Abstract

This development research aims to develop an e-module based on the Self-Organized Learning Environment (SOLE) model assisted by Artificial Intelligence (AI) on kinematics material. The research and development method uses the ADDIE (Analysis, Design, Development, Implementation, and Evaluation) approach created by Robert and Maribe Brach. This model includes the following stages: 1) Analysis, 2) Design, 3) Development, 4) Implementation, 5) Evaluation. The subjects of this research were students from two schools, and the data collection instruments were questionnaires provided to expert validators and students. The data generated is qualitative and analyzed using assessment criteria guidelines to determine the quality of the product. The results of this research produced teaching materials and determined the quality of the developed product: 86% from material experts (categorized as highly feasible), 95% from media experts (categorized as highly feasible), 87% from educators, and 93% from students in small-scale trials, with 87% in large-scale trials, all categorized as very attractive. Based on these results, it can be concluded that the E-module based on the Self-Organized Learning Environment (SOLE) model assisted by Artificial Intelligence (AI) for kinematics material is highly feasible and attractive for use in high school physics learning for 11th-grade students.

Abstract

Lampung is one of the provinces in Indonesia which has quite high volcanic potential. This province has four active volcanoes, namely Mount Krakatau, Mount Anak Krakatau, Mount Sebesi, and Mount Rajabasa. These volcanoes have the potential to cause natural disasters, such as eruptions, earthquakes and tsunamis. This research aims to assess the potential of the Lampung volcano and its impact opportunities in terms of earthquake intensity and maximum ground acceleration. This research uses literature study and data analysis methods. The results of the research show that the intensity of earthquakes and maximum ground acceleration can influence the potential for natural disasters caused by volcanoes. High earthquake intensity can trigger volcanic eruptions, while high maximum ground acceleration can trigger tsunamis. This research provides recommendations for increasing community preparedness for natural disasters caused by volcanoes in Lampung. The government needs to socialize and educate the public about the potential dangers of volcanoes and ways to reduce disaster risks.

Abstract

Climate change driven by rising air temperature and humidity significantly impacts agricultural ecosystems' rainfall patterns and chemical and biochemical processes. This study aims to analyze the relationship between temperature, air humidity, and rainfall and their effects on chemical and biochemical transformations in agricultural and environmental systems in Lampung. This research employs a descriptive quantitative and qualitative approach. Primary data were collected through field observations, soil chemical testing, and public health surveys. Secondary data regarding temperature, humidity, and rainfall were obtained from BMKG. Surveys were conducted using structured questionnaires with purposive sampling techniques targeting affected communities. Data were analyzed using descriptive statistics and linear regression to examine relationships between variables, while chemical analysis measured changes in pH, nutrients, and greenhouse gas emissions. Data processing was performed using SPSS and Excel, and triangulation was conducted to ensure accuracy. The findings indicate that increases in temperature and humidity correlate with a 15% rise in annual rainfall over the last decade. The primary observed effects include increased soil acidity (pH decrease by 0.5-1.0 units), a nitrogen level reduction of up to 20%, and increased greenhouse gas emissions such as CH4 and CO2. Additionally, higher rainfall contributes to increased soil erosion and water pollution. In the health sector, surveys indicate a rise in waterborne diseases (diarrhea, cholera) and respiratory disorders. In conclusion, changes in temperature and humidity have complex effects on agriculture, the environment, and public health, necessitating adaptation and mitigation strategies to reduce their negative impacts.

Abstract

Conventional plastics significantly contribute to environmental pollution due to their non-biodegradable nature. Eco-friendly alternatives such as biodegradable materials are being developed to mitigate these negative impacts. This study employs a mixed-method approach with three main phases: (1) exploration and characterization of biodegradable materials based on polylactic acid (PLA) and corn starch; (2) environmental impact analysis using Life Cycle Assessment (LCA) to evaluate carbon footprint and energy consumption; and (3) consumer preference surveys through questionnaires and interviews in Bandar Lampung. The results indicate that biodegradable materials exhibit higher biodegradability and lower environmental impact than conventional plastics. LCA analysis demonstrates that these materials reduce carbon emissions and energy consumption. Despite challenges such as production costs and material durability, most consumers in Bandar Lampung prefer environmentally friendly packaging. This study provides insights into the potential implementation of biodegradable materials in Indonesia and their contribution to sustainable solutions in the packaging industry.

Abstract

This study analyzes the frequency and intensity levels of sound waves produced by musical instruments in the Bedana traditional dance of Lampung. An ethnoscience approach is employed, integrating cultural and scientific perspectives to examine sound phenomena in the local context. Data were gathered through sound frequency and intensity measurements using advanced audio analysis software, complemented by qualitative cultural observations. The results reveal distinct frequency variations among instruments, contributing to the dance’s harmonic expression. Notably, statistical tests indicate significance, reinforcing the hypothesis regarding the unique acoustic properties of each instrument. This research underscores the importance of ethnoscience in cultural conservation and traditional arts education, offering insights for future ethnomusicological studies and cultural preservation initiatives.

Abstract

The Socio-Scientific Issues (SSI) approach integrates social issues with scientific concepts to enhance the relevance of learning, including in the context of physics education. This study aims to systematically analyze the literature concerning the influence of the SSI approach on students’ learning outcomes in physics. The method employed is a Systematic Literature Review (SLR) guided by the PRISMA framework, which includes the stages of Identification, Screening, Eligibility, and Inclusion of articles published between 2020 and 2024 from the Google Scholar database. The data extracted from the selected articles were analyzed using a thematic analysis approach through manual coding, categorized into the domains of learning outcomes: cognitive, affective, and psychomotor. The analysis of 20 studies indicates that the implementation of SSI significantly improves students’ learning outcomes. Students exhibited deeper conceptual understanding, enhanced critical thinking skills, improved problem-solving abilities, increased scientific literacy, and more positive attitudes toward science. This study recommends the integration of the SSI approach into the physics curriculum to foster more contextualized and meaningful learning experiences.
