Abstract

Gastropods are invertebrate animals from the phylum Mollusca which have soft bodies and most of them have shells. The Pangpang Bay mangrove forest has a muddy substrate type and contains a lot of organic matter as a food source. This research was conducted in October - December 2022 at the Pangpang Ijen Geopark Bay. The area of the research area is about 900 meters2 with a total plot size of 1x1 m totaling 99 plots. The gastropod data collection method uses the systematic plot transect method. The recorded data contains the local name/type/type code, the number of species, and the number of individuals of each type. Data on abiotic environmental factors which include temperature, pH, and salinity are determined by the range of values and the type of substrate. Further data analysis was carried out by determining the species composition of gastropods by calculating the Shannon-Wiener (H') species diversity index. The results showed that there were 20 types of gastropods with members from 11 genus and 7 families. The results showed that the gastropod diversity index at the study site is in the medium category with a value of 1.95. The conclusion of this study is the diversity of species found in the mangrove forest of Pangpang Ijen Geopark Bay as many as 20 species. The value of diversity of gastropod species in the Pangpang Ijen Geopark Bay mangrove forest is in the moderate category because there are quite a lot of species found and only one species dominates.

Abstract

Conventional orchid cultivation is thought to be ineffective and time-consuming. Simple tissue culture procedures are insufficient to increase orchid quality. The need for ongoing development can be met by integrating different plant breeding strategies in orchid tissue culture, such as induction mutation, elicitor addition, and genetic transformation. The purpose of this article was to report on current improvements in the use of plant breeding techniques to orchid tissue culture to increase orchid quality. This article referenced significant scientific publications. Orchid tissue culture using mutation induction is used to develop improved variations. Giving elicitors can cause orchid plants to conserve themselves and become more resistant to diseases. The required transgene can be introduced into the genome of cultivated orchids via Agrobacterium. These advancements have the potential to revolutionize orchid cultivation.

Abstract

Fiddler crab (Uca spp.) belongs to the Order Decapoda and Family Ocypodidae, which live by making burrows in the substrate between mangrove plants. The presence of fiddler crabs plays an important role in mangrove ecosystems, which can increase sediment mineralisation due to burrows that can increase oxygen distribution into the sediment. This research was conducted in the mangrove ecosystem of Duta coastal, Probolinggo Regency. The method used when sampling biota in this study is the transect-plot method, which is used to place 1x1 m2 plots systematically along the transect. Sampling of fiddler crabs was carried out at the lowest low tide. Samples taken were fiddler crabs in the plot. Data on the species found, the number of individuals of each species, and the total number of individuals obtained from species composition were used to calculate species diversity. Fiddler crabs (Uca spp.) found in the mangrove ecosystem Duta coastal were 10 species, namely U. perplexa, U. rosea, U. vocans, U. annulipes, U. triangularis, U. coarctata, U. tetragonon, U. vomeris, U. forcipata, and U. dussumieri. The diversity value of fiddler crab species in the Ambassador Coastal Mangrove ecosystem is moderate (Hˈ = 2.209). All species of fiddler crabs were found in the muddy sand substrate type, because the burrow structure is strong, so that when the tide, the burrow condition is maintained.

Abstract

Lichen is an indicator plant that is sensitive to air pollution. This sensitivity is indicated by changes in state, body resistance, and reactions to environmental changes. This study aims to evaluate air quality in the University of Jember environment by using lichen as a bioindicator. The selection of the University of Jember as the research site was based on its unique environmental conditions, namely the presence of high motor vehicle activity, the presence of industry, and also the extent of green areas. Data were obtained through lichen sampling in 15 faculties and analyzed using the Air Quality Index of Atmospheric Purify (IAP). The results showed low average IAP values, indicating poor air quality in the campus environment. The Faculty of Computer Science and Faculty of Agriculture had the lowest IAP values, indicating the highest levels of pollution. Correlations between IAP values and the presence of green spaces and human activity showed that these factors significantly affected air quality. A decrease in lichen diversity indicates an increase in air pollutants, especially from vehicle exhaust. This study concludes that lichens can be an effective tool for monitoring air quality in urban environments, particularly in campus areas. Keyword: Air Quality, Bioindicators, Lichen, Pollution

Abstract

The Antirogo river, as one of the rivers across the Jember regency, East Java, plays an important role and is used for various activities such as agriculture, domestic, and industrial activities. These anthropogenic activities could affect the water quality of the river and the biota within. A group of river biota affected by anthropogenic activities is the benthic macroinvertebrates. Benthic macroinvertebrates can be used as bioindicators of river water quality. This study aimed to assess the water quality of the Antirogo River using the Shannon Wiener species diversity index (H') based on benthic macroinvertebrate data. Benthic macroinvertebrate sampling was conducted using a Surber net at three research stations. This research found 1703 individuals of benthic macroinvertebrates, which were classified into 16 families, 10 orders, and five classes. The most abundant family was the Heptageniidae, while the least abundant was the Simuliidae. The benthic macroinvertebrates' diversity index (H’) value was 1.67, with the evenness index (E) value at 0.60. Based on the diversity index (H’) value, the water quality in this river was lightly polluted with pollutants that can be in the form of solid materials and toxic compounds.

Abstract

The Biosite Pangpang Bay Ijen Geopark (BPBIG) has a high potential biodiversity value outside the conservation area, particularly in the mangrove forest. Namun informasi keragaman ini masih belum sepenuhnya lengkap. Sehingga penelitian ini bertujuan untuk menentukan keragaman jenis burung di hutan mangrove BPBIG. The research was conducted on October 2023 using the point count method at six observation points in the mangrove forest. Data analysis was carried out in two approaches, i.e., species composition and species diversity index using Shannon Wiener index (H’). We recorded 39 bird species, consisting of 32 genera and 21 families, in the mangrove forest of BPBIG. There is one bird species that has important conservation status based on the IUCN Red List and National Regulation, namely L. javanicus (a vulnerable and protected species). Furthermore, there are also three migratory birds (T. sanctus, N. phaeopus, and A. hypoleucos) that use the mangrove forest of BPBIG as stopover sites during migration periods. The results of the Shannon Wiener index showed that the bird diversity in the BPBIG mangrove ecosystem is in the medium category (H' = 2.02). Finally, based on these results, it can be concluded that the bird species in the mangrove forest of BPBIG are quite diverse.
