Abstract

Alumnus is someone who has graduated from high school or college and has an important role in showing image and quality, because the alumni association forum is not just a forum for friendship between alumni, but also a forum for discussion and communication in an effort to advance higher education. Until now, alumni of the National University (UNAS) integrate and communicate only through social networks such as WhatsApp and Facebook, so with this web-based internet facility, alumni can utilize and facilitate communication between alumni. This web-based social network is designed not only to connect alumni from the National University (UNAS) but can establish relationships between National University lecturers (UNAS) and can exchange information in various types such as job vacancies, training, professional certification, campus environment activities and information others that are useful for alumni and lecturers of the National University (UNAS). This site was created by first starting the system design using UML then proceed with the creation of a user interface and using the PHP and MySQL programming languages as database management. This site still has some shortcomings both in terms of features and security

Abstract

The queue of the most unpleasant activities for almost everyone in the world, a queue which means waiting for their turn to get service from a facility, such as Vespa motorcycle users who want to get service to repair their vehicles in the garage easily and quickly. Repairs are carried out ranging from minor maintenance to heavy maintenance such as dismounting the engine. The irregularity of existing service queues at Vespa motorcycle workshops makes consumers feel uncomfortable and disadvantaged. Therefore it requires an easy and regular Vespa motorcycle queue service. For this we need a system that can manage the queue service process for users. The method used to regulate services is Multi Channel Single Phase, namely there are two or more service system entry lanes and there is only one service facility in each lane. This method was chosen because it is able to set the queue, speed up the work process and shorten the waiting time for customer service.

Abstract

General elections are basically still carried out conventionally, namely by using paper media in voting. This will lead to weaknesses in the calculation of votes such as a waste of money and time. This study aims to develop a website-based e-voting information system in the general election for the chairman of the RW which is expected to minimize the weaknesses of conventional elections. This system was developed to make the voting process more efficient and easy to use. This application is designed using the PHP programming language and MySQL database, using the waterfall method. By doing black box testing, it is hoped that the e-voting system can run well functionally without any error, and dummy variable testing to determine the influence of voters in selecting candidates based on graduation rate

Abstract

Disebabkan cepatnya perkembangan teknologi yang terjadi, secara tidak langsung mempengaruhi banyak bidang, salah satunya dalam bidang pendidikan. Untuk membuat sistem pembelajaran menjadi lebih interaktif, dibuatlah sebuah aplikasi dengan mengimplementasikan teknologi  Mixed Reality (MR), yang merupakan hasil kombinasi Virtual Reality (VR) dengan Augmented Reality (AR). Penelitian ini mengimplementasikan teknologi Mixed Reality untuk media edukasi tentang jenis serta karakteristik bioma berbasis android yang memanfaatkan teknologi 3D sebagai objek pembelajarannya. Pengguna dapat berinteraksi dengan objek virtual, dan untuk memunculkan objek virtual dibutuhkan sebuah marker sebagai penanda dari objek virtual.  Algoritma FAST Corner Detection akan memindai marker untuk menentukan titik tengah gambar pada marker. Agar mendapatkan hasil yang lebih nyata dan interaktif digunakan metode Occlusion Detection, sehingga objek virtual dapat berinteraksi langsung dengan pengguna aplikasi. Aplikasi telah diuji pada perangkat dengan versi sistem operasi android yang berbeda-beda, yaitu Nougat (7.0) hingga R (11.0) dimana hasil pengujian jarak terhadap marker bervariasi, mulai dari jarak terdekat sebesar 10 cm hingga terjauhnya yaitu 240 cm hingga 300 cm. Juga hasil pengujian sudut kemiringan terhadap marker, batas maksimal sudut kemiringan marker dapat dipindai adalah sebesar 80°. Waktu respon Mixed Raeality pun diuji dengan cara menghitung lama waktu munculnya objek virtual saat pertama kali kamera memindai marker, yang menghasilkan waktu 0,5 detik.

Abstract

English is a language that is widely used in various countries in the world. This makes english an international language and also must be studied in schools or even universities. In english, the verb used will be different at different times, places, and also events or it can be called a change in the verb (tense). So, learning and mastering tenses in english is the basis for learning or mastering english. This study aims to design and build an Android-based learning media for english tenses. The design applies a form of english tense quiz using the Fisher-Yates algorithm, which is a randomization algorithm that can randomize the order of the quiz questions so that the order of the quiz questions is not always the same and there are no repeated quizzes. The expected results will later become a learning medium for people who want to learn or master english and can understand the tenses in english.

Abstract

The emergence of a habit in Indonesia and even the world, namely the use of used clothes (thrifting) became the idea for this research. This new habit is known to be able to reduce the production of textile waste in the world. The purpose of this study was to obtain analysis results that affect the use of new clothes (fast fashion) on the use of used clothes (thrifting). Using the K-means Clustering method and using several parameters, including age, quality, price, and sustainability or awareness. The method of collecting data is through a questionnaire and the research material is the buyers found in the online store Instagram (thriftboys.id). From the results of the clustering process that researchers have done using the K-means algorithm with manual calculations and rapidminer applications, the conclusions consist of; 1) In clusters 1 and 2 the age factor shifting from fast fashion to thhirft is 23 years, while in cluster 3 it is 25 years, 2) In the three clusters the average income that shifts from fast fashion to thhirf is group 3 or the range of 200000 -500000, 3) In the third cluster, people switch from fast fashion to thrift because of the good quality of goods, and 4) In clusters 2 and 3 more people are aware of textile waste for the world. Meanwhile, cluster 1 has the same number of conscious and unconscious waste.
