Abstract

Poverty is a condition that results in an inability to meet basic needs such as housing, food, education, and health. Based on data from the Central Statistics Agency (BPS), the number of poor people in Indonesia in September 2019 was 24.79 million. To minimize social welfare problems, especially the problem of increasing poverty, the Government of Indonesia issued policies related to empowering poor families. The government policy is the Family Hope Program (PKH), but the Implementation of the Family Hope Program (PKH) has not been implemented on target. This has resulted in social jealousy between residents in the community [1], one of the villages where PKH assistance distribution is still not on target is Gilih Suka Negeri Village. Gilih Suka Negeri Village is one of the areas in Lampung Province, North Lampung Regency, South Abung District, which has a total of 7 RTs (RTs) with a population of approximately 1,776 people. The author chose algorithm method C4.5 (Decision Tree) because it can be used as a solution to determine the classification of beneficiaries. Algorithm C4.5 (Decision Tree) will classify beneficiaries of the Family Hope Program (PKH) based on how much they earn, where they live, and how many people they have in their household

Abstract

Environmental issues caused by plastic waste have become both an ecological and humanitarian crisis. In response to this reality, this study aimed to explore how the song Plastic Tree by Endah N Rhesa serves as an agent of ecological critique through poetic symbolism. Using Ferdinand de Saussure’s semiotic approach, the song lyrics were analysed as signs conveying hidden environmental meanings. Symbols such as “plastic tree,” “rubber bee,” and “paper bird” reflect the loss of natural ecosystems replaced by lifeless artificial objects. The analysis revealed that the song successfully builds ecological awareness and rejects superficial solutions, thereby encouraging listeners to become more reflective and concerned about their surrounding environment.

Abstract

This study aims to examine the effectiveness of the Project-Based Learning model with an Ethno-STEM approach in enhancing students’ critical thinking skills. This research employed a quantitative method using a quasi-experimental nonequivalent control group design, with sample selection conducted through purposive sampling. The sample was selected using purposive sampling. The research subjects were eighth-grade students, assigned to an experimental class and a control class. Data were collected through critical thinking skill tests in the form of essay questions administered before and after the treatment. The results of the independent sample t-test (0.001 < 0.05) indicate a significant difference in students’ critical thinking skills between the experimental and control groups. The N-Gain analysis shows that the increase in critical thinking skills in the experimental class (0.50) was higher than in the control class (0.34). Based on these findings, it can be concluded that the Project-Based Learning model with an Ethno-STEM approach is effective in improving students' critical thinking skills.
