The questionnaires were assembled based on 21 instruments which were indicators in this study. The results shows that compatibility does not have a significant effect on perceived usefulness, but it has a significant impact on perceived ease of use. Perceived ease of use has a significant influence on perceived usefulness. Perceived service quality and perceived usefulness have an effect on behavioral intention while perceved ease of use does not have an impact on behavioral intention. Perceived usefulness was simultaneously affected by 50.2%, perceived ease of use was affected with 10.8%, and the behavioral intention variable was simultaneously influenced by 19.2%.","PeriodicalId":434078,"journal":{"name":"Sainteks: Jurnal Sains dan Teknik","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139335271","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}

Temperature, time and pressure in the pressing process in the finishing department play an important role in the quality of the results of pressing garment products at PT X. Various types of main materials used in the garment production process at PT X require different conditions of temperature, time and pressing pressure, so it is necessary to know the appropriate pressing conditions for each type of material. If these three elements are not appropriate, it can give rise to several categories of defects, one of which is often experienced by PT X, namely glossing/shiny defects. The method that used in this research was carried out by experimenting with variations in pressing temperature where the time and pressure variables used were fixed. The temperature variations used in this research include 600C, 700C, 800C, 900C and 1000C.. This research aims to determine the optimum temperature that used in the pressing process in making Bigborn 2-Tuck Pants Style 3651 trousers with the main material composition being 65% Polyester and 35% Katun. The pressing results are then tested for the tensile strength of the fabric towards the warp and towards the weft of the fabric. Based on the experiments carried out, it shows that for temperature variations of 600C and 700C there are poor press defects. At varying temperatures of 800C and 900C, there are no glossing defects. At 1000C it has glossing/shiny defect. Next, to obtain the most optimum temperature conditions, the experiment continued with testing the tensile strength of the fabric. Based on the fabric tensile strength test data, an optimum temperature condition was obtained in the process of pressing Bigborn 2-Tuck Pants Style 3651 trousers, namely at a temperature of 800C. The tensile strength results obtained at a temperature of 800C were 55 kg for the tensile strength of the fabric in the warp direction and the tensile strength of the fabric in the weft direction was 45.5 kg.

ACO performance is influenced by it’s parameter value. The number of ants parameter has a strong influence on ACO Performance, because it influences directly on solution quality and computation time. It is too hard to find the parameter value that can make ACO performance being the best performance. Because of this, what can be done is to test several parameter values, then compare the ACO performance of each parameter value. Russia-20-Nodes-SDVRP Instance is attractive to be solved because it’s number of nodes are not too many, only 20 nodes. Based on that number of nodes, the computation time of this instance is relatively fast and it has a lot of solution candidate. This research focus on the ant number effects on ACO for Solving Russia-20-Nodes-SDVRP Instance. Five ant numbers will be tested, they are 5, 10, 15, 20 and 25 ants, each ant number will be tested 10 times, so there will be 50 tests. These tests show that more ants used, greater possibility of getting a better route, but longer calculation time needed.

Intuitive decision-making is highly discouraged if it is not from a reliable source because the level of deviation that occurs can be very large. Therefore, we need a reliable basis for making a decision. The D'Amerta Berniaga business group does not use online media to carry out its business. This has resulted in the underdevelopment of the business being carried out, given the increasingly fierce business competition at this time. However, the decision to use online media is very difficult considering that business owners are housewives and sole implementers in their businesses. This resulted in an increase in workload and a very large amount of time to use online media, causing doubts about the decisions to be taken. Therefore, training on the use of online media was carried out in an effort to overcome this problem. The existence of training makes business owners interested in using online media. The business owner's decision to use online media needs to be evaluated to determine the accuracy of the decisions taken. This study aims to see whether the decisions taken by business owners, namely using online media, are appropriate and able to contribute to their business. The method used is a quantitative method with a descriptive approach. Measurements were made based on the total population of 30 respondents by pretest-posttest.
