Abstract

The purpose of this study is to know and analyze how much influence the brand experience on brand trust and its impact on customer satisfaction of Polo T-Shirt product. Population in this research is every visitor Aeon Mall BSD City met by researcher who was wearing Polo T-Shirt, hence by using unidentified formula obtained by amount of sample counted 100 person. Sampling technique by accidental sampling that anyone who happens to meet can be sampled if it meets the criteria. This research uses an associative-explanatory method. The data used are primary and secondary data. Hypothesis testing is done by using simple linear regression method. Data analysis using statistical data processing software SPSS 22 for Windows. The result of this research shows that brand experience have positive and significant effect to brand trust product of Polo shirt, and brand trust have positive and significant influence to customer satisfaction of Polo T-Shirt product

Abstract

Sub-critical extraction of palm oil from pressed palm fiber using water and preassured carbon dioxide solventwas conducted via the dynamic mode to investigate the ability of water and CO2 to extract α-tocopherol, β-carotene, and phenolic compounds. The yield of palm oil and the solubility of α-tocopherol, β-carotene, andphenolic compounds were investigated at 120; 140; 160; and 180oC and pressure range from 30–100 bar. Theextracted oil was analysed α-tocopherol, β-carotene, and phenolic compounds content using UV–Visspectrophotometry. The results The temperature increase on the process of extracting hydrothermal on thetemperature (120-180oC) increase yield α-tocopherol .The steady to extract α-tocopherol , an acid palmitateand β-carotene on the temperature 180oc with pressure 10 MPa .From the experiment done get the best resulton the temperature 180oC to pressure 10 MPa with yield α-tocopherol 271,28 mg/g sample (% recovery is73,06%), yield pamitate acid 2,066 mg/g sample (% recovery is 0,55% ), and yield β-carotene 0,008 mg/gsample (% recovery is 0,0021 %) as compared to that achieved through conventional palm oil processingindicates that extraction of α-tocopherol, β-carotene, and phenolic compounds using this methode is viable.

Abstract

The aim of this study is to compose curcumin microparticle from temulawak extract (curcuma xanthorrhiza) using SAS (Supercritical Anti-Solvent) method with supercritical CO2. Curcumin is made from temulawak extract that insoluble in water. One of method to increase solubility of curcumin in water is decrease particle size. SAS method is being chosen using supercritical CO2 as anti-solvent because temulawak is perfectly soluble in supercritical CO2. Micronization is performed inside precipitator equipped with filter at the bottom. Temperature is being operated in 35 and 40 oC, and in pressure 8 and 10 MPa. Flow rate ratio supercritical CO2 to solution is 15;0,25 and 15;0,30 mL/min. The results show significant effect of pressure and ratio flow rate Supercritical CO2 to solution on the morphology of micronized curcumin particles. The suitable conditions for curcumin micronization in this work were found to be at 8 MPa, 35 oC and flow rate ratio CO2 to solution is 15;0,25 mL/min.The Supercritical Anti-Solvent (SAS) method could be employed for the micronization curcumin particles. Moreover, the dissolution rate curcumin particles using SAS is higher than unprocessed curcumin particles.

Abstract

Spray drying widely applied in industry for drying the material because it has many advantages including capable to produce particle up to nanometer size, having a continuous process, and high purity. The method that we used in this research is Flame Spray Combustor. This research has the objective to synthesize particles of silica from waterglass and determine the effect of pH on particle silica produced. Analysis of SEM, XRD, and BET was conducted to determine the morphology, crystallinity, particle’s size, surface area and pore size of the silica particles produced. Morphology of silica is small spherical and has an amorphous structure. At pH 8 to 10 the size of silica particles increases with increasing pH, and at pH 11 the size decreases. The higher pH, the smaller surface area of silica particles produced. Meanwhile, the greater pH, the greater pore size of silica particles produced.
