Diversity of mollusks (bivalves and gastropods) in degraded mangrove ecosystems of Kolaka District, Southeast Sulawesi, Indonesia. Biodiversitas 21: 5884-5892. Mollusks are one of the mangrove organisms whose classes are bivalves and gastropods. It plays an important role in mangrove and marine ecosystems as filter feeders, predators, and herbivores. This study aims to knows the diversity and abundance of mollusks (bivalves and gastropods) in several mangrove ecosystems in the Kolaka coastline as well as the similarity of these locations. This study was conducted in mangrove ecosystems of Induha Village, Mangolo Village, Tahoa Village, and Towua Village of Kolaka District, Southeast Sulawesi, Indonesia, from July to August 2019. This is a transect method stretched along a 100 m line perpendicularly from the seaward. The size of the mollusks subplot was 1 m2 and placed along the line transect. Each line transect comprises 10 subplots. To analyze the diversity index, evenness index, and its abundance, Kaleida Graph 4.0 version was used. This research indicates that the mollusks consist of 4 families of bivalves with 6 species and 10 families of gastropods with 182 species. It also found out 23 species of mollusks scattered to each location. The molluscan species which spread in all four mangrove ecosystems were Terebralia sulcata, Nerita planospira, and Batillaria multiformis. In Induha, the mollusks species were Anadara notabilis and Drupella margariticola. Meanwhile, Saccostrea cucullata, Pirenella incisa, Clithon oualaniensis, and Clithon pulchellum were only found in Towua. The diversity index of bivalves in each location was categorized as low diversity index category, as well as gastropods were categorized as medium diversity index. The highest diversity index of gastropods was in Induha (H' = 1.96). It was supported by the good mangrove ecosystem for mollusks' habitat. The lowest diversity index of gastropods was in Towua (1.41). This research depicts that three kinds of species with high abundance rate whose rates were >1 ind/m2are located in two different locations namely; P. incisa (3.9 ind/m2) and S. cucullata (3.2 ind/m2) in Towua and followed by B. multiformis (2 ind/m2) and Isognomon ephippium (1.2 ind/m2) in Mangolo.

Abstract. Anzani L, Madduppa HH, Nurjaya IW, Dias PJ. 2019. Short Communication: Molecular identification of White Sea Squirt Didemnum sp. (Tunicata, Ascidiacea) colonies growing over corals in Raja Ampat Islands, Indonesia. Biodiversitas 20: 636-642. Indonesia is at the center of the Coral Triangle, the region with the world’s highest marine biodiversity. The Raja Ampat archipelago in east Indonesia has one of the oldest networks of marine protected areas in the country and is a top priority area for marine conservation. The area is however under anthropogenic pressure from growing tourism, developments and exploration of natural resources. The most likely associated introduction of non-native species is however largely unexplored. Colonial ascidians or ‘sea squirts’ comprise a high number of species, many of them reported as introduced or invasive worldwide. In this study, we investigate the presence of white colonial ascidian colonies noticed to overgrow sections of the coral reefs in central Raja Ampat. We use DNA barcoding to address the colonies’ species identification and explore haplotype diversity to determine the species native or introduced status. We produced 22 DNA barcodes belonging to four potential cryptic Didemnum sp. species present in the Raja Ampat archipelago, Indonesia. Overall, the high number of haplotypes found in the area suggest these to most likely to be native species. The present work represents, as far as the authors are aware, the first time that such species were investigated in Raja Ampat. We hope with this work to create awareness for the topic of introduced and invasive species in the area and motivate further studies in Indonesia.

E-COMMERCE WEBSITE AS A MEDIA FOR PROMOTING SALES OF FISHERMEN’S WIFE GROUP SEAFOOD PROCESSING IN KARANGANTU. Currently fish caught from husbands who work as fishermen can only be marketed fresh, and if they are not sold, they will be discarded or used as animal feed. Fish product development processing is being carried out by agencies for groups of fishermen’s wives. We carried out community service by marketing team that can help increase fishermen household income. Marketing strategy is by creating a website. The objectives of community service through this activity are as follows: (a) Introducing fishermen’s wives to information media for sales, (b) Creating Banten Bahari E-Commerce Website (BAHARI) which later can be used as marketing media by fisherman wives. Method to achieve the first goal is by community education, and for online we use the Waterfall method. The socialization of online media introduction for marketing marine products in Karangantu was well responded by fishermen’s wives. Making the BAHARI website is one of promotional media that fishermen’s wives can use in the future.

ABSTRAK Sumber daya manusia yang unggul dapat diperoleh dari pemenuhan gizi seimbang di lingkup keluarga. Memastikan terpenuhinya gizi di seluruh lapisan masyarakat adalah tugas seluruh masyarakat Indonesia, terutama pada lingkungan dengan tingkat kesejahteraan yang rendah seperti nelayan. Masyarakat sekitar PPP Lempasing, Kelurahan Keteguhan, Kota Bandar Lampung yang sebagian besar berprofesi sebagai nelayan belum mengetahui hal-hal terkait pentingnya memperhatikan keseimbangan gizi pada keluarga. Pengabdian kepada masyarakat ini bertujuan untuk memberikan pemahaman dalam pencegahan stunting di lingkup keluarga dengan pemenuhan gizi. Metode yang dilakukan adalah sosialisasi oleh tim Pengabdian kepada Masyarakat (PkM) Universitas Pendidikan Indonesia yang bekerjasama dengan Politeknik Negeri Lampung dan Rumah Zakat Provinsi Lampung. Dari hasil kuesioner kegiatan sosialisasi ini dapat dilihat bahwa masyarakat mengalami peningkatan 25,63% mengenai pemahaman pentingnya memenuhi gizi seimbang keluarga. Kata Kunci: Gizi, Sosialisasi, Stunting, Lampung  ABSTRACT Superior human resources can be obtained from the fulfillment of balanced nutrition in the family scope. Ensuring the fulfillment of nutrition at all levels of society is the task of all Indonesian people, especially in environments with low welfare levels such as fishermen. The community around PPP Lempasing, Keteguhan Village, Bandar Lampung City, most of whom work as fishermen, do not know things related to the importance of paying attention to nutritional balance in the family. This community service aims to provide an understanding in preventing stunting in the family scope by fulfilling nutrition. The method used is socialization by the Community Service (PkM) team at the Indonesian Education University in collaboration with the Lampung State Polytechnic and the Lampung Province Zakat House. From the results of this questionnaire, it can be seen that the community experienced an increase of 25.63% regarding the understanding of the importance of fulfilling family balanced nutrition.

The need for data on marine resources is increasing, Indonesia as one of the world's maritime countries plays a big role in this. The successful application of big data on marine resources is not only seen from the technology used in it but it is also must related to other system components. A qualitative approach is used in this study to produce a big data model that can be applied to marine resources. This research produces a big data model from the perspective of a Knowledge Management System (KMS) which consists of four elements or layers, namely organization, Big Data Process and Technology Information, and people as users. The integration of these four elements is expected to promote economic transformation and knowledge in the marine and fishery sectors.
