ABSTRACT   Based on the results of observations at SLB Negeri 5 Bengkulu City, teachers need innovative science teaching materials that can support the needs of mentally retarded students in learning, one of which is in the form of teaching materials in the form of illustrated electronic handouts. This study aims to produce electronic handouts with the theme of animal diversity based on KOKO (Contextual and cooperative) for mentally retarded students by looking at the feasibility of the product and the teacher's response. This research is a developmental research with a 4-D model. consists of 4 stages, starting from definition, design, development, and deployment. However, this research is limited to the develop stage only. The types of data obtained are qualitative and quantitative. The results showed that the material aspect was declared very feasible with a percentage of 93%, the language aspect was obtained with a percentage of 94% with a very feasible category and the media aspect was obtained with a percentage of 95% with a very feasible category. So that the electronic handout developed is very feasible to continue at the field test stage. The results of the analysis of content validation used the Aiken V formula. The content validity value for the material aspect was 0.91 with high validity criteria, the content validity value for the language aspect was 0.92 with high validity criteria. The content validity value for the media aspect is 0.93 with high validity criteria. The average content validity value for the total validation results is 0.94 with high validity criteria. Based on the results of the teacher's response questionnaire to the electronic handout with the theme of animal diversity based on the KOKO (Contextual and Cooperative) animal breeding sub-theme at SLB Negeri 5 Bengkulu City, the results of 93% of the teacher's response were stated to be very good.  Keywords: Mentally Retarded, Electronic Handout, KOKO.

Abstract

The purpose of this study was to determine the diversity of gastropods on Cukuh Raya Beach, Kaur Regency and to produce a valid classification booklet of living things. Based on the results of sampling at Cukuh Raya Beach, 12 species of gastropods were obtained, namely: M. annulus, T. chrysostomus, T. canaliculatus, R. aspera, N. canrena, C. femorale, V. musica, N. undata, T. radiatus G., R. nilotica, O. sayana R., and O. polpasta D. The research and development design used, namely (R&D) is based on the 4-D model starting from defining (Define), designing (Design), developing (Develop), and disseminating (Disseminate), but only carried out up to the development stage. The booklet developed was made with an attractive cover and Open Sans font that is in accordance with EYD. The booklet contains a front cover, foreword, table of contents, learning objectives, indicators of learning objective achievement, summary of materials, gastropod diversity, evaluation questions, and bibliography. The average results by expert (lecturer) and practitioner (teacher) validation obtained a percentage of the booklet content aspect of 90%, language aspect of 93.8%, and graphic/design aspect of 88.6% with an average of 90.8% in the category of "very feasible". Thus, it can be concluded that the developed product is very feasible to be tested in the learning process.

Abstract

The purpose of this study was to enhance critical thinking skills through the implementation of coastal culture-based differentiated science learning. The research was conducted from August to November 2024 using a quasi-experimental nonequivalent control group design at SMP Negeri 2 Bengkulu, Indonesia. The sample consisted of three eighth-grade classes: experimental group 1 (8A), experimental group 2 (8B), and the control group (8C), selected through purposive sampling. Students’ critical thinking skills were assessed using a validated and reliable test instrument (r = .89). Data were analyzed with one-way ANOVA, which revealed significant differences among groups (p < .001). The average N-gain score of critical thinking skills in experimental group 1 (.40, medium category) was higher than that of experimental group 2 (.20, low category) and the control group (.009, low category). Based on the hypothesis testing, it can be concluded that coastal culture-based differentiated science learning has a significant effect on students’ critical thinking skills (p < .001). These findings confirm that culturally contextualized differentiated learning significantly enhances critical thinking. Theoretically, this model contributes to science pedagogy by integrating cultural relevance to support effective, innovative instruction

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
