Abstract

This study applies data mining in determining recommendations for mustahik. The application is carried out using a classification method with an artificial neural network algorithm where the attributes used are age and type of work of the head of the family, the condition and ownership of the residence, the place of sewage, family monthly income, number of dependents, and diet. Tests are carried out using a combination of values ​​between learning rate, epoch, k-fold, and hidden layer neurons. Based on the test results from the classification process, it is found that the artificial neural network algorithm has the highest accuracy when the number of hidden layer neurons is six, the learning rate is one, the fold is seven, and the number of epochs is 200, which is 92.09%. The test results are then displayed on the Mustahik information system page.

Abstract

The conventional question and answer method has limited time, space and level of understanding from each student so that it becomes an obstacle to the ineffective teaching and learning process. Global pandemic events that have a negative impact on the education sector. So that the teaching and learning process is temporarily stopped at school and diverted online. This study aims to produce a chatbot application as a media for distance learning that helps the teaching and learning process of teachers and students . In practice, This research uses telegram as a chatbot media. The method used for data collection is by interview, literature study, and observation. Testing will be carried out with a black box, calculation of accuracy, and a user acceptance test in the form of distributing questionnaires. The results of this study produce a Chatbot Application as an E-Learning Media for Students that can help teachers in providing distance learning to students efficiently and easily.

Abstract

Penelitian ini dilakukan untuk mengukur kinerja dari protokol HTTP/2 dan cara untuk mengaktifkan protokol ini, sehingga protokol ini dapat diimplementasi dan mempercepat kinerja dari berbagai web server. Berdasarkan hasil penelitian ini, ditunjukkan bahwa pengimplementasian protokol ini dapat berjalan pada web server apache versi 2.4.17. Pada pengukuran kinerja yang dilakukan bahwa kecepatan response time yang dihasilkan HTTP/2 dalam mentransfer data lebih kecil dari pada HTTP/1 dapat dilihat dari hasil response time HTTP/1 web server apache sebesar 128,6 ms sedangkan pada HTTP/2 86,3 ms, dan pada web server nginx juga menunjukkan response time HTTP/2 lebih kecil dari pada HTTP/1 yang sebesar 184,3 ms dan 141,6 pada HTTP/2. Dari hasil pengujian response time HTTP/2 menunjukkan performa kecepatan yang lebih cepat jika diterapkan dalam web server apache dari pada menggunakan web server nginx. Apache Web Server Performance Evaluation using the HTTP2 Protocol Abstract: This research was conducted to measure the performance of the HTTP/2 protocol and ways to activate this protocol, so that this protocol can be implemented and accelerate the performance of various web servers. Based on the results of this study, it was shown that implementing this protocol could run on the Apache web server version 2.4.17. In the performance measurement carried out that the speed of response time generated by HTTP/2 in transferring data is smaller than HTTP/1 can be seen from the results of the HTTP/1 web server response time of 128.6 ms while on HTTP/2 86.3 ms, and on the nginx web server also shows HTTP/2 response time is smaller than HTTP/1 which is 184.3 ms and 141.6 on HTTP/2. From the results of HTTP/2 response time testing shows the performance speed is faster if implemented in the Apache web server than using the Nginx web server. Keywords: Apache, HTTP/1, HTTP/2, Nginx, Response-Time.

Abstract

This study aims to destroy an automatic egg incubator, where the performance parameters to be monitored are the temperature and humidity of the incubator. The monitoring system uses the Internet of Things (IoT) application. The egg incubator utilizes the lamp's heat to maintain the room temperature's stability. Utilizing the DHT11 sensor, the temperature data will be processed on the Wemos d1 microcontroller, which is then sent to the internet wirelessly. The temperature and humidity data results will be read in real-time using IoT with the Blynk platform, which can also be accessed using a smartphone. The results of this study apply IoT technology to the monitoring system for measuring conditions of the incubator temperature and humidity parameter values. All device modules will be packaged into embedded systems integrated with environmentally friendly IoT innovation rules and support the technological era of the industrial revolution 4.0. The results of measurements at the incubator's location and the monitoring using the Blynk application are relatively the same, and the success rate of hatching eggs reaches 74% of the total eggs put into the incubator

Abstract

The Minasa Upa Village Office is a community service facility fulfilling population administration and licensing. Currently, the service applied is still carried out in a conventional way, which requires residents to come and queue at the village office to receive services. It is necessary to come to the village office to obtain information on the requirements for making a letter, to find out whether the submitted letter has been completed. Based on these problems, a system is needed to help services at the Minasa Upa Village Office be more practical and efficient. This study implemented an E-Government system that utilizes information technology in service. The e-Government implemented is in the form of an Android-based application designed using the Java programming language and firebase as a database service. The application design method used is the System Development Life Cycle (SDLC) with a waterfall approach. The system testing technique used is black box testing which consists of two stages, namely alpha and beta testing. The results indicate that the application is built according to the expected needs. This is proven through the tests that have been carried out. In addition, based on the questionnaire results, users stated that the interface of the application was easy to understand, with an average score of 86%.

Abstract

Makassar City is the fourth-largest city in Indonesia and the largest in Eastern Indonesia with an area of 175.77 square km and a population of ±1.5 people in 2019, divided into 15 districts and 143 sub-districts. Uneven population density in each sub-district has an impact on the emergence of social problems in society such as: unhealthy environment, chaotic building management, population registration information that is not updated. To overcome this problem, it is necessary to have population info graphics that show the population, age of the population, education, etc. With info graphic data on the population of Makassar city that can be accessed online, people looking for data can use it as a reference. To achieve the objectives of this research, the K-means algorithm method is used to divide observations into K clusters where each observation is a member of the cluster with the closest average value, through an iterative process until the grouping converges. The K-means algorithm can be used on population data. For example, the grouping of population data is divided into three clusters, namely (cluster 1) dense, (cluster 2) medium and (cluster 3) not dense. The results obtained show that five districts: Mariso, Mamajang, Makassar, Bontoala and Tallo are the districts with the densest populations.
