Abstract

This study aims to determine the relationship between the physical and chemical factors of the waters (Temperature, Salinity, pH, Dissolved Oxygen) and the diversity of sea cucumbers (holothuroidae) in the coastal waters of Pia Hamlet. The method used is the Belt Transect method. Analysis of diversity data using the Shannon-Winner diversity index formula then to determine the functional relationship between sea cucumber diversity and physical and chemical factors of waters was carried out using simple linear regression and multiple linear regression. The results showed that 1 class, 2 orders, 2 families, 3 genera with 5 species, namely Holothuria atra, Holothuria leucopsilota, Holothuria scabra, Bohadschia argus and Synapta maculate. The diversity index value is low with an average value of 0.7214. The temperature measurement results ranged from 28.04°C-30.16°C. Salinity measurement results ranged from 31.21-32.26 ‰. The results of pH measurements ranged from 6.80-7.41. Dissolved oxygen measurement results ranged from 5.96-6.40 mg/L. The results of simple regression analysis showed that dissolved oxygen had a relationship and had a significant effect on sea cucumber diversity. The results of multiple regression analysis explained that salinity and dissolved oxygen, if tested together, had a strong relationship and had a significant effect on sea cucumber diversity.

Abstract

Coastal waters of Namtabung village sub-district Selaru West Southeastern Moluccas is the water areas that have all kinds of marine biota one of which is Holothuroidea. The coastal waters of Namtabung village are in good condition for the marine organisms lives. This research aims to know the specieses of Holothuroidea in Namtabung village sub-district Selaru West Southeastern Moluccas. Type of the research is descriptive qualitative, with procedures observation and identification. The results of this research there are eight species of Holothuroidea, among there are from Aspidochirotida order with 7 species consist of Holothuria scabra, Holothuria atra, Holothuria edulis, Holothuria leucospilota, Actinopyga lecanora, Stichopus ocellatus and Bohadschia argus, whereas from Apodida order there are only one species that is Synapta maculata

Abstract

Collembola are a good example of the diversity of soil animals and play an important role in nutrient cycling, organic matter decomposition and soil formation which are important parts of forest ecosystems. This research was conducted on cassava land and a vegetable garden in Waai village, Salahutu sub-district, Central Maluku district, on July 18 2020. This study aims to determine the abundance and diversity of the Collembola insect in shifting cultivation in Waai village, Salahutu sub-district, Central Maluku district and its relationship with environmental factors. Results The study obtained 3 families and 6 species with a total abundance of 12.2 individuals/m2. There are differences in the abundance of Collembola found in vegetable gardens and cassava fields. The abundance of Collembola found in the vegetable garden was 3.6 individuals consisting of 2 families and 2 species, while in cassava fields it was 8.6 individuals divided into 2 families and 4 species.
