Growth is one of the important events in the life history of an organism beside reproduction. The objective of the present study was to evaluate the possibility of using the operculum to determine the growth pattern of tropical neritids (Nerita undata). Shell and operculum dimension were measured using a vernier caliper to the nearest 0.01mm. The results showed that there was a relationship between operculum dimensions (length and width) and shell, and it was also shown allometric growth pattern. The study also indicated the relationship between operculum dimension and the shell parameters.

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. Negeri Ihamahu memiliki sembilan laguna yang berpotensi untuk memenuhi kebutuhan hidup masyarakat karena produktivitas ekosistem laguna yang tinggi. Tujuan penelitian ini adalah mengetahui dan memetakan bentuk dan pola pemanfaatan yang dilakukan oleh masyarakat Negeri Ihamahu pada ekosistem laguna. Metode penelitian yang dilakukan menggunakan kuesioner secara langsung di Negeri Ihamahu melalui kegiatan FGD (Focus Group Discussion). Analisa data hasil FGD akan dituangkan dalam bentuk peta bentuk dan pola pemanfaatan masyarakat Negeri Ihamahu di ekosistem laguna. Hasil penelitian menunjukkan bentuk pemanfaatan pada ekosistem laguna yaitu penangkapan ikan, bameti dan pembuangan sampah. Ketiga aktivitas tersebut dilakukan sepanjang tahun dengan intesitas yang kurang khususnya pada aktivitas penangkapan ikan dan bameti terjadi pada musim barat. Tingginya aktivitas penangkapan ikan dengan menggunakan alat tangkap redi yang tidak ramah lingkungan dan telah dilarang oleh pemerintah mengakibatkan telah terjadi penurunan jumlah dan ukuran hasil tangkapan. Untuk itu bentuk dan pola pemanfaatan yang telah dilakukan selama ini perlu diatur sehingga menghasilkan pengelolaan ekosistem laguna yang berkelanjutan.

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. Indeks keragaman spesies gastropoda dan keserasian spesies termasuk dalam kategori tinggi dan tidak ada spesies gastropoda yang mendominasi dalam komunitas. Penelitian ini memberikan kontribusi terhadap keragaman spesies moluska di perairan Maluku. Kata Kunci: Diversitas spesies, gastropoda, kelimpahan, keserasian, zona intertidal
