Abstract

Road is the land transportation that has an important role to facilitate all human activities, while tropical climate condition such as in Indonesia causes damage to the road. To engineer the hot asphalt mixture in order to have high durability, especially in Type IV Asphalt Concrete, it needs additional material to it, such as roadcel-50 cellulose fiber. However, it is considered not economical because the cellulose fiber made by the factory is quite expensive. Therefore, the researcher wants to replace it with water hyacinth fiber obtained from the river in the area of Dinoyo, Deket District, Lamongan Regency that not yet widely utilized. The mixing process of Type IV Asphalt Concrete with water hyacinth additional material starts from preparing the tools and materials, making the simple water hyacinth fiber, examining the stacking materials (including examining the coarse aggregate, fine aggregate, and asphalt), making Job Mix Formula of Tipe IV Asphalt Concerete and making the test objects of Type IV Asphalt Concerete. From the results of Marshall Test, the researcher analyzed the results with regression analysis. The results obtain 6 characteristics that meet the standard with water hyacinth mixing, those are marshall stability of voids mineral aggregate, voids in mix, density, flow, and marshall quotient with the addition of an ideal water hyacinth fiber variation of  0,02% - 0,06%. While on the voids filled with asphalt test on Marshall Test obtained the result that does not meet the requirements, but it does not matter to the whole result.

Abstract

Customer satisfaction is important in the business world, especially in the service sector (Khaliq, 2018). Most of the literature considers providing quality services as an important strategy for the survival of companies, in this case private commercial banks. Moreover, private banks must be able to compete with state-owned banks and foreign banks. Apart from customer satisfaction, commercial banks also run a trust business . Trust in this case is a good relationship between the bank and its customers (Suwarman, 2013; Sangadji & Sopiah, 2013). This research is a type of quantitative research with Partial Least Square (PLS) statistical analysis. Data was obtained through a survey with a research instrument in the form of a questionnaire of 112 respondents. From the results of this research, results were obtained which stated that the variables Brand Image and Service Quality had a significant positive effect on Customer Satisfaction and Trust in private commercial banks in Lamongan.
