Abstract

Sponges are host organisms for various symbiotic microorganisms.  Various symbiotic microorganisms have been found in Sponges such as archaea, heterotrophic bacteria, cyanobacteria, green algae, red algae, cryptophytes, dinoflagellates, and diatoms. The objectives of the research were to isolate and identify teh Axinella sp. Sponge-symbiotic microoganisms such asbacteria, micro fungi, and yeast. Sponge-symbiotic microoganisms that have been isolated cosisted of 7 bacteria isolates, 3 micro fungi, and 2 yeast isolates. Result from this research showed that the genus of bacteria was Alteromonas, Bacillus, and 2 yeast isolates have not been to identified.

Abstract

Meretrix meretrix, Pholas dactylus and Babylonia spirata are potential fisheries commodity, but information about their nutritional values is still limited. This research was aimed to determine the chemical compositions of Meretrix meretrix, Pholas dactylus and Babylonia spirata. Proximate of Meretrix meretrix, Pholas dactylus and Babylonia spirata were analyzed using thermogravimetric, soxhlet and kjeldahl methods. Their amino acid composition and taurine content were analyzed using High Performance Liquid Chromatografy (HPLC). The moisture, ash, fat, protein and carbohydrate contents of Meretrix meretrix were 79.98%, 1.37 0.11 9.39 and 9.02 respectively; Pholas dactylus were 83.78%, 1.19, 0.11, 11.37 and 3.55 respectively; while Babylonia spirata 78.44, 1.20, 0.33, 17.38 and 2.65 respectively. Arginine was the highest essential amino acid found in Meretrix meretrix, Pholas dactylus and Babylonia spirata meat with values of 1.12%, 0.93 dan 2.50 respectively. Glutamic acid was the most abundant non-essential amino acid with the highest value of 2.24, 2.14 and 3.76. The limiting amino acid was histidine with the value of 0.25%, 0.18 and 0.34, respectively. The taurine content of Pholas dactylus meat (0.085%) was higher than the Babylonia spirata and Meretrix meretrix (0.067 and 0.062%, respectively).

Abstract

Agar adalah bentuk koloid dari suatu polisakarida kompleks yang diekstrak dari beberapa kelompok alga merah (Rhodophyceae). Salah satu pemanfaatan dari agar adalah sebagai media untuk pertumbuhan mikroba. Agar bakto adalah salah satu medium kultur yang digunakan untuk membantu menggelifikasi berbagai jenis larutan medium atau larutan kaldu (broth). Penambahan kitosan sebagai absorben pada proses pemurnian agar diharapkan dapat menghasilkan agar yang murni (refine agar) yang dapat digunakan untuk agar bakto sebagai media pertumbuhan mikroba. Tujuan dari penelitian ini adalah memodifikasi berbagai konsentrasi kitosan dan waktu proses absorbsi dalam pembuatan agar bakto sebagai media pertumbuhan mikroba. Penelitian dibagi menjadi dua tahap, yang pertama adalah tahapan proses isolasi kitin dan deasetilasi kitin menjadi kitosan dan penelitian utama yang dilakukan yaitu pembuatan agar bakto dengan menambahkan berbagai konsentrasi kitosan (0,5%, 1%, 1,5%) sebagai absorben terhadap agar yang dihasilkan dari Gracilaria sp. dan agar batang. Perlakuan kedua yang diberikan yaitu waktu proses absorbsi setelah dilakukan penambahan kitosan. Proses absorbsi yang dipilih 0 menit, 15 menit, 30 menit, dan 45 menit. Kombinasi perlakuan paling optimum untuk agar bakto berbahan baku Gracilaria sp. adalah pada konsentrasi kitosan 1% dengan lama pemanasan lanjutan ekstraksi selama 45 menit. Kombinasi perlakuan paling optimum untuk agar bakto berbahan baku agar batang adalah pada konsentrasi kitosan 0,5% dengan tanpa pemanasan lanjutan.Kata kunci: agar bakto, Gracilaria sp. , kitosan

Abstract

Local mussel (Pilsbryoconcha exilis) is one aquatic commodity that has high enough potential. Mussel shell is solid waste that has not been used optimally. The purpose of this research is to study the physical and chemical characteristics shells and mussel shell flour with the different of size and body length. The observed parameters include the physical characteristics of shells, yield, chitin, flour yield, degree of white, proximate contents, pH, minerals and mineral solubility determination of mussel shell flour. Mussel obtained from waters Situ Gede has length between 72-103 mm, 31-47 mm high and 13-34 mm thick. Mussel shells in all size contained chitin ranging from 0,72% to 0,75%. Mussel shell flour measuring < 90 mm 20% larger than the size of mussel ≥ 90 mm. Mussel shell flour measuring < 90 mm has a value of 5% degrees whiter than white shell size ≥ 90 mm. Shell flour has a water content between 1,19-1,2%, 93,14-93,34% of ash, 1,85-2,31% of protein, 0,66-0,72% of fat, carbohydrate by difference 2,62-2,94% with a pH range of 8,5-8,9. Mussel shell flour has a mineral content, respectively from the largest which are calcium, phosphorus and magnesium. The calcium and phosphorus mussels flour shell has an optimal value for solubility at pH 2. Mussel shells contained chitin ranged from 0,72% to 0,75%. Mussel shell size difference gave a significantly different effect on the physical characteristics of the mussel shell flour produced but did not influence significantly different to the chemical characteristics of the mussel shell flour produced.

Abstract

Golden apple snail (Pomacea canaliculata) has been known as rice corps pest due to high adaptability and reproductive power. Utilization of Pomacea canaliculata’s eggs as raw materials in the food and health industry is one of the efforts to eradicate the pest snail. This study was aimed to identify the active compounds contained in the extract pigments of Pomacea canaliculata’s eggs. The methods of this study were extraction of pigments using acetone and methanol, analyzing the active compound (secondary metabolite) qualitatively, TLC to determine pigment components and LC-MS/MS to identify active compounds semi quantitatively. The results showed that active compounds in the methanol extract contain 11 carotenoid pigments of xanthophyl group, two carotenoid pigments of carotene group, and 2 active compounds in nonpigmented form, whereas the acetone extract contain 11 pigmentcarotenoids of xanthophyl group and 2 compounds active in non-pigment form.
