Abstract

Mangroves are a habitat for mangrove crabs, one of which is Scylla olivacea, which is a source of protein and has nutritional value and is a food commodity whose selling value increases every year. The aim of this research was to determine crab density, crab growth patterns and physical and chemical condition parameters. Determining the location of the station used purposive sampling at 3 observation research locations, at each observation location 10 traps were placed. The data analysis used is data on crab density, growth patterns and environmental physico-chemical factors. This research was conducted in August 2023. There were 18 Scylla olivacea crabs that were obtained at station 1, 6 (3 males, 3 females), station 2, 5 (1 female, 4 males), station 3, 7 (3 male, 4 female), with a density value of 1800 ind/ha. The growth pattern for male mud crabs is W = 0.0202x + L5.9649 with a value for females of W = 0.0243x L+5.8572, while at all observation stations W= 0.0191x+L 6.2536. So the growth pattern of Scylla olivacea is negative allometric. Environmental parameter data consists of temperature, salinity and pH. At salinity 10 0/00 - 20 0/00 and temperature ranging from 24 0 C- 27 0 C, pH ranges from 7.1-7.3.

Abstract

Abstract: One form of utilization of aquatic resources is mangrove forest vegetation. The potential of mangroves in Indonesia is very large because it has several types of mangroves that thrive. Pedada fruit (Sonneratia caseolaris) is one type of mangrove fruit that grows abundantly throughout the coastal areas of Langsa-Aceh. The business of processing mangroves into food products has not been widely developed and is of interest to coastal communities. One of the processed foods made from jam can be made from the heating process of a mixture of fruit pulp and sugar. Pedada fruit can be processed into a healthy jam by reducing sugar in the processing process which is replaced with stevia. The process of making jam from pedada fruit (Sonneratia caseolaris) with the addition of stevia sweetener begins with cleaning the material, namely pedada fruit. The next process is mixing the pulp of the pedada fruit and adding stevia sugar, then the heating, thickening and cooling process is carried out. The process ends with packaging. The production of healthy jam from pedada fruit can improve the economy of the community. Therefore, the PKM Team of Samudra University wanted to help the economy of Biruen residents by making education on processing pedada fruit into healthy jam. The hope is that the pedada fruit jam product can become a new business for the community and can increase the UMKM of the Bireum community. This is the background for the PKM Team of Samudra University to create education on making healthy jam with the addition of stevia. Keywords: community service, healty jam, pedada fruit, stevia

Abstract

Seruway is one of the sub-districts in Aceh Tamiang, which is located in the coastal area. This coastal area is dominated by mangrove species, where the mangrove area is used as a habitat for aquatic biota animals, one of which is gastropods. Gastropods are soft-bodied animals that have threaded shells. This research aims to determine the value of the species diversity index and distribution patterns of gastropods in Kupang Beach, Seruway District. This research is a type of quantitative descriptive research with sampling using a survey method. Sampling was taken using transects. Sampling was divided into 3 stations, namely the first station in the mangrove area, the second station in the beach area and the third station in the pond area. Each station consists of 4 transects measuring 50 meters, each transect has 4 plots measuring 10x10m. Samples that are obtained will be identified using an identification book. The research results showed that the number of gastropod species found was 17 species from 9 families with a total diversity index value at the research location, namely H'= 2.405, which is classified as medium. The distribution pattern of gastropods on Kupang Beach falls into two categories, namely the uniform category 59% and the undefined category 41%.
