Abstract - This research is done because the processing of archiving is still done manually, this is very difficult and slow in searching if needed. Archiving a few months or even years ago will certainly be difficult to find because of the accumulation of files or because the archive has been damaged. The difficulty and complexity can be overcome by using WEB-based and MySql databases to manage archives. Management utilizing WEB-based and MySql databases are no longer in the form of archive sheets but have been in the form of scanned files from the original archive. The scanned archive will be stored with certain codes to make it easier to search so that the archives that came in a few months or even years ago are undamaged and easy to find.

Abstract - Face recognition is one of the important research fields and lately many applications can apply it, both in the commercial and law enforcement fields. Facial recognition techniques have now made significant progress, considering that face recognition techniques are a much-needed field of research for various fields. The face recognition application is currently being developed because it can be applied in various fields of problems such as criminal recognition, security applications, attendance, or human interaction with computers. Many methods are used in face recognition applications, one of which is the Complete Kernel Fisher Discriminant (CKFD) method which is the development of the Kernel Principal Component Analysis (PCA) method and Fisher Discriminant Analysis (FDA). The Complete Kernel Fisher Discriminant (CKFD) method has two advantages compared to the previous Kernel Fisher Discriminant (KFD). First, the implementation of this algorithm can be divided into two phases, namely Kernel principal component analysis (KPCA) plus Fisher linear discriminant analysis (FLD) so that the results are more transparent and simpler. Second, the CKFD can make two categories of discriminant information so that the results are stronger. The design of this application aims to implement face recognition systems using the Complete Kernel Fisher Discriminant (CKFD) method. The design of face image recognition application is designed using Visual Basic 2008, where this system can be used for face recognition with an average of 56.48% so the results can be said to be not very accurate. But this system needs further development, so that it can be used to recognize facial images more accurately, and increase the size and resolution of images used above 240x240 pixels.

Abstract - The purpose of this thesis is to facilitate users in managing data on raw materials and finished materials to obtain profits or profits in carrying out the production process. The current method is still manual, where there is an error in calculating the amount of raw materials needed, so that losses often occur in each production process. This application is designed using the Just In Time (JIT) method or a timely method where users will only buy raw materials according to the number of needs needed. So that users will be easier to save on production costs because they will not be afraid of excess stock of raw materials, and this will also save storage space in the warehouse. So it can be concluded that this application can replace the old method. So that in each production process it is carried out properly and gets a bigger profit or profit. The weakness of this application is that the design is still very simple.
