Abstract

This study explores the dynamics of entrepreneurship in Islamic boarding schools in the context of sharia economic empowerment, using a qualitative approach and a multiple case study design. This study compares two Islamic boarding schools with different entrepreneurial characteristics: the Mukmin Mandiri Islamic Boarding School in Sidoarjo, which focuses on coffee agribusiness with exports to Australia and Malaysia, and the Rahmatan Lil Alamain Islamic Boarding School in Nganjuk, which develops micro-enterprises based on local potential. The results show that both Islamic boarding schools implement strategic management that is adaptive to their respective contexts, with key success factors including visionary leadership based on values, integrated resource management, application of sharia economic values, and adaptability of strategies to the external environment. This study contributes to the understanding of how strategic management principles can be applied in the context of Islamic boarding schools based on sharia economics.

Abstract

Pollution air in cities in Indonesia, such as Jakarta, Tangerang, and Bandung, is especially caused by exhaust emissions from vehicle motorized, like carbon monoxide (CO) and hydrocarbons (HC), which originate from burning material burn the ones that don't perfect. Technological catalytic converters are used to reduce emissions, but converters made from metal have their own cost. This study evaluates exhaust Metallic Catalytic Converter (MCC) technology with alternative materials copper (Cu). The result shows that the MCC Cu exhaust system is significantly more effective in reducing CO and HC emissions compared with exhaust without the original equipment manufacturer (OEM) catalyst and exhaust. The average CO emissions are 2.13 %Vol and HC emissions are 198 ppmVol, lower compared to the second type of exhaust. Findings This shows that MCC Cu exhaust is not only more effective in reducing danger but is also more economical compared to catalytic converters made from metal noble, offering a solution sustainable and affordable for problem pollution air from vehicles.

Abstract

The renewable energy system (RES) has recently become hot topic due to its unlimited, green energy potential, and the maturity of its technology. A solar charging controller (SCC) is required to regulate parameters for the battery and is an essential component for sustainable and renewable energy usage. An SCC based on a DC-DC Buck converter with cascaded proportional-integral (PI) controller is used in the system for managing the current and voltage loops, thereby preventing battery overcharging. The control parameters are determined using the Ziegler-Nichols method based on the reaction curve. A first -order system is employed due to the open-loop responses show no overshoot and oscillations. MATLAB software is used for both simulation and controller design. Simulations are conducted to validate the proposed SCC with the cascaded controller. Variations in the state of charge (SoC) are presented in two cases: without and with the controller. The SoC is set 20%, 50%, and 95%. A high SoC percentage indicates that the battery is near the full capacity, whereas a low percentage indicates that battery is near empty. Using the cascaded controller, both current and voltage responses at different SoC levels demonstrate satisfactory performance, including rapid transient responses, minimal overshoot, small ripples, and robustness.

Abstract

Many factors influence the low number of skilled vocational high school graduates. One factor that is the leading cause is the lack of instruments that can be used in the learning process, especially authentic instruments, to assess students' abilities in the psychomotor domain. Students who are dominant in the cognitive sphere are not necessarily skilled in the psychomotor realm, especially when using the equipment and making improvements to the brake system. The purpose of this study is to develop an assessment instrument that is appropriate to be used by the teacher in evaluating the psychomotor domain's abilities, specifically for the brake system competency. This research is development research that uses ADDIE models as a reference for research. ADDIE model has five stages of development that need to be considered, including analysis; (2) design; (3) development; (4) implementations; and (5) evaluation. Based on the results of the analysis and discussion of the psychomotor domain assessment instrument for the competency of the brake system that was developed to be suitable for use in the learning process. Feasibility is proven from the results of the validation of experts who get an assessment of 4.66 with a very valid category. The instrument reliability test results that get the Cronbach's alpha value of 0.895, and the value of inter-observer reliability is 0.740. In addition, the instrument is also practical when used in the learning process. This was evidenced by the acquisition of practicality test value of 3.31 and entered in the practical category.

Abstract

This research aims to analyze the improvement of cognitive and psy-chomotor abilities by integrating ACS (Automotive Circuit Simulation) in learning about vehicle body electrical systems. This research is quan-titative research with a quasi-experimental design with two groups, namely an experimental group and a control group. The data collected was analyzed using quantitative descriptive. The results of this research indicate that there are differences in prior knowledge and the acquisi-tion of practical skills among students who utilize ACS media as a learning tool for vehicle body electrical systems. Recommendations from this research include further integrating ACS into the curriculum, increasing the availability of digital learning resources, and providing additional training for educators to optimize the potential for inde-pendent and interactive learning for students through simulation. Thus, this article proposes an innovative solution to effectively support the development of students' knowledge and skills in the field of vehicle body electrical systems.

Abstract

Many students do not demonstrate optimal mastery because EFI mate-rial is considered complex and abstract, while conventional learning using engine stands has limited accessibility outside school hours. This innovation is designed to create an immersive learning experience fo-cused on reinforcing foundational knowledge regarding the identifica-tion of components, functions, and the operational flow of the EFI sys-tem. The study employs a quantitative method with a quasi-experimental design of the Non-equivalent Control Group Design type. The research sample consisted of 80 students in the 11th grade of Light Vehicle Engineering, divided into an experimental group and a control group. Data were collected through pre-tests and post-tests, then ana-lysed using ANOVA with a significance level of α=0.05. The results of the study indicate that the use of AREFI media has a significant posi-tive impact on student learning outcomes. There was an increase in the average score from 44.73 in the pre-test to 70.92 in the post-test. The ANOVA test results showed an F value of 90.217 with a significance level of 0.000 (p < 0.05), proving that the difference in learning out-comes between the two groups was caused by the use of the AREFI media. Therefore, it can be concluded that the AREFI learning media has proven to be effective as an innovative solution for visualizing abstract EFI concepts, enhancing interaction, and facilitating deep un-derstanding among vocational high school students.

Abstract

Vehicle emissions remain a major environmental challenge in urban areas, particularly in developing countries like Indonesia, where motorcycles dominate transportation. Automatic motorcycles pose specific emission control difficulties due to their engine characteristics. This study experimentally evaluates six copper-metallic catalytic converter designs installed on a 150cc automatic motorcycle under idle and 3000 rpm conditions. Exhaust emissions of carbon monoxide (CO) and hydrocarbons (HC) were measured using a gas analyzer. Grey Relational Analysis (GRA) was employed to optimize the design parameters. The E3 design (curvature height: 4 mm, diameter: 54 mm, length: 100 mm) exhibited the best performance, reducing CO to 3.72% and HC to 539 ppm. Compared to standard designs, E3 improved emission reduction by 18–36%. These findings confirm that catalyst geometry significantly influences emission control and demonstrate the effectiveness of GRA in multi-parameter optimization. The results contribute to the development of efficient, affordable catalytic converters, supporting sustainable transportation and aligning with SDG 13 goals for climate action.
