This study aims to analyze the effect of the Covid-19 pandemic on the applications and student expenditure during the pandemic. The Covid-19 pandemic caused the government through the Ministry of Education and Culture to announce teaching and learning activities carried out from home using the online method. There are several complaints with the use of online methods, one of which is opinion about the increase in fees for the purchase of data package pulses. The opinion said that student spending increased due to the purchase of data package pulses. This study tries to conduct a survey and analysis specifically comparing student costs before and after co-19. During a pandemic, students spend more credit than before the pandemic which is 10.8% on topping up. But it was revealed that spending on pandemic students was less than before the pandemic with the smallest percentage of 46.9%. While applications that are often used in online lecture methods are Google Classroom with 74.7%, Zoom 67%, and WAG 35.3%. It is hoped that this initial research can support and provide input to policy makers in education institutions during lectures during the pandemic.

The library is an important part of higher education, where the teaching and learning process does not escape from teaching materials and reference materials. Qamarul Huda Badaruddin University is one of the universities in NTB which has a library with a desktop-based library system. This has an impact on the management of libraries and users which in this case students become ineffective and inefficient. With a high need for libraries, library managers, namely librarians and students as users, need a web-based information system so that they can be used from anywhere and anytime, simply using a smartphone or computer. To answer the above problems, the authors design and build a web-based library information system at Qamarul Huda Badaruddin University using the Rapid Application Development (RAD) method. The framework uses CodeIgniter which allows developers to create web applications with Rapid Application Development (RAD) development characteristics. The Qamarul Huda Badaruddin University Library Information System consists of 12 functional requirements, which cover all the requirements for the Qamarul Huda Badaruddin University library. Completion of each module also refers to all stages of the Rapid Application Development (RAD) method and all of them can run well

Ad Hoc Network adalah jaringan wireless yang terdiri dari kumpulan node bersifat dinamik yang dapat saling berkomunikasi. Node tidak hanya berfungsi sebagai pengirim dan penerima informasi data tetapi juga berfungsi sebagai jalur jaringan tempat informasi data yang terkirim. Mobile Ad Hoc Network (MANET) adalah kumpulan dari beberapa wireless node yang dapat diatur secara dinamis di lokasi manapun dan tidak terbatas waktu tanpa menggunakan infrastruktur jaringan yang ada. MANET tidak memerlukan pusat administrasi dan infrastruktur kabel. MANET pada mobile host yang terhubung dengan wireless dapat bergerak bebas dan juga berperan sebagai router. Makalah ini memberikan wawasan tentang karakteristik MANET, aplikasi potensi dalam memanfaatkan teknologi MANET sebagai Alat Komunikasi Data Transportasi di Indonesia.

Revolusi Industri 4.0 salah satunya Teknologi Informasi telah menghasilkan inovasi yang lebih cepat dalam berbagai bidang. Sejak tahun 1990an, peranan Teknologi Informasi menghasilkan pengembangan dan penerapannya pada bidang Ilmu Kesehatan. Salah satu penerapan teknologi informasi pada bidang Kesehatan adalah Telemedicine. Pada perkembangan lanjutan, yakni IoT (Internet of Things) sudah mulai diterapkan pada analisis rekam medik. Selama beberapa tahun terakhir, telah dicoba penelitian terhadap ujicoba penggunaan IoT pada mendeteksi Kesehatan Mental. Dalam beberapa kasus, hasilnya masih belum sesuai dan diharapkan. Studi litelatur ini fokus menganalisis pada beberapa penelitian termuktahir mengenai penerapan IoT pada Kesehatan Mental. Tujuan utama adalah memungkinkan pembaca untuk memahami konsep dasar Kesehatan Mental dan merangsang penelitian lebih lanjut di Indonesia mengenai analisis Kesehatan Mental pada perangkat IoT.

Market Basket Analysis is an analysis of consumer behavior specifically from a certain group/group. Market Basket Analysis is generally used as a starting point for seeking knowledge from a data transaction when we do not know what specific pattern we are looking for. Market Basket Analysis in this study is applied to the search for patterns of purchasing groceries at grocery stores and then analyzed by season. This study aims to compare the Apriori, Apriori TID and FP-Growth methods in determining consumer transaction behavior and calculating the quantity of consumer transactions in several seasons based on data obtained from the Market Basket Analysis database. In the results of this study, it is known that FP-Growth has the best performance among the other two algorithms, but uses more memory than other algorithms. The Apriori-TID algorithm uses lighter and faster memory than the Apriori Algorithm
