Abstract

Density of Macroalgae Species on Pasir Panjang Beach, Kupang City Macroalgae have an important role for productivity and protection for other marine biota, namely as primary producers, carbon sinks, cosmetic ingredients and have economic value in the trade sector. Pasir Panjang Beach has a high aesthetic value, so it is used as a recreational space for the city community and as a destination for the development of tourist attractions. This study aims to determine the types and density of macroalgae in Pasir Panjang Beach, Kupang City. This study uses the line transect method with quadrant sampling technique with a size of 1m x 1m. The sample consisted of 100 plots of 10 transects at 2 stations. The samples were analyzed quantitatively descriptively to determine the morphological characteristics of the species and the density analysis of each species. The results found 15 types of macroalgae were divided into 3 divisions, namely the Chlorophyta division (7 species), Rhodophyta division (6 species, and Phaeophyta division (2 species). The highest species density at station 1 was Hypnea sp (33.38 ind/m2) and the lowest namely the species Acantopora spicifera (0.02 ind/m2), while at station 2, the highest density was Gracilaria salicornia (6.06 ind/m2) and the lowest density was Neomeris dumentosa (0.14 ind/m2). The conclusions are 1) There are 15 types of macroalgae from 3 divisions namely Chlorophyta, Rhodophyta and Phaeophyta, 2) The species density differs between stations.

Abstract

This study aims to determine the effect of the most effective volume of watering for Sargassum sp liquid organic fertilizer on the growth of red chili plants. The study was an experimental study using a completely randomized design with 5 treatments of watering volume of Sargassum sp liquid organic fertilizer, namely 0 mL (control), 50 mL, 100 mL, 150 mL, and 200 mL. Each treatment was repeated 4 times. The variables measured were plant height, number of leaves, and number of branches. Observational data were analyzed using analysis of variance and further tested by BNT. The results of the analysis of variance showed that the organic fertilizer treatment of Sargassum sp. very significant effect on the variables of plant height, number of leaves, and number of branches, where each variable shows the value of Fcount > Ftable. Further test results showed that the best treatment was Sargassum sp treatment with a watering volume of 200 mL/polybag.
