The present research was conducted to study seasonal limnological parameters and record composition pattern of aquatic macro-invertebrates of the Rampur Ghol. GRS-BIOS/ASPT index was used to calculate the water quality class, Shannon Weiner diversity index (H’) and Piélou evenness index (e) were used to determine taxa richness of the macroinvertebrates. Altogether 281 individuals of 14 families and 313 individuals of 18 families were recorded in dry season and rainy season, respectively. Similarly, diversity index and evenness index values were recorded 0.98 and 0.85 in dry season; 1.075 and 0.86 in rainy season. On the basis of different aquatic macro-invertebrates, GRS-BIOS/ASPT Index value of four sampling sites fall in class II (moderately polluted), four sampling sites belong to water quality class IIIII (critically polluted) and remaining two sampling sites belong to water quality class III (heavily polluted). Similarly, in rainy season seven sites fall in water quality class II (moderately polluted) and three sampling sites belong to water quality class II-III (critically polluted).Journal of Institute of Science and Technology, 2014, 19(2): 58-64

Plankton is organism that susceptible to environmental changes that used as indicator of environmental pollution by saprobic index because plankton has important role in affecting the water primary productivity. The research about plankton saprobic in Benoa Harbour is never done before. The aim of this research is to explain the structure of community and the level of plankton saprobic at Benoa Harbour. This research using random sampling method for determine the station. The result explained that there was 17 species of plankton in the waters of Benoa Harbor from two classes such as Bacillariophyceae, Dinophyceae on phytoplankton and from five classes such as Magnoliopsida, Malacostraca, Maxillopoda, Globothalamea and Hexanauplia on zooplankton. The total abundance of plankton ranges from 1.117.172 Individual / Liter- 1.626.163 Individual / Liter. The zooplankton diversity index in the waters of Benoa Harbor ranges from 1.06 to 1.58 and phytoplankton ranges from 1.02 to 155. This indicates that the value of diversity in all observation stations is categorized into low biodiversity. Zooplankton evenness index value in the waters of Benoa Harbor ranged from 0.73-0.88 and phytoplankton ranged from 0.71-0.96. This indicates that the index of evenness is relatively high. The dominant value of zooplankton in the waters of Benoa Harbor ranges from 0.24-0.43 and phytoplankton ranged from 0.22-0.41. This indicates that the dominance is relatively low. Saprobik Index (SI) value ranges from 1.0-1.6 and Tropic Saprobic Index (TSI) ranges from 1.76-1.96. This indicates that the waters of Benoa Harbour is categorized mild contaminated conditions until not contaminated.

Tambakrejo Village is an urban area located in the Jombang District. Tree vegetation continues to decline; one of the factors is the conversion of the function of yardland to residential areas. Changes in the land area will impact the structure of tree vegetation. This research was conducted by purposive sampling in 4 hamlets. Transects and species were included as random effects using the transect quadrat method (quadrat transect) by purposive sampling with tree size (10x10 m<sup>2</sup>). The data analysis was done qualitatively and quantitatively. Quantitative data analysis using vegetation analysis, namely: Importance Value Index (IVI), Dominance (C), and Diversity Index (Ĥ). Strata 3 tree vegetation H’ index in Tambakrejo Village, each hamlet is different, for Tambakberas Hamlet, H’ index value is 3.11%, Gedang Hamlet 2.97%, Nglungu Hamlet 2.91%, and for Petengan Hamlet 2, 89%. Most of the hamlets in Tambakrejo Village fall into medium-level diversity. INP index of Tambakberas Hamlet of 22.59% and lowest 2.07%. Gedang of 27.57% and lowest 2.84%, Nglungu of 19.76%, and lowest 2.86% Petengan of 28.79% and lowest 2.73%, The lowest Important Value Index is due to the transfer of the function of yard land for residential areas.

Wanagama Education Forest is the forest made by the ecosystem successions. Wanagama developed on barren hills located at Gunungkidul Province of Yogyakarta Special Region. The succession results providing a new habitat for the wild flora and fauna including soil arthropods. The soil arthropods having an important role in the ecosystem a detritivore etc. This study aimed to knowing soil arthropods diversity at Wanagama. The study conducted at Wanagama Education Forest in December 2017. The soil arthropods collected by six pitch fall trap that was spread at each collection point. Collected specimen by pitch fall trap method then identified and analyzed using diversity, evenness and dominance index. Based on the results, there is 25 family from 13 order of soil arthropods. Based on the data analysis diversity index results are H’=1, 53 and evenness index E=0, 47. The dominant individual is from Formicidae that playing a role as predators at Wanagama. Highest diversity is from Coleoptera order.

The study of butterfly in the in Air Dingin Landfills needs to be carried out to find out what types of butterflies are in this area and how their diversity is, given the increasing area of Landfills that will change the surrounding environment into a place of rubbish heap. The study was conducted by implementing survey method with insect net. The collection of butterflies was carried out in 2 periods (2x6 = 12 days) in April-June 2019 during sunny weather from 09:00 – 12:00 of Western Indonesian Time. All butterflies were collected at ±5 m distance from the collector. The data was analysed to calculate abundance, relative abundance, frequency of the presence of butterfly, and determine diversity was conducted by using the Shannon-Wiener Index and Evenness index. The results obtained 5 families, 14 genera, 22 species, and 220 individuals consisting of 122 males and 98 females. The diversity index value obtained was 2.27 and categorised as the medium category it is mostly because, as assumed, the environmental conditions of the Air Dingin Landfills were still in good condition.

The study of macrozoobenthos diversity in Way Sindalapai River can be used as one of the basic concepts in sustainable resource management in Liwa Botanical Garden area. Macrozoobenthos has an important role in the aquatic ecosystem, such as a food source for aquatic biota and as a detritivore. This study aims to determine the diversity of macrozoobenthos based on different sediment substrates in Way Sindalapai River, Liwa Botanical Garden, West Lampung. This study uses a purposive sampling method based on differences in the sediment substrates: muddy, sandy, rocky, and scrub with 3 replications. Sampling was carried out using a stratified filter and tweezers to separate the organism from the substrate. Samples were preserved in 70% alcohol and were identified by identification books at the Ecology Laboratory, FMIPA Universitas Lampung. The results of the study found 10 macrozoobenthos orders with a total of 155 individuals included in 13 families. The results of the calculation of diversity index values (H ') macrozoobenthos for all types of 2.26 (medium category). The highest macrozoobenthos dominance index (D) of the four substrates is in the rocky substrate that is 0.41 (low category). While the evenness index value (E) of macrozoobenthos in the Sindalapai Way River was 0.44 (medium category).

  Fish diversity in the Lakitan River is not well recorded, even though the data is important to add information about the diversity of freshwater fish in Indonesia. This study aims to study fish composition and ecological index in the Lakitan River. The study was conducted in the Lakitan River, Musi Rawas Regency, South Sumatra Province. The method used was the survey method. The direct sampling was done at 5 stations, the numbering of stations followed the direction of the river from upstream to downstream. The data at each station are tabulated based on species, family and order. Data analysis in-cludes a diversity index, evenness index, dominance index, and sim-ilarity index. The fish caught during the study were 418 individuals, which were identified into 20 species and 11 families. Barbonymus gonionotus is the most captured species in the Lakitan River. Cypri-nidae is the most captured family (9 species). The highest diversity index was found at station 5, with the number of fish collected was 16 species. The evenness index at 5 stations showed the equivalent species distribution and stable communities. The domination index at 5 stations were at, low category. The similarity index between sta-tions in Lakitan River which ranging from 0.65 – 0.97. These results indicate that fish diversity in the Lakitan River medium biodiversity.
