This study analyzes the impact of MICE (Meeting, Incentive, Convention, Exhibition) factors on the economic growth of the Toba Caldera Geopark tourism destination. To support the economic growth of the Geopark, it is essential to have robust infrastructure, including adequate accessibility, convention centers with quality accommodation options, three to five-star hotels, attractive destinations with numerous facilities, parking areas, and skilled local PCOs (Professional Conference Organizers). The research background highlights issues related to the impact of MICE factors on the economic development of tourism destinations. Besides infrastructure, the products offered must have value and can be packaged to provide added value. This includes not only competitive pricing but also packaging and the product's connection to the local environment. Data collection methods used in this research include observation and questionnaires. Informants comprised various stakeholders in the MICE industry, such as the Medan City Tourism Office, event organizers, and businesses involved in tourism, including hotels, restaurants, ATMs, money changers, travel agencies, souvenir shops, transportation providers, guides, meeting organizers, congress organizers, and incentive travel organizers. The results show that accessibility does not have a direct and significant impact on the economic growth of the Toba Caldera Geopark tourism destination. Similarly, accommodation facilities do not directly and significantly influence economic growth. However, information has a positive and significant impact on the economic growth of the Toba Caldera Geopark tourism destination.

Perum BULOG Regional Division of North Sumatra faces challenges in determining optimal rice stock levels due to uncertainties in supply and distribution. The purpose of this study is to optimize rice stock management by comparing two fuzzy inference methods—Fuzzy-Sugeno and Fuzzy-Mamdani in predicting monthly rice stock levels. The method used involves analyzing rice inflow, distribution, and stock data from January to December, applying each fuzzy method using the MATLAB 6.1 Fuzzy Toolbox. The Fuzzy-Sugeno model is implemented with rule-based systems whose outputs are expressed as linear functions of the input variables and defuzzified using the weighted average method. The Fuzzy-Mamdani model applies linguistic rules with fuzzy output sets and uses the centroid method for defuzzification. The results show that both methods can optimize stock estimation, but in different ways: Fuzzy-Sugeno produces dynamic predictions that closely follow monthly operational changes, making it suitable for short-term adaptive optimization, while Fuzzy-Mamdani yields more stable predictions, supporting long-term stock stability optimization. This finding provides a practical decision-support reference for BULOG to select the method that best aligns with operational goals, thereby improving rice stock management and distribution efficiency in North Sumatra.

Purpose: This study develops the concept of ghost demography, referring to a demographic condition in which repeated automation-driven disruption gradually produces structurally detached population segments from productive labor market participation. This study aims to explain how technological change, beyond short-term job displacement, may accumulate into long-term socioeconomic exclusion at the population level. Research Methodology: An exploratory sequential mixed-method design was applied. The qualitative phase involved expert interviews to identify the mechanisms linking automation and exclusion. These insights inform the quantitative phase, which tests the relationships using cross-country labor market and digital economy indicators across 60 country sector observations from international data sets. Results: The findings reveal three interrelated mechanisms underlying the emergence of ghost demography: economic obsolescence, structural adaptation barriers driven by skill mismatch and digital inequality, and cumulative socioeconomic detachment. Regression analysis indicates that automation exposure significantly increases socioeconomic exclusion. Skill mismatch and digital inequality further intensify this relationship, whereas Institutional Quality moderates the effect by reducing the exclusionary impact of automation. Conclusions: Automation may progressively reshape labor participation patterns and generate early demographic signatures of exclusion. Limitations: The analysis relies on aggregated country sector indicators and does not fully capture individual-level labor mobility dynamics. Contributions: This study contributes to the literature on automation and labor markets by conceptualizing technological exclusion as a demographic transformation process.

Traffic violations by motorcyclists are a major contributor to accidents in Medan City. This research sought to examine the frequency of violations and the factors affecting the likelihood of such violations among riders at three intersections in Medan City: Dr. Mansyur, Setia Budi, and Fly Over Jamin Ginting. A cross-sectional quantitative design and time-based sampling was used. Observations were conducted over three days in two sessions (daytime 02:00–03:00 PM and afternoon 04:00–05:00 PM WIB), with a sample of 540 motorcyclists. The dependent variable was violation status; independent variables included gender, motorcycle type, rider status, and observation time. Binary logistic regression was applied. Results showed a violation rate of . Simultaneously, all independent variables had a significant effect (p<0.001). Partially, only rider status was significant (p<0.001; OR=2.728), meaning riders with a passenger were 2.789 times more likely to violate than solo riders. Gender, motorcycle type, and observation time were not significant. The model fitted well (Hosmer–Lemeshow test, ). In conclusion, rider status is the main factor, so supervision should focus on riders with passengers.
