Abstract

Stream processing is becoming essential of IoT stack to increase the values and benefits for the organization. Along with the growth in streaming data, centralized architecture will cause large delays for providing service. To solve this problem, additional resources or machines in the cluster are needed to maintain processing performance. This research proposes to develop a distributed IoT data stream processing platform using Spark Streaming. Throughput and latency show high results, 321.4 records/s and 13.3 seconds, if the amount of data processed is less than the available resources.While the system capability scenario of up to 12 seconds of batch interval shows the highest throughput and latency, 2112.4 records/s and 5.93 seconds. Furthermore, the fault tolerance scenario shows that 6 nodes can process faster with 60 seconds. Spark Streaming also shows the ability to use distributed resources efficiently by showing CPU and memory usage across all nodes having no significant differences. The average difference in memory and CPU usage at each node is 3.6% and 2.04%.

Abstract

Coffee cultivation in Indonesia is still done by very traditional methods, like wise in determination of its quality level by sorting it out still done by human operators by considering its size and density, which means determination of coffee bean's quality level is very depended on the operator's ability, so that is susceptible to mistakes and non-technical factors that accompany it. The quality level of coffee bean itself is divided to 6 grades that is grade 1 to grade 6 for each variant. One of the methods that can be done to ease determination of the quality of coffee beans is by processing its image by extracting texture feature by using Local Ternary Patterns(LTP) method, color feature with HSV and RGB Color Moment, and utilizing classification algorithm Learning Vector Quantization (LVQ). This method is considered as a breakthrough in coffee bean's grade determination because the cost is cheaper but still gives decent results considered in a relatively short time. In this study, the image data used is as many as 150 data with 30 data on grade 1 through 5 because the data availability was not up to grade 6. This study results a system that was able to classify the quality of coffee beans with an accuracy rate of 84,4%. Two of the entered quality cases were successfully predicted with 100% correctness, namely grade 1 and 5.

Abstract

Currently the face-to-face learning process can no longer be carried out due to the 2019 coronavirus disease (covid-19) pandemic which has spread in Indonesia. The spread of Covid-19 has a major impact, especially on the education sector. The temporary closure of educational institutions is an effort to contain the spread of the Covid-19 pandemic. Teachers at SMP Negeri 1 Merek also experienced the same thing, most of whom were unfamiliar with the use of technology. Habits in the face-to-face learning process make teachers experience many obstacles in teaching online. Some teachers when they try to use technology for the first time are successful, but they forget to repeat the same thing on a different day. This descriptive study is expected to produce an explanation of the results of the analysis based on the exploration carried out. Exploration is carried out by means of interviews to explore teacher experiences during the online distance learning process. The results of the interviews with seven resource persons were then made transcripts and analyzed by thematic coding, in order to obtain the appropriate theme / categorization. It is hoped that this research will produce documentation that can be used to find out what was experienced by the teachers and what technology was used during the online distance learning process. Based on the research that has been done, teachers at SMP Negeri 1 Merek use whatsapp and classroom applications.

Abstract

The use of applications installed on smartphones, especially Android, is currently very much used by a Muslim or Muslimah to support prayer activities. One of them is a reminder application for prayer. However, most application reminders are intended only for prayer that is compulsory while the sunnah prayer activities are still relatively small. Another disadvantage is that the application is not able to automatically provide reminders to users that are adjusted to the location, time and activity of the user whether they have performed the prayer or not. For that we need a context-aware concept that is expected to be able to optimize the reminder function so that the application can provide reminders according to user activities. By utilizing context information in the form of location, time, identity and activity of the user through the sensors that are on the smartphone, the application can find out whether the user has carried out prayer or not. Sensors that can be utilized include GPS sensors, proximity sensors, light sensors and accelerometer sensors. The level of efficiency of the use of the application was tested using usability testing and it was found that SUS score of 74 included in good qualifications and success, then in compatibility testing the Sunnah prayer reminders application can run smoothly and there was no error in the Android operating system Lollipop, Marshmallow, Nougat, and Oreo.
