Abstract

Pelabuhan Perikanan Nusantara (PPN) Teluk Awang berada di Desa Mertak, Kabupaten Lombok Tengah berpotensi sebagai pusat pertumbuhan ekonomi berbasis usaha perikanan. Perikanan sebagai salah satu sektor ekonomi yang memiliki peran penting terutama dalam menyediakan bahan pangan khususnya protein hewani. Penelitian ini bertujuan untuk mengidentifikasi jenis ikan-ikan ekonomis yang didaratkan di PPN Teluk Awang. Pengamatan sampel ikan dilakukan di PPN Teluk Awang, Kecamatan Pujut Kabupaten Lombok Tengah, pada bulan Oktober 2022. Berdasarkan hasil penelitian didapatkan 41 spesies ikan ekonomis yang tergolong ke dalam 20 famili. Ikan-ikan yang didaratkan oleh nelayan dapat dikelompokkan ke dalam ikan pelagis besar, pelagis kecil, ikan karang dan ikan demersal. Jenis ikan yang paling dominan ditemukan dari famili Scombridae (pelagis besar) dan Serranidae (ikan demersal).

Abstract

Echinoderms are one of the main components of marine biodiversity that play an important role in ecosystem function, especially as aquatic detritus. The purpose of this study was to determine the species of Echinoderms found in Lendang Luar Beach, North Lombok District. The study was conducted in July 2022 using the purposive sampling and free sample collection. Based on the research results, found 12 species from 6 families, namely Deadematidae (Diadema setosum, Echinothrix calamaris, and Echinothrix diadema), Echinometridae (Echinometra oblonga and Heliocidaris crassispina), Holothuriidae (Holothuria tubulosa), Ophiocomidae (Ophiomastix annulosa, Ophiocoma erinaceus, Ophiocoma pusilla, and Ophiocoma scolopendrina), Ophiothrichidae (Macrophiothrix longipeda), and Toxopneustidae (Tripneustus gratilla). O. Annulosa, M. longipeda, and T. gratilla species were found in all stations. M. longipeda had the highest number of individuals. T. gratilla has the most extensive microhabitat because it is found in all types of existing microhabitats.

Abstract

The Mandalika Coastal Area, located in Central Lombok Regency, is a row of beaches and bays that have a large coral reef ecosystem and intertidal zone area. The increasing growth of activities on the Mandalika coast will affect the life of the coral reef ecosystem, one of which is the concentration of heavy metals that exceeds the quality standard limits which will be very dangerous for coral reefs. This study aims to determine the concentration of the heavy metals lead and cadmium in Porites lutea coral reefs in Kuta, Tanjung Aan and Gerupuk beaches. Research data collection (field and laboratory) was carried out in May 2023. Coral reef preparation was carried out at the Advanced and Analytical Biology Laboratory, FMIPA, University of Mataram and measurements of heavy metal content were carried out at the Environmental Laboratory, the West Nusa Tenggara Province Environment and Forestry Service. Measurement and calculation of heavy metal content using Atomic Absorption Spectrophotometry (AAS). The results showed that the concentrations of the heavy metals lead and cadmium in Porites lutea coral reefs are < 0.0005 mg/L and < 0.0001 mg/L, which are still below the quality standards (PPRI No.22 of 2021 concerning Sea water Wuality Standards on Marine Biota). The Bioaccumulation Factors (BAF) value in all samples of P. lutea coral in Mandalika coastal waters is 0.00 mg/L, this shows that there is no accumulation of heavy metals in P. lutea coral.
