Abstract

Perlintasan sebidang kereta api merupakan salah satu titik konflik antara lalu lintas jalan dan perjalanan kereta api yang memiliki risiko keselamatan tinggi, khususnya bagi pengendara sepeda motor. Namun, penelitian yang secara khusus menganalisis pengaruh kondisi teknis Concrete Level Crossing (CLC) dan perilaku pengendara terhadap risiko keselamatan pengendara sepeda motor masih terbatas. Penelitian ini bertujuan untuk menganalisis pengaruh kondisi teknis CLC dan perilaku pengendara terhadap risiko keselamatan pengendara sepeda motor. Penelitian menggunakan pendekatan kuantitatif dengan metode survei pada dua perlintasan sebidang tipe CLC di Kota Padang yang melibatkan 400 pengendara sepeda motor sebagai responden. Data dikumpulkan melalui kuesioner dan observasi lapangan, kemudian dianalisis menggunakan regresi linear berganda. Hasil penelitian menunjukkan bahwa kondisi teknis CLC dan perilaku pengendara berpengaruh positif dan signifikan terhadap risiko keselamatan pengendara sepeda motor pada kedua lokasi penelitian. Nilai koefisien determinasi (R²) sebesar 0,463 pada Jalan Prof. Dr. Hamka, Kota Padang dan 0,497 pada Jalan Alai, Kota Padang menunjukkan bahwa model mampu menjelaskan 46,3% dan 49,7% variasi risiko keselamatan. Variabel kondisi teknis CLC merupakan faktor yang lebih dominan dibandingkan perilaku pengendara, yang ditunjukkan oleh nilai koefisien beta sebesar 0,521 pada Jalan Prof. Dr. Hamka, Kota Padang dan 0,586 pada Jalan Alai, Kota Padang.

Abstract

Purpose: This study evaluates the implementation of an integrated solar-powered rainwater harvesting, well water, and treatment system at SMAN 12 Padang as an alternative source of non-potable clean water and a green-school technology. Design/methods/approach: The intervention integrated rooftop rainwater collection, well water, staged filtration, photovoltaic power, and IoT-based monitoring. Water quality was evaluated before and after filtration using temperature, pH, total dissolved solids (TDS), turbidity, iron (Fe), and zinc (Zn). System implementation also included a 600 Wp photovoltaic array, water filtration units, and real-time monitoring. Findings/results: Before treatment, two source samples showed acidic pH (5.60 and 5.19), TDS of 408 and 320 ppm, and high turbidity of 209 and 281 NTU. After filtration, the measured water quality improved to 28 °C, pH 6.9, TDS 198 ppm, turbidity 4 NTU, Fe 0.110 ppm, and Zn below the limit of detection. The IoT dashboard also recorded post-treatment values of 25.1 °C, pH 6.14, and TDS 182 ppm during system operation. Conclusions: The integrated system substantially improved the measured physicochemical quality of the available water and demonstrates the feasibility of combining rainwater and well water utilization, filtration, solar energy, and digital monitoring for sustainable school water management. Further routine microbiological testing and long-term performance monitoring are required before making drinking-water claims.
