Abstract

Daphnia magna is one of the live feeds used in aquaculture, but its availability is still limited. The population and nutritional quality of D. magna culture depend on the nutritional quality of feed where the feed source is commonly used from agricultural by-products. In contrast, pelleted feed as a source of nutrition in D. magna culture is still limited. Evaluation of commercial pelleted feeds with different protein levels and dietary protein requirements of D. magna is the focus of this research. Three treatments with different protein levels of feed with protein levels of 17.83% (P20), 32.35% (P30) and 41.98% (P40) and rice bran as control at a protein level of 8.2% (P10) with five replications for 28 days of rearing with using a completely randomized design. The average weekly population and the highest total biomass of D. magna were obtained from D. magna fed the P30 (Protein 32.35%) of 7,575 ind. tank-1. week-1 and total biomass of 290.26 g.m-3 with the feed conversion ratio of 3.85 ± 0.75 and protein efficiency ratio of 0.83 ± 0.14. The highest protein value of D. magna was obtained from D. magna fed the P30 of 3.02% ± 0.20 wet weight. The results showed that feed with a protein content of 32.35% (P30) showed the best results for cultivating D. magna. The estimated dietary protein requirement of feed for D. magna cultivation using the second polynomial regression analysis of feed protein - population and biomass is 38.8%.

Abstract

Mackarel tuna is one of the fish that is quite abundant in Banyuwangi, its existence in the Java and Bali seas is found throughout the month, therefore the use of mackerel tuna fish into processed food products is often made by the community. In addition to being a valuable product, mackerel tuna fish bones can be processed into other products that are useful in agriculture, namely organic liquid fertilizer. This study was conducted on a laboratory scale with four different treatments (length of fermentation time) including 5, 10, 15, and 20 days, where each treatment was repeated 4 times. The purpose of the study was to find out the best phosphorus and calcium content from four different treatments. The results of the study found that the best fermentation period of liquid organic fertilizer was on the 20th day of fermentation with a value of phosphorus (P) content of 0.091%, calcium (Ca) of 0.377%.

Abstract

Seasoning is widely used in many dishes for the example fried rice, meatball, chicken soup, beef stew for enhancing the flavor of food. The food will have a good taste by adding some seasoning. It will give umami taste and make people even more enjoying their meal. The purposes of this research were to know the preference level and moisture content of seasoning powder with different raw material. The analysis used in research were moisture content by gravimetric method and preference level consist of appearance, taste, aroma, texture by hedonic test. The moisture content of the anchovy, seaweed and white oyster mushroom seasoning were 10%, 20% and 15% respectively. The appearance levels were 3.7, 2.5, and 4.3. the taste level were 3.5, 1.8, and 4.5. The aroma levels were 1.9, 2.6 and 3.8. The texture levels were 2.6, 1.7 and 4.2.

Abstract

Tiger shrimp aquaculture waste still contained amount of nutrients needed by phytoplankton for its growth. Among nutrients was resulted from intensive aquaculture still can be used by phytoplankton. Phytoplankton used nitrates and phosphates for its growth and development. Phytoplankton requires nitrate concentration in 0,9-3,5 mg/ and phosphate in 0,27-5,51 mg/l. Utilization of tiger shrimp aquaculture waste for Tetraselmis sp. quality can be seen using fluorescence microscope with the cell of Tetraselmis sp. had to stained by acridine orange before observed using fluorescence microscope. The concept of this staining when cells of Tetraselmis sp. radiated green colour showed that cells was alive whereas cells radiated orange colour showed that cells was dead or damaged. This matter caused living cells could reducted acridine orange pigment enzymatically until become green radiated cells, instead damaged cells showed orange colour. Research procedures included cultivating Tetraselmis sp. in various dosages waste of tiger shrimp aquaculture as fertilizer. This various dosages are 2 g/l, 4 g/l, 6 g/l and 8 g/l. Culture media for Tetraselmis sp. was saltwater. Sterile saltwater was put into jars about 1 L and later added wastewater to jars. Reading of protein expression helped using imageJ software that showed histogram graphics accompanied by mean. Mean resulted by graphics indicated protein could be expressed. Based on expression of fluorescence protein with 2 g/l wastewater dosage showed that amount of protein could be ecpressed was higher than other wastewater dosage by mean value from ImageJ.

Abstract

The research that has been done aims to analyze the effect of the work environment and employee competence on employee performance at a seafood processing company in Probolinggo City, East Java. Based on the results of the analysis of the calculation of the first hypothesis (H1), which states that the work environment has a positive and significant effect on employee performance, the t-count value of 19,845 is greater than the t-table value, which is 1,677 and the significance value obtained is less than 0.05, which means that the work environment has a positive and significant effect on employee performance, the results of the calculation analysis of the second hypothesis (H2) which states that employee competence has a positive and significant effect on employee performance obtained a t-count value of 14,471 greater than the t-table value of 1,677 and the value the significance obtained is less than 0.05, which means that employee competence has a positive and significant effect on employee performance, while the R-square value obtained is 0.897 which states that work environment variables and employee competency affect employee performance by 89.70% and the remaining 10.30% influenced by other variables.

Abstract

Process capability in processing fishery products is a future challenge for the fishing industry, one of which is katsuobushi. The capability process refers to how a company can produce according to specifications to make it effective and efficient. The absence of process capability in the company is the basis for stating an effective and efficient process. The proposed study is to determine the company's current condition and provide suggestions for process improvement and evaluation. Through assumptions, this study influences the results of Cp and Cpk, which are calculated by Minitab software version 21st  as a method for measuring performance by identifying broad process tolerance production. In this study, the results for each data generated met data accuracy and standards. Still, at smoking 3rd and 4th stages, it was necessary to review specification values because of the value of Cpk < 1.00. As a result, after improving the standard by the six sigma concept, Cpk values are obtained > 1.00.

Abstract

Shrimps are commodities that prone to deteriorate at room temperature. Good application on cold chain system is expected to inhibit the growth of bacteria that cause deterioration in the quality due to the unavailability of a suitable environment for bacterial activity. Tthis study aimed to determine the processing characteristics of peeled deveined tail on (PDTO) cooked peel Litopenaeus vannamei shrimp, and to identify the effectiveness of cold chain application on microbiological, organoleptic, and sensory quality at PT. XYZ, East Java, by a quantitative descriptive method with an observational approach. The results showed that the processing of PDTO Cooked Peel vannamei shrimp at PT. XYZ, East Java includes raw materials receiving, weighing I, washing I, cutting heads (de heading), washing II with a shrimp washing machine, size separation, cutting, washing III, soaking, cooking preparation, weighing II, cooking, cooling, peeling, washing IV, freezing, machine glazzing, hardening, weighing, packaging in poly bags and sealing, final checking, metal detecting I, packing in cartons, storage in cold storage, metal detecting II and loading. The cold chain of shrimp processing is applied on room, water, and shrimp raw materials effectively assessed from the results of standardized microbial, organoleptic, and sensory tests
