Abstract

Structure adaptation is caused by the interaction of plants with the environment, so it requires system thinking in understanding it. This study was conducted to examine the instructional impact of the Multiple Representations Supported Argumentation (MRSA) learning model which involves students doing reasoning using multi representations to facilitate complex system modeling skills. The study was conducted with an iterative design that involves collecting data with MERs reasoning instruments and modeling complex systems. The research involved 1 model lecturer and 3 partner lecturers and 135 students who took part in the structure of plant development. The results of data analysis show the number of students who think complexly with MERs reasoning has increased by 48%, while the number of students who are able to model complex systems with good criteria has increased by 23%. Correlation test results between MERs reasoning performance with complex system modeling in general showed a positive relationship between 0.07 to 0.61. These evidences indicate that instructional learning has an effect on the progress of MERs reasoning performance as well as having an impact on the progress in achieving the ability of modeling complex systems, thus indicating instructional reasoning with MERs is effective for training systems thinking through modeling complex systems.

Abstract

Market waste is the second largest waste after household waste. Vegetable and fruit waste is the largest organic waste that comes from market waste. Various waste management efforts have been carried out by the government and the community, but have not completely resolved the waste problem. The purpose of this study was to determine the effect of market organic waste processing using an earthworm reactor (Lumbricus rubellus) with a modified Continuous Flow Bin method on cocoon production, biomass, and exmecat. This study used an experimental method with a completely randomized design (CRD), with three treatments of a continuous flow bin modified three types of mixed media materials to increase cocoon production, biomass, and exmecat quality. The results showed that the type of reactor had a significant effect (P ≤ 0.05) on cocoon production, the amount of biomass, biomass weight, broodstock mortality, exmecat production, media temperature, and media humidity, but had no effect on media pH. The use of reactor 2 (R2) with a mixture of 50% horse feces + 50% rice straw + feed 50 grams / day / nest box for market organic waste is the best reactor compared to reactor 1 (R1) and reactor 3 (R3). The amount of organic waste that can be processed by earthworms (Lumbricus rubellus) either as a medium or as feed is an average of 4.35 kg / nest box for 40 days of cultivation with a stocking density of 25 grams of earthworms / nest box. Based on the results of this study, it can be concluded that the ability of earthworms (Lumbricus rubellus) to process market organic waste using the modified Continuous Flow Bin method can reach 4.35 times their body weight / day. Thus, this waste processing method can be a complete solution to solving market organic waste management problems.
