Abstract

Seawater is one of the potential resources in Indonesia. One of the commodities that can be produced from seawater is salt. Salt production in Indonesia is done mainly by evaporating seawater. However, weather problems are one of the obstacles to salt production. Alternative innovation to overcome weather problems in salt production is the Greenhouse Salt Tunnel (GST). The application of this innovation allows salt production to be carried out throughout the year. Most salt businesses in East Java are located on the north coast of East Java, while there is no salt production on the South Coast of East Java. One of the locations in East Java that can be used for salt production is the South Coast of Malang Regency. However, studies analyzing the need for innovation to create salt production in the South Coast of Malang Regency have never been reported. This study aimed to analyze the application of GST innovation to create salt production in the South Coast of Malang Regency. The methodologies were analyzing the suitability index of salt production sites, soil elevation analysis, wind direction and speed, and construction requirements for GST. The results show that Gajahrejo Village is very suitable for salt production. The salt production can be conducted using 12 GST constructions on a 2000 m2 area. According to the results of this study, salt production in the south coast area of Malang Regency can be created using the application of GST innovation.  Keywords: aquatic resources, greenhouse salt tunnel, solar salts; south coast of Java, technology innovation

Abstract

Produktivitas primer merupakan indikator utama kesehatan ekosistem akuatik, karena mencerminkan kemampuan perairan dalam menghasilkan biomassa. Penelitian ini dilakukan di kolam budidaya ikan UPT Laboratorium Sumberpasir. Tujuan dari penelitian ini adalah untuk membandingkan profil mingguan produktifitas primer antara kolam beton dan kolam tanah dengan pengambilan sampel mingguan selama delapan minggu, dan mengukur parameter seperti suhu, pH, oksigen terlarut (DO), nitrat, fosfat, klorofil a. Metode pengukuran produktivitas primer diukur menggunakan metode botol terang dan botol gelap. Hasil pengukuran menunjukkan bahwa kolam beton cenderung mengalami fluktuasi yang lebih besar dalam suhu dan pH dibandingkan dengan kolam tanah. Suhu pada kolam beton lebih tinggi, sedangkan kolam tanah lebih stabil. Tingkat DO di kolam tanah juga lebih tinggi, menunjukkan ketersediaan oksigen yang lebih baik untuk organisme air. Kolam beton menunjukkan kadar nitrat yang lebih tinggi pada awal pengukuran, yang secara bertahap menurun. Sebaliknya, kadar nitrat pada kolam tanah lebih stabil, namun lebih rendah secara keseluruhan. Demikian pula, konsentrasi fosfat dan klorofil-a pada kolam beton umumnya lebih tinggi, produktivitas primer pada kolam tanah awalnya lebih tinggi, namun kolam beton menunjukkan peningkatan produktivitas primer pada titik-titik tertentu. Secara keseluruhan, penelitian ini menunjukkan bahwa kolam tanah cenderung memberikan lingkungan yang lebih stabil bagi ikan, sedangkan kolam beton dapat mendukung produktivitas primer yang lebih tinggi dengan manajemen nutrisi yang tepat. Hasil ini memberikan wawasan penting bagi praktik budidaya ikan dalam memaksimalkan produktivitas dengan memperhatikan karakteristik masing-masing jenis kolam.   Primary productivity serves as a principal indicator of the health of aquatic ecosystems, as it reflects the capacity of these ecosystems to produce biomass. The present study was conducted in the fish farming ponds of the Sumberpasir Laboratory. The objective of this study was to compare the weekly profile of primary productivity between concrete ponds and earthen ponds. To this end, samples were taken on a weekly basis for a period of eight weeks, and a range of parameters were measured, including temperature, pH, dissolved oxygen (DO), nitrate, phosphate, and chlorophyll a. The primary productivity measurement method employed was the light bottle and dark bottle method. The results of the measurements demonstrated that the concrete ponds exhibited greater fluctuations in temperature and pH compared to the earthen ponds. The temperature in the concrete ponds was observed to be higher, while the soil ponds demonstrated greater stability. Furthermore, the earthen ponds exhibited higher levels of dissolved oxygen (DO), which indicates enhanced oxygen availability for aquatic organisms. The initial nitrate levels in the concrete ponds were higher than those in the earthen ponds, but they subsequently decreased. In contrast, nitrate levels in the earthen ponds exhibited greater stability, although they were overall lower. Similarly, phosphate and chlorophyll-a concentrations in concrete ponds were generally higher, primary productivity in earthen ponds was initially higher, but concrete ponds showed increased primary productivity at certain points. Overall, this study suggests that earthen ponds tend to provide a more stable environment for fish, while concrete ponds can support higher primary productivity with propernutrient management. These results provide important insights for fish farming practices in maximizing productivity by considering the characteristics of each pond type.

Abstract

Abstract Hydrocarbon contamination is one of the most significant environmental problems, including in the marine environment. Several methods, such as chemical and physical remediation, have been constructed to remediate pollutants but remain side effects and have a relatively high cost. Bioremediation is an alternative method for degrading contaminants due to its eco-friendliness and low cost. During bioremediation, the enzyme oxygenase is produced by bacteria to degrade pollutants. However, the oxygenation enzyme's activity and compound profile during this bioremediation process are still sparsely explored. This study aimed to analyze oxygenation enzyme activity and compound profiles during the hydrocarbon bioremediation process by bacterial consortia of Pseudomonas aeruginosa and Rhodococcus erythopolis. The materials of this research were the oxygenase enzyme activity, compound profile, and amount of BOD and COD during the bioremediation process. The results showed that the monooxygenase enzyme has activity between 0.257 and 3.859 U/mL. Meanwhile, the dioxygenase enzyme has activity between 0.579 and 5.402 U/mL. The final incubation compound profile found that Hexadecanoic acid methyl ester (C17H34O2) decreased by up to 47.66%. Moreover, BOD and COD reductions were 68.59% and 67.51%, respectively. This study concluded that oxygenation enzymes were produced to degrade pollutant compounds during the hydrocarbon bioremediation process. Further research is needed to improve the effectiveness of bioremediation by enhancing enzyme activity. Highlight Research The potential of hydrocarbon-degrading bacteria (Rhodococcus erythropolis and Pseudomonas aeruginosa) for pollutant degradation in the marine environment. Enzyme activity of hydrocarbon-degrading bacteria and degradation profile of pollutants. The dynamics of BOD and COD during the bioremediation process.

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 that concerns the livelihood of society and cannot be substituted by other commodities. East Java is the largest salt-producing center in Indonesia. The results of community salt production often still have NaCl content 95%. To achieve salt production results with NaCl quality 96%, research, and technology development are needed to eliminate impurities and improve the quality of the salt produced. One of the technologies being developed is the utilization of reservoirs and raw water filters. This research aims to analyze the application of reservoir and filter technology in improving the quality and quantity of salt production on the South and North Coasts of East Java using greenhouse salt tunnels. The results of this study indicate that the dynamics of environmental parameters and the quality of raw water on the South and North Coasts of East Java affect the results of the salt production process. The quality and quantity tests of salt with reservoir and filter application on the South Coast of East Java show NaCl quality of 98.13%, water content of 5.44%, and whiteness presentation value of salt 80.5% with production quantity of 7 kg/m². In trials on the North Coast of East Java, the salt quality was 98.25%, water content was 5.37%, and the whiteness percentage value of salt was 79%, with a salt production quantity of 7.8%. This research indicates that reservoir and filter technology can improve the quality and quantity of salt according to the characteristics of the South Coast and North Coast of East Java.
