Abstract

The absence of data related to Arthropoda classes other than the orders Lepidoptera and Odonata in Suranadi Nature Park raises the need for studies on these fauna. This study aims to analyze the soil arthropod community and its role in science lessons in primary and secondary schools. This descriptive research was carried out from May to December 2019. Samples were collected in three paths, namely the forest edge, the middle of the forest and the waterway using the pit fall trap method. The collected samples were identified to species taxon at the Biology Laboratory of the Faculty of Teacher Training and Education, Mataram University. To obtain data on species diversity, an analysis was carried out using the Shannon-Wiener equation. There are 33 species of soil arthropods found. They consist of 3 species from the order Blattodea, 2 species from the order Orthoptera, 4 species from Araneae, 11 species from the order Coleoptera, 10 species from the order Hymenoptera, 1 species each from the orders Homoptera, Tysanura and Diptera. The most abundant species is Platidema sp of the order Coleoptera. Based on the results of the analysis, the diversity index of soil Arthtopoda species in Suranadi Nature Park is 2,628. The qualitative analysis shows that there are 2 elementary and junior high school science topics that are suitable to be taught using the concept of soil arthropod diversity at Suranadi Nature Park.

Abstract

The beetle data in Suranadi Nature Park is still limited to species that move on the ground. This study aims to analyze: (1) the species richness of the arboreal beetle, and (2) its potential as a science learning resource in elementary schools. This type of research is descriptive research using a qualitative approach. Sampling was carried out on the type of habitat in Suranadi Nature Park, namely the forest area with rice fields and residential areas, air flow and the middle with a dense canopy. The collected samples were identified to determine the species. The richness of this species data is then analyzed qualitatively to determine its potential as a source of science learning in elementary schools. This is done by comparing the species richness data of beetles and elementary thematic books, then the topics are assessed according to their level. The results showed that the species richness of arboreal beetles in Suranadi Nature Park consisted of 19 species from 5 families. The species are Lema sp., Aulacophora similis, Aulacophora quadrimaculata, Aulocophora sp.1, Aulocophora sp.2, Aulocophora sp.3, Aulocophora sp.4, Aulocophora sp.5 Parchicola sp., Podontia sp., Altica cyanea and Lilioceris sp. (family Chrysomelidae), Mimela sp., Mimela langbianica (Rutelidae), Exopholis hypoleuca, Ontophagus taurus, Protaetia fruhstorferi (Scarabaeidae) and Leptura sp. (family Cerambycidae). This arboreal beetle species data may be used as a source for elementary science learning on 33 sub-themes. Of this number, there are two sub-themes that have very appropriate categories, namely Sub-theme 2 The diversity of living things in my environment and Sub-theme 1 Components of the ecosystem.

Abstract

Kale land is a short-lived plant, containing the nutrients needed by the human body. The growth of kale land is influenced by various factors, one of which is the adequate supply of nutrients needed by plants. Fertilization is one of the efforts that can be done to ensure the availability of nutrients on agricultural land. Research has been carried out on the growth response of kale land due to the application of vermicompost and NPK fertilizers. The purpose of this research is to obtain information about (1) increased growth of  kale land due to the application of vermicompost, (2) increased growth of kale land due to application of NPK fertilizer, (3) increased growth of  kale land  due to the interaction of vermicompost and NPK fertilizer treatments. The research was carried out using an experimental method in the form of factorial arranged according to a completely randomized design. The first factor is vermicompost (C) with doses of 0 kg, 0.4 kg, 0.8 kg, 1.2 kg and 1.6 kg vermicompost per square meter of agricultural land. The second factor is the application of NPK fertilizer (P) at a dose of 0 g, 0.5 g, 1 g, 1.5 g per plant. Thus there were 20 treatment combinations and each combination was carried out with 3 replications. The growth parameters observed were plant height, total leaf, leaf length, leaf width and stem diameter of land kale. Research data were analyzed by Anova. The conclusions of the study were: (1) The application of vermicompost could increase plant height, number of leaves, leaf length and leaf width but could not increase stem diameter of kale land (2) application of NPK fertilizer can improve all growth parameters of kale land kangkong. (3) The interaction of vermicompost and NPK fertilizer cannot increase the growth of kale land.

Abstract

Kerandangan Nature Reserve is an area with important ecological aspects in the fields of economy, culture and education. One of its ecological components is amphibians. Previous research was conducted with brief observations so that the data were not sufficient to provide an overview of community fluctuations due to dependent and independent density factors. The study aim is to analyze the dynamics of the amphibian community during the period 2013 - 2019. The field survey was conducted in 3 different years, namely 2013, 2016, and 2019. Analysis of community dynamics was carried out by comparing the composition and species diversity indexes. Whether or not there are differences in the amphibian community is determined by One Way ANOVA. We found that during the period 2013-2019 there was a change in species composition. However, when compared with the results of research in 2011, the species composition is same as the data for 2019. Species richness is relatively stable unless there is a change in data for 2013 and 2016 with the discovery of Ingerophrynus biporcatus and Kaloula baleata so that the species richness increases to 4. The results of the One Way ANOVA test showed that there was no significant difference in diversity (p > 0.05) during the 2013-2019 timeframe.

Abstract

Dragonfly is a family of insects that are closely related to water. During their life cycle, especially when laying eggs and at the stage of dragonfly nymphs, they spend their lives in healthy water areas because dragonfly nymphs are very sensitive to polluted water quality. Therefore, dragonflies have an important role for the sustainability of the ecosystem, namely acting as predators and indicators of environmental pollution. The high diversity of dragonflies in an area indicates that the area is still not polluted because the environment supports the life of dragonflies. This study aims to determine the diversity of dragonflies (odonata) in the Joben Resort area of ​​East Lombok. This research is an exploratory descriptive study conducted from November to December 2021. Data collection was carried out 4 times and was repeated within 1 month in the morning and evening (08.00-17.00 WITA). The method used is a survey method with a sweeping net technique following a 500 m research path on 3 research paths, namely lane 1 (the river that borders Joben Ecopark), lane 2 (the path leading to the Resort Office and Joben Ecopark) and lane 3 (the river that flows through Joben Ecopark). Bordered by rice fields and Kokok Joben Brain Baths). The calculation of the diversity index of dragonflies uses the Shannon-Wienner formula (H'). The results showed that the types of dragonflies (odonata) found in the Joben Resort Area consisted of 20 species with a total number of individuals found from 3 lanes as many as 864 individuals. The diversity index of dragonflies in the Joben Resort area of ​​East Lombok is 2,309. The conclusion is that the diversity of dragonflies in the Joben Resort area of ​​East Lombok is in the medium category.

Abstract

Water hyacinth (Eichhornia crassipes) is one of Indonesia's wild plants which is considered a weed because of its rapid growth that can cause environmental problems. Generally, water hyacinth control is carried out physically/conventionally by throwing it away or burning it, causing new environmental problems. Water hyacinth has a high organic matter content, therefore water hyacinth can be used as an alternative feed to increase the production of earthworms. This study aims to determine the effect of adding water hyacinth as feed to increasing the production of earthworms (Lumbricus rubellus).This study aims to determine the effect of adding water hyacinth as feed to increasing the production of earthworms (Lumbricus rubellus).
