Abstract

Wireless Sensor Network (WSN) merupakan infrakstruktur jaringan yang dapat memudahkan dalam pemantauan pada sebuah objek. Penelitian ini menggunakan routing protocol AODV, protocol AODV memudahkan jaringan wireless sensor network dalam melakukan penentuan jalur pengiriman data secara mandiri. Protocol AODV memiliki kelemahan didalam pengiriman data. Blackhole attack dilakukan dengan mengirimkan paket RREP palsu ke dalam jaringan. Tujuannya untuk melakukan drop packet pada setiap pengiriman data antara source node dan destination node. Algoritma probabilitas sequence number merupakan mekanisme yang dapat digunakan untuk melakukan mitigasi blackhole attack pada jaringan wireless sensor network yang menggunakan protocol AODV. Mekanisme algoritma probabilitas sequence number dilakukan dengan cara memfilter sequence number sehingga hanya packet RREP asli yang dapat diterima oleh source node. Sequence number merupakan salah satu parameter yang terdapat pada paket RREQ dan RREP. Nilai parameter sequence number akan semakin bertambah setiap terdapat perubahan jalur yang digunakan. Hasil penelitian ini, algoritma probabilitas sequence number dapat memitigasi blackhole attack sebanyak 8 node dari 25 malicious node. Rata-rata packet loss sebesar 27,72 %. Rata-rata end to end delay sebesar 129.752 ms. Rata-rata packet delivery ratio sebesar 72,30 %.

Abstract

A common solution for myopia sufferers is to wear glasses. However, glasses are not for curing vision, but they only help sufferers to see more clearly. In 1920 Dr. William Horatio Bates invented a practical and free method called the Bates method, this method can be done by everyone to cure minus eye without having to use tools. The Bates method is implemented into an application called Bates EyeCare using virtual reality technology. Bates EyeCare simulates eye muscle training in a virtual world by using objects in that world as a training reference. By utilizing the personal extreme programming development method aimed at developing fast and concise individual applications, 2 iterations with 1 iteration focused on developing eye sports methods in the virtual world using Unity3d with real processing time of 30 hours 7 minutes, faster 5 7 hours from the estimated development time, while the development in iteration 2 focuses on implementing the unity module from the results of iteration 1 on Android Studio so that the virtual world can be used on the Android mobile platform with real processing time is 20 hours 40 minutes, 20 minutes faster than the estimate development time. User acceptance testing was conducted on 4 respondents with a final score of 5,582, which stated that the overall user was of the opinion Agree that the system has succeeded in meeting the needs of the user.

Abstract

The authentication system using the Long Range (LoRa) module with the Wireless Sensor Network (WSN) mechanism still has problems. The problem lies in the security side of sending authentication data. The authentication that is carried out only matches the ID number as the identity of the sensor node that will communicate to the gateway node. This can cause unauthorized parties to easily break into the system. The Fiege-Fiat-Shamir (FFS) Identification Scheme authentication method is one method that implements the Zero-Knowledge Proof (ZKP) mechanism. The ZKP mechanism is an authentication method used to prove verifier, without providing confidential information or providing a way for other people to find out the confidential information. The authentication is done by matching the evidence generated from the key pair using the FFS identification scheme method. This research resulted in the FFS identification scheme authentication system being successfully implemented in the WSN mechanism using the LoRa module. Attacks carried out by using fake nodes to communicate and replay attacks with duplication of authentication data have been successfully overcome using an FFS identification scheme mechanism.The authentication validation level is 100% which is calculated using confusion matrix.

Abstract

Social media is a platform for people to sharing their views on certain things or events. One of the things discussed on social media is the Job Creation Law (UU Cipta Kerja). The Job Creation Law is a law that simplifies regulations related to licensing activities in starting a business and investing with the aim of increasing Indonesia's economic growth. Twitter is a social media where many users share their opinions regarding the Job Creation Law. Therefore, Twitter can be a source for analyzing user opinions regarding the Job Creation Law. This research was conducted to analyze the sentiment on tweets (a term for content uploaded to Twitter) regarding the Job Creation Law by classifying tweets into two categories, positive and negative sentiment. The classification process is done by implementing an Artificial Neural Network (ANN) trained by Backpropagation algorithm and term weighting using Term Frequency-Inverse Document Frequency (TF-IDF) method into Python. There are several stages in this study, there are data scrapping, data labeling, preprocessing, term weighting, training, testing, and performance evaluation. The best performance obtained by the ANN is 95% accuracy, 98% precision, 92.4% recall, and 95.1% f-measure. This value was obtained when the ANN trained with 1500 epochs, 1 hidden layer with 50 hidden nodes, and 0.2 learning rate

Abstract

Balai Besar Pelatihan Peternakan Batu is one of the technical implementation units (UPT) in the field of training under the Indonesian Ministry of Agriculture. Based on the results of the initial survey and the results of an interview with one of the employees there, BBPP Batu does not yet have a special information system for dairy cows in the area. Currently, the dairy cattle reproduction management process there is still using the recording process using a reproduction card that is written manually. These reproduction cards are sometimes borrowed by trainees and not returned. The fact stated by Dollar (2014) proves that there is an improvement in reproductive performance as long as there is a good reproductive management system. In overcoming the above problems, a solution was made in the form of a dairy cattle management information system which was built using the SDLC Prototyping method. At the analysis and design stage, a model is built that can facilitate communication between developers and stakeholders in order to find the best solution in the form of a web and Android-based information system. The models used in the analysis and design stages include use cases, use case scenarios, sequence diagrams, class diagrams, and relational models. The system that has been built will be tested using BlackBox testing, compatibility testing, and user-acceptance testing. Blackbox testing produces valid results in all tests. The results of Compatibility testing on web applications using SortSite5 is that all the browser that has been tested can run the reproduction management information system with some major and minor problems. For android applications, applications can run on Android API 19 (KitKat) and above. Then on UAT testing of actors and stakeholders, the resulting value of 100% acceptance of the system that was built indicates that the system can be accepted by stakeholders.

Abstract

Maintaining lineage for Muslims is important to avoiding certain sins. Digital bloodline recording media will help Muslims in remembering their bloodlines. One application that is already available is familysearch.org, developed by the FamilySearch and FamilySearch Tree organizations for mobile applications. But it is unknown whether this application can meet the needs of Muslims or not. Because of that, an usability evaluation was conducted on the applications that were available to see whether the application was able to meet the needs of Muslims or not. Data was obtained by testing the scenario to find usability problems for 5 participants by performing 28 tasks. The findings are grouped by thematic methods and it is found that the application still lacks the features needed for nasab for Muslims, the lack of instructions for use, the use of foreign languages, features adding information lacking the default category, a display that is less user-friendly for ordinary users, and general use will difficult for ordinary users. Recommendations given based on the findings include: the addition of complete information for Muslims regarding the passage, the addition of clearer instructions, the use of Indonesian, simplifying the appearance, and the category of adding more varied information.
