Abstract

This study aims to determine the effect of the STEM-based project-based learning (PjBL) model on students' creative thinking skills and learning motivation in biology at SMA Negeri 4 Palu. The study used a quantitative approach with a quasi-experimental design, the population in this study were all grade X students of SMA Negeri 4 Palu in the 2024/2025 academic year consisting of 12 study groups with a total of 400 students. The sample was determined through purposive sampling, consisting of an experimental class (n=33) receiving PjBL-STEM learning and a control class (n=33) with conventional learning. Data were collected through creative thinking skills tests and learning motivation observation sheets, then analyzed using normality tests, homogeneity tests, and independent samples t-tests. The results showed that the PjBL-STEM model had a significant effect on improving creative thinking skills (Sig. = 0.023 <0.05) and learning motivation (Sig. = 0.000 <0.05). This finding confirms that the integration of the STEM approach in PjBL not only strengthens the cognitive but also the affective aspects, so that it can be used as a strategic alternative in developing a biology curriculum to foster 21st-century competencies.

Abstract

Tujuan peneltian ini adalah untuk mengkaji bagaimana pola makan dan prestasi belajar siswa, selain itu untuk menentukan seberapa besar hubungan pola makan terhadap prestasi belajar anak Sekolah Dasar Inpres LIK Layana Indah di Kota Palu. Adapun jenis penelitian yang digunakan adalah deskriptif kuantitatif. Populasi dalam penelitian ini berjumlah 198 siswa, dan sampel yang diambil berdasarkan teknik purposive sampling sebanyak 60 siswa. Teknik analisis data menggunakan analisis univariat dan bivariat menggunakan perangkat lunak SPSS 23. Hasil penelitian menunjukkan bahwa mayoritas siswa memiliki pola makan paling banyak berada pada kategori baik berjumlah 30 siswa (50,0%) dan prestasi belajar paling banyak berada pada kategori baik dengan jumlah 36 siswa (60,0%). Selain itu, hasil uji statistic person product moment didapatkan nilai p (0.003 < 0.05) menunjukan terdapat hubungan yang signifikan antara pola makan dengan prestasi belajar siswa. Sehingga dapat disimpulkan bahwa semakin baik pola makan siswa, semakin baik pula prestasi belajar siswa SDN Inpres LIK Layana Indah di Kota Palu.

Abstract

This study aims to determine the effect of Problem Based Learning (PBL) learning model on students' biology problem solving skills in class VIII SMP Negeri 19 Palu. The method used was a quasi-experiment with Non equivalent (Pretest and Posttest) Control Group Design. The research sample amounted to 46 students, consisting of 23 experimental class students who used the PBL model and 23 control class students who used the conventional learning model. Data were collected through observation, teacher and student activity assessment sheets, and tests in the form of valid and reliable description questions. Data analysis was carried out with prerequisite tests, namely normality test and homogeneity test, as well as hypothesis testing using Independent Sample t-test. The results showed that there was a significant effect of PBL model on students' biological problem solving ability. The average posttest score of the experimental class reached 91.73, while the control class was only 75.21. The t-test shows a p value <0.05, which means that the alternative hypothesis is accepted, indicating that the application of the PBL model has a positive effect. Thus, it can be concluded that the PBL model is effective and influential on students' biology problem solving skills in science subjects of class VIII-D SMP Negeri 19 Palu.

Abstract

This study aims to determine the amount of macronutrient content contained in Moringa leaf crackers (Moringa oleifera). This study used a Complete Random Design (RAL) and was an experimental study using moringa leaf flour formulations, namely F0 (0%), F1 (10%), F2 (15%), and F (20%) each treatment was repeated 3 times. The analysis data with the Analysis Of Variance (ANOVA) statistical test showed the real difference between treatments. Determination of protein content using the Anthrone method, protein content using the Biuret method, and determination of fat content using Soxhlet. The results showed that the carbohydrate content in the formula of 10% moringa leaf flour was 0.47%, the formula of 15% moringa leaf flour was 0.41%, the formula of 20% moringa leaf flour was 0.34%, the protein content in the formula of 10% moringa leaf flour was 0.262%, the formula of 15% moringa leaf flour was 0.313%, and the formula of 20% moringa leaf flour was 0.322%. The fat content in the 10% moringa leaf flour formula is 10.28%, the 15% moringa leaf flour formula is 13.76% and the 20% moringa leaf flour formula is 28.26%.

Abstract

This study aims to describe the effectiveness of the use of biology laboratories on student learning outcomes at SMA Negeri 1 Tikke Raya. This type of research uses a quantitative quasi-experimental design using a pretest and posttest control group design. Quantitative data are in the form of measurement results of student learning outcomes. The population in this study were all 145 students of class X of SMA Negeri 1 Tikke Raya. Sampling used a purposive sampling technique, and the sample in this study was 2 classes consisting of class X1 as the Experimental Class and X2 as the control class. Data collection techniques used observation and tests. The results showed that the use of biology laboratories proved to be more effective in improving the learning outcomes of class X students of SMA Negeri 1 Tikke Raya compared to conventional methods. The results of the analysis showed an increase in both groups, but the experimental group obtained significantly higher post-test scores, indicating that the use of laboratories had a positive effect on biology learning outcomes.
