Groundwater serves as a primary resource for the community of Sidomulyo Timur, Marpoyan Damai District, Pekanbaru City, primarily for household and industrial needs. Increased domestic and industrial activities in this area have the potential to cause groundwater contamination through waste infiltration. This study aims to analyze the level of groundwater contamination by combining the Wenner C…
Physics as a science that studies natural phenomena requires an understanding of facts, concepts, principles, and theories obtained through the scientific process. However, physics learning is often centered on the teacher, so students tend to only memorize formulas without understanding their meaning which causes physics to be considered difficult. One approach that can overcome this problem i…
Ferroelectric materials are a special type of dielectric material in the form of thin films, widely applied in transducers, switches, sensors, capacitors, and memory devices due to their ease of modification and permanent properties. In this study, thin films of (0.4)BaTiO₃-(0.6)BaZr₀.₅Ti₀.₅O₃ (BT-BZT) were doped with pineapple peel extract and tantalum at concentrations of 0.5 wt%,…
Bacterial resistance to antibiotics has become a global challenge, prompting the search for more effective and environmentally friendly antibacterial alternatives. This study aims to synthesize and characterize zinc oxide (ZnO) nanoparticles using a biosynthesis method with green betel leaf (Piper betel L.) extract as a reducing and stabilizing agent. The synthesis process was carried out by mi…
In this study, ZnO nanoparticles were synthesized in an environmentally friendly manner at various pH levels (6, 8, 10, and 12) using fresh betel leaf extract. The effect of pH on optical properties was analyzed using a UV-Vis spectrophotometer. Meanwhile, structural and morphological properties were characterized using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). FTIR charac…
Optical fiber is a high-tech transmission medium with higher data transfer rates than conventional cables. This technology increases communication efficiency and channel capacity. Its advantages support the optimization of modern communication systems. Despite its advantages, fiber optic communication experiences bending loss interference where signal attenuation occurs due to changes in the st…
Optical fiber was chosen as a transmission medium because of its ability to transmit data with high power, high speed and low attenuation. Despite these advantages, optical fiber still faces challenges such as attenuation and dispersion which can reduce data transmission performance. This research examines the performance of fiber optic-based communication systems using Fiber Bragg Grating (FBG…
Many sensors show a nonlinear relationship between their input and output. Due to this nonlinearity, direct reading of the sensor across its sensing range is difficult. The NTC (Negative Temperature Coefficient) thermistor is a temperature sensor that exhibits nonlinear characteristics between resistance and temperature, in which its resistance decreases as the temperature increases. This resea…
IPTEK is an abbreviation of Science and Technology. As time goes by, science and technology are becoming more sophisticated and supporting the creation of new technologies. The era of industrial revolution 4.0 is an era where almost everything is controlled by technology, including in the world of education. The impact of the industrial revolution 4.0 era in the world of education is that there…

Perubahan zaman mendorong pentingnya peningkatan kualitas pendidikan untuk menghadapi berbagai tantangan. Salah satu faktor yang membuat kegiatan belajar mengajar tidak berjalan efektif yang mengakibatkan hasil belajar siswa tidak optimal adalah guru tidak memahami karakter…
Perkembangan zaman dan tuntutan yang kompleks di dunia global mendorong dunia pendidikan untuk terus beradaptasi dengan kemajuan teknologi. Pergeseran paradigma pembelajaran pada abad ke-21 menunjukkan perubahan yang signifikan, dimana peran guru sebagai pusat pembelajaran (teacher-centered learning) telah berubah menjadi peran peserta didik yang menjadi pusat pembelajaran (student-centered lea…
Education is said to be absolute because it cannot be separated from a person's life, both in individual life and in the nation and state. Education can also be a long process to achieve a general goal, and to achieve this goal, the process must be carried out in stages. Science learning will direct student-centeredness. This event will emphasize participants to be actively involved in the lear…
This research is motivated by various problems, especially in the cognitive learning outcomes of students who do not reach the KKM. In addition, this is due to low learning independence. These two things are the foundation for students to gain full knowledge so that they can improve other abilities. One solution to increase learning outcomes and student learning independence is to realize activ…
