Abstract

The use of antibacterial from natural ingredients can as an alternative, one of them is seagrass Enhalus acoroides which is known to have inhibiting active compounds bacterial growth. Metabolites from seagrass are known to be biologically active is an important biomedical and can be used as a drug potential. The use of antibacterial from natural ingredients is alternative approach. Bacteria Salmonella typhi is a genus of gram-negative enterobacteria sticks that cause typhoid, paratyphoid, and foodborne diseases and resistant bacteria. Therefore, the purpose of this research was to analyze the activity test antibacterial on Enhalus acoroides seagrass against Salmonella typhi bacteria. The methods used in this study were seagrass extraction, phytochemical tests, and antibacterial activity tests. The results obtained from the research are crude extracts with solvents methanol, ethyl acetate and n-hexane with a concentration of 500 ppm was the most effective extract concentration in inhibiting bacterial growth Salmonella typhi with a weak category. Furthermore, characteristic Antibacterial crude extract of seagrass Enhalus acoroides was bacteriostatic. This study suggests that the influence of polarity types solvent on antibacterial activity of seagrass extract Enhalus acoroides against the growth of Salmonella typhi bacteria.

Abstract

Waste management by society not only reflects individual responsibility but also plays a crucial role in environmental sustainability and community welfare. This research aimed to understand society’s perception and behavior regarding domestic waste and its surrounding waters. Understanding societal behavior is the key to sustainable environmental management. Direct inquiry was conducted to the sample population of 25 respondents who represented various age, education, and cultural groups in the densely populated residential area surrounding the Brantas River in Dinoyo Ward. Field observations were done to take water quality parameters and monitor the residents’ behavior regarding waste management. The results indicated that 76% of respondents know the impact of river pollution, although most did not contribute actively to reducing their domestic waste volume. About 44% of respondents never saw anyone littering the river, which may be due to the regular waste pick-up system. This was supported by water quality parameters that did not demonstrate any sign of pollution, although high turbidity was indicated. Comprehension of the results of this study is hoped to inspire the ideas of solid intervention plans to increase awareness and decrease the negative impact of domestic waste on the Brantas River in Dinoyo Ward. Keywords: society perception and behavior, domestic waste management, aquatic environment, Brantas River

Abstract

Millennial Shrimp Farming (MSF) is an innovative cultivation system known for its efficient production methods and advanced technology. This study explores the economics aspects of cultivating vaname shrimp using MSF systems, with a focus on profitability and sensitivity. This research was carried out at the MSF CV Nusantara Agro Mandiri, using three cultivation ponds and one water reservoir. To assess business viability, the analysis carried out includes Total Cost, Total Revenue, R/C, Profit, BEP Unit, BEP Sales, PP, and ROI. The results indicate that this business is economically feasible, with a BEP Unit of 1,186 kg and a minimum BEP sales price of IDR42,279/kg, while the production reached 6,120 kg. The R/C value of 1.30 signifies efficiency and profitability. The business vulnerability, at 30%, exceeds the Indonesian state bank interest rate of 12%. With an ROI of 30% and a NPV of IDR382,662,975, along with Net B/C, R/C, IRR, and PP indicators (6.96; 1.3; 63%; and 1.6 years, respectively), this business can be classified as both feasible and profitable. In sensitivity analysis, white shrimp farming with the MSF system is a viable and profitable endeavor with a low level of sensitivity to fluctuations in feed prices and uncertain operational revenues.
