Abstract

Utilising an excellent teaching tool is vital for students' education nowadays.  In contrast to the traditional teaching way, Technology-Embedded Solar Energy STEM (SESTEM) module was created as a modern teaching tool for physics subject. In order to develop and evaluate the students’ perception towards the complete SESTEM module, developmental research and technology acceptance model (TAM) were applied in this research study. 52 randomly selected diploma students from Sultan Idris Education University (UPSI) were involved as respondents in this work. After the development of the SESTEM module using the analysis, design, development, implementation and evaluation (ADDIE) model, the perceptions of students as respondents towards this module were evaluated based on the TAM via questionnaire. Based on the responses from the respondents, the majority of the respondents demonstrated positive attitudes and behaviour intention, as well as agreed that the SESTEM module was useful as a teaching tool. Besides, the respondents showed a positive technological acceptance towards SESTEM module. The respondents' acceptance was contingent on the employment of technology for educational purposes in the future. Consequently, SESTEM module could be utilised by educators as a contemporary tool for enhancing student learning for future benefits.

Abstract

Low student learning outcomes are due to teacher-centered learning and lack of use of digital  materials. One way to solve this problem is the use of digital educational resources for STEM (science, technology, engineering, and math) topics. This study's objective was to ascertain the impact of her STEM-based digital material for light waves on student learning outcomes in a physics class. This method of research  is the scientific method, that is, experimental research. The study design used is a straightforward experimental strategy (post-test only control strategy). The XI IPA class served as the study's entire population, and the samples used were from the XI IPA 3 control class and the XI IPA 4 experimental class. Data collection means use end-of-learning tests or post-tests. Data processors were performed using the IBM SPSS program version 29.0 with normality tests, homogeneity tests, and hypothesis tests (t-tests). Based on the outcomes of our research, we discovered that the obtained data are normally distributed with a level of 0.182 ≥ 0.05 for the control class and 0.073 ≥ 0.05 for the experimental class. For the homogeneity test, the levels are 0.073 ≥ 0.05, so  the classes are homogeneous. On the other hand, for hypothesis tests or t-tests, the obtained sig (two-tailed) post-test is <0.001. This value is less than 0.005 and is based on the rejection criteria for Ho. The result of the pre-test t-test analysis  is 0.164, which means that this value is greater than 0.05, so  Ho is accepted. From this, we can conclude that his STEM-based digital teaching materials on light waves have an impact on students' learning outcomes in physics classes.

Abstract

This is descriptive research. A descriptive analysis method is a method of explaining symptoms using various variables from the study that are related to one another. This study investigated the shape, size, and composition of TiO2 and ZnO nanoparticles used in sunscreens to reflect and scatter ultraviolet radiation. The study focuses on the effects of these inorganic substances on ultraviolet and visible light absorption and reflection. XRF, UV-Vis spectroscopy, and XRD were used to analyze TiO2 and ZnO particles taken from 50-SPF sunscreen. The concentrations of TiO2 and ZnO in the product were 29.625% and 0.045%, respectively. The sizes of TiO2 and ZnO are obtained using a systematic equation, with the TiO2-particle nanosize of 26.31 nm in the form of TiO2-anorthic respectively. Based on the results obtained, the greater the TiO2 and ZnO content used, the greater the UV absorbance produced. Maximum absorbance indicates that electrons cannot absorb energy at that wavelength, so the energy is just passed through. Meanwhile, the greater the TiO2 and ZnO content used, the less reflectance there is in the UV region, and the visible light produced will also increase. Meanwhile, the greater the TiO2 and ZnO content used, the greater the reflectance in the UV region and the visible light produced

Abstract

Compressive strength testing is carried out on mortar made from a mixture of sand, cement and water. Mortar is one of the construction materials in building structures that has the main function as a material for construction parts. The compressive strength test is useful for measuring and knowing the strength of objects against compressive forces. The method used in this research is rock magnetism to determine the abundance of magnetic minerals and compressive strength testing to determine the relationship of compressive strength results to the magnetic minera content of Nagari Aia Angek volcanic sand. Volcanic sand is measured using a Bartington Susceptibility Meter Type MS2B with 3 forms of mineral separation treatment, namely Magnetic Mineral Reduction (PMM) with a value of χlf  505,99 x10 m-83 /kg, χfd (%) 2.72%, Additional Magnetic Minerals (TMM) with a value of χlf 1026.72 x10 m-83 /kg, χfd (%) 2.14%, and No Treatment (TP) with a value of χlf 853.98 x10 m-83 /kg, χlf (%) 2.16. The results of testing the compressive strength of mortar using Compression Testing Mechine on 3 volcanic sand treatments were obtained (PMM) with a value of 169.14 kg/cm2, (TMM) with a value of 147.11 kg/cm2, and (TP) with a value of 141.81 kg/cm2. The magnetic properties of volcanic sand samples are antiferrimagnetic and have superparamagnetic mixed grains and coarse grains. There is a relationship between the compressive strength value of mortar and the concentration of magnetic minerals, the higher the compressive strength value, the higher the χfd (%) value obtained

Abstract

Abtract- Lake Maninjau is a volcanic caldera formed by a volcanic eruption located in West Sumatra. This volcanic eruption threw pyroclastic materials, one of which is pumice, as far as ± 75 km from the center of the eruption. This study aims to determine density and magnetic susceptibility characteristics of pumice from maninjau caldera-forming eruptions, indonesia. The method used is the rock-magnetic method. It is used to measure magnetic susceptibility based on the distribution of volcanic material. The samples were selected from 3 different locations around Mount Maninjau with distances varying between ±12-32 km. A Bartington Magnetic Susceptibility Metre Type B (MS2B) instrument was utilised to determine the susceptibility of rocks and X-ray fluorescence (XRF) to identify rock element levels. The results of the data analysis obtained have magnetic density and susceptibility values in the NGS (Ngarai Sianok) area, which ranged from 0.67-1.77×103 kg/m3 and 4.4-826×10-8m3/kg, the LBS (Lubuk Basung) area which ranged of 0.74-1.34×103 kg/m3 and 6.6-625.4×10-8m3/kg, and the PRM (Pariaman) area, which ranged from 0.68-3.63×103 kg/m3 and 8-359×10-8m3/kg. The results showed that when sampling closer to Mount Maninjau, the pumice is characterized by dense, fresh, but very small pore size and dominated by slightly greyish white pumice with few white crystals on its surface. Therefore, the location of the pumice from Mount Maninjau has a significant influence on its characteristics, including density, magnetic susceptibility, and iron (Fe) and titanium (Ti) content.
