Abstract

This study introduces a quantitative risk analysis framework designed to evaluate the structural reliability of reinforced concrete elements within public buildings. The framework integrates non-destructive testing (NDT), specifically utilizing the Rebound Hammer and Ultrasonic Pulse Velocity (UPV) methods. Crucially, this research addresses a recognized gap in existing structural risk literature, which frequently concentrates on deterministic strength assessments without establishing a link between material degradation indicators and probabilistic risk levels. Leveraging empirical data derived from a comprehensive inspection of a public building, the study applied a holistic evaluation encompassing material quality, probability of failure, and severity of consequences to determine the risk category for each structural component. The methodological approach involved NDT-based strength estimation, statistical probability calculation, and the formulation of a risk matrix to derive quantifiable risk scores. The key findings demonstrate that variations in concrete quality, as evidenced by rebound values and UPV velocities, exert a substantial influence on the probability of structural underperformance. Structural elements exhibiting lower NDT values were consistently correlated with elevated risk scores, thus affirming the critical relationship between material deterioration and safety risk. The integrated risk matrix successfully identified priority elements necessitating early intervention, thereby validating the method's effectiveness in supporting proactive maintenance decision-making. Overall, this research underscores the imperative of combining diagnostic data with probabilistic frameworks to refine risk-informed asset management in public infrastructure. The proposed approach offers a practical instrument for stakeholders seeking to enhance structural safety planning and optimize rehabilitation strategies.

Abstract

This study investigates the determinants influencing the adoption of solar photovoltaic (PV) systems among mobile micro-enterprises in Makassar, Indonesia. Drawing upon the Technology Acceptance Model (TAM) extended with two contextual constructs Energy Needs and Ease & Support the research employs a quantitative cross-sectional design involving 30 mobile coffee vendors. Reliability and regression analyses confirm the model’s robustness, indicating that Perceived Usefulness, Technology Acceptance, and Energy Needs significantly predict the intention to adopt PV systems, while Ease & Support shows no significant effect. The study extends the application of TAM to the informal micro-enterprise context, which has rarely been explored in renewable energy adoption research. Findings highlight that perceived economic benefits and energy necessity outweigh technical convenience in shaping adoption behavior. This suggests that micro-entrepreneurs’ motivation is primarily driven by practicality and efficiency rather than ease of use. The results provide policy insights for promoting inclusive green transitions through targeted micro-financing, technical training, and supportive urban regulations for small mobile vendors. Overall, this pilot investigation offers a validated framework for future empirical studies on renewable energy adoption within developing-country micro-enterprise sectors.

Abstract

Abstrak. Kegiatan pengabdian masyarakat ini dilaksanakan dalam rangka memberikan peningkatan kompetensi teknis kepada para developer tanah kapling dalam hal pengukuran lahan menggunakan alat Total Station. Sasaran dalam PKM ini adalah developer tanah kapling. Pengukuran lahan yang akurat sangat dibutuhkan oleh developer untuk menentukan batas, luas, dan tata letak kavling agar tidak terjadi sengketa maupun kesalahan perhitungan lahan. Tujuan dari PKM adalah untuk memberikan pengetahuan dasar mengenai prinsip kerja dan fungsi Total Station, melatih keterampilan praktis dalam penggunaan alat total station untuk pengukuran lahan, membekali peserta dengan kemampuan mengolah data hasil pengukuran menjadi peta sederhana, dan mendukung profesionalisme developer dalam pengelolaan tanah kapling yang tertib dan akurat. Metode kegiatan yang digunakan berupa pelatihan teori, demonstrasi penggunaan alat, dan praktik langsung di lapangan. Hasil kegiatan menunjukkan bahwa peserta mampu memahami prinsip kerja Total Station, mengoperasikan alat secara mandiri, serta mengolah data hasil pengukuran menjadi peta situasi sederhana. Kata Kunci: pelatihan, total station, developer, tanah kapling, pengukuran lahan

Abstract

Abstrak. Malino sebagai kawasan wisata unggulan di Kabupaten Gowa, Sulawesi Selatan, memiliki potensi ekonomi lokal melalui UMKM kuliner tradisional seperti teng-teng kacang dan wijen. Meski menjadi produk ikonik, UMKM masih menghadapi tantangan pada aspek kemasan yang sederhana dan kurang menarik, serta minimnya pemanfaatan media digital dan keterlibatan dalam promosi. Hal ini berdampak pada rendahnya daya saing produk di tengah persaingan pasar yang semakin berkembang. Penelitian ini bertujuan untuk memberikan edukasi kepada pelaku UMKM di Malino terkait inovasi kemasan dan strategi pemasaran digital. Metode pelaksanaan mencakup observasi lapangan, wawancara mendalam, sosialisasi, pelatihan desain kemasan, dan workshop pemasaran digital. Hasilnya menunjukkan bahwa intervensi melalui edukasi mampu meningkatkan pemahaman pelaku UMKM terhadap pentingnya kemasan yang menarik dan informatif, serta strategi promosi berbasis media sosial. Kegiatan ini tidak hanya memperkuat identitas produk, tetapi juga membuka akses pasar yang lebih luas. Oleh karena itu, edukasi pengemasan dan media promosi dapat menjadi solusi strategis dalam meningkatkan daya saing serta keberlanjutan usaha UMKM di kawasan wisata Malino. Kata Kunci: UMKM, kemasan produk, promosi digital

Abstract

This community engagement program aims to enhance the technical competencies of students in a vocational education institution through the application of Total Station technology for contour measurement. The initiative was designed to bridge the gap between classroom theory and modern field surveying practices by integrating structured training, intensive mentoring, and digital mapping tools. A total of 30 geomatics students participated in the program, engaging in instrument familiarization, field measurement exercises, and data processing using CAD-based mapping software. The training adopted an experiential learning model with a learning-by-doing approach, supported by digital modules and instructional video tutorials. Evaluation results show substantial improvements in student competencies: 85% of participants were able to operate the Total Station independently, 70% processed survey data digitally, and 80% produced contour maps of acceptable quality. The program also generated a digital learning module as a sustainable output. These findings demonstrate that integrating Total Station technology into vocational education effectively improves students’ understanding of topography, spatial data analysis skills, and industry-oriented work readiness.
