Abstract

A Zoo is a green open space that used to maintain welfare and exhibit animals for the public. Visitors who come to the zoo reach thousands of people a day and some of them are families who want to have recreation. The enthusiasm of visitors can be seen from visitors who want to give food to animals even though it is prohibited because it is dangerous and the animals have a predetermined diet. This study aims to make a vending machine in the form of purchasing tickets for feeding animals at the zoo with the working principle of a vending machine that implements finite state automata. The method used in this study consists of five stages, the first stage is problem identification, the second stage is system design using UML, the third stage is FSA design using state diagrams, the fourth stage is FSA testing using JFLAP, and the last stage is design of vending machine. The conclusion obtained from this study is that the application of the FSA concept to the pet food ticket vending machine can make transactions as many as 6 animal feeding schedules, this can be useful in adding services to the zoo.

Abstract

SMP Muhammadiyah Boarding School is a boarding school where students are required to live in a dormitory that has been provided. In addition to students, there are coaches whose job is to guide students after their teaching and learning activities are completed. In carrying out their activities in addition to guiding students, coaches really need an internet network connection to meet their needs and interests in finding things needed on the internet. In order to avoid problems in using the internet network from an ISP, it is necessary to have bandwidth management that can regulate the speed of internet connections so that it is more equitable in the distribution of internet bandwidth. If a LAN network without bandwidth usage management may often occur bandwidth struggles between client 1 and other clients. LAN (Local Area Network) is a computer network that is connected to a computer server using a certain topology, usually used in the area of one building or area not more than one km away [4]. With the problems as above, the authors conducted research and made a QoS Design and Implementation in Mikrotik Using the HTB Method (Case Study of SMP MBS AL KARIMAH). The author has analyzed that the topology used in SMP MBS AL KARIMAH is a Star topology with 1 Telkom ISP modem which is directly connected to the switch and from the switch to the client. This design is done by using a Mikrotik Router and a Winbox application for a remote Mikrotik router. Mikrotik is a Linux base operating system designed specifically for networking purposes [13]. In addition, MikroTik Router has several features such as authentication, authorization, client accounts, routing, mpls, Queues, firewalls, IP Telephony which allows Voice over IP (VoIP) [15].

Abstract

Opinion is an important part of decision making, so it takes the ability to get information from opinions. Sentiment Analysis is a branch of science from Text mining that can be used for opinion analysis in the form of text to classify opinions into 3 types of opinions, namely positive opinions, neutral opinions and negative opinions. Support Vector Machine (SVM) is one method that is widely applied for text mining because it is able to show good performance (Styawati and Mustofa, 2019). SVM works with a learning system that uses a hypothetical space in the form of linear functions in a high-dimensional feature space. Maximum Entropy is a probabilistic classification algorithm that belongs to the class of exponential models, which is based on the principle of Maximum Entropy. Maximum Entropy can be used to solve text classification problems such as Language detection, topic classification, and sentiment analysis. Sentiment analysis was tested using the Support Vector Machine (SVM) and Maximum Entropy methods to test the accuracy of each method in analyzing the sentiments of college alumni opinions. from the test results show Maximum Entropy has a better level of accuracy with the results of 95.45%

Abstract

The Sagrado Coração de Jesus Foundation is a formal educational institution that manages 58 Catholic schools in the Maliana Diocese of Timor Leste. In dealing with the payment of fees, Catholic schools under the Sagrado Coração de Jesus Foundation still use books to record payment transactions. These transactions must be carried out at the foundation, and it takes a long time to record transactions in the book so that it becomes a problem faced by the foundation, schools, and parents of students. A web-based school tuition payment application is needed by the Sagrado Coração de Jesus Foundation to handle the school's tuition payment activities on behalf. The use of website media makes it easier for parents to show proof of payment without having to come to the foundation. Applications that are built can also speed up the process of recording the payment of contributions by foundation employees. Based on the research results, the Web-based application for payment of tuition fees for Catholic schools at the Sagrado Coração de Jesus Foundation makes it easier for parents and foundations to make payment transactions more efficiently and quickly.

Abstract

Our research is the adoption of mutual authentication techniques on smart cards for Digital Rights Management (DRM) which is applied using network protocol engineering. We adopted the protocol engineering from the mutual authentication technique owned by the Mifare Desfire smart card. The tests carried out in our research are testing the security aspects of authentication and data confidentiality. Our authentication test is done by changing the client and server master keys that determine the success of authentication. Meanwhile, data confidentiality testing is carried out by tapping data sent from the client to the DRM server. When authentication by the client and server fails, the software is declared invalid and vice versa. The result of our research is the successful implementation of the adoption of the smart card's mutual authentication technique for application protection in DRM including authentication and encryption functions.
