Utilization of Data Oriented Technology Stack in Unity Game Engine and Unity's Classic Technology to Develop Danmaku Game

Tantyo N. T., Med Irzal, Lipur Sugiyanta — Sun, 12 Nov 2023 16:25:52 +0700

Video games are relatively resource-intensive. Unlike most common apps, they require additional quality of their resources such as bigger RAM and faster processing speed due to the nature of unpredictability. Even now, one could say that despite the advancement in hardware technologies; a number of video games still demand better resources. To aid this issue, Unity Technologies has introduced a new technology called Data Oriented Technology Stack for their game engine; or DOTS. The DOTS technology is based on the Entity Component System architecture which is an adaptation of the data-oriented paradigm for engineering a software program or for a solution. But as of the time of writing this, the technology isn’t ready yet and considered unstable; so a game developer that wishes to use DOTS still need to use the classic technology of the engine. To display the usability and a degree of potential from Unity’s DOTS technology, this thesis will present a danmaku game development using both DOTS and the classic MonoBehaviour technology.

Factors Affecting Behavioral Intention of Delivery Drones During the COVID-19 Pandemic

Ari Hendarno, Med Irzal — Sun, 12 Nov 2023 17:00:20 +0700

Delivery of goods which is usually done by face to face is advised not to do. Physical distancing is recommended by World Health Organization (WHO). Physical distancing helps limit the spread of COVID-19 this means we keep a distance of at least 1m from each other and avoid spending time in crowded places or in groups (WHO, 2020). A possible alternative is to make deliveries using drones. It can keep the sender and receiver from seeing each other face to face. The final decision on using the drone delivery service rests with the customer. This will be closely related to customer's behavioral intention. This study aims to find out what factors influence behavioral intention to use drone delivery during the COVID-19 pandemic. The factors analyzed were function, cognition, hedonic motivation, incentive, social benefits, and health benefits. These factors are tested and analyzed which influences behavioral intention. The results obtained are function, cognition, and health benefits. The significance level in this study is 0.1 with a limit T-value of 1.29007.

Angga Arian, Ria Arafiah, Muhammad Eka Suryana — Sun, 12 Nov 2023 17:19:35 +0700

The animal that is currently being studied a lot is the cat, because there has been a lot of research related to this cat and it is easy to learn. This cat research also needs an expert or experts who can study this, especially cat diseases. This thesis research is aimed at the need for the public to know cat disease which is then applied in the form of an Android-based expert system application. Making this application of an expert system for recognizing cat diseases uses a method that is often used and studied by many people, namely the Naïve Bayes method. The purpose of making this cat disease recognition expert system is to help users, especially cat lovers, to get information about recognizing and treating their pets at an early stage when they have problems with their health so that they can recover faster from their illness. The results of the expert system research on the introduction of cat diseases, namely this application is used to determine the cat's disease suffered from the symptoms that have been described in the application and these symptoms are obtained directly from interviews from the two doctors (experts). The test also got good results, namely 100%.

Penentuan Tipe Attention Deficit Hyperactivity Disorder Menggunakan Metode Dempster Shafer

Saphira Maulidina Faturahman, Med Irzal, Ria Arafiah — Sun, 12 Nov 2023 17:31:42 +0700

Attention Hypercativity Disorder terdiri dari tiga tipe, yaitu Inatensi, Hiperaktif-Impulsif, dan gabungan Inatensi Hiperaktif-Impulsif. Periode anak usia dini hanya berlangsung pada saat anak dalam kandungan hingga usia dini, yaitu 0-6 tahun. Tidak semua orangtua yang memiliki kemampuan finansial untuk mendatangi psikolog anak atau psikiater anak, karena untuk melakukan konsultasi membutuhkan biaya yang tidak sedikit. Selain faktor biaya, faktor waktu juga mempengaruhi orangtua tidak bisa konsultasi kepada pakar, hal itu disebabkan oleh terbatasnya waktu praktek atau jauhnya lokasi anak dengan lokasi konsultasi. Dalam hal ini, selaku orangtua yang memakai jasa, orangtua membutuhkan pakar yang bisa memudahkan dalam mendiagnosa gangguan lebih dini. Teori Dempster-Shafer adalah representasi, kombinasi dan propogasi ketidakpastian, dimana teori ini memiliki beberapa karakteristik yang secara instuitif sesuai dengan cara berfikir seorang pakar, namun dasar matematika yang kuat. Secara umum teori Dempster-Shafer ditulis dalam suatu interval. Interval tersebut digunakan untuk mengkombinasikan potongan informasi yang terpisah dan mengkalkulasikan kemungkinan dari suatu peristiwa. Proses pengujian dilakukan dengan menggunakan bahasa pemrograman PHP dan database mysql. Rangkaian penelitian ini berhasil mengakuisisi data dari pakar mulai gejala sampai tipe ADHD. Representasi pengetahuan pada sistem ini dalam menentukan tipe ADHD berdasarkan gejala dari setiap tipe ADHD yang ditampilkan dalam bentuk memilih gejala yang dirasakan. Penelitian ini telah menerapkan metode dempster shafer untuk menentukan tipe ADHD serta memberikan hasil berupa keterangan tipe ADHD.

Design and Build a Mathematics Mobile Learning Application on Android-Based Geometry (Three Dimensional) Material at MA Islamiyah Darul Irfan Sawangan Depok

Mobile Learning is learning through mobile wireless technology that supports everyone to access information and learning materials from anywhere and anytime. Mobile Learning Based on the reason that learning can be done anywhere and anytime. Mobile Learning has a broad scope because it uses commercial cellular networks. In the process, the presentation of e-learning based on this Android mobile application can be more interactive. Information on learning materials and access to materials can be presented up-to-date and in real time. This thesis aims to design and build a mobile learning application for mathematics on android-based three-dimensional material to make it easier for teachers to deliver geometry learning materials about three dimensions and make it easier for students to understand three-dimensional learning materials. Mathematical mobile learning application on Android-based three-dimensional material which was developed using the spiral model software development life cycle method. This application is built using the CodeIgniter framework and the Java programming language. Users in this application open 2, namely teachers who can present material in the form of videos and provide exercises for students, students who can see video-based learning materials and exercises carried out by teachers as a refusal given by students in understanding the material presented by the teacher concerned.

Perancangan Sistem Informasi Praktik Kerja Lapangan Berbasis Website

Praktik Kerja Lapangan (PKL) merupakan mata kuliah yang wajib diambil oleh mahasiswa Ilmu Komputer UNJ. Mata kuliah yang terdiri atas 2 sks ini bertujuan untuk memberi bekal kepada mahasiswa agar mengetahui permasalahan di dunia kerja yang berkaitan dengan mata kuliah yang pernah diambil sebelumnya dan dapat membuat deskripsi teoritis dan analisis dari sudut pandang bidang studi yang bersangkutan serta memberikan atau menjelaskan alternatif pemecahannya dalam bentuk laporan untuk diseminarkan. Skripsi ini bertujuan untuk membangun suatu sistem informasi praktik kerja lapangan berbasis website yang dapat membantu Program Studi Ilmu Komputer Universitas Negeri Jakarta dalam melaksanakan pemantauan dan administrasi terkait praktik kerja lapangan. Sistem Informasi ini dikembangankan menggunakan metode pengembangan perangkat lunak SDLC dengan Model Spiral, framework Code Igniter untuk back-end dan framework Bootstrap untuk front-end. Pada akhir pengembangan dilakukan pengujian sistem menggunakan Black Box secara fungsional dan skala likert untuk menguji tingkat kelayakan sistem, dapat dikatakan bahwa Perancangan Sistem Informasi Praktik Kerja Lapangan berbais website telah berjalan dengan baik dan sesuai yang diharapkan dengan tingkat kelayakan sebesar 87,1% pada keseluruhan sistem.
