Abstract

Telah dilakukan penelitian terkait Face Recognition dengan menerapkan metode Eigenface sebagai pemicu untuk menyalakan starter mobil manual secara otomatis. Pada penelitian ini, terungkap bahwa Sistem pengenalan wajah yang dibuat memiliki tingkat keberhasilan sebesar 77% dari 13 kali pengujian pada keadaan intensitas cahaya bernilai 27 lux, dan 67% dari 15 kali pengujian pada keadaan intensitas cahaya bernilai 85 lux. Tingkat keberhasilan sebesar 75% pada keadaan sudut pencahayaan yang berbeda dengan keadaan pencahayaan data training dari 12 kali pengujian. Sistem mampu mengambil keputusan untuk wajah masukan yang tidak dikenali dengan benar dengan tingkat keberhasilan sebesar 100% dari 12 kali pengujian, dan mampu mengenali wajah dengan jarak antara camera dengan penguji berkisar 80 cm – 130 cm

Abstract

Over the past decades, practitioners and researchers have made remarkable achievements in digital forensic. The abilities to conquer major technical obstacles are bestowing practitioners greater access to digital evidence. Sophisticated forensic techniques and tools are being developed to assist forensic acquisition and extraction of volatile data, inspection of remote repositories system and analysis of network traffic. Computer forensic is a comprehensive work that based on several attributes that are : objectivity, relevance and legitimacy to compose a system model that projected to be an electronic evidence forensic system. Latest studies show that the rapid growing of cloud computing facilities usage that has enable various improvements as part of the innovation process at organisations. Information systems are in frequently exposed to various types of threats which able to trigger different types of bad consequences as more and more information stored, problems arise especially about security information technology risk aspects.

Abstract

Braking Automation system is needed to make people do their job in braking while driving. This paper aims to design and construct an electromagnetic braking automatic system that able to make car stopped before colliding a barrier by applying of the Proportional Integral Derivative (PID) method. To find out how the effective utilization of PID control on electromagnetic braking automatic will be compared with the results of braking without using PID. Determination tuning result of controller PID parameter obtained by using the trial and error methods and obtained the PID parameter values that suitable are Kp = 2.98, Ki = 0.104 and Kd = 1.35. The ultrasonic sensor used as detection the distance to a barrier. From the testing results of electromagnetic braking system with PID control more effective than with the electromagnetic braking system without PID because it can be seen from the side cessation of the car approaching set point, the results of the electromagnetic braking with PID control better than the electromagnetic braking without PID control.

Abstract

The purpose of this research is to detect whether a person has diabetes mellitus or not. In people with diabetes mellitus uncontrolled will result in a decline in the rate of saliva that results in bad breath. The system uses the sensor TGS 2602 and MQ 4. It's function is to detect the levels of Hydrogen Sulfide and Methan in a person’s breath. The decision is made by using the neural network with a backpropagation method. The result for 5 (five) tests of diabetes mellitus samples can be detected with a success rate of 80%, whereas using random samples, the test detected with detected with a success rate of 80% samples that didn’t contain diabetes mellitus. This system could provide a solution for testing if a person is suffering from diabetes mellitus

Abstract

In this study, the total dissolved solid (TDS) in water was made using conductivity sensor which the sensor works by using the principle of conductance that is the ability of the solution in delivering the electric current, so the more content of solute contained in the water the greater also the value of its conductance. The measurement results of the sensor will be compared with the next setpoint value will be used to turn on the booster pump which will do the filtering process in order to decrease the TDS water content by using RO membrane. The performance of sensor readings when first used is boosted by the time at which the system takes 3 minutes to reach a stable state, while for the whole system is influenced by the volume of water that will decrease its TDS level. The test results are presented in the form of graph of change of TDS water content over time, the difference of time required to decrease the TDS level by 15 ppm for 1 liter of water for 6 minutes, 2 liter of water for 10 minutes and for 3 liters of water for 16 minutes.

Abstract

Pada penelitian ini digunakan E-Nose yang menggunakan sensor gas TGS 2602, TGS 2620, TGS 2610, TGS 2622, dan TGS 822. Teh yang akan digunakan pada tugas akhir ini adalah teh hitam, teh hijau, teh melati, dan teh oolong. Pola data diperoleh dari pembacaan data dari aroma teh yang diujikan. Pola data tersebut lalu diolah menggunakan metode Backpropagation dengan 5 node input, 6 node hidden layer, dan 2 node output. Dari hasil pengujian yang dilakukan dapat disimpulkan bahwa alat yang digunakan dapat mendeteksi aroma teh dengan tingkat keberhasilan deteksi teh hitam 80%, teh hijau 100%, teh melati 90%, dan teh oolong 80%. Kata kunci: E-Nose, teh, backpropagation
