Abstract

The active ingredients contained in seaweed prepare for pharmaceutical, cosmetic and food supplement needs from seaweed Sargassum sp. and Ulva sp. in different seasonal conditions it is thought to have a contribution of specific active ingredients. However, the fatty acid profile and morphology of the seaweed species Sargassum sp. obtained in the dry season and rainy season had the same results as the profile of the seaweed Ulva sp. which was collected in the Bangsring Beach area, Wongsorejo District, Banyuwangi, Indonesia. This is thought to be due to the extreme differences in dry season and rainy season conditions that have not yet resulted in real or drastic changes in the composition and quantity of macro and micronutrients, water quality and active fatty acid compounds as well as the adaptability of seaweed. Fatty acids of Sargassum sp. dominated by the composition of linoleic acid (C18:2), palmitic acid (C16:0) and oleic acid (C18:1), while the fatty acids of Ulva sp. dominated by the composition of heptadecanoic acid (C17:0), pentadecanoic acid (C15:0) and linoleic acid (C18:2n6).

Abstract

Plankton plays an important role in shrimp cultivation in ponds, both as an indicator of water quality and as a natural food source for shrimp that are raised. The purpose of this study was to measure the relationship between the dynamics of the plankton community, the concentration of total organic matter, and water salinity with the abundance of plankton in intensive shrimp farming systems. The study was conducted on six units of ponds located in Cirebon district, West Java, Indonesia. The ponds were lined with HDPE on each side and plastic mulch at the bottom. Post larvae of shrimp were stocked at an average density of 110 shrimp.m-2 and maintained for 98 days. Water quality samples were collected for daily measurement. Data were analyzed descriptively and then analyzed using Pearson's correlation test and regression. The results of this study showed that during the shrimp rearing period, 65 species of plankton were identified, consisting of Chlorophyta 20%, Cyanophyta 15.38%, Diatoms 26.15%, Euglenophyta 6.15%, Dinoflagellates 4.62%, Protozoa 10.77%, and Ciliates 16.92% with an average density ranging from 7.56x105-19.99x105 cells.mL-1. Chlorella sp. (Chlorophyta) and Oscillatoria sp. (Cyanophyta) were found to be the dominating species in all ponds. Total phytoplankton density tended to be higher during the first 54 days of culture. The results of the correlation and regression tests showed that the composition of plankton, the concentration of total organic matter, and the salinity of the water affected the abundance of plankton in the pond.

Abstract

The demand for common carp in Indonesia is high, and the success of seed production relies on the quality of the broodstock. However, freshwater aquaculture faces challenges from diseases, particularly parasites like Argulus japonicus. This study aimed to determine the prevalence, intensity, and degree of infestation of A. japonicus on common carp. The research method was survey. The research was conducted in October 2019 at Ngawi Fish Hatchery Center and in November 2023 at Tambakrejo Village, Waru, Sidoarjo, East Java, Indonesia. There were 26 broodstock of common carp as samples. A. japonicus were ectoparasites found to infest 10 common carp (Cyprinus carpio) broodstock that were ready to spawn at Fish Hatchery Center in Ngawi, East Java and 16 common carp (C. carpio) that raised from Tambakrejo Village farmer in Waru, Sidoarjo, East Java. Prevalence of the fish infested with A. japonicus was same in 100% at both regions. However, there is different in the intensity of A. japonicus at Ngawi Fish Hatchery Center (29 individuals/head) and at Tambakrejo Village, Waru, Sidoarjo (42,5 individuals/head). But, the degree of infestation in both location was classified as severe. Attachment site of A. japonicus were in the fish body surface, fins, and mouth. During the research, water quality is in normal limits that can be observed by 28°C temperature, 7.1 pH, and 2.6 mg/L DO. In conclusion, common carp in Ngawi Fish Hatchery Center and Tambakrejo Village, Waru, Sidoarjo, East Java, were infested with the heavy category of A. japonicus.

Abstract

One of the organic fertilizers that has the potential to cultivate Chlorella sp. is the cow's rumen. To increase the nutrient content in the cow's rumen, the cow's rumen must be made into bokashi and enriched with chicken manure. This study aimed to determine the use of cow's rumen bokashi enriched with chicken manure at different doses on Chlorella sp cell density. The research design used was a Completely Randomized Design (CRD) with 5 treatments and 3 replications, namely P0 (2 g/L cow's rumen bokashi), P1 = 2 g/L cow's rumen bokashi enriched with 2.5 g/L chicken manure, P2 = 2 g/L cow's rumen bokashi enriched with 3.0 g/L chicken manure, P3 = 2 g/L cow's rumen bokashi enriched with 3.5 g/L chicken manure, and P4 = 2 g/L cow's rumen bokashi enriched with 4.0 g/L chicken manure. The results showed that the highest cell density of Chlorella sp. occurred in treatment P3 (i.e. 456.1 ± 15.1 í— 104 cells/mL) and the highest specific growth rate occurred in treatment P0 (i.e. 0.20 ± 0.0/day). Nutrient levels in the culture medium are optimal for Chlorella sp., with nitrate ranging from 0.1375 to 0.2833 mg/L and phosphate ranging from 2.4889 to 2.8650 mg/L. From the results of this study, it can be concluded that the use of cow's rumen bokashi enriched with chicken manure had a very significant effect on cell density and specific growth rate of Chlorella sp. (P<0.01).

Abstract

One alternative approach to facilitate the utilization of feed by tilapia is the addition of probiotic in feed. In this study, we compare the effects of commercial probiotic EM4 and homemade probiotics on tilapia growth. This research was conducted in PT. Sahaja Berkah Abadi at wonosalam, jawatimur, indonesia. The study was designed as a completely randomized design with 3 treatments and 4 replications, encompassing control group (C), commercial probiotics (G1), and homemade probiotic (G2). The commercial probiotics (G1) contained Rhodopseudomonas sp., Lactobacillus sp., Streptomyces sp., and Actinomycetes sp. while the homemade probiotic (G2) contained starter bacteria Lactobacillus casei and herbal plant such as ginger, curcuma, and tumeric. Parameters observed during the study included weight gain (WG), specific growth rate (SGR), and survival rate (SR). The results revealed that both G1 and G2 performed better than the control group. The weight gain for the control, G1, and G2 groups were 2.38±0.03 g, 3.09± 0.01 g, and 3.13 ± 0.03 g, respectively. Similarly, the specific growth rates for the control, G1, and G2 groups were 4.25±0.03%, 5.52± 0.02%, and 5.59 ± 0.03%, respectively, while the survival rate remained at 100% across all groups. The water quality in all treatments during maintenance met the standard requirements for tilapia, with temperatures ranging from 25.5 to 26.7 °C and pH levels between 6.7 and 6.9. These findings suggest that the probiotics incorporated in G2 present a cost-effective alternative to those in G1, offering a promising option for tilapia cultivation.

Abstract

Aquaponics is a closed recirculating aquaculture method combined with hydroponics. This method is very alternative for raising fish while growing plants in specially designed media. The mechanism obtained is very effective and efficient, plants can utilize fish waste as nutrients for plant growth. Poisonous fish waste in ponds can be reduced by plants as nutrients for organic substances. This can enhance profitable bio-integrated food production systems. Plants will serve as vegetation filters. This study aimed to determine the effectiveness of aquaponic treatment in high-salinity water by observing the growth in three species of seaweed namely Gracilaria sp., Sargassum sp., and Kappaphycus alvarezii. The research design used the LSD method and was carried out for 63 days. Data analysis using Analysis of Variance (ANOVA) then continued with the test Duncan's Multiple Range Test. The research method involved making aquaponic media including preparing containers for seaweed cultivation and fish and shrimp farming, observing seaweed growth rates, and measuring water quality. Aquaponic treatment can increase the growth rate of intensively cultivated seaweed. The results showed the best weight growth rate in the aquaponic treatment of Gracilaria sp. with a value of 12.33 grams than Kappaphycus alvarezii 11.33 grams and Sargassum sp. 10.83 grams.

Abstract

Kampung Dolly was originally the largest prostitution areain Southeast Asia which is associated with nightlife. On 19June 2014, a policy was issued by the Surabaya city govern-ment to close this prostitution area which abruptly causedmany people to lose their jobs that previously could obtain anoverall economic turnaround of over 300 million rupiah pernight. Even after a decade, the community still has not beenable to recover its economic independence. The research wasdeemed indispensable for assisting the community regain itseconomic strength. This activity was conducted by the lectur-ers and students of the Faculty of Fisheries and Marine Uni-versitas Airlangga to foster a creative economy in KampungDolly community by utilizing fishery resources for 41 partici-pants who were members of MSME N'Jarang Nambe, Kam-pung Dolly, Surabaya. Assistance and monitoring were alsoprovided to ensure a successful outcome for the participants.Preliminary questionnaires found that 87.8% of participantshad ever bought fisheries products and were knowledgeableabout various diversification product types available in themarket. The final questionnaires observed the participants'preferences on product packaging, marketing, and licensing oftheir products. A total of 54% of participants preferred simplepackaging with affordable pricing, 66% of participants wouldrather sell their product at conventional markets directly, andonly 37% of participants have applied for business permits. Inconclusion, this activity has successfully providedcomprehensive insight regarding the introduction of productdiversification and assistance during the production process totrigger the entrepreneurial spirit for regaining economicstability in Kampung Dolly communities.

Abstract

The oxygen consumed is used to oxidize food substances to produce energy. Therefore, the metabolic rate is usually indicated by the rate of oxygen consumption per time unit. In most intensive aquaculture systems, oxygen content is widely used due to the high stocking density and maximum feeding rates. This study aimed to evaluate the growth performance of freshwater pomfret (Colossoma macropomum) treated with increased oxygen in two different systems. The study was conducted in a laboratory scale by applying T-test data analysis. The difference of treatment level applied in the comparison of aeration and microbubble consists of two treatments and three replications. The researcher used commercial floating pellets PF0 with 25% protein content, the feeding rate was 5% of the biomass. The feed was given daily during the culture for two times a day. Data of the study were analyzed using T-test on the Statistical Product and Service Solutions (SPSS) software Version 17.0. Results of the study showed that aeration system using microbubble resulted in dissolved oxygen (DO) of 6.5 ± 0.17, 100% pomfret fish survival rate (SR), Survival Growth Rate (SGR) of 1.83 ± 0.24, Feed Conversion Ratio (FCR) of 1.37 ± 0.17, Protein Efficiency Ratio (PER) of 2.79 ± 0.37, Feed Utilization Efficiency (FUE) of 0.67 ± 0.09, Absolute Weight Growth of 52.02 ± 1.60; it was better than using aeration. This study has developed a model of freshwater pomfret fish aquaculture to provide growth value.
