are carried out on the internet. Many platforms offer virtual transactions, such as motorcycle taxis, online marketplaces, and banking. For transacting on the internet, reliable data security is needed to maintain the security of user data from internet crimes (cybercrime). For cryptography learning to produce students who understand cryptography in-depth, this learning is carried out independently. One of the lessons to improve independent skills is a project approach. With project-based learning, students will be actively involved in completing projects given by the lecturer. To facilitate interaction and monitor projects completed by students, an LMS (Learning Management System) was created. The lecturer will later upload the student projects through the LMS, and if the student wants to work on the project, they can download it from the LMS.

Abstrak:†Kriptografi merupakan salah satu mata pelajaran yang penting untuk dipelajari karena isi bahasannya membahas tentang pengamanan data. Saat ini, keamanan data memiliki peran yang sangat penting, mengingat sebagian besar aktivitas transaksi dilakukan di internet. Banyak platform yang menawarkan transaksi virtual, seperti ojek online, pasar online dan perbankan. Dalam bertransaksi di internet dibutuhkan keamanan data yang handal untuk menjaga keamanan data pengguna dari kejahatan internet (cyber crime). Agar pembelajaran kriptografi menghasilkan mahasiswa yang memahami kriptografi secara mendalam, maka pembelajaran ini dilakukan secara mandiri. Salah satu pembelajaran untuk meningkatkan kemampuan mandiri adalah dengan pendekatan project. Dengan pembelajaran berbasis project, mahasiswa akan terlibat aktif menyelesaikan project yang diberikan dosen. Untuk memudahkan interaksi dan monitor project yang diselesaikan mahasiswa, maka dibuat LMS (Learning Manajement System). Setiap project mahasiswa nantinya akan di unggah oleh dosen melalui LMS dan mahasiswa bisa mengunguh project di LMS
Dengan menambahkan LMS dan pembelajaran yang berbasis project pada pembelajaran kriptografi menunjukkan hasil belajar yang lebih baik. Hal ini dapat dilihat pada hasil tinjauan dilangan dengan penyelesaian sebuah soal dan hasil ujian akhir mahasiswa.

t role in attracting and retaining application users. Therefore, this study has goal to compare the music steaming applications’ user experience of the Joox and Spotify by using User Experience Questionnaire (UEQ) method. There are 6 scales assessed by UEQ, including attractiveness, perspicuity, efficiency, dependability, stimulation, and novelty. Data was collected by distributing online questionnaires and obtained as many as 104 responses that could be processed. The results show that both applications have positive impressions which are indicated by the average value of each scale greater than 0.8. This indicates that these two applications are considered quite fun, effective, easy to understand, and innovative. However, the comparison’ results show that between Spotify and Joox is not significantly different, with Spotify scores slightly better than Joox.

f an Air Conditioner (AC) is needed for the coolness of a room. Many air conditioners in the office and educational environment make air conditioning health checks quite time and effort-consuming. To save time and effort in checking the health condition of air conditioners, then designed a device that can check the health of air conditioners by utilizing UHF RFID to identify each air conditioner. This device is divided into 2 parts, the first is an AC condition sending device that detects room temperature and current in the AC. Second, the receiver of the AC condition functions to find out the AC condition and sends the AC condition to mobile device. This experiment was carried out on 3 AC units. Each air conditioner is in a different room with a type of dividing wall made of glass and gypsum. The test results of this device are in a room with a length of 10 meters, the device can detect AC conditions. The air conditioner is in a different room with glass and gypsum walls, the device can still read the condition of the air conditioner.

Abstrak: Kondisi ruangan yang nyaman merupakan salah satu faktor yang dapat mempengaruhi keberhasilan suatu pekerjaan dan proses pembelajaran. Untuk membuat ruangan tetap nyaman, suhu di dalamnya harus sejuk. Menjaga kesehatan Air Conditioner (AC) sangat dibutuhkan untuk kesejukan sebuah ruangan. Banyaknya AC di lingkungan kantor dan pendidikan membuat pemeriksaan kesehatan AC cukup banyak memakan waktu dan tenaga. Untuk menghemat waktu dan tenaga dalam melakukan pemeriksaan kondisi kesehatan AC, maka dirancang sebuah alat yang dapat melakukan pemeriksaan kesehatan AC dengan memanfaatkan UHF RFID untuk mengidentifikasi masing-masing AC. Alat ini terbagi menjadi 2 bagian, yang pertama adalah alat pengirim kondisi AC yang mendeteksi suhu ruangan dan arus dalam AC. Kedua, penerima kondisi AC yang berfungsi untuk mengetahui kondisi AC dan mengirimkan kondisi AC tersebut ke perangkat seluler admin. Percobaan ini dilakukan pada 3 buah AC. Setiap AC berada di ruangan yang berbeda dengan tipe dinding pemisah yang terbuat dari kaca dan gipsum. Hasil pengujian perangkat ini berada di dalam ruangan dengan panjang 10 meter, perangkat dapat mendeteksi kondisi AC. Pada AC yang berada di ruangan yang berbeda dengan kaca dan dinding gipsum, perangkat tetap dapat membaca kondisi AC tersebut.

with different weight values. The number of applicants for the scholarship recipients is enormous; a Decision Support System (DSS) is needed to help the selection process be more accessible and faster and reduce errors in determining scholarship recipients. The data collection method uses interviews, observations, and literature with the waterfall's system development method. The calculation of the criteria used in developing this system is the Simple Additive Weighting (SAW) method. Comparing the final results between manual and system analyses shows that the equation is close to 100%. Still, the final results may be different because manual calculations use raw values, while system calculations use the Simple Additive Weighting (SAW) method, which compares alternatives.
