Abstract

Micro, Small, and Medium Enterprises (MSMEs) play a crucial role in strengthening the national economy, particularly in job creation and local economic resilience. However, many MSME actors still face administrative constraints, especially in obtaining a Business Identification Number (NIB), which is a mandatory legal requirement for formal business operations through the Online Single Submission (OSS) system. Limited digital literacy and lack of understanding regarding licensing procedures often become the main obstacles. This community service activity aims to provide assistance and guidance to MSME actors in the process of registering and obtaining their Business Identification Number (NIB) through the OSS system. The implementation method consisted of socialization sessions, technical training, direct mentoring, and evaluation. Participants were guided step-by-step in preparing required documents, creating OSS accounts, and completing the NIB registration process. The activity also involved active participation from students as facilitators under academic supervision. The results showed an increase in participants’ understanding of business legality and successful issuance of NIB for assisted MSMEs. Participants demonstrated improved confidence in operating legally and accessing broader business opportunities. The implementation of this mentoring program contributes to strengthening MSME legal compliance, improving digital administrative capabilities, and supporting government programs in accelerating formalization of small businesses.

Abstract

Corn (Zea mays L.) is one of the agricultural commodities that has economic value and is widely cultivated in Indonesia. Corn productivity can decrease due to various leaf diseases, such as downy mildew, common rust, and leaf blight. Similar symptoms among these diseases make it difficult for farmers, particularly Bonanza F1 corn farmers, to accurately identify the disease and determine the appropriate treatment. The problem faced by the Food Security and Agriculture Office of Binjai City is the limited knowledge of farmers and limited access to agricultural experts in diagnosing diseases quickly and accurately. This study aims to develop an expert system to identify leaf diseases in corn plants based on the symptoms observed using the fuzzy logic sugeno method. The method involves fuzzification, inference using if–then rules, and defuzzification to produce disease diagnoses and severity levels. The test results showed that the system produced a diagnosis of Common Rust (P01) with a defuzzification value of 25.00, a confidence percentage of 33.33%, and a low severity category. Therefore, the fuzzy logic sugeno method can assist in identifying leaf diseases in corn plants more systematically and provide diagnostic information and appropriate treatment recommendations based on the available knowledge base.
