Abstract

Acute Respiratory Infection (ARI) is a major cause of morbidity (number of diseases) from various infectious diseases in the world. Bacteria, mycoplasma virus, fungi are a small part of various causes of ARI disease. Based on the severity, ARI disease can also be divided into 2, namely mild ARI and severe ARI. The low level of public information about knowledge about diseases, especially ARI, is an important factor why the mortality rate due to ARI is very high. In addition, sufficient numbers of medical personnel are needed to help communities in certain areas of Indonesia to be able to cope with ARI disease and get to know more widely ARI disease. Therefore, expert systems are expected to be a solution or rapid treatment and in helping diagnose ARI. This study also uses the Tsukamoto fuzzy method in the process of calculation and implementation. The application of fuzzy tsukamoto method of diagnosis of ARI disease, applying input from symptoms of ARI that appear as a reference for the diagnosis of disease. In the system, experts provide 5 symptoms and 2 types of ARI disease. Accuracy testing is done by testing the accuracy of 60 training data obtained from experts and there are 53 of the 60 data that match the results released by the system with expert results. The accuracy value obtained is 88.33%.

Abstract

Investors and stock traders need knowledge of forecasting when the price of gold will rise or will decline to minimize the risk in investing. This forecasting requires an appropriate method in order to give good results. FIS Tsukamoto is used to forecast the price of gold based on existing exchange rate data. The parameters used by Tsukamoto FIS are the currency rates of USD / GBP, CHF / USD, JPY / USD, EUR / USD based on the previous three days and the price of gold based on the previous day. To maximize Tsukamoto FIS performance, Tsukamoto FIS membership function will be optimized using Genetic Algorithm. The chromosome representation used is real-coded with a double data type. The reproduction of the crossover method used is one-cut point, while the mutation method used is random mutation. In the selection process, the method used is elitism selection to get the best individuals. Based on parameter testing carried out with 10 experiments each parameter, the best population size is 180, combination of cr = 0.9 and mr = 0.1, and the best number of generations is 325, the best fitness value is 8.6972. The Root-Mean Squared Error (RMSE) value obtained before optimization is 13.3611, while after optimization it is obtained that the smaller RMSE value is 12.5801. These results indicate an increase in the value of accuracy in Tsukamoto FIS after being optimized using Genetic Algorithm.

Abstract

The role of the workforce as Human Resources (HR) that runs operational tasks within the company has an important role in the success of the company. To get a competent workforce it is necessary to conduct an assessment process for the workforce to be appointed as permanent employees in a company. It is also applied by one of the companies in the field of express courier and logistics PT. Tiki Jalur Nugraha Ekakurir or commonly known as JNE. To reduce subjectivity in the assessment process it is necessary to give weighting to each criterion to be used in the assessment process. Analytical Hierarchy Process - Technic for Preference Order by Similarity to Ideal Solution method is one of the combined methods that can help to support decisions in recommending employees. Where AHP is applied to look for priority weights criteria and TOPSIS is applied to rank alternative employees. Accuracy testing is done by using comparison criteria data provided by JNE. The test data used is data from employee recommendations in 2017 as many as 33 employee recommendation data. The results of accuracy testing conducted found that the system's accuracy rate was 69% for permanent employee recommendations, 50% for contract extension, and 80% for contract termination recommendations. In the system acceptance test using the SUS method the value obtained is 80 which in the range of values is the range of "acceptable" values in the SUS scale

Abstract

The more number of chickens can make a very negative impact because of the increasing number of chicken manure in the cage. Chicken manure that is stacked in large quantities in a cage will produce a variety of harmful gases. If harmful gases arising from chicken coops exposed directly to humans will cause directly to the parts of organs in the body and respiratory problems. With the presence of a dangerous gas system in chicken coops, high risk can be prevented and used more easily in anticipating it. To be efficient in running system devices, the device in designing the system will utilize low power work for savings in power consumption. Power efficiency is carried out for battery energy sources used in the device to work in a relatively long period of time. The use of a low power system in Arduino Uno to implement devices on power consumption that is used more efficiently will not run out quickly. Sleep power down mode is used as a feature in this low power so that some sub-systems in the monitoring system of dangerous gas exposure in the chicken coop can be temporarily turned off. The resulting test is in the conclusion that the system can run as desired. Tested with MQ-4 and MQ-135 sensors there is a reading of the detected gas value with the value in the sensor. In testing low power power consumption on a device capable of suppressing currents of 11 to 12 mA from 183.95 mA with normal conditions or wake mode.
