Abstract

This study aimed to analyze the performance of tiger prawn Penaeus monodonseed which were fed taurine-enriched Artemia. The study was conducted by using a completely randomized design.The treatment in this research was taurine enrichment dosage of Artemiathat consist of 4 levels: 0 gL-1 (DPT-0), 0.5 gL-1 (DPT-0.5), 1.0 gL-1 (DPT-1.0) and 1.5 gL-1 (DPT-1.5) in triplicate. Larvae stocked at a density of 50 individu.L-1 were fed Artemianauplii from Mysis-3 to PL-12 stages. Measurement and analysis data to compare the effects of these treatments were tested by analysis of variance (ANOVA) followed by Duncan's multiple range test at a significance level of 0.05. The results showed that the taurine content of Artemia increased significantly and linearly with the enrichment dose of taurine. Furthermore, the specific growth rate and visual quality of larvae increased significantly by feeding taurine-enriched Artemiaof 1.0 gL-1, but increasing the taurine enrichment dose to 1.5 gL-1 in the Artemia was not followed by an increase in these parameters. The vitality and resistance of larvae increased significantly and linearly with increasing in taurine enrichment dose, whereas the survival rate for larvae only increased significantly with 0.5 gL-1 taurine-enriched Artemia. Based on these results, the best post-larval performance of tiger prawns was obtained by feedingArtemia enriched with taurine 1.0–1.5 gL-1.

Abstract

This study aimed to determine the effect of urea added with organic matter in a high C/N (50-70) or low C/N (10-20) ratio on the hydraulic conductivity and electrical conductivity of Ultisol soil. The research was arranged in a Split Plot Design. The main plot is organic matter, ie, without organic matter, calopogonium leaves, and rice straw 1,275 x 10-8 kg/ha, equivalent to 15.3 g/pipe. Sub-plots were urea doses consisting of 0, 100, and 300 kg/ha, equivalent to 0 g/pipe, 0.0425 g/pipe, and 0.0825 g/pipe, respectively, applied to Ultisol soil. Sample of Ultisol soil was taken at a depth of 0 -120 m which were air-dried, then sifted, mixed with TSP, organic matter, and urea according to treatment. The sample was put in a PVC tube (pipe) with the bottom covered with fine gauze to hold the soil but still allow percolation. . Incubation was carried out for two weeks. Observations were made after the incubation period, including hydraulic conductivity and electrical conductivity. The application of organic matter and urea at a dose of 300 kg/ha can increase the electrical conductivity of the soil. Adding the main organic matter with a high C/N ratio (rice straw) increases the hydraulic conductivity. Electrical conductivity (EC) is a good indicator in explaining the dispersive effect of urea and the effect of flocculation of organic matter. High electrical conductivity always results in high hydraulic conductivity in Ultisol soils.

Abstract

The demand for mustard plants has not met the demands of the community because its productivity is still relatively low. Agricultural land, especially in urban areas is getting narrower, less labor in agriculture, and reduced nutrient availability in the soil are the main reasons for low productivity. In addition, the use of chemical fertilizers by farmers and the high rainfall in Sorong City are also the cause of the low production so that the community's needs are not fulfilled. Therefore, research was conducted with the aim of increasing the yield and quality of mustard plants by using a floating raft hydroponic cultivation system by utilizing stale rice into liquid organic fertilizer. This study used a randomized block design (RAK) with 4 treatments each repeated 3 times. The treatment is by giving fermented stale rice, 0 gr (control), 100 gr, 150 gr, and 200 gr. The difference in the concentration of liquid organic fertilizer of stale rice has an effect on plant growth, namely the increase in plant height, number of leaves, root length, leaf area, and wet weight by the floating raft hydroponic technique. Liquid organic fertilizer treated with 200 g of fermented stale rice gave the best effect on the growth of mustard plants using floating raft hydroponics.
