Abstract

Sifat Listrik Film Tipis SrTiO3 untuk Kapasitor MOS An anti-tumor calcon has been isolated from Criptocarya costata stem bark. The compound was obtained from chloroform fraction fractioned by chromatography technique and recrystalized in n-hexane and ethyl acetate. The compound structure elucidated based on physical and spectroscopic data was 2,4-dihydroxy-3,5,6-trimethoxy calcon. Cytotoxic assay using murine leukemia cell P388 showed positive activity with IC50 value of 3.65 µg/mL.

Abstract

Pterospermum subpeltatum C.B. Rob or bayur is traditionally and widely used as medicine for infection diseases caused by bacteria. Four extract from root stem of this plant were evaluated for their antibacterial activity properties against Escherichia coli, Shigella boydii, staphylococcus aureus danStreptococcus mutan. All the extract were able to inhibited the bacterial strain except Staphylococcus aureus. Chloroform extract exhibited effect for Shigella boydii and Streptococcus mutan. Hexana extract for Escherichia coli, while methanol extract for Shigella boydii. All extract showed an effect at the same extend (MIC; 50 mg/ml).

Abstract

The technology of diversifying the processing of komo tuna fish pulp, which is nutritious and rich in fiber, is carried out by adding cottonii, Spinosum, and Gracilaria types of seaweed flour. In this paper, we will discuss the effect of adding cottonii, Spinosum, Gracilaria seaweed flour to the nutritional content (protein, and ash content) of komo tuna (Euthynnus affinis) amplang, and the panelists' preference for komo tuna (Euthynnus affinis) amplang. seaweed flour (cottonii, spinosum, gracilaria) was added through hedonic test. The method used is an experiment with the main stages covering the preparation of raw materials, making seaweed flour, making komo tuna fish amplang. The results obtained were the addition of seaweed flour (cottonii, spinosum, gracilaria) had an effect on the protein content and ash content of amplang komo tuna (Euthynnus affinis). The protein content of tuna Amplang is 25.9% for the addition of Cottonii type seaweed, while the ash content does not meet the SNI standard for the addition of seaweed to Amplang. Amplang organoleptic test obtained the highest number of appearances in the treatment without the addition of seaweed flour, then followed by cottonii, spinosum and finally gracilaria seaweeds, as well as the high textural values in the treatment without the addition of seaweed flour.

Abstract

This study aims todetermine the appropriate ratio between the water and fruit juice as well as the mass of the alginate powder as well as organoleptic test results tamarillo Powder . The method used to study the tamarillo powder is a volume ratio of water : fruit juice ( 1 : 1 , 1 : 2 , 1 : 3 ) with the addition of alginate 0.1 g , 0.2 g , 0.3 g . Analysis was conducted on the organoleptic ( flavor , aroma , color , texture ) and humidity . Based on the research results of data processing tamarillo powder obtained the best results of the organoleptic analysis through expert panelists that the volume ratio of water : fruit juice ( 1 :1 ) with the addition of 0.1 g alginate which give a sense ( strong acids and sweet-sour ) , aroma tamarillo powerful , purple –brown color , and relatively coarse texture with a water content of 0.05 % .

Abstract

Pulping process from water hyacinth (eichronia crassipes) is done by using soda proces, where pulping process starting with the preparation of raw materials, cooking process using NaOH solution, washing with water, filtering and drying then analyzed to determine the quality of the pulp. The dried pulp is bleached using chorine.The Variable concentration of NaOH cooking solution 7%, 9%, 11% and cooking time 90, 120, 150 minutes are the variable which used to determine its effect on the quality of the pulp produced. Meanwhile, the parameters tested to determine the pulp quality are yield (% yield), moisture content and physical strength of the pulp.On this research were obtained that the optimum concentration at 7% and cooking time at 90 minutes with % yield of 17,167% , moisture content 9,615%, tensile strength (Force) 25,47 N and voltage (σ) 2,461 MPa.
