Abstract

Pengarsipan surat merupakan hal penting sebagai sumber informasi guna mendukung proses administrasi. Pengelolaan surat masuk dan surat keluar di Kantor Pemerintah Desa Sidowayah belum menggunakan aplikasi, yakni hanya mengandalkan pencatatan pada buku. Pengelolaan surat dengan cara penyimpanan secara manual sering mengalami kesalahan dalam penyimpanan data dan pencarian surat. Banyaknya surat masuk dan surat keluar yang diterima oleh Kantor Desa Sidowayah memerlukan aplikasi yang dapat membantu kinerja terkait surat-menyurat. Pengarsipan surat meliputi catatan surat masuk dan surat keluar yang diterima maupun yang dikirim. Oleh karena itu, sangat diperlukan adanya aplikasi pengarsipan surat yang dapat mengubah cara penyimpanan surat dengan cara mengurangi penggunaan kertas (paperless). Untuk mendukung pemerintah desa dalam rangka digitalisasi layanan kepada masyarakat, akan dibangun aplikasi untuk digitalisasi pengarsipan surat di Kantor Desa Sidowayah. Aplikasi yang dibuat merupakan aplikasi berbasis web menggunakan bahasa pemrograman PHP. XAMPP digunakan untuk menjalankan web servernya, dan MySQL untuk pengelolaan database. Aplikasi telah disosialisasikan kepada perangkat desa. Berdasarkan umpan balik dari pengguna, aplikasi dapat mudah digunakan dan memenuhi kebutuhan dalam pengarsipan surat di kantor desa.

Abstract

Umbul Siblarak is a natural tourist destination with significant tourist potential. However, limited internet access hinders promotion, service delivery, and visitor data management. This community service initiative aims to expand WiFi network access in the Umbul Siblarak tourist area to support digital promotion, cashless transactions, and increase Regional Original Income (PAD). Implementation methods include site surveys, network topology design, device installation, system configuration, and manager training. Results show an 18% increase in visitor numbers within three months of installation, a 25% increase in digital transactions by MSMEs, and increased exposure of Umbul Siblarak on social media. This program significantly contributes to strengthening the local economy through the optimization of information technology.

Abstract

The level of competition for new student admissions at tertiary institutions in the Central Java region for the last 5 years is quite high. STMIK Sinar Nusantara has also experienced the impact of competition, which can be seen through the decline in new students by an average of 20% in the last 5 years. This study aims to determine how much influence the promotional media has on the acceptance of new students. By collecting data from questionnaires that have been distributed to 69 parents of STMIK Sinar Nusantara students. Where these students entered college from batch 2015, 2016, 2017, 2018 and 2019. The promotional media studied included print media, namely posters, brochures and billboards. And electronic media, namely radio and websites, as well as other media through daily conversations. After the data is tested for validity, reliability test and classical assumption are processed to produce a regression equation. Hypothesis testing shows that the three independent variables studied, namely the print media (X1), electronic media (X2) and other media (X3) variables, have a positive effect on the dependent variable, namely New Student Admissions (Y). Through variable X1, it has a coefficient value of 0.990, which means the effectiveness of print media has a positive influence on registrant interest (Y), as well as variables X2 and X3, each of which has a coefficient value of X2 = 0.787 and X3 = 0.626.

Abstract

Image compression is a process that can reduce image size. In general, there are two types, lossless compression and loss compression. The method usually used in the JPEG standard is lossy compression, which removes some of the image information and takes advantage of the weakness in the insensitivity of the human eye in recognizing color gradations. With such large storage, data transfer or exchange is also increasingly difficult, especially data exchange using small storage areas. Tools that usually limit the size of storage for exchanging data. From the existing results using the DCT method is able to compress files up to 96%. Can be seen from the overall file average up to 74%

Abstract

The development of digital technology forces educational institutions to implement informatics learning that focuses not only on the use of tools, but also on improving computational thinking and problem-solving skills. However, informatics learning in junior high schools still faces problems, such as limitations in interactive learning materials and low student enthusiasm for programming lessons. This community service activity aims to implement coding learning using Scratch as part of an innovative effort in teaching informatics at Al Islam Junior High School. The method used is mentoring and practice-based training with a project-based learning approach. The participants were eighth-grade students from Al Islam Junior High School who were actively involved in creating animations and simple games using Scratch. The results of the activity showed that students' understanding of basic programming concepts, such as logic, command sequences, repetition, and branching, had increased. In addition, students' interest and participation in learning informatics also increased. This activity has a positive impact on the quality of informatics learning and can be an example of digital learning innovation at the junior high school level.

Abstract

Determining the ripeness level of California papaya is important for harvest decisions, sorting, distribution, and spoilage control. In practice, ripeness identification is still commonly performed visually and is therefore subjective. This study aims to develop a digital image-based classification system for California papaya ripeness using the K-Nearest Neighbor (K-NN) algorithm with Hue and Saturation features in the Hue Saturation Value (HSV) color space. The dataset consists of 90 primary images, divided into 60 training images and 30 testing images, with four ripeness classes: unripe, half-ripe, ripe, and rotten. All images were captured using a Xiaomi Mi A2 Lite smartphone and cropped to 1436 × 1000 pixels. Classification was conducted using Euclidean distance. The value of k was selected empirically through trial and error in the original study, and k = 9 was retained because it produced the most stable result on the available data while reducing the potential for class ties. The evaluation produced 22 correct predictions out of 30 test images, resulting in an accuracy of 73.33%. This revised manuscript strengthens the methodological reporting by clarifying parameter selection, documenting the data distribution and providing a literature-based comparison with alternative methods, such as Support Vector Machine (SVM) and Convolutional Neural Network (CNN). The findings suggest that K-NN with HSV features remains a feasible, low-cost baseline, although its performance should be improved through larger datasets, per-class evaluation reporting, and head-to-head comparisons on the same dataset.
