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 one of the marine mineral products that has great potential in Indonesia. Salt production in Indonesia is mostly located on the island of Madura and the north coast of Java. Indonesia still imports salt to meet salt needs, especially for industrial salt needs. In increasing national salt production, one of the strategic steps that need to be taken is to increase the area of ??salt ponds in Indonesia. To increase the area of ??salt land, one important strategy is to open salt ponds outside the North Coast of Java and Madura Island. One alternative location is the beaches in the southern region of Java Island. Salt production on the South Coast of Java has not been done much. On the South Coast of Malang Regency, there is no salt production business. The creation of salt production in the South Coast of Malang Regency needs to be based on an analysis of market potential. This study aims to analyze the market potential of salt commodities in the South Coast of Malang Regency. This study is the first study to analyze the market potential for the development of salt production in the South Coast of Malang. The results of this study indicate that the main market potential for salt production in the South Coast of Malang is salt for fishery activities and salt for livestock. In addition, there is a potential market for salt education activities and consumption salt. Based on the results of this study, the development of the salt commodity market in the South Coast of Malang can be developed with a Niche Marketing approach.

Abstract

The Metro River flows from upstream to downstream across East Java to support several human activities such as household, toilets, or agriculture. The utilization of water rivers must be balanced with water quality monitoring so that the quality of the water can be monitored. This study aims to analyze the abundance of microplastic in the Metro River. Moreover, the water parameters (pH, dissolved oxygen, temperature, flow velocity) were also measured. Sampling was carried out at three different stations, namely station 1 representing the agricultural activity area, station 2 representing the household activity area, and station 3 representing industrial activity. This study shows the abundance of microplastics in biofilm matrices and surrounding river water. The types of the microplastics are fibers, fragments, and films. The total abundances of microplastics in river water ranged from 0.8 - 1.61 particle.mL-1, while the biofilm matrices ranged from 7.4 to 9.5 particle.gram-1. The results of water quality parameters at all stations are still relatively good compared to quality standards. To the best of our knowledge, this study was the first study that reports the microplastics in the water of and inside biofilm formed on Metro River.

Abstract

Salt is an essential commodity that is widely used for consumption and industrial purposes. One of the main factors determining the success of this salt production is the suitability of the salt production location. However, there has been no analysis of the suitability of salt production locations in salt production centers in East Java. This study aims to analyze the suitability level of the location of salt production centers for the salt production process using the Salt Location Suitability Index (IKG). The areas analyzed in this study are salt production centers in Sampang Regency, Probolinggo Regency, Gresik Regency, and Tuban Regency. The IKG analysis is prepared based on nine suitability parameters: rainfall, soil permeability, soil type, duration of exposure, humidity, wind speed, air temperature, evaporation rate and saturation level of raw material water. The IKG analysis results can also be used as a basis for recommending alternative technologies that need to be applied to increase salt production. The results of this study indicate that the locations of salt production in Sampang District, Probolinggo Regency and Tuban Regency, which are the focus of this study, are in the Very Appropriate category (more than 85%), while the locations in Gresik Regency are in the Sufficiently Suitable category (80-84 %). Based on the results of this study, all the locations that are the focus of this study are suitable for further development of salt production.

Abstract

Desa Simo memiliki luas wilayah 268,85 ha dengan 23% wilayahnya berupa lahan pertanian dan sebagian wilayah berupa bentang alam lainnya yang menyimpan potensi besar yang belum termanfaatkan secara optimal terutama guna pembangunan pertanian. Oleh karena itu, dilakukan kegiatan pemberdayaan masyarakat menggunakan metode Asset Based Community Development (ABCD). Praktik dalam kegiatan terfokus pada, 1) pengenalan dan perbanyakan agens hayati, 2) pembuatan kompos dari limbah ternak, 3) pembudidayaan ikan yang baik. Dengan adanya kegiatan tersebut diketahui pemahaman petani di desa Simo mengenai pemanfaatan beberapa potensi desa yang dapat dioptimalkan dalam pertanian mengalami perubahan. Masyarakat petani setempat mulai mengenal dan bahkan memperbanyak agens hayati sebagai pengendali hama dan penyakit tumbuhan, memanfaatkan kotoran ternak sebagai bahan baku kompos, serta mengelola kolam sebagai pertumbuhan dan perkembangan ikan.
