This research uses the Structural Equation Modeling (SEM) method to test the validity and reliability of adapted scales. There are five stages starting with an outer model test to test the validity and reliability of the questionnaire's feasibility. The population in this research are organizations that are affiliated with the Indonesian Business Incubator Association (AIBI) and Ministry of Research, Technology and Higher Education, including business incubators belonging to ministries, local governments, the private sector and universities, there are 182 Technology Business Incubators in Indonesia. Testing in this research looks at whether the questions in the questionnaire are valid or not by going through two stages of convergent validity and discriminant validity. The first stage is convergent validity that aim of finding out the correlation between indicators and their latent variables. The second stage is discriminant validity which aims to find out whether the latent variable has adequate discriminant value and this was done to find out whether the statement items in the questionnaire were reliable and consistent in measuring the same symptoms in respondents. This research looks at the results of convergent validity analysis to consider the results of factor loading indicators on relevant factors, the results of testing the validity of all factors with a value greater than 0.50, one of which is an AVE value of 0.550, indicating that the indicators in these variables have a strong contribution in measuring the desired construct, and the reliability test of all variables is reliable because it exceeds 0.70, one of which is the facility variable which has a value of 0.858.

The materials used are TEMPO ((2,2,6,6-tetramethylpiperidine-1-oxyl)), Bacterial Cellulose, and Polypyrrole (Ppy). This research aimed to increase the material's current density and specific capacitance values using the drawing method. Composite nanomaterials are made by oxidizing BC (Bacterial Cellulose) with TEMPO. The resulting TOBC (TEMPO Bacterial Cellulose) material was mixed with Ppy using the in situ method. The mixture is then drawn wet—measurement of current density and capacitance using Cyclic Voltammetry (CV) Testing. The current density and specific capacitance results increased by 542.74% and 754.79% after drawing the nanocomposite material. It is directly proportional to the effects of characteristic testing, which includes SEM, XRD, and FTIR. As a result of the withdrawal of the polypyrrole, it will be more evenly distributed in the composite material, absorbing and coating the nata de coco. The researchers concluded that when the TOBC/Ppy fibers are straighter and denser, they achieve higher current density and capacitance values.","PeriodicalId":505468,"journal":{"name":"Andalasian International Journal of Applied Science, Engineering and Technology","volume":"218 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140719741","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
