Abstract

The purpose of the research was to evaluate the response of the population abundance of Moina macrocopa to the addition of Spirulina platensis flour into mass culture media. In this research, each added 0 mg/day (control), 500 mg/day, 750 mg/day of  Spirulina platensis, as well as the treatments being tested. As a control, dry manure was used. This research was conducted at the Wet Laboratory (wet lab.) Faculty of Fisheries and Marine, Lambung Mangkurat University Banjarbaru. As an experimental container (experimental unit) were 12 aquariums measuring 45 x 25 x 30 cm. In this research, an experimental design was applied, namely Completely Randomized Design (CRD). Statistical testing using Test F or ANOVA with a significant level of 5% and 1%. The further statistical analysis used for the significant treatment calculated F value was Duncan's Test (DMRT). The results showed that at the peak of the abundance of Moina macrocopa (day 21), the highest population was in treatment B = 708 ind/liter, followed by treatment C=535.33 ind and treatment A=70.66 ind/liter. The results of statistical tests (ANOVA) showed that there was no significant difference (F < Ftable 0.05) in the abundance of Moina macrocopa in the three mass culture media added with Spirulina platensis flour.

Abstract

Abstract. Research and development of biofloc aquaculture system until now only in the range of 14-15 species conducted. Even though this technology is able to increase production several times compared to conventional systems, so it is necessary to diversify species that allow development, especially economically important fish. There are 4 species of fish that are feasible to be developed, especially freshwater fish groups in wetlands, such as fish (climbing perch; Anabas testudineus Bloch, snakehead, Channa striata Bloch, giant gouramy , Opronemus gouramy and Pangas , Pangasius hypophthalmus. This research has been carried out in the range of June 2023- February 2024 using a complete randomised complete block design, 4 treatments climbing perch; snakehead, giant gouramy and pangas with 4 replicates. Stocking density of 1000 fish 2500 L-1 using 2 m diameter round pond with biofloc media; feeding twice a day and the amount of feed given was 2.5% of total weight, for 158 days. Research parameters included; daily growth rate (%/day), feed efficiency. FCR, weight gain (gr) and length gain (cm), water quality and biofloc content (ml/L). The results showed that the results of the anova test showed a significance value (Sig.) of 0.000 0.05, so there was a significant difference between treatments of the daily growth rate (SGR) parameter, the results of the area test also showed differences between treatments. The highest daily growth rate was obtained in climbing perch, followed by pangas, giant gouramy and Snakehead. The results of the anova test for weight gain showed a significance value (Sig.) of 0.000 0.05, so there was a significant difference between treatments. The anova test results showed a significance value (Sig.) of 0.052 0.005, so there was no significant difference between treatments; the growth of each treatment showed peculiarities between species depending on genes. Anova test results show that the feed conversion of fish research significance value 0.000 0.05 means that the four types of fish studied, significantly different from those reared in the biofloc system Survival rate of fish research significance value 0.000 0.05 means that the four types of fish studied, significantly different from those reared in the biofloc system. Water quality with 4 main parameters is able to support the growth and development of the 4 economically important fish species studied.

Abstract

Chlorella sp is a type of natural feed that is given to the fish larvae. Chlorella sp. culture requires fertilizer that serves as a food source to stimulate its growth. Fertilization for Chlorela culture media can utilize bean sprout waste because it is rich in element of N and enriched with the addition of eco enzymes. Eco enzyme is the result of fermentation of organic waste such as fruit waste, sugar and water which produces enzymes that help in the process of accelerating the overhaul of organic matter. This study aims to analyze the growth of chlorella with the addition of eco enzyme to the culture media of bean sprout waste extract. The research was carried out by an experimental method using a Complete Random Design with 4 treatments and 3 replicates, namely Chlorella sp. culture on bean sprout waste extract media with the addition of eco enzyme as much as 0.5,10,15 mL per liter for 15 days. The results showed that the treatment of bean sprout waste extract culture media with the addition of eco enzyme as much as 10 mL/L. gave the population of Chlorella sp. the highest was 106.6×106 cells/mL with an average growth rate of 21 ×106 cells/mL. The average growth rate of Chlorella sp. in each treatment ranged from 17% – 29%. The growth curve of Chlorella sp. during the 15-day culture showed that the treatment without the addition of eco enzyme in the bean sprout waste extract medium experienced a longer adaptation phase than the others. The quality of water and nutrients during the culture is in a good range for the growth of Chlorella sp. Further research can evaluate the use of eco enzymes for the growth of other microalgae and the and using different organic waste extracts.

Abstract

Kegiatan ini bertujuan meningkatkan pengetahuan dan ketrampilan pembudidaya ikan khususnya yang melakukan aktivitas usaha pembenihan ikan betok (Anabas Testudineus Bloch) secara tradisional melalui kegiatan ceramah dan unjuk kerja.  Pada awal  kegiatan hampir seluruh peserta tidak tahu sama sekali tentang aspek-aspek yang berkaitan dengan krustasea mikro yaitu Daphnia yang hidup di perairan alami serta cara membudidayakannya, dimana rata-rata nilai per responden per pertanyaan sebelum kegiatan penyuluhan (Xrp) adalah 0,304. Namun setelah kegiatan pengabdian ini dilaksanakan ternyata pengetahuan dan ketrampilan pembudidaya ikan meningkat, dimana rata-rata nilai per responden per pertanyaan (Yrp) adalah   3,268.  Berdasarkan uji statistik diketahui terdapat perbedaan yang sangat nyata antara jawaban-jawaban yang diberikan peserta kegiatan pada saat awal dan akhir kegiatan (X2 = 71,1832 > X2 (0,01 = 16,81) ). Dari hasil praktik langsung yang dilakukan oleh peserta kegiatan diperoleh angka pertumbuhan populasi Daphnia  rata-rata sebanyak 1671% dengan jumlah populasi rata-rata sebanyak 5013 ind./liter.

Abstract

The purpose of this study was to analyze the nutritional value of fermented feed on kelakai leaves that are feasible as climbing perch feed and the hematological response of climbing perch raised by fermentation-based feeding of kelakai leaves. The study was carried out using an experimental method on the maintenance of climbing perch which was fed based on fermented leaves with 5 treatments and 3 tests. The parameters observed are the nutritional content of feed based on fermented leaves and hematological responses which include erythrocyte, leukocyte, hemoglobin, and hematocrit values. The results of the research on the nutritional content of feed showed that fermented feed on kelakai leaves has a protein content of 27%-31%, crude fiber content of 4%-7%, water content of 12%-14%, ash content of 11%-13%, fat content of 4%-6%. It was concluded that there was a decrease in fiber content and fat content and an increase in protein content, water content, and ash content. It happens gradually in line with the increase in probiotic dose. The results of the study on the hematological response of climbing perch are erythrocytes range from 1.65-3.91, leukocytes range from 223.23-287.43, hematocrit ranges from 15.30-35.07 and hemoglobin ranges from 5.37-10.33. The results of the proximate analysis of feed based on the fermentation of kelakai leaves showed that the values of water content, ash content, crude fiber, protein, and fat were in the recommended range. The hematological response of climbing perch shows good results and is in the normal range.
