Abstract

The purpose of this study was to determine the pattern of LAT ecdysis, especially the Freshwater Lobster Procambarus clarkii, aged 21 days to 66 days. In crustaceans, moulting is part of the growth mechanism. Changes in shape and size can only occur if the hard calcareous exoskeleton is removed before the new cuticles have hardened. Periodic moulting or ecdysis continues by separating the old cuticle from the new instar, this growth process takes place continuously. The moulting cycle can be divided into four stages, namely: proecdysis, ecdysis, metecdysis and intermoult. Moulting occurs when the LAT is 2 to 3 weeks old. Death often occurs in this period, death occurs due to cannibalism caused by moulting in LAT which does not take place simultaneously because each individual grows differently, thus allowing cannibalism to occur in other individuals who are molting. Process moulting in LAT may be standardized by administering the hormone Phytoecdysteroids given at the time of proecdysis. To find out proecdysis, you must first know the LAT ecdysis pattern. The results showed that the more often the LAT had molted, the longer the number of days needed for the LAT to experience the next moulting. This is because the size of the lobster is getting bigger so that energy is needed not only for activity and maintenance but also for growth.

Abstract

This study aims to determine the effect of several concentrations of chitin on the NSK population and to determine the microbes (fungi) that act as chitinolytic microbes. The hypotheses put forward are (1) the higher the concentration of chitin, the lower the NSK population, (2) there are microbes (fungi) that act as chitinolytic microbes. to the soil at high concentrations. The best treatment capable of suppressing the yellow cyst nematode population and increasing the fresh weight of tubers was 0.5% chitin concentration. The results of isolation of soil microbes (fungi) before planting found 5 fungi that are chitinolic and capable of degrading chitin in cysts, namely Trichoderma sp., Paecilomyces sp., Aspergillus sp., Verticillium sp. and Penicillium sp., while the observation of 100 hst showed an increase in the fungus Trichoderma sp. from one species to four species. Potato (Solanum tuberosum L.) is an important horticultural commodity in Indonesia which is currently an alternative food ingredient, as a source of protein-rich carbohydrates to support food diversification programs (Rukmana, 1997). One of the important pests that are troubling farmers potatoes, especially in Malang district, East Java, is the Yellow Cyst Nematode (NSK). According to a report from the Ministry of Agriculture, in Indonesia in 2003 the area of infected plants was estimated at 25% of the total area of 800 hectares of potato plants. Control has been carried out well biologically and chemically. Alternatives for biological control include using materials that are unfavorable for the nematode environment, namely through the use of chitin.

Abstract

The purpose of this study was to determine the effect of Bacillus firmus on the number of V. harveyi bacteria and the survival of the vanname shrimp (Litopenaeus vannamei). The main parameters in this study were the number of V. harveyi bacteria and the survival of the vanname shrimp (L. vanname), while the supporting parameters used were water quality including temperature, DO, pH and salinity The results showed the number of V. harveyi bacteria in the media maintenance of vanname shrimp after administration of B. firmus decreased from the first to the third day and increased on the fourth day of the infection period. When compared to the control without giving B. firmus, the number of V. harveyi bacteria actually increased compared to the treatment with B. firmus bacteria. Based on the results of the analysis of variance, it showed that giving B. firmus at different doses did not have a significantly different effect on the growth of V. harveyi but when compared to controls, it showed that giving B. firmus gave better results than without giving B. .firmus. Giving B. firmus bacteria with a density of 102 cfu/ml, 104 cfu/ml and 106 cfu/ml was able to reduce the number of V. harveyi compared to without B. firmus administration. cfu/ml because with a density of 102 cfu/ml it has been able to reduce the number of V. harveyi bacteria. The survival of vanname shrimp in the treatment of firmus bacteria obtained quite high results when compared to the control. giving B. firmus at a density of 106 was 87.5%, without giving B. firmus at 58.5%. Based on the results of analysis of variance on the vanname shrimp survival rate, it was found that there was no significant difference between treatments.

The purpose of this study was to determine the pattern of LAT ecdysis, especially the Freshwater Lobster of the Cherax quadricarinatus type, aged 76 days to 116 days. This research was conducted at the Experimental Station for Freshwater Aquaculture Sumber Pasir, Faculty of Fisheries and Marine Sciences, Universitas Brawijaya from July to August 2007. The method used in this study was a descriptive method in which this research gave an accurate description of an individual or group. Data collection techniques by way of direct observation. Then the data were analyzed statistically using the SPSS computer program version 11.5 for windows. Using simple linear regression analysis Crustacean growth is related to molting. In crustaceans, changes in shape and size can only occur if the hard calcareous exoskeleton is removed before the new cuticle hardens. Periodic molting or ecdysis continues by separating the old cuticle from the new instar, holding water absorption through the digestive tract, which is a characteristic of the Crustacea group as well as other aquatic insects. Then, the absorbed water is gradually replaced by biosynthesized protein, this growth process takes place continuously, the molting cycle can be divided into four stages, namely: proecdysis, ecdysis, metecdysis and intermoult.
