Abstract

Beautiful beetles are a group of insects that play an important role in maintaining ecosystem balance, ecotourism and education. Suranadi Nature Park, as one of the conservation areas in Indonesia, has great potential in maintaining the biodiversity of these insects. However, information on the dispersion pattern of beautiful beetle species in this area is still very limited so this research is important. The data collection method was carried out by survey, by capturing and directly documenting the beetles encountered during the exploration of the forest of TWA Suranadi. Data collection was carried out in June 2024 on the edge, middle of the forest and waterways. The samples obtained were brought to the Biology Education laboratory of FKIP Unram for identification. The results showed that the distribution pattern of beautiful beetles in Suranadi Nature Tourism Park has three distribution patterns, namely group distribution patterns of 21%, Uniform 72% and random distribution patterns 7%. In conclusion, the distribution pattern of beautiful insects in Suranadi Nature Park is different. The dominant uniform distribution pattern, then the group distribution pattern and the least random distribution pattern.

Abstract

Gili Kapal is a small island filled with sand. The sand on Gili Kapal is caused by coral fragments and shells of benthic Foraminifera which dominate. Foraminifera is a group of single-celled animals that belong to the Protozoa Phylum of the Class Sarcodina and can be used as bioindicators to determine various environmental changes in the ocean. This study aims to determine Foraminifera species and community structure in the form of species diversity index, species evenness index and dominance index of Foraminifera species in Gili Kapal, Sambalia, East Lombok. Sampling was carried out using a corer sampler made of PVC pipes with the Purposive Sampling method in January 2022. The species diversity index, species evenness index, and species dominance index were analyzed as part of the data for this study. According to the study's findings, there are five species across four genera and three families. Sequentially the Foraminifera species found were; Amphistegina radiata, Calcarina spengleri, Schlumbergerella neotetraedra, Schlumbergerella floresiana, and Sorites orbiculus. The species diversity index was 0.9 (low category), the species evenness index was 0.4 (low category), and the species dominance index was 0.6 (medium category). It can be concluded that, sequentially the constituents of the Foraminifera community on Gili Kapal are Amphistegina radiata, Calcarina spengleri, Schlumbergerella neotetraedra, Schlumbergerella floresiana, and Sorites orbiculus.

Abstract

The Bagek Kembar Essential Ecosystem Area (EEA) is one of the mangrove forest areas in Lombok Island. This mangrove forest area is managed and developed into an educational tourist attraction (Ecotourism) to know various types of mangroves. The existence of Bagek Kembar mangrove Ecotourism is very important to support the economic income of the surrounding community. The existence of these various activities will potentially affect the balance of the mangrove ecosystem and the biota that live in there. This study aims to determine the composition of phytoplankton species and the condition of their diversity in the waters of the Bagek Kembar Mangrove Essential Ecosystem Area, West Lombok. Descriptive exploratory research was the methodology used. A 20 µm plankton net was used to filter 100 L of water in order to sample phytoplankton. Formalin at a 4% concentration was then used to preserve the filtered water samples. Individual abundance, evenness, dominance, and the index of species diversity were computed in order to analyze the data. The findings revealed that there were five divisions and 84 phytoplankton species. The Bagek Kembar Mangrove Essential Ecosystem Area's waters had an average phytoplankton abundance of 2,770 ind/L. The species dominance index of phytoplankton was 0.192 (low category), the species evenness index of phytoplankton was 0.633 (evenly distributed), and the average phytoplankton species diversity index of 2.296 was categorized as moderate. According to the findings of this study, the phytoplankton community's stability in the waters of the Bagek Kembar Mangrove Essential Ecosystem Area fell into the medium range.

Abstract

One of Indonesia’s biodiversity components is the insect group. Insects (Insecta) represent the largest group of animals, accounting for about one-quarter of all known animal species on Earth. Among them, beetles and butterflies are the most diverse, largely influenced by the availability of host plants as an energy source. This study aimed to determine the diversity, dominance, and evenness of butterfly species in Narmada Park, West Lombok Regency, and to explore their potential as enrichment material for Animal Ecology practicum. The research was conducted at two observation sites one dominated by flowering plants and the other by trees using a survey method with purposive sampling and a sweeping net technique. The results recorded 122 butterfly individuals comprising 13 species from four families: Nymphalidae, Lycaenidae, Papilionidae, and Pieridae. The Shannon-Wiener diversity index (H’) was 2.50937 (moderate category), Simpson’s dominance index (D) was 0.085595, and Pielou’s evenness index (E) was 0.978331. The measured environmental factors included temperature (31.7°C), humidity (67.5%), and light intensity (385 Cd). The moderate diversity and high evenness indicate a relatively stable habitat condition that supports the existence of butterflies in the area.
