This study uses a quantitative descriptive method. The number of samples in this study was 125 respondents. The respondents in this study were users of cargo services at I Gusti Ngurah Rai International Airport. Determination of the sample using accidental sampling technique is a technique of determining the sample by taking respondents who happen to be available or available somewhere according to the research context. Data collection techniques by giving questionnaires to respondents, observation, and documentation. Meanwhile, to analyze the data, the Normality, Heterodicity, Linearity, Simple Regression, and t-tests were carried out using the SPSS 22.00 program. The research results show that: 1) The quality of cargo services is in the high category of 75.2%, the moderately high category is 24.8%, the moderately low category is 0% and the low category is 0%. Satisfaction of cargo service users is in the high category of 96.0%, quite high category of 4.0%, moderately low category of 0%, and low category of 0%. The loyalty of cargo service users is in the high category of 76.0%, quite a high category of 23.2%, moderately low category of 0.8%, and low category of 0%. 2) There is an effect of the quality of cargo services on the satisfaction of cargo service users as shown by the results of the t-test where the probability value (sig.) is 0.00 so that the value is less than the standard error value which is 0.05. 3) There is an effect of the quality of cargo services on the loyalty of cargo service users as shown by the results of the t-test where the probability value (sig.) is 0.016 so the value is less than the standard error value which is 0.05.","PeriodicalId":40576,"journal":{"name":"Revista Vortex-Vortex Music Journal","volume":"103 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85976652","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}

This study aims to determine the stages or processes of agel leaf natural fiber composite using 2 methods of hand lay up, vacuum bag and to determine the value of the bending strength of agel leaf natural fiber material between variations of the epoxy matrix in the direction of the fibers 0^° and 〖90〗^°.Based on the data from the test results, it can be concluded that the average value of maximum bending strength in agel leaf natural fiber composites using the vacuum bag manufacturing method with a volume fraction of 60% and fiber direction 0^° and 〖90〗^° has an average maximum bending strength value that is the highest, namely 11.006 MPa and 11.057 MPa and the composite of agel leaf natural fiber using the hand lay up method (non vacuum bag) with a volume fraction of 50%, 60%, 70% and fiber direction 0^° has the lowest average maximum bending strength values of 3.413 MPa, 5.404 MPa, 4.625 MPa.","PeriodicalId":40576,"journal":{"name":"Revista Vortex-Vortex Music Journal","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77612975","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}

These cause the use of energy on the earth is increasing. One effort to obtain energy sources is to utilize solar energy using solar water heater. This research was expected to help the society to save energy derived from fossils. A testing was conducted by designing solar water heater with collector size of 60 cm x 50 cm using black painted aluminum-coated styrofoam insulator and the storage tank made of stainless steel with volume of 40 liter using black painted aluminum-coated styrofoam. In conducting the testing, the data were taken at 09.00 a.m until 04.00 p.m for 5 days. The research was conducted at ITD Adisutjipto. The analysis and discussion showed the solar water heater design and the storage tank used to perform performance the test (efficiency). Within 5 days testing the average of water temperature out (Tout) was 59.75 oC to 76.59 oC with the average rate efficiency of 54.07 % to 54.9 % and the average storage drop rate of 2.97 K / Hr or 17.84 K for 6 hours","PeriodicalId":40576,"journal":{"name":"Revista Vortex-Vortex Music Journal","volume":"12 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80907555","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}
