The rapid advancement of digital technology and internet communication necessitates robust information security mechanisms that not only protect message content but also conceal the existence of the communication itself. Steganography provides an effective approach by embedding secret messages within digital media, particularly digital images. This study aims to design of Steganography Application in Digital Images Using the Diversity Algorithm for Message Security. The research adopts an applied research methodology with a system design and implementation approach. The Diversity algorithm is employed to exploit variations in pixel color values for embedding message bits, resulting in a more randomized embedding pattern that is resistant to detection and analysis. The experimental results demonstrate that the proposed system is capable of embedding and extracting text messages accurately without degrading the original image information. Furthermore, the steno-image maintains high visual quality, indicating good imperceptibility of the embedded data. In conclusion, the developed application proves to be an effective and reliable solution for secure message transmission using digital image-based steganography.

Oyster mushrooms are a highly sought-after cultivated commodity due to their high economic value and relatively easy cultivation process. However, various diseases often occur during cultivation, which can reduce the quality and yield of the crop. The main problem faced by farmers is limited knowledge in quickly and accurately recognizing disease symptoms. Therefore, a system is needed to assist in the automatic diagnosis of oyster mushroom diseases. This study aims to design and build an expert system for oyster mushroom disease diagnosis using the Symmetric Probability method with the PHP programming language and a MySQL database. This system is designed to assist users in identifying the type of disease based on the symptoms experienced by oyster mushrooms. The Symmetric Probability method is used to calculate the likelihood level of a disease based on the probability value of each symptom selected by the user. The results show that the expert system is capable of providing a diagnosis of oyster mushroom diseases, along with a percentage value of the disease probability and treatment solutions. This system can facilitate farmers and cultivators in obtaining diagnostic information quickly, effectively, and efficiently without having to rely directly on experts.

Archiving is an important part of document management, especially in universities that produce theses every year as proof of students' academic abilities. The Faculty of Social Sciences at Dehasen University in Bengkulu still archives theses manually, which causes various problems such as difficulty in searching for data, the risk of losing documents, and inefficient archive management processes. Therefore, an archiving information system is needed that can store, manage, and display thesis data in a structured and easily accessible manner. This study aims to design and develop a web-based thesis data archiving information system at the Faculty of Social Sciences, Dehasen University Bengkulu. The methods used include data collection through observation and interviews, as well as system design stages using a structured development model. The result of this research is a web-based information system that can facilitate the process of archiving, searching, and managing thesis data, especially in the Communication Science Study Program. With this system, the archiving process becomes more effective and efficient compared to the manual management system that was previously used.

ANALISIS PENGGUNA TERHADAP SISTEM INFORMASI PELAPORAN KEUANGAN (SIPELUK) PADA KANTOR KECAMATAN KELAPA GADING

Sistem Informasi Pelaporan Keuangan (SIPELUK) pada Kantor Kecamatan Kelapa Gading. Penelitian ini dilatarbelakangi oleh pentingnya pemanfaatan teknologi informasi dalam mendukung transparansi, akuntabilitas, dan efisiensi pelaporan keuangan pada instansi pemerintahan. Metode penelitian yang digunakan adalah deskriptif kuantitatif dengan teknik pengumpulan data melalui kuesioner dan dokumentasi tampilan aplikasi. Sampel penelitian berjumlah lima responden yang dipilih menggunakan teknik purposive sampling berdasarkan keterlibatan langsung dalam penggunaan atau pengelolaan SIPELUK. Data dianalisis secara deskriptif dengan menghitung nilai rata-rata pada setiap indikator penilaian. Hasil penelitian menunjukkan bahwa SIPELUK memperoleh penilaian sangat baik dari pengguna, dengan rata-rata skor 5,00 pada aspek kemudahan akses, formulir input data, percepatan pelaporan, kelancaran teknis, keakuratan laporan, dukungan fitur, dan manfaat transparansi. Temuan ini menunjukkan bahwa SIPELUK mampu mendukung proses pelaporan keuangan secara lebih efektif, efisien, dan terstruktur. Meskipun pengguna tidak mengalami kendala teknis yang berarti, pengembangan sistem tetap diperlukan melalui penambahan fitur barcode, notifikasi, serta pembaruan tampilan aplikasi agar lebih optimal sesuai kebutuhan pengguna.

This study aims to design and build an Internet of Things (IoT)-based temperature control device for broiler chicken cages. The system was developed to help farmers monitor temperature and humidity in real time and control a heating device remotely through a smartphone. The hardware consists of an ESP8266 microcontroller, DHT11/DHT22 temperature and humidity sensor, relay module, 40-watt incandescent lamp as the heater, LCD 16x2 display, power supply, and supporting electronic components. The software was developed using Arduino IDE and integrated with the Blynk IoT platform for monitoring and manual control. The research method used was experimental design with black-box testing on sensor detection, data transmission, relay response, and Blynk application performance. The test results show that sensor data were received within 1.8-2.1 seconds, while commands from Blynk were received within 2.5-2.7 seconds. The relay response to the heater ranged from 1.5 to 1.9 seconds, and the Blynk display response ranged from 2.3 to 2.9 seconds. These results indicate that the proposed system works properly for real-time temperature monitoring and automatic/manual heating control in a small-scale broiler cage simulation.
