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

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

Abstract

Catfish is an aquaculture commodity that has great potential to be developed in various regions in Indonesia. The success of catfish cultivation is primarily determined by creating a suitable environment for catfish. One way to create a suitable environment for catfish cultivation is the Recirculation Aquaculture System (RAS). In applying RAS, the presence of organic matter in the pond is controlled so the pond water can be reused. The presence of organic matter in pond water is determined mainly by the activity of bacteria in the water. These bacteria are actively involved in the pond's residual organic matter degradation process. Therefore, the total number of bacteria in the water can be one of the essential parameters in the RAS. The method widely used to calculate the abundance of bacteria is counting the number of bacteria based on bacterial culture method. However, the bacteria that can be cultured are only a small part of the bacteria in the water, so the abundance value obtained does not reflect the actual bacterial population. Therefore, it is necessary to analyze the abundance of bacteria using a method closer to the actual abundance value, such as the environmental DNA (eDNA) analysis. This study aims to analyze the abundance of bacteria in water in catfish aquaculture with RAS using the eDNA method. In addition, this study also analyzes water quality data (temperature, pH, Dissolved Oxygen). This study's results indicate that the water temperature value in catfish ponds ranges from 28.0 to 29.0 °C, the average pH value is 7.7, and the dissolved oxygen is between 5.7 - 6.2 mg/L. The water quality analysis results indicate that RAS can maintain optimum conditions in the catfish cultivation process. This study also showed that the total microbial abundance value at the beginning of cultivation was 1.68 × 107 cells/ml, and on day 30, it was 3.6 × 106 cells/ml. The dynamic of bacterial densities in this study may indicate that this system can maintain the stability of the microbial community.

Abstract

Salt is an essential commodity for both domestic use and industrial applications, with East Java Province in Indonesia playing a crucial role in national salt production. Traditional salt production methods, primarily based on natural evaporation, face challenges due to seasonal factors, particularly during the rainy season. This study investigates the environmental conditions affecting the salt crystallization process in the Greenhouse Salt Tunnel (GST) technology. Field experiments were conducted at two sites, Tuban Regency on the North Coast and Malang Regency on the South Coast, where key parameters such as air temperature, water temperature, humidity, wind speed, and evaporation rates were monitored three times daily. The findings showed that water temperatures within the GST ranged from 31 to 38°C on the North Coast and 26 to 38°C on the South Coast. Wind speeds varied between 1.5–2.4 m/s on the North Coast and 0.4–1.0 m/s on the South Coast, while humidity levels ranged from 54 to 80%. The GST system achieved a salt production rate of 6.4 kg/m² with NaCl content exceeding 94%, a significant improvement over traditional methods, which yield less than 70% NaCl. These results demonstrate that GST technology enhances both the quality and quantity of salt production, though design modifications are needed to address the dynamic coastal environment.

Abstract

Purpose: This community service initiative introduces an innovative solution combining venturi pump system technology and protein skimmer to enhance water quality, production efficiency, and sustainability in round tank-based white shrimp farming. The protein skimmer helps reduce dissolved organic matter and supports the maintenance of dissolved oxygen (DO) levels, both essential for shrimp survival. Methodology/approach: The approach includes participatory planning, Focus Group Discussions, the induction of venturi aerator and protein skimmer combination, socialization and technical training, technology demonstration (including water quality monitoring), partner assistance, and continuous monitoring and evaluation. The implementation partner is CV Nusantara Agro Mandiri, located in Tuban. Results/findings: The technology application led to an average increase in DO by 3 mg/L due to the venturi pump, and a reduction of total dissolved solids (TDS) by 400 mg/L with the help of the protein skimmer. These improvements supported better shrimp growth, with an average daily weight gain of 0.1 grams. Conclusion: Integrating venturi pump and protein skimmer technologies provides an effective means to improve water quality and enhance shrimp growth in round tank systems. This contributes to more stable and sustainable aquaculture environments. Limitations: Wider-scale implementation is required to test the technology under more diverse environmental and water quality conditions. Cost efficiency remains a key concern for broader adoption by farmers. Contribution: This technological combination offers a valuable strategy for improving cultivation environments and enhancing the productivity. Contribution to SDGs: This initiative supports SDG 2: Zero Hunger, SDG 14: Life Below Water, and SDG 17: Partnerships for the Goals.
