Abstract

This research was conducted in February 2021 in the waters of Pandan Island, West Sumatra Province. This study aims to determine the relationship between coral cover and the density of megabenthos found in the Pandan Island area. The method used in this study is a survey method. Coral cover data was collected using the LIT (Line Intercept Transect) method and megabenthos data was collected using the Benthos Belt Transect method. The results showed that Pandan Island had a good percentage of coral cover. The highest density of megabenthos was trokha snails found at each station, while the lowest density was Acanthaster planci which was only found at three stations and had a percentage of coral cover that had an influence on megabenthos density. Then it was also found that there was a strong negative relationship between coral cover and non-economic megabenthos, which indicated that there was an effect of the percentage of coral cover on both economic and non-economical megabenthos.

Abstract

With the development of the concept of utilizing natural resources with a supporting approach and environmental capacity, knowledge of the performance of ecosystem services is needed in planning the management of the Kampar Kir Production Forest Management Unit to ensure the sustainability of ecosystems that produce various ecosystem services needed for human life. This study aims to determine the condition of the carrying capacity and the carrying capacity of the environment in the Kampar Kiri forest management unit and the management block model that is formulated with an ecosystem services approach. This research belongs to naturalistic / qualitative research and the researcher does not treat it with analytical techniques using ArcGIS software. The research was conducted from July to December 2019. The results showed that the condition of the carrying capacity and carrying capacity of the forest area in KPH Kampar Kiri currently provides services for several types of ecosystem services which are considered as services that are relevant to the function of forest areas. Modeling of management blocks with the consideration of the Ecosystem Services approach provides a reference for 2 (two) types of management blocks in primary forests and 5 (five) types of management blocks in production forests. The area of each management block that is structured using an ecosystem services approach gives a different area variation from the existing blocks that are prepared using a natural resource grouping approach.

Abstract

Densitas zooxanthellae karang scleractinia Acropora aspera di perairan Pulau Mursala dan perairan Pulau Poncan Sumatra Utara telah diamati untuk melihat pengaruh turbiditas. Zooxanthellae sebagai simbion karang berbeda secara nyata antara dua lingkungan perairan yang berbeda yakni Perairan Mursala yang memiliki turbiditas lebih rendah secara signifikan dibandingkan dengan perairan Pulau Poncan. Karang scleractinia A. aspera di perairan Poncan memiliki densitas zooxanthellae lebih rendah secara nyata (P = 0,0000077) dari pada di perairan Mursala. Dari analisis regresi antara rerata harian turbiditas perairan dan densitas zooxanthellae A. aspera menunjukkan bahwa densitas zooxanthellae menurun secara signifikan dengan peningkatan kekeruhan. Pengaruh secara nyata kekeruhan perairan terhadap densitas zooxanthellae diperkirakan sebagai pengaruh kebutuhan micro algae akan cahaya dalam aktifitas fotosintesis.Kata kunci: karang, Acropora aspera, zooxanthellae, densitas, turbiditasThe effect of water turbidity on the density of zooxanthellae of scleractinian coral Acropora aspera at Mursala and Poncan waters North Sumatra were observed. Zooxanthellae as simbiont of coral was significantly different between that of two significant difference environments waters (Mursalah Waters had significant lower ofturbidity compare to Poncan waters). The scleractinian coral A. aspera in Poncan waters contained significanly lower (P < 0,5) density of zooxanthellae than Mursala waters. From regression analyses between mean of daily turbidity of waters and density of contained zooxanthellae in A. aspera revealed that density of zooxanthellae decrease significantly with increasing turbidity. The significant effect of turbidity of waters tothe zooxanthellae density was suggested as the effect of light requirement for micro algae in photosynthesis activity.Key words: Coral, Acropora aspera, zooxanthellae, density, turbidity
