The research was carried out in September-December 2025 at the Biology Education Lab, UNSRI. The research used qualitative descriptive methods. Stem anatomy observations included epidermal layers, cell shape and size; trichome type; collenchyma location, type and …
Iron (Fe) metal is often found in well water and at high concentrations can degrade water quality. This study synthesized a Biochar/MnFe₂O₄/Ag₃PO₄ composite, evaluated its characteristics, Fe adsorption capacity, and applied it to well water and antibacterial tests. Biochar was synthesized through pyrolysis of rice husk, MnFe₂O₄ was modified through coprecipitation, and followed by …
Background: Industrial noise exposure is a major occupational risk factor associated with noise-induced hearing loss (NIHL) and vestibular dysfunction. Continuous exposure to sound levels exceeding 85 dB is known to impair auditory and balance function. This study aimed to examine the correlation between noise intensity and duration of exposure with hearing impairment and balance impairment amo…
This study aims to implement Deep Learning among fourth-grade students at SD Negeri 4 Palembang through a science literacy-based Problem-Based Learning (PBL) model. The model integrates materials on the seasons in Indonesia and their effects on daily life, with a focus on development procedures, validity, and practicality of the learning model. The research employs a development study using the…
Ketergantungan masyarakat pedesaan terhadap sumber air alami masih sangat mencolok. Air Gambut di daerah pasang surut, misalnya terpaksa masih dimanfaatkan oleh masyarakat setempat sebagai air minum meskipun kondisinya tidak memenuhi persyaratan kesehatan secara fisik maupun kimia. Kondisi seperti ini mendorong perlunya teknologi pengolahan air yang sederhana, murah dan mudah diterapkan sehingg…
This research aims to evaluate students' critical thinking skills before and after the learning process and to determine the effect of integrating instructional video media into the STEAM approach for sixth-grade elementary school students. A quantitative approach was employed, specifically a quasi-experimental design featuring a non-equivalent control group. The study involved two groups: an e…
The increasing use of online games among elementary school students has the potential to influence their social behavior. This condition gives rise to various social behavioral issues, such as the emergence of aggressive attitudes when emotions are not well controlled and a decrease in direct interaction with others. This study aims to explore the social behavior of elementary school students w…

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…

Perkembangan distribusi musik digital menimbulkan permasalahan baru dalam perlindungan hak cipta, salah satunya klaim sepihak atas karya lagu oleh aggregator musik digital tanpa persetujuan pencipta. Tindakan tersebut berpotensi merugikan pencipta lagu dari segi hak moral dan hak ekonomi. Penelitian ini bertujuan untuk menganalisis bentuk perlindungan hukum terhadap pencipta lagu serta mekanism…
Cassava crackers (Manihot esculenta) are traditional foods made from cassava that require a drying process before consumption. Conventional drying methods still rely on direct sunlight, making the process less effective due to weather conditions. Therefore, an automatic rack-type dryer with an electric heater was used to improve the efficiency and stability of the drying process. This study aim…
