Species Diversity of Bivalves and Gastropods at the Tanjung Rising Coastal, Bangka Belitung Island

Abstract

Tanjung Rising Coastal, located in Dendang Village, Bangka Belitung Islands, has a large variety of substrates and organisms. One of the types of marine life studied is the Mollusk Phylum including the Bivalve and Gastropod classes. To find out the diversity of Bivalvia and Gastropoda, this study was carried out on Tanjung Rising Coastal, Bangka Belitung Islands. The study was conducted in December 2020-August 2021, using belt transect method with purposive sampling technique. Samples were collected at station 1 with a sandy substrate and station 2 with a muddy substrate. The results of this study found 1,372 individuals from the Bivalvia class consisting of 7 families and 12 species, while from the Gastropod class yielded 2,630 individuals consisting of 5 families and 7 species. The diversity and evenness index at both stations is relatively low which means that there are species that dominate, because both stations have good habitats for the dominating species. In addition, temperature, pH, salinity, depth, and strong currents showed good values for Bivalvia and Gastropoda habitat. In summary, Tanjung Rising Beach is still a good habitat for invertebrate animals, especially Bivalvia and Gastropoda.

Development Handout about Bambusa vulgaris Population Structure in the Lake Sari Embun Region, Kalimantan Selatan as Supporting the Plant Ecology Course Material

“…Population structure is important to study to determine the state or condition of a habitat (Ismail et al, 2015;Syarifah & Maulana, 2016;Raihani et al, 2023). It has the same point with animal (Pertiwi & Lathifah, 2019;Ratih et al, 2021;Triacha et al, 2021;Fatonah et al, 2023;Mufida et al, 2023;Putri et al, 2023).…”

Keanekaragaman Kelas Bivalvia Di Pantai Cibuaya Ujung Genteng

“…Zona intertidal pada umumnya dapat dibedakan menjadi tiga tipe substrat, yaitu substrat batu karang, substrat berpasir, dan substrat berlumpur (Erlania et al, 2015). Famili yang sering ditemukan pada zona intertidal yaitu famili Arcidae, famili Cardiidae, famili Tellinidae, dan famili Veneridae (Supratman et al, 2019;Fatonah et al, 2023) Berdasarkan observasi awal banyak ditemukan bivalvia di Pantai Cibuaya. Organisme ini adalah salah satu kelas dari filum moluska yang bercangkang setangkup yang pada umumnya simetri bilateral dengan memfungsikan otot aduktor dan reduktornya (Eka & Yani, 2020).…”

“…Keberadaan dari hewan Kelas Bivalvia ini memiliki peran penting di perairan pesisir baik ditinjau dari nilai ekologi maupun ekonomi (Fatonah et al, 2023). Penelitian keanekaragaman Kelas Bivalvia belum pernah dilakukan di Pantai Cibuaya Ujung Genteng.…”

“…Dalam hal ini, kondisi perairan di Pantai Cibuaya cukup stabil dan kualitas lingkungannya sangat mendukung kelangsungan hidup semua jenis Bivalvia yang ada sehingga memungkinkan interaksi spesies yang terjadi di dalam komunitas baik. Kondisi Pantai Cibuaya ini dengan tiga macam substrat menyerupai Pantai Tanjung Rising Kepulauan Bangka Belitung (Fatonah et al, 2023) serta Pantai Drini Gunung Kidul Yogyakarta (Mufida et al, 2023). Hasil pengukuran parameter abiotik di Pantai Cibuaya Ujung Genteng, meliputi suhu, pH, salinitas, kelembapan, kecepatan arus, dan intensitas cahaya (Tabel 2).…”

Development of E-Leaflet Based Learning Media to Improve Student Learning Outcomes in Excretion System Materials

“…Through the Ministry of Education and Culture, the government has banned schools from carrying out face-to-face learning and ordered the learning process to be carried out online (Syah, 2020;Hendriyani et al, 2021;Septiadi et al, 2022) . Although we know, field study will give more experience to students and precise result (Pertiwi & Lathifah, 2019;Fatonah et al, 2023;Mufida et al, 2023), however online system is the best way to deliver subjects now. Online learning is a new way of teaching and learning that utilizes electronic devices, especially the internet, in the learning process.…”
