The fiber tissue hole area in Dye-Sensitized Solar Cells with an Infusion-Based Continuous Electrolyte System has been studied. Fiber tissue can be used as an electrolyte storage medium in DSSCs because it can withstand evaporation, thus stabilizing the electrolyte availability in the active area. Meanwhile, the infusion-based continuous electrolyte system functions as an electrolyte supplier t…
The ability to deliver effective presentations performance remains a major challenge for many EFL students. However, many students still depend heavily on scripts during presentations. Therefore, this study aimed to investigate the role of concept mastery on students’ English presentation performance by exploring students’ perceptions, their implementation of concept mastery during presenta…
Research on rice analog made from purple sweet potato flour and glucomannan still faces limitations in producing characteristics that resemble those of conventional rice, making it necessary to optimize the proportions of the ingredients. This study aims to determine the effect of varying formulations of purple sweet potato flour and glucomannan on the physical, chemical, and sensory characteri…
Limestone blasting activities at PT Semen Padang generally produced fragmentation that tended to fall within the fine to medium size category. The dominance of excessively fine fragments may increase dust generation and fine material loss, while also indicating inefficient utilization of blasting energy. This condition was influenced by the actual blasting geometry and rock mass conditions in t…
Limestone hauling activities at PT Semen Padang are affected by the haul road geometry from Front B to Limestone Crusher VI. This study aims to analyze haul road geometry, calculate cycle time and hauling equipment productivity, and provide improvement recommendations to increase the production achievement of Front B toward the estimated monthly target. The parameters analyzed using ArcMap 10.8…
