Abstract

The various characteristics of catches and fishing gear provide distinct advantages for fishermen, but these characteristics can cause other problems, namely pressure on stock availability caused by an increase in the number of catches and the use of various types of fishing gear and the efficiency provided. There needs to be good management to handle this. The purpose of this research is to find out the clusterization (grouping) of fishing areas based on the catch and the type of fishing gear in which the results of this study are used as a reference in sustainable fisheries management. This research uses descriptive methods and case studies at PPP Bulu. The analytical method used is the Shannon-Wienner index of diversity (S-W,H'), Margalef richness (R') and clusterization. Clusterization was analyzed using the Hierachical Cluster Analysis (HCA) method to obtain the Euclidean distance. The results showed that the value of diversity has a range of 0-2 and the value of wealth has a range of 1-10. The results of the clusterization show that there are 3 clusters of fishing areas formed based on the catch, while no clusters of fishing areas are formed based on the type of fishing gear operated.

Abstract

The phylum Coelenterata, class Anthozoa, includes a group of marine living things known as corals. Corals feature a variety of incredibly gorgeous colors and patterns. The majority of the world's more than 70,000 coral species may be found in tropical marine environments. Due to its geographic setting, Indonesia has an extremely high level of coral diversity and is the world's largest exporter of ornamental coral. Demand on the market for natural ornamental corals is now rising, along with trends in the rate of industrial development. Allowing this industrial activity to grow will result in huge exploitation and put the coral reef environment at danger. Therefore, to quickly increase the number of corals, this research examined transplantation methods. The montipora and echinopora genera were the focus of this study. The Montipora capricornis coral sample from PT Tirta Samudra Bali had the highest growth rate of the Montipora genus corals there, with an average growth rate of 1,404 cm2/week. The highest growth rate of the Echinopora genus corals had an average growth rate of 0.362 cm2/week. As they have a 100% survival record, cultivation activities using the transplant method performed at PT. Tirta Samudra Bali are regarded as successful

Abstract

Crowds of flies will add to the burden of everyday life. Moreover, if the flies try to eat the fly, they will be caught in the trap placed in the container's open mouth. Therefore, the fly population at X Hospital, Tulung Agung, should be controlled to a non-hazardous extent. This study analyzes the practical design for catching flies in the temporary hospital waste collection area. Fly traps are designed based on design criteria. Where fly traps can be made of wood and wire mesh to form a cylinder, inside which the flytrap is placed cone-shaped wire mesh. The fly trap, which has a length of 165 cm, a width of 180 cm, and a height of 30 cm, will be applied in a closed container with a capacity of 6 m3 and dimensions of 3.3 meters in length, 1.8 meters in width and 1.2 meters in height. This eco-friendly fly trap is made using perforated anti-mosquito wire mesh and arranged on top of the container. At the same time, the flies obtained can be used according to the needs that will be used.

Abstract

Lamongan Regency has a fairly progressive fisheries sector with high fishing activity, such as the fishing industry and ports, especially in the Paciran and Brondong subdistricts. On the other hand, rapid fishing activities can also cause the entry of pollutants such as heavy metals and have the potential to reduce water quality in the area. The aim of this research is to analyze water conditions based on physical and chemical parameters as well as the distribution of dissolved heavy metal Hg and Pb in the fisheries industrial area and port of Lamongan Regency. The research was carried out using a purposive sampling method at seven stations along the waters of both Brondong and Paciran Districts. The data used in this research includes water quality parameters and dissolved heavy metal Hg and Pb. Analysis of heavy metal content was carried out in the laboratory using an Atomic Absorption Spectroscopy (AAS) instrument. The results showed that the heavy metal Hg at all stations was not detected by AAS because its concentration was very low. Meanwhile, the heavy metal Pb shows varying values at all stations with a range of 0.08 mg/L – 1.88 mg/L. The concentration of the heavy metal Pb at most location points has exceeded the limits set by Indonesian Government Regulations. The results of statistical analysis show that there is a relationship between temperature and pH and the concentration of the heavy metal Pb in water.

Abstract

Avicennia marina is a species of mangrove that has been studied extensively for its capability to uptake and accumulate heavy metals. Since Avicennia marina was found in the Wonorejo Mangrove ecosystem, which confirmed received anthropogenic inputs from Surabaya as the second largest city in Indonesia, the effectivity of bioaccumulation and translocation metals Cd, Zn, and Pb was studied. The sediments, roots, stems and leaves of Avicennia marina were collected in three sites in Wonorejo Mangrove Ecosystem, East Surabaya. The measurement of Cd, Zn and Pb was conducted by ICP-MS. To assess the effectiveness of accumulation and translocation capability, Bioconcentration Factor (BCF) and Translocation Factor (TF) were calculated. The results showed that the distribution of heavy metals Cd and Pb in the organs of the mangrove Avicennia marina exhibited distinct patterns. Although both of them are considered as non-essential elements, Cd tends to distribute evenly until leaves parts, while Pb tends to retain in the roots. In the case of Zn, as an essential element, the uptake was more intense compared to non-essential elements and mobilized until the leaves parts. Interestingly, once all metals reach the stem, they might transfer to the leaves as shown by TF values more than 1. Therefore, Avicennia marine has an effective defense mechanism in the presence of metals by regulating the accumulation and translocation of metals into detoxifying organs.

Abstract

The food industry with the fastest rate of growth in more than 50 years is the fisheries sector. The sector of aquaculture and capture has grown to be very promising. In order to support the success of this business, the aquaculture industry in freshwater and marine environments is currently progressing. In the larval stage, choosing fish feed that is of high quality is crucial. The primary food source for fish larvae to support the growth and development of farmed fish is natural feed with a high protein content. Numerous varieties of farmed fish and ornamental fish have been fed Tubifex tubifex, a natural silkworm food. Protein and fat content in this polichaeta class worms are respectively 66% and 12%. When farmed fish are growing and developing, the high protein content of these worms may serve as their primary source of protein. Several initiatives are currently being made to enhance worm protein quality by consuming more food that contains macro- and micronutrients. Agricultural waste that has fermented or decomposed, which is typically regarded as waste, has nutritional value that can be combined with mud or sand to keep worms for a while. The nurture of fish larvae or fry may one day be possible using silkworms.
