Fish fermented products are popular products among 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 on the variety of the final products quality. One strategy to overcome this problem is by adding a potential lactic acid (LAB), a good bacterium, in the fermentation process. We have conducted a screening of LAB from several local Indonesian fermented fish products namely Pakasam and Wadi. The first screening collected 28 isolates which characterized as LAB from Gram stain and catalase activity. The second screening was done to screen a LAB which possess antibacterial activity against common contaminant bacteria namely Staphylococcus aureus ATCC 6538, Salmonella sp. 230C, Escherichia coli 563 B, Citrobacter freundii CK1, Klebsiella sp. CK2, and Morganella morganii TK7. Among those 28 isolates, we selected one isolate with the highest antibacterial activity and successfully identified molecularly as Weisella sp. GMP 12. Further isolation of antibacterial substances targeted bacteriocin showed a good inhibition to Staphylococcus aureus ATCC 6538 with 3694 AU (Activity Unit), Salmonella sp. 230C with 2254 AU, Citrobacter freundii CK1 with 3166 AU but not to E. coli 563 B. This finding concluded that Weisella sp. GMP 12 isolated from Pakasam could be a potential candidate as a starter in the production of fermented fish products to enhance its quality.

ABSTRACT
The exploration of vegetable tanning’s natural resources is fascinating as an alternative to basic chromium sulfate for its natural abundance and considerable environmental impact. In this work, an attempt has been made to extract vegetable tannin from Caesalpinia sappan L. bark using water as a solvent with different levels of temperatures and incubation times. The highest yield efficiency was observed at 80 °C for 4 hours. The presence of tannin content and polyphenolic compounds were screened by the phytochemical analysis using Iron (III) chloride (FeCl3), sodium hydroxide (NaOH), and ensured by the thin layer chromatography (TLC), and the Fourier transform infrared (FTIR). The extracts were then determined by percentage of extract yield, phytochemical, tannin type, moisture, total solids, and tannin characteristics. The findings indicate that the extract of Secang contains 4.98±0.28% total moisture, 95.02 ± 0.28% total solids, and 72.12 ± 2.81% total soluble solids, 52.28 ± 1.79% tannins, and 19.84 ± 1.41% non-tannin. Moreover, Fourier transform infrared (FTIR) analysis revealed a clear functional group within Caesalpinia sappan L., as evidenced by the type of tannin that is condensed. The TLC assay exhibited a considerable intensity under UV lights. It included several shades of light blue and blue, which could indicate the presence of secondary metabolites and tannin. Compared to mimosa, as the commercial
standard for tanning agents in the leather industry, Caesalpinia sappan L. presents promise as an eco-friendly substitute for basic chromium sulfate and a new alternative source of vegetable tannin for the leather industry.

Antibiotic resistance genes (ARGs) have recently become an emerging environmental contaminants. The aquatic environment, such as a river has already become the most polluted environment and can be a driver of ARGs. The water from irrigation canal has the potential to become a hotspot of ARGs through contamination from river pollutants carried along to the irrigation canal. However, the information regarding the cross-contamination of ARGs in fish farming systems integrated with irrigation canal in Indonesia needs further study. This study investigated the occurrence of ARGs sulfonamide (sul1), tetracycline (tetA), beta lactam (blaGES), and multi drug resistance (mexF) from body water samples along the irrigation canal and aquaculture ponds which utilize irrigation water for cultivation. Sampling sites are located in the Kulon Progo Regency (Indonesia) and samples were taken during the rainy season. Gene amplification was performed using Multiplex PCR. The results showed that sul1, tetA, and blaGES were detected in 67%, 63%, and 55% of all samples. Meanwhile, mexF was only found upstream and downstream irrigation canals, which accounted for 25% of the total samples. The results of this study indicated that the Sapon Irrigation Canal has the potential to cause the spread of antibiotic resistance genes.

Abstract
Lung cancer is a malignant tumor that attacks the lungs generated by carcinogenic free radicals such as cigarette smoke. Seaweed contains bioactive compounds that have the potential to reduce cancer-causing free radicals. This study aimed to determine the phytochemical content and cytotoxic activity of Halimeda tuna seaweed extract against lung cancer cells (A549). The H. tuna sample was macerated using methanol for 24 h. Cytotoxic test of H. tuna crude extract used the MTT test against A549. The crude extract was phytochemically tested and analyzed using gas chromatography–mass spectrometry (GC-MS). The results showed that the H. tuna crude extract had cytotoxic activity against A549 with an IC50 value of 2771 µg/mL. The phytochemical test showed that H. tuna crude extract contained flavonoids and steroids. showed the presence of fatty acid compounds including palmitic acid, oleic acid, myristic acid, palmitoleic acid and stearic acid. Based on the results can be concluded that H. tuna extract had cytotoxic activity against A549 with low cytotoxicity to be used as a chemo-preventive agent.

Background
Strategies to increase body resistance and prevent disease in aquaculture include using vaccines, antibiotics, and probiotics. Today, the use of antibiotics with natural ingredients is becoming a trend. Sargassum sp is a natural ingredient that contains high antioxidants and antibiotics.
Methods
This research was conducted from March to May 2022 at the Biotechnology Laboratory, Faculty of Fisheries and Marine, Universitas Riau, in two stages: 1) the sensitivity of extracts of Sargassum sp. and 2) the application of Sargassum sp. extract orally in tilapia (O. niloticus). The parameters measured were clear zone, minimum inhibitory concentration, LD50 test of leaf extract of Sargassum sp. in tilapia (O. niloticus), hemoglobin levels, hematocrit, total leukocytes, total erythrocytes, leukocyte differentiation, and survival rate. Data on hematology parameters were tabulated and analyzed using a One-Way ANOVA followed by a Student Newman Keuls (SNK) test when deemed necessary.

Caulerpa lentillifera seaweed comprises several bioactive compounds that possess health-promoting properties, which make it suitable for incorporation into food items, including yogurt. The purpose of adding seaweed to yogurt is to enhance its flavor and boost its antioxidant activity. The objective of this study was to determine the optimal concentration of C. lentillifera seaweed to evaluate its chemical, microbiological, and antioxidant properties, as well as to assess the level of consumer acceptance of yogurt. To achieve this, seaweed yogurt was prepared by incorporating C. lentillifera seaweed at concentrations of 0, 5, 10, and 15% (v/v), and the pH, lactic acid, lactic acid bacteria, total phenols, and antioxidant activity (using the DPPH method) were analyzed. In addition, the level of consumer acceptance was evaluated. The findings of this study demonstrated that disparities in the amounts of C. lentillifera seaweed affected the chemical and microbiological traits, including total phenols, antioxidant activity, and consumer preferences for yogurt. The optimal treatment was achieved with the addition of 5% seaweed at a pH level of 3.97±0.035, lactic acid content of 1.08±0.09%, lactic acid bacteria count of 1.74×10^8 cfu/mL, and total phenol content of 39.62±0.49 mg GAE/g. Additionally, the antioxidant activity value was 39.32±0.45%, and the hedonic values for color (3.64±0.98), aroma (3.59±0.83), texture (3.44±0.91), and taste (3.45±1.16) were also favorable. According to the proximate analysis, which evaluated the moisture, protein, fat, and ash content of seaweed yogurt, the results were consistent with SNI 2981:2009. Furthermore, the inclusion of C. lentillifera in yogurt production enhanced both its flavor and antioxidant activity.
