    Highlight Research • There has been a significant decrease in growth, condition factors, hepatosomatic index along viscerosomatic index with the length of time for feed restriction, although fasting for up to 28 days did not cause fish mortality • Hematological parameters such as RBCs, WBCs, hematocrit, and hemoglobin decreased significantly, but after re-feeding increased significantly in consecutive times • The blood glucose levels decreased during feed restriction and gradually increased after re-feeding • Feed restriction ï¬sh gained weight continuously during re-feeding, but no displaying compensatory growth • The decrease in hematological parameters did not indicate stress levels in fish, but reflected a lack of nutrition condition   Abstract The management of red tilapia culture can be improved through restriction of feed. This study aimed to determine the impact of feed restriction time and re-feeding on the growth and hematological performance of juvenile red tilapia. This study used an experimental method with a completely randomized design consisting of five treatments with four replications, namely the fish were given food for 28 days (A), 7 days of feed restriction followed by 21 days of refeeding (B), 14 days of feed restriction followed by 14 days of refeeding (C), 21 days of feed restriction followed by 7 days of refeeding (D) and 28 days of feed restriction (E). The parameters observed were growth, biometry, and hematological values. The results showed that during the feed restriction period there was a significant decrease in growth, condition factors, hepatosomatic index along with viscerosomatic index with the length of time for feed restriction, although fasting for up to 28 days did not cause fish mortality. Hematological parameters such as RBCs, WBCs, hematocrit, and hemoglobin decreased significantly, but after re-feeding, they increased significantly in consecutive times. As for the blood glucose levels decreased during feed restriction and gradually increased after re-feeding. This study stated that feed restriction ï¬sh gained weight continuously during re-feeding, but no displaying compensatory growth. The results suggested that the decrease in hematological parameters did not indicate stress levels in fish, but reflected a lack of nutrition condition

    High fluctuations in stock returns is one problem that is considered by the investors. Therefore we need a model that is able to predict accurately the volatility of stock returns. One model that can be used is a model Autoregressive Conditional Heteroskedasticity (ARCH). This model can serve as a model input in the Support Vector Regression (SVR) model, known as Hybrid ARCH-SVR. This modeling is one of the alternatives in modeling the volatility of stock returns. This method is able to show a good performance in modeling the volatility of stock returns. The purpose of this study was to determine the stock return volatility models using a Hybrid ARCH-SVR model on stock price data of PT. Indofood Sukses Makmur Tbk. The result shows that the determination of the input variables based on the ARIMA (3,0,3)-ARCH (5), so that the SVR model consists of 5 lags as input vector. Using a this model was obtained that the Mean Absolute Percentage Error (MAPE) of 1,98% and R2 = 99.99%. Keywords: ARCH; ARIMA; SVR; Volatilit

    A rice husk-based active carbon modified using SLS surfactant showed an increase on Pb ionic metal removal with the efficiency of 99.96%. Activated carbon is commonly applied as adsorben in waste water treatment, in particularly, waste water containing heavy metals and dye molecules. Even though it is commonly used, the adsorption efficiency of activated carbon to the heavy metal waste is still low. Therefore, in the present work, carbon from rice husk was modified using surfactant which further it is called surfactant modified active carbon (SMAC). Firstly, rice husk-based carbon was activated using 40% H3PO4 for 2, 6, 10, 14, 15 and 16 hours. The activated carbon was then modified by contacting it into SLS in different concentration 10, 20, 30, 40, 50, 60 and 70 ppm for 5 hours. Finally, the SMAC was then applied to remove Pb ionic metal. Moreover, several characterisation techniques were performed including FTIR, SEM, UV-Vis and AAS. Keywords: activated carbon, surfactant-modified active carbon, adsorption, rice hus
