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.

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.
