Abstract

Malang city is a city that has a significant increase in population, which is around 50 thousands people in just period of 5 years. One of the reasons is because Malang city is a city of education, the reasons its called city of education is because in this City there are a lot of public university and private university that are quite popular, such as Universitas Brawijaya (UB), Universitas Islam Malang (Unisma), etc. This resulted many migrants from outside the area of Malang city study in Malang city. There are some things that might be the reasons why migrants choose Malang city, such as the Malang city have one of the best quality university in Indonesia. When becoming a migrant, the most needed thing is certainly a place to live in a long term, because of that the migrants need information on where to live in the form of boarding house or rent house to live in, we can get this kind of information trough social media like Twitter, but on Twitter there is still no category for this kind of information. By seeing this problem, we can use Classification technique to classified the information in the form of living quarters in the city of Malang. In this study Naive Bayes method is used as the classification method, and Information gain as the feature selection method. Before entering the classification process the weighting is done first using TF-IDF-CF method. This study uses 150 training data and 60 testing data. The highest accuracy value in this study are 71,66% using 33% of feature, using TF-IDF-ICF weighthing and, without using number feature.

Abstract

The data sending mechanism between a resource-constrained sensor and an Internet-of-Things middleware (IoTM) must be considered to enable remote and periodical data recording. Such recording is paramount in the context of human heart monitoring. In a previous study, Bluetooth was used in a health-data sending mechanism from sensor to smartphone. However, the solution introduced new problem that is silo. Meanwhile, the Bluetooth Low Energy (BLE) protocol is more compatible to the resource-constrained sensor and has safe radiation levels. Also, the smartwatch is popular for recording human heart rate. Then, the silo can be averted by applying event-driven IoTM. Thus, this research proposes a health data-sending mechanism from smartwatch to IoTM utilizing BLE by implementing BLE gateway on the IoTM. The health data is the smartwatch user's heart rate measurement. The health data are uploaded to a cloud server via IoTM's internet gateway device (IGD) for analyzing. The research's result is a functional health data-sending mechanism that satisfies the sensor's resource-constrained characteristic. The health data has a maximum size of 17 byte. The optimal distance between the smartwatch and the IoTM is 10 meters, with a maximum end-to-end delay of 3.7 seconds and a minimum Packets Reception Ratio of 96%.

Abstract

Letter has become a written communication media that is important to fulfill lots of organizations or companies needs. The current thought about organizing letters is that it needs high level of precision which is take too long to be done. This situation is similar to what happened in Faculty of Computer (FILKOM) University of Brawijaya. They have been using Microsoft Excel to manage all of the corresponding letters until this time. In this way, the distribution of letters has become less effective knowing that there is no integration between units/divisions. Oftentimes, the distributed letter is stopped because of some reasons. It could be that the receiver is not available at that time, or there is no information whether the letter has already been handled or not. These kinds of problems can be solved by developing a web-based letter management system where each unit is integrated to one another. In this way, the distributed letter and its monitoring can be easily done without considering place and time. Waterfall model process is used by the author in developing the software. In requirement engineering phase, there are found 33 functional requirements and 1 non-functional requirements. Based on the requirement engineering result, system is designed to be implemented in the next phases. The testings performed are unit testing, integration testing, and validation testing that result 100% valid in all test scenarios. And based on the compatibility testing, it is known that the system worked with no problems occurred in 73% of 11 versions of tested browsers.
