Abstract

The main network infrastructure that is almost entirely managed by vendor leads to the increasing complexity of network built, so it is needed an approach to manage and implement the network to support the diverse needs, that is the needs of using Software defined network (SDN). Software defined network (SDN) has a basic concept of separating the control plane and data plane, so the network can be programmed individually from the data center. Some of the existing controllers are Maestro, Floodlight, RYU, POX and ONOS. To know which controller has the best performance, then doing a performance comparison analysis among the controllers. Tests conducted in this research is using mininet as an emulator to design test topology and Cbench to evaluate parameters of throughput and latency. Based on the test, we found that Maestro controller has better capability to handle data flow with larger amount of data compared to Floodlight controller, RYU controller, POX controller, or ONOS controller. Thus, the Maestro controller has a better chance to guarantee the processing of large amounts of data. With the difference of throughtput value in the range of 500 to 4000 flow/s. With Maestro controller, we also got better and superior latency values with the difference range of around 1000 ms up to 5000 ms.

Abstract

ABSTRACT Nowadays. the topic about energy scarcity issue becomes quite often discussed in the development of modern technologies such as wireless sensor network (WSN). From many of its implementations. WSN's main problem is about energy consumption. This is happened because the power supply of the node only supplied by a battery for its operation, so it has limited energy reserves. If one node dies, it will change the network performance in terms of routing and topology. In this study, a battery capacity measurement module is implemented on an embedded device. If the battery capacity information of the battery is known, then the approximate time of how long the embedded device can continue running will also be know, and so it can support the further development of energy savings on embedded devices. In its implementation. the module uses a resistor shuntto obtain a the value of drop voltage which is then can be used to measure the current flowing on an embedded device using Ohm's Law. When the current is known. the battery capacity can be calculated. Value processing is done by using arduino nano microcontroller. The module then provides battery capacity information in the form of percent value and the current flow value on the embedded device via LCD. It is concluded that the module can measure the current flow of the embedded device and the module can also calculates the battery capacity that used by the embedded device. The module works with a 94,56% accuracy level in measuring battery capacity.

There is a proof that own good cardiorespiratory fitness can reduce cardiovascular disease like heart attack and stroke. Therefore it's important to have good cardiorespiratory fitness. Cardiorespiratory fitness can be measured by level maximum oxygen body can take (VO2max). There is a method for prediction of VO2max without doing physical activity using heart rate rest, body weight and age (non-excercise prediction method). Measuring Heart rate and body weight for calculation VO2max with non-excercise prediction method use 2 sensors, pulse sensor and load sensor. In order to facilitate VO2max calculation and displaying attractive result, then used android OS-based devices as an intermediary by utilizing the HC-05 Bluetooth module as a medium of data exchange. Applications built on android OS based devices are also equipped with suggestions for improving good VO2max so that it can be a guide for users. Tests on sensors in VO2max measurements resulted in an error of 8.12% for pulse sensors and 0.92% error results for load sensor. The maximum effective range that can be done by the Bluetooth module HC-05 is 10 meters. The method performed can easily measure VO2max without having to do physical activity so as to facilitate in the supervision of cardiorespiratory fitness of the body.

Abstract

Progressive Web Apps (PWA) is a Mobile Web that uses the latest technologies to create a Mobile Web with better user experiences than traditional Mobile Web. Creating a web application with such experiences, one thing that can not be forgotten is performances and the technologies behind it. Speaking of performance, many aspects could be considered, such as responses time, memory usages and storage usages. Thus, this study will discuss about comparisons between PWA and Mobile Web related to those aspects in order to provide some insights and references of this newly introduced technology. From this study, there are some things that can concluded. Response time performance depends on page resources size, caches size and the access frequencies. On a small sized page and small sized cache files, Mobile Web still faster than Progressive Web App, while on large sized page and cache files Progressive Web App is the winner. In memory usages performance, Mobile web uses memory fewer than PWA due to an additional process that PWA has (Service Worker). In storage usages performance, Mobile web is not using any of storage spaces, while the storage usages of PWA depends on the size of the caches stored in the browser.

Abstract

Fish feeding is generally still very dependent on human resources that are still manual. Also knowing the temperature in the aquarium water is also necessary for the maintenance of fish. However, there is still much indifference to the temperature and feeding of irregular fish. So we need a system of fish feeding automation and monitoring of temperature conditions in the water. In this system using DS18B20 temperature sensor to know the temperature in the aquarium and loadcell sensor is used to determine the availability of fish feed on the container. The loadcell sensor is used to determine the change of the weight of the container that holds the fish feed, so that information is forwarded to the application. Information obtained by hardware is sent to the application using MQTT protocol communication where data is sensed. The hardware acting as a publisher will send the data to the broker. Applications android acting subscriber will display data in the form of water temperature information, the availability of feed and fish feed scheduling based on information obtained from the hardware. Based on the results of the tests performed is the average percentage error error of 21.87%. Then for the average weight value of feed out for 5 seconds of 28.29 gr. Scheduling for open feed cover is done every 1 minute.

Abstract

Fire phenomenon is a familiar phenomenon in Indonesia. The high number of fire incidents in Indonesia requires special attention from the government, so that any natural disasters such as forest fires can be overcomed. Satellite monitoring results are recorded on a data file of fire points with a large enough data numbers so that the data is difficult to be processed to become information that is easily received by the user. Based on data obtained from the EOSDIS site recorded as many as 289,256 fire spots occurrence in the region of Sumatra in the timeframe between 2001 to 2014. It takes an algorithm to segment the data or cluster the data, so that large data can be processed into a good information for the user. In this study a comparative study of clustering algorithms between K-Means and Isodata was conducted. Both algorithms used in this study were assessed based on the quality of the clusters produced. The algorithm used in measuring the quality of cluster in this research is Silhouette Coefficient (SC). The final result value of Shilhouette Coefficient K-Means method is 0.999997187 and Isodata method is 0.999957161, so in this case, K-Means algorithm has a higher SC value compared to the Isodata algorithm in clustering the data of fire spots with a small SC value difference.
