Abstract

AbstractUsed plastic bottles can be used for biofilter media, as microorganisms may attach in the bottle surface. To understand the effectiveness of the number of plastic bottles in the anaerob tank in reducing BOD5 and COD in laundry waste, a research has been done in October-December 2019. There were 3 treatments applied, namely P1 (25 bottles,  11.540 cm2 surface area),  P2 (50 bottles, 23.080 cm2 surface area) and  P3 (75 bottles,  34.619 cm2  surface area), with 3 replications in each treatments. The seeding time of the biofilm was 25 days and the retention time of the water was 12 hours. The effectiveness of BOD5 decrement was 48.4%, 61.1% dan 69.4% in P1, P2, and P3 respectively. While the effectiveness of COD decrement was 44.5%, 50% and61.8% in P1, P2, and P3 respectively. Based on data obtained, it can be concluded that the biofilter that was completed with plastic bottleswas able to reduce the BOD5 and COD in the laundry liquid waste and P3 provided the best result.Keywords: anaerob, bacteri, waste management, plastic bottle re-use

Abstract

AbstractMangrove serve as habitat for mangrove snail, including Cerithidea quadrata. Aresearch aims to understand the relationship between mangrove density and the abundance of mangrove snails (C. quadrata) has been conducted from May to July 2020 in the Sungai Asam Village, Indragiri Hilir Regency. A purposive sampling method was applied. There were 3 observation stations, and in each stations there were 3 transect lines. In  each transect line, there were 3 observation plots (10 x10 m) with 5 subplots (1x1 m) in each plot. The relationship between mangrove density and the abundance of mangrove snails was analyzed using a simple linear regression. The density of mangroves was around 844.44–1,100.00 (trees/ha), while the abundance of mangrove snails ranges from 6,222.22 to 13,333.33 (organisms/ha). Results shown that there was a very strong relationship between the mangrove density and snail abundance. The environmental condition in general is good and able to support the life of the mangrove snail. Keywords: Mangroves, gastropods, environmental parameters and Asam River

Abstract

 ABSTRACT             The quality of the shellfish used as raw material in processing greatly affects the smoothness of the processing process, and determines the quality of the resulting product. This study aimed to determine the organoleptic quality of lokan (Geloina erosa) soaked in vinegar (CH3CHOOH). The treatment factor was lokan soaked with a long soaking time of 60 minutes, 90 minutes and 120 minutes using 25% vinegar. Organoleptic data were analyzed by ANOVA and Turkey’s HSD test. The results obtained from the 3 test parameters obtained the highest organoleptic (appearance) value (7,27); lowest (6,63); the highest organoleptic (odor) value (5,49); lowest (5,27); the highest organoleptic (texture) value (7,44); lowest (6,24). That the vinegar immersion had an effect on the organoleptic quality of lokan.Keywords: Lokan, vinegar, organoleptic

Abstract

ABSTRACTThis study aimed to determine the consumer acceptance on thekernasproduced by using different cooking processes. The design used wasnon-factorial completely randomized design (CRD) with 3 kinds of the treatment, namely: fried in oil, coated with banana leaves and then barbequed, and coated with banana leaves then roasted. The results showed that the different cooking process on kernas had significant effects on the organoleptic values of appearance, aroma, taste and texture, as well as the value of water content, fat, protein and total phenols. The deep fried kernaswas the most favored by 65 of 80 panelists (61.25%), characterized by a distinctive brownish color, clearly visible of sago grains (7.7), with a distinctive fish flavor (7.7), had a crunchy-crispy texture butnot hard on the surface but softeninside(7.4), and had afish and savory tasted (7.7). The product was containing 56.14% water, 2.39% ash, 14.48% protein, and 7.09% fat, and containing0.07 ppmtotal phenols.Keywords:browning, kernas, mackarel tuna, sago,

Abstract

ABSTRACTSea grapes are a type of green algae that have not been widely used and are included in seaweed. Seaweed is reported as edible algae, has bioactive substances such as anti-bacterial, anti-fungal, anti-tumor, and can be used to treat high blood pressure and goiter. This study aimed to determine the antibacterial activity of methanolic extract of sea grapes (Caulerpa lentillifera) against Escherichia coli and Bacillus cereus bacteria. The research method for the preparation of sea grapes was by cleaning from all impurities so that sea grapes were free from all impurities, then extracted with 2, 4, and 6% methanol and analyzed descriptively. The test parameters were antibacterial activity and the diameter of the inhibition zone. The results showed that the methanol extract was classified as having antibacterial activity against Escherichia coli and Bacillus cereus bacteria. The concentration of 6% methanol extract had the highest value with an inhibition zone of 2.27% for Escherichia coli and 6.82% for Bacillus cereus. Keywords: Caulerpa lentillifera, Escherichia coli, Bacillus cereus
