Combination of Ara (Ficus racemosa) and Singkong Leaf (Manihot utillisima) in Cat Fish (Pangasius hypophthalmus)

One of the problem cultuvation of catfish in the North of Kalimantan is the cost of commercial fish feed in the market is relative expensive. The alternative that can be effort is make feeds by homemade with utilizing local ingredients from nature that is no economi value like fig fruit (F. racemosa) and cassava leaves (M. utillisima) the plants are commonly found in Malinau District. The purpose of the research is to find out the growth of catfish seeds (P. hypophthalmus) by using a combination of  fig fruit (F. racemosa) and cassava leaves (M. utillisima). This research using experimental method, completely randomized design with four treatments and three replications. The data obtained were processed using Analysis of Variance (ANOVA) and continued with  test  least significant difference. The best absolute weight growth of catfish (P. hypophthalmus) at  the treatment D was (1.21 grams), the best absolute length growth at treatment D was (1.09 cm), the best specific growth at the thirty five (0,013%), the best Feed Covertion Ratio for treatment D was (2.11%) and the best Survival Rate for treatment D was (96.67), while the water quality in ammonia on the threatment A was not better than the optimal value 1 mg / L. Combined feed in treatment C is the best treatment compared to treatments A and B, but the combination feed is still unable to produce better growth when compared to treatment D (Commercial)

IN VITRO ANTIBACTERIAL EFFICACY OF LEAVES EXTRACT OF Centela asiatica AGAINST Vibrio harveyi AND Aeromonas hydrophila

Disease infection is one of the limiting factors that affect productivity in aquaculture and has caused economic losses. Luminescent vibrios and motile aeromonas septicemia (MAS) are diseases caused by Vibrio harveyi and Aeromonas hydrophila bacteria, respectively. Certain plants have antimicrobial compounds and can potentially be used to treat the diseases, such as Centella asiatica. In the present study, the crude leaves extracts of C. asiatica were examined for its antibacterial potential using methanol solvents against V. harveyi and A. hydrophila bacteria. Different concentrations of 50 mg/mL and 100 mg/mL were checked for its antibacterial activity. The crude extract was also tested for phytochemistry content and LC50 using Brine Shrimp Lethal Assay. The crude extracts of C. asiatica showed a remarkable antibacterial activity with inhibition zone of 10.57 mm against A. hydrophila and 21.14 mm against V. harveyi. The phytochemistry test result showed that C. asiatica leaves contain alkaloid, phenol, and tannin compounds. The acute lethal concentration (LC50) of C. asiatica after 24 hours exposure to the extract mixture was 254 mg/L. The results confirmed the potential use of C. asiatica extracts as a source of antibacterial compounds

Pengenalan Budi Daya Ikan dalam Ember untuk Kemandirian Pangan di Kampung Enam, Kota Tarakan

The Covid-19 pandemic has had a major impact on society, such as job losses, rising staples, and economic hardship. Prices of food needs that continue to increase and are not affordable have resulted in food problems, one of which is protein. One of the high-quality protein is protein from fish. Fish as a fishery commodity that is relatively easy to cultivate on a large industrial scale and household scale for food self-sufficiency is catfish (Clarias sp). The purpose of this activity is to add insight and knowledge of the community about budikdamber for food self-sufficiency. The method of implementing community service activities in Kampung Six is carried out by counseling and training methods on Budikdamber. In this training activity, a bucket with 40 liters of water and 20 catfish seeds was used. Maintenance was carried out for 60 days with ad satiation feeding three times a day. Observations were made on growth, survival and water quality. The results of the activity found that 93% of the community partners had understood about Budikdamber. Budikdamber maintenance by partner communities gets an absolute weight growth value of catfish of 14 g, catfish survival value of 75%, and 1 bunch of kale per bucket. Based on the results of this activity, it is hoped that there will be the provision of special land for Budikdamber as an example for people who want to develop in their respective yards.The Covid-19 pandemic has had a major impact on society, such as job losses, rising staples, and economic hardship.

Benefits of Tiwai Onion (Eleutherine Americana) Extract as Phytopharmaceutical Plant to Inhibit the Growth of Vibrio Harveyi Through In-Vitro and In-Vivo

HighlightsEleutherine americana was a plant that was known to contain antibacterial alkaloids, steroids, phenolics, and flavonoidsEleutherine americana extract was able to inhibit the development of V. harveyi both through in vitro and in vivo tests on tiger shrimp (Penaeus monodon).The use of vibriosis antibiotics in tiger shrimp was often not controlled so the results obtained were not effective AbstractThe use of vibriosis antibiotics in tiger shrimp was often not controlled, so the results obtained were not effective. The addition of antibiotics would cause resistance to V. harveyi. Eleutherine americana is a plant that is known to contain antibacterial alkaloids, steroids, phenols, and flavonoids. This study aimed to determine the effectiveness of inhibitory effects of E. americana extract against V. harveyi through in-vitro and in-vivo tests on tiger shrimp larvae. In-vitro testing consisted of 7 treatments and 3 replications, namely treatments A (0.1%), B (0.2%), C (0.3%), D (0.4%), E (0, 5%), F ethanol 70% (K-), and G chloramphenicol 0.01% (K +) treatment. The largest inhibition zone diameter of E. americana extract was shown in treatment C (0.3%), with an average value of the inhibition zone produced of 7.5 mm. Challenge test with V. harveyi concentration of 107 CFU / ml in the in-vivo test consisted of 5 treatments and four replications namely; A treatment without E. americana extract, B extract 6 ppm, C extract 12 ppm, D extract 18 ppm, and treatment E without extract and V. harveyi. The results of the challenge test with V. harveyi bacteria were significantly different in control (chloramphenicol 0.01%), where the highest survival rate was in the treatment of 12 ppm extract (43.34%). E. americana extract could inhibit the development of V. harveyi bacteria both through in-vitro and in-vivo tests on tiger shrimp (Penaeus monodon)
