Abstract

Information has become indispensable in this modern era, especially with the existence of various social media that support information update. Twitter as one of the most active social media is used to update information belonging to short text or short stories that have some difficulty when done classification, such as ambiguous word, the word contained in the test data never appear in the data train and so on. This research was conducted to determine the effect of using feature expansion or addition of word on short text in the result of classification. Prior to classification, the first data to be tested is added to the list of pre-made words as an external source or dictionary with specified limits. This limitation aims to determine the minimum value of the most optimal limit in generating the highest accuracy in the classification process. In the process of making external sources cosine similarity process is done to find the closeness between words. The result of this research is accurate showing effect of expansion of feature expansion in classification result, 83% accuracy in classification without feature expansion and increased to 87% on feature expansion with threshold value 0.9.

Abstract

PT Pembangkitan Jawa-Bali (PJB) Surabaya is a subsidiary of PT Perusahaan Listrik Negara (PLN) that worked in the provision of electrical energy of high quality, reliable and eco-friendly. One of the units contained in PT PJB is the Unit Bisnis Jasa Operation & Maintenance Luar Jawa-2 (UJLJ-2) which is tasked to conduct goods and services procurement activities on electrical assets in the generating unit. In carrying out its activities, UJLJ-2 is equipped with an information system to reconstruct procurement data from start to finish called Procurement Monitoring System (SIMOP). However, in the operation, there was found the constraint that users feel difficult when using SIMOP due to different user backgrounds and not yet able to adapt to the system, and therefore the evaluation of usability is needed to find out how easy the system can be used by the user. By using the method of Usability Testing with Nielsen model and based on three criteria of Efficiency, Error, and Satisfaction, the evaluation is done by testing the task scenario, interview, and post-Study System Usability Testing (PSSUQ) questionnaire to SIMOP users. From the result of evaluation of usability we got the value for Efficiency criteria equal to 58,5% that not high enough, value of Error criteria equal to 4,5% that means few errors, and value for Satisfaction criteria equal to 74,5% that means high enough.

Abstract

In the development of Wireless Sensor Network (WSN), it has an important role for human life. The need for a system to monitor the environment leads to the need for system that can survive under resource limited condition. Therefore it is necessary for mechanism or method that can overcome this problem. In the previous research has made a way of power savings made in software but in this study the author has done a hardware implementation instead. In this research, the authors have successfully integrated a method called wake up interrupt that utilizes the Real Time Clock (RTC) module to run low power mode in each sensor node that has been created. This sensor node consists of Arduino Pro Mini as a main processing module, NRF24L01 as a wireless communication module and RTC module that divided into two nodes which are receiver node and transmitter node. From the results of this research, the power saving mechanism is capable of saving power up to 81.25% of used current when the sensor node has entered the sleep mode.
