Abstract

This study examines the effect of combustion rate on CPKO (Crude Palm Kernel Oil) droplets with and without additives and catalysts, focusing on improving its combustion efficiency given that CPKO's primary component, palmitic acid (C16), inherently exhibits poor combustion characteristics. By incorporating fennel oil a bio-additive containing anethole with its conjugated cyclic structure capable of generating a magnetic field to weaken CPKO's molecular bonds and tartaric acid a highly electronegative catalyst that disrupts glycerol linkages the research demonstrates a significant enhancement in combustion rate, confirming the positive impact of these additives on CPKO's thermal decomposition.

Abstract

The Free Nutritious Meal Program (MBG), launched nationally in January 2025 under Presidential Regulation No. 83 of 2024, is a government strategy to improve student nutrition and accelerate stunting reduction in Indonesia. This study aimed to describe student satisfaction levels and eating behavior patterns, and to analyze the relationship between satisfaction and students’ perceived eating behavior changes at SMPN 2 Gondang, Tulungagung. A quantitative cross-sectional design was employed with a single data collection point. Of 719 students (Grades VII–IX), 258 were selected via stratified random sampling (Slovin formula, e=5%): Grade VII n=90, Grade VIII n=87, Grade IX n=80. A structured questionnaire was used: Section B measured satisfaction across six domains (food taste/appearance, portion/adequacy, menu variety/nutrition, service/timeliness, hygiene/food safety, and overall satisfaction) using a 4-point Likert scale; Section C measured current eating behavior (C.1–C.4: meal frequency, vegetable/fruit intake, protein consumption, snacking habits) and students’ self-reported perception of behavior changes since joining MBG (C.5). Data were analyzed using descriptive statistics and Spearman correlation (α=0.05). Results showed 77.9% of students were satisfied overall (mean=3.07). Highest satisfaction was for hygiene/food safety (mean=3.42); lowest for menu variety (mean=2.71). Eating behavior was generally positive: 53.3% regularly had lunch every day and 50.2% always finished the protein served. Snacking habits and fruit consumption remained suboptimal. Students’ self-reported perceptions indicated positive behavior changes since MBG, most strongly for lunch regularity (mean=3.24). A moderate positive correlation was found between total satisfaction and perceived behavior change (r=0.41, p<0.001). Menu diversity improvement and local food adaptation are the primary areas requiring intervention.

Abstract

Work in Process (WIP) dry-marinated chicken fillet is a semi-finished product that remains highly susceptible to microbial contamination before the cooking stage. Inadequate control of storage time and temperature during WIP handling may accelerate bacterial growth, thereby reducing product quality and compromising food safety. This study aimed to evaluate the effects of storage time and temperature on the Total Plate Count (TPC) of dry-marinated chicken fillet during the WIP stage. The study employed an experimental design by storing dry-marinated chicken fillets under different storage temperatures and holding times. Total Plate Count analysis was conducted using the standard pour plate method, and the obtained data were analyzed using analysis of variance (ANOVA) to determine the significance of treatment effects. The results demonstrated that both storage time and temperature significantly affected (P < 0.05) the TPC values. Increasing storage duration consistently increased bacterial populations, while higher storage temperatures accelerated microbial proliferation compared with refrigerated storage. The interaction between storage time and temperature indicated that improper WIP handling substantially increased the microbiological risk before the cooking process. Although dry marination may contribute to slowing bacterial growth through reduced water activity and antimicrobial effects of seasoning ingredients, these effects were insufficient to inhibit microbial proliferation during prolonged storage. Therefore, maintaining refrigerated storage and minimizing WIP holding time are essential to preserve microbiological quality and ensure compliance with food safety standards. These findings provide practical recommendations for optimizing WIP handling procedures and strengthening Hazard Analysis and Critical Control Point (HACCP)-based quality management in poultry processing industries.

Abstract

Digital Twin technology has emerged as a promising approach for improving structural health monitoring (SHM) in smart buildings through real-time data integration, virtual modeling, and predictive analysis. However, a comprehensive theoretical framework integrating Digital Twin concepts within SHM systems remains limited in civil engineering research. This study aims to develop a theoretical Digital Twin framework for structural health monitoring in smart buildings using a literature review approach. The review examines previous studies related to Digital Twin, Building Information Modeling (BIM), Internet of Things (IoT), sensor technologies, and artificial intelligence in smart infrastructure applications. The findings identify key components and integration mechanisms required to support real-time monitoring, anomaly detection, and predictive maintenance of building structures. The proposed framework contributes to the development of intelligent, resilient, and sustainable smart building systems and provides a conceptual foundation for future research and practical implementation in civil engineering.

Abstract

Biology education in higher education faces significant challenges in fostering conceptual understanding, critical thinking, and scientific inquiry skills among students. Traditional teacher-centered instruction often positions students as passive recipients of information, limiting their engagement in knowledge construction. Consequently, active learning strategies have gained considerable attention as effective approaches to improve the quality of biology education. This review aims to examine the implementation of active learning strategies in higher education biology through three major pedagogical approaches: Inquiry-Based Learning (IBL), Problem-Based Learning (PBL), and the Flipped Classroom model. A literature review methodology was employed to synthesize findings from previous studies concerning the implementation of active learning in biology education. The findings indicate that Inquiry-Based Learning effectively enhances scientific reasoning, investigative skills, and conceptual understanding. Problem-Based Learning promotes critical thinking, collaborative learning, and the application of biological concepts to authentic problems. Meanwhile, the Flipped Classroom model encourages self-directed learning and optimizes classroom interaction through active discussions and problem-solving activities. Integrating these approaches provides a promising framework for developing meaningful, student-centered biology instruction that supports the acquisition of twenty-first-century competencies.

Abstract

Accurate and stable temperature control is essential in laboratory-scale thermal processing, as it directly influences process stability, operational safety, and experimental reproducibility. However, many laboratory thermal systems still rely on manual regulation or simple heating mechanisms without adequate feedback control, resulting in temperature fluctuations and inconsistent performance. This study presents the design and implementation of an embedded temperature control system for laboratory-scale thermal processing, using pyrolysis as an application case study. The proposed system is based on a closed-loop control architecture that integrates a K-type thermocouple, a microcontroller-based control unit, and an electrical heating actuator. A hysteresis-based on–off control strategy is implemented to regulate the heating process and maintain the desired temperature setpoints. The system performance is experimentally evaluated at operating temperatures of 300 °C, 400 °C, and 500 °C under different processing durations. Experimental results demonstrate that the developed system provides stable and reliable temperature regulation across all tested conditions. The system exhibits a rapid heating response, minimal overshoot, and acceptable steady-state temperature deviations, even at elevated operating temperatures. Long-duration operation confirms the robustness and reliability of the control strategy. These results indicate that the proposed embedded temperature control system offers a practical and cost-effective solution for laboratory-scale thermal processing applications requiring stable and repeatable temperature control.

Abstract

Smartdrybox represents an innovative clothing dryer designed to mitigate electrical energy consumption and carbon emissions by harnessing waste heat from air conditioning (AC) systems. Grounded in the 6R framework (Reuse, Reduce, Rethink, Recycle, Repair, and Replace), this system integrates an Internet of Things (IoT) mobile application to facilitate real-time drying monitoring. The primary objective of this development is to present an energy-efficient solution tailored for residential households, boarding houses, and micro-scale laundry enterprises, thereby decreasing reliance on conventional electric dryers. Structurally, the Smartdrybox consists of a cabinet drying enclosure coupled to the AC exhaust outlet via an adjustable duct system. A built-in humidity sensor quantifies the moisture level of the garments, while a diffuser ensures uniform airflow distribution. An integrated microcontroller processes the acquired sensor data and transmits telemetry to the user through a dedicated IoT application. Furthermore, automated notifications are generated upon completion of the drying cycle, with drying durations fully adjustable to meet specific operational requirements. This innovation yields several distinct advantages, including the valorization of AC thermal waste (Reuse), the integration of IoT to optimize temporal efficiency, and a modular design compatible with diverse air conditioning configurations. Additionally, the system ensures fabric preservation across various textile types due to the absence of auxiliary heating elements. By synthesizing the 6R principles, IoT-driven automation, and energy recycling, the Smartdrybox aligns with green technology and smart home paradigms, demonstrating substantial potential for future research and development.
