Abstract

Insects are vertebrate animals classified in the phylum Arthropoda. Insects are one of the animals that are very numerous, one of which is in the insecta class, so the presence of insects really affects the ecosystem. This research aims to determine the food preferences of leaf beetles (Epilachna varivestis) and oteng- oteng (Aulacophora similis) from several types of Solanceae plants. The samples used in this research were the leaf beetle Epilachna varivestis and oteng-oteng (Aulacophora similis) and 5 types of Solanaceae plant leaves including cayenne pepper leaves, bird chili leaves, eggplant leaves, ciplukan leaves and takokak leaves. This observation was carried out to find out 1). How long does it take for the beetle to find its food? 2). Which type of leaf is eaten first and which type of leaf is eaten the most? 3). How long does it take for a beetle to eat this type of food? 4). Is there a switching of the beetle's eating pattern? Based on the results of observations made, the leaf beetle Epilachna sp apparently preferred cayenne pepper leaves (Capsicum frutescens) for 30 minutes slowly and stopped by the other four leaves but was not eaten by the leaf beetle, the same as the leaf beetle, Oteng-oteng (Aulacophora similis) only liked one leaf, namely preferring eggplant (Solanum melongena) leaves for 30 minutes slowly and stopped the other four leaves but the oteng-oteng didn't eat them.

Abstract

The research-based enrichment module is a teaching material designed from recent studies and aligned with relevant learning content. This module aims to enrich students’ knowledge, improve their critical thinking skills, and enhance their understanding of current scientific concepts. This study investigated the effectiveness of a research-based enrichment module on karamunting plant identification in improving students’ learning outcomes. An experimental design with a pretest-posttest control group was applied. The population included 157 Grade X students at SMK Pertanian Pembangunan Negeri Sembawa. Using cluster sampling, 30 students from Grade X ATP 1 (control) and 30 from Grade X ATP 2 (experimental) were selected. The experimental group used the enrichment module, while the control group did not use any additional learning materials. Data were collected through cognitive learning outcome tests and analysed using descriptive statistics and a paired sample t-test. Results showed the experimental group achieved a mean post-test score of 81.67, compared to 70.50 in the control group. The paired sample t-test indicated a significant effect (p = 0.000, p 0.05). Thus, the enrichment module on karamunting identification significantly improved students’ cognitive learning outcomes.
