Abstract

Agriculture has now been transformed using a variety of technologies to increase production. Traditional agriculture has shifted to smart farming that utilizes the Internet of things using Wireless Sensor Network (WSN) as an information gathering and monitoring control application. The 802.15.4 protocol based agricultural land monitoring system has reliability in monitoring and sending data, this system runs for a long time, so an effort is needed to save energy in the system using the Low Power method so that the use of resources is reduced. In applying the Low Power method use the sleep mode powerdown feature which will forcibly turn off some work functions from ATmega328P. In the implementation of this system 3 Nodes are used, among others: 2 End Devices that perform data retrieval and delivery, and 1 PAN Coordinator as a server or data receiver. The test results using the Low Power method get savings of an average of 6 mA or 12.7%, namely the average value of the current when the system wake is 47.7 mA and when sleep is 42.3 mA. In addition, based on packet loss testing, data transmission is obtained at the optimal distance of 25 meters between End Device and PAN Coordinator.

Abstract

OWASP Mobile Security Testing Guide (MSTG) is a method that can be used for security testing on mobile device applications both based on iOS and Android operating systems. Security testing is needed to minimize vulnerabilities in an application. However, there is currently no security testing application that applies OWASP MSTG, so this research will create a security testing system that applies OWASP MSTG. In the requirement analysis process there are 11 functional requirements while the design phase will make the system design, interface design, and algorithm design. This system is implemented on a web-based using CodeIgniter framework. On system testing, the system is tested by functional testing and validation testing by comparing the results of the system that has been made with existing security testing applications. Based on the system testing, the security testing system OWASP MSTG has been running and accordance with the system design stage.

Abstract

Routing is the process of selecting the best route or route that must be passed so that packets get to the destination quickly. Most of the application of RIP and OSPF protocols on real networks and previous studies still use a lot of IPv4 networks, which we know is that the number of IPv4 address allocations in the world has decreased over the years. This study tries to use IPv6 addresses implemented in the RIP and OSPF routing protocols in the form of simulations in the Riverbed Modeler software to determine the performance of the two routing protocols by adding disconnections and recovery paths for sending data packets or failure recovery. The purpose of this study is to determine the best routing protocol in overcoming failure recovery from two IPv6-based RIP and OSPF routing protocols by comparing the performance of three parameters namely metric cost, convergence actvity, and routing traffic. The test results obtained from this study that the OSPFv3 routing protocol has a performance superior to RIPng in convergence activity and routing traffic. Difference in convergence activity speed of 8,59 seconds in scenario one and 3,39 seconds in scenario two. Difference in the average amount of traffic 153163,33 bps in scenario one and 109214,08 bps in scenario two. The conclusion from this study, that the best routing protocol in overcoming failure recovery is the OSPFv3 routing protocol. The metric cost parameter does not participate in determining the best routing protocol in overcoming failure recovery, because each routing protocol has its own algorithm in the routing process or has its own metric value in determining the best path that distinguishes between routing protocols.

Abstract

Blind people have a condition that their sense of sight is not functioning properly. The condition causes the blind have difficulties in mobility. Solution for these conditions is use a stick. Mobile devices can be a new solution for this problem because mobile devices are capable of many processes. This system was built using a camera from a mobile device as a substitute for the sense of sight. The results of the camera are then extracted features using the GLCM (Gray Level Co-Occurence Matrix). Once the feature is obtained, the classification is done by algorithms KNN (K-Nearest Neighbor). The classification used to determine these features is the floor or obstruction. If the result of the classification is an obstacle, the next process is to turn on the buzzer as a sign to the user that a obstacle has been detected. . This system has good detection accuracy when using a small ROI (120x213 pixels) of 90% compared to ROI (360x640 pixels) of 60%. In real time the system has a 100% accuracy in obstacle detection for white floor objects, 82% for obstacles with wooden door objects, 93% for white obstacles and 93% if detection is done on 2 different objects in 1 video. Integration of hardware and software on this system has an accuracy value of 88.8%. For computing time this system has an average value of 248.8 ms, a minimum value of 183 ms and a maximum value of 582 ms.

Abstract

Indonesia has numerous disaster-prone area, therefore, it is known as a 1001 disaster country. Natural disasters are inevitable, nevertheless, the impact can be minimized with proper anticipation. One of the disasters that often occur in Indonesia is volcanic eruption. Indonesia has 127 active volcanoes that are ready to erupt anytime. Indonesia is also known to contribute to around 30% of the world's volcanoes, and they are located near the residential areas. Casualties are often found in every volcanic eruption due to lack of anticipation from residents who live nearby the volcano. To minimize life and material loss, early warning is needed to provide quick and accurate notification of the volcano. This research used the Modified K-Nearest Neighbor method to classify volcano status. The data used are 110 data obtained from the official government agency that authorized to issue volcanic status, known as Pusat Vulkanologi dan Mitigasi Bencana Geologi (PVMBG). The test was carried out using various k values, namely 3,5,6,7, and 9. The highest accuracy obtained in this research was 86.87%, and the average accuracy was 82.87%.

Abstract

The freshness of milkfish is influenced by several factors, one of which is the time of storage of fish. In the process of storage and processing at traders and households, it is still done manually and causes errors in determining the freshness of milkfish. To overcome these problems, a tool that can determine the freshness of milk fish will be designed quickly and automatically. In making this tool an arduino microcontroller and MQ135 gas sensor will be used to detect ammonia, and TCS3200 sensor to detect the RGB color of milkfish. The results of the two sensors in the form of 4 parameters or features will be used to determine the freshness of milkfish with the Naive Bayes method ... The Naive Bayes method was chosen because this method is very flexible if there are changes to the training data, and requires little training data to can do Naive Bayes calculations, and finally the results of the classification method are also quite accurate. From the testing carried out starting from the sensor testing method and computational time the result is the TCS3200 error percentage when detecting RGB meat is 2.2%. In testing the sensor MQ135 sensor correlation value obtained with an output voltage of 99.22%. For testing methods using 100 training data and 18 test data, classification using Naive Bayes obtained an accuracy of 94.4% with an average computing time of 2.7 seconds.

Abstract

Fingerprint scanner's presence infrastructure is a system that is widely applied as a presence today such as the Faculty of Computer Science (FILKOM). The presence system using a fingerprint scanner can help staff for recording attendance data, as well as calculating the performance of the employee. However, there are problems that arise from using the fingerprint scanners as a presence system, including the presence of attendance recapitulation which is still manualy calculate, asynchronous employee attendance with attendees result, transparency of the attendance data is unknown by the employee. The solution to this problem is to make each civitas have a tool that is used to make a presence, so that the presence can be done by the civitas themselves and attendance data can be directly obtained by staffing staff. From this solution a system was developed to use a smartphone as a media presence because this device is owned by each civitas, sensors owned by smartphone devices are also complete such as WIFI sensors, fingerprints and cameras. The author develops an Android mobile-based system as a presence by utilizing fingerprint sensor, camera and WIFI. WIFI is used as a virtual fence so that the community who wants to attend must be present in the FILKOM environment, the development of this system carries the REST API technology that is useful as a bridge between mobile presence data and computer staffing staff used as a recapitulation tool for community attendance. This presence system was developed with the software development life cycle, which is the waterfall method where needs have been defined at the beginning and there is no change until the design, implementation, and testing process of the system has been developed. Tests carried out include: unit testing on four methods with valid results, validation testing on 38 functional requirements with all valid results, integration testing by checking the interaction of two methods with valid results, and compatibility testing using three devices with valid results. From the test results obtained by the system developed has met the requirements that have been determined, for the appropriate system, valid results and running on Android devices version of Lollipop to Pie

Abstract

The importance of non-medical services in the fulfillment of facility services at hospitals in addition to health services. Seeing the amount of linen needed in each hospital room by handling it properly. Linen services are carried out to meet the interests of patients in conducting care, so that linen cleanliness needs to be considered with linen laundry. In its application, problems arose including manual recording, incomplete information in the linen laundry service process, and records made again by the head of the household unit for recapitulation. This reduces the sense of satisfaction for the laundry service process and related to the efficiency of time and cost of using books as well as the possibility of major problems that occur because the fulfillment of laundry linen is done every day by officers. Based on the problems that occur the construction of a web-based linen laundry service information system is carried out by applying the waterfall method in system development. Testing is done in four ways, namely unit testing of five samples that were tested using white box testing techniques obtained results of 100% valid status. Validation testing of 42 test cases obtained 100% valid status results. Compatibility testing with system results can run on 11 browsers. Usability testing using the System Usability Scale (SUS) method of 87.5 with excellent and grade scale B categories, which means that the system usability can be accepted.
