Abstract

Mangrove forests in Desa Bakau, Sambas Regency, West Kalimantan play an important role as a habitat for various types of aquatic biota, one of them being gastropods. Gastropods are reported to have a wide distribution in both inland and marine waters. Local people catch them for sale and consumption. An inventory of gastropod species in the mangrove area of Desa Bakau can provide initial information regarding the diversity of existing species. This data can be used as a database for sustainable management and utilization of natural resources. The purpose of this study was to identify the species of gastropods in the mangrove of Desa Bakau, Sambas Regency, West Kalimantan. This study used the exploratory method of collecting gastropods at the observation station. The results found 5 types of gastropods in Desa Bakau, such as Cassidula, Ellobium, Cerithidea, Littoraria, and Pirenella. Keywords: gastropods, mangrove, mollusk, Sambas Abstrak Hutan mangrove di Desa Bakau, Kabupaten Sambas, Kalimantan Barat berperan penting sebagai tempat berbagai jenis biota perairan, salah satunya yaitu gastropoda. Gastropoda dilaporkan memiliki distribusi luas baik di perairan darat maupun laut. Masyarakat setempat melakukan penangkapan untuk dijual dan dikonsumsi. Inventarisasi jenis gastropoda yang ada di area mangrove Desa Bakau dapat menjadi informasi awal mengenai keanekaragaman jenis yang ada. Data tersebut dapat digunakan sebagai database dalam pengelolaan berkelanjutan serta pemanfaatan sumberdaya alam yang ada. Tujuan penelitian ini adalah mengidentifikasi jenis gastropoda di area mangrove Desa Bakau, Kabupaten Sambas, Kalimantan Barat. Penelitian ini menggunakan metode eksplorasi dengan mengambil gastropoda yang ada di stasiun pengamatan. Hasil penelitian ditemukan 5 jenis gastropoda mangrove di Desa Bakau, yaitu Cassidula, Ellobium, Cerithidea, Littoraria, dan Pirenella. Kata kunci: gastropoda, mangrove, moluska, Sambas

Abstract

Mangrove vegetation has a wide range of distribution on the Indonesian coast, including Pemangkat, Sambas Regency, and West Kalimantan. Near this area, there are various activities, such as industrial, fishing, and shipping which are possible sources of heavy metal pollution. Water pollution caused by heavy metals is one of the serious problems. This condition can reduce water quality and has an impact on aquatic organisms. Monitoring of water quality needs to be done to reduce health problems and maintain the stability of aquatic ecosystems. Mudskipper (Boleophthalmus sp.) can be used as a bioindicator due to its ability to accumulate heavy metals from the environment, especially in mangrove areas. Heavy metal such as cadmium (Cd) is difficult to decompose and toxic to the environment and biota. This heavy metal pollution may originate from port and fisheries activities. The aim of this study was to determine the Cd content in the Mudskipper, waters, and sediment samples. Sampling was carried out at two stations. Analysis of the Cd content was done using Atomic Absorption Spectrophotometry (AAS). The result showed that concentrations of Cd in the waters and sediment samples were above the threshold. Meanwhile, the Cd level in Mudskipper flesh was still below the maximum limit. Keywords: heavy metal, cadmium (Cd), mudskipper, Pemangkat, West Kalimantan

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.
