Abstract

This article reports on a community service program to implement a waterwheel-based micro-hydro power system by constructing a civil water intake in Nagari Kamang Hilia, Agam Regency, West Sumatra. The program aimed to provide renewable electricity for rice milling and community street lighting, while strengthening local capacity for operations and maintenance. The implementation consisted of stakeholder coordination, field surveys, drone-based mapping, preparation of Detailed Engineering Design, civil intake construction, electrical integration, commissioning, and community training. The constructed components included an intake structure, a guide channel, a sluice gate, a trash rack, inlet and outlet channels, and a waterwheel chamber. These components were designed to regulate water flow, minimize disturbance from sediment and debris, and support stable waterwheel operation under low-head conditions. Field measurements indicated an average flow velocity of approximately 2 m/s, supporting an initial system capacity of about 5 kW. The system provides renewable electricity for productive use and street lighting, reducing dependence on costly diesel fuel and improving local energy resilience. The training activities also improved community knowledge of intake cleaning, sediment control, waterwheel inspection, and basic electrical safety. The program demonstrates that integrating civil engineering infrastructure, renewable energy technologies, and community participation can serve as a practical model for sustainable rural development.

Abstract

Pedestrians are the most vulnerable road users. If involved in an accident, the risk of fatality they face is greater than that of other road users (Shinar, 2007). This study aims to analyze the level of safety for pedestrians based on the level of risk expressed by the Pedestrian Risk Index (PRI). The case study was conducted on pedestrian students at SMAN 1 Gunung Talang. The data in this study are traffic conflict data obtained from analysis of field observations. The data required in calculating the Pedestrian Risk Index (PRI) were obtained from field observations. The observations were conducted over two days, namely Monday and Tuesday, where the morning survey was conducted from 06.30 - 07.30 when students entered school and in the afternoon from 15.00 - 16.00 when students returned from school. The data were further analyzed to obtain the Pedestrian Risk Index (PRI) value. The results of the data analysis show that there are differences in PRI values ​​based on the day and time of the crossing, namely crossings carried out in the morning have a higher average PRI value of 124.91 than crossings in the afternoon with an average PRI value of 61.55. Based on this study, it can be concluded that crossings carried out in the afternoon have a higher level of safety compared to crossings carried out in the morning.

Abstract

Traffic safety remains a significant issue among adolescents in Indonesia. Senior high school students represent a particularly susceptible demographic. This community service initiative aimed to enhance students' understanding of road safety at SMAN 1 Harau via an interactive card game called Road Smart Card. The program was executed with a one-group pretest-posttest design involving 30 students. The Traffic Smart Card featured depictions of traffic signs, authentic traffic scenarios, and educational inquiries to promote dialogue and contemplation. The results indicated a notable enhancement in students' knowledge, with a posttest mean score of 90.50 compared to a pretest mean score of 71.17, reflecting a 27.17% gain. The mean N-Gain score is 0.68, categorizing it as high and affirming the efficacy of the learning medium. Fifty percent of students achieved a high gain classification, while the remaining fifty percent fell into a medium group, with no students categorized as low. Over 90% of the students actively participated in group discussions and game activities, fostering an engaging and enjoyable learning environment. The therapy also resulted in emotional and behavioral changes in addition to cognitive improvements. The school committed to including media in standard educational practices, the School Safety Patrol extracurricular program, and OSIS activities. The program effectively enhanced understanding and road safety culture among young students in a pertinent and sustainable manner.

Abstract

Large building projects require a construction sequence that integrates technical dependencies, site access, material flow, and crew allocation. This study analysed the implementation of structural work sequencing and a zoning system in the Summarecon Mall Bandung Phase 2 project. A descriptive case-study approach was used. Data were obtained from project documents, shop drawings, field observations, and photographic documentation produced during the 2023 construction period. The analysis identified the logical dependencies between work packages and examined how six work zones were released. The structural sequence consisted of pile driving, pile-head cutting, excavation and backfilling, soil compaction, pile-cap and tie-beam construction, column works, and beam-and-slab works. Zones 1 and 5 were started first because they did not interfere with the main access and equipment manoeuvring areas. Zones 2 and 3 followed when the first zones reached approximately 30% progress. Zones 4 and 6 were completed last because they functioned as the principal access and logistics corridors. The zoning strategy enabled overlapping activities while maintaining access, but its effectiveness depended on labour competence, material delivery, equipment availability, approvals, financing, and site coordination. The study concluded that explicit access constraints and progress-based release rules should be included in structural work-sequencing plans.

Abstract

Changes in land cover within industrial areas have the potential to reduce soil infiltration capacity and increase the risk of surface runoff and flooding. This study aims to analyze and compare infiltration capacities across various land cover types within the industrial area of PT Semen Padang. Infiltration measurements were conducted using the double-ring infiltrometer method on several land cover types, namely greenbelt areas, open land, and developed areas. The data obtained were analyzed using the Horton model approach to determine initial and constant infiltration rates. The results indicate that greenbelt areas exhibit the highest infiltration capacity, with an average constant infiltration rate of 183.3 mm/h, followed by open land at 74 mm/h, while built-up areas showed the lowest rate at 35.9 mm/h. These differences are influenced by soil density, organic matter content, and vegetation root activity. These findings indicate that an increase in built-up surface area significantly reduces the soil’s ability to infiltrate water, thereby potentially increasing surface runoff. This study recommends the implementation of green infrastructure and the conservation of vegetated land to support sustainable stormwater management in industrial areas.

Abstract

This community service program, conducted by Universitas Negeri Padang in Nagari Kamang Hilia, Agam Regency, focused on the planning, construction, and utilization of a micro-hydro power plant to support local agricultural activities. The program began with coordination with the Nagari government and community to identify challenges and beneficiaries, followed by technical surveys including water discharge mapping, hydraulic head measurement, and land suitability analysis using GIS and UAV-based mapping. Based on these data, detailed engineering designs were prepared for the turbulence-based intake structure, inlet channel, and powerhouse. The project then advanced to the construction of civil works, the installation of turbines, generators, and control panels, and the testing of the operational system. With an installed capacity of up to 5 kW, the plant now provides renewable electricity for agricultural use and street lighting, helping reduce dependence on costly diesel engines. Training and counseling were also delivered to ensure that the community can operate and maintain the system independently. The program demonstrates how micro-hydro technology can be effectively applied to foster rural electrification, empower local farmers, and contribute to sustainable development goals.

Abstract

Overburden removal is a critical determinant of production continuity in open-pit coal mining, yet inefficiencies in equipment utilization frequently hinder the achievement of production targets. At PT Kurnia Alam Investama, a monthly overburden stripping target of 150,000 BCM for February 2025 was established, to be achieved using two equipment fleets with a planned capacity of 75,000 BCM/month per fleet. However, preliminary observations indicate a discrepancy between planned and actual production, highlighting the need for a systematic evaluation of equipment performance and fleet compatibility. This study aims to assess the productivity and operational synchronization of a CAT 330 GC excavator and Mitsubishi Fuso 220 PS 6x4 HD dump trucks through cycle time analysis, productivity estimation, and match factor evaluation. The results show that actual productivity reached 67,150.72 BCM/month for the excavator and 52,407.4 BCM/month for the hauling units, both below the production target. The average cycle times were recorded at 0.343 minutes for the excavator and 5.39 minutes for the dump trucks. The calculated match factor (MF < 1) indicates an imbalance in the loading–hauling system, resulting in excavator idle time due to insufficient truck availability. The findings reveal that equipment condition and operator performance are the dominant factors affecting productivity losses. This study emphasizes the importance of fleet balancing, cycle time optimization, and operational improvements to enhance equipment utilization and achieve production targets efficiently.

Abstract

In the era of Industry 4.0, UAV (Unmanned Aerial Vehicles) have become key technologies used widely, not only for military operations but also for mapping, monitoring volcanic activity, and producing documentary videos. Two tools advancing rapidly and highly relevant to vocational education are drones and theodolites. Their adoption in vocational schools still lags behind, especially in rural areas, so Geomatics teachers need capacity building to update Land Surveying course materials and transfer practical skills to students. This science and technology outreach program aims to equip teachers at SMK Negeri 1 Lubuk Sikaping with foundational knowledge and skills for operating drones and theodolites, along with data analysis for aerial mapping. The training is arranged sequentially, beginning with an introduction to platforms, sensors, operating principles, and safety; continuing with field practice covering mission planning, control point acquisition, and calibration procedures; and concluding with data and video processing for construction project needs, including georeferencing, orthomosaic generation, elevation modeling, and extracting relevant measurements. The targeted outputs include scientific publications in ISSN journals or national proceedings, an activity video of about 3 to 4 minutes, and coverage in print or online media. Through this program, the gap in technology and information mastery is expected to narrow, the curriculum to become more current, and teachers’ pedagogical and technical competencies to improve, particularly in structural and mapping applications. Graduates under their guidance will be better prepared to enter industry with strong spatial literacy, careful data acquisition, and a solid safety culture.
