The demand for automotive in Indonesia has never subsided, considering that the human need for transportation greatly affects people's daily lives. Various attempts are made by manufacturers to produce cars of a quality that is comparable to the costs incurred and following market demand. Prediction is a process that can be done to achieve this goal. One of the prediction methods that can be used in this case is the kNearest Neighbor. The prediction process consists of a preprocessing stage that cleans and filters unnecessary variables, followed by a variable multicollinearity test stage with Variance Inflation Factor (VIF). The multicollinearity test found 4 variables that had a specific influence in predicting the VIF value of these variables, respectively 2.22, 2.08, 1.53, 1.10 for Horse Power, Car Width, Highend, and, Hatchback respectively. The four variables of the VIF test results have a positive correlation with the price variable as the dependent variable. The prediction model is made using 4 variables selected based on the VIF test, to determine the accuracy of the method used, the Linear Regression model and, the kNearest Neighbor through the validation test with Mean Absolute Error (MAE) and R2. The kNearest Neighbor method produces an MAE test of 0.06 and R2 results are 0.843. This can be concluded if the overall kNearest Neighbor method has qualified performance in making predictions with continuous value variables or in other words using the concept of regression.

Public opinion is important to agencies or parties in particular fields, as it may indicate a tendency of public's view towards something (such as an object or process). One of them is in the transportation sector. Transportation has become a necessity for the community, many things more effective and efficient online, so that online transportation becomes important for society. The proliferation of online transportation, caused citizens to express opinions through social media. It is important to know the level of service of online transportation considering the large number of users, so that it can be used as a basis for improvement. One of the methods public opinion in social media is by sentiment analysis. The study used the help of Google Machine Learning for the sentiment analysis process that can produce 82,6% of accuracy number, 82,2% of precision, 83,3% of recall with the most sentiment result indicate to public opinion falls into the negative sentiment category for Gojek companies in media social of Twitter.

Providing services to rt / rw net users if done manually will consume a lot of time. Currently this service still used conventional methods even though there are applications that can help but still not efficient in providing the needs of the users such as transactions still using paper based vouchers, which will make it difficult for providers to provide time to handle user transactions. Besides that, there are also a problem where potential users of the service find a hard time to contact the provider because lack of knowledge of some of the provider to edit the mikrotik page to inform about their service and themselves to the user. With the problems mentioned, an application is needed that can provide much easier solution namely, "Design and Building Mikrotik Based Billing System and Chabot as Media Transaction Online". By making this application, it can provide much better solution for user such as getting information and interacting with the admin by using Chabot as media and online transaction to make it easier for users to update their packets and admin to process user transaction.

Bali merupakan salah satu destinasi pariwisata terbaik di dunia. Berdasarkan berita resmi statistik yang dipublikasikan oleh Badan Pusat Statistik Bali, jumlah kunjungan wisatawan mancanegara ke Bali pada bulan Juni 2019 mencapai 549.751 kunjungan. Peramalan kunjungan wisatawan merupakan faktor yang sangat penting untuk menentukan kebijakan tempat tujuan wisata, meminimalkan ketidakpastian dan resiko investasi. Hal ini merupakan hal yang sangat penting karena sektor pariwisata merupakan tulang punggung ekonomi di Bali. Penelitian ini mengangkat topik bagaimana mengimplementasikan metode Triple Exponential Smoothing pada proses peralaman jumlah wisatawan. Kami menggunakan data historis kunjungan wisatawan ke Bali yang diperoleh dari Badan Pusat Statistik Provinsi Bali. Hasil peramalan dievaluasi menggunakan mean absolute error untuk menunjukan rata-rata kesalahan dalam perhitungan peramalan. Rata-rata Mean Absolute Error yang dihasilkan pada peramalan ini adalah 18 dengan hasil evaluasi terbaik dengan menggunakan Alpha 0.9, Beta 0 dan Gamma 0.8.

Berdasarkan berita resmi statistik yang dipublikasikan oleh Badan Pusat Statistik Bali, jumlah kunjungan wisatawan mancanegara ke Bali pada bulan Juni 2019 mencapai 549.751 kunjungan. Peramalan kunjungan wisatawan merupakan faktor yang sangat penting untuk menentukan kebijakan tempat tujuan wisata, meminimalkan ketidakpastian dan resiko investasi. Hal ini merupakan hal yang sangat penting karena sektor pariwisata merupakan tulang punggung ekonomi di Bali. Penelitian ini mengangkat topik bagaimana mengimplementasikan metode Triple Exponential Smoothing pada proses peralaman jumlah wisatawan. Kami menggunakan data historis kunjungan wisatawan ke Bali yang diperoleh dari Badan Pusat Statistik Provinsi Bali. Hasil peramalan dievaluasi menggunakan mean absolute error untuk menunjukan rata-rata kesalahan dalam perhitungan peramalan. Rata-rata Mean Absolute Error yang dihasilkan pada peramalan ini adalah 18 dengan hasil evaluasi terbaik dengan menggunakan Alpha 0.9, Beta 0 dan Gamma 0.8.","PeriodicalId":32334,"journal":{"name":"Jurnal Ilmiah Merpati Menara Penelitian Akademika Teknologi Informasi","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47470961","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}
