Background: The level of diversity has a crucial role in the stability of the ecosystem. The higher the variety, the more stable an ecosystem, including agricultural land cultivated by farmers. Increasing of population affected the higher demanding of community towards their consumption activities. Especially, the natural resources that comes from local area such as Sukamaju District. Biodiversity of resources urgently needed to preserve the ecosystems meanwhile being the potential source to fulfilled nourishment of the people. This study aims to determine the diversity of peatland ecosystems by using a purposive sampling method in every selection of subject groups based on the characteristics or characteristics of a specific population. Methods: Field and Laboratory activities are needed in this research. Sample collection using several methods according to the targeted sample. Most of the sample using purposive sampling but also line intercept transect method. Fish sampling used a fishing gear called a gill net with a mesh size of 2-7 inches. The fish caught is placed in a labeled coolbox. Insect collection was running in the morning at 07.00-11.00 and in the afternoon at 3-5 pm (UTC+09:00). Sampling is held once a month for three months at predetermined coordinate points. Diversity was analyzed using Shannon-Wienner diversity, evenness index, dominance index and intensity on peatlands. Result: The results found seven orders and 30 families, with a total population of 1,231 individuals. The most dominant types of insects are the orders Coleoptera, Hemiptera and Lepidoptera. High diversity index (H'=3.021), high evenness index (E= 0.86243) and low dominance index (D=0.3101). Fish community structure obtained diversity index (H¢) included in the medium category, for uniformity values in the high class and dominance index values in the low sort. The dominant fish species found were Channa striata, Anabas testudineus, Lates calcalifer, Mugil cephalus, Plotosus papuensis and Toxotes chataerus, while Oreochromis niloticus, Oreochromis mossambicus, Hexanematichthys sagor and Megalops cyprinoides. While the types of molluscs found to have the highest abundance were Pila ampullacea, Pomacea canaliculata and Pilsbryoconcha exilis.

“…All sampling sites of RSA had similar species composition, so the similarity index was 1 for every pair of sites compared (Figure 3d). Meanwhile, the ants (Formicidae) are known as insect that are still abundant in arid ecosystems (MacKay 1991), hence their dominance will lower the family diversity index (Amarullah et al 2017;Floder and Hillebrand 2012). Therefore, according to Figures 3.A-C, SRA 2010 had the lowest diversity index (H'= 0.61) as well as lowest of evenness index (E=0.43), but the highest dominance index (0.71) due to the abundance of Formicidae (Table 1).…”

Abstract. Oktafitria D, Febriyantiningrum K, Jadid N, Nurfitria N, Rahmadani F, Amrullah A, Hidayati D. 2019. Assessment of reclamation success of former limestone quarries in Tuban, Indonesia, based on soil arthropod diversity and soil organic carbon content. Biodiversitas 20: 1743-1747. The reclamation for sustainable ecosystem in mined land, including revegetation, is an obligatory program stipulated by the Indonesian government. This study evaluated the ecological improvement of revegetated land at the reclamation sub-areas (RSAs) of former limestone quarries in Tuban, East Java, Indonesia. The RSAs were coded as RSA 2010, RSA 2014, and RSA 2016 which represented the initial year of revegetation as well as the reclamation soil-material, namely the rejected soil-products, topsoil, and spoils, respectively. Soil insects were collected from ten sampling plots at each RSA using pitfall traps. The data of arthropods were analyzed to describe the community structure by determining the Shannon Diversity Index (H’), Simpson’s index (D), Sorensen's similarity and Shannon evenness index (E). The soil organic carbon (SOC) content from the soil composites was analyzed according to the Walkley and Black method. The results showed that SOC value at RSA 2010 (1.851±0.38%) was higher than that at SRA 2014 (1.694±0.29%) and SRA 2016 (0.947±0.10%). There were 18 families found from eight orders of soil insects (Coleoptera, Diplura, Diptera, Entognatha, Hemiptera, Hymenoptera, Neuroptera, and Orthoptera) and one order from terrestrial crustacea i.e., Isopoda, family Tylidae. The ecological indices of RSA 2014 (H’=1.15; D=0.47; E=0.61) and RSA 2016 (H’=1,19; D=0.47; E=0.57) were higher than those of RSA 2010 (H’=0,61; D=0.71; E=0.43). The Pearson analysis indicated moderate negative correlation (r=0.55) between soil arthropod diversity index and SOC. The diversity of soil arthropods at reclaimed area indicated that the reclamation was successful. Based on the study, we recommend that reclamation is done using mine spoil or topsoil rather than rejected soil products.

“…The lowest herbivore population and spider abundance were found on synthetic insecticide sprayed rice, and they were significantly different from those of refugia-rice plots. Amarullah et al (2017), the abundance of arthropods in the ecosystem is influenced by the diversity of plant species that dominate an agricultural area. Afterward, Nelly et al (2017) also said that location affects the insect diversity index.…”

Abstract. Hervani D, Sari SP. 2022. The abundance of arthropods and natural enemies on two growth phases of hybrid corn, Solok District, Indonesia. Biodiversitas 23: 2966-2972. Solok District, West Sumatra, Indonesia is one of Indonesia's hybrid corn production regions. As yet, the study of arthropods is still limited. This study aimed to study the abundance and diversity of arthropods in the hybrid maize agroecosystem in Solok District, West Sumatra. The research was conducted from May to November 2020 in Tanah Garam Sub-district, Solok District. The sampling was carried out four times in two growth phases of hybrid corn: vegetative (the age of 20 and 40 days after planting/DAP) and the generative phase (the age of 60 and 80 DAP). The arthropod collection was conducted using a yellow trap and a modified vacuum technique. The identification process was carried out at the Insect Bioecology Laboratory, Andalas University. The study found two classes of arthropods in a hybrid cornfield in Solok District, namely Arachnida and Insecta. The Shannon-Weiner diversity index value (H') was 1.383, and the evenness index of species (J') was 0.997. A total of 2,927 individual arthropods, 80 families, 8 orders, and 3 classes, were recorded in the hybrid corn ecosystem in Solok District. Insect class (2,866 individuals) dominated the diversity of arthropods, where the majority of the arthropods found belong to groups of natural enemies such as predators and parasitoids. Conservation of natural enemies (predators and parasitoids) is one of the main factors in supporting the success of pests biologically, so the act of identifying natural enemies in an area is very important.
