Abstract

The economic potential of mangroves can be a provider of economic resources, preserving the ecological environment and providing environmental services. Mangrove soil in Kuala Langsa is important to study as the potential for carbon sequestration in the form of biomass, the social potential of the community in supporting the development of efforts. The purpose of this study was to determine how much electricity was generated by the Kuala Langsa mangrove mud soil and how the effect of variations in electrode material on the electricity produced by the Langsa mangrove mud soil. The method used is to use a series of voltaic cells. The results of this study obtained data that mangrove mud soil can be used as alternative energy by using variations of Cu-Zn and Cu-Al electrode pairs with a mangrove mud mass of 350 ml, at Cu-Zn electrode pairs the largest electric power obtained is 0,8736 J/s. with the lamp on while the Cu-Al electrode pair obtained an electric power of 0,1794 J/s with the lamp not lit

Abstract

Indonesia is a country that has volcanoes stretching from west to east from Sumatra, Java to Sulawesi. Mount Arjuno-Welirang is a stratovolcano type volcano with an altitude of about 3,339 m (10,955) for Mount Arjuno while for Welirang it is about 3,156. Mount Arjuno-Welirang and its surroundings are composed by rocks sourced from Anjasmoro Volcano (Early Plistocene), Ringgit-Pundak-Butak Volcano (Middle Plistocene), Arjuno-Welirang Twin Volcanoes I and II (Late Plistocene), and Penanggungan Volcano. This research includes data processing and interpretation of the results of data processing.  This research was conducted using geophysical methods, namely the gravity method. The theoretical basis used is Newton's Law. Data in the form of gravity data that has been downloaded on the Land Gravity Data Website which is then processed using Surfer software, then the Magpick Software Upward Continuation process is carried out. After that, the slicing process is carried out on the residual anomaly, then the slicing results will be used to interpret using Grav2DC Software qualitatively based on the geological map as a reference. The interpretation results on the A-B and C-D tracks obtained 4 rock layers, namely volcanic breccia, lava, tuff breccia, and tuff rock. With an error value of 8.25% for incision A-B, and 3.63% for incision C-D.

Abstract

This research aims to determine (1) whether or not there are misconceptions of class X Riyadul Mubarok Integrated High School students regarding renewable energy application of the Certainty of Response Index (CRI) technique; (2) what sub-concepts are the most common misconceptions experienced by class X students at Riyadul Mubarok Integrated High School regarding renewable energy material using the CRI method. Using the purposive sampling technique, twenty students from class X made up the sample. The phenomena of misunderstandings regarding renewable energy, which contains three subconcepts the the energy conservation law, energy conversion, and the topic of this form of descriptive qualitative research is alternative energy. According to the study's findings, students' misconceptions on renewable energy fall into the low category 19.34%, whereas the sub-concept of energy conversion has the highest number of misconceptions 31.7%. With a value of 14.45%, the alternative energy sub-chapter has the lowest misperception category.The questions with the highest percentage of misconceptions 40% are found in items 4 and 13, whereas question number 9 has the lowest rate of misconceptions 0%. Overall, comprehension of the material on renewable energy is not very high, 25.34% of students understood the concept, compared to a higher number of 37.67% of students who did not

Abstract

This study explores the relationship between carbon dioxide (CO₂) concentration from paper combustion and temperature changes using a greenhouse effect simulation. Two desiccators were used: desiccator A with an LED lamp as an additional heat source, and desiccator B without an external heat source. The results showed that an increase in CO₂ in desiccator A significantly raised the temperature, demonstrating CO₂'s role in heat retention. However, in desiccator B, a temperature drop occurred due to the endothermic effects of paper combustion and water evaporation. These findings highlight the importance of external energy sources in manifesting the greenhouse effect and explain the complexity of the thermodynamic processes involved. This study contributes to a deeper understanding of CO₂-induced temperature changes and its relevance to global warming. The experiment can be used as an effective educational tool to introduce students to the greenhouse effect concept.

Abstract

This study aims to determine whether the influence of problem-based learning models can improve student learning outcomes in the main material of Newton's law in the even semester of class X of SMA Negeri 1 Percut Sei Tuan. This study is a quasi-experimental study. The population of the study was all students of class X of SMA Negeri 1 Percut Sei Tuan consisting of 10 classes, then sampling was carried out using random sampling techniques. The instrument used to determine student learning outcomes was a learning outcome test in the form of a multiple-choice test totaling 20 questions. The results of the study obtained an average pretest score of the experimental class of 34.58 and a control class of 32.77. After the pretest data was normal and the difference test was homogeneous, the values ​​of the two classes were obtained that both classes had the same initial abilities. Then different treatments were given, namely the experimental class with a problem-based learning model and the control class with a conventional model. The average posttest score of the experimental class was 81.66 and the control class was 65.69. After the normal and homogeneous posttest data were obtained, the difference test values ​​of the two classes showed that there were differences due to the influence of the problem-based learning model on student learning outcomes in the main material of Newton’s law in class X of SMA Negeri 1 Percut Sei Tuan.

Abstract

This research aims to develop a three-tier diagnostic test instrument to identify misconceptions in fluid physics among grade XI students at SMAN 2 Medan. Misconceptions are a persistent barrier in learning physics and require specific instruments for accurate identification. The developed instrument includes multiple-choice questions (first tier), reasoning options (second tier), and confidence levels (third tier) to assess students' conceptual understanding comprehensively. Using the 4D (Define, Design, Develop, Disseminate) development model, the instrument underwent validation by experts, small-scale, and large-scale trials. The results indicated that the diagnostic test instrument is valid and reliable, effectively identifying students' misconceptions in fluid concepts such as hydrostatic pressure, Archimedes' principle, Pascal's law, and Bernoulli's principle. This instrument not only aids teachers in recognizing areas that need instructional emphasis but also contributes to improving learning strategies. The findings revealed a significant portion of students experienced misconceptions, highlighting the need for targeted pedagogical interventions. This study contributes to physics education by offering a practical diagnostic tool to improve conceptual learning and reduce misconceptions.
