Abstract

As one of the efforts to increase production of catfish culture, the Government of Tuban Regency launched the establishment of The Integrated Catfish Cultivation Center Area (ICACA) in Merakurak Sub-District in 2018. The existence of ICACA makes the program to increase catfish aquaculture more coordinated and increase production of catfish cultivation in Tuban Regency. ICCCA not only has an impact on the aquaculture business in Merakurak District, but also in other sub-districts in Tuban Regency. However, studies that explore the impact of ICACA on aquaculture in other areas are rarely reported. This study analyzes the impact of the existence of ICACA on cultivation business in Tuban District in Tuban Regency. This study uses a descriptive method with a mixed method approach (qualitative and quantitative). The results of this study indicate the factors that are the impact of ICACA in Merakurak District on the development of catfish cultivation in Tuban District. Based on the analysis carried out in this study, the implementation of ICACA in Tuban Regency, especially related to the effect of ICACA on catfish cultivation in Tuban District, needs to be directed to the application of sustainable aquaculture based on the empowerment of local community groups.

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

One of the aquatic ecosystems that are very susceptible to contamination is the reservoir ecosystem. Reservoirs have different characteristics from other water bodies because they receive continuous water input from the river that flows through them. The river water contains organic and inorganic materials that can cause pollution caused by various kinds of human activities. The pollutant that is currently getting more attention is microplastics. Hence, various ways are developed to monitor the presence of microplastics in environments. The biotic component that may adsorb and accumulate microplastics is microbes that formed biofilm matrices as a predominant habitat. This study analyzes the presence of microplastics in water and biofilm matrices in Lahor Reservoir. The water parameters (pH, dissolved oxygen, temperature, and flow velocity) were also measured. Samplings were carried out at three stations, namely station A (inlet channel), station B (middle), and station C (outlet channel). This study revealed that water quality parameters were still relatively good according to the environment's quality standards. The average value of microplastic abundance in water at station A was 0.0013 particles.mL-1, station B was 0.00083 particles.mL-1, and station C was 0.00072 particles.mL-1. The average abundance of microplastics in the biofilm at station A, station B, and station C was 7.55 particles.g-1, 7.26 particles.g-1, and 4.59 particles.gram-1, respectively. This study indicates that the abundance of microplastics in the biofilm in the Lahor Reservoir was thousands of times higher than in the water. According to the results of this study, the biofilm can be used as a biological agent in monitoring the presence of microplastics in aquatic ecosystems such as the Lahor Reservoir, East Java, Indonesia. Keywords: Aquatic Ecosystem, Biofilm, Microbial Ecology, Microplastics, Water Pollutant.

Abstract

Biofilm is the dominant habitat for aquatic microbes that can grow in various aquatic conditions, including environments with extreme conditions. One of the extreme conditions found in aquatic ecosystems is a hypersaline environment. As part of aquatic biological resources, microbes can also live in this environment. However, although it is the predominant habitat of microbes, biofilms in hypersaline environments have yet to be widely explored. Understanding biofilms in hypersaline environments, especially salt ponds, will increase knowledge about microbial biofilms. The knowledge can open opportunities for using microbes as aquatic resources, such as aquaculture or environmental biotechnology. This study analyzed microbial abundance in biofilms and water in hypersaline environments. The water is from salt ponds on the South Coast of Malang Regency, Indonesia, with different salinity levels (2%, 25%, and 40%). Microbial abundance was analyzed using the culture method using several culture media (Modified Nutrient Agar, Modified Total Plate Agar, Mannitol Salt Agar, and Casein Medium Agar). The substrate for biofilm growth is HDPE, often used as a bottom coating for salt ponds and shrimp ponds. Moreover, this study also analyzed water quality parameters (pH, dissolved oxygen, turbidity, conductivity, total dissolved solids, temperature) during the biofilms' forming process. The results of this study indicate that the abundance of good microbes that grow in the biofilm or the water around the biofilm is strongly influenced by the type of media used for culturing. The main composition of the most influential media is peptone. The density of microbes in the biofilm is hundreds to thousands of times higher than that in the surrounding water. The results of this study also show that the presence of microbes in both water and biofilm affects the water quality properties in hypersaline environments. Keywords: aquatic ecosystem, biofilm, hypersaline, microbial ecology.

Abstract

Efisiensi sistem aerasi menjadi aspek krusial dalam budidaya perikanan skala kecil, terutama untuk menjaga kadar oksigen terlarut atau Dissolved Oxygen (DO) tetap optimal. Penelitian ini bertujuan membandingkan performa dan efisiensi energi aerator diffuser dan pompa sirkulasi dalam meningkatkan DO pada kolam fiber 1000 L selama 24 jam, dengan kondisi DO awal rendah. Dua perlakuan (P1: aerator diffuser dan P2: pompa sirkulasi) masing-masing diulang tiga kali, serta satu kontrol tanpa perlakuan. Hasil pengukuran DO dianalisis menggunakan ANOVA satu arah dengan uji lanjut BNT. Hasil menunjukkan bahwa terdapat perbedaan yang signifikan (p < 0,05) antar perlakuan. Aerator diffuser (ΔDO = 3,50 mg/L) memberikan peningkatan DO tertinggi dan efisiensi energi 4,17 mg/L per kWh, lebih baik dibanding pompa sirkulasi (ΔDO = 2,70 mg/L; 3,21 mg/L per kWh). Kontrol menunjukkan penurunan DO alami sebesar 0,72 mg/L. Temuan ini menunjukkan bahwa aerator diffuser lebih efektif dan efisien secara energi dalam meningkatkan DO, serta lebih cocok diterapkan pada unit budidaya skala kecil
