Media Pembelajaran Penurunan Sifat Melalui Persilangan Gen Berbasis Android

Sam'ani — 2026-06-10

Genetics, the science of inheritance or heredity of traits, is applied in breeding programs to produce animals or plants with superior characteristics. These superior traits can be achieved through cross-breeding selected animals or plants to obtain improved offspring. An Android-based application has been developed as a learning medium to predict the traits that will appear in the first generation of offspring, as well as in the second generation when these offspring are crossed. This application is intended for use as an educational tool for junior high school students. The system was developed using the waterfall methodology and implemented with Java and XML programming languages in the Eclipse Juno integrated development environment. Presenting the application in a mobile format is expected to increase accuracy, reduce the likelihood of errors, and decrease the time required to determine the inheritance outcomes of the input organisms

Rosmiati — 2026-05-25

Language is a fundamental means of communication that plays an essential role in society. In addition to the Indonesian language, the Indonesian nation possesses a rich diversity of regional languages that may be difficult for some communities to understand. Among these are the Dayak Ngaju and Dayak Ma’anyan languages. Currently, there is no officially published dictionary for the Dayak Ma’anyan language. Therefore, it is necessary to develop an application that incorporates local languages spoken in Palangkaraya, particularly the Dayak Ngaju and Dayak Ma’anyan languages, in order to help the community understand and learn these regional languages. The system development employed an experimental method consisting of system planning, program development, and result testing. The system was developed using the PHP programming language and a MySQL database, while Macromedia Dreamweaver was used for program design. The testing results indicate that the system is capable of translating words or sentences from Indonesian into Dayak Ngaju and Dayak Ma’anyan, from Dayak Ngaju into Dayak Ma’anyan and Indonesian, and from Dayak Ma’anyan into Dayak Ngaju and Indonesian

Pengembangan E-Pedoman Penulisan Tugas Akhir STMIK Palangkaraya Berbasis Android dan Google Sheets Sebagai Informasi Digital

Ferdiyani Haris — 2026-06-10

The rapid development of information technology has driven its integration into various aspects of daily life, including education. One example is the use of mobile devices such as cell phones for easy access to information. At STMIK Palangkaraya, writing a Final Project (TA) is a crucial stage in a student's studies. To maintain quality and consistency, each study program provides a TA writing guideline covering the format, structure, and procedures for conducting seminars and examinations. These guidelines are available in both hard copy and downloadable PDF files from the campus's official website. However, even though these guidelines are available, students often struggle to access information quickly and conveniently. The PDF format, which requires downloading, makes it difficult for those who need information instantly. Distribution of physical media also presents limitations in terms of time, cost, and reach, especially for students living outside the city. To overcome these obstacles, innovation is needed in the form of digitizing the Final Project writing guidelines and the Administrative Requirements for Seminars and Final Project Defenses. The proposed solution is the development of an Android-based e-Guidelines application connected to Google Sheets. This application allows students to access the guidelines and necessary files anytime and anywhere via their smartphones. Meanwhile, integration with Google Sheets enables real-time and collaborative information updates between students and study programs.

Penerapan Sistem Pakar Diagnosa Penyakit Tanaman Buah Naga Berbasis Web Menggunakan Metode Certainty Factor

Hotmian Sitohang — 2026-06-10

Dragon fruit plants are one of the agricultural commodities that are widely cultivated because they have a fairly high market value. However, in practice, these plants are susceptible to various types of diseases that can affect growth and crop yield. The lack of farmers' knowledge in recognizing disease symptoms early as well as limited access to experts becomes an obstacle in proper handling.

This study aims to develop a web-based expert system capable of assisting the disease diagnosis process in dragon fruit plants. This system utilizes the Certainty Factor method to process the level of confidence in a disease based on symptoms selected by the user. The system development process is carried out by compiling a knowledge base in the form of disease data, symptoms, and rules obtained from references and related experts.

The resulting application is equipped with data processing features, as well as the presentation of diagnostic results in an informative manner, including the type of disease, certainty value, and recommended treatment. System testing shows that the application is capable of providing diagnostic results that are quite accurate and consistent with expert analysis. With this system, it is expected that users, especially farmers, can more easily identify dragon fruit plant diseases independently and take faster and more appropriate treatment measures.

System testing was carried out using the black box testing method and expert validation. Based on the test results on 30 case data, the system produced an accuracy rate of 86.67% compared to expert diagnosis. The certainty factor values produced ranged from 0.6 to 0.9, indicating a medium to high level of confidence.
