Abstract

To test the performance of the MQTT broker using containerization technology on Raspberry Pi devices with two different image bases, we use several experimental parameters. The experimental parameters are resource usage (CPU and memory), latency, and packet loss. To test the resource usage, we created a Python script. Meanwhile, to test latency and packet loss, we used the MQTT broker measure latency measure. The base images used as the installation media for the MQTT broker (Mosquitto) are belenalib/raspberry-pi2 and belenalib/raspberry-pi2-alpine. We created the Docker images using Dockerfiles. The image is built and run with the commands provided by the Docker program. Regarding resource usage (CPU), the MQTT broker running on docker based on the belenalib/raspberry-pi2 image performs better than native with 0.53% to 10.38% lower CPU usage. However, the resource usage (memory) of both MQTT brokers running on docker is still higher than MQTT brokers running natively, which has a difference about more than 50%. Likewise with the latency test, the two MQTT brokers running on docker are still higher than the MQTT brokers running natively, which has a difference of more than 50%. While in the packet loss test, the MQTT broker with the belenalib/raspberry-pi2 image base can provide better performance where only 28.60% experienced packet loss on 1000 MQTT clients and 0 QoS.

Abstract

Speech recognition research with end-to-end model-based bidirectional RNN approach still has the constraint on high latency. speech recognition model which was built using end-to-end models still have some problems at error spelling. Also, speech recognition model is very sensitive to dialecta and types of equipment recorder speakers. This work will examine the behavior of the network in studying the acoustic features based on gradient and loss with the use of unidirectional base GRU CTC which has lower cost of computation compared to the base bidirectional RNN CTC. This study did not use the language model in helping to model the acoustics in the mapping of the acoustic signal. Using the data in the audio translation of the Quran in the dialect and Bahasa Indonesia, the data extracted using the MFCC to obtain acoustic features. Batch Normalization is also used on the GRU network to avoid covariate-shift between the layers of the network. The network consists of three-layers network MLP with activation function ReLU and forwarded with a layer of unidirectional GRU. After passing through the GRU, the data will be processed on the SLP with the function of the activation of softmax where the results will be input on the CTC. The network is optimized using Adam optimizer and generate 90.611 % WER of the best model tested. The network has a vanishing gradient and results in the slow process of learning the network in recognizing the acoustic signal. The use of unidirectional GRU base also has no big significance in the delay layer to expose the temporal information.

Abstract

Pagerngumbuk is a village located in Wonoayu, Sidoarjo. The total population is approximately 3118 people consisting of 1,434 men, 1,684 women, and 920 families spread over 3 hamlets. In Pagerngumbuk Village, there are letter processing services, aspiration complaints services, and village's informations. Problems arise if the Headmen is not at the office because he is on duty outside the city for a long time. Another problem that arises is that there are residents who cannot process documents due to work constraints or living outside the city. Based on the existing problems, a web-based system has developed that can accommodate the residents in conveying aspirations/complaints, managing letters, and delivering village's information in an integrated manner. The system is built using the Waterfall model which then produces 5 types of actors, 69 functional requirements, and 1 non-functional requirement. Whitebox testing uses unit testing of 3 functionals resulting in each path that has been defined can be passed. Blackbox testing uses validation and user acceptance testing, each test produces a 100% valid value. Then compatibility testing on non-functional requirements found several major and minor issues when the system was accessed with an old version browser, but it did not affect on functionality.

Abstract

Sidoarjo Regency is an area that has very good and strategic investment land in the East Java region. This can be proven by the amount of investment that comes in from 2014-2018 has always increased. This amount of investment is not matched by the amount of land available for new investors, especially in the city center of Sidoarjo Regency. Sidoarjo Regency Government seeks to develop urban areas throughout the districts of Sidoarjo Regency. The existence of this urban area is needed to meet the availability of land for new investors who want to invest in the city center of Sidoarjo Regency. This research developed a geographic information system to determine the suitability of land in an urban area in Sidoarjo Regency using Multi-Criteria Evaluation and AHP methods. Criteria such as urban settlements, social services, and economic activity are used in this research based on the regulation of the Minister of Home Affairs of the Republic of Indonesia number 57 of 2010 on Guidelines and Standards for Urban Services. The result of this research indicates that the land area of 385,831 km2 (54.21%) is very suitable to use an urban area of Sidoarjo Regency. Only 2.08% of land in Sidoarjo Regency stated not suitable. The result of accuracy testing using receiver operator characteristic method to analyze result model stated pretty well.
