Abstract

Lebak Petai is a place for fishing by fishermen and auction holders. A continuous fishing system can affect the diversity of fish in these waters. The aims of this research was to identify the type of fish, length and weight of the fish, analyze the species diversity index, uniformity index, relative abundance, dominance and water quality. This research was carried out from July to September 2021. Sampling took place in Lebak Petai, Pedamaran sub-district, Ogan Komering Ilir district, using three sampling stations. The results of the research showed that there were 530 types of fish caught in Lebak Petai, consisting of 13 types of fish belonging to 9 families. The largest fish in length and weight was the Barbonymus schwanenfeldii fish, namely 12-25.5 in length and 21.11- 188.92 in weight, while the lowest fish was the Elops mchnata fish, namely 9-10.5 in length and 5.58-8.5 in weight. The diversity index was classified as medium, namely 2.33-2.51, the uniformity index was classified as uneven, namely 0.92-0.98, the highest relative abundance in Lebak Petai is Trichogaster pectoralis, and there was no dominant fish, namely between 0.9-0.11. The water quality during the research in Lebak Petai, Ogan Komering Ilir Regency was still within a suitable range for fish life.

Abstract

This study aims to improve the cognitive abilities of third-grade elementary school students through the implementation of the Teaching at the Right Level (TaRL) approach in the subject of Natural and Social Sciences (IPAS). The background of this research is the low cognitive achievement of students due to instructional strategies that are not aligned with their level of understanding. The research was conducted as a Classroom Action Research (CAR) using the Kemmis and McTaggart model over two cycles, involving 28 students at SDN Julang, Bogor City. Data were collected through observations and cognitive achievement tests, analyzed both quantitatively and qualitatively. The results showed a significant improvement in student learning outcomes. The percentage of students achieving mastery increased from 35.71% in the pre-cycle to 64.29% in the first cycle and reached 89.29% in the second cycle. The average score also increased from 61.07 (pre-cycle) to 77.86 (cycle II). The implementation of TaRL, supported by ability-based grouping, tiered LKPD, visual media, and interactive educational games through Wordwall, proved effective in creating a more contextual, enjoyable, and meaningful learning experience. Therefore, TaRL can be considered an adaptive and inclusive learning strategy to enhance cognitive development in IPAS learning at the elementary level.
