Abstract

The abundance of phytoplankton and zooplankton have correlation with mangrove conditions in coastal area. The mangrove degradation give negative impact for abundance and diversity phytoplankton and zooplankton. The research aimed to analysis and construct prediction model of abundance and biodiversity of phytoplankton and zooplankton in mangrove ecosystem. The research used the transect method (to determine mangrove density), filtering method (to analyze abundance of phytoplankton and zoopankton) and statistical method (to develop estimation modeling of plankton abundance). The results showed that (1) the mangrove density between 250 trees/Ha - 1250 trees/Ha (2) the phytoplankton abundance were 10.675 Indv/L (in mangrove rarely) - 24.290 indv/ L (in mangrove high density), (3) the zooplankton abundance were 261 Indv/L (in mangrove rarely) -  2.204 indv/L (in mangrove high density) (4) The modelling analysis showed that (1) the phytoplankton abundance (y) = 0.0303 x2 - 22.059 x + 13004 and (2) the zooplankton abundance (y) = 0.0057x2 – 5.39 x + 1458.2, with x = mangrove densityKeywords: phytoplankton and zooplankton, mangrove density, abundance, estuary and lagoon

Abstract

The purpose of the study was to determine the optimal portfolio composition using the Single Index Model and Mean-variance Model methods, then the results of the two methods were compared. Data collection was carried out using secondary data from stocks that make up the IDX30 index for the 2013-2022 period. The research method is a comparative analysis of the returns and risks obtained from the Single Index Model portfolio then compared with the return and risk of the portfolio using the Mean-variance Model with 5 portfolio combinations. The comparison is carried out by comparing the coefficient of variance of each resulting portfolio composition. The comparison is carried out by comparing the coefficient of variance of each resulting portfolio composition. The analysis results show that the portfolio produced by the Mean-Variance Model has better returns and risks than the Single Index Model.
