Effects of Dietary Caulerpa lentillifera Supplementation On Growth Performance and Survival Rate of Milk Fish, Chanos chanos (Forsskål, 1775)
Abstract: The study aimed to investigate the dietary supplementation effect of sea grape, Caulerpa lentillifera, on the growth performance and survival rate of milkfish, Chanos chanos (Forsskål, 1775). Two hundred fish weighing in the range of 0.20-0.25 g/ind were randomly distributed into 20 of 25 L tanks. The 0 (control), 10, 20, 30, and 40 g/kg of Caulerpa lentillifera powder was supplemented into four formulated feeds and then fed for 49 days. The result exposed that the administration of Caulerpa lentillifera powder in the diet provided a significant effect on the absolute weight gain, absolute length gain, specific growth rate, and feed efficiency (P0,05). The optimum specific growth rate, absolute weight, absolute length and feed efficiency were found at treatment C (20 g/kg diet) with the values of 1.597±0.137 %/days, 4.47±0.08 g, 2.98±0.77 cm and 69.86±2.72 %, respectively. Regarding this result, the supplementation of sea grape (Caulerpa lentillifera) at a 20 g/kg diet is recommended to obtain the optimum growth of milkfish (Chanos chanos).Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh suplementasi pakan anggur laut Caulerpa lentillifera terhadap performa pertumbuhan dan kelangsungan hidup ikan bandeng, Chanos chanos (Forsskål, 1775).

Traditional and complementary treatments among Malay, Chinese and Indian chronic diseases: a systematic review
Although the modern medicine has progressed for a long time, there are empirical studies shows the effectiveness of traditional and complementary treatments (TCT) in curing chronic diseases. In Malaysia, TCT is often related to the use of herbs and meditation that vary according to ethnicity. Each ethnic group has its own beliefs system in curing diseases. This study mainly aims to provide an overview on the perceptions of the effectiveness TCT in curing chronic diseases. The authors used electronic database to select 10 journal articles according to inclusion and exclusion criteria. Findings show the highest statistic among Sabah natives and followed by Malay ethnic on believing in the effectiveness of TCT. Price and encouragement from family and friends are the main influencing factors of taking TCT. We suggest that counsellors need to be aware of the TCT practices on particular culture in order to increase respect and trust in the helping relationships
Biocatalytic Reduction of Formaldehyde to Methanol: Effect of pH on Enzyme Immobilization and Reactive Membrane Performance
Thermodynamic stabled CO2 molecules can be biocatalytically reduced to methanol via three cascade dehydrogenases (formate, formaldehyde and alcohol) with the aid of cofactor as the electron donor. In this study, Alcohol dehydrogenase (EC 1.1.1.1), the third step of the cascade enzymatic reaction which catalyzed formaldehyde (CHOH) to methanol (CH3OH) will be immobilized in an ultrafiltration membrane. The enzyme will be immobilized in the support layer of a poly(ether)sulfone (PES) membrane via a technique called fouling induced enzyme immobilization. The objective of this study is to evaluate the effect of varying pH (acid (pH 5), neutral (pH 7) and alkaline (pH 9)) of the feed solution during immobilization process of ADH in the membrane in terms of permeate flux, observed rejection, enzyme loading and fouling mechanism. The experiment was conducted in a pressure driven, dead-end stirred filtration cell. Reaction conversion and biocatalytic productivity will be also evaluated. The results showed that permeate flux for acid solution were the lowest during immobilization. High concentration polarization and fouling resistance cause lower observed rejection for pH 7 and 9. Enzyme loading for pH 5 give 73.8% loading rate which is the highest compared to 62.4% at pH 7 and 70.1% at pH 9. Meanwhile, the conversion rate during the reaction shows that reaction on fouled membrane showed more than 90% conversion for pH 5 and 7. The fouling model predicted that irreversible fouling occurs during enzyme immobilization at pH 7 with standard blocking mechanism while reversible fouling occurs at pH 5 and 9 with intermediate and complete blocking, respectively.
