Tour packages, or what can be called package tours or inclusive tours, are forms of travel that have one or more destinations and are supported by various travel facilities. Tour packages can usually be purchased through travel agents or on the spot at tourist destinations, for example, directly at tourist villages that have tour package offers. The tour packages offered vary with different prices and specifications. The various choices of tour packages offered sometimes make tourists confused about choosing the right tour package. This is because the prices are not in accordance with the tourist budget, and the schedule is not flexible. Tourists are required to be precise in making decisions so that the selected tour package is as desired. For this reason, it is necessary to have a system that helps in providing alternative choices of tour packages. A decision support system (DSS) is one of the tools that can be used in decision-making for decision-makers. From several decision-making methods in this study, a comparison of two methods, namely TOPSIS and MARCOS, was carried out to determine tour packages according to tourist criteria. These two methods were chosen because they have similarities in the calculation concept, which is related to the ideal solution and the anti-ideal solution. Comparisons are made using the total budget and total time parameters. The test was carried out using 10 trial data entered by tourists and then the tourist objects themselves, namely samples of natural, culinary, and shopping attractions in Badung Regency. The test results show that the MARCOS method is better than the TOPSIS method because it produces 7 test data with a better total budget and total time.

Grammatical competence is a skill that is generally taught integrally into the teaching of active English competence in the scope of English for Specific Purposes (ESP) in the Informatics Management Study Program. Thus, students do not get maximum exposure to grammatical teaching even though grammar is a basic competency that plays an important role in determining the quality of speech and writing produced. Students need to be equipped with digital learning tool, i.e., grammar learning application to support their autonomous learning process. This research focuses on the implementation of a mobile-based grammar application for computer students that is used as a self-directed learning tool. The implementation phase was carried out using an experimental research method which was applied to English courses at Informatics Management with 84 participants. Quantitative data were obtained from the results of the pre-test and post-test in grammar before and after the integration of the grammar application. The results of the pretest and post-test assessments were analyzed using the One-Sample Kolmogorov-Smirnov Test to test the normality and paired sample t-test to analyze the effect of using the application on improving student achievement. In addition, qualitative data was gathered using google form. The results of the questionnaire were analyzed to determine students' perceptions of the autonomous grammar learning process. The analysis of both quantitative and qualitative data reveals that students gained a deep grammar learning experiences and could enhance their grammar competence.
