Abstract

Mangrove ecosystems provide a variety of ecosystem services, including coastal protection, carbon sequestration, and opportunities for biodiversity. The mangrove ecosystem, which is an intermediate area between sea and land, has a sharp environmental characteristic gradient. The tides of seawater can cause large fluctuations in several environmental factors, especially temperature and salinity so that the animals that survive and thrive in the mangrove ecosystem are animals that have a great tolerance to extreme changes in environmental factors. This study aims to determine and identify the diversity of fauna species in the mangrove ecosystem. The survey location in this study is in the mangrove area of ​​Bungus Bay which is spread over 4 observation points, namely location 1 (Cindakir), location 2 (Kaluang Cove), location 3 (Kabung Labuhan Cino Cove), and location 4 (Pandan Cove) which is mangrove ecosystem as a sub-system of the coastal ecosystem. Based on the results of the field survey, there were no endemic species found in the protected zone on the coast of Bungus Bay. The fauna found in the mangrove ecosystem in the Bungus Bay area is divided into 2 (two) fauna characteristics, namely vertebrates consisting of 5 (five) species, namely aves (birds), reptiles, amphibians, mammals and primates and fish vertebrates. While invertebrates consist of Crustaceans or crabs, carideas or shrimp, molluscs, echinoderms, and polychaeta or worms. The results of the field survey showed that the types of species based on the family characteristics of the fauna found in the mangrove ecosystem at observation location 1 (Cindakir) were less than the number of species found at observation locations 2, 3 and 4 (Kaluang Cove, Kabung Labuhan Cino Cove, and Pandan Cove).

Abstract

Caught fish that have been processed into abon fish increase the sale value of fish. Increasing the selling value of fish and developing business opportunities can increase fishermen's household income and become one of the solutions to poverty in coastal regions. This study aims to analyze the factors that influence the production of the catch and income of traditional fishermen's fishing business. This study aims to analyze a dynamic system model of increasing fishermen's income through the abon fish processing industry in Pasie Nan Tigo Village, Koto Tangah Sub-district - Padang City. This study uses a dynamic systems modeling approach in analyzing the added value of abon fish processing. The results showed that in a scenario with a distribution proportion of 70%: 30%, the sales value of products that undergo processing (abon fish) is higher than raw fish sold without undergoing any processing. The ratio of the sales value between processed abon fish to raw fish sold without undergoing any processing is 115:100. This means that the same volume of fish processing (abon fish) has increased the sale value of raw fish by 15%. This sales value ratio will certainly increase fishermen's income.
