Medicinal plants can be used as an alternative natural treatment, instead of chemical drugs. But because of too many types of plants and lack of knowledge, it will be difficult to identify these herbs. Computer assistance can be used to facilitate the identification of these herbs. This research proposes the identification of herbal plants based on leaf image using texture analysis. There are 10 types of herbal medicinal plants used in this study. The texture analysis used was GLCM by extracting contrast, correlation, energy, and homogeneity. Classification is done by KNN. The result of the experiment showed that the accuracy of identification using 9-fold cross-cross validation method was 83.33% using 9 subsets.

This study proposes a hybrid technique in securing image data that will be applied in telemedicine in future. Based on the web-based ENT diagnosis system using Virtual Hospital Server (VHS), patients are able to submit their physiological signals and multimedia data through the internet. In telemedicine system, image data need more secure to protect data patients in web. Cryptography and steganography are techniques that can be used to secure image data implementation. In this study, steganography method has been applied using hybrid between Discrete Cosine Transform (DCT) and Slantlet Transform (SLT) technique. DCT is calculated on blocks of independent pixels, a coding error causes discontinuity between blocks resulting in annoying blocking artifact. While SLT applies on entire image and offers better energy compaction compare to DCT without any blocking artifact. Furthermore, SLT splits component into numerous frequency bands called sub bands or octave bands. It is known that SLT is a better than DWT based scheme and better time localization. Weakness of DCT is eliminated by SLT that employ an improved version of the usual Discrete Wavelet Transform (DWT). Some comparison of technique is included in this study to show the capability of the hybrid SLT and DCT. Experimental results show that optimum imperceptibility is achieved.

At this time, leadership and social media are two things that cannot be separated. Social media becomes an information technology media for leaders to be able to communicate about their vision and purpose. Therefore, leaders must be able to use social media effectively in order to influence the community with what they think. There are three problems caused by leaders in social media which are classified into three types such as narcissistic, compulsive and paranoid. These three things become big problems in leadership on social media and therefore, we need the formula to solve the problems. The Johari Window method is a method that has four perspectives in developing four leadership classifications such as open leaders, blind leaders, hidden leadership, and unknown leaders. If these three types and four classifications are put together, a framework will be produced called "Leadership Intelligence (CI2) Framework", the next one will produce a formula S = W.L2, where this formula will produce wise leaders on social media. This journal is the development of the journal Developing "Framework Intelligence (CI3)" Inside Social Media Using Johari Window Methods and The Development and Implementation of Wise Netizen (E-Comment) In Indonesia. As a result, this journal will give an answer and solve the problem of an ethical leader on social media and how to decrease a hoax that can affect the leader on social media. This research will continue until it produces a CI1 formula that will combine culture and leadership into a social media formula in generating positive communication, creating a positive culture and making a big impact on society.

Koperasi Karyawan Mitra Makmur memiliki aplikasi Dekstop untuk menunjang kegiatannya. Walaupun demikian terdapat kendala dimana kurang praktisnya aplikasi berbasis desktop karena hanya dapat dibuka melalui komputer saja. Saat ini banyak anggota koperasi yang menggunakan perangkat mobile, hal ini melatarbelakangi perlunya pembuatan aplikasi berbasis mobile. Maka dibutuhkan aplikasi mobile dibutuhkan sebagai solusi untuk memudahkan akses. Karena terdapat dua macam aplikasi, maka keduanya harus diintegrasikan. Salah satu cara untuk mengintegrasikan kedua aplikasi tersebut dengan web service dan backend sebagai sistem manajemen konten pada aplikasi mobile. JSON (Javascript Object Notation) diusulkan sebagai perangkat pertukaran data. JSON dipilih karena prosesnya yang cepat dan ringan. Untuk mengukur kinerja web service pada proses integrasi, maka perlu dianalisis dan diukur kebutuhan waktu request HTTP sampai didapatkan response HTTP. Terdapat dua cara pengukuran lama waktu request web service yaitu dengan pengujian secara online dan lokal. Masing-masing pengujian request dilakukan sebanyak lima kali dimana didapat rata-rata 1192 ms. Waktu yang dibutuhkan tersebut relatif wajar dan dapat disimpulkan bahwa proses integrasi dapat berjalan dengan baik.

Radio SSFM Semarang merupakan salah satu radio yang pernah populer di Semarang. Radio ini merupakan salah satu anak perusahaan Suara Merdeka grup. Radio SSFM Semarang perlu dikembangkan kembali agar dapat bersaing dengan radio lain. Salah satu yang perlu dikembangkan adalah website radio SSFM. Website ini sebelumnya hanya digunakan untuk melakukan streaming dan dibuat dengan PHP biasa yang belum menggunakan framework sehingga akan sulit dilakukan maintenance. Penelitian ini melakukan perancangan ulang untuk membuat perubahan yang signifikan pada website, sehingga penyiaran juga dapat dilakukan dengan sistem berbasis web yang modern, kreatif dan inovatif. Framework Codeigniter dan metode Model View Controller (MVC) diusulkan untuk mengimplementasikan website SSFM Semarang. Penggunaan framework Codeigniter dan metode MVC diusulkan agar website dapat lebih mudah dipelihara, cepat, andal dan mudah diakses. Website yang telah dibangun telah diuji dengan metode black-box dan uji performa dengan pengukuran waktu load website. Hasil pengujian menunjukkan bahwa penggunaan metode MVC dapat meningkatkan performa kecepatan load website. Dengan hasil pengembangan website ini diharapkan developer tidak perlu banyak dalam melakukan perubahan kode saat melakukan maintenance karena website sudah terstruktur dengan metode MVC.

Image watermarking is one of the most popular techniques for authenticating copyright on the digital image. Many research on image watermarking has proved that the joint of Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) combinations can improve both imperceptibility and robustness when compared to DCT or DWT only. Discrete Tchebichef Transform (DTT) denotes an alternative transformation that has a similarity property with DCT. DTT has an advantage in reducing memory requirements during computing, so the calculation speed is much faster than DCT. This study tested the performance of DTT and DCT on non-blind image watermarking method, where DTT and DCT are performed after DWT. Based on the experimental results, this research proved that the DTT was combined successfully with DWT and very potential for further investigation because it has a computing performance much better than DCT. While the image watermarking quality, both the imperceptibility and robustness aspects were completely identical with the combination of DCT and DWT transformation.

Although numerous studies have been conducted on handwritten recognition, there is little and non-optimal research on Javanese script recognition due to its limitation to basic characters. Therefore, this research proposes the design of a handwritten Javanese Script recognition method based on twelve layers deep convolutional neural network (DCNN), consisting of four convolutions, two pooling, and five fully connected (FC) layers, with SoftMax classifiers. Five FC layers were proposed in this research to conduct the learning process in stages to achieve better learning outcomes. Due to the limited number of images in the Javanese script dataset, an augmentation process is needed to improve recognition performance. This method obtained 99.65% accuracy using seven types of geometric augmentation and the proposed DCNN model for 120 Javanese script character classes. It consists of 20 basic characters plus 100 others from the compound of basic and vowels characters.

Speaker recognition to recognize multiethnic speakers is an interesting research topic. Various studies involving many ethnicities require the right approach to achieve optimal model performance. The deep learning approach has been used in speaker recognition research involving many classes to achieve high accuracy results with promising results. However, multi-class and imbalanced datasets are still obstacles encountered in various studies using the deep learning method which cause overfitting and decreased accuracy. Data augmentation is an approach model used in overcoming the problem of small amounts of data and multiclass problems. This approach can improve the quality of research data according to the method applied. This study proposes a data augmentation method using pitch shifting with a deep neural network called pitch shifting data augmentation deep neural network (PSDA-DNN) to identify multiethnic Indonesian speakers. The results of the research that has been done prove that the PSDA-DNN approach is the best method in multi-ethnic speaker recognition where the accuracy reaches 99.27% and the precision, recall, F1 score is 97.60%.
