Abstract

Perubahan paradigma pembelajaran mengarah ke student centered dan peserta didik perlu dibekali keterampilan berpikir kritis. Hasil observasi peneliti yang dilakukan saat kegiatan magang 2 pada bulan September sampai bulan November tahun 2019, menunjukkan bahwa kegiatan pembelajaran yang mengarah pada pengembangan keterampilan berpikir kritis kurang diterapkan dalam proses pembelajaran. Hal ini terlihat dari perangkat pembelajaran yang masih banyak bersumber dari buku pelajaran dan internet yang belum relevan dengan lingkungan kehidupan sehari-hari peserta didik. Demikian juga dengan komponen-komponen perangkat pembelajaran berupa silabus, Rencana Pelaksanaan Pembelajaran (RPP), Lembar Diskusi Peserta Didik (LDPD), dan soal evaluasi. Penelitian ini bertujuan untuk mendeskripsikan rancangan perangkat pembelajaran yang dapat digunakan untuk mengembangkan keterampilan berpikir kritis siswa. Jenis penelitian ini termasuk ke dalam penelitian deskriptif kualitatif. Penelitian ini akan menganalisis rancangan RPP meliputi telaah kompetensi dasar, telaah materi pembelajaran, telaah indikator, tujuan pembelajaran, telaah model pembelajaran, metode pembelajaran, dan telaah media pembelajaran menggunakan model kooperatif tipe Think, Talk, Write (TTW) metode gallery walk pada materi pencemaran lingkungan kelas X.

Abstract

Organic wastes of tilapia offal, coconut pulp, and plantain are rarely optimally utilized, but they can be degraded by BSF larvae into nutritious biomass. This study aims to analyze the combination of organic waste macronutrient feed on bioconversion, survival, growth (weight, length, and thickness), and nutritional value (protein, fat, and carbohydrates) of BSF prepupae, using the Completely Randomized Design (CRD) method, 4 treatments P1 (50% tilapia offal: 25% plantain: 25% coconut pulp), P2 (25% tilapia offal: 50% plantain: 25% coconut pulp), P3 (25% tilapia offal: 25% plantain: 50% coconut pulp), P4 (33.3% tilapia offal: 33.3% plantain: 33.3% coconut pulp) and 3 repetitions. All treatments resulted in optimal survival (100%, survival). P4 produced an ECD value of 0.034% and WRI of 0.032% indicating the best efficiency and waste reduction. P1 was the best variation for weight at 5.69 g, length 19.7 mm, and thickness 5.8 mm. The Post Hoc Tuckey test showed no significant difference between treatments in weight and thickness parameters, but not in length parameters (<0.05). The protein content of P1 43.75%, fat P2 29.764%, and carbohydrate P2 1.374% were close to SNI 7994:2014 (meat bone meal, quality II). It was concluded that macronutrient feed waste affects bioconversion, survival, growth and nutritional value of BSF.

Abstract

This study aimed to determine the effect of salung (Psychotria viridiflora) leaf extract on blood glucose levels in hyperglycemic mice (Mus musculus). A total of 25 mice weighing 20–40 grams were divided into five treatment groups: P1 (negative control: feed and distilled water), P2 (alloxan 10 mg/kg BW + glibenclamide 0.1 mg/kg BW), P3 (alloxan 10 mg/kg BW + P. viridiflora leaf extract 0.0112 g/kg BW), P4 (alloxan 10 mg/kg BW + P. viridiflora leaf extract 0.0225 g/kg BW), and P5 (alloxan 10 mg/kg BW + P. viridiflora leaf extract 0.0337 g/kg BW). Blood glucose levels were measured four times—on days 0, 6, 12, and 18—covering baseline measurement, post-alloxan induction, and after treatment administration. The results showed that the highest dose (0.0337 g/kg BW) was the most effective in reducing blood glucose levels in alloxan-induced mice, with an effect comparable to the standard drug glibenclamide. In conclusion, P. viridiflora leaf extract has potential as an alternative herbal antidiabetic therapy in M. musculus.  Keywords: Antidiabetic, Blood Glucose, Extract Leaf, Hyperglycemia, Mus musculus, Psychotria viridiflora

Abstract

Low levels of disaster literacy and critical thinking among students highlight the need for innovative and contextualized learning media in science education. This research develops and evaluates the effectiveness of a flood disaster mitigation science E-comic to enhance students’ critical thinking and disaster preparedness. The study employed a Research and Development (R&D) approach using the 4D model (Define, Design, Develop, and Disseminate). Validation results indicated that the E-comic is feasible as a learning medium, with CVI values of 0.89 (media) and 1.00 (content). The use of the E-comic effectively improved students’ critical thinking skills and disaster preparedness, as evidenced by high N-Gain scores and significant statistical results. The improvement was consistently observed across all disaster preparedness indicators, including knowledge, attitudes, and response planning. The study concludes that the flood disaster mitigation E-comic is both effective and feasible as a contextual science learning medium. The integration of flood-related physical science concepts demonstrates how contextualized media can strengthen scientific literacy in disaster education.

Abstract

Waste from male banana peels (Musa paradisiaca Var. Paradisiaca), Ambon banana peels (Musa paradisiaca Var. Sapientum), and kepok banana peels (Musa acuminate L.) can be used as natural water filtration. The content of pectin, galacturonic acid and cellulose in banana peels can absorb heavy metals in water. This research aims to determine the filtration ability of natural waste materials such as kepok banana peels, Ambon banana peels and male banana peels which are most effectively used as water filtration media. This research consists of the sample preparation stage, carbonization stage, activation stage, and trial stage. The method used is an experimental method on a laboratory scale to measure Potential Hydrogen (pH), Total Dissolve Solid (TDS), and the level of clarity in water. The data obtained was tested using the Anova test with a significance level of 5% and the BNT test. Based on the BNT test which shows that male banana peels are not significantly proportional to the TDS of well water. Meanwhile, Ambon banana peel and Kepok banana peel are significantly proportional to TDS, and for Kepok banana peel, Ambon banana peel and male banana peel, it is significantly proportional to the pH of well water, because the significance results are less than 0.05%. From these findings it can be concluded that Kepok banana peels and Ambon banana peels are the most effective water filtration media to use.

Abstract

Earthworms (Lumbricus rubellus) are beneficial invertebrates that reduce waste, animal feed, and cosmetic raw material. The research was conducted at Ruyani Life Sciences Learning Resources (SBIH), Bengkulu (Ruyani et al., 2018), from September to November 2023. The design of this study adopted a Complete Randomized Design (RAL) consisting of five experimental groups with different feed comparisons (in %).Earthworm growth and development are optimized in their natural habitat, which includes temperatures ranging from 15℃ to 25℃, soil moisture and air availability between 15% and 30%, soil pH levels between 6.0 and 7.2, and the presence of organic matter for food. The study fed earthworms a diet consisting of tofu residues and cow dung in different proportions: (a) 100% tofu residues and 0% cow dung; (b) 75% tofu residues and 25% cow dung; (c) 50% tofu residues and 50% cow dung; and (d) 25% tofu residues and 75% cow dung. The research findings indicated that the ideal feed composition for maximizing earthworm biomass production is 25% tofu residues and 75% cow dung. Additionally, the most effective ratio of individual earthworms throughout a four-week maintenance period is 75% tofu residues and 25% cow dung.

Abstract

This study aims to enhance cognitive and psychomotor abilities through outdoor learning, designed and evaluated collaboratively by the learning community within the framework of the Lesson study. The study was conducted on grade X students of MAN Insan Cendekia Bengkulu Tengah. Lesson study was carried out in two cycles, each consisting of the plan, do, and see stages. The "plan" stage is the planning stage to prepare the learning tools and strategies that will be carried out. The "do" stage is the implementation of the learning that has been designed. The "see" stage is a reflection of the learning activities that have been carried out. The instruments used consist of observation sheets and test paper. Data is analyzed by calculating the average percentage of each observation indicator, while cognitive and psychomotor learning outcomes are analyzed by calculating the average value obtained. Implementation of the lesson study achieved a percentage score of 100%. Cognitive learning outcomes from cycle I to cycle II increased by 20.43%. Meanwhile, psychomotor learning outcomes increased by 26.79%. The ecosystem acts as a direct learning context that does not only present objects of study to be studied but can also facilitate students to develop conceptual understanding and scientific skills simultaneously. Thus, the reflection carried out will encourage teachers to make continuous improvements. The conclusion of this study is that lesson study activities involving the role of the learning community can improve the planning, implementation, and reflection of biology learning outside the classroom, thus having a significant impact on improving students' cognitive and psychomotor learning outcomes.
