Gastropod is one of the mollusk phylum that can adapt and decompose in mangrove forests. The mangrove forest in Sungai Kakap is an area that is slowly being opened due to the local community people’s activities. They opened land to build buildings, farms, and villages. This research is aimed at studying the diversity of Gastropod and the influence of the mangrove tree density on the gastropod diversity in the mangrove forest of Sungai Kakap, Sungai Kakap Village of Kubu Raya Regency. The data were taken in May 2018. The analysis was conducted using the observation method by making six observation lines. The lines were differentiated based on the density of the vegetations: dense, medium, and sparse. The number of Gastropods found in the Kakap River mangrove forest is 4 types of gastropods with a total of 252 individuals. Respectively from dense, medium, and sparse vegetation, the gastropod dominance index is 0.68, 0.37, and 0.51; the diversity index is 0.25, 0.49, and 0.33; the species average index is 0.27, 0.97, and 0.4; and the gastropod species richness index is 4.03, 1.18, and 0.7.

Diversity and habitat characteristics of macrozoobenthos in the mangrove forest of Lubuk Kertang Village, North Sumatra, Indonesia. Biodiversitas 19: 311-317. Mangrove plays an important role in coastal ecosystems including ecological, social, and economic aspects. This study aimed to determine the diversity of macrozoobenthos and water quality based on diversity index (H’), similarity Index (E), and dominance index (D) in the mangrove of Lubuk Kertang Village North Sumatra, Indonesia. The samples of macrozoobenthos (biological parameter) and water quality (physical and chemical parameters) were collected from fifteen plots in three different stations. Macrozoobenthos were collected in 1 m × 1 m transect in the mangrove forest. The biota was taken by using a shovel, inserted into a plastic bag, and identified. Results showed that eight species of macrozoobenthos were found and classified into three classes of Gastropod, Bivalvia, and Malacostraca. The highest diversity index (H′) of macrozoobenthos was found at Station II (2.39), the highest evenness index (E) was located at Station I (0.54), and the highest dominance index (D) was found at Station II (0.34). Principal component analysis (PCA) was used to determine the habitat characteristics of macrozoobenthos. PCA confirmed that station III was a habitat with suitable characteristics for the life of macrozoobenthos indicating the negative axis. The present study suggested four parameters namely salinity, clay temperature, and dissolved oxygen that should be preserved to support the survival of macrozoobenthos in the mangrove forests.

The study was conducted in April 2017, located along the Wailawa watercourses, Tawiri Village, Ambon. The method applied in these studies were Point Count, while data analysis using Shannon-Wiener Diversity Index, Evenness Index, Domination Index, Similarity Index, and Guild Composition. The results showed that the number of bird species found along Wailawa watercourse were 28 species of 25 genera, 17 families, and 8 orders. The diversity of bird species is moderate (H ‘= 2,54). The bird species similarity analysis resulted in three bird communities, including: (1) bird communities in mangrove forest, estuaries with grass vegetation, (2) bird communities in garden and settlement habitats, and (3) bird communities in mixed forest habitat. Mangrove forest and estuaries have the highest species similarities (0,63). Estuaries and mix gardens have the lowest bird similarities (0,05). Bird communities in mangrove forests and estuaries are heterogeneous because they have more species with a more equitable distribution of species abundance, while in other habitat, their are homogenous because of relatively have a low species diversity with uneven distribution of species abundance.Penelitian ini bertujuan menganalisis komunitas burung, meliputi kekayaan jenis, keanekaragaman jenis, kelimpahan relatif, kemerataan jenis, foraging guild, serta kesamaan jenis. Penelitian dilakukan pada bulan April 2017, berlokasi di sepanjang Anak Sungai Wailawa, Desa Tawiri, Kota Ambon. Metode pengambilan data adalah metode point count, sedangkan analisis data menggunakan Indeks Keanekaragaman Shannon-Wiener, Indeks Kemerataan Jenis Evennes, Indeks Dominasi Jenis, Indeks Kesamaan Jenis, dan Foraging guild. Hasil penelitian menunjukkan jumlah jenis burung yang ditemukan sebanyak 28 jenis dari 25 genus, 17 famili, dan 8 ordo. Keanekaragaman jenis burung tergolong sedang (H’ = 2,54). Hasil analisis tingkat kesamaan komunitas menghasilkan tiga komunitas burung, meliputi : (1) komunitas burung di hutan mangrove-muara sungai bervegetasi rumput, (2) komunitas burung di kebun dan permukiman, serta (3) komunitas burung di kebun campur. Hutan mangrove dan muara sungai memiliki kesamaan jenis burung tertinggi, yakni 0,63. Muara sungai dan kebun campur memiliki kesamaan jenis burung terendah, yakni 0,05. Komunitas burung di hutan mangrove dan muara sungai adalah komunitas heterogen karena memiliki lebih banyak spesies dengan distribusi kelimpahan spesies yang lebih merata, sedangkan komunitas burung pada tipe habitat lainnya adalah komunitas homogen karena keragaman jenis relatif rendah dan distribusi kelimpahan spesies tidak merata.

Policy Scenario

Mangroves provide benefits and various services to local communities living along coastal areas, particularly fishery communities. Fishery community perceptions are significant in determining attitudes towards improving mangrove conditions, which can also be addressed through restoration activities. This research was conducted to analyze fisheries communities perceptions, willingness to pay (WTP) for mangroves restoration, and mangrove forest management strategies. Field surveys were conducted from July-August 2019 and February-March 2020. Primary data were collected from respondents in four regions (Kalianda Regency, South Lampung Regency, Bandar Lampung City, and Pesawaran Regency) in Lampung Province, Indonesia, which consist of fishers, shrimp farmers, crab and wood seekers, and finfish farmers. The respondents were 193 people, and four experts were involved in the policy scenario analysis. Results revealed a gap in the value of WTP among fishery community groups, in which the average value for fishers is lower than shrimp farmers. The years of formal education significantly influenced the WTP for mangrove restoration. Based on the scenario analysis, scenario 01 become a priority strategy, where four policies (P1 = Mangrove ecotourism development in Lampung Bay; P2 = Mangrove knowledge education and training on processing mangrove based products; P3 = Restoration and conservation of mangrove forests; and P4 = Community-based management for mangrove forests utilization) show high likelihoods to be simultaneously implemented for mangroves management, with mangrove ecotourism policy as the most decisive policy. For future research, other explanatory variables can be added, such as information on family member characteristics, and to develop a bottom-up policy scenario by identifying and involving the role of the local community.

During the 1996 to 1997, large areas of mangrove forest in the Segara Anakan were cleared and converted into intensive shrimp-ponds. After one to two years, these shrimp-ponds failed and were abandoned. These abandoned ponds created large gap areas and canopy gaps, which were colonized by mangrove shrub and liana. The Segara Anakan mangrove also experienced heavy siltation, and there were tree cuttings from the remnant of the mangrove trees. This research aimed to study the colonization of mangrove vegetation at the abandoned-shrimp pond. Vegetation data were collected using rectangular plots of 25 m x 25 m with 4 replicates. The water qualities were also studied. The results revealed that the mangrove forests were composed of two layers: canopy tree and floor-vegetation. The gap areas triggered the pioneer species of mangrove shrubs and liana, Acanthus ilicifolius and Derris heterophylla, to colonize and dominate 100% of the mangrove forest floor. The mangrove trees consisted of natural and planted tree species. The natural trees were Sonneratia alba, Avicennia alba, and saplings of Aegiceras corniculatum, which  varied between 56 – 136, 4, and 4 individuals per ha, respectively. The planted trees were Rhizophora apiculata, which amounted to 4 – 12 individuals per ha, at the island of the ponds. These trees and saplings were entangled by the liana mangrove, which disturbed their growth. The A. ilicifolius and D. heterophylla prevented the mangrove tree propagules to grow, and they colonized and characterized those abandoned shrimp-ponds, which threatened the Segara Anakan mangrove ecosystem.

ABSTRACTThis research aimed to investigate the Willingness to Pay (WTP) for mangroveconservation of local communities at Salut Mengkabong Lagoon, Tuaran based on theamount of fees imposed on them. The content is based on questionnaire survey providedto local communities from Mangrove Forest Produce (MFP) to their perception inconservation programme. The survey was conducted with a priod of 7 month startedfrom September 2016 until March 2017. Contingent Valuation Method (CVM) was usedto calculate the Willingness to Pay (WTP) whereby 100 respondents were asked tocomplete the questionnaire. From the analysis, it showed that the WTP of localcommunities were affected by their monthly income. Regression model analysis withWTP = -0.087* (monthly income) + 1.789 has been formed. Whereas, the value ofmangrove forest produce (MFP) in Salut Mengkabong Lagoon has been calculated with atotal of RM728 for the direct product while for the non-direct products such as crab,bivalves, seashells and fishes cost about RM721 to RM2472 in a year. The studydocumented mangrove forest contribution to local communities in Salut MengkabongLagoon such as timber; Rhizophora mucronata and Avicennia spp, Seafood; Scyllaserrata, Geloina coaxans, various type of fishes and seashell. From the result, it washope that this study can promote a win-win situation to both local community andstakeholders to come out with an effective supervision to ensure the long-lastingdependency of local communities to the mangrove forests without undermining theirsocio-economic wellbeing.Keywords: Salut Mengkabong Lagoon, Mangroves Forest Produce, local community

 Walaupun wilayah laut dan pesisir sangat penting untuk kehidupan rakyat dan bangsa Indonesia, secara nyata perairan Kendari belum digarap secara optimal, terutama kondisi dan potensi perikanan, khususnya kepadatan dan keanekaragaman krustasea. Penelitian ini bertujuan untuk mengungkapkan dan mengidentifikasi potensi sumber daya laut di pulau-pulau kecil disekitar perairan Kendari. Penelitian dilakukan dengan cara koleksi bebas menyusuri mangrove. Data yang diambil dari penelitian ini adalah data krustacea non ekomomis dan ekonomis serta data pendukung  lingkungan (suhu, pH dan salinitas). Hasil penelitian menunjukkan parameter lingkungan di beberapa lokasi masih relatif baik untuk kehidupan krustasea di daerah mangrove. Diperoleh 377 individu, 15  jenis, 12 famili dan 1 ordo individu krustasea. Kepadatan krustasea di setiap lokasi berbeda-beda. Indeks keanekaragaman (1,121-3,744) dan indeks keseragaman (0.360-0.610) termasuk sedang, yang menggambarkan bahwa penyebaran individu relatif sama serta indeks dominansi pada penelitian ini termasuk tinggi (0,190-0,620). Dengan diperolehnya data keanekaragaman krustasea di perairan Kendari sudah sepatutnya harus lebih dicermati lagi kondisi lingkungan dan keberadaan krustasea secara periodik karena krustasea merupakan salah satu rantai makanan yang juga penting di dalam ekosistem pesisir. Kata kunci: Krustasea, keanekaragaman, mangrove, perairan KendariAlthough the marine and coastal areas are very important for the life of the people and nation of Indonesia, Kendari waters significantly have not worked optimally, especially the condition and potential of fisheries, particularly the density and diversity of crustaceans. This study aims to reveal and identify the potential of marine resources in small islands around the waters of Kendari. Research carried out by way of free collection along the mangrove. Data from this study are from non economical, economical crustaceans and environmental data (temperature, pH and salinity) as well as to supporting the environmental. The results shows several areas of environmental parameters is still relatively good for the life of crustaceans in mangrove areas. Provided 377 individuals, 15 species, 12 families and 1 order of individual krustaseans. Krustasean densities at each location is different. Diversity index (1.121-3.744) and Similarity index (0,360-0,610) catagories in medium grade, which illustrates that the spread of crustacea is relatively the same. Index of dominance in this study was high (0.190-0.620). By obtaining data of  diversity crustaceans in the waters of Kendari, should be more rutiny and  should have been more better protecting the environmental conditions and also the presence of crustaceans periodically because crustaceans are one of the food chain are also important in the coastal ecosystem.Key words: Crustaceans, diversity, mangrove forests, waters Kendari

Study on the potency of mangroves forest in Serangan Island as ecotourism area in South Denpasar District, Denpasar, Bali. Mangrove Forest on Serangan Island is an area managed by PT.Bali Turtle Island Development (BTID) which is a government land under the supervision of the Bali Provincial Forestry Agency (Dinas Kehutanan Provinsi Bali) and Nature Resource Conservation Center (BKSDA). The total area of mangrove forest about of 33 hectares, the mangrove forest in Serangan Island indicate to have biophysic potency such diversity of mangrove species and diversity of fauna. The purpose of this study is to identify the biodiversity of mangrove forests and to assess the suitability of mangrove forests as ecotourism areas. The method used in this research was the conformity analysis proposed by Bahar (2004) and Yulianda (2007) to assess the potency of mangrove forest with biophysical approach. The results of this study found that the area of mangrove forest on Serangan Island was dominated by mangrove species Sonneratia and Rhizopora, with diversity of fauna found such as birds, reptiles, and marine biota at each point of observation area. The tourist suitability index (Ik) of mangrove forest was 153 and belong to medium category or potentially as an ecotourism area. Recommendation for ecotourism development area of mangrove forest consist of basic concept of development which were buffer area and eco-tourism area. Then ecotourism activities were develop e.g natural interpretation, nature viewing, bird watching, photo hunting, board walks, and fishing. In addition, support from local community and tourists around the mangrove forest was very much to developed Serangan Island as an ecotourism area.
