Abstract

The class imbalance is a condition when one class has a higher percentage than the other then it can affect the accuracy. One method in data mining that can be used to classification is logistic regression method. The method used in this research is RWO-sampling method using random replicate approach for synthetic data generation on descrete attribute. The result of the research can handle the problem of class imbalance, RWO-sampling method with random replicate approach shows better accuracy than RWO-sampling method with roulette and ROS approach. The accuracy value for RWO-Sampling method with roulette and RWO-Sampling approach with random replicate approach has increased to an average of 15.55% of each dataset. As for comparithem with the ROS method has increased an average of 3.7% of each dataset. Furthermore, for testing the underfitting problem in logistic regression, the oversampling method is better than non-oversampling with an increase in accuracy value reaching an average of 2.3% of each dataset.

Abstract

The main problem in producing high accuracy software defect prediction is if the data set has an imbalance class and dichotomous characteristics. The imbalanced class problem can be solved using a data level approach, such as resampling methods. While the problem of software defects predicting if the data set has dichotomous characteristics can be approached using the classification method. This study aimed to analyze the performance of the proposed software defect prediction method to identify the best combination of resampling methods with the appropriate classification method to provide the highest accuracy. The combination of the proposed methods first is the resampling process using oversampling, under-sampling, or hybrid methods. The second process uses the classification method, namely the Support Vector Machine (SVM) algorithm and the Logistic Regression (LR) algorithm. The proposed, tested model uses five NASA MDP data sets with the same number attributes of 37. Based on the t-test, the < = 0.0344 < 0.05 and the > = 3.1524 > 2.7765 which indicates that the combination of the proposed methods is suitable for classifying imbalanced class. The performance of the classification algorithm has also improved with the use of the resampling process. The average increase in AUC values using the resampling in the SVM algorithm is 17.19%, and the LR algorithm is at 7.26% compared to without the resampling process. Combining the three resampling methods with the SVM algorithm and the LR algorithm shows that the best combining method is the oversampling method with the SVM algorithm to software defects prediction in imbalanced class with an average accuracy value of 84.02% and AUC 91.65%.

Abstract

Data dari BPS menunjukkan masih sangat sedikit usaha yang memanfaatkan pemasaran online. Berdasarkan wawancara singkat dengan para pelaku usaha anggota OK oCE ADMA diketahui bahwa banyak UMKM yang terdampak selama pandemi COVID-19. Penjualan mereka mengalami penurunan selama pandemi berlangsung, karena mereka tidak dapat membuka usaha secara offline akibat adanya pembatasan sosial berskala besar. Selama ini usaha yang mereka jalan mayoritas masih mengandalkan pemasaran secara offline. Penggunaan media sosial sebagai sarana promosi pun belum dimaksimalkan dengan baik. Metode yang digunakan adalah penyuluhan sekaligus praktek pembuatan Whatsapp Bisnis. Dari hasil penyuluhan yang dilaksanakan oleh pengabdi, pelaku bisnis telah memiliki Whatsapp Bisnis bagi usaha mereka masing-masing. Namun pelaku bisnis perlu melengkapi pembuatan katalog untuk sarana pemasaran online produk mereka

Abstract

Banyubiru Tourism Village has a market potential that is able to attract tourists to come to the Merapi Valley Tradition Market. The market sells a variety of traditional specialties, traditional souvenirs, traditional utensils, and so on. However, in the promotional activities of this tourist village, it is still conventional and has not been touched by digital promotions, either in the form of websites or social media. This is the background for the community service program to create a website for the Merapi Valley Tradition Market in Banyubiru Tourism Village, Dukun District, Magelang Regency. The activity of making this website began with observations of the Head of RW, Head of RT and local residents to collect information about the Merapi Valley Traditional Market. After the website content components have been sufficient, proceed with the design and content of the Merapi Valley Traditional Market website. Furthermore, the implementation of website creation begins with the preparation of hosting and domains as well as the addition of SSL for website security. These components are needed so that the website can be accessed online by anyone who needs information. Hosting is a service for storing data, images, and files on a website. Domain is the website address. Additional security features SSL (Secure Socket Layer) is required to provide encryption security on the website. The process after implementation, namely uploading the website to the hosting that has been provided. The last is the handover of the website to the Management of the Merapi Valley Traditional Market. Making this website aims to make it easier for the wider community, both domestic and foreign tourists to get information about the cultural diversity in the Banyubiru Tourism Village, especially the culture in the Merapi Valley Tradition Market.

Abstract

D.K.I Jakarta is often called the window of Indonesia. As one of the largest cities in Indonesia, D.K.I Jakarta has various kinds of complex social problems. This research tries to identify and explore conditions of religious harmony in DKI Jakarta. In previous studies of religious harmony, the use of the index in assessing religious harmony could only describe the condition of religious harmony in general without indicating which factor was in measuring the level of religious harmony. This Research uses a clustering approach to analyse religious harmony in DKI Jakarta. The study found that cluster 0 has major problems that affect religious harmony compared to other clusters. Therefore, local government policies related to increasing religious harmony can be focused more on cluster 0, especially on variables that are shown to be low, namely empathy, non-violence, national commitment, and adaptability to local culture.
