Abstract

Wireless technology has begun to develop and connect with each other, so this is what makes a basis for the development of the Internet of Thing technology or abbreviated as IoT. There are several elements in helping the performance of IoT technology, one of which is in terms of communication. LoRa is a wireless transmission communication technology using Chirp Spread Spectrum (CSS) as a modulation technique of its delivery. LoRa uses Pure ALOHA as an access method for sending data where two or more nodes send data at the gateway without coordinating with each other, causing the risk of data collisions. In this study using the master-slave method to send data to avoid data collisions. Gateway node acts as a master whose job is to send data request messages to the sensor node. The sensor node acts as a slave whose duty is to send sensor data to the gateway node that acts as the master only if the master requests the sensor node specifically based on the slave ID that the sensor node has. Functionality and non-functional tests are carried out to test whether the system is operating properly. The smallest percentage of packet loss is experienced under test conditions at a distance of 50 meters where packet loss only occurs in the process of sending from sensor node 1 to the gateway, while the largest percentage of packet loss is experienced under test conditions at a distance of 200 meters on a 30 minute test duration of 8.99% . The smallest average delay test results are experienced in testing conditions at a distance of 200 meters with an average delay of up to 160.64 milliseconds, while the largest is experienced at a distance of 100 meters with an average delay of up to 405.67 milliseconds.

Abstract

There are many routing protocols used in the current network topology. EIGRP, IS-IS and OSPF are examples of routing protocols in a network topology. each of these routing protocols has different algorithm to communicate and also has different ways of working algorithms. Therefore, additional methods such as route redistribute are given so that different protocols can communicate in a topology. In this research, an analysis related to the route redistribute method to find which routing protocol has the best performance in the same network topology. This study uses the Graphical Network Simulator 3 or (GNS3) and uses a hierarchical topology. The scenario is to send an ICMP PING packet from source to destination to observe the round-trip time and convergence time. The results showed that each routing protocol can be run by the route redistribute method. The IS-IS protocol has a round-trip time of 531.4 milliseconds and a convergence time of 158.2 seconds that makes time is the lowest time compared to other protocols and proves that the ISIS protocol is able to work well on the route redistribute method.

Abstract

Water is the essential compound for all living things on this earth. Human needs fresh water for their daily activities. Because of the importance of water use, the quality of water must be maintained. Make a water monitoring system can be one of the ways to maintain water quality. The monitoring system can be done by using the Internet of Things (IoT) technology. In the application, it will be constructed by three main component systems such as Producer, Broker, and Consumer. In building the IoT network architecture communication protocols are needed between the nodes to exchange data. The protocol that is used in this research is the Advanced Message Queueing Protocol (AMQP) and WebSocket. The AMQP was chosen because the network used in this research was considered capable of suiting the needs of the AMQP protocol. WebSocket protocol used for means of data communication so the results of monitoring can be shown on a web page in real-time. According to the result of tests conducted indicate that the system is capable of real-time monitoring, it's based on delay value in data transfer obtained. By using this water quality monitoring system, it is hoped that later it will be able to monitor the quality of water in real-time via the web.

Abstract

Agricultural development can be done by forming an institution that functions as a forum for information and learning about agriculture to farmers, one of which is by forming farmer groups. But there are some farmer groups that are often abused. This condition has an impact on the development of farmer groups that tend to decline from year to year. Efforts to foster and empower these farmer groups must also be adjusted to technological progress and demands on the application of agricultural development programs. Therefore in this study the method used is the Implementation of the Fuzzy AHP (Analitycal Hierarchy Process) - COPRAS (Complex Proportional Assessment) Method. The Fuzzy AHP method is considered more accurate in weighting criteria than the AHP method. And the COPRAS method is more accurate in calculating alternative ranking because the evaluation of maximum and minimum criteria is done separately. Based on the results of the implementation of the AHP (Analitycal Hierarchy Process) - Copras (Complex Proportional Assessment) method for the recommendation to determine the best farmer group, it has an accuracy rate of 68% (using 25 data) and 48% (using 50 data). And having the same interpretation coefficient of correlation has a close to perfect relationship (ρ> 0.9). This shows that this method is able to help and make decisions.

Abstract

Gapura UB is an academic portal mobile application to access academic information and services in the Brawijaya University campus environment. Based on the results of interviews with the developers, stated that the application has never been evaluated usability by testing usability to its users or conducted an inspection by an expert. Even though usability evaluation is an important element that makes it possible to add insight into usability problems in the application. This study aims to identify the usability problem of the application and compare the effectiveness of four evaluation methods used in this study: usability testing, interviews, surveys, and heuristic evaluation. Data is collected from users in the student category and expert evaluator. Details of the number of respondents used are usability testing (N = 10), interviews (N = 10), surveys (N = 110), and heuristic evaluation (N = 3). The four methods together identified a total of 44 usability problems: 45% through heuristic evaluation, 24% through surveys, 17% through interviews and 14% from usability testing, with a few similar findings. These problems are then categorized using Usability Taxonomy Problem (UPT) which divides the problem into 5 categories with details of 17 categories of visualness, 6 categories of language, 3 categories of manipulation, 11 categories of task-mapping and 7 others including the category of task-facilitation. The results of this study prove that the four methods are complementary, each method provides a unique insight to improve the usability of the application user interface. The researcher recommends using a multi-method approach when evaluating application usability because it can provide a more comprehensive representation of usability issues.
