Abstract

Malik D, Rahmawati NO, Puspitasari O, Aprilensia D, Annisa P, Yonarta D. 2021. Application of the budikdamber system to probiotic feed in strengthening food security in the Covid-19 era. In: Herlinda S et al. (Eds), Prosiding Seminar Nasional Lahan Suboptimal ke-9 Tahun 2021, Palembang 20 Oktober 2021. pp. 476-481. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Human needs for animal protein are increasing, but the availability of fish farming land is getting narrower. Fish farming also requires feed other than land, but fish feed is getting more expensive. Steps need to be taken to reduce feed costs and creativity for alternative cultivation areas, as well as apply appropriate techniques to meet animal needs in the Covid-19 era. This paper was to develop a bucket fish farming system on probiotic feed to increase food production in the community. The writing of this scientific paper uses a qualitative descriptive method. Descriptive method is a method used to create a sequential description of the relationship between the phenomenon under investigation and the results that are not expressed in numbers. Catfish rearing in 80 L bucket media for 30 days resulted in catfish SR 41–70%, fish harvest was 2440 g (71.76 g/head), and mustard harvest produced as much as 30 bunches. However, these results are not appropriate and it is still necessary to optimize the cultivation container in order to avoid death due to predators and fish that come out of the rearing container. The catfish cultivation system can be a potential solution for fish cultivation, especially in narrow areas and aquaponic vegetable growing media such as mustard greens as additional community food in the Covid-19 era.

Abstract

The catfish cultivation business carried out by UPR Doa Mandeh since 2015 still requires support in the form of assistance and training for its development. Meanwhile, the availability of fish seeds in South Sumatra is still very dependent on other regions, such as Lampung, Jambi and West Java. The lack of use of appropriate catfish cultivation technology and the use of commercial feed has an impact on the low production of fish seeds produced. Apart from that, there has been no effort to treat waste water which has the potential to have a negative impact on the surrounding environment. For this reason, community service (PPM) is carried out, which applies lecture materials, research and publications that have been carried out by the proposing team in the form of application of biofloc technology, making liquid fertilizer and cultivating herbal plants. The aim and benefits of carrying out this activity are to develop the catfish cultivation business, increase seed production, utilize waste water from catfish rearing media into liquid fertilizer products that can be used to develop herbal plant cultivation which will ultimately increase the income of cultivators at UPR Doa Mandeh. The activity model is in the form of empowerment, development and assistance which is implemented using counseling, training and technical/production assistance methods. The results of this activity are high survival and growth rates for catfish, water quality is in the optimal range, and the richness of nutrients in wastewater from the biofloc system can be used as liquid fertilizer for herbal plants.    Keywords: biofloc; catfish; herbal plants; liquid fertilizer

Abstract

Problems often encountered in the breeding of selincah fish are that the maturation period of the male and female parent fish sometimes does not occur simultaneously. Reproductive biotechnology can be used to store sperm (sperm cryopreservation). Cryopreservation is a storage technique using a low temperature of -196oC. Extenders and cryoprotectants play an important role in the cryopreservation process. One of the extender materials that can be used is honey. This study was conducted to determine the best dose of honey as an extender material in cryopreserving selincah fish sperm. This study used a completely randomized design with four treatments and three replications. The treatments given were (P0) 100% ringer lactate solution, (P1) 0.25% honey + 99.75% ringer lactate solution, (P2) 0.5% honey + 99.50% ringer lactate solution, and (P3) 0.75% honey + 99.25% ringer lactate solution. The results of the study showed that pre-cryopreservation of selincah fish sperm included a sperm volume of 0.5 mL, sperm pH of 7, moderate sperm consistency, sperm movement duration of 120 seconds with a percentage of motility score of 5 (100%), and sperm viability of 89.50%. The post-cryopreservation study of selincah fish sperm for 14 days of storage showed the best results at P3 (0.75% honey) with a sperm motility score of 4 (90%) and sperm viability of 79.50%. Water quality data during the maintenance of selincah fish broodstock in this study were pH 6.0-7.5 and temperature 25.5 - 28.5oC.

Abstract

Eggs of dumbo catfish are known to stick to the substrate due to the presence of a mucus layer, which causes suboptimal oxygen supply and low hatching percentage. This indicates that the mucus layer must be lowered while also eliminating the need for a substrate during the hatching process. One of the natural ingredients that can be used for this purpose is papaya leaf containing the proteolytic enzyme papain. Therefore, this study aims to determine the effect of papaya leaf solution on the percentage of live embryos after soaking, hatching percentage, hatching time, survival rate, and abnormality percentage of dumbo catfish larvae. This research was carried out at the Basic Fisheries Laboratory, Aquaculture Study Program, Fisheries Department, Faculty of Agriculture, Sriwijaya University in August-October 2022. A Completely Randomized Design (CRD) was used, which consisted of four treatments and three repetitions. The treatment given was the soaking of eggs in papaya leaf solution with different concentrations of  (P0/control), 2 g/0.96 L (P1), 4 g/0.96 L (P2), and 6 g/0.96 L (P3). The results showed that P2 was the best treatment with 100% live embryos after soaking, 94.06% hatching percentage, 20.24 hours hatching time, 92.78% survival rate, and 0.93% abnormality percentage. Based on these results, the soaking of dumbo catfish eggs on papaya leaf solution could increase the hatching percentage and survival rate.
