Abstract

Macroalgae are thallus plants that do not have organs in the form of roots, stems, and leaves that are not true. The existence of macroalgae as producer organisms contributes to the life of aquatic biota, especially herbivorous organisms in the waters of Temajo Island, Mempawah Regency, West Kalimantan. This study aims to determine the abundance, relative abundance, relative frequency, diversity index, uniformity index, and dominance index in the waters of Temajo Island. This research was conducted in August 2022, the sampling locations were three stations and were determined using the exploratory method based on the presence of macroalgae found. Macroalgae sampling was carried out using a quadratic transect of 10x10 m and based on the research results obtained 5 families, 3 classes, 4 orders, and 6 genera consisting of Sargassum, Turbinaria, Padina, Halimeda, Codium, and Amphiroa. The results of the analysis found that the genus Sargassum had abundance, relative abundance, and relative frequency (K = 0.72-2.35 ind/m2, KR = 49.99%, F = 0.83) of macroalgae communities in the waters of Temajo Island, Mempawah Regency, Kalimantan West, has a low-medium diversity value, low-high uniformity index and low-high dominance index. Keywords: Community Structure, Macroalga, Temajo Island, Mempawah Abstrak Makroalga merupakan tumbuhan thallus yang tidak memiliki organ-organ berupa akar, batang dan daun tidak sejati. Keberadaan makroalga sebagai organisme produsen memberikan sumbangan bagi kehidupan biota akuatik, terutama organisme-organisme herbivor di perairan Pulau Temajo Kabupaten Mempawah Kalimantan Barat. Tujuan dari penelitian ini yaitu mengetahui kelimpahan, kelimpahan relatif, frekuensi relative, indeks keanekaragaman, indeks keseragaman, dan indeks dominansi di perairan Pulau Temajo. Penelitian ini dilakukan pada bulan Agustus 2022, lokasi pengambilan sampel sebanyak tiga stasiun dan ditentukan menggunakan metode Eksploratif berdasarkan keberadaan makroalga yang ditemukan. Sampling makroalga dilakukan menggunakan transek kuadrat dengan ukuran 10x10 m. Berdasarkan hasil penelitian diperoleh 5 famili, 3 kelas, 4 ordo, dan 6 genera yang terdiri dari Sargassum, Turbinaria, Padina, Halimeda, Codium dan Amphiroa. Hasil Analisa mendapatkan Genus Sargassum memiliki kelimpahan, kelimpahan relatif, dan frekuensi relatif (K = 0,72-2,35 ind/m2, KR = 49,99%, F = 0,83) komunitas makroalga di perairan Pulau Temajo Kabupaten Mempawah Kalimantan Barat, memiliki nilai keanekaragaman rendah-sedang, indeks keseragaman rendah-tinggi dan indeks dominansi rendah-tinggi.

Abstract

Lemukutan Island has the potential of natural resources with a high level of diversity, including phytoplankton. Lemukutan Island has been developed as a marine tourism destination and other activities. A way to monitor water conditions is by observing physical, chemical, and biological parameters. This study aimed to determine the community structure of phytoplankton as a water quality bioindicator and analyze the environmental parameters' correlation to the abundance of phytoplankton in Teluk Melanau, Lemukutan Island. Determination of sampling stations using a purposive sampling method. Phytoplankton identification, quantity, biological index, and measurement of environmental parameters were carried out in this study. The results showed that the phytoplankton community consisted of 77 genera and Bacillariophyceae has the highest percentage contribution (90.44%). The most common genera were Cocconeis, Nitzchia, Synedra, and Chaetoceros. The abundance of phytoplankton ranged from 2-1521 ind/L. The biological index showed that Teluk Melanau was in an unpolluted condition. Environmental parameters were still in the optimal range for the growth of phytoplankton. The abundance of phytoplankton is very strongly correlated with salinity, DO, nitrate, and phosphate, strongly correlated with pH and very weakly correlated with brightness, temperature, and current velocity. Keywords: Community structure, phytoplankton, bioindicator, Lemukutan Island. Abstrak Perairan pulau Lemukutan memiliki potensi sumberdaya alam, termasuk fitoplankton. Pada saat ini, pulau Lemukutan telah dikembangkan sebagai destinasi wisata bahari dan berbagai aktivitas lainnya. Aktivitas tersebut dapat memberikan dampak terhadap kualitas perairan. Salah satu cara melakukan monitoring kondisi perairan yaitu dengan cara pengamatan parameter fisika, kimia, dan biologi. Penelitian ini bertujuan untuk mengetahui struktur komunitas fitoplankton sebagai bioindikator kualitas perairan dan menganalisis korelasi parameter lingkungan terhadap kelimpahan fitoplankton di Perairan Teluk Melanau, Pulau Lemukutan. Penentuan stasiun pengamatan dilakukan dengan menggunakan metode purposive sampling untuk mewakili rona lingkungan yang ada. Identifikasi fitoplankton, kelimpahan, indeks biologis, dan pengukuran parameter lingkungan dilakukan dalam penelitian ini. Hasil penelitian menunjukkan struktur komunitas fitoplankton terdiri dari 77 genera, dimana Bacillariophyceae merupakan komponen dengan persen kontribusi tertinggi (90,44%). Jenis yang paling banyak ditemukan yaitu Cocconeis, Nitzchia, Synedra, dan Chaetoceros. Kelimpahan fitoplankton berkisar antara 2-1521 ind/L. Indeks biologi menunjukkan bahwa perairan Teluk Melanau berada pada kondisi tidak tercemar. Parameter lingkungan masih dalam rentang optimal untuk pertumbuhan fitoplankton. Kelimpahan fitoplankton berkorelasi sangat kuat dengan salinitas, DO, nitrat, dan fosfat, berkorelasi kuat dengan pH dan berkorelasi sangat lemah dengan kecerahan, suhu, dan kecepatan arus. Kata kunci: struktur komunitas, fitoplankton, bioindikator, pulau Lemukutan.

Abstract

Desa Jawai Laut is a coastal village in Sambas Regency, West Kalimantan with the potential of marine waters that can support the community's economy. One of the activities carried out is the seaweed cultivation of Eucheuma cottonii using the longline method. The development of cultivation activities can be supported by optimal water conditions to support seaweed production. The aim of this study was to analyze the water quality in Desa Jawai Laut, Sambas Regency for the development of seaweed cultivation. Determination of location sites was carried out systematically, as many as 7 stations with a distance of 500 m. The water quality index was analyzed using the CCME-WQI method. The results showed that in general, the water quality of Desa Jawai Laut was in a good category with a CWQI value of 80. Stations I and IV were in the excellent category and were recommended as locations for the development of seaweed cultivation.
