Abstract

Teaching and learning process are growing over time and technology behind it are growing too so that the process of learning with online media or often referred to as e-learning where provided media that can be accessed via the internet. This phenomenon is interesting to examine because some e-learning systems that exist today are not yet fully secure, in the sense that it is still easy to be disseminated without any copyright and not used wisely. The purpose of this research is to produce an application that can be used as a media for e-learning of streaming audio and video without storing the file on local cache device so that the file residing in e-learning media cannot be disseminated and be used wisely. As a research methodology using deductive qualitative method, data collective process is done by literature study, interview, and observation. After the data collected, will result e-learning software based on website and mobile that can be used to stream media files without downloading it. The result of this test and analyze shown that streaming with RTSP protocol is can be used into e-learning software with a limited users.

Abstract

In modern times, humans have been helped by many technological developments. One such field is the goods delivery field, called the Vehicle Routing Problem (VRP). Vehicle Routing Problem is a matter of where there is a freight fleet that has to deliver a certain amount of goods to various customers. The solution sought is the shortest route the fleet can take.,Hybrid Ant Colony Optimization (HACO)is an algorithm that is inspired from the foraging behaviour of ant species, that is one of the result of  development for Ant Colony Optimization. HACO has been published by Q. Ding et. al in 2012 to solve Vehicle Routing Problem with Time Windows. However, in that published journal, there were vagueness in some points like process time and memory usage. Therefore in this journal there is a need to review the performance of HACO to solve VRPTW, which will be done using unity. In this thesis is also discussed some development of HACO which are expected to fix and improve the result of HACO.

Abstract

HIMA or Himpunan Mahasiswa is a student union on the department’s level in a university. HIMAINFRA is the Student Union of the Department of Informatics and Business Information System of Petra Christian University. HIMAINFRA aims to address the needs of all students of the Department of Informatics and Business Information System of Petra Christian University in academic and non academic matters. One of the services of HIMAINFRA is to distribute announcements and upcoming events to the students.Nowadays, HIMAINFRA uses posters and social media, such as LINE and Instagram, to distribute the announcements and information to the students. However, due to some limitations on the social media, not all announcements and information from HIMAINFRA can be received by the students. Besides that, to register as an event participant or an event committee, the student still need to do it manually (i.e., paper-based).This Android-based HIMAINFRA application was developed to help HIMAINFRA distribute the announcements and information. This application also helps HIMAINFRA’s members on running a committee and enables the students of the Department of Informatics and Business Information System to register online as event participants or committees. This application leverages on Firebase Realtime Database and Firebase Cloud Messaging.

Abstract

There are many disturbance that may occur during the learning process, both internal and external disturbances. Internal disturbance that may occur is the inactivity of a microphone or speakers in the classroom, the phone that accidentally sounds from students or lecturers also become an internal disturbance that may occur. On the other hand, external disturbances that may occur in the classroom are noise or out-of-class activities or there is a vehicle noise disturbing the tranquility. Another problem is when students are left behind in material explanations. Many students are also reluctant to re-ask the lesson that is left to the teacher who then even ask his own friends rather than the lecturers, thus disrupting the concentration of other students.To resolve the issue, an application that replicates the SmartHear application is created. This application can help lecturers and students to improve the quality of understanding during the learning process. The SmartHear app can also help students to record ongoing streaming sessions.Testing is done by trying various Android devices to deliver streaming and receive streaming results. Each android device with the API above 19 already meets the standards in order to run the application but there are other factors such as the size of random access memory (RAM) and the type of processor. This application is also created with a version that will process voice input with generalized maximum a posteriori spectral amplitude (GMAPA) algorithm, but this algorithm can not be processed properly in Android devices due to the lack of computing capabilities that can be done in android devices.

Abstract

PT. Asri Indah adalah sebuah perusahaan yang bergerak di bidang produksi bahan bangunan gypsum. Setiap lis gypsum yang diproduksi memiliki jenis dan ukuran yang berbeda sehingga mengalami kesulitan dalam menentukan harga pokok produksinya (HPP). Pada bagian produksi juga memiliki masalah yaitu seringnya terjadi kesalahan dalam pertukaran data yang berujung pada miskomunikasi antara produksi dan gudang bahan baku dan kesalahan dalam penjadwalan produksi. Pembuatan laporan yang dibutuhkan perusahaan juga masih dilakukan secara manual. Oleh karena itu, berdasarkan masalah yang dipaparkan di atas, maka dibutuhkan sebuah sistem informasi (SI) yang mampu mengolah data-data dari proses produksi menjadi informasi berupa penentuan harga pokok produksi, penjadwalan produksi dan laporan yang dibutuhkan oleh perusahaan PT. Asri Indah Surabaya.Sistem ini akan dibuat berbasis website menggunakan bahasa pemrograman HTML, CSS, JavaScript, AJAX serta menggunakan database MySQL. Sistem Informasi akan dibagi menjadi 5 hak akses yaitu Admin, Produksi, Gudang Bahan Baku, Gudang Barang Jadi, dan Pimpinan.

Abstract

Server room is room which is store server, networking hardware, etc. A server room must have standard security which is can protect devices like temperature of server room, humidity server room, fire, access to the entry of people who are considered less responsible.Lack of control and monitoring of room temperature and humidity are common. This is due to lack of supervision or control of the staff or admin of the server room. If the temperature and humidity of the server room is uncontrolled then hardware inside the room can be broke or the performance of the server devices can be decrease. Often the security of the server room from the reach of less responsible people is also under-scrutiny. So sometimes there are people who can enter into the server room without knowing the intent and its purpose.The solution to this problem is to use a room monitoring application, which can be used to control and monitor temperature and humidity in the server room, so that the temperature and humidity of the server room can be maintained. This app can also prevent unauthenticated people from entering the server room.
