Abstract

E-vote system is a system to collect vote that involves electronic devices in order to improve the rate of voting practice, reduce the cost used, and improve the accuration in vote counting. Several researches utter that procedures which exist in current e-vote system is not enough to ensure data integrity, especially against an insider attack. Thus, this research is conducted to improve stored data integrity in data storage using permissioned blockchain where data processing and data storage are carried out in distributed manner. This research will produce an e-vote system which is integrated with permissioned blockchain using Hyperledger Fabric as the platform and Hyperledger Composer as a tool. To access the permissioned blockchain, user can utilize a node appropriate to his role in system. There are three roles in the system, that is Admin, Voter, and Operator. Application development for user's node will make use of Hyperledger Composer. Then, to know whether the system can actually protect data integrity in peer or not, some test cases will be conducted. The results of those cases show that e-vote system integrated with permissioned blockchain is capable to protect data integrity.

Abstract

The property business in Indonesia is one of the businesses that has experienced significant development. This is evidenced by the many new housing developments at competitive prices. Kupang City is the capital and administrative center of the Nusa Tenggara Timur (NTT) province, Indonesia. Based on data from the Central Statistics Agency of NTT Province, the increase in the population in NTT has increased by 2.07%. But in reality many prospective property buyers are still confused to buy a house by using a mortgage (KPR) because they do not know the amount of funds to be paid every month and also the difficulty of having to survey the state of the house one by one makes the prospective buyers overwhelmed to look for addresses from home sales agent. To solve this problem, the Land and Property Marketplace System is developed which is expected to facilitate potential buyers and investors in selecting, surveying and obtaining information related to the property to be purchased. The Land and Property Marketplace Systems provide the main features such as agent registration, property registration, KPR simulation, KPR info and also direct comment and chat features between potential buyers and property agents. The Land and Property Marketplace System will be implemented with the Laravel framework using the PHP programming language and JavaScript on the backend side and PhpMyAdmin as a database used to store data. This system produces 20 functional needs and 1 non-functional needs, and found 3 actors is agent, customer, and guest. The system tests using unit testing with the white box method and validation testing with the black box method obtained 3 unit tests and 27 validation tests with 100% valid results. Then the system complimented with compatibility testing using SortSite's software to request system robustness if requested in various web browsers and obtain 100% valid system results in various web browsers.

Abstract

Chronic Kidney Disease (CKD) is deadly disease and need high cost to do hemodialysis every week. CKD can happen because acute kidney disease for long time and not do any further treatment or change lifestyle to prevent CKD. So, people need to know is that potentially suffer CKD or not for early time. One of ways to know people suffer CKD is compare pattern with people that already suffer CKD. K-Nearest Neighbor is method that can to compare and classify data to nearest similarity of CKD's data. However, CKD has many feature that can use to classify people that suffer CKD. That feature can be people health data and lifestyle. That many feature must choose only most effective feature for classify CKD and discard the other feature. The feature selected can improve KNN to better classify CKD. KNN can know the better feature with try every combination feature. If KNN do that, it will need long time to find it. KNN need to improve efficiently and short way to know most effective feature for CKD. Bat Algorithm (BA) is method that can search solution that imitate behavior of bat. BA-KNN or combination BA and KNN proposed to solve the problem.
