Abstract

Project Based Learning (PjBL) is a learning model that emphasizes active student involvement in the learning process through contextual and meaningful project activities. This study aims to analyze the application of the Project Based Learning (PjBL) model to the concept of global warming and its impact on the knowledge of tenth-grade students. This study used a quantitative approach with a quasi-experimental method and a pretest–posttest control group design. The research sample consisted of two classes: class IA X-1 with 22 students as the experimental class and class IA X-2 with 21 students as the control class, resulting in a total sample of 43 students. The experimental class was given treatment in the form of learning using the PjBL model, while the control class used conventional learning. The research instrument was a knowledge test administered before and after the treatment. Data were analyzed using descriptive statistics and N-Gain calculations. The results showed that there was a difference in knowledge gain between the experimental and control classes. The increase in student knowledge in the experimental class was higher than in the control class, with the N-Gain results being in the moderate to high category. Based on these results, it can be concluded that the implementation of the Project Based Learning (PjBL) model is effective in increasing student knowledge on the concept of global warming.

Abstract

Science learning in elementary schools is often dominated by conventional methods, resulting in low science literacy and limited student participation. This study aims to examine the effectiveness of practicum-based Project Based Learning in improving science literacy and student participation. A quantitative approach with a one-group pretest–posttest design was employed involving 34 fifth-grade students. Data were collected through science literacy tests and observation sheets of student participation. The results showed a significant improvement in students’ science literacy, with the average score increasing from 68.41 to 86.76 and an N-Gain score of 0.58, categorized as moderate. In addition, student participation improved as reflected in increased engagement during discussions, experiments, and project activities. These findings indicate that practicum-based Project Based Learning provides meaningful learning experiences and effectively enhances both science literacy and student participation.

Abstract

This research aims to analyze the local wisdom of the community in rice field conservation and identify customary sanctions for violations that occur. The research uses a qualitative approach with data collection techniques in the form of observation and interviews. The research subjects consisted of the imeum mukim, keujreun blang, and the community of Ateuk Mon Panah Village, Simpang Tiga District, Aceh Besar Regency, with a total of 30 respondents. The results of the study show that local wisdom in the form of meugoe (rice fields) customs, especially related to the order of going down to the rice fields, has been inherited from generation to generation and is still maintained to this day. In addition, there are customary sanctions imposed for violations, such as water theft, in the form of sanctions in the form of the obligation to make talam cakes up to 1000 pieces or the slaughter of goats, depending on the level of violation. Local wisdom in the practice of meugoe has been proven to be in line with the principles of rice field and environmental conservation. Therefore, the preservation of these traditional values is important to support environmental sustainability and can be used as a source of learning for the community and the world of education.

Abstract

This study aims to analyze the effectiveness of the implementation of the Project-Based Learning (PjBL) model based on local potential on biotechnology material in improving students' critical thinking skills and scientific attitudes. The study used a quantitative approach with a one-group pretest-posttest design for 35 students. The instruments were a critical thinking test and a scientific attitude observation sheet that had been declared valid and reliable (Cronbach's Alpha = 0.789). The results showed a significant increase in critical thinking skills, with an average pretest score of 17.63 increasing to 37.71 in the posttest, and an N-Gain value of 0.897 (high category). The increase occurred in all indicators, with the highest value in the indicator providing simple explanations (0.9226) and the lowest in the indicator organizing strategies and tactics (0.8723), but all in the high category. Students' scientific attitudes also increased, indicated by an average pretest score of 17.49 to 29.51 in the posttest, with an N-Gain value of 0.808 (high category). The highest improvement was found in the critical thinking indicator (0.93), while the lowest was in the collaboration indicator (0.63). Thus, the local potential-based PjBL model effectively improves students' critical thinking skills and scientific attitudes through contextual and project-based learning.

Abstract

This study aims to develop an outdoor laboratory-based Discovery Learning model on the characteristics of living things to improve scientific literacy and science process skills of students at MTsN 3 Banda Aceh. The method used is development research with the 4D model (Define, Design, Develop, Disseminate). Product validation was carried out by material experts and learning experts, while practicality was measured through teacher and student responses, and effectiveness was measured by N-gain and paired sample t-test. The validation results of material experts reached 85.27% and 85%, learning experts 84% and 86% (valid category). Teacher responses were 86.25% and student responses 86.62% (strong category). The N-gain value was 0.73 (high criteria) with a T-test significance value of 0.000 <0.05. It was concluded that the outdoor laboratory-based Discovery Learning model is valid, practical, and very effective in improving students' scientific literacy and science process skills.

Abstract

Daun Kersen (Muntigia calabura L.) adalah salah satu herbal yang yang secara tradisional digunakan untuk menurunkan kadar gula darah pada pasien diabetes melitus. Tujuan penelitian ini untuk mengetahui apakah terdapat pengaruh uji ekstrak etanol daun kersen terhadap histologi hepar tikus putih (Rattus norvegicus) yang diinduksi streptozocin (STZ) Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian naratif, serta eksperimen menggunakan metode Rancangan Acak Lengkap (RAL). Penelitian ini menggunakan 5 kelompok percobaan dengan tiga kali pengulangan. Penelitian ini dilakukan pada tanggal 08 Mei sampai 22 Mei 2023. Objek dalam penelitian ini ialah 30 ekor tikus putih (yang telah diinduksi STZ sehingga menyebabkan diabetes mellitus. Analisis data dilakukan dengan pengamatan gambar melalui histopatologi hepar tikus. Hasil penelitian diperoleh bahwa pada larutan aquades (K1) terlihat gambaran normal sel hepatosit berderet secara radier pada lobulus hepar. Pada K2 (diinduksi STZ 30 mg/kilo Gram BB), sel hepatosit mengalami bengkak keruh dan nekrosis menggunakan inti piknotik, pada K3 (diinduksi STZ 30 mg/kg BB dan + obat metformin), terlihat sedikit sel yang mengalami degenerasi perlemakan dengan terbentuknya vakuolisasi lemak pada sitoplasma sel, di K4 (diinduksi STZ 30 mg/kg BB dan ekstrak daun kersen 10%), menunjukkan sel mengalami degenerasi, adanya interim, pada K5 (diinduksi streptozocin 30 mg/kgBB serta diberikan ekstrak etanol daun kersen 15%), sel hati berbentuk normal, dimana sel hepatosit berderet secara radier dalam lobulus hati. Dengan demikian ekstrak etanol daun kersen berdosis 15%, efektif dalam memperbaiki kerusakan sel di pada tubuh dampak asal zat tosik STZ sehingga dapat menurunkan kadar glukosa darah didalam tubuh.
