PENGGUNAAN MODEL HIDDEN MARKOV DAN METODE NEURAL NETWORK SEBAGAI PENERAPAN TEKNOLOGI PENGENALAN WAJAH

The human face recognition system is one of the fields that is quite developed at this time, where applications can be applied in the field of security (security system) such as permission to access room, surveillance (surveillance), as well as the search for individual identities in the police database. The face recognition approach aims to detect faces in 2-dimensional images and sequential images of videos that have many methods such as local, global, and hybrid approaches. Hidden Model Markov (HMM) is another promising method that works well for images with different lighting variations, facial expressions, and orientations. HMM is a set of statistical models used to characterize signal properties. An artificial neural network-based approach is learned from image examples and relies on techniques from machine learning to find relevant facial image characteristics. The characteristics studied were in the form of discriminant functions (ie non-linear decision surfaces), then used for face recognition. In this study there will be an application to compare Hidden Markov Models and Neural Network Method as a Face Recognition Technology Algorithm Model.

Implementasi Steganografi LSB Dengan Enkripsi Vigenere Cipher Pada Citra

Message encoding is an art and science to maintain news or data, learn mathematical techniques related to aspects of information security such as data confidentiality, data validity, data integrity, and data authentication. The process of encoding and inserting messages with the Vigenere Cipher and LSB methods is the first step in inputting text and keyword files, then text files and keywords are converted into decimal numbers, then processed according to the Vigenere Cipher formula, the ciphertext is then transformed into binary form it is inserted into the image by means of each bit of the ciphertext in the last bit of the image, so it is expected that the data sent is not easy to read by third parties. The vigenere cipher algorithm and the LSB (Last Significant Bit) technique can be used as a solution for the security of secret messages that are inserted into the image, can be re-revealed exactly the same as the original form and do not experience the slightest damage.

Pemodelan Direct Quadrate (D-Q) Pada Kendali Kecepatan Motor Induksi Tiga Phasa dengan Field Oriented Control (FOC) Berbasis Kendali P-I

The utilization of a 3 phase induction motor is increasingly developing, so research on speed regulation in 3 phase induction motors is also increasingly widely studied. This is because the use of 3 phase induction motors in the industry and especially hybrid vehicles are increasingly being developed. But there are some disadvantages of induction motors, one of which is the characteristics of non-linear parameters, especially rotor resistance which has varying values for different operating conditions, so it cannot maintain its speed constantly if there is a change in load. This, of course, can affect the performance of an induction motor. To get a constant speed and better system performance on load changes a controller is needed. This study aims to model direct-quadrate parameters (D-Q) using the Field Oriented Control (FOC) method based on the Proportional-Integral (PI) controller. With the d-q parameter controlled, the induction motor will be more stable, because the d-q parameter determines the stability of the change in torque and flux in the induction motor. Proportional-Integral (PI) control used is a classic control system that is easy because it does not need to look for a mathematical model of the system, but it remains effective because it has a fairly stable system response, by setting the best combination of proportional (Kp) constants and Integrator constants ( Ki). In the results of the implementation, it can be seen that the use of FOC can be used as an approach in terms of setting the speed of the induction motor, and with the use of the PI control can help the output response get better with a shorter response time to reach the reference value.

Sistem Pendukung Keputusan Penerimaan Bantuan Beras Miskin Menggunakan Metode AHP (Analytical Hierarchy Process) Pada Kecamatan Banawa

The rice program for poor families or commonly known as Raskin is one of the government's efforts to reduce the burden of expenditure on poor families. The Raskin program is to reduce poverty and maintain the food of economically disadvantaged people so that all parties are expected to participate in the success of this program so that it can be implemented properly and is beneficial to the community. In general, the problems that occur in the assistance of Poor Rice assistance are still not optimal, because at the time of selection of poor rice recipients there is no system that supports so that during the selection process still using estimates only and there is no calculation at the time of selection of poor rice recipients. So that few or many people sometimes protest because people are supposed to get help but they don't get the assistance, and vice versa. The purpose of this study is to help the committee to receive poor rice assistance in selecting people who are entitled to receive assistance, especially in the district of Banawa. The research method used is the software development method using the prototype method and decision-making method using the AHP (Analytical Hierarchy Process) method. Based on the results of testing conducted with the black box technique, the results show that the decision support system for receiving poor rice assistance can help the sub-district, especially the committee in selecting poor rice aid recipients, by comparing the criteria for each alternative and showing the value the highest of alternatives means that the alternative is the main choice for receiving poor rice assistance.
