Media sosial yang banyak digunakan warga Desa Batulayar adalah Facebook dan Instagram. Mengenai daerah wisata, walaupun Desa Batulayar tidak memiliki daerah pantai namun Desa Batulayar memiliki pariwisata yang cukup menjanjikan yaitu Embung Teloke yang ada di Dusun Orong. Namun masih banyak masyarakat luar yang tidak mengetahui keberadaan Embung Teloke ini. Dikarenakan belum sadarnya masyarakat akan kegunaan sosial media untuk menyebarluaskan informasi daerah wisata yang mereka miliki. Sedikitnya warga masyarakat yang berperan dalam menyebarkan informasi melalui sosial media juga menjadi kendala kurang terkenalnya daerah wisata di Desa Batulayar. Dari permasalahan yang sudah dijelaskan tersebut dibutuhkan sebuah kegiatan penyuluhan yang berkaitan dengan penggunaan media sosial untuk mempromosikan daerah-daerah...

Di Indonesia, sekolah-sekolah diharuskan untuk mengubah proses pembelajaran yang lazimnya dilakukan dengan cara tatap muka secara langsung dalam sebuah kelas, menjadi pembelajaran secara daring atau pembelajaran jarak jauh untuk mencegah penularan Covid-19. Namun, proses pembelajaran daring ini mengalami kendala karena masih kurangnya pemahaman dan keterampilan guru atau tenaga pengajar dalam memilih dan mengelola media pembelajaran daring yang berbasiskan teknologi. Untuk membantu mengatasi kendala ini, maka perlu untuk dilakukan kegiatan pelatihan untuk para guru agar dapat menggunakan salah satu aplikasi yang cukup mudah dan dapat membantu proses pembelajaran daring yakni aplikasi Zoom Meeting. Kegiatan pelatihan ini dilaksanakan di salah satu SD Negeri di Kota Mataram, yaitu SD Negeri 10 Cakranegara. Metode pelatihan yang digu...

Image search using text query has a weakness because of the limited description of information stored or given by humans to the metadata on an inconsistent image that greatly affects the duration of searching an image in a database. Content based image retrieval (CBIR) is an image processing application to find the image sought in a large image database based on a query or user request. CBIR technique utilizes features that exist in images, namely color, texture, and shape. These features will be used as a basis for searching images in an image database. In this study the authors used the Haar wavelet method and histogram to look for texture and color features in the image. Then the features found are matched with features stored in the database using the Euclidian distance method. In this study the authors used the Corel dataset as research material. The dataset used is classified into ...

The aim of this method is to improve the lack of vehicle throughput (FF ) of the works called as traffic light signal parameters optimization using the MEGA and Particle Swarm Optimization (PSO). In this case, the modification of MEGA is done by adding Hash-Table for saving some best populations for accelerating the recombination process of MEGA which is shortly called as H-MEGA. The experimental results show that the H-MEGA based optimization provides better performance than MEGA and PSO based methods (improving the FF of both MEGA and PSO based optimization methods by about 10.01% (from 82,63% to 92.64%) and 6.88% (from 85.76% to 92.64%), respectively). In addition, the H-MEGA improve significantly the real FF of Ooe Toroku road network of Kumamoto City, Japan about 21.62%.

And for each person must have a genre favorite that is different from one another, but to distinguish it does not need to play music files one by one especially if the number of music files is a lot. Therefore, computer software is needed to distinguish each of these genres in order to make it easier for users to distinguish and group the types of music according to their wishes automatically. By using the MFCC and KNN methods as a classification solution to classify several types of genre streams can be easily resolved.
