Abstract

The purpose of this study is to obtain the value of density, frequency, mangrove cover and the mangrove importance index (INP Mangrove) The method used for belt transects. The quadratic transect method measures 10 m x 10 m (tree category), 5 m x 5 m (sapling category) and 2 m x 2 m (seedling category). The results found that the mangrove community in Serewe Bay, Lombok Island, West Nusa Tenggara. Tree strata are dominated by Sonneratia alba species, pole strata are dominated by Sonneratia alba species and the seedling strata are dominated by Pemphis acidula. This shows that the existence of these three types can be found in almost every plot / plot. The Importance Value Index (INP) of mangroves obtained is classified as moderate, this shows that mangroves in Serewe Bay, Lombok Island, West Nusa Tenggara have an important role for the coastal environment.

Abstract

This study aims to determine the morphological and anatomical description of lichen thalus growing in urban areas. Sampling using exploration method (Cruise Method) and lichen thalus sampling technique is done by Purposive Sampling. Lichen thalus sample preparation was done by Embedding method. The results of this study indicate that (1) The life of lichen in urban friends is influenced by several factors including temperature, humidity and air pollutants that correlate with the LoS index value in Surakarta City. (2) Two species were found, Parmelia sp and Dirinaria sp that have different morphology and anatomy, which is caused by the characteristics of lichen substrate and air quality in the area. (3) Dirinaria sp species found in all study sites proved that the species is tolerant to environmental stress and is a taxon that characterizes urban areas. (4) The level of LoS index value in Surakarta City is also one of the factors that cause changes in the anatomical structure of the lichen thalus, namely the upper cortex layer. Thus, the higher the LoS index value in a road section, the thicker the size of the cortex thickness of the lichen thalus growing on the substrate in Surakarta City.
