Abstract

Dibalik berkembangnya teknologi yang semakin maju dan cepat, masih terdapat yang menggunakan cara tradisional dalam penyampaian informasi. Sebagai contohnya yaitu kegiatan surat menyurat seperti pembuatan surat pemberitahuan, surat undangan, atau surat edaran yang masih banyak dilakukan salah satunya pada instansi. Pada SMA Muhammadiyah 7 Surabaya, pengelolaan surat masih menggunakan cara manual dimana staf tata usaha mencatat rincian surat di buku besar kemudian menyimpan surat di lemari pengarsipan. Begitupun ketika ada surat keluar tidak selalu diarsipkan, dokumen hanya disimpan dalam komputer saja. Dengan adanya beberapa masalah tersebut maka penelitian ini bertujuan untuk membuat sistem informasi surat menyurat elektronik dengan tanda tangan digital menggunakan algoritma Rivest Shamir Adleman berbasis website untuk dapat membantu dalam mengelola surat yang ada, seperti membuat surat dan mengarsipkannya. Sistem informasi surat menyurat elektronik dirancang menggunakan metode Waterfall. Sistem ini akan dibangun menggunakan framework CodeIgniter dan pengujian menggunakan metode Black-box Testing. Dengan adanya Sistem Informasi Surat Menyurat ini bisa membantu bagian tata usaha dalam hal mengelola surat menyurat yang ada menjadi lebih mudah dan efisien. Bagian tata usaha hanya perlu mengisi data yang diperlukan saat mengarsipkan ataupun membuat surat keluar, kemudian dapat langsung ditandatangi oleh kepala sekolah secara digital jika diperlukan.

Abstract

Tomato is an important food crop in the world, including Indonesia, which often faces leaf diseases such as mosaic virus, target spot, bacterial spot, yellow leaf curl virus, late blight, leaf mold, early blight, spider mites, and septoria leaf spot. These diseases are difficult to recognize manually, so Deep Learning technology, especially Convolutional Neural Network (CNN), is used for the classification process. This research uses Inception V3 transfer learning model and image preprocessing and data augmentation. Testing is done with various optimizers (Adam, SGD, RMS Prop) to find the best model. Tests were conducted using confusion matrix to determine the level of accuracy produced by the CNN model. The results show an accuracy of 93.8% with the optimal model using Optimizer Adam.

Abstract

Universities strive to enhance public services to continually elevate user satisfaction. One critical aspect of public service is the accessibility and transparency of information, particularly in ensuring that students can easily access relevant information, contributing to heightened satisfaction with the university. However, while fostering openness and accessibility, adequate resources are essential to manage the surge in information requests from students. Chatbots emerge as a viable solution for disseminating information on academic activities, providing easy accessibility unhindered by temporal or spatial constraints at UPN "Veteran" Jawa Timur. In the initial phase of chatbot design, delineating the flow of user queries and corresponding bot responses is imperative. Questions, organized in a flow-based manner, are derived from a dataset of student queries related to academic policies. Extracting prevalent topics from both the question dataset and academic policy regulations at UPN "Veteran" Jawa Timur resulted in four overarching question topics: Implementation of Education, Learning Beyond the Study Program, Assessment and Evaluation of Learning Outcomes, and Academic Violations. The Conversational Flow Diagram is crafted based on these topics, serving as the foundational pattern for the chatbot. The test results affirm the chatbot's success in accurately presenting all designated flows, thereby furnishing users with pertinent information.

Abstract

The implementation of digitalization in organizations is needed to apply technology and provide more value to customers. However, digitization still needs to be fully maximized in manually recording book stocks to record book stocks. Printed books are recorded as incoming books, sold books are sold as outgoing books and incoming and outgoing data are matched. Publishers still use Google Sheets as the primary tool for recording available book stock. However, human error, such as writing or data entry, often leads to inaccurate book stock information. Therefore, Peneleh Publishing needed an application prototype design using usability testing to identify usability issues in UI/UX development. During usability testing, the Maze tool collects user interaction data. This study used heuristic evaluation to find and solve usability problems in book sales and stock recording applications. According to the research results, the SUS score 85.2 falls into the Very Good and Acceptable category. In addition, as shown by the Tool Maze analysis, users can manage scenarios well. Experts used heuristic evaluation to suggest display improvements, pop-up notifications when books are added or subtracted, and information about successful or unsuccessful actions.

Abstract

In the current era of modernization, almost everyone uses the internet to help solve their problems. Including security activities. Currently, many companies provide security services. There are also many companies or individuals who are or want to look for companies providing security services but they don't know where to look for these companies because of the lack of information. Therefore, to make it easier for security service seekers and security service providers, a design is needed that can be a solution to the problems of both parties. It is hoped that the required design will meet the needs because it must go through several stages of testing in accordance with standards and the needs of potential users. UI/UX analysis and design involved 10 respondents from two actors, namely companies providing security services and companies or individuals seeking security services. The final design was tested by the same 10 respondents with four types of testing. Testing is carried out repeatedly until respondents feel that the design meets the needs of potential users.
