Abstract

Tarakan City is a city that has potential natural resources to be developed. One of the areas in the town of Tarakan is Tanjung Pasir, where the residents live in the coastal area. This study aims to determine the quality of the waters of the dune by using the plankton community structure as a water bioindicator. As a research object, Plankton communities in Tanjung Pasir waters include abundance, diversity index, uniformity index, and dominance index. This study uses a quantitative descriptive method with the research location being carried out at two points, namely Station I in the mangrove area and Station II close to residential areas. Sampling was conducted every two days, 15 times out in the field. The types of phytoplankton found in five classes, namely Bacillariophyceae, Coscinodiscophyceae, Cyanophyceae, Mediophyceae, and Dinophycea lessons and zooplankton from Crustacea class at Station I and Station II. Station I and Station II were from classes. The most abundant types of phytoplankton are found in Bacillariophyceae and Dinophyceae because these two classes dominate all kinds of phytoplankton worldwide. The abundance value of phytoplankton at; Station I was 354 cells/l; at Station II, it was 202 cells/l. The abundance of zooplankton at; Station I was 40 ind/l, and at Station, II was 38 ind/l. The diversity index at the two stations is in the medium category, with the uniformity index being in the high uniformity category and the dominance index at each low. Based on the value of the plankton community structure, Tanjung Pasir waters are classified as lightly polluted. Environmental factors of Tanjung Pasir waters in Tarakan city include the physical and chemical characteristics of Station I and Station II, which are still suitable for the life of aquatic organisms.

Abstract

Perairan Bulungan yang berada di kabupaten Bulungan terindikasi memiliki ragam sumberdaya perikanan tangkap yang potensial. Ragam sumberdaya ikan tersebut salah satunya adalah ikan kakap putih (Laters calcalifer). Pola pemanfaatan sumberdaya ikan secara terus menerus karena potensi ekonomis sumberdaya tersebut, tanpa adanya pola penangkapan yang lestari akan berdampak pada penurunan potensi sumberdaya ikan tersebut. Tujuan riset ini menjelaskan aspek makanan dan kebiasaan makan yang meliputi analisa Persentase Ikan dengan Lambung Berisi (PILB), Index Stomach Content (ISC) dan Index Relative Important (IRI). Riset ini telah dilakukan dalam 4 bulan (Desember 2021-Maret 2022), dengan lokasi asal sampel dari perairan Muara Ancam, Muara Bulungan dan Muara Mapat Kabupaten Bulungan. Metode riset menggunakan pendekatan deksriptif kuantitatif dalam kegiatan observasi dan purposive sampling dalam pengumpulan sampel. Hasil penelitian menunjukkan dari total 69 sampel, nilai PILB yang didapatkan 100% dengan rata-rata nilai ISC sebesar 0,59% dari bobot tubuhnya. Ikan kakap putih (L. calcarifer) merupakan ikan karnivora dengan jenis makanan utamanya berdasarkan analisa IRI yaitu dari kelompok chordata (ikan) sebesar 49,09%, makanan pelengkap yaitu makanan lumat (tidak teridentifikasi) sebesar 25,38% dan udang 24,41%, serta makanan tambahan adalah kerang ulir 0,68%, kepiting 0,28% dan serasah tumbuhan 0,16%
