Abstract

Heating, Ventilating, and Air Conditioning (HVAC) systems often suffer from significant energy wastage due to their inability to adapt to real-time environmental changes, leading to high operational costs. Although Proportional-Integral-Derivative (PID) controllers are widely used for their simplicity and reliability, they struggle to handle the complex dynamics of modern environments, requiring advanced optimization to enhance efficiency. This study aims to optimize PID controllers by integrating the Queen Honey Bee Migration (QHBM) algorithm to improve HVAC performance, energy efficiency, and adaptability. The research method employs an experimental approach that compares the performance of conventional PID controllers with PID controllers optimized using the QHBM algorithm under dynamic environmental conditions. The results show that the PID-QHBM system significantly outperforms the conventional PID system, achieving a rise time of 0.2649 seconds and a settling time of 1.6874 seconds with an almost negligible steady-state error of 9.4991e-08. Although it experiences a slight overshoot of 16.3810%, the system stabilizes quickly and maintains the target temperature efficiently. In contrast, the conventional PID controller exhibits slower response characteristics, with a rise time of 1.3730 seconds, a settling time of 2.5144 seconds, and a larger steady-state error of 0.0361. This study demonstrates that integrating the QHBM algorithm into PID controllers provides a more effective solution for real-time temperature control, offering substantial improvements in energy efficiency and system performance. The findings contribute to advancing intelligent HVAC control systems that can better adapt to environmental variations while minimizing operational costs.

Abstract

This study aims to analyze the factors that influence the residential spatial system of the Marori and Mengge ethnic groups in Wasur Village, Merauke, South Papua, in the context of their involvement in the eucalyptus oil industry as a leading tourism product of Wasur National Park. A rationalistic qualitative approach is used with the main theory of behavioral setting to examine the relationship between behavior, local culture, and spatial structure. The results of the study indicate that houses not only function as domestic spaces, but also as places for the production of eucalyptus oil, especially at the packaging stage. The overlapping use of space causes space invasion, changes in function, and the emergence of high spatial flexibility. The space of the house undergoes a temporal functional transformation, adjusting to the intensity of economic activities and cultural rituals of the community. Private, semi-public, and spiritual spaces experience shifting boundaries, which have an impact on social relationship patterns and living comfort. This study also found that social structure, customary values (Boan/marga), and division of customary areas play an important role in the formation of the spatial system. These findings are expected to be an important contribution to the development of residential architecture based on behavior and local wisdom, as well as community-based conservation area management. This study also highlights the urgency of preserving the culture and existence of indigenous tribes amidst the current of modernization and the threat of extinction.

Abstract

The use of building materials plays a crucial role in determining the quality of the built environment, particularly in the context of row housing in densely populated urban areas. This study aims to evaluate the types of materials used in the construction of row housing in Cemara Asri, Medan, with a focus on sustainability and environmental friendliness criteria. The methods employed include direct site surveys and literature studies related to the characteristics of both interior and exterior materials applied to housing units. The research findings indicate that most of the materials used—such as red bricks, ceramic tiles, clay roof tiles, and concrete ventilation blocks—possess good energy efficiency and durability potential. However, they do not fully meet sustainability standards in terms of production processes and waste management. The study also found that residents' awareness of environmentally friendly material selection remains limited, and the procurement of materials tends to follow local availability and economic considerations. These findings are expected to serve as a foundation for improving environmentally friendly material planning in row housing developments in other urban areas.

Abstract

This research aims to address the issue of uneven bandwidth distribution in large organizational networks by implementing Quality of Service (QoS) using FIFO and the Hierarchical Token Bucket (HTB) algorithm on Mikrotik routers. Uneven bandwidth distribution can disrupt productivity and operational efficiency. This study creates a fair and efficient traffic management system, allowing bandwidth allocation according to user needs. The methodology involves detailed configuration of Mikrotik RouterOS to optimize QoS with adjusted HTB settings. Testing was conducted using IPerf3 to measure bandwidth variations received by clients in different conditions, including scenarios with two and three active clients. The results indicate that the HTB method provides more stable and consistent bandwidth distribution compared to FIFO. In the two-active client scenario, the unused bandwidth by the third client is allocated to higher priority clients, demonstrating HTB's effectiveness in managing traffic priorities. This research is expected to enhance user satisfaction by providing a network that is both stable and responsive to the needs of various operational applications, and contribute significantly to the development of best practices for bandwidth management in complex organizational environments.

In the agricultural sector, the automatic identification of chili pepper varieties is crucial for improving production efficiency and quality. This study developed a chili pepper variety detection system based on characteristics using the Principal Component Analysis (PCA) method. The PCA method was used to reduce the dimensionality of chili pepper image data, thereby facilitating the classification process while retaining the key features necessary for chili pepper variety identification. The recognition system for chili pepper identification involves inputting chili pepper image data into a computer. The computer then interprets and identifies the chili pepper variety, and the test data utilizes a dataset of chili pepper images from various varieties. The research results indicate that the proposed system achieves a high level of accuracy in detecting and classifying chili pepper varieties. Consequently, this system can assist farmers and agricultural industry stakeholders in the chili pepper sorting and selection process, thereby improving operational efficiency and the quality of the harvest.

Abstract

PT Borneo Alumina Indonesia is a company engaged in processing bauxite into alumina, where the reliability of the agitator system in the seed precipitation tank plays a crucial role in maintaining continuous production. However, failures in the agitator electrical system can lead to significant downtime, resulting in operational losses and decreased production efficiency. Therefore, this study aims to design an effective preventive maintenance schedule to improve system reliability and optimize production performance. The research applies Failure Mode and Effects Analysis (FMEA), Risk-Based Maintenance (RBM), and Reliability-Centered Maintenance (RCM), supported by Weibull distribution analysis to evaluate failure characteristics and determine optimal maintenance intervals. The results show that the proposed preventive maintenance strategy is effective in improving system reliability, with an increase of up to 13% compared to conditions without preventive maintenance. The maintenance plan includes routine inspections of critical components, as well as scheduled replacements at one-, two-, and three-year intervals integrated with annual overhauls. In addition, the implementation of this maintenance schedule reduces annual downtime to 3.84%, enabling alumina production to reach up to 96% of the theoretical capacity of 1,000,000 tons per year. In conclusion, the proposed maintenance strategy not only enhances equipment reliability but also supports sustainable operational efficiency in alumina production processes.

Abstract

An inefficient packing system can result in excessive material handling activities, increased downtime, and higher occupational safety risks. One of the major issues identified in manufacturing operations is double handling, which represents a non-value-added activity that negatively affects operational efficiency. This study aims to improve the packing system by reducing double handling activities, minimizing downtime, and enhancing workplace safety through the implementation of the Plan–Do–Check–Act (PDCA) methodology. Data were collected through direct observation, interviews, and documentation of material handling activities in the production area. Root cause analysis was conducted using a Fishbone Diagram integrated within the PDCA framework to identify the factors contributing to inefficiencies in the existing packing system. Improvement actions included direct pallet utilization, workplace layout optimization, and the addition of towing equipment to facilitate material movement. The results demonstrated significant improvements, with handling activities reduced by 66.7%, handling time reduced by 86.7%, and downtime reduced by 75%. Furthermore, occupational safety risks decreased substantially due to the reduction of manual handling activities. Process capacity also improved, as indicated by the increase in handling frequency from 32 to 240 times per shift. The findings confirm that integrating PDCA with material handling optimization effectively improves operational efficiency, reduces waste, and enhances workplace safety. This study provides practical insights for manufacturing companies seeking to develop more efficient and sustainable packing systems.

Abstract

This study examines the neglect of climate-responsive design principles in contemporary residential buildings in Katsina State, Nigeria, a hot semi-arid region where indoor thermal comfort is increasingly affected by modern construction practices. Traditional Hausa vernacular architecture utilized passive cooling strategies, including thick mud-brick walls, courtyards, and natural ventilation, but these approaches have been largely replaced by sandcrete blocks and corrugated metal roofing. Using a mixed-methods approach, questionnaires were administered to 33 residents and builders in Katsina metropolis. Quantitative data were analyzed using descriptive statistics, while qualitative responses were examined through thematic analysis. The findings show that 76% of houses use cement/sandcrete block walls, 73% use corrugated metal roofing, 60% of residents experience hot indoor conditions, and 97% depend on mechanical cooling. Additionally, 82% spend ₦5,000–₦30,000 monthly on electricity. A key finding is that 52% of builders incorrectly perceive modern houses as cooler than traditional mud-brick structures, indicating a knowledge gap. The study highlights cost and aesthetic preferences as major factors influencing climate-insensitive material choices and recommends natural ventilation, roof insulation, shading strategies, and climate-responsive guidelines for Katsina State.
