Abstract

MSMEs play a significant role in the Indonesian economy, but many face challenges in utilizing digital technology to expand their markets. Aries Craft Rajut, a handicraft MSME, needs practical guidance to utilize e-commerce platforms such as Shopee in an effort to increase product visibility and sales. This community service activity aims to empower Aries Craft Rajut through training in creating and managing Shopee accounts. The implementation method includes direct assistance, preparation of technical guides, account creation simulations, and product uploads. Evaluation is carried out through monitoring the use of Shopee accounts and consumer interactions. The results show that participants are able to create accounts, upload products with attractive descriptions, and understand the promotional features on Shopee. This activity increases the digital literacy of MSME actors, expands market access, and strengthens business sustainability. Continuous assistance is proposed to ensure effectiveness and consistency in e-commerce account management.

Abstract

The refrigeration sector significantly contributes to global warming due to the high Global Warming Potential (GWP) of commonly used refrigerants. This study experimentally investigates the feasibility of using R290 as a low-GWP substitute for R404A in freezer applications. Although R290 and R404A have similar normal boiling points, their GWP values differ significantly (3 for R290 vs. 3922 for R404A), making R290 a more environmentally friendly alternative. Experiments were conducted on a freezer originally designed for R404A with a 1/3 HP compressor and a refrigerant charge of 170 g. After baseline testing with R404A, the system was retrofitted with R290, using an optimized charge of 62.9 g. The system's performance was analyzed over 120 minutes, with energy and exergy evaluations conducted at 60 minutes, when the cabin temperature stabilized. Results from energy analysis indicate that replacing R404A with R290 led to a 6.1% increase in cooling capacity, a 6.0% reduction in power consumption, and a 12.4% improvement in COP. Exergy analysis showed that total irreversibility decreased from 318.1 W (R404A) to 289.8 W (R290), with compressor irreversibility being the dominant factor (50.8% for R404A vs. 51.3% for R290). The findings confirm that R290 enhances system performance by reducing irreversibility and energy consumption. These results highlight R290 as an energy-efficient and environmentally friendly alternative to R404A, providing both operational cost savings and reduced environmental impact. However, to achieve optimal performance, compressor lubricant replacement is recommended when transitioning to R290.

Abstract

Optimizing AC system performance is important to optimize energy consumption, especially at partial load. The aim of this research is to obtain a performance model of the central AC system based on its operational conditions which include environmental air conditions, heat load conditions and other operational parameters, so that the performance of the AC system can be optimized which includes cooling capacity, power consumption and energy efficiency ratio. Data is obtained by experiment, then analyzed by Response Surface Methodology (RSM) to obtain optimal system performance. This research resulted in models of AC performance with coefficient of correlation (R2) of 0.9745, 0.2041 and 0.8965 for cooling capacity, power consumption and EER respectively. By analysis of varians for models, it is obtained that Model F-values are 9920.83, 313.45, and 2245.59 for cooling capacity, power and EER respectively, and implied that the models are significant. The Adequate precision ratios were 1078.33, 93.08, and 344.32 for those parameters respectively, and indicated the adequate signals. The optimum results obtained were a cooling capacity of 46.7 kW, compressor power consumption of 4.48 kW, and an energy efficiency ratio of 8.5.

Abstract

Bangsa Indonesia terdiri dari 1.340 suku yang tersebar di 17.504 pulau yang dibingkai oleh “Bhinneka Tunggal Ika”. Salah satu yang merajut dengan apik keberagaman suku bangsa di Nusantara ialah Islam. Tujuan penelitian ini ialah mencari jejak aktor yang menyebarkan agama Islam sejak ratusan tahun yang lalu di suku Mandar khususnya di Kabupaten Majene. Untuk mencapai tujuan tersebut menggunakan pendekatan kualitatif deskriptif dengan metode survei benda-benda arkeologi untuk melihat bentuk, ruang, dan waktu, kemudian mengklasifikasi dan menginterpretasikan temuan artefak yang terkait dengan topik. Di dapat pola persebaran makam para ulama di Banggae yakni makam ulama Syekh Abd. Manan dan Tuan Dicolang, di wilayah Pamboang terdapat makam Suryodilogo dan Syekh Muhammad Ali, sedangkan di Sendana ada makam Syekh Zakaria, Tuan Dimelayu, dan Tosalama di Salobulo yang bernama Syekh Syain. Para ulama perintis agama Islam berhasil menjadi perekat suku bangsa dan menjadikan Islam sebagai identitas komunal bagi suku Mandar, serta menjadi motor penggerak dalam kehidupan sosial ekonomi dan budaya

Abstract

The U building is the college building for the Department of Refrigeration and Air Conditioning, Bandung State Polytechnic. However, during the afternoon teaching, the third floor is often complained of feeling hot and disrupting the teaching and learning process. This is caused by the size of the window on the third floor is too large and does not use any shade. This research was conducted to determine the OTTV value of the existing U Building and then investigate the potential for improving the OTTV value by changing window glass materials or adding shading such as window film. This study used primary and secondary data collection methods. The primary data consisted of: building dimensions, glass dimensions, door dimensions, ambient temperature, inside temperature, wall and glass surface temperatures, and glass types. Meanwhile, some secondary data, namely building U as built drawings, wall specifications, and glass specifications used. It was found that the existing OTTV value of the Lecture U Building reached 39.78 W/m2 where this value was above the SNI 03-6389 2011 standard. By investigating the installation of shading such as window film and double glass it was possible to minimize the building's OTTV value to 36.78 W/m2 for window film and 33.86 W/m2 for the addition of double glass accompanied by window film.

Abstract

Abstract This community service program aims to empower Micro, Small, and Medium Enterprises (MSMEs) in Bakit Village by improving product identity and utilizing simple technology. The activity focused on Mrs. Yul’s bread business, which previously had a label but lacked attractiveness due to design limitations. The methods used included an initial survey to identify business potential and challenges, direct mentoring in creating a new logo with a simple design application, and socialization to provide knowledge on branding and digital promotion. The results indicated that the new and more representative logo strengthened the product identity and enhanced its visual appeal, while the socialization activities increased MSME actors’ understanding of promotional strategies and technology-based business development. This program demonstrates that simple improvements through branding and digital utilization can serve as an initial step to enhance the image, competitiveness, and sustainability of local MSMEs. Abstrak Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mendukung pemberdayaan UMKM di Desa Bakit melalui peningkatan identitas produk dan pemanfaatan teknologi sederhana. Fokus pendampingan diberikan pada usaha roti milik Ibu Yul yang sebelumnya telah memiliki label, namun tampilannya masih sederhana dan kurang menarik. Metode yang digunakan meliputi survei awal untuk mengidentifikasi potensi dan kendala usaha, pendampingan langsung dalam pembuatan logo baru menggunakan aplikasi desain sederhana, serta sosialisasi mengenai pentingnya branding dan pemanfaatan media promosi digital. Hasil kegiatan menunjukkan bahwa logo baru yang lebih representatif mampu memperkuat identitas produk dan meningkatkan daya tarik visual, sementara sosialisasi memberikan pemahaman bagi pelaku UMKM mengenai strategi promosi dan pengembangan usaha berbasis teknologi. Pendampingan ini membuktikan bahwa perbaikan sederhana melalui branding dan teknologi digital dapat menjadi langkah awal dalam meningkatkan citra, daya saing, serta keberlanjutan UMKM lokal.
