects, employing experimental and simulation methods to optimize active beamforming at the Base Station and passive beamforming at the IRS while maintaining the unit modulus constraint. The results demonstrate that the AO-MO combination in MIMO-IRS increases channel capacity by up to 39.8%, SNR by up to 19.1%, and reduces computational time by more than fivefold compared to conventional methods without AO-MO. The contribution of this study lies in an optimization approach that efficiently enhances channel capacity and SNR without increasing computational complexity, enabling its application in wireless networks requiring high-speed and low-latency communication.]]>

<![CDATA[In a watershed, discharge data is essential to determine the flow rate of a river and is used to meet the daily water requirements of humans, plants, and animals. The Way Pisang watershed is a part of the Way Sekampung watershed, administratively located in the South Lampung Regency. In this study, the water demands analyzed include domestic, livestock, irrigation, and industrial needs. These water demands are compared with the water availability in the Way Pisang watershed. The analysis of water availability was conducted using the NRECA and FJ Mock methods, yielding results of 68.75 m³/s and 59.88 m³/s, respectively. Meanwhile, the water balance calculation was performed using the NRECA and FJ Mock methods through WEAP software. The results indicate that from January to November, the Way Pisang watershed experiences a surplus level of 63% (NRECA method), 57.7% (FJ Mock method), and 63.4% (WEAP method). Conversely, in December, it faces a deficit level of 0.62% (NRECA method), 1.37% (FJ Mock method), and 0.72% (WEAP software).]]>

<![CDATA[A four-wheeled vehicle bracket component manufacturing company experienced a surge in demand for a hook transport product. However, the production process was found to be inefficient due to the presence of non-value-added activities and barriers. The objective of the research was to identify and minimize waste in the production of spot welding, as well as to determine the takt time for hook transport production. To this end, a Value Stream Mapping (VSM) analysis was conducted, leveraging the existing VSM framework to assess the production process's efficiency for identify and eliminate non-value-added activities. The analysis revealed that the cycle process efficiency prior to the implementation of improvements stood at 74%, characterized by various forms of waste, including defects, over-processing, waiting, and motion. The subsequent improvement, as depicted in the anticipated future state value stream mapping, resulted in a 94% enhancement in cycle process efficiency, representing a 20% increase. Beyond the efficiency cycle process outcome, the takt time calculation for spot welding production set yielded a value of 52.85 seconds per product. This indicates that the takt time required for hook transport cycle production to meet consumer demand is 52.85 seconds. The implementation of the VSM method is expected to facilitate the identification and reduction of production waste, enhance efficiency, and optimize the fulfillment of demand targets.]]>

<![CDATA[This research discusses the design and construction of an automatic mineral water refilling system using fuzzy logic based on the ESP32 microcontroller. The background of this research is the increasing environmental pollution due to the use of disposable plastic mineral water bottles in the campus environment. The system is designed to be able to fill water containers automatically with IR sensor-based control and ultrasonic sensors to detect the presence of containers and water levels. The research method used is the Waterfall method which includes the planning, design, implementation, and system testing stages. The test results show that the system is able to fill water with an average effective volume of 83.2 % of the container capacity, with a safe limit for automatic stopping at a distance of less than 2 cm from the rim of the container. The implementation of Mamdani fuzzy logic allows the system to make filling decisions based on sensor conditions adaptively, resulting in efficient and accurate pump control. Thus, this system can be an innovative solution to reduce plastic waste while supporting efficient water use in the campus environment.]]>
