The high level of community needs towards the fulfillment of the necessities of life increases the activity of the utilization of natural resources especially coastal and sea. Ihamahu Village has nine lagoons that have the potential to meet the needs of people because of the high productivity of lagoon ecosystems. The purpose of this research is to know and map the form and pattern of utilization conducted by Ihamahu Village society on lagoon ecosystem. The research method was conducted using questionnaire directly in Ihamahu Village through FGD (Focus Group Discussion) activity. Analysis data of FGD results will be poured in the form of maps and patterns of community utilization Ihamahu Village in the lagoon ecosystem. The results of this research show that the utilization of lagoon ecosystem is catching fish, bameti and garbage disposal. All three activities are undertaken throughout the year with less intentity especially in fishing activities and bameti occur in the west season. The high number of fishing activities using redi fishing equipment that is not environmentally friendly and has been prohibited by the government resulted in a decline in the number and size of the catch. For that form and pattern of utilization that has been done so far needs to be regulated so as to produce sustainable lagoon ecosystem management. ABSTRAK Tingginya tingkat kebutuhan masyarakat terhadap pemenuhan kebutuhan hidup meningkatkan aktivitas pemanfaatan sumberdaya alam khsusunya pesisir dan laut.

Increasing the activity of the utilization of mollusc resources by the community, both domiciled around and outside the waters of Tanjung Tiram Beach can have an impact on the sustainability of these resources. This study aims to analyze the density of mollusc and identify the activity of utilization of mollusc resources in the waters of Tanjung Tiram Beach. The study was conducted in October-November 2019 in the waters of Tanjung Tiram Beach, Poka Village. Data collection is taken using the quadratic linear transect method and interviews. The results showed the highest density was represented by Nassarius quadrasi for the gastropod class while for the bivalvia class it was represented by Marcia sp. The high density in both types of mollusc is due to habitat suitability supported by the quality of the waters. Based on respondent data, there are 20 types of mollusc that are used both for consumption, sale and as raw materials for making accessories through the "bameti" activity. Utilization activities are carried out by groups of women and children. The time of taking mollusks is done at low tide which takes place 2 times a week using aids such as coconut shells, spoons, drain and machetes. ABSTRAK Meningkatnya aktivitas pemanfaatan sumberdaya moluska oleh masyarakat, baik yang berdomisili di sekitar maupun di luar perairan Pantai Tanjung Tiram dapat berdampak terhadap keberlanjutan sumberdaya tersebut. Penelitian ini bertujuan untuk menganalisis kepadatan moluska serta mengidentifikasi aktivitas pemanfaatan sumberdaya moluska di perairan Pantai Tanjung Tiram. Penelitian dilakukan pada Oktober-November 2019 di perairan Pantai Tanjung Tiram Desa Poka. Pengumpulan data dilakukan dengan menggunakan metode transek linier kuadrat dan wawancara. Hasil penelitian menunjukkan densitas tertinggi diwakili oleh Nassarius quadrasi untuk kelas gastropoda sedangkan untuk kelas bivalvia diwakili oleh Marcia sp. Tingginya densitas pada kedua jenis moluska ini disebabkan oleh kesesuaian habitat yang didukung oleh kualitas perairan. Berdasarkan data responden, terdapat 20 jenis moluska yang dimanfaatkan baik untuk dikonsumsi, di jual maupun sebagai bahan baku pembuatan aksesoris melalui aktivitas “bameti”. Aktivitas pemanfaatan dilakukan oleh kelompok perempuan dan anak-anak. Waktu pengambilan moluska dilakukan pada saat air surut yang berlangsung 2 kali dalam seminggu dengan menggunakan alat bantu seperti tempurung kelapa, sendok, serok dan parang.

Zona intertidal merupakan lingkungan yang heterogen karena komposisi dan struktur habitatnya, sehingga mensuport keragaman flora dan fauna. Organisme yang ditemukan di zona intertidal berhadapan langsung dengan kondisi fisika-kimia selama periode pasang surut. Gastropoda dapat ditemukan di darat, perairan tawar, dan perairan laut. Saat ini, informasi tentang diversitas spesies gastropoda di zona intertidal Negeri Oma, Maluku Tengah, Indonesia masih sangat terbatas dan belum terdokumentasi. Penelitian ini bertujuan untuk mengidentifikasi spesies gastropoda, menentukan kepadatan dan diversitas spesies gastropoda yang ditemukan pada tiga zona intertidal Tuhurui, Sila dan Hitalawa di Negeri Oma, Maluku Tengah pada bulan Maret 2022. Sampling dilakukan dengan menggunakan metode transek garis. Lima transek ditempatkan pada masing-masing lokasi sepanjang 150 meter pada setiap transek. Kuadrat berukuran 1 m2 ditempatkan sepanjang garis transek dengan jarak antar kuadrat 10 meter. Ada enam ordo gastropoda (Lepetellida, Trochida, Cycloneritida, Littorinimorpha , Caenogastropoda dan Neogastropoda) yang termasuk dalam 24 famili dan 92 spesies yang ditemukan dalam penelitian ini. Jumlah spesies dan kepadatan gastropoda bervariasi berdasarkan lokasi sampling. Zona intertidal Hitalawa memiliki indeks keragaman spesies (H`) tertinggi (H` = 3.560) dibanding dengan index keragaman spesies pada zona intertidal Tuhurui dan Sila. Neritidae dan Muricidae merupakan spesies yang predominan pada semua lokasi sampling. Indeks keseragaman (J`) berkisar antara J`= 0,753 dan J`= 0,846. Indeks dominansi bervariasi antara D = 0,048 dan D = 0,073.

Gastropoda diversities can be used as an ocean health index The higher the species diversity of marine gastropod s, the better the ocean environment. Recently, there is no publication on gastropod communities in the intertidal zone of Seri District, Ambon, Indonesia. The research on gastropoda communities was conducted in July 2023 at the intertidal zone of Seri district, Ambon. The objectives of the research were to identify the species of gastropods, to analyze its ecological density and abundance, and also to analyze gastropod diversity indices. Sampling was done at three sampling sites with simple random sampling method during low tide with applying sampling kuadrat about 5x5m. A total of 21 species of marine gastropod were found in this study which grouped into six ordo, 11 family and 16 genera. The higest number of species found in the ordo of Neogastropoda. Patelloida striata has the highest ecological density in station 1 and station 2 (7 individu.m-2 and 11 individu.m-2, respectively), whereas Patteloida saccarinoides and Nerita polita have the highest ecological density in station 2 (each has 8,47 individu.m-2). Shannon diversity index (H`) varied between 1,987 and 1,984. Pielou evenness index (J`) ranged from 0,656 to 0,903. Whereas Simpson dominance index (D) varied from 0,146 to 0,223. It can be concluded that gastropod species diversity in the intertidal zone of Seri District was categorized as low diversity, evenness index was moderate to higher, while there was no dominance species in the communities.
