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.

Abstract

Penelitian ini bertujuan untuk mengeksplorasi pengaruh aplikasi probiotik Bacillus spp. terhadap pembentukan biofilm dan kualitas air pada media budidaya udang vaname (Litopenaeus vannamei). Penelitian dilakukan secara eksperimental menggunakan akuarium berkapasitas 12 liter yang dilengkapi substrat HDPE sebagai media pembentukan biofilm. Parameter kualitas air yang diamati meliputi suhu, pH, oksigen terlarut (DO), salinitas, dan amonia (NH₃). Pengukuran dilakukan secara berkala selama 168 jam. Hasil penelitian menunjukkan bahwa aplikasi probiotik Bacillus spp. secara signifikan memengaruhi penurunan kadar amonia dan peningkatan ketebalan biofilm. Suhu dan pH berada dalam kisaran optimal, yaitu 28–30°C dan 7,5–8,5, yang mendukung pertumbuhan udang vaname dan aktivitas probiotik. Penurunan kadar amonia terlihat sangat signifikan, dari kondisi awal 3,9 mg/L menjadi <1 mg/L pada perlakuan probiotik. Pembentukan biofilm yang signifikan pada substrat HDPE menunjukkan bahwa probiotik mendukung terciptanya habitat mikroorganisme yang stabil, sehingga efektif dalam proses degradasi senyawa toksik seperti amonia. Pembentukan biofilm yang stabil dan Bacillus spp. mendukung proses bioremediasi serta menjaga kualitas air, sehingga menciptakan lingkungan yang optimal untuk pertumbuhan dan produktivitas udang vaname. Stabilitas biofilm ini juga berperan dalam menjaga keseimbangan ekosistem mikroba pada media budidaya. Penelitian ini menegaskan bahwa aplikasi probiotik Bacillus spp. memiliki potensi dalam meningkatkan kualitas air dan mendukung pengelolaan limbah seperti amonia, dalam sistem budidaya udang vaname. Temuan ini menunjukkan bahwa probiotik Bacillus spp. berpotensi dalam mendukung produktivitas budidaya.   This study aims to explore the effect of probiotic Bacillus spp. application on biofilm formation and water quality in vaname shrimp (Litopenaeus vannamei) culture media. The study was conducted experimentally using a 12-liter aquarium equipped with HDPE substrate as a medium for biofilm formation. Water quality parameters observed included temperature, pH, dissolved oxygen (DO), salinity, and ammonia (NH₃). Measurements were taken periodically for 168 hours. The results showed that the application of probiotic Bacillus spp. significantly affected the decrease in ammonia levels and the increase in biofilm thickness. Temperature and pH were within the optimal range of 28-30°C and 7.5-8.5, which favored vaname shrimp growth and probiotic activity. A significant decrease in ammonia levels was observed, from the initial condition of 3.9 mg/L to <1 mg/L in the probiotic treatment. Significant biofilm formation on HDPE substrate indicates that probiotics support the creation of a stable microorganism habitat, making it effective in the degradation process of toxic compounds such as ammonia. Stable biofilm formation and Bacillus spp. support the bioremediation process and maintain water quality, creating an optimal environment for vaname shrimp growth and productivity. This biofilm stability also plays a role in maintaining the balance of the microbial ecosystem in the culture medium. This study confirms that the application of probiotic Bacillus spp. has a positive effect on the growth of vaname shrimp.
