Abstract

Penelitian ini dilatar belakangi oleh rendahnya pemahaman siswa dalam proses pembelajaran yang berakibat pada hasil belajar siswa. Penelitian ini bertujuan untuk mengetahui pengaruh penerapan model Contextual Teaching and Learning (CTL) berbantuan media mind map digital terhadap hasil belajar IPA siswa SMPN 13 Samarinda. Penelitian ini merupakan penelitian kuantitatif dengan desain quasi eksperimen menggunakan non-equivalent control group design. Populasi penelitian berjumlah 270 siswa, dengan sampel kelas VII H sebagai kelas eksperimen dan VII G sebagai kelas kontrol, masing-masing berjumlah 30 siswa. Hasil penelitian menunjukkan bahwa data berdistribusi normal dan homogen. Uji Independent sample t Test menunjukkan nilai signifikansi (0,000 < 0,05), artinya terdapat pengaruh signifikan penerapan model Contextual Teaching and Learning (CTL) berbantuan media mind map digital terhadap hasil belajar siswa. Selain itu, penin gkatan hasil belajar pada kelas eksperimen berada pada kategori tinggi (rata-rata N-gain 0,77), sedangkan kelas kontrol berada pada kategori sedang (rata-rata N-gain 0,65). Model Contextual Teaching and Learning (CTL) berbantuan media mind maping digital efektif dalam meningkatkan hasil belajar IPA siswa SMPN 13 Samarinda.

Abstract

The inefficient implementation of learning approach and method can make student participant less active and leads to lack of critical thinking skills. This study aims to determine the effect of the deep learning approach using mnemonics on the critical thinking skills of seventh-grade students regarding the classification of living organisms at SMP Negeri 46 Samarinda. This study employed a quasi-experimental research design with a non-equivalent control group design. Sampling was conducted using purposive sampling, with a sample size of 25 students each for the experimental and control classes. The data analysis techniques used are N-Gain test and the Independent Sample T-Test. The results of the data analysis showed that the N-Gain score for critical thinking skills in the experimental class, with an average of 0.74, fell into the high category, while that of the control class, at 0.60, fell into the moderate category. The hypothesis results showed a significance value (2-tailed) of 0.000 for critical thinking skills, where this significance value (2-tailed) was < 0.05 so it can be concluded that there is an effect of the deep learning approach using mnemonics on the critical thinking skills of seventh-grade students regarding the classification of living organisms at SMP Negeri 46 Samarinda.

Abstract

The purpose of this research was to assess the impact of the STEAM-based PjBL model on the creativity of class X pupils at SMA Budi Luhur Samarinda in relation to ecology topics through outdoor activities. The methodology of this investigation was quasi-experimental and used a posttest-only control group approach. The study sample included 50 pupils, specifically class X-2, which used the STEAM-based PjBL approach through outdoor activities as the experimental class, and class X-1, which employed the PBL model as the control class. The sample was selected using a purposive sampling approach. A creativity observation rubric with markers for fluency, flexibility, originality elaboration, and individual contribution served as the research instrument. The SPSS version 25 was used to conduct data analysis, including hypothesis tests, normality tests, and homogeneity tests, utilizing independent sample t-tests. The study found that the average score for student creativity in the experimental group was 88.16, but the control group's score was 78.60. A hypothesis test yielded a significance value (Sig. 2-tailed) of 0.000 <0.05, leading to the rejection of H0 and the acceptance of Ha. Therefore, it may be deduced that the STEAM-based PjBL model has a considerable impact on the creativity of class X students at SMA Budi Luhur Samarinda when it comes to ecosystem content through outdoor activities.

Abstract

The armyworm is a major pest that can reduce crop yields. Control using chemical pesticides carries the risk of causing health problems, environmental pollution, and pest resistance. Therefore, safer and more environmentally friendly alternatives in the form of botanical pesticides are needed. This study aims to determine the effect of a combination of soursop leaf extract (Annona muricata L.) and PGPR (Plant Growth Promoting Rhizobacteria) from bamboo roots (Gigantochloa apus) on the mortality of armyworms (Spodoptera litura) on green mustard plants (Brassica juncea L). The experimental design used was a randomized block design (RBD), consisting of 8 treatments and 4 replicates, resulting in 32 experimental units. The results showed that soursop leaf extract and PGPR from bamboo apus roots, at an optimal concentration of 70%, significantly increased armyworm mortality to 85%.
