Abstract

West Nusa Tenggara Province has potential seaweed resources. This study aims to analyze the yield of carrageenan at different cultivation ages. West nusa tenggara province has an area for seaweed cultivation of 25,206.6 ha. The area is spread over the districts of East Lombok, west Lombok, central Lombok, Sumbawa, Dompu, Bima, the city of Mataram, the city of Bima, west Sumbawa and north Lombok. Seaweed is a chlorophyll plant and is classified as a low-level plant that has no true roots, stems or leaves, but only resembles a stem called a thalus. This research was conducted in Ekas Bay, Ekas Buana Village, Jerowaru District, East Lombok, and West Nusa Tenggara. This study used a completely randomized design (CRD) with 4 treatments: P1: 15 days, P2: 25 days, P3: 35 days, and P4: 45 days. The yield of K. alvarezii carrageenan obtained the highest score in treatment (P4), which was 53.4%. The chlorophyll content of K. alvarezii seaweed obtained the highest value in treatment (P4), namely 5.1 mg/L. Based on the results of research data analysis, it was found that the different cultivation ages of Kappaphycus alvarezii had a significant effect on absolute growth, specific growth and no significant effect on carrageenan content. In this study, the P4 treatment (45 days) obtained an absolute growth of 149 g, a specific growth of 5.46%, and a carrageenan content of 53.4%, and the best chlorophyll content value was 5.1 mg/L. The conclusion of this study is the best maintenance in this study, namely treatment P4 (45 days) obtained absolute growth of 149 grams, specific growth of 5.46%, and carrageenan content of 53.4%, and the best value of chlorophyll content is 5.1 mg /l.

Abstract

Silkworms, as natural food, have an essential role because they can stimulate fish growth. However, silkworms in nature are not always available all year round, so it is necessary to cultivate silkworms. Silkworms need a medium containing organic matter and inorganic matter for their growth. Catfish farming wastewater contains a lot of organic matter. This study aims to evaluate the effect of catfish farming waste (Clarias sp.) on the growth of silkworms (Tubifex sp.) in different initial biomasses. This research method uses the experimental method Complete Randomized Design with four treatments and three repeats. The treatment used is P1 = 15 grams of silkworms; P2 = 20 grams of silkworms; P3 = 25 grams of silkworms; and P4 = 30 grams of silkworms. For analyzing data use ANOVA with a 95% confidence level and the Lower Significance Difference test on SPSS. The results showed that the provision of catfish farming waste had a real influence on the growth of silkworms. Silkworms' absolute weight and biomass were highest in treatment four, which were 195.33 g and 0.112 g. Therefore, catfish farming waste has the potential to be used as raw material for silkworm feed.

Abstract

The need for tilapia fish supplies for the world market is not yet fully met, so the implementation of intensive cultivation is expected to increase aquaculture production results. Recirculation systems are an option for controlling the quality of cultivation water, and the addition of UV lights is expected to be able to kill bacteria found in cultivation waters. This research aims to evaluate the use of UV lamps in fish nurseries and analyze the best use of UV lamps in tilapia nurseries. This research was carried out for 45 days, at the Fish Production and Reproduction Laboratory, Mataram University using an experimental method with a completely randomized design (RAL) consisting of 4 treatments and 3 replications, namely P1: without UV lamp, P2: 5 Watt, P3: 10 Watts, and P4: 15 Watts. Test parameters include absolute length growth rate, specific length, absolute weight, specific weight, Feed Conversion Ratio (FCR), Survival Rate (SR), water quality and bacterial abundance. Data were analyzed using Analysis of Variance (ANOVA) and continued with the Duncan test. The results showed that the best growth rate parameters, Feed Conversion Ratio (FCR), Survival Rate (SR) and bacterial abundance were found in P4 with an absolute length growth rate of 6.4cm, specific length of 0.05%/day, absolute weight growth of 9.7gr, specific weight of 0.06%/day, Feed Conversion Ratio (FCR) value of 0.7, Survival Rate (SR) of 94% and bacterial abundance of 5.7 x 105 CFU/ml.

Abstract

This study investigates the abundance and diversity of bacteria associated with two intertidal seaweeds, Sargassum sp. and Kappaphycus alvarezii, in Ekas Bay. Intertidal zones are dynamic environments where seaweeds and their associated microbial communities play crucial roles in ecological processes. Seaweeds host a variety of bacteria that contribute to nutrient cycling, seaweed health, and overall ecosystem function. The primary variable measured in this study was the bacterial abundance, expressed as Colony Forming Units per milliliter (CFU/mL). The conclusion of these findings has positive implications for the environmental health around the floating raft, base stakes, Sargassum sp. and Kappaphycus alverazii. The absence of harmful bacteria supports the sustainability of aquatic ecosystems and can provide positive benefits for the species inhabiting those areas.

Abstract

Siamese fighting fish (Betta splendens) is one of the fisheries commodities in great demand because it has an attractive physique and relatively high economic value. The increasing market demand for male Betta means a method is needed to produce male offspring en masse. This research aimed to determine the effect of bitter melon (Momordica charantia) solution on the male sex ratio of Betta by immersion of larvae in different concentrations. This research used an experimental method with a completely randomized design (CRD), which included four treatments with three replications, namely control treatment, P2 treatment with a concentration of 1.5 ml/l, P3 treatment with a concentration of 3 ml/l, and P4 treatment with a concentration of 6 ml/l. The data obtained was analyzed using the ANOVA method. If the data analysis showed a significant effect, it was carried out using Duncan's advanced test. The research showed that the treatment applied had a real influence on the percentage of male Betta but did not significantly affect the survival rate. The highest sex percentage value for Betta was found in treatment P4 (6 ml/l), which was 77%.

Abstract

This study examined the effects of dietary supplementation with Eichhornia crassipes leaf extract on the growth performance and hematological parameters of common carp (Cyprinus carpio). Phytochemical screening confirmed the presence of bioactive compounds such as flavonoids, alkaloids, and saponins, with moderate antioxidant activity (50.89% DPPH inhibition). Experimental treatments showed that fish receiving moderate levels of the extract had significantly higher erythrocyte and leukocyte counts, indicating improved oxygen transport and immune function. Additionally, the group with the highest absolute weight gain suggests better nutrient absorption. All treatments maintained a 100% survival rate and stable water quality, confirming the extract’s safety and environmental compatibility. These results support the use of E. crassipes as a sustainable, cost-effective, and environmentally friendly alternative to synthetic growth promoters in aquaculture. Further research is recommended to investigate its long-term effects and mechanisms of action.
