Karakteristik Derivat Epidermis Daun Beringin (Ficus benjamina) dan Ketapang (Terminalia catappa) di Wilayah Kepadatan Kendaraan Berbeda dan Pemanfaatannya Sebagai Buku Ilmiah Populer

Abstract

Vehicle congestion generally occurs in large cities, one of which is in Jember Regency. From year to year the number of vehicles in Jember Regency has increased. The increase in the number of motorized vehicles has resulted in increased air pollution. Emissions produced by motorized vehicles will be absorbed by plants, until the plants experience morphological changes and physiological damage, especially in the leaves, especially in the epidermis (stomata and trichomes). The purpose of this study was to determine the differences in epidemic characteristics of banyan (Ficus benjamina) and ketapang (Terminalia catappa) leaves in places with dense vehicles and not dense vehicles. This type of research is descriptive qualitative. The research method begins with sampling, then sample preparation is done by the replica method, starting with cleaning both leaf surfaces, then applying clear cuticle, next attaching the isolation to the cuticle and then attaching it to the glass object, and observed under a microscope. Based on the results of the study, the stomata of banyan leaves have a parasitic type and glandular type trichomes. While the stomata of ketapang leaves have anisocytic type, ketapang leaf trichomes include glandular type. There are differences in data on the size and density of stomata and trichomes of banyan leaves and also ketapang. The results of the comparison of stomata and trichomes of banyan and ketapang leaves show that the ketapang plant has a glandular type. The results of the research were poured into a popular scientific book product which was then validated with an average score of 84% with valid/feasible criteria.
