The Impact

Eleven billion microplastic particles are entangled in coral reef ecosystems in the Asia - Pacific Region. The presence of microplastics in coral reef ecosystems in Indonesia, especially in the Karimunjawa Marine National Park, was found as many as 22.7 and 12.8 particles / kilogram samples in two locations. The presence of microplastics in coral reef ecosystems allows threats to the health of coral reefs. Therefore, the importance of this study is to complement the data on the distribution of microplastics in the Karimunjawa Marine National Park as an initial step for conservation and mitigation of the impact of plastic/ microplastic pollution. Sampling using purposive sampling method. Sediment collection using SCUBA set and sediment grab at a depth of 3 - 5 meters. ± 1000 g of sediment was taken and stored in double zip lock plastic. The samples were then analyzed by microplastics in the Tropical Marine Biotechnology Laboratory, FPIK UNDIP. The results showed that the greatest abundance of microplastics was in the Karang Tengah area with the number of microplastics 96 particles / kilogram, and the farthest in the Ujung Gelam and Lego was 11 particles / kilogram. Research shows that the abundance of microplastics in areas with human activities such as tourism, ports, and boat routes has a high abundance compared to conservation areas or areas with little human activity. It is hoped that the available data from this type of research will be able to produce decisions on conservation measures in Karimunjawa Marine National Park.  Sebelas miliar partikel mikroplastik terjerat pada ekosistem terumbu karang di Kawasan Asia – Pasifik. Keberadaan mikroplastik pada ekosistem terumbu karang di Indonesia, khususnya di Taman Nasional Laut Karimunjawa, ditemukan sebanyak 22,7 dan 12,8  partikel/kilogram sampel di dua lokasi. Keberadaan mikroplastik di ekosistem terumbu karang memungkinkan adanya ancaman terhadap kesehatan terumbu karang. Oleh karena itu pentingnya penelitian ini untuk melengkapi data sebaran mikroplastik di Kawasan Taman Nasional Laut Karimunjawa sebagai langkah awal konservasi dan mitigasi dari dampak polusi plastik/mikroplastik. Pengambilan sampel menggunakan metode purposive sampling. Pengambilan sedimen menggunakan SCUBA set dan sediment grab pada kedalaman 3 – 5 meter. Sedimen diambil ± 1000 gr dan disimpan dalam plastik double zip lock. Sampel kemudian dianalisis mikroplastik di laboratorium Tropical Marine Biotechnology, FPIK UNDIP. Hasil menunjukkan bahwa kelimpahan mikroplastik terbesar pada daerah karang tengah dengan jumlah mikroplastik 96 partikel/kilogram, dan terkecil pada perairan ujung gelam dan lego yaitu sebanyak 11 partikel/kilogram. Penelitian menunjukkan bahwa kelimpahan mikroplastik didaerah dengan aktivitas manusia seperti pariwisata, pelabuhan, dan jalur kapal memiliki kelimpahan tinggi dibanding dengan daerah konservasi atau daerah dengan aktivitas manusia yang kecil. diharapkan dengan data yang tersedia dari penelitian sejenis ini, mampu menghasilkan keputusan terhadap langkah konservasi di Taman Nasional Laut Karimunjawa.

Non-timber forest products were potential assets to generate foreign exchange. Some types of which had good prospects and were in demand in the world of trade were rattan, gondorukem, eucalyptus and cassava. The purpose of this study was to determine the rattan types diversity in Rompo Village, Lore Lindu National Park. The study was conducted in December 2018 to March 2019. This research used the "survey" method by making a plot measuring 20 m x 20 m along to 1000 m. The distance between one track to another was to 200 m. The results showed that the type of Lambang Rattan (Calamus ornatus var celebicus Becc) had the highest density of 563.75 individuals/ha, then Pai Rattan (Calamus koordersianus Becc) 229 individuals/ha, Batang Rattan (Calamus zollingeri Becc) 183 individuals/ha, Ibo Rattan (Calamus ahlidurii) 52 individuals/ha, Rattan Tohiti Botol (Calamus sp) 46.25 individuals/ha, Pute Rattan (Calamus leiocaulis Becc ex. Heyne) 11.75 individuals/ha, Karuku Rattan (Calamus macrosphaerica Becc) 10 individuals/ha and the smallest was the type of Tohiti Wulo Rattan (Calamus sp) 9.75 individuals/ha. Rattan which had the highest Importance Value Index was the Lambang Rattan (Calamus ornatus var celebicus Becc) with an Importance Value Index value of 72.14% while the rattan that had the lowest Importance Value Index was Tohiti Wulo Rattan (Calamus sp) with an INP value of 5.02%. The level of species diversity (H ') of the rattan types found in the research location was classified as moderate with an H value of 1.75. The higher the area where the rattan is grown, the fewer types of rattan that can grow and only small rattan can grow on high ground, especially Tohiti rattan and large rattan cannot be found any more like Lambang rattan.

In recent decades, coral reefs worldwide have been impacted annually by climate change and anthropogenic impacts. Marine parks are utilized to protect coral reef ecosystems and to ensure it is in sustainable use. In the present study, a 15-year change in coverage and composition of a hard coral community at Dongsha Atoll Marine National Park (DAMNP) was examined from 2005 to 2019. The reef has experienced several disturbances, including 11 typhoons and six coral bleaching events. A 34.39% decline in coral coverage had been recorded over the past 15 years in response to multiple and recurrent natural disturbances. The coral communities and functional ecology of the Dongsha Atoll changed during this period. The average dissimilarities in coral communities ranged from 55.38 to 59.02%. The dramatic decrease in the abundance of branching corals in addition to a slight increase in massive and encrusting corals suggest the habitat has simplified. The degraded coral reef communities represent a low resilience ecosystem, even though the DAMNP has been established. Without effective management, the coral reef ecosystem of the Dongsha Atoll may not persist due to repeated impacts from recurrent disturbances.

Karimunjawa is one of the main destinations that present underwater beauty that is quite popular. But due to increased tourism activities provide economic benefits but also have a negative impact on coral reef ecosystems so that prudent and sustainable management is needed, these characteristics are felt capable of being helped by remote sensing technology. The purpose of this research is to analyze the coral reef zoning for the development of ecotourism segmentation and the carrying capacity of coral reef ecosystems and to map the condition of coral reef ecosystems in the Karimunjawa National Park area through remote sensing technology. The method used in data collection uses a survey method which is divided into 2 types in-situ conducted on 19th April 2019 to 2nd May 2019 and ex-situ taken for 4 years for coral cover and 1 year for sea surface temperature. By using quantitative descriptive analysis, land suitability results are obtained based on the land suitability index approach and the percentage of coral cover in determining the mapping of ecotourism segmentation areas. The results of this research show that through in-situ approach, data collection in three stations on Sintok and Menjangan Kecil Islands has good coral cover while Cemara Besar is damaged. The appropriate Tourism Conformity Index value is on Menjangan Kecil Island while the other two stations are not so that the carrying capacity calculation is only done on the appropriate and very appropriate island. Inversely proportional through the analysis of the Scenic Beauty Estimation value, Cemara Besar Island which shows a high value while on the Menjangan Kecil Island the lowest. Spatial analysis shows that the fluctuation in sea surface temperature during one year is not too significant and is still limited to the optimum temperature range for coral growth so that it does not affect the conditions causing damage to coral reefs, called bleaching. Looking at the distribution of coral reefs via satellite, over the past 4 years shows an increase in dead coral cover leaving 6,752,802 m2 in 2019.

Holocene Foraminiferal fauna at the area of Phan Vinh island, Truong Sa archipelago is relatively abundant and diverse in both taxonomic composition and ecological characteristics. The initial research results have identified 69 species (excluding several ones unidentified) belonging to 42 genera, 25 families and 6 orders. Among them, the representatives of the genera of Calcarina, Amphistegina, Heterostegina, Elphidium, Amphisorus, Marginopora, Sorites, Parasorites, Peneroplis, Archaias, Siphonipheroides, Septotextularia are predominant. They characterized by the shallow, transparent and warm marine environments of the region of Truong Sa archipelago during Holocene. Some problems related to this fauna at the area of Phan Vinh island such as biodiversity of coral-reef ecosystems, stratigraphic and paleogeographical significances, and its role of reef - building are also mentioned in this article. In addition, for the modern Foraminifera in the world, today they are being used as ‘biomarkers’ (bioindicators) in assessing and monitoring environmental quality of coral reef ecosystems in particular and marine environment in general. In Vietnam, this method has not been applied, but in the future, this is one of the methods that should be concerned. In addition, in aquaculture the Foraminifera is also a source of nutrition that should not be ignored.
