Values in the partnership between retainer (Punggawa-Sawi) as a reinforcer in local community of purse seine fishermen in Luwu Regency
No full textFishing 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%)
Environmental management strategy for coastal waters through a dynamic system approach in Tanjungpinang City region, Riau Islands, Indonesia
No full textCoastal 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
The growth response and hepatosomatic index of milkfish (Chanos chanos Forsskal) fed with diet various levels carbohydrates in fermented of cow rumen liquid
No full textOne effort to reduce the role of protein as an energy source in feed is to maximize the use of feed carbohydrates as an energy source and engineering optimization of feed utilization can be done by adding exogenous digestive enzymes to feed. This study aims to determine the level of carbohydrates in the feed after being given cow rumen liquid which gives the best growth response and hepatosomatic index in milkfish. This study was designed using a completely randomized design (CRD) consisting of 4 treatments and 3 replications, Thus, there are 12 experimental units. The treatments were feeding with different levels of carbohydrate feed, namely 27,81; 39,50; 46,97 and 56,75% mixed with 80 mL of rumen liquid per 100 g of feed. Feed was given to juvenile milkfish measuring 7.19±0,036 g which was kept in a recirculating aquarium with a density of 15 fish/45 L of brackish water. The provision of various levels of carbohydrates in the feed had an effect (α0.05) on the hepatosomatic index of milkfish. Statistically, the best relative growth response and survival were found in fish fed with a carbohydrate-level feed treatment of 27,81; 39,50; 46,97%
Microplastic Contamination in Coastal Waters of South Larompong, Luwu, South Sulawesi, Indonesia
No full textMicroplastic contamination in the aquatic environment poses a serious threat to the survival of the ecosystem because it is persistent. This study aims to analyze the concentration of microplastics in the water column in the coastal waters of South Larompong. Sampling was carried out using the volume reduce method with the neuston net at four stations, namely Bonepute Beach, Ponnori Beach, Babana Beach and Damaci Beach. The results showed that there was microplastic contamination and found as many as 386 microplastic particles with an average concentration of 2.68 particles/m3. The results of the analysis of microplastic concentrations showed significant differences (P<0.05) between stations. The highest concentrations of microplastics are found on Bonepute Beach which is an area of aquaculture, fishing and densely populated settlements, then followed by Ponnori Beach which is a tourist area. Meanwhile, the lowest microplastic concentrations are found on Babana Beach, which is the estuary area of the Temboe River and Damaci Beach which is a nearby area. Several forms of microplastics were found, namely granules, fibers, films and fragments which were the most dominant forms. Several colors of microplastics were found, namely blue, brown, green, red, white, and black which were the most dominant colors. There are two types of polymer found, namely HDPE (High Density Polyethylene) and PVA (Polyvinyl alcohol). The conclusion of this study is that the coastal waters of South Larompong have been contaminated with microplastics so that more attention is needed regarding the handling of plastic waste, especially microplastics.
Punggawa authority and its Sawi compliance during the Covid-19 Pandemic (Case study on Beba Fishing Community, Takalar Regency)
No full textThe beating of fishermen due to the Covid-19 pandemic does not necessarily damage the Punggawa-Sawi relationship in Beba, Takalar Regency. The obedience of the Sawi people in choosing to stay with the Punggawa must be photographed from a different angle. This relationship can no longer be seen as a relationship of material interests, such as wages. The reason is, the acquisition of material in their relationship in the midst of the pandemic has also fallen sharply. This study aims to identify Punggawa authority and Sawi compliance that can still exist despite being hit by the Covid-19 pandemic and unfavourable conditions. This study uses a qualitative method with case study analysis. Data sources are divided into two categories, namely primary and secondary sources. Data was collected by using in-depth interviews, observation and documentation techniques. Specifically and tactically, the data analysis technique was carried out following the Miles and Huberman model by reducing data, presenting data and drawing conclusions. The results of this study indicate that the Punggawa authority which is woven into the Punggawa-Sawi relationship in Beba is obtained traditionally. They are not bound by a set of officially announced rules. Sawi's obedience to the retainer was not solely due to material interests. However, their obedience is based more on the characterization of Punggawa because of his generosity and the existence of a familial or kinship relationship between Punggawa and Sawi. This condition makes the relationship between Punggawa and Sawi very close so that it does not waver even in the midst of the Covid-19 pandemic

Concentration, distribution, and characteristics of microplastic in estuary, coast and marine organisms in Indonesia: A Preliminary Review
No full textThere is a rising concern regarding the accumulation of microplastics (MPs) in the aquatic ecosystems. Monitoring effort is crucial to understand the concentration and distribution of MPs. The objective of this paper is to mapping the concentration and characteristics of MPs distributed/deposited in estuary, coast, sediment, and marine organism in Indonesia based on data published from the last five years. In the estuary and coast, the highest MPs concentration were located in Brantas River, East Java, around 133 - 5467 particles/m3. In sediment, the highly amount of MP’s, 1136 particles/kg, were found in Kawal village, Bintan Island, Riau. In marine organism, horn snail (Telescopium telescopium) from Rambut Island, Jakarta Bay contained the highest amount of MP’s around 764.81 particles/individual . MPs were commonly found in fragments, fibers, and films with size ranging between 1 μm - 5 mm. Those MPs are mostly made of polyethylene (PE), polypropylene (PP), polystyrene (PS) and polyesters (PES). The data summary obtained in this study could be useful for understanding the sources of MPs as well as monitoring the environmental condition in the aquatic ecosystems
Ecological suitability of mangrove ecosystems as mangrove rehabilitation areas in the Sei Carang estuary waters of Tanjungpinang City
No full textThe 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)
