Abstract

User behaviour management and analysis is very important in business. A good marketing strategy needs to be done so that the loyalty of old users is maintained. This can be initiated by segmenting users so that a good marketing strategy can be formulated. Customer segmentation can be done with the help of one of the data mining methods,  which is clustering. In this study, k-medoids algorithm is used to cluster e-ujian.com users based on the behavioral data of each user. The first step will be analyzing data attributes that can be used. Next, the clustering process was carried out with the experimentally determined value of k. Finally, the cluster results will be evaluated using the Davies Bouldin Index (DBI) to determine the best number of clusters. The results showed that the value of k = 4 became the optimal number of clusters with a DBI value of 3,017.

Abstract

Plants are one of the living things that can grow anywhere, whether it's in the home environment, yard or garden, and even though the forest. Characteristics of plants are distinguished by type, namely, Trees, Medicinal Plants, Ornamental Plants, and Grass. Toga plant is a plant that functions for the treatment of diseases. While ornamental plants are plants that function to create beauty and attractiveness. The many benefits of plants, this further increases public interest. However, when people want to plant plants but do not understand what plants are suitable, a decision support system is made to assist in determining the types of plants that are suitable and at the same time determine the level of interest of the society based on five criteria, namely price, treatment method, quality, weather, and soil conditions. By using the calculation of the Analytical Hierarchy Process (AHP) method, the calculation is carried out by determining the pairwise comparison table, normalizing the pairwise comparison matrix and calculating the weight of each criterion. The results for the Toga plant, namely Pandan, were in first place with the highest weight value of 0.337692572 while for Ornamental plants, Aglonema was in first place with the highest weight value of 0.225819915.

Abstract

The ventilator must be able to supply oxygen according to the duration and amount required, not more or less. To produce the expected oxygen levels, air pressure and air flow, all these stages and processes are controlled electronically through software. However, in its development, the software to control ventilator often encounter delay problems. One of them is related to the work of the alarm. Therefore, futher investigation is needed to reduce the delay. In this research, thread concept approach is proposed.  In this approach, the synchronous process is pushed to an asynchronous thread with a non-blocking process, in which the main running process is not blocked. As a result, the delay time decreased significantly, by 98.24% on the average value

Abstract

Errors in identifying diseases in rice plants can cause the potential for crop failure to increase by 18-80%, according to data from the Indonesian Ministry of Agriculture. This could be due to the lack of expertise in agriculture when compared to the amount of land in Indonesia. Recent research in the field of deep learning using neural networks has achieved remarkable improvements. Research on the identification of plant diseases in rice plants, using the MobileNet, NasNet and SqueezeNet architecture that supports mobile devices has been carried out. The experimental results show that the proposed architecture can achieve an accuracy of 93.3%. Motivated by previous research, this research will use DenseNet architecture (Dense Convolutional Network) to detect diseases in rice plants. The dataset used is relatively small, between 100-200 photos for each disease. To cover the lack of dataset augmentation is done to the dataset. The final results obtained are quite satisfactory with an accuracy of 96% with a Weighted Average of 97%.

Abstract

The Lubuk Raja Police and the Resort Police have functions, one of which is the Integrated Police Service Center (SPKT) whose role is to provide public services in the form of reporting from the community. In receiving reports from the public as well as when processing data, the SPKT Lubuk Raja Police officers still do it manually, such as when the officers make reports still using Microsoft Office, this can result in the accumulation of report files and make typing repeated every time there is a report from the public. In addition, there is still a manual for giving the register number and the process of recording the reporting data. Then, through a study at the Lubuk Raja Police at the Integrated Police Service Center (SPKT), the author thought about designing and creating a website-based information system. The system development method that the author uses in this study is the Waterfall Model which includes the steps of analyzing system requirements for code writing system design, testing, implementation, and maintenance. The "Software" software used in the creation of an integrated police service center information system (SPKT), such as: XAMPP (a "localhost" web server), MySQL (a SQL database management), Sublime text (as an editor, where we write program code) ). The final point of this research is the creation of an integrated police center information system (SPKT) to replace reporting, processing, and recording data, which previously used manual methods. With this, it will make it easier for members of the police to provide services to the community in the OKU police area

Abstract

Stikes Santa Elisabeth is an institution in the field of education, especially health. Stikes Santa Elisabeth has many students who come from various regions where many students have difficulty paying tuition due to economic problems. Therefore, many agencies or companies cooperate with Stikes Santa Elisabeth to provide assistance to underprivileged students such as love, single tuition fees (UKT), and the Eka Tjita Foundation. The provision of assistance certainly has rules that must be met by students. Because of the many rules or criteria that must be checked to determine which students will receive assistance, it can often result in the wrong choice as there is a limit to the number of recipients. To overcome these problems, a Decision Support System (DSS) is needed in determining the provision of assistance to students. By applying the PSI method, Stikes Santa Elisabeth can be considered to provide information about the requirements that must be met in receiving assistance. Thus helping Stikes Santa Elisabeth to determine the provision of assistance to students. This study aims to analyze the problems that occur in determining the priority of providing assistance to Stikes Santa Elisabeth students by applying the PSI method based on alternative data and predetermined criteria. Based on the ranking table above, the student who is most prioritized to get a scholarship is Irene Permatasari with a preference selection index value of 0.8765. So it can be concluded that the application of the PSI method results in a ranking so that it can help Stikes Santa Elisabeth to choose students who are the most prioritized in receiving scholarships.
