Abstract

This study was conducted to determine the effect of adding a copper nickel catalytic converter on CO and HC exhaust emissions on a Honda Astrea motorcycle. The scope of this study includes an analysis of the effect of variations in the dimensions of a copper nickel catalytic converter to reduce CO and HC exhaust emissions. This study uses an experimental method to compare the levels of CO and HC emissions in standard exhausts without catalysts with exhausts using catalysts from two experiments with different dimensions. Data were taken at several engine speeds (1000 rpm to 6000 rpm) using a Gas analyzer. The results showed that the catalytic converter of experiment 2 was able to reduce exhaust emissions significantly. The results of experiment 2, with a catalyst length of 10cm, were able to reduce CO emissions by an average of 37% and HC by 47%. The highest reduction in CO occurred at 6000 RPM (85%), while the largest reduction in HC occurred at 1000 RPM (81%). The conclusion of this study is that the copper-nickel catalytic converter from experiment 2 is more effective in reducing CO and HC exhaust emissions compared to the catalyst from experiment 1 or standard exhaust without a catalyst.

Abstract

Sepeda listrik roda tiga merupakan alternatif transportasi ramah lingkungan yang memerlukan sistem suspensi optimal untuk meningkatkan kenyamanan dan keamanan pengendara di jalan Indonesia yang masih banyak rusak dan bergelombang. Penelitian ini bertujuan menganalisis fenomena keterbatasan sistem suspensi pasif sepeda listrik roda tiga Aviator AT 230 terhadap pencapaian standar kenyamanan dan keamanan khususnya pada kondisi jalan bumpy. Metode penelitian dilakukan secara eksperimental berbasis simulasi menggunakan pemodelan quarter-car dan software MATLAB/Simulink dengan memvariasikan tiga mode kecepatan (Eco, Normal, Sport) pada profil jalan bumpy. Model matematis dibangun berdasarkan parameter kendaraan dan dianalisis untuk menghasilkan nilai RMS (Root Mean Square) percepatan vertikal sesuai Standar ISO 2631-1:1997. Hasil analisis menunjukkan bahwa semua kombinasi mode kecepatan menghasilkan RMS percepatan di atas 1,25 m/s² yang dikategorikan sebagai sangat tidak nyaman menurut Standar ISO 2631-1:1997, dengan peningkatan signifikan sebesar 265% dari mode Eco ke mode Sport. Selain itu, defleksi suspensi pada semua mode kecepatan tetap dalam batas aman secara struktural. Temuan ini membuktikan bahwa sistem suspensi pasif Aviator AT 230 memiliki keterbatasan dalam menjamin kenyamanan optimal, meskipun aman secara struktural. Penelitian ini merekomendasikan penggunaan mode Eco pada jalan gunduk untuk meningkatkan kenyamanan pengendara dan memberikan dasar bagi pengembangan strategi optimasi suspensi yang lebih adaptif di masa mendatang.

Abstract

The transportation sector's reliance on fossil fuels has driven the development of converted electric vehicles as a more economical alternative. However, the performance of these converted vehicles—specifically the torque of the Brushless DC (BLDC) motor—remains suboptimal due to a lack of systematic controller parameter settings. This study aims to analyze the effects of power limit and load on the electric motor torque of a converted Honda Beat FI 110 cc, develop a mathematical model using Response Surface Methodology (RSM), and determine the optimal parameter combination. A quantitative experimental approach was employed using a face-centered Central Composite Design (CCD), resulting in 13 experimental combinations. Independent variables included power limit (50%, 80%, and 100%) and load (60, 70, and 80 kg), while the dependent variable was torque, measured using a chassis dynamometer. Data were analyzed via second-order polynomial regression, ANOVA, a lack-of-fit test, and desirability optimization. The results showed torque values ​​ranging from 42.87 to 51.81 N·m, with the highest value achieved at a combination of 80% power limit and 70 kg load. The RSM model was statistically significant (F = 17.72; p = 0.001) and showed no lack of fit (p = 0.973). Optimization identified the best conditions at a power limit of 87.88% and a load of 70.10 kg, yielding a predicted torque of 49.66 N·m and a composite desirability value of 0.8197. This study demonstrates that the RSM-CCD approach is effective for modeling and optimizing the torque of converted electric vehicles, thereby serving as a reference for more systematic controller parameter settings.

Abstract

Purpose – This study systematically maps global research trends on entrepreneurial readiness in vocational education from 2020 to 2025 and identifies implications for strengthening the Indonesian vocational education system (SMK). Entrepreneurial readiness is a strategic national priority amid ongoing graduate unemployment and policy reforms, including Merdeka Belajar.Methodology – A bibliometric analysis was conducted using data from the Scopus database. After a multi-stage screening, 82 relevant publications were selected from an initial pool of 159 documents. Subsequently, the VOSviewer software generated keyword co-occurrence networks and temporal overlay visualizations, enabling the identification of thematic clusters and the evolution of research focus.Findings – The analysis identified 29 key terms within five thematic clusters: (1) Entrepreneurial Readiness, (2) Work-Integrated Learning, (3) Entrepreneurial Self-Efficacy, (4) Entrepreneurial Intention, and (5) Entrepreneurial Education. Early studies (2020–2021) centered on employability skills, curriculum design, and work-integrated learning, while recent research (2022–2025) focused on digital competence, self-efficacy, leadership, and innovation. These thematic trends correspond to Indonesia's digital economic growth and national reforms in vocational education under the Merdeka Belajar framework. However, notable gaps persist in bibliometric studies tailored to the Indonesian vocational education context, specifically highlighting the need for targeted research.Contribution – This study maps the field of entrepreneurial readiness research in Indonesian vocational education, strengthens the integration of the Theory of Planned Behavior with work-integrated learning and digital competence, and offers actionable policy insights for redesigning SMK curricula under the Merdeka Belajar framework.

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.
