Abstract

ABSTRACT The limited scientific information and lack of attention from stakeholders on the status of mangroves in Kembung River functioned as a basis of this study. Four series of Landsat data recorded in 1996, 2002, 2010, and 2013 were used to map mangrove land cover and changes detection. Hybrid classification technique, a combination of the object-based and random forest classifications, were applied in this study. The result showed that based on hybrid classification, mangrove coverage was detected within 82.6-88.4% overall accuracy. Change detection analyses showed that the mangrove area of Kembung River was relatively stable. For nearly two decades, we found mangrove loss about 197.2 ha, gain of 251.1 ha, and unchanged of 2904.9 ha. Changes in mangrove were generally caused by anthropogenic factors such as mangrove replanting, logging, changes over the function of mangroves into the road, embankment, settlement, shrimp farms, and natural growth. Serious attention from various parties are needed to maintain the existence and sustainablility of mangrove ecosystems in Kembung River.   Keywords: Mangrove, Sungai Kembung, monitoring, Landsat, hybrid classification

Abstract

Mantis shrimp is an export commodity that caught by fishermen in Kuala Tungkal. Mostly, the fishermen use gillnet as their main fishing gear. However, this fishing effort shares open access and common property to be its aquatic resources with other fishing businesses that may bring potential conflicts related to fishing areas, utilization of aquatic resources, fishing gear, etc. Thus, this current study aims to analyze economic value and potential conflicts in mantis shrimp catch in Kuala Tungkal. A survey method was applied as the research method. From 2015 to 2017, the export volume and value of shrimp commodities continued to increase. The results show that profit value (π) possessed by catching mantis shrimp is Rp637.500,00 per trip, R/C 5.6 and PP 39 trips showing a good financial value and potential to be developed. Meanwhile, potential conflicts in catching mantis shrimp tend to be low since there is no overlapping fishing area for each fishing gear operated by different aquatic resource users. It means that the operation of fishing gear has been set well by the community of fishing businesses in that area so that the potential for social conflicts between aquatic resources users is also low.
