Sim Card Alarm for Android Smartphone Rikip Ginanjar; Ridho Utomo
ULTIMA InfoSys Vol 7 No 1 (2016): UltimaInfoSys :Jurnal Ilmu Sistem Informasi
Publisher : Universitas Multimedia Nusantara

Since the first Android smartphones were released, many applications have been developed until today. One of them is security application. Security applications consist of several types of applications such as Antivirus, SIM Card Change Alarm, and Applocker. SIM Card Changed Alarm is a security application that has capability to monitor SIM Card change in Android smartphones. Although there are many SIM Card Change Alarm applications which are available in Google Playstore, there are many people who are not satisfied with this applications. It happens due to them only sends the SMS alert to the owner without locking the phone to prevent other people using it. The outcome of this research will have the same feature as SIM Card Change Alarm but with additional features such as locking the smartphone if the SIM Card has been changed, locking and unlocking remotely using SMS, triggering loud alarm, and calling-back to owner when the smartphone has been lost or stolen. The outcome expected for the Prifone Application is a userfriendly application which could be used by many people around the world and also is able to secure Android smartphones.

Abstract— In recent years, micro-blogs on the Internet have become a popular way of expressing feelings, thoughts, and even communicating opinions about products and services that are common among its users. Collecting user opinions can be an expensive and time-consuming task using conventional methods such as surveys. The sentiment analysis of the customer opinions makes it easier for businesses to understand their competitive value in a changing market and to understand their customer views about their products and services. In this research, Lexicon-Based approach especially AFINN lexicon is implemented to classify user twitter sentiment, throughout which, twitter Micro-blogs data has been collected, pre-processed analyzed, and classified. The results of this research is an android application that could classify users' perspective via tweets into positive and negative, which is represented in a pie chart for Monthly report. Index Terms— Sentiment Analysis, Brand Analysis, Twitter, Android Application

In relation to the dissemination of information, the Internet is one of the fastest media to do so. The internet’s presence is growing very swiftly and rapidly, so it has become recognized by people from all walks of life. For that, the people need the appropriate way to maintain effectiveness in the use of the Internet. The following paper describes a study of the distribution of the cache, which is performed by the squid proxy server by creating a storage network design on Linux. Cache documents that are stored in the proxy server will be distributed to another over a network storage server. The process of caching on the proxy server is using the Least Recently Used (LRU) Algorithm. This research was carried out by developing the existing method of caching server process, then it is to be added a unit as a backup storage device for the data that must be erased because of the replacement policy applied to the squid proxy server. This study is looking at how the hit ratio and byte hit ratio after adding the storage server compared to not having a storage server. At the end of this research, it is concluded that the distributed cache processes a hit ratio and byte hit ratio higher than the cache on the current proxy server.

An Algorithm to construct nondominated k-coteries Rikip Ginanjar; Nur Hadisukmana

One of the solution in solving k mutual exclusion problem is the concept of k-coterie. A k-coterie under a set S is a set of subsets of S or quorums such that any k + 1 quorums, there are at least two quorums intersect each other. The k mutual exclusion problern is the problem of managing processes in such a way that at most k processes can enter their critical sections simultaneously. Nondominated k-coteries are more resilient to network and site failures than doninated k-coteries; that is the availability and reliability of a distributed system is better if nondominated k-coteries are used. Algorithms to construct k-coteries have been proposed, unfortunately they have some restrictions, especially in constructing nondominated k-coteries. The restrictions are due to the combination of N, the number of nodes in a distributed system, and k, the number of processes allowed to enter their critical sections simultaneously. To solve this problem, this paper proposes an algorithm to construct nondominated k-coteries for all combination of N and k.

THE IMPLEMENTATION OF FUZZY-TSUKAMOTO METHOD IN MAKING THE BEST DECISION TO BUY A SMARTPHONE Adwitya Rai Paramaartha; Rikip Ginanjar
IT for Society Vol 5, No 1 (2020)
Publisher : President University

Smartphone is one of the most important things for people nowadays. The increasing number of products as well as the amount information carried by each brand of smartphone can overload, there are many things to consider before buying a smartphone. Fuzzy logic is a form of many- valued logic in which the truth values of variables may be any real number between 0 and 1. Fuzzy logic is one method to analyze system containing uncertainty. This study aims to use fuzzy logic in helping people make decisions on buying the most suitable smartphone for them by producing an output value that can help the user to determine which smartphone will be purchased based on user’s ideal criteria of a smartphone.

Image Processing with Virtual Pencil and Virtual Mouse using Webcam Recognition for Drawing Rikip Ginanjar; Sijoatmodjo Ivan Carnelius
IT for Society Vol 1, No 1 (2016)
Publisher : President University

Recently, people use physical mouse to control the computer. Virtual Vpaint can be a new innovation to change the physical mouse to virtual mouse, then the users can minimize the cost of hardware consumption and damages. Having virtual mouse, users can control the computer only through webcam to do a lot of things such as drawing, editing images, mouse control, and others. Virtual VPaint application will discuss the development of Computer Vision for drawing an object in Windows form application by using virtual mouse. This application can perform common image editor such as blurring, gray scaling, and negating images. Users can control mouse pointer through the webcam by using object mover which has specific color, then can draw an object on canvas by using virtual pencil.

Class Reservation Application Rikip Ginanjar; Alvin Halim

Publisher : President University

Many student do class reservation for their own problem in the class either the lecturer or the student itself that do the reservation. In president university class reservation become one of the important system that exist in the university organization system to service of unanticipated extra schedule for the sake of class session. No wonder in one day so many student do the class reservation but wasting time because of complicated process of the reservation and also manual process that annoying especially for student. The university have computerized system for everything process in the university but not this simple one yet important. Many student always wasting time for only booking one class room that disturbing their activity because of the manual paper administration. The academic still use paper and find manually when they want to search empty room or checking room of some lecturer, because of this there happen so many times of miss information and communication that caused by negligance of the staff. We cannot hope them to do everything perfect because human can do some wrong too because of imperfectness that is why we need another solution for this to solve the problem.

Rubik’s Snake Simulator For PC Rikip Ginanjar; Natasha Janice
IT for Society Vol 3, No 01 (2018)
Publisher : President University

Rubik’s Snake is a toy that can be played by people with almost all ages. It is usually formed of 24 edges of right isosceles triangular prisms that are connected with spring bolts so that each edges can be rotated in some way to form a shape. Rubik’s Snake is a tool to test an idea of shape in space. This research will develop a 3D Rubik’s Snake simulator for PC with “Snix” as the name of the application. The simulator is expected to imitate a real Rubik’s Snake behavior that its edge can be rotated in some way to form shapes by implementing existing 3D computer graphics algorithms
