Abstract

ABSTRAKThis research was conducted from February to April 2019, at the Laboratory of Technical Services Unit Aquaculture of Technology, Faculty of Fisheries and Marine University of Riau. The purpose of this study was to determine the frequency of the addition of appropriate probiotics in culture of baung (Hemibagrus nemurus) on peat swamp water media with biofloc technology. This study used completely randomized design (CRD) of one factor consisting of five levels of treatment with three replications.  The treatments applied are (1) once every 5 days, (2) once every 10 days, (3) once every 15 days, (4) once every 20 days, (5) control with a dose of 10 ml/m3 This is able to increase the growth and survival of baung fish (Hemibagrus nemurus), namely by growth in absolute weight 4.12 g, absolute length 4.43 cm, specific growth rate 2.37% feed conversion ratio 0.89, survival rate 83.33%, volume flock 12.5 ml/l. Water quality parameters such as: temperature in all treatments ranged from 26-29 °C, pH ranged from 6.6-7, dissolved oxygen ranged from 5.7 to 6.0 mg/l, and ammonia ranged from 0.003 to 0.112 mg/l.Keywords: Probiotics, Biofloc, Growth, Survival, Baung Fish.

Abstract

A study was conducted at the Plant Introduction Center (PIC), Southern Agricultural Research Center (SARC), Pakistan Agricultural Research Council (PARC), Karachi for the effect of Organic {Neem Seed Powder (NSP) and Gliricidia sepium leaves (GSL)} and Inorganic {(Urea (N), Di-ammonium phosphate (P) and Murait of potash (K), (NPK)} Fertilizers Amendments on Inflorescence and flower Morphology and Yield of Coconut. The experiment consist of eight treatments namely; T1 (NPK + NSP + GSL), T2 (NPK+ NSP), T3 (NPK+ GSL), T4 (NSP + GSL), T5 (NPK), T6 (GSL), T7 (NSP), T8 control without treatments. The experiment was laid down as Complete Randomized Block Design replicated three times. The results demonstrated that the number of spikelets with female flowers were significantly high in T1 to T7 as compared to T8 treatment. The 1st spikelets with number of female flowers (48.97) were significantly (p<0.05) high in T1 as compared to T2, T3, T4 and T8. In case of stalk length (38.05 cm) it was significantly (p<0.05) high in T1 as compared to T8. The findings of the study indicated that the number of nuts (99.33) and fruit weight (1490.77 g) were significantly (p<0.05) highest in T1 as compared to T3 to T8 and T2 to T8 treatments, respectively. The T1 treatment also showed better fruit length (25.75 cm), fruit breadth (42.97 cm), husk weight (448.66 g), shell weight (278.11 g), kernel weight (434.22 g) and nut water (188.77 ml) with significant differences in some of the treatments. The application of organic amended with inorganic fertilizers, enhanced the growth and nut production in nutrient deficient soils. It is therefore, recommended that treatment T1 {NPK+NSP+GSL)}/palm/year was enough to improve the morphological, inflorescence, flower morphology, high nut production, better income to coconut farmers, economical and beneficial for conservation of coconut genetic resources in coastal area of Pakistan.

Abstract

Irregular and complex behavior in the financial system can disrupt stability and smooth economic growth. It causes randomness within the system, generating chaos; hindering synchronization behaviour. Achieving smooth and rapid synchronization between two coupled hyperchaotic finance (HF) systems with lessened fluctuation of input and output signals is vital for continuing financial stability and fostering economic growth, a challenge addressed in this article. The paper proposes a novel time-efficient nonlinear control (TENLC) technique and investigates HF systems synchronization using the drive-response system (DRS) arrangement. The proposed TENLC strategy realizes fast and smooth synchronization behaviour between two coupled HF systems, reducing closed-loop state-variable trajectory oscillations. The controller is designed to retain the nonlinear components within the closed-loop system and does not depend on the system's parameters, simplifying the design and analysis process. The Lyapunov stability technique confirms the closed-loop's global stability at the origin. Proofs of mathematical analysis and computer-based simulation results validate the theoretical findings, showing that the presented TENLC strategy converges the state error trajectories to zero in a short transient time with lessened fluctuations for all signals. The comparative computer-based simulation analysis confirms that the presented TENLC approach outperforms other synchronization control techniques.
