Abstract

One form of artificial intelligence is the automatic detection of images. so the system can determine precisely the type of image or it can be called computer vision. Water guava fruit is a fruit that is often encountered in Indonesia, but many of the water guavas in the community are of poor quality, thus detrimental to consumers. Therefore we need a system that can detect the quality of the water guava. The Principal Component Analysis (PCA) algorithm and the k-nearest neighbor (k-NN) algorithm can be combined to do this job. PCA is an algorithm that can convert to a group of data that is initially correlated into uncorrelated data (Principal Component). The number of Principal Components generated is the same as the original data, but can be reduced to a smaller amount and is still able to represent the original data well. Meanwhile, k-NN is a method for classifying objects based on learning data that is closest to the object. The research model used in this research is a prototype, and the development tools used are UML. In making the water guava quality detection system, the MATLAB programming language is used, and the test uses the blacbox method. The result of this system is that the system is able to produce output in the form of quality classification of water guava fruit automatically.Keywords: Computer vision, PCA, k-NN

Abstract

Online tax payments are one way to speed up the tax reporting process for taxpayers. The development of the online system is still often experiencing problems, especially the accumulation of data which eventually the online system experiences obstacles that result in the payment process being hampered. Another problem that may occur is that there are still many taxpayers who do not know and understand the online system properly. The development of transaction monitoring has a weakness where the computer system connection will die if it is used continuously to monitor transactions that occur within 1 or 2 weeks depending on the temperature conditions of the system in which it is placed. Therefore, it is necessary to add the auto reboot feature. The development of internet of things (IoT)-based tax transaction monitoring will make it easier for taxpayers to pay taxes because there is a link between taxpayers and companies engaged in tax payment services so that taxpayers are no longer bothered with the matter of paying taxes. The purpose of this study is to design an IoT-based transaction monitoring method and connect transaction monitoring tools to each cash register database or server in each store. While the method used in this research is data collection, among others in the form of observation and interviews as well as system development methods which include analysis, design, implementation, operation, and system maintenance. The results obtained from the design and connectedness of the system indicate that tax transaction monitoring can be carried out continuously so that the system can make it easier for taxpayers to carry out reporting.

Abstract

The business environment requires organizations to have access to important and up-to-date information about their customers. Customers are one of the most important factors in today's business environment. Completeness, accuracy, up-to-date and customer information across all functions and parts of the organization is mandatory. Customer Relationship Management (CRM) can be an initiative to become a top priority in business, especially in terms of helping organizations identify and adapt to their customer needs, improve customer satisfaction, and retain existing customers.There are several well-known methodologies in implementing CRM, including methodology. Iris and the Six Sigma Methodology. There are several important points on which to base the comparison between the two methodologies including Critical Success Factor, Strength, Weakness and Organization. The Iris methodology emphasizes the integration of strategic aspects and CRM technology as one of the most attractive factors in the use of customer-oriented CRM but has many weaknesses such as limited consideration of Critical Success Factor (CSF), the user is not involved in the design of the CRM system, there is no indication or measures for user acceptance, and limited validation of methodologies for small and medium enterprises. The Six Sigma methodology has strong points in driving CRM implementation but there are many weaknesses such as limited consideration of CSF, limited validation of the methodology, the user is not involved in the design of the CRM system, and no indication or measurement of user acceptance of the methodology. The close link or integration between Iris and Six Sigma methodologies can be an effort to run a CRM system effectively and efficiently. This linkage will enable organizations to implement CRM from both a customer-oriented perspective that focuses on managing customer knowledge to anticipate future customer needs (TO-BE), establishes a clear pathway in CRM implementation that focuses on the successful adoption and implementation of CRM, prepares end users. order to be trained for the implementation of CRM, and determine the readiness of assessment of technology and organization in implementing CRMKeywords : CRM, Iris, Six sigma

Abstract

AbstractSubmission of goods in an agency or organization is one important component of learning operational activities that can be done directly and indirectly. In ensuring the process of carrying out work, an organization cannot be separated from the facilities and infrastructure used to support the performance of a company, agency, organization and government. There are still many organizations that procure facilities and infrastructure that still use conventional methods starting with filing letters from the process of submitting goods to the distribution of goods. This causes the procurement process to be slow. In this study using data collection methods in the form of observation, interviews and literature studies. The system development method used is the Waterfall method. The results of this study are an application program for procurement of goods ranging from the process of filing the goods to the procurement approval process that can help in minimizing errors in recording the data submission of goods. This programming application was built using the php programming language with the CodeIgniter framework and MYSQL application as a database server. With this procurement programming application, the applicant's work unit does not have to make a letter and come to the facilities and infrastructure department, but it is sufficient to open this item programming application to propose the procurement of goods and can also track the submission of goods that have been rejected or accepted. This application also provides information on the status of the submission.Keywords : Procuring, Waterfall, Infrastructure,The Application SystemAbstrakPengajuan barang dalam suatu instansi atau organisasi merupakan salah satu komponen penting yang kegiatan operasional pembelajaran yang dapat dilakukan secara langsung dan tidak langsung.

Abstract

The administrative process for the Lembaga Kursus dan Pelatihan (LKP) is important in the smooth implementation of training programs. Recording of training data that is properly archived is also a matter that needs to be considered for the smooth running of training and decision making. A LKP needs complete training program data to attract the attention of prospective trainees. Currently, the training registration process and training data recording at LKP Dotnet Computindo are still using manual recording. The information disseminated is also limited to people who are looking for and need a training place or course. Another problem is that prospective trainees find it difficult to register for training programs and find information about the type of training that will be running. On the other hand, training institution managers also experience difficulties in managing training data that support the running of the training program. Therefore we need a web-based application that can make it easier to register for training and can manage other supporting training data. In this application, software development uses the Waterfall model which is carried out in stages, and the PHP programming language. With this web-based application, it is hoped that training participants and instructors will no longer experience difficulties in finding training information that will be held at LKP Dotnet Computindo. Training managers also no longer experience difficulties in managing existing training data, so they no longer need to store data manually. Keywords : Training program, Waterfall method, training participants and teachers

Abstract

Data has a fairly important meaning, because it contains the information needed. Besides being important, the process of data exchange and storage certainly requires space and requires high costs. For this reason, data compression is an interesting topic for continuous research. The success of previous research in obtaining optimal compression, it will be more interesting, if tested on the Lossless and Lossy Compression Methods, which of the two methods results in more optimal compression. The amount of the compression ratio without the image rotation process. For regular images obtained Huffman Compression Ratio 48.7076% and Wavelet Compression 47.3888%. If we compare the compression ratio by comparing the initial file size without playback compared with the final file size after 90 degrees of playback, the ratio is 61.03%. Meanwhile, for irregular images, a ratio of 49.79% was obtained at 180 degrees of image rotation. The results of compression, both without and with rotation, Wavelet Compression is more optimal than Huffman Compression.
