Abstract

Augmented Reality (AR) refers to a direct perception of the surrounding environment that has been added to the virtual component of the computer. There is generally no default mechanism for storing sequences in the AR framework, which in this context is Vuforia SDK. Linked List is one of the methods in Algorithm and Data Structure used to organize data structures in a system. The operand and operator sequences are highly considered in arithmetic operations in order to perform arithmetic calculations correctly, especially for non-commutative or non-associative operations. This research was conducted to apply the use of Linked List into AR as a method to store the temporary sequence of marker that successfully read by the device then processed again in sequence as simple arithmetic operation using Unity 3D engine aid. From this research also conducted whitebox testing with value of result of cyclomatic complexity is 9, which states the system meets the needs according to the design with low complexity, and usability testing with average SUS yield value is 55 which means the system is not yet feasible for use on the novice user.

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

Motorbikes are transportation that are generally in great demand by citizens of developed countries, especially Indonesia. With the increasing population and enthusiasts of motorbikes, the number of accidents in traffic will increase every year. The lack of handling of motorcycle accident sufferers at the time of the incident resulted in a high mortality rate. By knowing the slope of the motorcycle can be stated as an accident. Namely the slope of 10 ° - 50 ° for the left and the slope of 130 ° - 170 ° for the right. Therefore an accident detection system was built on a motorcycle based on the slope using a sensor gyroscope which was used to read the slope of the motorcycle, then sent a notification in the form of an SMS to the victim's family's cellphone via the GSM SIM900A Module. The MPU6050 sensor which is the reader of the slope value on the system installed on the motorbike will be processed on the Arduino Uno microcontroller. If the slope reading is stated as an accident, the GSM SIM900A Module will send a notification in the form of a help message to the relatives or families of the victims with the number that already exists on the GSM SIM900A module. By doing the slope alternately between left and right is selected with the roll value in the MPU6050 Sensor ranging ± -80.00- ± 50.00 expressed with an angle of 10 ° -50 ° and the slope value ± -20.00- ± 74.00 then expressed at an angle of 130 ° ¬ -170 ° the angles are expressed as the angle of the accident on the system and the boundary conditions are 60 ° -120 ° where the roll value is ± -21.00 - ± 1.00 which is declared as a normal system or does not send messages. The system will read the slope if it does not meet the boundary conditions of the roll angle, the system will immediately send a notification in the form of a message of assistance to relatives or victims' families with 80% accuracy if not constrained by the network / signal on the GSM SIM900A Module.

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.
