Abundance of green algae in the intertidal zone of Karang Papak Coastal, West Java, Indonesia

Abstract

Abstract Green alge (Chlorophyta) is the one of macroalgae who have much function such as ecologically and economically that living in the intertidal zone. Several genera of Chlorophyta have been used by local society around coastal area of Karang Papak Coastal, West Java as local product, but the research about abundance of Chlorophyta in Karang Papak coastal was not yet understood. This research aims to study of abundance of green algae in the intertidal zone, Karang Papak Coastal, West Java, Indonesia. This study was conducted on November 2018 and collecting data were collected using ransect method and held in every week (following moon phase). The website of algaebase.org and macroalgae identification books was used to green algae identification and then the results was verified by professional researchers from Lembaga Ilmu Pengetahuan Indonesia (LIPI). Data analysis was performed by calculating the total individual of each type green algae. The results showed that green algae were found consist of 15 species and 6 genus. The highest abundance of green alga species is Ulva lactuta and the lowest one is Codium tomentosum. Its can be caused by environmental factors such as nutrition, temperate, seasonal and tides of seawater. This data can be used for complete data about Indonesian macroalgae and as suggestion for management and monitoring of macroalgae by government and local people to maintain the sustainability of Chlorophyta.
