Abstract

Biofloc technique is a cultivation method that utilizes microorganisms, especially heterotrophic bacteria, to convert toxic inorganic nitrogen waste, such as ammonia, into biomass that is beneficial for fish. In the biofloc system, heterotrophic bacteria play an important role in the formation of flocs, which are aggregates of microorganisms and organic particles that function as additional food sources for fish. These bacteria use nitrogen from ammonia in water to produce biomass, which can then be eaten by fish. This study aims to examine the effect of a combination of commercial probiotics and herbal ingredients on the growth of tilapia (Oreochromis niloticus). The method used in this study was an experiment with a Completely Randomized Design (CRD) consisting of four treatments and three replications. The treatments tested included treatment A (control), treatment B (EM4 + Ginger), treatment C (EM4 + Kencur), and treatment D (EM4 + Turmeric). This study was conducted for 35 days at the Moncongloe Maros Aquaculture Institute, with test fish in the form of tilapia seeds measuring 5-7 cm and aged 1 month. The results showed that the combination of commercial probiotics and herbal ingredients in treatment C (Probiotic EM4 + Kencur) produced the highest floc volume of 20.17 mL, while treatment D (EM4 + Turmeric) produced the lowest floc volume of 12.04 mL. Treatment C also recorded the highest Specific Growth Rate (SGR), which was 2.90%, while treatment D recorded the lowest SGR of 2.41%. Kencur is considered to have a positive effect because of its essential oil content which functions as a sedative effect, helps fish physiology, increases growth, maximizes protein digestibility, and increases feed efficiency. Anova analysis showed that SGR had a significant effect (P<0.05), while absolute length growth and survival rate did not show significant differences between treatments (P>0.05).

Abstract

Vibrio harveyi bacteria are one of the main causes of mass mortality in shrimp in a short time. Chaya (Cnidoscolus aconitifolius) is a common plant that grows in many places in Central America, the Yucatan Peninsula of Mexico and has been widely cultivated in tropical and subtropical areas. The purpose of this study was to analyze the content of secondary metabolites in chaya leaves as antibacterials against Vibrio harveyi and to analyze the amount of inhibition of chaya leaves against Vibrio harveyi bacteria. The method used in this study was experimental with 4 treatments with 3 replications each, namely A (500 µg/mL chaya leaf extract) B (1000 µg/mL chaya leaf extract) C (Oxytetracycline antibiotic) and D (96% ethanol). The study was conducted from June to July 2024 at the Laboratory of Parasites and Fish Diseases, Faculty of Marine Sciences and Fisheries, Hasanuddin University. The results showed that the activity of chaya leaf extract (Cnidoscolus aconitifolius) did not show inhibition against V. harveyi bacteria at concentrations of 500 and 1000 µg/mL. Likewise, 96% ethanol did not show inhibition against V. harveyi bacteria. The inhibitory activity of Oxytetracyclin showed inhibitory activity with an average inhibition size of 9.26 mm. This is thought to be due to the low sensitivity of chaya leaf extract to V. harveyi bacteria. V. harveyi is known as a bacteria with a high level of malignancy when infecting, so it is thought to require a substance with stronger inhibitory activity.

Abstract

This Community Service (PKM) activity was funded by the Directorate General of Research, Technology, and Community Service in the 2024 budget year with contract number 1069/LL9/PK.00.PPM.BATCH.2. This activity took place in Mandalle Village, Pangkep Regency with the title Integrated Farming LETSGO (Integrated Catfish, Vegetables and Maggots) with the partner Turicinnai II Fish Cultivation Group. The problem experienced by the partner was that the pond they had had not been producing for a long time due to the high cost of manufactured feed and the low selling value of catfish. Through the PKM activity carried out by the team from the Balik Diwa Maritime Technology and Business Institute and STIE YPUP Makassar, they succeeded in overcoming the PKM partner's problem by creating 6 (six) complete aquaponic ponds (vegetables and fish), 1 maggot cultivation installation and providing training on maggot cultivation, aquaponic vegetable sowing, and food product sales training. The results of this PKM activity are expected to be able to increase the productivity and profits of PKM partners and increase the benefits of this activity for the surrounding community. The pre-test results showed that the level of knowledge and skills about aquaponics and maggots were generally in the poor category. However, after the learning activities, the post-test results showed that the level of knowledge and skills increased significantly and were generally in the good category. In general, partners considered that aquaponics and maggot maintenance activities were technically easy to apply, economically inexpensive, and ecologically could reduce waste, especially organic waste.

Abstract

Kappaphycus alvarezii seaweed produces carrageenan; its growth and development are highly dependent on the quality of the waters and nutrients such as nitrate, phosphate, and potassium. The planting method that cultivators often carry out is to take it directly from the seaweed that is being harvested. This pattern makes the growth of seaweed less than optimal. One solution is to fertilize. One type of fertilizer that can be used is natural fertilizer, such as kasgot fertilizer. This study aims to determine the combination of soaking time and concentration of kasgot fertilizer that effectively increases the growth and carrageenan content of Kappaphycus alvarezii. This research method uses the treatment of the duration of kasgot fertilizer immersion for 2 hours, 4 hours, 6 hours and without immersion (control) and the concentration of kasgot fertilizer of 2 grams, 4 grams, 6 grams, and without kasgot fertilizer (control), repeated 3 times. The results show that the kasgot fertilizer immersion treatment can increase weight, growth rate, and carrageenan value. The higher the dose given, the higher the weight, growth rate, and carrageenan value, although in statistical tests, it was found that the immersion treatment did not significantly affect weight or growth rate. Water quality during the study (temperature, salinity, pH, and depth) was still within the standards for cultivating K. alvarezii seaweed. Further research is needed on using kasgot fertilizer in cultivating other types of seaweed or using different doses.

Abstract

This study aims to assess the impact of skipjack tuna (Katsuwonus pelamis) offal soaking water on the mass culture of Daphnia sp. for the growth of Betta fish (Betta sp.). This study was conducted for 30 days with treatment of offal 4.5 ml/L (treatment B), 7.5 ml/L (treatment C), 10.5 ml/L (treatment D) and commercial feed without skipjack offal soaking water as control (treatment A). The variables data of this study consisted of growth rate and population density of Daphnia sp., which were analyzed using variance analysis. The results showed that the highest population growth rate was found in the treatment of offal soaking water 4.5 ml/L with a value of 11.59% and a density of 260 individuals/liter on the 19th day of rearing. Daphnia sp. produced from soaking tuna offal can also be used as a natural food for the growth and development of Betta fish, although its effectiveness is still lower than other organic materials. Keywords: Daphnia sp., growth, mass culture, skipjack offal ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh air rendaman jeroan ikan cakalang (Katsuwonus pelamis) pada kultur massal Daphnia sp. terhadap pertumbuhan ikan Betta (Betta sp.). Penelitian ini dilakukan selama 30 hari dengan perlakuan air rendaman jeroan ikan cakalang sebanyak 4,5 ml/L (perlakuan B), 7,5 ml/L (perlakuan C), 10,5 ml/L (perlakuan D) dan pakan komersil tanpa air rendaman jeroan ikan cakalang sebagai kontrol (perlakuan A). Data variabel penelitian terdiri dari laju pertumbuhan dan kepadatan populasi Daphnia sp. dianalisis menggunakan analisis ragam. Hasil penelitian menunjukkan bahwa laju pertumbuhan populasi tertinggi pada perlakuan menggunakan air rendaman jeroan 4,5 ml/L dengan nilai 11,59% dan dengan kepadatan individu 260 individu/liter pada hari pemeliharaan ke 19. Daphnia sp. yang dihasilkan dari perendaman jeroan ikan cakalang juga dapat digunakan sebagai pakan alami untuk pertumbuhan dan perkembangan ikan Betta (Betta sp.) walaupun efektivitasnya masih lebih rendah dibandingkan bahan organik lainnya.
