Abstract

Stunting is a growth problem in toddlers which is characterized by the length or height of the child being below the established standard deviation. The development of pregnant women greatly affects the health and growth of the womb. Problems with fetal development in the womb that result in low birth weight. The length of the baby is also associated with the incidence of stunting. This is also one of the causes of many toddlers experiencing stunting, because the food provided does not show what is called 4 healthy 5 perfect food. By looking at the number of stunting cases in toddlers in the community, an expert system is needed that can assist users in diagnosing stunting more quickly. This expert system research uses data collection techniques directly to the field to collect data by means of data collection techniques as follows; observations, interviews, and library studies. The use of an expert system with the Forward Chaining & Naïve Bayes method in this system can help and make it easier for users to detect stunting in toddlers.

Abstract

Mountain climbing requires high vigilance and preparedness related to various conditions that may be faced. In order to improve the safety and comfort of climbers, this research designs and builds a system for detecting ground level, air pressure and temperature as well as monitoring the health of climbers with Telegram notifications based on Arduino Mega 2560. This system uses Arduino Mega 2560 technology, a board-based micro-controller that can be programmed for various applications. The system is able to detect and monitor ground level, air pressure, temperature and climbers' health conditions in real-time. In addition, the system is also integrated with Telegram, a popular communication platform. The Telegram notification facility is used to send information and alerts from the system to climbers or support teams. Thus, preventive measures or emergency treatment can be taken immediately if there is a significant change in conditions. With the design of this system, it is expected that the safety and comfort of mountain climbers can be better guaranteed, and the risk of accidents and unwanted health conditions can be minimized. This research contributes to the development of supporting technology for safer and more comfortable mountaineering activities

Abstract

The library of SMP Negeri 22 Padang in managing library data, both member data, borrowing books, returning books to making reports, still uses paper media in recording data in the library. Rapid Application Development (RAD) this method aims to shorten the time in planning, designing, and implementing a system compared to traditional methods. The RAD method has phases viz. (1) Planning the requirements of the system, (2) design workshops, (3) implementation that involves users in designing the system. The rapid application development (RAD) method is used as a reference for developing this software and is implemented into an application program using the PHP programming language, XAMPP 3.2.1 as a MySQL- based database creation software and testing is carried out using black box techniques. The results of the development of this library information system can make it easier for library admins to ma nage library data easily, officers can carry out the process of adding borrowing and returning books in the library quickly, thus saving time in making reports.

Abstract

Tingkat kelulusan mahasiswa tepat waktu adalah ukuran penting untuk mengetahui seberapa efektif sistem pendidikan tinggi. Untuk memprediksi kelulusan siswa berdasarkan data akademik, penelitian ini menggunakan algoritma Random Forest. Penelitian ini menghasilkan model prediktif dengan menganalisis faktor seperti IPK, kehadiran, dan nilai mata kuliah inti dari dataset seribu catatan mahasiswa dari berbagai program studi. Metode pembelajaran mesin ini dipilih karena kemampuan untuk menangani data yang rumit dan membuat prediksi yang akurat. Hasil penelitian menunjukkan bahwa algoritma Hutan Random memiliki akurasi 87,5% dalam memprediksi status kelulusan siswa, serta presisi 86,3% dan recall 85,9 %. Tingkat kehadiran dan IPK adalah faktor paling penting dalam menentukan kelulusan tepat waktu, menurut analisis fitur penting. Model ini dapat membantu institusi pendidikan menemukan siswa yang berisiko tidak lulus tepat waktu, memungkinkan intervensi dini untuk meningkatkan tingkat kelulusan.

Abstract

Online marketplaces in Indonesia are growing rapidly and have become one of the main destinations for internet and social media users. Various marketplace services are available and accessed by the majority of Indonesians. However, with this development, consumer satisfaction with marketplace services varies, from positive, to negative, to neutral. Many consumers express their reactions on social media, including Twitter. In this study, an analysis of opinions was conducted on posts by online business customers in Indonesia on Twitter from various consumers. However, due to the large number of comments, it is difficult to conclude the customer's opinion about online shopping sites that offer the best services. Even trending topics on Twitter only display hot topics that are widely discussed without clear conclusions. To classify general opinion data on Twitter from e-commerce sites, the first step is to process tweet data using Rapidminer tools to recognize the tweet data. Then, the decision tree algorithm is used to categorize opinion data. The results showed that using cross-validation, the decision tree algorithm achieved an accuracy of 70.27 percent while using split validation, it achieved an accuracy of 66.95 percent. In this case, better accuracy was achieved using cross-validation. The results of this study can provide useful information for online businesses in Indonesia to improve the quality of their services and increase customer satisfaction. In addition, this study also provides an overview of the importance of utilizing the decision tree algorithm in categorizing opinion data on social media, especially on Twitter, as a tool for analyzing consumer sentiment towards a service or product.

Abstract

Basiba is an important element in traditional Minangkabau women's clothing, possessing profound philosophical value and reflecting local cultural identity. However, amidst globalization and the dominance of popular culture, the younger generation is beginning to lose touch with traditional cultural symbols, including Basiba. This community service project aims to disseminate the visual meaning of Basiba as a Minangkabau cultural identity to the younger generation through a digital media-based visual communication design approach. This topic was chosen based on the urgency of preserving local cultural values in a format relevant to media developments and the information consumption patterns of today's young generation. Partners in this activity are student and university students in Padang City who have a Minangkabau background but have minimal knowledge about the philosophy of traditional clothing. The community service method includes observation, focus group discussions (FGDs), creation of digital visual content (such as infographics, educational videos, and social media campaigns), and evaluation through questionnaire before and after the activity. The results showed an increased understanding and appreciation of the visual meaning of Basiba, as well as an increased interest in relearning other local cultural symbols. Digital media has proven effective in bridging cross-generational communication and rebuilding a lost cultural identity. This activity underscores the importance of visual strategies and digital technology in supporting the sustainable preservation of Minangkabau culture among the younger generation.

Abstract

The INKANAS Karate School of West Sumatra routinely conducts promotion tests for its karateka. However, the assessment process is still carried out manually, which risks subjectivity and inefficiency. This research aims to design a Decision Support System (DSS) based on the Weighted Sum Model (WSM) method to determine promotion eligibility more objectively and systematically. The system uses three criteria: Kihon, Kata, and Kumite, and was developed using PHP and MySQL. This DSS is expected to support a more transparent and efficient decision-making process.
