Abstract

This research discusses heat transfer analysis in vehicle engine cooling systems, especially in radiators that use fin variations. The main objective is to compare the performance of several fin designs, including straight, zigzag, corrugated, and louvered, in terms of heat transfer efficiency and pressure loss. The research method adopted was a comparative study through secondary data collection from previous experimental results and numerical simulation (CFD). Quantitative descriptive analysis was used to compare key parameters such as inlet-outlet temperature difference (?T), heat transfer rate, and pressure drop. The study results show that the louvered and corrugated designs have the highest heat transfer rates, especially at medium to high air and fluid flow velocities. However, the improved thermal performance is accompanied by increased pressure loss, which requires adjustments to the fan and cooling pump capacity. The zigzag design offers a good compromise between cooling efficiency and increased mechanical load, while the straight fin tends to produce the lowest cooling efficiency, but with the lowest pressure loss.The practical implication of this study is the importance of considering the balance between increased cooling efficiency and the operational power requirements of the cooling system. Proper fin design selection can improve engine temperature stability, reduce the risk of overheat, and extend the life of engine components. In addition, the development of high thermal conductivity radiator materials and the production of more precise fins also determine the performance and service life of the radiator. Thus, the results of this research are expected to serve as a reference for the automotive industry in selecting and designing optimal vehicle radiators

Abstract

This research aims to analyze and design a web-based management information system for culinary MSMEs in Cilegon to improve operational efficiency and the quality of business decision-making. Using the Design Science Research (DSR) approach, this research identifies the functional needs of businesses through interviews, observations, and questionnaires, which are then used as the basis for system design. The developed system includes key features such as stock management, transaction recording, and automatic financial report generation. The trial results showed an increase in work time efficiency of up to 68%, a reduction in recording errors, and an increase in user satisfaction with an average usability score of 85 out of 100. The system also proved easy to use, even by users with low levels of digital literacy. The evaluation shows that the system is able to answer the real needs of MSME actors and has the potential to be replicated in other business sectors. This research concludes that a web-based management information system is an effective strategic solution in encouraging the digital transformation of culinary MSMEs, and can be a model for sustainable technology implementation in other regions.

Abstract

Quality hospital services are the main demand in the modern era that prioritizes patient satisfaction as the main indicator of the success of health services. This study aims to evaluate the quality of hospital services using a combined approach between the SERVQUAL and Quality Function Deployment (QFD) methods. The research was conducted qualitatively using in-depth interview techniques and participatory observation at one of the referral hospitals in Banten Province. The SERVQUAL method was used to identify gaps between patient expectations and perceptions of five service dimensions: tangibles, reliability, responsiveness, assurance, and empathy. The results showed that the responsiveness and empathy dimensions had the most significant gaps, indicating the need for improvement in the aspects of service speed and attention to patients. Furthermore, the QFD method was applied to translate patient needs into technical specifications of hospital services through the preparation of the House of Quality (HOQ). Some of the key patient needs identified included improving the quality of staff communication, waiting room comfort, and utilization of digital service systems. The literature review supports that the combined approach between SERVQUAL and QFD is able to produce solutions that are applicable and oriented towards systemic improvement of health services. This research makes an important contribution to hospital management in designing strategies based on patient needs as well as a reference for sustainable service development. The results also highlight the important role of service innovation in improving hospital competitiveness at the regional level.

Abstract

Pertumbuhan usaha masyarakat di kelurahan Warnasari dalam kegiatan Usaha Mikro, Kecil, dan Menengah (UMKM) menunjukkan peningkatan yang signifikan. Meskipun jumlah dan aktivitas UMKM mengalami peningkatan signifikan, sebagian besar masih kesulitan menjangkau pasar yang lebih luas karena keterbatasan dalam desain kemasan dan kurangnya pemahaman tentang strategi branding. Produk yang sebenarnya memiliki kualitas baik sering kali kurang memperoleh perhatian konsumen karena tampilan kemasan yang kurang menarik, kurang profesional serta kurang informatif. Menjawab tantangan ini, kegiatan pengabdian masyarakat menghadirkan program pelatihan dan pendampingan pemanfaatan aplikasi digital Canva untuk membuat desain label mencakup sosialisasi pengetahuan dasar branding tentang label, pelatihan penggunaan aplikasi, dan pendampingan penerapan pembuatan desain label sesuai karakter produk yang diinginkan oleh peserta. Hasil kegiatan ini menunjukkan para peserta mampu membuat desain label dengan visual yang lebih menarik, informatif, dan profesional sehingga mampu meningkatkan daya tarik di mata konsumen. Selain itu dari segi pemberdayaan, kegiatan ini juga memberikan kontribusi pada peningkatan kompetensi digital pada perempuan yang mendominasi sektor usaha ini, berupa peningkatan pengetahuan dan kesadaran peserta tentang peran penting label sebagai branding dari suatu produk dan meningkatkan keterampilan digital maupun kreativitas peserta.
