Abstract

The goal of the study was to see how much of an impact online learning and learning motivation had on student achievement in the Building Engineering Education Study Program at the Indonesian Education University during the covid-19 pandemic. Learning achievement is evidence of someone's success after going through the learning process. This study employs a quantitative approach and employs a descriptive static research method survey. The study used 38 students from the 2018 Building Engineering Education study program as a sample. A questionnaire was used to collect data for the study, as well as documentation in the form of the 5th semester student achievement index value. According to the study's findings, (1) the average online learning score of 3.74 falls into the high interpretation category, (2) the average learning motivation score of 3.49 falls into the high interpretation category, (3) The average learning achievement score of 3.57 falls into the category of very good interpretation. With an coefficient determination of 0.044 or 4.4 percent, there is no significant effect of online learning and learning motivation on learning achievement.

Abstract

This study investigated a slope with tropical residual soil, utilizing SEEP/W and SLOPE/W modules within the Geostudio finite element analysis software. The research focused on examining changes in slope stability under various rainfall patterns and soil parameters. Subsequently, curves illustrating the variation of slope’s factor of safety over rainfall duration were obtained. The result indicate that the advance rainfall pattern has a more significant impact on slope stability compared to the delayed, uniform and peak patterns. Under different rainfall pattern, continuous rain consistently leads to gradual decrease in slope stability. An increase in rainfall directly causes a rise in pore water pressure and a reduction in the factor of safety. Steeper slopes exhibit a more extreme decrease in the factor of safety. The advanced pattern result in a rapid pore water pressure response and a drastic drop in the factor of safety in a short time.

Abstract

Waduk Cijurey merupakan salah satu infrastruktur sumber daya air yang berfungsi untuk memenuhi kebutuhan air irigasi dan air baku. Variasi debit inflow akibat kondisi hidrologi yang berbeda menyebabkan perlunya evaluasi pola operasi waduk agar pemanfaatan air tetap optimal. Penelitian ini bertujuan untuk mensimulasikan pola operasi Waduk Cijurey menggunakan perangkat lunak HEC-ResSim pada kondisi tahun basah, tahun normal, dan tahun kering. Data yang digunakan meliputi data teknis waduk, hubungan elevasi–luas–volume, debit inflow, serta kebutuhan air sebagai debit outflow. Simulasi dilakukan dengan membangun model waduk melalui penyusunan watershed, reservoir network, karakteristik tampungan, serta penerapan rule curve sebagai dasar pengoperasian waduk. Hasil simulasi menunjukkan bahwa pada kondisi tahun basah volume tampungan meningkat hingga mendekati kapasitas efektif sehingga terjadi limpasan (spillout) pada beberapa periode, sedangkan seluruh kebutuhan air tetap dapat dipenuhi. Pada kondisi tahun normal operasi waduk berlangsung stabil dengan keseimbangan antara debit inflow dan debit outflow sehingga elevasi waduk tetap berada pada zona operasi. Pada kondisi tahun kering terjadi penurunan volume tampungan akibat debit inflow yang lebih kecil dibandingkan kebutuhan air, namun pengoperasian berdasarkan rule curve masih mampu menjaga waduk berada di atas batas tampungan minimum. Hasil penelitian menunjukkan bahwa HEC-ResSim mampu digunakan sebagai alat evaluasi pola operasi Waduk Cijurey untuk mendukung pengelolaan sumber daya air yang lebih efektif.
