Abstract

Alien crayfish species (Cherax quadricarinatus and Procambarus clarkii) have been found in some Indonesian area and demonstrated invasive species characters. Despite of their economy benefit the crayfish has potential ecologically disadvantage to be valuated. This study aimed to develop valuation method to estimate economical loss due to alien invasive species on food competition basis in an aquatic ecosystem. This approach was conducted by estimating the potential loss due food competition between invasive species and its inferior competitor. The case study was carried out in the Lido Lake and in an aquaculture site at Cisaat, Sukabumi – West Java. The research results that economic loss due to the disappearance of native Macrobrachium sintangense caused by the existences of single male C. quadricarinatus is 784 IDR and 1,096 for the female in Lido Lake. The potential loss of M. rosenbergii due to the single P. clarkii is 1,416.76 IDR. The difference economic loss is constituted by the quantity of feed taken by the invasive species, and the economic value of competitive inferior species. This method is clearly explained in the method section and is simple to use, but more understandable for limited economics background stakeholders. However, this approach needs robust biological dynamic model. The valuation results become important reference for the policy maker to develop risk analysis in concern of introduced invasive species into an ecosystem. For holistic economic loss value valuation, further studies covering space competition and potential harmful pathogen carrier are warranted.

Abstract

Horseshoe crab is an exotic and protected marine organism in Indonesia and is considered as the living fossil animal in the world. IUCN conservation status of Carcinoscorpius rotundicauda and Tachypleus gigas is still Data Deficient, and in Indonesia research on genetic population is lacking, if any. This study aims to reveal genetic diversity of C. rotundicauda and T. gigas populations in northern Java (Demak and Madura) and Balikpapan waters. This research was conducted by using molecular analysis with genetic markers Random Amplified Polymorphic DNA (RAPD). The primers used in this study were OPB 06, OPG 10, and OPX 03. The results showed that the highest polymorphism of C. rotundicauda was found in Demak (74.6667%) and heterozygosity was 0.2669. Furthermore, T. gigas had the highest polymorphism in Madura (74.3590%) and heterozygosity was 0.25551. Based on pairwise comparison tests, populations of C. rotundicauda and T. gigas in Demak, Madura, and Balikpapan were significantly different (p<0.05). The difference is believed due to the limitation movement of horseshoe crabs from and into the three locations, as well as the presence of natural geographic barrier. Thus,it can be concluded that horseshoe crabs in northern Java and Balikpapan waters has different genetic diversity. Genetically, horseshoe crab in northern Java or Balikpapan had relatively moderate diversity and low adaptation capability.

Abstract

Horseshoe crabs are living fossils found in Indonesia. This study examined the food habit of horseshoe crabs (Carcinoscorpius rotundicauda and Tachypleus gigas) collected from Balikpapan coastal waters, East Kalimantan. Horseshoe crabs were captured using gill nets and picked by hand along the Balikpapan coast. The width of the prosoma and the body weight of each individual were measured, and the gut contents were analysed to determine the preponderance index, food niche breadth, and niche overlap. Carcinoscorpius rotundicauda prosoma widths ranged from 4.1 to 15.4 cm and those of Tachypleus gigas ranged from 2.8 to 24 cm. Eight food items were found in the gut of the horseshoe crabs, namely: bivalves, gastropods, scaphopoda, polychaetes, echinoderms, crustaceans, leaf litter and others. Based on the preponderance index, gastropods were the main food item of the two horseshoe crab species. In accordance to the food composition the horseshoe crabs inhabiting Balikpapan coastal waters are categorized as benthivores.

Abstract

Marine pollution can have a negative impact on aquaculture. For this reason, an appropriate and precise compensation calculation formula is needed. This study aims to formulate a formula for compensation calculating for aquaculture by reconstructing formula in PermenLH No. 7/2014. The reconstruction of formula was analyzed descriptively qualitatively with an expert judgement approach. The results showed that production data was a key factor in the reconstruction of compensation calculation formula. There are three reconstruction results formulas, namely compensation formula for aquaculture whose production data is available before and after pollution; compensation formula for aquaculture which only production data is available before pollution; and compensation formula for aquaculture which production data are not available

Abstract

One of the functions of the coastal ecosystem is to produce environmental services that can be used for marine tourism. Oil pollution incidents at the sea have caused a decline in the quality of marine tourism objects, thus reducing the number of visitors arriving and then it has implications for decreasing the income of the people who do business at tourist area. The community's claim for immediate compensation payments requires a faster calculation method. The purpose of this research is to develop a method of assessing the economic compensation for marine tourism businesses that are affected by incidents of oil pollution at the sea. The type of this research is descriptive research. The data consists of primary data and secondary data. The steps required in calculating compensation are (1) identifying tourism businesses, (2) building a theoretical concept of compensation, (3) determining the legal basis for calculating compensation, and (4) Designing a compensation formula. The application of the five compensation calculation formulas requires 18 variables. By taking the case of an oil spill incident in the North Sea of ​​Karawang which has an impact on Tanjung Pakis beach tourism, an estimate of the value of compensation (Rp/day) is obtained for the buoy rental service business is Rp 111,323.08, for bathroom services business is Rp 69,504.62, for food/beverage trading business on a small scale is Rp 71,510.77 and for food/beverage trading business on a large scale is Rp 188,569.23. For the next stage, the implementation of compensation needs to be verified against the impacted community and the payment mechanism so that it is right on target.

Abstract

Carbon emissions and their relation to shrimp farming activities getting more attention by researchers and environmentalists. Emissions of carbon and other greenhouse gases are concluded as drivers of climate change due to global warming. On the contrary, climate change is proven to determine the continuity and sustainability of shrimp farming activities. The dynamics of carbon and profitability are different for the three cultivation technologies (extensive, semi-intensive, and intensive), it caused by differences in the number and types of production inputs, and facilities and infrastructure, and also differences in productivity. This study aims to formulate the blue growth of aquaculture areas in the coastal area of Karawang Regency-West Java related to carbon emission within the DPSIR framework and use trade off analyses to obtain shrimp farming technologies alternative that are low in carbon emissions. Our conclusion to be able to reduce the carbon emissions, and increase the carbon sequestration and stock as effort for shrimp farming blue growth through optimize the spatial use supervision and increase the productivity of shrimp farming. The lowest carbon emission of shrimp farming technology are semi-intensive, intensive and extensive, respectively
