Abstract
Fish fermented products are popular products among the coastal community in Indonesia. Generally, the products are naturally produced with the addition of salt without any selection of the bacterial community. This situation resulted in a variety in the quality of the final products.One strategy to overcome this problem is by adding a potential lactic acid (LAB), a good bacterium, tothe fermentation process. We have conducted a screening of LAB from several local Indonesian fermented fish products,includingPakasamand Wadi. As many as 28 isolates were successfully obtained from the first step of screening, which was characterized as LAB by Gram stain and catalase activity. The second screening was done to screen a LAB that possessed antibacterial activity against common contaminant bacteria,namely Staphylococcus aureusATCC 6538, Salmonellasp. 230C, Escherichia coli563 B, Citrobacter freundiiCK1, Klebsiellasp. CK2, and Morganella morganiiTK7. Among those 28 isolates, we selected one isolate with the highest antibacterial activity and successfully identified molecularly as Weisellasp. GMP 12. Further isolation of antibacterial substances targetingbacteriocin showed a good inhibition to Staphylococcus aureusATCC 6538 with 3694 AU (Activity Unit), Salmonellasp. 230C with 2254 AU, Citrobacter freundiiCK1 with 3166 AU but not toE. coli563B. This finding concluded that Weisellasp. GMP12 could be a potential candidate as a starter to be used in the fermented fish products to enhance its quality.

Dalam kuliah tamu yang diselenggaran tersebut, seluruh mahasiswa tampak antusias dalam memperhatikan dan berdiskusi. Diharapkan dengan adanya kuliah tamu tersebut, mahasiswa maupun dosen dapat memperoleh insight baru terkait industri maupun juga ilmu dan teknologi dari luar negeri.
Dalam kunjungan ke Thailand, tim dosen juga berkesempatan untuk mengunjungi Fakultas Perikanan, Kasetsart University. Dalam kunjungan tersebut, tim dosen berdiskusi dengan Assistant Professor Wanwimol Klaypradit terkait dengan penelitian terkini yang dilaksanakan di Kasetsart serta peluang kerja sama seperti pengiriman mahasiswa pertukaran pelajar maupun studi lanjut.
Dalam kuliah ini, praktisi yang diundang memberikan penjelasan teori terkait praktik sanitasi dan higienen yang dilaksanakan di perhotelan. Selain secara teori, dilaksanakan juga praktik lapang yang bekerja sama dengan UC hotel dan Wisma MM UGM yang merupakan hotel bintang 3 di lingkungan UGM. Di akhir kegiatan, seluruh mahasiswa mempresentasikan temuan yang ada dilapangan serta memberikan solusi jika ditemukan ketidak sesuaian dalam penerapan sanitasi dan higiene tersebut.
Dalam pidatonya, Prof. Amir menjelaskan terkait potensi rumput laut terutama rumput laut coklat untuk dapat dimanfaatkan sebagai bahan pangan fungsional. Hadir dalam pidato tersebut beberapa tamu penting antara lain Ketua Masyarakat Pengolahan Hasil Perikanan Indonesia Prof. Nurjanah, Direktur Pengembangan Standar Agro, Kimia, Kesehatan dan Halal, Badan Standarisasi Nasional, Heru Suseno, S.Pi., M.T., pejabat struktural di lingkungan Kementerian Kelautan dan Perikanan, pejabat struktural dilingkungan Dinas Kelautan dan Perikanan Provinsi DIY dan Kabupaten Kulonprogo, serta tamu lain dari berbagai Universitas dan lembaga.

Abstract
Seaweed belongs to marine biota and contains nutrients and secondary metabolites beneficial for health. This study aimed to determine the antidiabetic activity of extracts and fractions of green seaweed Halimeda tuna. The H. tuna sample was extracted with the maceration method using methanol and then partitioned using ethyl acetate and water to obtain ethyl acetate and water fractions. The methanol extract, ethyl acetate fraction, and water fraction of H. tuna were tested for their inhibitory activity against α-amilase and α-glucosidase. The methanol extract and the fractions with the highest inhibitory activity were phytochemically tested and analyzed using gas chromatography–mass spectrometry (GC-MS). The results showed that the ethyl acetate fraction (IC50 = 0.88 ± 0.20 mg/mL) inhibited α-amylase relatively similar to acarbose (IC50 = 0.76 ± 0.04 mg/mL). The methanol extract (IC50 = 0.05 ± 0.01 mg/mL) and the ethyl acetate fraction (IC50 = 0.01 ± 0.00 mg/mL) demonstrated stronger inhibitory activity against α-glucosidase than acarbose (IC50 = 0.27 ± 0.13 mg/mL). Phytochemical testing showed that the methanol extract and the ethyl acetate fraction contained secondary metabolites: alkaloids, flavonoids, steroids, and phenol hydroquinone. The compounds in methanol extract predicted to have inhibitory activity against α-amylase and α-glucosidase were Docosanol, Neophytadiene, Stigmasta-7,22-dien-3-ol,acetate,(3.beta.,5.alpha.,22E), Octadecanoic acid,2-oxo-,methyl ester, and phytol, while those in the ethyl acetate fraction were n-Nonadecane, Phytol, Butyl ester, 14-.Beta.-H-pregna, Octadecenoic acid, and Oleic acid.
