Macrozoobenthos are benthic animals commonly found in substrate-based ecosystems, such as mangrove forests. Their presence in mangrove ecosystems significantly influences the decomposition activities within the substrate or sediment layers. The aim of this study was to identify species composition, species density, community structure of macrozoobenthos, and their vertical distribution within sediments on mangrove ecosystem in Ternate City. The study was conducted from August to September 2021 using the line transect method, with macrozoobenthos samples collected through iron pipe corers. Data analysis included species density, species diversity, dominance index, evenness index, niche width, microhabitat niche overlap, and the relationship between macrozoobenthos density and depth. The results showed that the macrozoobenthos species composition consisted of two species (Uca spp. and Nereis spp.), with a total of 25 individuals. Species diversity within mangrove ecosystem was found to be low, with one dominant species and a relatively even distribution. The species with the broadest habitat niche was the worm (Nereis spp.), while significant microhabitat niche overlap occurred between the worm (Nereis spp.) and the crab (Uca spp.). Simple linear regression analysis indicated that substrate depth did not correlate with macrozoobenthos species density.Keywords:aquaticbenthoscoastalfaunaterrestrial

Giant prawns (Macrobrachium sp) are one of the freshwater aquaculture commodities that have high economic value (Murtidjo, 1992). The demand for giant prawns in Indonesia has only been met by 40% of all existing demand (Tambunan, 2009. The aim of the research was to analyze the abundance of giant prawns and the size distribution of giant prawns in Togafo Village, West Ternate District, Ternate City. The purposive sampling method was used in this research. Then the sampling points that had been determined using purposive sampling were marked with coordinates with the help of the Global Positioning System (GPS). For the research location, it was divided into 3 observation stations. First, the shrimp body length and weight were measured using calipers and analytical scales. Abundance relative = individual/trip and Distribution of length measurements and distribution of shrimp weight measurements can be grouped using the equation (Effendie, 1979) as follows: K = 1 + 3.3 log n. Note: K = Number of Interval Classes, n = Number of Observation Data, log = Logarithm. Based on the results, the highest abundance of giant prawns (Macrobrachium sp) is at station 3 with a value of 0.575 ind., station 1 is 0.336, the lowest is at station 2 with a value of 0.088 ind. Size Distribution The smallest ranges between 40.17-52.19 mm and the largest ranges between 105.25 – 117.27 mm.

Ecoprint is a term that comes from the words "eko", which means "ecosystem/nature", and "print", which means "print." The ecoprint printing method uses natural dyes to print flowers, twigs and leaves on fabric. This method begins by attaching mangrove leaves to cloth, then printing the leaves and stems on the cloth. The problems faced by community groups are the lack of public knowledge about the benefits of mangroves as a business opportunity, the lack of public knowledge about techniques for making mangrove leaf ecoprints. Mitra only knows that mangrove forests function to protect beaches from waves and the wood is used as firewood. Meanwhile, the use of mangroves as dyes for ecoprint products as tourist souvenir products and increasing business opportunities for the community is not yet known. The objectives of the PKM activity are: partners can find out about the benefits of mangroves as a business opportunity, apply appropriate technology in techniques for making ecoprints on mangrove leaves and obtain types of quality ecoprint product motifs that have high selling value. The training activity for making ecoprints by utilizing the potential of mangrove forest resources around the Ngusanlenge mangrove tourist attraction area went smoothly with high participant enthusiasm. Enthusiasm for the results of ecoprint products with a variety of patterns and motifs from the mangrove leaves used. PKM activities increase knowledge and improve the skills of the community and students in making ecoprints by utilizing the potential of mangrove forests and building community enthusiasm for entrepreneurship. The ecoprint products produced include bags, tablecloths, handkerchiefs and headscarves.

The level of fishing efficiency and capacity of a fishery provides a useful instrument for policymakers to design management and control the response of the fishing industry to management. For this reason, fishing efficiency and capacity measures must be applied appropriately depending on a particular fishery's management and specific characteristics (Espino et al., 2006). This study aims to determine the efficiency of fishing capacity in mini purse seine in Ternate City. This research uses a descriptive quantitative method, DEA (Data Envelopment Analysis), to measure the technical efficiency of production (fishing capacity)—efficiency analysis using Microsoft Excel supported by frontier add-ins. The mini purse seine units that became Decision Making Units (DMU) were 20 DMUs consisting of 11 DMUs in Rua village, and 9 DMUs in Moti sub-district, Ternate City. Load capacity, fishing trip, fuel volume, number of crew members, and engine capacity are input factors in this study, while average production volume is the output factor. The results showed that 13 mini purse seine business units (13 DMUs) in Ternate City were inefficient (<1) and 7 mini purse seine business units were efficient. Most of the mini purse seine fishing capacity in Ternate City showed an inefficient condition (<1). The inefficient condition is caused by the excessive use of inputs (fishing capacity). Potential improvements can be made by reducing the use of inputs to obtain maximum output. Trip catch, fuel volume, and number of crew are production inputs that can be improved for optimum output in mini purse seine fishing in Ternate City. This research contributes to understanding best practices in using mini purse seines while supporting efforts to achieve economic sustainability in the capture fisheries sector in Ternate City.
