Abstract

Penelitian ini bertujuan untuk mengukur peningkatan keterampilan pemecahan masalah siswa melalui penerapan model pembelajaran Problem Based Learning (PBL). Subjek penelitian adalah siswa kelas VIII-A UPT SMP Negeri 10 Gresik, dengan metode kuantitatif design menggunakan rancangan one group pretest-posttest. Keterampilan pemecahan masalah siswa diukur dengan instrumen pretest dan posttest yang berisi 12 soal pilhan ganda berdasarkan indikator PISA. Hasil analisis data menggunakan uji N-Gain menunjukkan 57% siswa berada dalam kategori tinggi, 33% dalam kategori sedang, dan 3% siswa mendapatkan kategori rendah. Indikator tertinggi adalah Planning and Executing (PE) dengan N-gain sebesar 0,86, sementara indikator terendah adalah Exploring and Understanding (EU) dengan N-gain sebesar 0,60. Kesimpulannya, penerapan model PBL terbukti efektif dalam meningkatkan keterampilan pemecahan masalah siswa.

Abstract

Virgin Coconut Oil (VCO) merupakan minyak nabati yang diekstrak dari endosperma kelapa segar dan matang tanpa penyulingan kimia atau panas tinggi. VCO dapat diproduksi dengan beberapa metode, salah satunya adalah metode enzimatik nanas. Hasil produksi VCO enzimatik nanas memiliki keunggulan dibandingkan metode lainnya. Nanas merupakan tanaman yang relatif mudah dibudidayakan di Indonesia, namun pemanfaatan nanas masih belum maksimal, biasanya hanya sebagai olahan makanan atau minuman yang dapat dikonsumsi langsung. Penelitian ini bertujuan untuk mengetahui cara produksi VCO menggunakan metode enzimatik dari buah nanas dan parameter fisik VCO yang dihasilkan. Metode yang digunakan dalam penelitian ini adalah metode campuran. Hasil penelitian ini menghasilkan minyak sebanyak 40 ml dengan kejernihan bening, aroma sedikit menyengat khas kelapa, dan memiliki rasa khas minyak kelapa.

Abstract

Pedagogical competence is very necessary to improve the learning process. Pedagogical competency is a competency that prospective science teachers must have. This relates to the duties of teachers who are not only teachers, but also as educators and mentors of students. Prospective teachers need to have both academic and non-academic competencies. This research aims to analyze the pedagogical competence of prospective teachers in terms of their ability to prepare learning plans. The method used by researchers in this research is a project with a quantitative approach. The research results show that prospective science teacher students are able to design learning by implementing innovative learning models, utilizing relevant technology, with the hope of making it easier for students to understand the learning material

Abstract

Motivation and learning outcomes are two interrelated aspects. A high level of learning motivation will result in commitment and resilience in learning, thereby leading students to improve their learning outcomes. This research aimed to describe the improvement of learning outcomes and student motivation after application experimental methods in science learning on the topic of dynamic electricity. This research is a type of Classroom Action Research design consisting of two cycles with instruments in the form of formative test sheets and questionnaires where there are 30 students as research subjects. Based on the results of the formative test in cycle I, an average score of 85.4 was obtained and increased to 88.7 in cycle II. The classical learning completion in cycle I was 53.3% and increased to 86.7% in cycle II. According to the questionnaire’s results, it is known that 100% of respondents thought that using experimental methods to teach science was very interesting and enjoyable. In addition, 83.3% of respondents stated that experimental methods can increase their motivation to learn on dynamic electrical materials. Consequently, it might be concluded that the application of experimental methods is significantly able to improve student learning outcomes and motivation.

Abstract

Caisim (Brassica juncea L.) is a widely consumed leafy vegetable that requires adequate nutrients for optimal growth. This study aimed to investigate the effect of rabbit manure on the growth of caisim plants, specifically focusing on fresh weight, dry weight, and root length. The experiment was conducted using a Completely Randomized Design (CRD) with five treatments and five replications. Treatments consisted of different soil-to-rabbit manure ratios: P0 (control, no manure), P1 (1:1), P2 (2:1), P3 (3:1), and P4 (4:1). The results showed that the application of rabbit manure significantly affected all three observed growth parameters. The best results were obtained in the P2 treatment (2:1 ratio), which yielded an average fresh weight of 21.902 g, a dry weight of 1.17 g, and a root length of 5.58 cm. These findings suggest that rabbit manure supplies essential nutrients, including nitrogen, phosphorus, and potassium, which contribute to enhanced root development and overall plant growth. The 2:1 ratio was found to offer the most effective nutrient balance for caisim cultivation. The implication of this study is that rabbit manure can serve as an environmentally friendly and effective organic fertilizer alternative to chemical fertilizers, supporting sustainable agricultural practices and offering a practical solution for enhancing the productivity of horticultural crops.
