Abstract

Gestur merupakan salah satu jenis komunikasi dengan membentuk suatu objek seperti huruf atau angka pada tangan untuk menyampaikan pesan ataupun sebuah informasi, salah satunya gestur angka pada tangan yang memiliki banyak jenisnya dengan pola yang berbeda untuk setiap pergerakan angka yang terbentuk. Salah satu solusi yang dapat dilakukan untuk melakukan pengenalan gestur angka pada tangan kepada komputer adalah menggunakan metode Convolutional Neural Network (CNN) dengan arsitektur AlexNet maupun LeNet. Penelitian ini menggunakan dataset citra gestur angka yang sebelumnya dilakukan tahap pre-processing yang terdiri dari threshold dan resize. Penelitian dilakukan menggunakan 2 pooling layer, yaitu Average Pooling dan Max Pooling kemudian menggunakan optimizer, yaitu SGD, RMSprop, dan Adam. Berdasarkan hasil pengujian yang didapatkan pada penelitian ini, yaitu penggunaan arsitektur AlexNet dengan Average Pooling dan optimizer RMSprop menghasilkan akuras dan f1-score keseluruhan 99,45% serta penggunaan arsitektur LeNet dengan Average Pooling dan optimizer RMSprop menghasilkan akurasi dan f1-score keseluruhan 99,49%. Secara keseluruhan penggunaan Average Pooling dengan optimizer RMSprop mendapatkan tingkat akurasi yang paling baik dibandingkan dengan pengujian yang lainnya.

The writer focused on banking company that listed in BEI (Bursa Efek Indonesia) at periode 2007-2009. The writer took variable Earnings Per Share as profit indicator, variable Loan to Deposit Ratio as liquidity indicator and Cash Flow from Operating Activity as company’s performance indicator. The objective in this study is to determine the influence of Earnings Per Share , Loan to Deposit Ratio and Cash Flow from Operating Activity on Stock Price both it partially or simultaneusly. This study used hypotesis test and the data processed by Statistical Package for the Social Sciences (SPSS) program with regression test. The result of this study partially shows that Earnings Per Share and Loan to Deposit Ratio have significant influence to Stock Price, meanwhile Cash Flow from Operating Activity has no significant effect to Stock Price. Simultaneusly, Earnings Per Share , Loan to Deposit Ratio and Cash Flow from Operating Activity have significant influence to Stock Price. Keywords : Earnings Per Share , Loan to Deposit Ratio, Cash Flow from Operating Activity and Stock Price

Technological developments have brought many changes, especially in the way we interact and do business. Currently, social media is widely used as a marketing platform for MSME products, this is because through social media the dissemination of information occurs quickly and it also allows MSME players to communicate with consumers directly and promote their products at relatively low costs. However, there are still many MSME actors who have not optimally utilized social media, such as dredged fish MSME actors in Air Jukung sub-district who only use Facebook to market their products. Because of this, the aim of this service is to provide assistance and direct practice in using social media to MSMEs in dredging fish in Air Jukung sub-district in optimizing marketing strategies in an interesting and unique way. The method for this service is in the form of training in making unique posters through the Canva application and interesting content on social media and processing it to attract consumer interest. The results of the service activities ran smoothly and received a positive response from social media users.
