There is a growing need for new antibacterial agents, in particular because many antibiotics are becoming ineffective due to the emergence of resistant bacterial strains. Soft corals of the Genus Sinularia, Family Alcyoniidae, have potential as a source of terpenoid and steroid compounds with antibacterial activity. These corals may vary in external morphology (shape, colour, size).The aim of this research was to identify extracted fractions with high antibacterial activity. Sinularia sp. specimens were extracted, fractionated based on solvent polarity, and tested for antibacterial bioactivity against pathogenic bacteria (Escherichia coli and Staphylococcus aureus). Antibacterial activity of the three fractions varied in strength. The dichloromethane fraction showed strong antibacterial activity, inhibiting S. aureus and E. coli growth at a concentration of 1 mg ml-1, while the ethyl acetate and ethanol fractions were effective at 10 mg ml-1 and 100 mg ml-1, respectively.

Mangroves are plants with good tolerance to salinity changes, developing a chemical defense system with pharmacological value. This study aimed to obtain a GC-MS profiles of Rhizophora apiculata mangrove leaves extract, which could scavenge DPPH radicals and inhibit the growth of Listeria monocytogenes, Salmonella typhimurium, and Pseudomonas aeruginosa. The research included sampling, extraction (maceration with MeOH:DCM), identification of chemical profiles using GC-MS spectra analysis, assaying for antibacterial activity (well diffusion method), and antioxidants (DPPH radical scavenging). Mangrove leaves sampling was carried out on Laemanta, Parigi Moutong, Central Sulawesi. Based on the leaves' characteristics and tips, the types of roots, fruits, and flowers, the mangrove leave samples were identified as R. apiculata. The GC-MS profiles of R. apiculata leaves extract was dominated by mome inositol (75.6%). The antibacterial assay showed at a concentration of 100 mg/mL of R. apiculata leaves extract showed weak to strong antibacterial activity, with the inhibition zone diameter of P.

Catfish is one of potential fisheries products in Central Sulawesi, but this fact is not in line with community consumption level. Catfishes contain protein and fatty acid which are good for health. The use of catfishes as fish chips become one of the way out to increase the community consumption level. This research aims at knowing the effect of catfishes protein concentration toward chemical content (water content, ash content) and organoleptics. The research result shows that the treatment of catfishes protein concentration is unsignifficantly effect the water and ash content, besides the result of hedonic test shows that the concentration signifficantly effect the taste, the smell and the texture of catfish chips but unsignifficanly effect the colour of it. The treatment by adding 200 g of catfish was being the panels’ most favorite treatment with a score of 4.5 or with the rounding 5 indicated as favored.

Bambu laut (Isis hippuris) merupakan salah satu organisme laut penyusun ekosistem terumbu karang yang dilaporkan berpotensi sebagai sumber bahan bioaktif. Bambu laut mengandung bioaktif polioksigenasi steroid, hidrokarbon, fenol dan asam lemak. Penelitian ini bertujuan mengonfirmasi komponen bioaktif dari ekstrak bambu laut. Sampel bambu laut dikoleksi dari perairan Kabupaten Donggala, Sulawesi Tengah, dengan kondisi cuaca cerah. Pada sampel bambu laut dilakukan proses ekstraksi (maserasi MeOH : DCM), skrining komponen bioaktif (metode Harborne), dan determinsi kandungan total alkaloid (ekuivalen kafein - CE), fenol (ekuivalen asam galat - GAE), flavonoid (ekuivalen kuersetin - QE), dan steroid (ekuivalen kolesterol - ChE). Hasil skrining komponen bioaktif menunjukkan ekstrak bambu laut (I. hippuris) mengandung sejumlah komponen alkaloid, fenol, steroid dan flavonoid. Ekstrak bambu laut mengandung alkaloid 11,61 ± 0,24 mg CE.g-1 ekstrak kering; fenol sebesar 18,92 ± 0,24 mg GAE.g-1 ekstrak kering; flavonoid sebesar 21,24 ± 0,28 mg QE.g-1 ekstrak kering; dan steroid sebesar 36.94 ± 1.39 mg ChE.g-1 ekstrak kering. Penelitian ini mengonfirmasi keberadaan komponen bioaktif ekstrak bambu laut (I. hippuris) yang dikoleksi dari perairan Sulawesi Tengah. Hasil skrining komponen bioaktif menunjukkan kehadiran komponen alkaloid, fenol, steroid dan flavonoid. Oleh karena itu, perlu diidentifikasi lebih lanjut senyawa bioaktif (diduga turunan steroid, alkaloid dan fenolik) yang terkandung dari ekstrak bambu laut.

Tomini Bay has very large fishery potential, skipjack tuna (Katsuwonus pelamis) is very abundant in PPI Paranggi. Availability of skipjack tuna which irequires a diversification of processed fishery products made from skipjack tuna. Some processed fishery products that are quite well known among the public are dim sum and satay (sate lilit). The method of implementing this activity is based on the persuasive-educative-communicative-participatory method. This research method with the principle of andragogy (education for adult) used as a guide. Based on the public service that has been carried out, it shown that the activity participants who came from women fishermen from Paranggi village, totaling 10 people, gave a positive response, this can be seen from the participants have been able to practice to make a processed dim sum and satay (sate lilit), while participants also showed an interest in making these preparations at home.
