Abstract

Motivation is crucial in education, driving the learning process. Cooperative Problem-Based Learning (CPBL), an extension of Problem-Based Learning (PBL), enhances critical thinking and student motivation, especially in mechanical engineering education. However, research on CPBL’s motivational impact is limited. The MUSIC Model—comprising Empowerment, Usefulness, Success, Interest, and Caring—provides a framework to boost motivation. This study examines the synergy between CPBL and the MUSIC Model in mechanical engineering education. A mixed-method approach with a Sequential Explanatory design was used, involving students from a public university in Surakarta, Indonesia, enrolled in a sustainability-related course. Quantitative data were collected through MUSIC-based questionnaires, and qualitative data were obtained from semi-structured interviews. Descriptive statistics (SPSS) and the Miles & Huberman method analyzed the data. Results show that 60-90% of students report very high motivation across all components. The study suggests CPBL fosters motivation and develops essential 21st-century skills, preparing students for future challenges.

Abstract

Wot Batu merupakan karya seni instalasi dalam skala ruang yang diciptakan oleh Sunaryo pada tahun 2015 di Ciburial, Bandung. Konsep Lebenswelt (dunia kehidupan), sebagaimana dikemukakan oleh Edmund Husserl, hadir dalam karya ini melalui fenomena lingkungan sekitar, intuisi, emosi, serta pengalaman dan ingatan pribadi Sunaryo. Lebenswelt tersebut diwujudkan dalam suasana, bentuk, tekstur batu, dan tapak Wot Batu, yang merefleksikan pandangan pribadi dan spiritualitas Sunaryo. Penelitian ini menggunakan pendekatan kualitatif dengan metode deskriptif-analitis untuk memahami bagaimana makna Lebenswelt dalam Wot Batu diterima oleh masyarakat. Data dikumpulkan melalui kajian literatur untuk memahami latar belakang Sunaryo serta observasi langsung terhadap elemen fisik Wot Batu. Wawancara mendalam dilakukan dengan staf dan pengunjung guna menggali perspektif mereka. Hasil analisis menunjukkan bahwa pengalaman spiritual Sunaryo dalam Wot Batu dapat terbaca oleh orang lain, meskipun dengan tingkat pemahaman yang berbeda.

Abstract

The implementation of thermal insulation within the walls of building constitutes a pivotal strategy aimed at mitigating cooling loads and augmenting energy efficiency, particularly in tropical climate conditions. In the preceding decade, scholars have progressively utilized both empirical and computational methodologies to evaluate the efficacy of insulation under diverse environmental and material parameters. Aims:  This study undertakes a comprehensive review of methodological frameworks in the domain of thermal insulation research for building walls conducted between 2020 and 2024, with an emphasis on hybrid experimental design that integrate physical measurements with digital simulations to yield more accurate, dependable, and contextually pertinent data. Methodology and results: A systematic literature review (SLR) encompassing 52 scholarly articles was performed, categorizing the studies into four distinct classifications: field studies, laboratory-based investigations, digital methodologies (e.g., EnergyPlus, TRISCO, ABAQUS), and hybrid methodologies. Among these, digital experimentation emerged as the most predominant methodology, with EnergyPlus identified as the most frequently utilized instrument. Research employing hybrid methodologies demonstrated enhanced analytical rigor through cross-validation, versatile scenario exploration, and comprehensive thermal performance assessment. Conclusion, significance, and impact study: Combining empirical data with digital experimentation significantly improves the precision and contextual relevance of thermal insulation evaluation. Hybrid methodologies facilitate the simulation of prolonged or extreme conditions that are often impractical to physically assess. Calibrated digital instruments such as EnergyPlus, TRISCO, ABAQUS, Delphin, and COMSOL are particularly effective. Especially for tropical climates, hybrid methodologies offer a robust framework for improving the design, applicability, and performance of building insulation systems.

Abstract

Recycling used face masks into useful products is an alternative way to reduce the accumulation of medical waste during the COVID-19 period. The main objective of this study was to determine the effect of injection molding parameters of barrel temperature, molding temperature, and cooling time on tensile strength and plastic shrinkage during the recycling process of used disposable face masks. The study utilized a Design of Experiment (DoE) using the Taguchi Orthogonal L9 method. In this current study, the barrel temperatures were set at 170oC, 190oC, and 220oC. with the molding temperatures used are 45°C, 60°C, and 75°C, while the values of cooling time were 26s, 43s, and 52s. The tensile test was carried out according to the ASTM D638 type V standard for measuring the strength of materials. The findings demonstrate that the most important factor in achieving the highest tensile strength is the molding temperature, which contributes 34.54% and is best combined with a barrel temperature of 170°C, a molding temperature of 60°C, and a cooling period of 52s. By contributing 54.40% to the parameter combination of barrel temperature of 170°C, molding temperature of 45°C, and cooling time of 52s, the molding temperature becomes the most crucial factor to produce the least amount of shrinkage
