Abstract

Indonesia has one of the highest numbers of accidents within ASEAN country. Accident reduction program has been established namely National Public Safety Plan (RUNK) established by the government has not show a significant impact. Weak public transport in Indonesia caused the population to attempt to solve it by using personal vehicle. During the last decade, the motorcycle is the star of transport mode choice in almost all Indonesian regions, however, as the number of motorcycle on the highway increase, making the probability of motorcyclist accidents increased as well. Based on the above conditions, the study has evaluated students’ preferences on reducing accident severity as a result of an accident. Furthermore, the research will be conducted in Makassar and Surabaya. Using Binary Logit Analysis it can be inferred that the probability of respondents who are willing to reduce the serious severity in Surabaya is 78.63% whilst in Makasar 94,73%. Considering on reducing slight injury respondent in Surabayawho are willing to reducing the injury is 66,66%, while at Makasar is 93,37%.

Abstract

This study aimed to determine the improvement of student’s mathematics learning outcomes by implementhing the Guided Discovery Learning learning model on trigonometric material in grade X of SMKS (Vocational High School) Salafiyah Syafi’iyah Randangan, academic year 2023/2024. The data in this study was collected through teacher activity observation sheet, student activity observation sheet (given to 20 student), and learning outcome test. The research indicators were: the results of observation of teacher activities in managing learning activities reached at least 75%, the result of observation of student activities in receiving learning activities reached the “Active” criterion with a minimum of 75%, the result of the assessment of mathematics learning outcomes were at least 75%, and all students reached the minimum completeness criterion (75). Based on the analysis, applying the Guided Discovery Learning learning model to trigonometric material could improve students’ mathematics learning outcomes in two cycles after learning improvements were made from cycles I to II. this was marked by the escalation result of 1) observation of teacher activities in managing learning (cycle I 55,98%, and cycle II 97,06%), 2) observation of student activities during the learning process (cycle I 40%, and cycle II 93,3%), and 3) yhe average of student mathematics learning outcome (12 student or 60% in cycle I, and 18 student or 90% students completed in cycle II).

Abstract

This study analyzes the performance index of the Probolinggo-Banyuwangi Toll Road Package 3 construction project using the Earned Value Method (EVM) to evaluate time and cost performance. Infrastructure projects, particularly toll roads, play a vital role in enhancing regional connectivity and economic growth. However, large-scale construction projects frequently face challenges such as cost overruns and delays. The Earned Value Method provides a comprehensive framework for measuring project performance by comparing planned costs, actual expenditures, and completed work. This research employs key performance indicators, including Budgeted Cost of Work Scheduled (BCWS), Budgeted Cost of Work Performed (BCWP), and Actual Cost of Work Performed (ACWP), to determine the Schedule Performance Index (SPI) and Cost Performance Index (CPI). The findings reveal that the project experienced schedule delays, with an SPI of 0.93, indicating that work progress was behind the planned schedule. However, the project maintained cost efficiency, as shown by a CPI of 1.06, reflecting lower actual costs than budgeted. The study highlights the importance of continuous performance monitoring using EVM to identify potential risks, optimize resource allocation, and support timely decision-making. The results provide valuable insights for project managers to improve efficiency and ensure project success in large-scale infrastructure developments.
