Abstract

The objective of this study was to determine the diversity of fish species found in Tumpang Valley, Tumpang Sub-district, Malang Regency, East Java as an effort to preserve fish species. The method used in this research is observation in various ponds by using the help of reflection book and google lens to identify the types of fish found. Based on the results of research conducted by researchers on the diversity of fish species in Tumpang Resort Valley Area, Tumpang District, Malang Regency, the results indiccate that there are 5 species, namely koi fish, Javanese wader fish (tawes), tilapia fish, citul fish, and goldfish. There are various types of koi fish with different genetic variations, but there are 8 koi fish that can be identified by researchers, namely platinum koi fish, orenji ogon koi fish, karasugoi koi fish, kigoi koi fish, yamato nishiki koi fish, nezu ogon koi fish, silver koi fish, and sanke koi fish. The result of the fish diversity index obtained is 1.173 (in the low category).

Abstract

: Background-Low levels of problem-solving and collaboration skills among junior high school students remain a significant challenge in science learning, particularly due to limited interactive and contextual learning approaches. Objective-This study aims to analyze the potential of integrating role playing into problem-based learning (PBL-RP) to improve junior high school students' problem-solving skills (PSS) and collaboration skills (CS). Method-The research method used was a quasi-experimental design with a non-equivalent control group, involving two classes: an experimental class using the PBL-RP model and a control class using the PBL model. Results-The results showed that the application of PBL-RP was effective in improving students' PSS with a moderate N-gain score, while the PBL class only achieved a low score. The highest indicator of improvement was in the aspect of understanding problems. In addition, student CS in the experimental class increased significantly based on the results of teacher observations, but the increase was not seen in peer assessments due to differences in perception and depth of observation. Conclusion-Overall, the results of the study confirm that PBL-RP has the potential to simultaneously strengthen students' higher-order thinking and collaborative skills and is relevant to 21st-century learning to foster contextual, reflective, and student-centered learning processes.
