Abstract

Mangroves is one of the producers of nutrients, one of which is nitrate in estuary waters. Nitrate content in waters naturally comes from weathering or decomposition of plants and the remains of dead organisms. This study aims to analyze the relationship between mangrove density and nitrate in the mangrove ecosystem on Manomadehe Island, South Jailolo, West Halmahera. Data collection was carried out from April to May 2022. Analysis of sediment samples was carried out at the LPPM Basic Laboratory, Khairun University. The data analysis method used is simple linear regression. The results of the analysis of the highest species density at ST3 were 4100 trees/ha-1 and the lowest was ST1 at 1900 trees/ha-1. The highest nitrate concentration was found at ST3 at 3.58 mg/kg and the lowest at ST1 at 0.83 mg/kg. The strong ridge pattern (r) between the variable density and the nitrate concentration was 88.90%. The regression coefficient of 1.8998 indicates that the density of species has a positive relationship with the average concentration of nitrate in the sediment, where every 1 unit decreases in the value of mangrove species density will affect the decrease in the average nitrate of -1.33812 units.

Abstract

Coconut crabs (Birgus latro) is a fishery resource that is only found in eastern Indonesia, and the waters of Ternate City are an area that has this potential.  This research aims to determine the size distribution and habitat characteristics of coconut crabs in Tomajiko, Hiri Island District. The data collection method consists of several stages, namely determining stations, distributing bait, catching coconut crabs, morphometric measurements, and observing environmental parameters. Determination of stations in this study was carried out based on topographic differences in Tomajiko (divided into two stations). Coconut crab catching uses the roaming survey method. The bait used is coconut meat that has been split into several parts and coconut meat that has been mashed. The morphometric dimensions measured were chest length (carapace length) and body weight. The habitat characteristics observed were the type and extent of vegetation, organic matter content and substrate texture, environmental parameter measurements (soil temperature, air humidity and soil pH). The results of the research showed that the coconut crabs caught at both stations had relatively the same length, but the largest weight was found at station 2. Habitat characteristics in Tomajiko, Hiri Island strongly support the survival of coconut crabs.
