Abstract

The rising demand for concrete in the building sector has resulted in the exhaustion of natural sand and freshwater supplies, leading to the pursuit of sustainable substitutes. Coastal areas have plentiful ferronickel slag (SL) and seawater (SW), which can be used to manufacture concrete. Nevertheless, the possibility of corrosion to steel reinforcement raises concerns that require further research. This investigation examines the mechanical and durability performance of concrete that incorporates SL as a partial replacement for fine aggregate and SW as a mixing component. The objective is to optimize SL content to improve compressive strength, resistance to chloride ions, and overall durability. Experimental results show that replacing 25% of the aggregate with SL yields the best combination of workability, strength, and durability, significantly enhancing compressive strength, decreasing porosity, and lessening chloride ion penetration, as evidenced by the Rapid Chloride Penetration Test (RCPT). Although seawater promotes early-age hydration and strength development, its extended use slightly diminishes compressive strength due to salt-induced micro-cracking. However, SL counters these effects, making SW–SL mixture a feasible and sustainable option for concrete production in coastal and resource-limited areas. A significant relationship between RCPT and compressive strength underscores the important role of SL in densifying the matrix and improving impermeability. The concrete mixture with 25% SL exhibits the lowest abrasion weight loss at 28 and 120 days, showing improved durability. This study highlights the potential of using SL and seawater to create eco-friendly and high-performance concrete for harsh environments.

Abstract

Penelitian ini dilatarbelakangi oleh penurunan kinerja fisik saluran pembawa dan ketimpangan pembagian air pada jaringan irigasi semi-teknis di Kota Padang Panjang, khususnya Jaringan Irigasi Batang Pekah, Kelurahan Ekor Lubuk. Tujuan penelitian adalah mengevaluasi efisiensi penyaluran air dan pemerataan distribusi suplai irigasi pada lahan layanan 10,4 hektar. Penelitian menggunakan pendekatan kuantitatif deskriptif melalui pengukuran lapangan pada saluran sekunder sepanjang 633,7 m yang dibagi menjadi enam titik pengamatan, yaitu BBP 0 sampai BBP 5. Data dikumpulkan melalui observasi kondisi fisik saluran, pengukuran dimensi penampang, pengukuran kecepatan aliran dengan current meter, serta perhitungan kebutuhan air berbasis curah hujan efektif dan komponen kebutuhan air tanaman. Hasil penelitian menunjukkan bahwa efisiensi total penyaluran hanya mencapai 62,37%, sehingga berada pada kategori kurang karena masih di bawah standar minimum 70%. Kehilangan air sebesar 37,63% terutama dipengaruhi oleh rembesan, kebocoran dinding beton, sedimentasi, serta pengaturan lubang sadap yang belum terstandar. Rata-rata Relative Water Supply sebesar 3,71 menunjukkan ketersediaan air secara kuantitatif masih surplus, tetapi nilai Koefisien Variasi sebesar 0,45 menunjukkan distribusi antar titik belum merata. Penelitian ini merekomendasikan rehabilitasi saluran, standardisasi bukaan sadap, dan pengaturan giliran air untuk meningkatkan efisiensi serta keadilan distribusi air irigasi.

Abstract

The Batanghari River, one of the largest rivers in Sumatra, Indonesia, serves as a vital transportation corridor and supports domestic, agricultural, and socio-economic activities. Water quality in the middle reaches of the river is associated with increasing anthropogenic pressures, including settlements, agriculture, sand and gravel mining, and domestic waste disposal. This study models the spatial distribution of water pollution parameters in the Batanghari River, Indonesia, using the Inverse Distance Weighting (IDW) method. The river, which serves as the study site, is 2.5 km long, and sampling was conducted at 16 points in Terusan Village, Maro Sebo Ilir District, Batang Hari Regency. The parameters analysed were pH, Total Suspended Solids (TSS), and Chemical Oxygen Demand (COD). pH measurements were conducted in situ, while TSS and COD were analysed in the laboratory. The measured values were evaluated using the Indonesian Class II river water quality specifications in accordance with Government Regulation No. 22/2021. Spatial distribution modelling was performed using the Inverse Distance Weighting (IDW) interpolation method in ArcGIS 10.8, with model performance evaluated via cross-validation using Root Mean Squared Error (RMSE). The results showed that pH values ranged from 6.76 to 6.91 and were within the class II standard limits. Total Suspended Solids (TSS) ranged between 230.12 and 313.93 mg/L, and Chemical Oxygen Demand (COD) ranged between 35.44 and 93.92 mg/L, exceeding the permitted limits. Areas with higher pollution concentrations were associated with settlements and mining activities, as indicated by the spatial distribution map. These findings suggest that IDW can be applied to the spatial representation of water quality and its improvement as an indicator for pollution control and river management.

Abstract

The global push for sustainable development has intensified the need to improve energy efficiency in higher education buildings, particularly in hot–humid tropical climates where cooling demand dominates electricity use. This study examines how occupant perceptions, environmental attitudes, and energy-related behaviors relate to measured building energy performance in a tropical university building, using a convergent parallel mixed-methods design. An ASHRAE Level 1–based energy audit (aligned with Indonesia’s MEMR Regulation No. 13/2012) profiled electricity consumption by end-use systems and was complemented by a 38-item questionnaire and semi-structured interviews with students, lecturers, and administrative staff. The audit estimated total annual electricity consumption of 366,897.7 kWh/year, corresponding to an average Energy Use Intensity (EUI) of 17.34 kWh/m²/month, and associated emissions of 285,108.85 kgCO₂eq. Cooling/HVAC accounted for the largest share of electricity use (≈55%), followed by plug loads/equipment and lighting. Survey results indicated generally high pro-environmental attitudes; however, quantitative associations between aggregated floor-level perceptions/behaviors and electricity use were exploratory, given the limited number of analytic units (four floors/zones). Still, floor-level correlations consistently suggested negative relationships between behavioral variables and energy consumption, with expectations toward green-energy practices showing a particularly strong inverse association (r = –0.968). Qualitative findings highlighted practical operational and behavioral drivers such as temperature setpoints, schedule discipline, and equipment shutdown practices, pointing to actionable opportunities for demand reduction. Overall, the study contributes an integrated audit–behavior perspective to support occupant-centered interventions, green-campus policy alignment, and sustainability-oriented learning activities for long-term low-carbon campus development in hot–humid contexts.

Abstract

Floods are disasters that disrupt human life caused by human and natural factors. Natural conditions that affect flooding in West Sumatra are rainfall patterns in water areas, sea surface temperature patterns, and whirlpool patterns in the Indian Ocean. Batang Lengayang is a river that is prone to flooding. Floods in the Batang Lengayang river occur every year, especially during the rainy season. According to the Central Statistics Agency of Pesisir Selatan Regency, in Lengayang District, floods were recorded 5 times throughout 2020, 8 times in 2021, and 10 times in 2022. Meanwhile, in 2024, there was also a flash flood on March 7 which was caused by very high rainfall intensity and on a long time scale. This study aims to determine the flood discharge of the Batang Lengayang river with a return period of 50 and 100 years. Furthermore, this study also aims to model the Batang Lengayang river flood using HEC RAS. And to determine the area of ​​flood inundation of the Batang Lengayang river for a return period of 50 and 100 years. The results of the study showed that the 50-year return period produced a maximum flood discharge of 399 m³/second and the 100-year return period produced a maximum flood discharge of 444.46 m³/second. The modeling results showed that the flood area increased with the addition of the return period. The flood area obtained was 376 ha or 3.7 km² for the 50-year return period and 412 ha or 4.12 km² for the 100-year return period.

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.
