Abstrak Dalam dunia transportasi khususnya penerbangan banyak sekali hal menarik yang bisa dianalisa maupun diperbarui, contohnya dalam menilai kepuasan penumpang maskapai sebagai evaluasi maupun mengetahui seberapa besar kepuasan pelanggan dalam menggunakan transportasi penerbangan tersebut. Karena alasan inilah sehingga peneliti akan melakukan penelitian mengenai hal tersebut di atas dengan menggunakan algoritma Naïve Bayes, dimana pengukuran tersebut diukur dengan 16 variabel pengukur dan 1 variabel respon. Digunakan dataset sebanyak 129.880 record untuk selanjutnya dari dataset tersebut akan dibagi menjadi data training dan data testing, dimana pembagian data tersebut akan dibuat dalam 4 kondisi yaitu 90%, 85%, 80% dan 75% untuk masing data training dan sisanya adalah data testing sehingga dapat dilihat dari keempat pembagian ini manakah yang memiliki tingkat akurasi yang paling tinggi. Dari proses analisa menggunakan algoritma Naïve Bayes yang dilakukan dengan aplikasi KNime, didapatkan bahwa pembagian data training 90% dan Data Testing 10% adalah hasil akurasi tertinggi dengan persentasi akurasi sebesar 81,466%. Dengan hasil ini maka 16 variabel pengukur yang ditetapkan peneliti dapat dijadikan sebagai sebuah acuan untuk mengukur tingkat kepuasan penumpang maskapai penerbangan.
The use of Information Technology (IT) at a university is needed at this time. There are many advantages in using IT and have a good impact on a university. The use of IT in a university has different roles according to their needs. The utilization of IT in Higher Education theoretically provides appropriate and efficient administration systems (Fernandes Andry and Christianto, 2018). IAIN Palangka Raya is one of the universities that has implemented IT, in this case, the academic and student management information system. The information system at IAIN Palangka Raya is one of the IT applications that is often used to carry out IT governance, however, there are several problems that occur in the information system, including features or tools that are not yet functional. For this reason, the researcher will analyze the information system to get the level of maturity and recommendations so that IAIN Palangka Raya can follow up on the results of this analysis and improve it to get the goal of good information system governance. In this study, the COBIT 5 framework is used with a focus on the EDM domain (Evaluate, Direct, and Monitor). The results of the analysis showed that the capability level was 2.86 (established), which means that the process was carried out, achieved goals, and well managed. With a balance value of 0.96, which means that the expected distance with the current distance is not too far so that features or tools that are not yet functioning are functional. So that the academic and student management information system of IAIN Palangka Raya runs according to its goals and is better.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
