Abstract

Farming in highland areas faces unique challenges such as changes in temperature, high humidity, and limited access to technology information. This community service activity aims to boost farming productivity by using the Internet of Things (IoT) for monitoring and managing agricultural land. The methods used include identifying the problems faced by farmers, designing an IoT system based on environmental sensors, and providing support and training on how to use the technology to the community. The IoT system that has been set up can monitor the temperature, air humidity, and soil moisture in real-time. This helps farmers make decisions about irrigation and taking care of their plants. The results of the activity show that there has been an improvement in how efficiently water is used, a decrease in the risk of crop failure, and an increase in agricultural production. In addition, support and technical training improve farmers' skills in using the system, making the adoption of technology more effective. Therefore, using IoT in highland farming can be a smart way to boost efficiency, productivity, and sustainability in agriculture in highland areas.

Abstract

Rumah Gadang Salo Payakumbuh is one of the Minangkabau cultural heritage sites with significant historical, philosophical, and architectural values. However, the utilization of digital media as a means of cultural documentation, education, and promotion remains limited, resulting in insufficient dissemination of its cultural values to the wider community. This community service program aimed to assist local partners in producing audiovisual media based on digital technology as an effort to preserve and promote Rumah Gadang Salo Payakumbuh. The implementation methods included field observation, partner needs assessment, creative concept development, audiovisual production training, video shooting assistance, video editing, and joint evaluation with the partners. The program integrated the expertise of the Visual Communication Design discipline in visual communication planning, cinematography, and video editing with the Computer Science discipline in multimedia technology and digital media utilization to produce informative, engaging, and accessible digital content. The primary output of this program was a cultural documentary video that serves as a medium for education, cultural tourism promotion, and digital documentation of local cultural heritage. The results indicate that the partners improved their knowledge and technical skills in audiovisual media production while obtaining a promotional medium capable of expanding public access to information about Rumah Gadang Salo through various digital platforms. This community service activity is expected to support technology-based cultural preservation, enhance community participation in safeguarding cultural heritage, and strengthen the sustainable promotion of cultural tourism destinations in Payakumbuh City.

Abstract

Customer satisfaction is a crucial indicator in assessing the service quality of a retail business, specifically at Minimarket Berkah Jaya. Currently, customer satisfaction measurement is conducted manually, resulting in subjective and unstructured data, which hinders management from evaluating and improving service quality effectively. Therefore, this study aims to apply the C4.5 algorithm to measure and classify the level of customer satisfaction. The research data were collected through questionnaires distributed to 50 customers. The classification process used the C4.5 algorithm with attributes: Cashier Service, Shop Assistant Service, Product Completeness, Transaction Speed, and Store Facilities. The algorithm constructed a decision tree based on entropy and information gain calculations. The results indicate that Cashier Service is the most influential factor in determining customer satisfaction at Minimarket Berkah Jaya. The developed system assists management in data-driven decision-making to enhance service quality.
