Abstract

ABSTRACT: Microalgae is the most primitive cell-sized plant form known as the phytoplankton, where this phytoplankton is one of marine biota which has a vital role for a waters because as primary producer for water. Where in this study will be taken 3 stations, station 1 is close to the resident's house, the station 2 transport lines and station 3 is in the middle of the waters of Cemara Beach. The purpose of this study were (1) To know the species of microalgae species located on the beach Cemara. (2) To know the diversity, uniformity and dominance of microalgae at Cemara beach as the basis for the preparation of Cryptogamae Systematic practice manual. (3) To find out the results of research can be used as the basis for the preparation of Cryptogamae Systematic practice manual. The type of research used in this study is descriptive. The data obtained in this study is qualitative data analyzed descriptively. Calculated index of species diversity, uniformity, and dominance, using Shannon Wiener's formula. The results showed that (1) Indices of diversity of microalgae in Cemara Coast waters at each station, station I (2.19), station II (2.44), and station III (1.71) which means that the three stations have community moderate biota or moderately polluted water quality. (2) Uniformity index of microalgae at each station, station I (0,62), station II (0,69), station III (0,48) which means in all three stations have uniformity of organism in balance condition. (3) The dominant index of microalgae at each station is obtained an index of average dominance of 1, there are species that dominate other species or unstable community structure. The conclusion of this research is the diversity of microalgae in the waters of Pantai Cemara Desa Lembar Selatan Lembar subdistrict, West Lombok regency has index of medium contaminated diversity, uniformity index and unstable dominance index.

Abstract

ABSTRACT: The aims of this research is to analyze the structure of amphibian communities in natural park Kerandangan, and to describe the validity of animal ecology module that developed. The population of this research is all amphibians in natural park Kerandangan. The sample used in this research is the number of individuals amphibians (ordo anura) captured at the time of investigation. The method used is visual encounter survey (VES), and combined with capture sign release and recapture (CSRR). Data collection techniques used in this research were (1) basic data, (2) validation. Total 1 species of amphibians have been identified, that is families Bufonidae as many as 15 individuals. This research different from Kadir (2011) with ± 5 year periode in natural park Kerandangan have been declaine in community structure. The result of this research obtained from the calculation of data analysis as follows: (1) the diversity index (H = 0,186), (2) Simpson dominance index (C) = 0,0044, (3) the relative abundance is 6,7%, (4) density on 1 individual/100 m, (5), evenness index = 0,0686, (6) validation sheet with the calculation result of test readability by 20 four semesters graduate student, obtained average value = 3,66 with 73,1% level of achievement, the average from the material expert = 4,3 with 86% level of achievement, the average result from the appereance expert = 4,1, with 82% level of achievement, as well as the average value from the linguistics expert = 4, with 80% level of achievement, from the calculation based on expert judgment, can be declared that the module of animal ecology suitable for use a module.

Abstract

This research was aimed at analyzing the forest vegetation of National Parkin Rinjani Mountain for developing plant ecology practicum guide. This research was pure research with descriptive explorative design. This research was donein Resort Joben, Rinjani Mountain.The sample that were used in this research was taken based on the area by using area sampling technique. The data collection were analyzed by using Mullerand Dombois Ellenberg theories. Based on the analysis of the data collection, it was found that there were 44 plant sin 3 level sin individual class ifying which 34 type sofs take with KlokosUdang were dominated, 37 type sofmast with Lembokek were dominated and 23 type softree with Dadap were dominated. Based on the observation and analysis of the data in Resort Joben, Rinjani Mountain, it was found that 34 type sofs take with 238 units; 37 type sofmast with 166 units; and 23 type soft tree with 357 units, there fore the total number of regeneration level was 44 types with 761 units. The highest level of Important Value (IV) index was type sof mast which was 294.1. There sult of validity from practicum guides was shown that the mean score was 3.07 with good category. According to the finding sand discussion of this research, it can be concluded that there is some vegetation type sof National Parkin Resort Joben, Rinjani Mountain, and according to the result of practicum guide validity, it was shown that the result of this research was feasible and in good category
