Abstract

Understanding macroeconomic dynamics in the United States requires advanced forecasting techniques capable of capturing both seasonal structures and external shocks. This study investigates the relationship between passenger flight distance and the unemployment rate through the implementation of the Seasonal Autoregressive Integrated Moving Average with Exogenous Variables (SARIMAX) model—an enhancement of the SARIMA framework. While SARIMA accounts for autoregressive, differencing, and moving average components with seasonal integration, SARIMAX further augments this structure by incorporating exogenous predictors, enhancing explanatory and predictive power. Monthly time series data from 2015 to 2024 were utilized, with flight distance as the endogenous variable and the unemployment rate as the exogenous regressor. The modeling procedure involved rigorous stationarity testing via the Augmented Dickey-Fuller (ADF) test, model selection using the Akaike Information Criterion (AIC), and residual diagnostics employing the Box–Ljung and Shapiro–Wilk tests. SARIMAX(0,1,0)(0,1,1)[12] + X emerged as the optimal specification, with all parameters statistically significant and a MAPE of 3.68%, denoting excellent forecast accuracy. Empirical findings reveal a significant and negative association between unemployment and air travel activity, emphasizing the role of labor market dynamics in shaping mobility trends. These results reinforce the utility of SARIMAX as a robust tool in macroeconomic forecasting and evidence-based policy formulation.

Abstract

Strengthening Islamic and Muhammadiyah values ​​(AIK) is an important foundation in developing religious attitudes and an Islamic work ethic within the Muhammadiyah Community Service environment. However, support staff such as office boys, drivers, and security guards at the University of Muhammadiyah Semarang (UNIMUS) often do not receive systematic guidance regarding the implementation of obligatory worship, especially the five daily prayers. This community service activity aims to increase understanding, awareness, and consistency in the practice of obligatory worship through an educational, participatory approach and the application of simple learning media. Implementation methods include socialization, andragogy-based worship practice training, the provision of short learning videos, the use of daily worship journals (printed and digital), and routine mentoring. Evaluation was carried out through pre-post tests, observation of worship practices, and participant reflections. The results of the activity showed a significant increase in the understanding and implementation of obligatory worship, reflected in increased post-test scores, regular congregational prayers, and increased spiritual commitment of support staff. In conclusion, this program is effective in strengthening the practice of obligatory worship while building a more harmonious Islamic work culture within the UNIMUS environment.

Abstract

This PKM-PM program implements the innovative Smart Composting Bin product, “Binovation,” based on the Internet of Things as an appropriate technological solution for managing household organic waste and enhancing the efficiency of community-based agribusiness. Binovation was developed as a smart composting system that integrates temperature and humidity sensors to monitor and optimize the decomposition process of organic materials in real time. The community service activities were conducted through the empowerment of the PKK group in Candisari Village, Mranggen District, Demak Regency, which faces the challenge of household organic waste dominance exceeding 60% and limited waste processing at the source level. The implementation methods included socialization activities, direct deployment of the Binovation product, IoT-based composting technical training, continuous mentoring, and evaluation using pre-test and post-test instruments. The results demonstrated that all participants (100%) were able to operate the Binovation system independently after the mentoring process. Evaluation findings indicated an improvement in participants’ understanding of organic waste management and composting technology by 35–45%. Furthermore, the implementation of Binovation reduced household organic waste volume by approximately 40% per week and produced usable organic compost within 10–20 days. Key outputs, including the Binovation product, organic compost, and enhanced technological capacity of partners, serve as indicators of program success. Overall, this PKM-PM program confirms the effectiveness of Binovation as an appropriate technological innovation supporting environmental conservation and sustainable household agribusiness.
