Abstract

Critical thinking is an ability that must be possessed by students because critical thinking is a basic skill needed in 21st century learning. In natural sciences, the problems that are often raised are environmental problems which are related to living things. By raising general problems that occur in the environment and living things, this can be used as an aspect of discussion in biology learning, such as in heredity material which studies how the inheritance of traits is passed down from parents to offspring and evidence of inheritance, as well as studying the determinants of genetic disorders. in living things. Students' critical thinking ability is assessed based on indicators of critical thinking skills consisting of interpretation, analysis, inference, evaluation, explanation, and self-regulation.The purpose of this study is to analyze the critical thinking skill of 9th grade junior high school students at SMPN 5 Kudus in solving problems question related to heredity based on measurement that is described from indicators of critical thinking ability. Of the 26 students, the average percentage of critical thinking skills in students from the six critical thinking indicators is 81% and belongs to the high category, because of the teacher's role in directing students to be able to improve their critical thinking skills and the characteristics of critical thinking skills that each student has.

Abstract

Jahe merupakan tanaman herbal dengan peminat yang tersebar di seluruh dunia. Menurut data yang disebutkan oleh Food and Agriculture Organization di tahun 2019, produksi jahe di Indonesia sebanyak 174 ribu ton dan Indonesia menempati urutan keenam sebagai negara dengan hasil produksi jahe terbesar di Asia. Tingginya minat masyarakat terhadap jahe mengakibatkan melonjaknya produksi jahe sehingga muncul permasalahan baru salah satunya kerusakan pada rimpang jahe. Sehingga alternatif pengendalian dengan fungisida alami diperlukan. Buah pinang memiliki kandungan senyawa bioaktif seperti saponin, flavonoid, tannin, phenol, steroid, alkaloid yang dapat berperan sebagai anti-kapang. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan ekstrak buah pinang muda terhadap  pertumbuhan kapang pada rimpang jahe segar dan simplisia kering rimpang jahe. Hasil yang diperoleh pada penelitian ini adalah adanya penghambatan pertumbuhan kapang dari penambahan ekstrak dengan pengenceran. Sedangkan perlakuan ekstrak tanpa pengenceran kurang memberikan pengaruh dalam penghambatan pertumbuhan kapang.

Abstract

This study aims to determine the impact of utilization Computer Assisted Instruction (CAI) based learning media in improving digital literacy skills and student learning outcomes. In this study, data collection used observation sheets to improve students' digital literacy skills through observations of experimental and control groupes. It is known that the score of students' digital literacy skills is 81% in the experimental group, while the control group is 67%, meaning that the criteria for students' digital literacy skills in the experimental group are classified as better.  In collecting data to determine the effect of media on student learning outcomes, the Pretest Posttest control group design method is used with a pretest, treatment, and posttest pattern. In practice, 2 groupes are needed as experimental groupes with treatment and control groupes without treatment, and observations are made of students' digital literacy skills during learning activities. From the results of the analysis of student pretests and posttests, it is known that there is an increase in scores in the experimental group as indicated by the average N-Gain value of 57.54%, thus the use of CAI-based learning media is interpreted in the category quite effective in improving student learning outcomes. Then based on the results of the one-way anova analysis for the relationship between the improvement of learning outcomes with digital literacy skills in experimental and control groupes, it is known that the significance value is 0.00 <0.05, as well as the results of the post-hoc test with the Turkey method which shows the significance value between digital literacy and learning outcomes is less than 0.05, which means that the use of CAI-based learning media has an influence on digital literacy as well as student learning outcomes. So it can be concluded that the use of CAI-based media has an impact in improving digital literacy skills and student learning outcomes.
