Leaf springs are one of the suspension systems that are still widely used in various modes of transport such as cars and trucks. The spring functions to support the load and reduce vibration from operational activities. This study aims to analyse the bending strength and hardness of steel leaf springs of trucks and cars resulting from tempering heat treatment. The three point bending method was used as the flexural strength testing method and the Rockwell C Hardness method testing was used for hardness testing with leaf springs in raw, tempered 460°C, and tempered 510°C conditions. From the results of the study, the highest average bending strength value of 3733,55 MPa was obtained and an average roughness value of 31,8 HR was obtained for the 510°C tempered truck leaf springs. This also applies to the 510°C tempered car leaf springs, where the average bending strength value obtained is 3392,65 MPa and the average hardness value obtained is 29,5 HR. Thus, it is recommended that tempering heat treatment that can be applied to truck and car leaf springs be carried out at 510°C to increase the bending strength and ductility of the leaf springs.

This study aims to analyze participants’ understanding and compliance with sharia principles in the sharia insurance claim process in Indonesia. Sharia insurance, which is based on the principle of mutual assistance and tabarru’ contract, is expected to provide protection in accordance with Islamic law. However, challenges arise in its operational practices, especially in the claim process. This study uses a qualitative approach by interviewing sharia insurance participants to explore their level of understanding of sharia principles, claim procedures, and challenges faced during the claim process. The results of the study indicate that participants’ understanding of sharia principles is still limited, which has an impact on their lack of clarity in undergoing the claim procedure. Some of the main challenges identified include administrative constraints, long claim processing times, and unclear claim procedures. Lack of understanding of sharia principles also worsens the smoothness of claims.

Electronic Health Records (EHRs) have become an important component in the digital transformation of the healthcare system in Indonesia. However, EHR implementation in many health facilities in Indonesia is still fragmentary and not fully integrated. The main challenges in integrating health data into the national health system are issues of interoperability, data security, and inter-institutional coordination. This study aims to identify and analyze the main challenges in integrating health data from various EHR systems into Indonesia's national health system and its impact on the quality of health services, operational efficiency, and data security. The research method used was a descriptive qualitative approach, which combined literature study and in-depth interviews with experts in the field of health information technology and health policy. A literature study was conducted to identify technical, operational, and policy challenges faced in EHR implementation in Indonesia. Expert interviews were used to validate the findings obtained from the literature and provide additional insights into the local context. Thematic analysis techniques were used to organize and interpret the data. The results showed that the lack of common data standards is a major obstacle in the integration of EHR systems in Indonesia.A total of 45% of healthcare facilities adopt HL7 standards, 30% adopt FHIR, and 25% use proprietary systems, leading to the inability to efficiently share data between institutions. In addition, data security issues are also a major concern, with many healthcare facilities yet to implement adequate security protocols. Limited coordination between health institutions also hinders wider integration. Nonetheless, EHR integration has the potential to improve operational efficiency, with up to 25% reduction in administrative time in institutions that have integrated their systems.
