Abstract

Dengan perkembangan teknologi informasi, komunikasi, perdagangan, dan sistem pembayaran telah memunculkan inovasi baru seperti munculnya alat pembayaran uang digital dengan perkembangan teknologi. Penggunaan uang elektronik di Indonesia pada saat ini mengalami peningkatan yang pesat dari tahun ke tahun, maka Bank Indonesia meluncurkan kebijakan berupa QRIS (Quick Response Indonesian Standard). Jenis penelitian ini merupakan penelitian deskriptif dengan menggunakan pendekatan kuantitatif. Dengan populasi yaitu pelaku usaha yang ada di Kabupaten Asahan. Analisis penelitian dilakukan menggunakan aplikasi SmartPLS 4.0 dengan menggunakan SEM PLS. Hasil dari penelitian ini yaitu variabel Penggunaan Sistem Pembayaran QRIS berpengaruh signifikan terhadap Peningkatan Pendapatan Pelaku Usaha. Jadi Penggunaan sistem pembayaran QRIS memberikan dampak positif yang signifikan terhadap pendapatan pelaku usaha. Hal ini menunjukkan bahwa QRIS dapat menjadi salah satu alat yang efektif dalam meningkatkan kemudahan transaksi dan aksesibilitas pembayaran bagi pelaku usaha.

Abstract

The Memorabilia Building “De Javasche Bank” of Bank Indonesia in Padang currently functions as a historical architectural museum, which formerly served as the economic center of West Sumatra. This study aims to analyze the historical architectural elements of the building, particularly the pyramidal roof form, through Roland Barthes’ visual semiotics analysis. Using a descriptive qualitative method, the research explores the denotative and connotative meanings of the roof as a visual sign representing the relationship between colonialism, local culture, and modernity. The findings reveal that the pyramidal roof not only serves as structural protection but also carries symbolic meanings that reflect architectural adaptation to the tropical climate and the representation of colonial power. The transformation of the building’s function into a museum signifies a shift in meaning, from a symbol of colonial economic dominance to a medium for cultural and historical preservation. These findings imply the importance of museum interpretation strategies that present visual narratives contextually and educationally, enhancing public awareness of colonial architectural values. Moreover, the results can serve as a reference for developing preservation policies based on the symbolic meanings embedded in architectural heritage. This study contributes to the discourse on historical architecture and deepens the understanding of visual elements as carriers of historical narratives. The results of this analysis can be used in the sustainability of cultural preservation in the city of Padang.

Abstract

Conventional organic waste chopping machines predominantly utilize horizontal shaft configurations, which are highly susceptible to asymmetric load distribution and present ergonomic challenges during maintenance. As an innovative solution, this study presents the conceptual design of a vertical-shaft chopping machine integrated with a hydraulic-actuated top-head system to enhance the efficiency of particle size reduction. The scope of this research is strictly confined to theoretical mathematical modeling and numerical simulations. The design process complies with the ASME B106.1M standard for transmission shafts and EN 13683 for operational safety parameters, excluding experimental fabrication. A comprehensive analysis was conducted on three primary materials—Mild Steel (MS), Stainless Steel 304 (SS 304), and Stainless Steel 316L (SS 316L)—under fluctuating waste loads ranging from 10 kg to 35 kg. The analytical results demonstrate several crucial findings: the minimum safe shaft diameter ranges from 16 mm (utilizing SS 316L at a 10 kg load) to 28 mm (utilizing MS and SS 304 at a 35 kg load). Furthermore, the agitator's power requirement exhibits a strictly linear increase corresponding to the applied load (from 1.34 kW to 4.68 kW), whereas the hydraulic system operates efficiently with a constant power profile of 0.25 kW. Overall, the vertical shaft configuration significantly promotes symmetrical force distribution, while the hydraulic system ensures safe and immediate access to the chopping chamber. The proposed design demonstrates substantial structural, operational, and ergonomic advantages, establishing a robust theoretical foundation for future development and experimental fabrication.

Abstract

The community service program in Kampung Mayak, Mayak Village, Curugbitung Subdistrict, was implemented in response to the community's limited access to technology and suboptimal understanding of technology, health, and environmental management. This activity aims to increase the basic knowledge capacity of students and the community through the implementation of integrated socialization designed systematically. Community service partners included early childhood education centers, kindergartens, elementary schools, junior high schools, and the Mayak Village community. The implementation method used a participatory, interactive, and collaborative approach with the Participatory Action Research (PAR) method through health demonstrations, creative garden creation, basic computer training, tutoring, afternoon exercises, and village mutual assistance. Evaluation was conducted after direct observation, independent practice, and brief question and answer sessions to measure participants' understanding and behavioral changes. The results showed an increase in the fine motor skills of PAUD children, the habit of clean living among kindergarten and elementary school students, the strengthening of environmental literacy through the recycling of used bottles, and an increase in digital literacy among junior high school students. Collaborative activities also strengthened social interaction and community awareness of health and environmental hygiene. Overall, the integrated socialization model was effective in integrating technology, health, and environmental aspects. These findings are significant because they present realistic, applicable, and potentially sustainable empowerment practices for schools and the Mayak Village community.
