Abstract

This study aims to determine the effect of tomato paste on blood cholesterol in mice. It was an experimental study using a complete randomized study design consisting of four treatments P0, P1, P2, and P3 by giving tomato paste solution in a concentration of 0%, 20%, 40% and 80% and 6 replications. Data were analyzed using Anova one path and continued with BNT with a confidence level of 95%. The results showed that the tomato paste solution affected the blood cholesterol of mice due to Fhit (3.27)> F tab (3.10) and the treatment that gave the greatest effect was on giving the concentration of tomato paste solution by 80%.

Abstract

Learning media is one of the most important component in a learning process, both inside or outside a classroom. In order to provide proper learning for students based on the researcher’s prior research, at least, three different field tests are needed. This research is a quasi-experiment, which is provide result of the second field test of cellulose degrading bacteria from mangrove soil microbiology handout both in cognitive and psychomotor ability. The research aims are to describe effect of this microbiology handout on student’s cognitive achievement and gain data about inappropriate laboratory written instruction in this handout. Data gained by conducting learning activities using developed handout which were 2 times in class theory and three times of practical activity using instuctions written in the handout. In the end of class theory activity, students did a posttest to confirm their improvement of cognitive ability while their practical ability was observed using observation sheet along with their activities. Results showed that handout which being tested could improve student cognitive at average level (n gain 0,419). In contrast, several parts of laboratory written instruction need to be fixed to make better microbiology handout.

Abstract

Penyusunan instrumen penilaian dan pengembangan media pembelajaran IPA Berbasis Etno-STEM bagi guru sangat penting dilakukan. Oleh karena itu, dilakukan pengabdian masyarakat pada musyawarah guru mata pelajaran (MGMP) IPA Kabupaten karanganyar yang bertujuan untuk penyusunan Instrumen Penilaian dan Pengembangan Media Pembelajaran IPA Berbasis Etno-STEM bagi guru MGMP IPA. Kegiatan pengabdian kepada masyarakat ini dilaksanakan dalam beberapa tahapan, yaitu 1) Koordinasi dengan semua pihak terkait; 2) Focus group discussion pada beberapa masalah yang terjadi, solusi dan rencana tindak lanjutnya. Hasil  yang diperoleh  dari  pengolahan  data  keseluruhan  indikator  adalah  peserta  setuju bahwa  pelaksanaan pelatihan  telah  berjalan  dengan  baik,  dimana  sebagian besar peserta berpandangan bahwa pelaksanaan pelatihan telah memberikan manfaat  yang  mendalam dan sangat membantu dalam peningkatan kualitas diri peserta.

Abstract

This study aimed to see the effectiveness of the STEM-Guided Inquiry learning model based on local wisdom dawet ireng on the science literacy of 8th grade students on elemental, compound, and mixed materials. The type of research used is a quasi-experiment with a pretest-postest control group design. The population of this study was all VIII grade students of SMPN 35 Purworejo, Purworejo Regency in the 2023/2024 school year. The samples of this study were Class VIII C and Class VIII D obtained by cluster random sampling technique. Class VIII C (30 students) as a control class and Class VIII D (30 students) as an experimental class. Data collection was carried out using test techniques in the form of science literacy essay questions and non-tests in the form of science literacy questionnaires. Data validity is obtained from validity tests and reliability tests. Prerequisite data analysis applies the kolmogorow-smirnov normality test and levene homogeneity test. The research hypothesis used the right side hypothesis test (one-tailed) through the independent sample t-test and assisted by the SPSS 22 program. The results showed that the value of t-count > t-table, that is 15.613> 1.672 with a significant level of 5%, so H1 is accepted. The n-gain improvement test results also showed that n-gain score of the experimental class was 0.577 (medium category) and the control class -0.037 (low category). Based on the results of research and data analysis, it is concluded that the STEM-Guided Inquiry learning model based on local wisdom dawet ireng effectively improves the science literacy of 8th grade students in elemental, compound, and mixture materials.

Abstract

The low scientific literacy of students needs to be improved through the teaching materials used in learning. Teaching materials can be combined with various learning models including Ethno-STEM. The research aims to develop and test the feasibility of a module on vibrations and waves material in empowering science literacy ability of class VII students. The type of research carried out is development research using the 4D method including the define, design and develop stages. In this article, the research stage is written only up to the development stage. In the define stage, an analysis of gaps occurring in the field is carried out to define what is needed in the development process. In the design stage, the researcher prepares a product design according to the needs that have been summarized in the define stage. In the development stage, researchers began to develop modules according to needs and then carried out feasibility tests. Validation was carried out on aspects of material, media, language and learning. The overall module validation results obtained were 0.91 with valid criteria. Therefore, it can be concluded that the vibrations and waves module is effective to improve students' science literacy ability
