Abstract

A mobile application called Ruang Guru is one of the well-known E-learning applications in Indonesia which has the highest number of downloads; however, the large branding turns out to be inversely proportional to the quality or usability level provided. This study aims to find problems in the application of Ruang Guru which deeply interfere with the usability level by the experts. The method used was Heuristic Evaluation with the principle of E-learning, this heuristic method specifically used to evaluate E-learning, because in this method the principles used were 15 principles that include instructional content of learning. Based on the results of the study, 28 problems were found in 10 of the 15 heuristic principles of E-learning. 3 heuristic principles had the most number of problems with 5 problems, namely H1 (Visibility of System Status), H4 (Consistency and Standards), and H7 (Aesthetic). And the heuristic with the highest average severity rating is H5 (Error prevention). From the problems found, this study provided 28 recommendations for improvement. These improvement recommendations were divided into 3 types of improvements namely user interface design improvements, system and security improvements, and user training.

Abstract

FILKOM APPS is the system that support in FILKOM academic service, include in thesis. But in reality, there are problems in implementation, so it will make some troubles for the student as the users of this service. The problem is one with others student can't get verification from academic after the student upload their proposal at the same time. The other problem is student can't get letter of assignment in the same time with the other student. This problem will make impact for process research of their thesis especially for student of final semester. So, it need an evaluation business process for academic service in thesis using FILKOM APPS with quality evaluation framework (QEF) method. The Quality Evaluation Framework (QEF) have some dimension to measure the quality of time service. First step for researcher is modelling the business process base on event log in FILKOM APPS record especially in thesis service with data extraction from Disco tools and the automatically process business modelling with ProM 6.8 tools. Next step with heuristic method, the event log data will modelled automatically. After that we do some mapping for business process modelling from event log and operational standard procedure. After that, researcher do some evaluation with time efficiency matric. The result of this evaluation are the activity of publishing of letter of assignment, verification from academic study program, verification proposal document after P0 and the scheduling of result presentation with this percentage of those activity not reach 100%.

Abstract

LoRa (Long-Range) is a wireless transmission media that was designed to be used on low-powered devices such as sensors and only needs to transmit small data over long distances. The application of LoRa in IoT-based ECG (Electrocardiogram) monitoring will assist patients. However, one of the main challenges in implementing IoT is its data security. Moreover, health data such as ECG data are considered to be sensitive because they are used in medical diagnosis. Therefore, a solution to this vulnerability is implementing a security mechanism between endpoints (end-to-end security). End-to-end security mechanisms can be implemented using cryptography. In this research, an end-to-end security using AES and HMAC algorithm is implemented. AES and HMAC is chosen because the devices that is used are low-powered and only have limited resources. That mechanism is applied to sensor nodes and gateway because they are the endpoints.In this research, an end-to-end security mechanism has been implemented successfully. But, the application of this end-to-end security mechanism has an impact, that is an increase in end-to-end delay that exceeds the tolerated delay limit in ECG data transmission. So, this mechanism isn't recommended to be applied in ECG data transmission.

Abstract

Cement is a material that is used as an adhesive for solid materials namely bricks or concrete blocks into a strong and sturdy unit, usually used for making houses, walls, foundations, roads, or other buildings. In Indonesia, cement production is quite high. In 2017, the total cement production in Indonesia has reached 107.9 million tons. However, high cement production in Indonesia is not matched by the number of requests. As a result, Indonesia experienced an oversupply of cement which caused the price of cement in the market to experience a decline. Therefore, research on predicting cement demand needs to be done as a solution for cement producers in estimating the amount of cement that needs to be produced. In this study, discussing the Fuzzy Time Series method used to predict the amount of demand for cement. The data used is data collected from PT. Semen Indonesia from 2006 to 2018 for each month. From the test results, the smallest MAPE error value was obtained at 10.42% with a parameter value of 80 intervals for 24 test data and 96 training data.

Abstract

Wireless Sensor Networks are a series of nodes. That's nodes will make a network. On this network, there is a Master node that works to collect data from all nodes in the network. If the Master node dies then the distribution process will stop. To overcome this we need an algorithm that can overcome these problems. Bully Leader Election applies an algorithm to select leaders with the highest authority among other nodes. The selection is made by checking the energy capacity of each Slave node and then the Slave node with the largest energy capacity is selected as the Master node. The system is implemented on nodes with the LoRa communication protocol. Each selection process will have the same time slot so sending messages do not clash with each other. The choice of the Master node will be influenced by the energy capacity of each node. The more energy that is owned, the life of a node will be longer. By utilizing the energy capacity in the selection of new masters, it is hoped that the possibility of dead Master nodes will be smaller.
