Abstract

At this time, technological development is something we cannot avoid in this life, because technological progress will be consistent with the advancement of science. The whiteboard is one of the objects whose existence is very important in the teaching and learning process, a classroom as an important tool for writing learning materials. Android is a comprehensive open source platform designed for mobile devices. It is comprehensive because Android provides all the tools and a complete framework for developing applications on a mobile device. The Android system used a database to store important information needed to keep it even when the device is turned off. 3D printing or also known as Additive Layer Manufacturing is the process of making 3-dimensional solid objects or any shape from a digital model. This tool will be created using a technology whiteboard from which consists of hardware, namely Arduino Uno R3 and Expansion Board A4988. The way it works is almost the same as a laser printer with the technique of making objects from a number of layers, each of which is printed on top of each other. To solve this problem, we need a mechanical device that can work automatically and programmed so that it replaces the teacher's task in writing on the whiteboard.

Abstract

Seringkali masalah keamanan aplikasi terabaikan justru setelah semua peralatan dan infrastruktur pengaman telah terpasang. Bahkan pentingnya pengamanan baru disadari setelah terjadi bencana. Kerugian sebuah institusi/organisasi yang diakibatkan dari sebuah serangan terhadap sistem aplikasi sangatlah besar, tetapi hal ini sangat sukar dideteksi, karena secara umum tidak akan diakui dengan berbagai alasan. Tanpa pengamanan sistem aplikasi yang baik, penerapan teknologi sehebat apapun akan sangat membahayakan institusi/organisasi itu sendiri. Nilai informasi yang begitu penting dan strategis mengakibatkan serangan dan ancaman terhadap aplikasi dan arus informasi semakin meningkat. Kebutuhan keamanan sistem aplikasi timbul dari kebutuhan untuk melindungi data. Pertama, dari kehilangan dan kerusakan data. Kedua, adanya pihak yang tidak diijinkan hendak mengakses atau mengubah data. Rancangan arsitektur Aplikasi Dapodik yang dihasilkan dibatasi yaitu hanya pada aplikasi Dapodik berbasis web yang diterapkan secara offline dan online yang terkoneksi dengan internet. Pengujian keamanan aplikasi Dapodik menggunakan penetration testing dan SQL Injection. Berdasarkan hasil pengujian keamanan, dapat dinyatakan bahwa tingkat ancaman terhadap web server dan aplikasi Dapodik berada pada level aman. Hal tersebut menunjukkan bahwa tidak ada celah yang memungkinkan terjadinya ancaman dan akses ilegal yang berpotensi merusak sistem.

Abstract

Seiring dengan berkembangnya ilmu pengetahuan dan teknologi yang sangat pesat saat ini, telah berpengaruh pada kehidupan manusia. salah satu perkembangan teknologi yang pesat terlihat pada bidang Internet of Thing (IoT). Sumberdaya air merupakan salah satu unsur penting untuk keberlanjutan kehidupan makhluk hidup terutama manusia. Keberadaan air dapat berperan multiguna, dapat digunakan sebagai air minum, mandi, mencuci, mengairi lahan pertanian, pendukung pelaksanaan ibadah, dan perekonomian. Pengelolaan air bersih juga merupakan upaya pendayagunaan sumberdaya air dengan upaya mendistribusikanya kepada masyarakat. PDAM atau perusahaan daerah air minum merupakan salah satu unit usaha milik daerah yang bergerak dalam distribusi air bersih bagi masyarakat. Proses pengembangan sistem seringkali menggunakan pendekatan prototipe (prototyping). Purwarupa monitoring tagihan air Berbasis Internet Of things digunakan oleh seorang admin petugas PDAM untuk dapat memonitoring pendistribusian air, menghitung tagihan air, dan mengontrol penggunaan air apabila ada pelangggan yang belum membayar tagihan penggunaan air

Abstract

Campus introduction media in general still use billboards and brochures or advertisements, therefore the use of Virtual Reality technology is very good to use. Optimizing the application of this technology is made to build an interactive application that can visualize the facilities and infrastructure at University Majalengka in the form of 360 images and videos to make it easier for users to digitally view the facilities and infrastructure of the University Majalengka Campus. The method used in this research is MDLC (Multimedia Development Life Cycle). This method can optimize the manufacturing process and application of technology used in a smartphone media that is integrated with other media or 3D media. MDLC rule pattern itself by prioritizing interactive rests on the user. This application was built using the C # programming language with Unity 3D software. The final result of this research is the creation of a virtual tour application of the University Majalengka Campus which can be used by users to view interactive digital facilities and infrastructure on campus with a 360 degree angle using a smartphone that has a Gyroscope sensor which can be integrated with the paired virtual reality technology. into virtual reality glasses.

Abstract

Twitter is often used to express opinions about a topic or issue that is trending. In the early 2020 period in Indonesia, Twitter was enlivened by the issue of the COVID-19 virus caused by SARS-CoV-2. Many Twitter users have expressed their views on the COVID-19 issue, which has attracted the attention of several parties to be used as a reference in making new decisions or policies. Therefore, it is necessary to do a sentiment analysis to determine the polarity of the sentiments that are in the contents of the tweets. This study uses the Naïve Bayes Classifier (NBC) and Support Vector Machine (SVM) methods. with a total dataset of 1652 tweets. From the results of classification using the NBC method, the classification accuracy value is 78.3%. While the accuracy value obtained by the SVM method is 81.6%. While the results of the accuracy test using the Cross Validation method with 10 K-Fold CV results in an average accuracy value of the NBC method of 69.8% and an average accuracy value of the SVM method of 74.4%. It can be concluded that the SVM method is proven to have a higher accuracy value than the NBC method.

Abstract

Currently the development of technology is very rapid and has a role to help every human activity. One of the results of technological developments is radio frequency-based technology, RFID (Radio Frequency Identification). Utilization of RFID used on electronic identity cards (e-KTP) is a resident identity card equipped with a chip which is the official identity of the population as proof of self issued by the implementing agency. The administrative service process in most villages still uses conventional methods, one of which is Balida village. The process of administrative services such as making letters, within a week many people apply. so that public dissatisfaction with services arises, causing crowds, considering the covid-19 pandemic has entered Indonesia, people are required to comply with health protocols and avoid crowds. Therefore, the author initiated a system design to serve administrative services in the village of Balida to comply with the health protocol. The programming used for this application is PHP and uses the Laravel framework and MySQL as the database. The purpose of this study is to design an application for administrative services in Balinese villages that is integrated with e-KTP. The development method used is RUP. The result of the application of this administrative service application is that people who have an e-KTP can use it for letter administration.
