Abstract

Cilacap and Kebumen are potential coastal habitat for mole crab such as Hippa adactyla. Ecosystems condition of both locations is distinct. Each organism have to develop adaptation strategy to deal with environmental variation. H. adactyla usually burry into substrate to cope with environmental stress. They have been adapted to local habitat in order to be able for survive and reproduce. However, it has not been well known whether the adaptation strategy may vary the performance of morphology. This study focused on morphological variation of mole crab H. Adactyla. The sample was carried out on August 2014. Mole crabs were caught using traditional fishing gear called “sorok”. They were 118 individuals which where caught in Cilacap, while 102 individuals that were found in Kebumen. The result showed that H. adactyla walk vertically (backwards). These caused by carapace length and carapace width ratio. T-student analysis showed that relative growth for males were negatively allometric and isometric for female in both habitat. Mean of condition factor (K) for males in Cilacap was 0.0319 ± 0.0025 and 0.0315 ± 0.0028 in Kebumen. Those were significantly higher for females (p<0.05) in Cilacap (0.0325 ± 0.0050) and Kebumen (0.0329 ± 0.0027). Mean of relative condition factor (Kn) was higher in Cilacap for males and females. Those variations of K and Kn related to exogenous and endogenous factors.

Abstract. The richness of biological diversity is an asset for the development and prosperity of the nation, but human needs and environmental pressure increased, especially marine biological resources, it has resulted in a decline in the population of several marine life. This causes several marine life to be rare and endangered. Conservation efforts need to be carried out covering aspects of preservation, protection, and utilization. Another preventive way that can be done is providing education to the community, especially in the elementary school young generation. Given that education related to the preservation of marine biodiversity is important to learn as early as possible, elementary school young generation are the main target for socialization about protected marine life to create a sense of care, willingness, and knowledge so that marine wealth can be preserved. Introduction of protected marine life in the Riau Islands region with participants of grade VI students at the State/Public Elementary School (SDN) 06 Gunung Kijang, Bintan Regency. The activity is carried out in several stages, namely pre-test knowledge of protected marine life, education of protected marine life in the Riau Islands region (video and pocketbook containing short stories and information on protected marine life in Riau Islands), and post-test to know enhancement of student knowledge of protected marine life. The level of understanding increased from a range of poor-moderate understanding by pre-test correct answers (47% -79%) to a moderate-high range of understanding by post-test correct answers (74% -100%).             Abstrak. Kekayaan keanekaragaman hayati menjadi aset bagi pembangunan dan kemakmuran bangsa, namun dengan meningkatnya kebutuhan manusia dan tekanan terhadap lingkungan khususnya sumberdaya hayati laut, mengakibatkan terjadinya penurunan populasi beberapa biota perairan. Hal ini menyebabkan beberapa biota perairan menjadi langka dan terancam punah. Upaya konservasi perlu dilakukan yang meliputi aspek pelestarian, perlindungan, dan pemanfaatan. Cara preventif lain yang dapat dilakukan adalah pemberian edukasi kepada masyarakat khususnya anak-anak sekolah. Mengingat pendidikan terkait kelestarian keanekaragaman hayati laut penting untuk dipelajari sedini mungkin, maka anak-anak sekolah dasar menjadi sasaran yang tepat untuk dilakukan sosialisasi mengenai biota-biota laut yang dilindungi agar terwujudnya rasa peduli, kemauan, serta ilmu pengetahuan sehingga kekayaan laut dapat terjaga. Pengenalan biota laut dilindungi di wilayah Kepulauan Riau dengan peserta siswa-siswi kelas VI di Sekolah Dasar Negeri (SDN) 006 Gunung Kijang, Kabupaten Bintan.
