Abstract

Seagrass ecosystems are inhabited by many species of benthic invertebrates, demersal and pelagic organisms that reside or stay temporarily in seagrass ecosystems. This research aimed to analyze the density of the macrozoobenthos in two different moon phases and to seek the contribution of each macrozoobenthic species in each research stations at seagrass beds. Sampling of the macrozonthic organisms was taken in three research stations of Panggang Island (west, east, and south) by using a 1 x 1 m of quadratic transect and a sediment corer with 10 cm in diameter. The data analysis statistically analysis data was carried out by finding out the similarity percentage of the species contribution using SIMPER test. Results of this research indicate that the discovered macrozoobenthos for two phases of moon are varied in each station. The total found macrozoobenthos during two moon phases are 28 and 11 species in the west station, 24 and 20 species in the east station, and 18 and 24 species in the south station, respectively. In the three stations, the two highest and the lowest species density of macrozoobenthos during the two moon phases namely are Cerithium salebrosum (283 ind/m2) and Cerithium punctatum (169 ind/m2); and Geotrochus multicarinatum (7 ind/m2). Moreover, the most contributor species of macrozobenthos in the seagrass habitat of the entire stations is Cerithium salebrosum.

Abstract

Kapang dapat tumbuh pada bahan pangan, sehingga bahan tersebut menjadi rusak. Berbagai kapang telah dilaporkan terdapat pada ikan sebagai kontaminan, bahkan pada ikan asap yang dilapisi pengawet alami (kitosan). Oleh sebab itu, penelitian ini dilakukan untuk melihat keberagaman kapang kontaminan pada ikan asap yang dilapisi kitosan setelah masa penyimpanan tertentu. Ikan asap dilapisi dengan kitosan 0,5; 1; 1,5; dan 2%. Ikan asap disimpan pada suhu ruang dan dilakukan pengamatan setiap hari hingga ikan tampak ada pertumbuhan kapang. Kapang yang tumbuh diisolasi dan dikarakterisasi morfologinya secara makroskopis dan mikroskopis. Selain itu, juga dilakukan perhitungan jumlah jenis dan koloni kapang yang tumbuh pada ikan asap. Hasil penelitian menunjukkan bahwa ikan asap dengan pelapisan kitosan 0,5% terdapat 4 isolat dengan jumlah koloni 17, pelapisan kitosan 1% terdapat 5 isolat dengan jumlah 23, pelapisan kitosan 1,5% ditemukan 4 isolat dengan jumlah koloni 8, dan pelapisan kitosan 2% terdapat 2 isolat dengan jumlah koloni 2.

Abstract

Smoked fish is one of the traditional fish processing through the process of open heat smoking. The water content in smoked fish is quite high. The high water content will facilitate the growth and development of decaying microbes. Some studies have reported that smoked fish after being stored for several days will be overgrown at any time, even smoked fish that have been coated with chitosan. Research objectives to analyze the characteristics of contaminants in smoked fish treated with chitosan. The research was conducted from November to December 2020 at FPIK UNIPAS Morotai Laboratory. The growth medium of the glyph uses potato extract (PDA), the isolation of the glyph from smoked cob fish, as well as the characterization of the glyph which includes macroscopic and microscopic characters. The data obtained is analyzed descriptively. The result is isolation was found five isolates of any time, namely isolates KU1, KU2, KU3, MG1, and KS1. Based on macroscopic and microscopic characterization, isolate KU1 such as Fusarium oxysporum, isolate KU2 such as Aspergillus niger, isolate KU3 such as Penicillium sp., isolate MG1 such as Aspergillus flavus, and isolate KS1 such as Acremonium sp.
