The very close involvement of technology in the banking industry makes almost all banking activities and products currently dependent on information technology (IT). PT BPRS Bhakti Sumekar (PT BBS Bank) is one of the banks that realizes the importance of IT in the digital era and has included IT as part of the company's strategic plan. The company states that compliance with regulations, best practices, and standards is key to a successful IT implementation. In this study, the measurement of the capability level of corporate IT governance was conducted to determine what IT priorities were based on the company's strategic objectives and what recommendations could be given based on best practices to improve IT services in support of the company's strategic goals. The framework to be used is control objective for information and related technology (COBIT); the most widely used framework suitable for service-oriented organizations. The results of research using COBIT 2019 show how IT governance is needed by the company and what should be prioritized. The measurement results found that there is still a gap between management's expectations and the current level of capability and provide recommendations on what companies need to improve performance in order to meet expectations.

Dengan berkembangnya jumlah aplikasi yang terhubung ke Internet, baik desktop maupun mobile, kebutuhan akan aplikasi server yang mampu menyediakan performa yang baik semakin meningkat. Salah satu cara mengoptimalkan performa server adalah dengan memakai bahasa pemrograman yang tepat. Dalam penelitian ini, tiga bahasa pemrograman yang terkait erat dengan web yakni Node.js, PHP, dan Python dibandingkan performanya dengan cara mengukur kecepatan respon serta konsumsi sumber daya komputasi. Dari penelitian ini didapati bahwa Node.js memiliki durasi respon yang paling cepat, sedangkan PHP adalah bahasa pemrograman yang memiliki performa umum yang paling baik.

Mobile application development was growing very rapidly along the increase of mobile devices and technology. One of the problems faced is the different platforms operating system on the market, it is make more difficult development process and requires a lot of cost. An application must be built at least 2 (two) types according to the current popular operating system (Android and iOS) in order to be able to get large application users.Hybrid Application is an application development model that combines native application approach and web application to be a mobile application. It can be converted into more than one mobile operating system platform later. The advantages of hybrid applications is the rapid development process because one source code can run on more than one mobile operating system, while the disadvantage is it use more of resources than the application built with the original language of the operating system platform used.Adobe Phonegap (Phonegap) and React Native are two frameworks that can be used to build mobile hybrid applications. In this study will be compared in terms of development and application results that run on Android devices from each framework by using case studies Aplikasi Jadwal dan Nilai pada Politeknik Kota Malang.

TDMA implementation offer better fairness and throughput in IEEE 802.11. To implement TDMA, new registration process is needed, because current registration mechanism can disrupt TDMA process. This paper proposes a sense-based TDMA registration process using service slot and random timer. Simulation result shows, by using our mechanism, we can reduce the number of unused timeslot, and for 10 new nodes, each node only need 7 ms to complete the registration process.
