Abstract

The mangrove ecosystem in the Sei Carang estuary waters, Tanjungpinang city is a mangrove ecosystem that has land conversion activities and leaves the environment with open land. The purpose of this study was to determine the density and regeneration rate of mangrove ecosystems on post-bauxite mining areas as seen from seedling, sapling, and trees. This research was conducted in July-October 2022. This study was conducted at four stations determined by the purposive sampling method, based on the existence of a mangrove ecosystem in which there are post-bauxite mine openings in the Sei Carang estuary waters, Tanjungpinang City. For each station, 3 plots of data were collected, with a plot size of 1x1m for the seedling category, a plot of 5x5m for sampling and a plot of 10x10m for trees. Data analysis used the formula for species density, for the regeneration rate by comparing the data from the calculation of the density of seedling, sapling and trees and then the formula for the diversity index. The results of the study found eight types of mangroves, namely Rhizophora apiculata, Rhizophora mucronata, Bruguiera gymnorhiza, Soneratia alba, Avicennia lanata, Nypa fruticans, and Lumnitzera litorea. Density values at station 1 for seedling 40,000 individual/Ha, sapling 2,667 individual/Ha, and trees 1,533 individual/Ha, at station 2 for seedling 30,000 individual/Ha, sapling 1,467 individual/Ha, and trees 500 individual/Ha, at station 3 for seedling 36,667 individual/Ha, sapling 5,200 individual/Ha, and trees 1,600 individual/Ha then at station 4 for seedling 53,333 individual/Ha, sapling 3,200 individual/Ha, and trees 2,133 individual/Ha. The level of mangrove regeneration at all observation stations is quite good.

Abstract

Fishing communities in South Sulawesi are known as Punggawa-Sawi. Numerous researches have shown that the partnership between punggawa-sawi is considered as an “exploitation”, judging from its profit-sharing system. Purse seine is a Tuna fishing vessel with 5 to 8 sawi and 1 punggawa. The focus of this study is to explain the fisherman’s preference of performing partnership with the punggawa and the values they implement between the work system. There are 8 groups of purse seine fisherman as the sample with a consideration that there were similarities in the pattern of working relationships and fishing activities. This research used qualitative approach and analyzed by descriptive correlation. The results showed that the recruitment of sawi by the punggawa was based on affinity (25%), experience (12,5%), needs for the ship operation (62,5%). The termination of the applicant can be caused by untruthfulness (50%), illness (12,5%), career change (37,5%). The compensation that is originally accepted by the sawi who quits, will be moved to the afflicted ones. The reasons to become sawi is (1) blood relative (20%), assurance of family economic sustainability (65%), and (3). Difficulty to find another job (15%). The profit-sharing system by the retainer is based on 3 reasons, i.e: (1), retainer investment (55%) (2), high risk (30%) and continuing the existing system (20%). Punggawa-sawi fishing communities have strength in the value of social relations that are built on the basis of shared needs (62.5%) and trust (37.5%). The existence of the punggawa-sawi is because of the social security provided to the retainer’s family (87.5%), both in the form of loans and assistance, and the personality of the retainer (12.5%).

Abstract

Coastal and small islands are faced with various significant challenges, one of which is the vulnerability to contamination by waste disposal from land and the magnitude of the impact it has on coastal waters. This study presents a framework for formulating environmental management of small island coastal waters from anthropogenic sources of terrestrial land with a system dynamic approach based on the characteristics of physical environmental factors and oceanography of the waters. The purpose of this research is to formulate a strategy for environmental management of the coastal waters of Tanjungpinang City. The results showed that the total magnitude of the waste load originating from anthropogenic sources on the mainland of Tanjungpinang City was 1,073.98 tons/year. The burden of organic waste in Tanjungpinang City is identified from five sources, namely domestic waste from residential areas, hotel and restaurant waste, the food industry, and the agricultural and livestock sectors. The Tanjungpinang coastal waters environmental management strategy with a dynamic system approach is recommended to use an optimistic scenario, but it needs to be supported by several policies in the form of (1) government support to build a community wastewater treatment facility or communal WWTP, (2) increasing community participation and concern for the aquatic environment , and (3) preparing regional strategic plans, specifically in the field of aquatic environmental management in the context of controlling effluent in coastal waters of small islands.

Abstract

The waters of the Sei Carang estuary are water areas that are influenced by tides and have mangrove vegetation along the waters. However, with the conversion of land functions such as bauxite mining and logging activities, the existing mangrove ecosystem is damaged. The purpose of the study was to determine the ecological characteristics of the mangrove ecosystem and to determine the level of ecological suitability of the mangrove ecosystem as a mangrove rehabilitation area in the Sei Carang estuary waters, Tanjungpinang City. This study used a purposive sampling method at 4 stations selected based on land openness and locations that allow for rehabilitation. Parameters in this study include mangrove type, substrate, salinity, tidal type, pH, current velocity, and biota objects. Based on observations, there were 10 types of mangroves found. The results of observations that have been calculated using the mangrove rehabilitation land suitability matrix show that each station can be said to be suitable for the rehabilitation area with the distribution of the suitability value of mangrove rehabilitation land showing a dominant suitability of S1 (Highly Appropriate).
