Abstract

This research study aimed to know the effectiveness of portfolio assessment in microbiology course on students’ self-regulated and learning outcome. This research was the experimental research of the pretes-posttest group design. The sample was 44 students of Nondik Biologi 2013. Self-regulated questionnaire and learning outcome test were used to measure self-regulated and learning outcome of students. Data were analyzed by using independent sample t-test with SPSS statistics 21 program. The results show that: (1) Students’ self regulated learning that assessed by portfolio bigger than assessed by paper test (tcount=3,105, p<0,05), the average score of students’ regulated learning on experimental class (score 81) > students on control class (score 76); (2) Students’ learning outcome that assessed by portfolio higher than assessed by paper test (tcount=2,861, p<0,05), the average score of students’ learning outcome on experimental class (score 86) > students on control class (score 80); (3) Effect size portofolio assessment application on students’ self regulated and learning outcome is  93% dan 81%, for each. This study conclude that portfolio assessment application effective on students’ self regulated and learning outcome in experimental microbiology, State University of Medan.

Abstract

The study aims to validate the textbook of Human Anatomy and Physiology. The validation conducted leads to the analysis of the textbook on scientific literacy, namely to determine the scope of scientific literacy in the textbook. This study is a descriptive study that aims to explain the validation results. This module was validated by three validators. There are four components that validated, namely content validity consisting of module components and the suitability of module content, construct validity, language validity, and suitability with learning that uses conceptual changes. The results of the validation of human anatomy and physiology materials for semester VI Biology students at Medan State University found that the standards for human anatomy and physiology teaching materials based on scientific literacy have met the Very Good category with a percentage score and an average number of feasibility: Content feasibility is 88.67, presentation feasibility 93%, feasibility of scientific literacy components 93%. The results of the study concluded three textbooks used in university emphasize more on the presentation of facts, concepts, principles, laws, theories and models and emphasize that students can remember information through questions.

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pendapatan kelompok budidaya ikan melalui penerapan inovasi pakan alami dan teknologi pemeliharaan modern. Permasalahan utama mitra adalah tingginya biaya pakan ikan yang mencapai 60–70% dari total biaya produksi, serta keterbatasan dalam penerapan teknologi tepat guna. Metode pelaksanaan meliputi sosialisasi, pelatihan pembuatan pakan alami berbasis maggot, desain dan fabrikasi mesin pencacah serta mesin pelet, serta pendampingan penggunaan teknologi pemeliharaan modern. Hasil kegiatan menunjukkan peningkatan pengetahuan dan keterampilan kelompok mitra dalam produksi pakan alami, peningkatan efisiensi biaya pakan, serta kemandirian dalam pemeliharaan ikan. Program ini memberikan dampak positif berupa penguatan kapasitas kelompok budidaya, peningkatan produktivitas, dan potensi peningkatan pendapatan. Keberhasilan kegiatan ini menunjukkan bahwa penerapan teknologi tepat guna dan inovasi pakan alami merupakan strategi efektif dalam pemberdayaan ekonomi masyarakat berbasis perikanan.

Abstract

The objectives of this study were to find out and knowing the effect of laboratory work on students’ learning activity and learning achievement on the topic of annelids and molluscs. This study was classified as quasi experimental with two group pretest – posttest design. This study was implemented at MAN 1 Medan grade X; samples of this study determined by cluster random sampling and obtained X-7 as experimental class and X-6 as control class. The study variable were consist of dependent variable, they are students’ learning activity and students’ achievement while the independent variable were using practicum method in experimental class and traditional method in control class. This study used test and non test instrument. Test instrument was cognitive test in form of multiple choice and essay whereas non test using observation sheet. The data analysis method was using t-test. The study result shows that involvement level of students’ learning activity on experimental class was higher than control class (62%> 45%). It means students’ learning activity in learning invertebrate subtopic that taught by practicum method more active than taught by traditional method. Average score of students’ achievements on experimental class was 83 (increase 34.17 point from pretest) and control class was 71.5 (increase 22.33 point from pretest). There was a significant difference between students’ achievement mean score on experimental class and control class then laboratory work have positive effect on students’ learning achievement in learning invertebrate subtopic at MAN 1 Medan.
