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

The use of polybag in nursery had an impact on the environment due to the plastic bag waste. Beside carrying environmental pollution, the use of plastic polybag can damage plant root during planting time. This research aimed at making environmentally friendly biopot from the mix of palm oil fruit bunches and the second hand cardbox using organic adhesive. The experimental used completed random factorial design with three time repititions. The first factor was the PVAc (polyvinyl acetate), citrate acid + sucrose and tanin. The second factor was the mix composition of palm oil fruit bunches and second cardbox. The pulping process of empty palm oil fruit bunches produced yield by 90.95 % and second cardbox by 86,67 %. The test showed that biopot produced of value water content by 1,05-15,54 %, gramatur 0,22-0,41 g/cm2, water absorption 1,72 – 2,63%, expand of thickness 0,26 -  15,58 % and burst pressure by 5,33 – 36,67 Kg. Biopot is able to contribute of nitrogen nutrient by 0,440 – 1,080 %, phosphorus nutrient by 0,020 – 0,064 %, and calium nutrient by 0,008 – 0,056 %. The mix mechanism of nutrient in decomposition process. Fastest rate of it was 1 year 9 month and 9 days, while the longest was 2 years, 11 month and 5 days. The produce of biopot can mitigate polybag at 4.217 to to provide 1 billion seed.The treatment of material composition and adhesive types had significant influence on the biopot. From this research it can be concluded that the best formulation for biopot is the composition of 80 % oil palm empty fruit bunches and 20 % second cardbox with the use of tanin adhesive.

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

The Chaetodontidae family fish is an indicator species because it has a close relationship with coral reefs based on a strong preference for coral stone as the main component of coral reefs. The existence of these fish can be used as a guide to assess and monitor the condition of coral reefs. This study was conducted in March 2022. The purpose of this study was to determine the abundance of reef fish of the Chaetodontidae family in the waters of Talam Island, to determine the condition of life coral cover and the relationship between the abundance of the Chaetodontidae family and coral cover. The method used in this study is a survey method. Data collection on reef fish of chaetodontidae family was carried out using the Underwater Visual Census (UVC) method and coral reefs condition data collection was done using the Line Intercept Transect (LIT) method. The results showed that the abundance of Chaetodontidae ranged from 710 to 1,430 individuals/ha with an average of 1,110 individuals/ha. The highest abundance of 1,430 individuals/ha at station III with a depth of 6 meters, while the lowest abundance was station II with a depth of 8 meters which was 710 individuals/ha. The percentage of life coral cover at each station ranged from 47.70% - 56.98%, 42.60% - 54.40% and 56.68% - 69.08%. Based on these percentages, the average percentage of life coral cover is 54.74% (good category), and there is a very strong relationship between life coral cover and the abundance of the Chaetodontidae family.
