Abstract

Hadoop is a distributed data storage platform that provides a parallel processing framework. HDFS (Hadoop Distributed File System) and Map Reduce are two very important parts of Hadoop, HDFS is a distributed storage system built on java, while Map Reduce is a program for managing large data in parallel and distributed. The research focused on testing the data transfer speed on HDFS, testing using 3 types of data, namely video, ISO Image, and text with a total of 512 MB, 1 GB, and 2 GB of data. Testing will be carried out by entering data into HDFS using the Hadoop command and changing the size of the block size with parameters 128 MB, 256 MB and 384 MB. Hadoop's performance on a large block size of 384 MB has better speed than block sizes of 128 MB and 256 MB because the data will be divided into 384 MB so that data mapping will be less than on block sizes of 128 MB and 256 MB.

Abstract

Single Tuition Fee or UKT is a tuition fee borne by students every semester. Payment is made every time students enter a new semester while studying at tertiary institutions. One of the state universities in Indonesia that has implemented the UKT payment system is Politeknik Negeri Ujung Pandang. Based on observations, the purchase of UKT is still done manually, so it has the potential to produce decisions that are not on target. This study was classified based on the amount of single student tuition fees using the smote method and without smote. The algorithm used in classifying is SVM, Decision Tree, Random Forest. The data used is 985 UKT data in 2021. Based on experiments that have been carried out with the Random Forest algorithm, it has the best performance compared to the SVM and Decision Tree algorithms. The proportion of results obtained before being hit is accuracy of 84.75%, precision of 79.22%, recall of 81.15% and F1 score of 80.17%. Whereas after applying smote it increased with an accuracy proportion of 98.9%. So it can be interpreted that the best algorithm used in classification is the Random Forest algorithm by applying smote.

Abstract

In agriculture, the drip irrigation system is still using a manual system, so it is necessary to develop an automatic irrigation system that can make it easier for farmers to control water supply. network The use of wireless sensors in agriculture is a field that is experiencing an increase. Using a wireless network helps farmers when they have to carry out cable maintenance and repairs in areas that are difficult to reach. This study aims to implement a wireless sensor network based on ESP8266 for drip irrigation system automation that monitors changes in soil moisture and plant temperature, as well as automatic drip irrigation control. The method used in this study is the Waterfall Method, this model develops systematically from one stage to the next. The maximum range distance that can be achieved by the router node to send data to the sink node is 140 meters at the Line Of Sight (LOS) position. At the same time, the router node also controls drip irrigation automatically by sending commands to the actuator node (drip controller) to open or close the solenoid valve connected to the water reservoir which will circulate air by gravity. To implement it, you need ESP8266, YL-

Abstract

RSUD Labuang Baji has a lot of medical record data, but this medical record data has not been used optimally and has not been processed to produce useful information for Laburan Baji Hospital. In this study the data used were outpatient medical record data in 2019, by analyzing three attributes, namely disease diagnosis (ICD), gender, and age group. The method for conducting data analysis is the association rule method using the Apriori algorithm and Tools R. The results of this study are disease patterns using a minimum support value of 0.01 and a minimum confidence value of 0.6, and the disease pattern formed is an associative rule with a combination of 2k-itemset and 3k item set of 25 associative rules where the rules for this disease pattern have a lift ratio value of > 1, so this disease pattern can be used as a recommendation to improve hospital services.
