Abstract

High milkfish production results in high processing waste, such as fish offal which is often simply disposed of without optimal utilization. This study aims to utilize milkfish offal as a raw material for making shrimp paste with variations in salt concentration. The study used the Complete Random Design (RAL) method with three different salt treatments, namely 0% as a control, 15% and 20%. The parameters tested included proximate analysis (water, carbohydrates, proteins, fats and ash) as well as sensory tests (appearance, aroma, taste and texture). The results of the proximate test showed 0% salt concentration with a water content value of 15.37%, carbohydrate content of 34.32%, protein content of 32.21%, fat content of 15.91%, ash content of 2.18%. Salt concentration is 15% with a water content value of 14.57%, carbohydrate content of 32.54%, protein content of 26.92%, fat content of 13.46%, ash content of 12.52%. Salt concentration 20% with a water content value of 14.71%, carbohydrate content 32.34%, protein content 24.52%, fat content 13.04%, ash content 15.39%. The results of the sensory test showed 0% salt concentration with a value of 7.8, smell 7.67, taste 7.13, texture 7.53. Salt concentration 15% with appearance value of 7.93, smell 8.33, taste 8, texture 7.4. Salt concentration 20% with appearance value 7.6, smell 7.73, taste 7.4, texture 7.07. In conclusion, the water, protein and sensory content have met the requirements of SNI (water max 35%, protein min 15% and sensory min 7), the results of ANOVA statistical analysis, show that the variation in salt concentration has a real effect on the proximate and has no real effect on the sensory value.

Abstract

The total bacteria and viruses in sea worms as vannamei shrimp mother feed are greatly influenced by the ozonization treatment in worms. The purpose of this study is to determine the effect of ozonation on the number of vibrio bacteria and viruses in sea worms. This research was carried out at the CV Laboratory. Source Bangka Hatchery, Mapur Village, Riau Silip District, Bangka Regency, Bangka Belitung Province. The research method used is mixed methods with experimental testing procedures designed with a Complete Acal Design (RAL) with 4 treatments with 3 replicas each which aims to determine the effect of ozonation on the number of vibrio bacteria and viruses in sea worms. The results showed that ozonization treatment had a significant influence on the microbiological quality of sea worms, especially in terms of total Vibrio bacteria and the level of viral contamination. The ozonization treatment has been proven to be able to reduce the total number of Vibrio bacteria present in the body of sea worms. Vibrio bacteria are a group of microorganisms that are often associated with the risk of disease in humans and aquatic animals. This decrease in the number of bacteria shows that ozone can be an effective antimicrobial agent in suppressing the growth and spread of pathogenic bacteria. In addition, ozonization also affects the level of viral contamination in sea worms. Ozone is known as a powerful oxidizer that can damage the structure of proteins and nucleic acids in viruses, thereby reducing the viability and infectivity level of viruses contained in sea worm tissues. The results showed a marked difference between the control group and the ozonized treatment group, where the treatment group showed significantly lower levels of virus contamination.

Abstract

Environmentally friendly disease prevention alternatives in tiger shrimp cultivation have begun to be widely implemented, one of which is the use of microalgae, which play an important role in aquaculture activities. In addition to functioning as natural food, microalgae also have the ability to control microbiological communities in aquatic environments through various mechanisms, both by inhibiting and supporting the growth of other microorganisms. This study aims to determine the ability of the microalgae Porphyridium sp, Vulgaris sp, Phaeodactylum sp, and Nannochloropsis sp in inhibiting the growth of fluorescent Vibrio bacteria, known as one of the causes of vibriosis in shrimp cultivation. The results showed that all microalgae tested had antibacterial properties, especially the type of Nannochloropsis sp, which was able to significantly reduce the number of bacteria over a longer observation period, so it has great potential to be used as an environmentally friendly natural ingredient for the prevention of diseases caused by bacteria in shrimp cultivation.

Abstract

This study aims to determine the effect of a combination of commercial feed and maggots on protein retention in freshwater lobsters (Cherax quadricarinatus). This study was conducted in July - August 2024. The samples that have been taken were then taken to the laboratory for analysis and then ANOVA tests were carried out to determine the differences. The results of the study showed that the results of the ANOVA analysis showed a significant difference in protein levels between the treatments tested. Based on the ANOVA output, the calculated F value was 150.106 with a significance value (Sig) of 0.000, which is smaller than 0.05, so it can be concluded that there is a significant difference between the treatment groups tested. In a follow-up test using Tukey HSD, comparisons between groups showed that each treatment had a significant average difference. For example, the average difference between P0 and P1 was -1.81000, which has a significance value of 0.001, which means the difference is significant. Similarly, comparisons between P0 and P2, P0 and P3, P1 and P2, P1 and P3, and P2 and P3 all showed significant differences (p-value <0.05). Furthermore, analysis with subsets for alpha = 0.05 showed that P2 had the highest average protein content (24.2733), followed by P3 (22.9633), P1 (20.4533), and P0 (18.6433). These groups were divided into four homogeneous subsets, indicating that the P2 treatment was significantly higher compared to the other treatments. Overall, the results of the ANOVA and Tukey HSD test showed that different treatments significantly affected protein levels, with the P2 treatment showing the highest protein content.
