Abstract

Stainless-steel passenger coaches are the most operated passenger trains in Indonesia, which are manufactured by the Indonesian railway industry, (PT. INKA), from its first launch to the last generation of trains. PT. INKA still keeps innovating to improve the performance of these trains. Nowadays, this passenger coach is being developed to reach a speed of more than 120 km/hour, while keeping the stability, ride quality index, and ride comfort index during operation. This new train would be called a stainless-steel new generation (SS-NG) passenger coach. To reach the target, one of the methods is redesigning the old bogie structure of the stainless-steel passenger coach. The purpose of this research is to design a new bogie for the SS-NG passenger coach and analyze its dynamics during operation at high-speed using multibody simulation. The result was then compared to the existing passenger coach (SS-2018) which was structured by the old bogie one. Sperling’s method was utilized for evaluating the ride comfort index of all designed trains. As a result, the SS-NG with a new bogie design showed stable operation and gave an acceptable ride comfort index based on Sperling’s method even though travels at 240 Km/h in speed. The results will be important for improving the performance of any train, especially the SS-NG passenger coach which will be fabricated by PT. INKA.

Abstract

This study aims to determine the implications of accounting information systems (AIS) as a business strategy for SMEs in Madiun City. Economic digitalization has a major effect on SMEs. One of the implications (Angelina Wijaya Tan et al., 2024) of this economic digitalization is the transformation carried out by SME actors into the digital era, including the use of Accounting Information Systems (AIS). Efficiency is needed by SMEs in order to keep up with the changing times. The use of this AIS can improve the reporting process and business processes carried out by SMEs. Another advantage (Ari Rohmana & Hwihanus Hwihanus, 2023) of using this AIS is to avoid recording errors and reduce waste. It can be seen that AIS has an important role in the business processes carried out by SMEs. The research method used is qualitative research. The respondents used were SMEs in Madiun City.

Abstract

This study compares the effects of financing to deposit ratio (FDR) and bank size (firm size) on return on equity through BOPO as an Intervening Variable at Islamic People's Economic Bank (BPRS) in Indonesia. The data collection method is done through indirect observation method in the form of secondary data from Sharia People's Economic Bank monthly financial statements (BPRS). Using a purposive sampling technique, 60 BPRS data were included in the sample. Data analysis using Eviews version 9 tool involved path analysis. While FDR, BOPO, and Size had a significant negative impact on profitability, the T test results indicated that it had a significant positive impact but had no significant negative effect on profitability, while NPF was able to mediate FDR, BOPO, and SIZE on profitability, while NPF was unable to mitigate the impact on earnings.

Abstract

This community service program aims to enhance Islamic-based investment literacy among the young community of Madiun City. The low level of Islamic financial literacy in Indonesia, which only reached 9.14% (OJK, 2022), indicates the need for educational and practical efforts to increase youth understanding of Sharia-compliant investment principles. The program was implemented through structured Islamic investment literacy training consisting of theoretical sessions, case studies, interactive discussions, and practical simulations. A total of 24 participants, comprising students and young community members, took part in the activity. The pre-test results showed an average score of 44.25, which increased to 78.04 in the post-test, indicating a 33.79% improvement. In addition to cognitive gains, participants also demonstrated positive changes in their attitudes toward ethical and halal investing. This program effectively improved participants’ understanding, skills, and awareness of Islamic investment and contributed to strengthening Islamic financial inclusion at the local level. It is expected that the young generation will become agents of change who promote ethical, responsible, and sustainable financial practices.
