Assesment Condition Using Hemispherical Photography Method on Mangrove Ecosystem in Coastal Minaluli, North Mangoli Subdistrict, Sula Island Regency, North Maluku Province

Minaluli Village has the availability of mangrove ecosystem resources in coastal areas. The availability of evenly distributed mangrove ecosystems can have a direct impact on the community. Determination of mangrove status conducted previously using conventional methods such as transect quandrat and spot check. Hemispherical photography method is one of the new methods used and developed in Indonesia. The study was conducted in July 2018 in Minaluli Village, North Mangoli District, Sula Islands Regency. North Maluku Province. The research objective is to obtain information on the condition of the mangrove ecosystem using the Hemispherical photography method. The results of the study obtained measurements of environmental parameters showed that environmental ecological conditions support the existence of mangroves. Morphological identification was obtained as many as 8 species from 3 families. Station I found 82% mangrove cover presentation value, for station II found 77% cover presentation, at station III found a presentation found 78% while at station IV found a presentation of mangrove cover 72%. The total presentation of mangrove cover obtained in the solid category, based on the standard criteria for mangrove damage. The density of the mangrove ecosystem obtained shows high density at each station. Based on the standard criteria for damage, the density of mangroves in this location is in the medium to very dense category with a value range between 1,067-2,022 trees / ha. Important value index (INP) analysis of each type of mangrove found a range of values between 31.73-95.55 The highest value index of the highest species was found in the Rhizophora stylosa type with a value of 95.55% then Rhizophora apiculata with a value of 95.08%, Rhizophora mucronata namely 81.05%, Xylocarpus granatum is 45.68, Ceriops stagal with value of 40.83%, Sonneratia alba with a value of 36.27 and Bruguiera gymnorhiza 31.73%.

The Relationship

This research was conducted to determine the condition of the mangrove ecosystem based on its canopy cover and to determine the types of mollusks (Bivalves and Gastropods) associated with the Benoa Bay mangrove ecosystem. Hemispherical photography is a method for observing mangrove canopy cover and line transect method for mollusks. The composition of mangrove species found in the research location were five species, namely Rhizophora stylosa, Rhizophora mucronata, Rhizophora apiculata, Bruguiera gymnorrhiza, and Avicennia marina. The percentage of mangrove canopy cover in the Benoa Bay mangrove ecosystem is in a good category (average = 76.59%). There are eight types of mollusks found in the research location. There are two types of bivalves (Polymesoda bengalensis and Gafrarium pectinatum) and six types of gastropods (Nerita balteata, Nerita picea, Neritina turrita, Pila ampullacea, Cassidula aurisfelis, and Littoraria melanostoma). The relationship between the percentage of mangrove canopy cover and abundance of mollusks in the Benoa Bay mangrove ecosystem is very strong (r) of 0.920. The higher the percentage value of mangrove canopy cover, the higher the mollusks abundance.

Leaf Litter Production

Mangrove litter production is important in the displacement of organic matter from mangrove vegetation to water such as in the coast of West Muna Regency. However, one factor influencing it is the frequency of rainfall. This research, therefore, aims to determine the influence of the frequency of rainfall in mangrove ecosystem by obtaining data through the fractional wet weight. The results showed that the biomass fraction with the largest amount were Rhizophora mucronata, Rhizophora apiculata, and Sonneratia alba with of 31.59; 31.07; and 30.96%, respectively, while the lowest was Rhizophora stylosa, Bruguiera cylindrica, and Bruguiera gymnorrhiza with of 30.07; 30.10; and 31.95%, respectively. The species with the largest leaf litter production was Bruguiera cylindrica, with of 1.72 g.m-2.day-1 which occurred in April and the lowest was Rhizophora apiculata, 0.24 g.m-2.day-1 in August. The species with the largest leaf litter production was Bruguiera cylindrica, 1.96 g.m-2.day-1 which occurred in May and the lowest was Sonneratia alba, 0.29 g.m-2.day-1 in August. In addition, the species with the largest fruit litter production was Rhizophora apiculata, 1.76 g.m-2.day-1 in April and the lowest was Sonneratia alba, 0.32 g.m-2.day-1 in September. The total litter production was 18,75 g.m-2.day-1 consisted of 6,69 g.m2.day-1 leaf litter, 6,54 g.m-2.day-1 branch litter, and 5,52 g.m-2.day-1 fruit litter. The higher the frequency of the rain, the greater the litter production. Keywords: biomass fraction, seasonal litter production, West Muna Regency

The mangrove ecosystem has different density levels per location. It can be influenced by environmental factors or because of human assistance. This research was conducted in Tongke-tongke Village, Sinjai Regency and Pannikiang Island, Barru District. Observations were conducted on three groups, namely groups of trees, stakes, and seedlings. Tree group used plot size 10 m x 10 m, stakes group used plot size 5m x 5m, and the group of seedlings used plot size 1 m x 1m. The result of tree group density will be compared with the standard criteria of mangrove damage of the Minister of Environment to know the criteria and the level of density. The mangrove ecosystem in Tongke-tongke village is overgrown by Rhizophora mucronata and Avicennia sp. and is dominated by R. mucronata with very dense density. In the tree group, R. mucronata has a density of 8020 Ind Ha-1. The mangrove ecosystem in Pannikiang Island is overgrown with Rhizophora apiculata, Rhizophora stylosa, Sonneratia alba, Aegiceras floridum, Ceriops tagal, Avicennia sp., Excoearia agallocha, and Lumnitzera racemosa and has a rare and moderate density. In the tree group, the highest density in C. tagal with a density of 1270 Ind Ha-1 and indicated moderate density. Competition is always there in the ecosystem. The species of this ecosystem is fighting for space and nutrients. Therefore, competition can determine the density of plants in it.

The Wailukum Mangrove Ecosystem requires a community based environmental management strategy. The purpose of this study was to analyze the characteristics of mangrove roots and stems in medium tide zones, the dominance index of Teredo navalis L and environmental management strategies in the era of the COVID-19 pandemic. This type of research is a case study. The research location is divided into two points, namely in the North and South. Sampling using the line transect method. Root and stem samples were observed using the quadratic method. The results of this study found that there are three types of mangroves that live in the medium tide zone, namely Rhizophora mucronata (Lamk.) Rhizophora apiculata and Rhizophora stylosa Griff. Characteristics of roots and stems have gaps and brittle easily. The dominance index of Teredo navalis L on the roots and stems is in the low category with the index range 0.01-0.62. Strategies that need to be used for environmental management of mangroves in Wailukum, East Halmahera Regency, are to open employment opportunities for the community, organize socialization and training of silvofishery systems for workers, make regulations to control community-based mangrove use and monitor violations of mangrove management.
