Abstract

This research aims to analyze the correlation of 4C skill aspects based on students’ achievement in each aspect through GGE-JAS learning model. This research was conducted at SMA N 1 Tengaran, Semarang Regency with a quasi-experimental model and a non-equivalent group research design. The data collection method used was with test and non-test instruments. The results of this research in critical thinking skills in control class had an N-gain result of 0.36 in the low category and the experimental class was 0.53 in the medium category. This shows a striking difference before and after treatment in each class, so that the GGE-JAS model was effective. After the implementation of the GGE-JAS model in the experimental class, the achievement of critical thinking indicators was 73% in good category, collaboration skills was 83% in a very colaborative category, communication skills was 74.8% in a communicative category and creative thinking skills was 71.32% in creative category. The results of the correlation analysis stated that collaboration skills had a significant relationship with communication skills with t-value of 3.22 while creative thinking skills had a significant relationship with critical thinking skills with t-value of 2.04. The conclusion of this research is that GGE-JAS model is effective to improve students’ 4C skills in the mobility system material for class XI MIPA SMA N 1 Tengaran, Semarang Regency and students’ collaboration skills are significantly positive related to students’ communication skills, while students’ creative thinking skills have a significant positive relation with students’ critical thinking skills.

Abstract

Background: The purpose of bioremediation is to remove or reduce dangerous compounds to improve environmental quality, one of which is heavy metals. Metal-binding proteins can minimize the impact of heavy metal pollution from the environment. This metal binding protein can accumulate metals by microorganisms. One of the known metal-binding proteins is metallothioneins (MTs). This protein can minimize the effects of heavy metals in the environment by creating protein-metal ion complex bonds. This review article provides a comprehensive insight into the role of metallothionein as a metal-binding protein for heavy metal accumulation, and the mechanisms involved in heavy metal bioremediation Methods: The method used is a literature review using reputable national and international journals. Results: Based on the results of a literature review, metallothionein can be found in many organisms such as bacteria, humans, plants, invertebrates, and mammals. Metallothionein can accumulate heavy metals that contain highly conserved cysteine residues. These residues allow MTs to bind, transport, and store various essential (Zn and Cu) and non-essential (Cd and Hg) heavy metals via thiolate bonding. Conclusion: Heavy metals are dangerous for the survival of living things and can cause damage to vital functions. One of the metal-binding proteins is metallothionein, which is involved in the organism's tolerance to heavy metal content and can accumulate it, so that the effects of heavy metals can be minimized.
