Abstract

This study examines the causal relationship between road transportation infrastructure and regional economic growth in Jambi Province during 2013Q1–2024Q4. The analysis uses quarterly time-series data derived from Gross Regional Domestic Product at constant prices and the road-good-condition indicator, then applies the Augmented Dickey-Fuller test, optimal lag selection, VAR stability testing, Johansen cointegration, Granger causality, and a Vector Error Correction Model. The results indicate a one-way short-run causal pattern: economic growth Granger-causes road infrastructure, while road infrastructure does not Granger-cause economic growth. However, both variables are cointegrated, showing a long-run equilibrium relationship. The findings suggest that improvements in road quality in Jambi tend to follow expanding economic activity and fiscal capacity, whereas the economic benefits of road development are more visible in the long term than in quarterly movements.

Abstract

This study aims to analyze farmer characteristics, income levels, and the influence of price, production, land area, plant age, and farming experience on the income of oil palm farmers in Sukamaju Village. The method used was descriptive quantitative with a Cobb-Douglas production function approach. Data were obtained from 58 farmers through saturated sampling and analyzed using multiple linear regression. The results showed that all variables significantly influenced income. Production was the most dominant factor, followed by farming experience and price, which had a positive effect. Meanwhile, land area and plant age had a negative effect. The return to scale value of 0.979 indicates a condition of decreasing returns to scale, so that increased inputs do not produce proportional output. Therefore, increased efficiency in the use of production factors is needed.

Abstract

Imperfections in the market structure for perennial plantation commodities often trigger the phenomenon of asymmetric price transmission, which widens the price disparity between international exchanges and farm-gate prices. This study aims to quantitatively analyze the impact of international-domestic price disparities on the supply volume of oil palm (Cocos nucifera L.) and farmers’ supply volume decisions using the Farmer Choice Model econometric approach. Data were collected through a structured survey of 100 coconut-farming households in West Tanjung Jabung and East Tanjung Jabung Regencies, Jambi Province, and combined with time-series data on international reference prices (CNO Rotterdam CIF) for the period 2020–2025. The Heckman Two-Step Selection Model was used to address sample selection bias. In Stage 1 (Selection Equation—Probit), the study results show that price disparity has a significant negative effect on the probability of farmers participating in the formal market (β = -0.0412, p < 0.01). In Stage 2 (Outcome Equation—OLS with Inverse Mills Ratio Correction), the price disparity variable had a coefficient of -0.1854 (p < 0.01), demonstrating that a 10% increase in price disparity reduces coconut supply volume by 1.85%. The significant Inverse Mills Ratio coefficient (λ) (λ =       -0.412, p = 0.028) confirms the presence of selection bias and validates the reliability of the Heckman model. The results of this study recommend the need for institutional reforms in the supply chain, modernization of the cold chain and processing at the cooperative level, and price transparency based on digital technology to reduce the oligopsony of local collectors.

Abstract

Peningkatan volume sampah rumah tangga dan usaha kecil yang tidak diimbangi dengan sistem pengelolaan yang memadai, serta rendahnya kesadaran masyarakat dalam pemilahan dan pemanfaatan ulang sampah, berdampak langsung pada degradasi lingkungan, kesehatan masyarakat, dan keberlanjutan ekonomi lokal. Sebagai bentuk kontribusi institusi pendidikan dalam menjawab permasalahan tersebut, Fakultas Ekonomi dan Bisnis Universitas Jambi (FEB UNJA) melaksanakan kegiatan pengabdian kepada masyarakat bertajuk Daur Ulang dan Reutilisasi: Pemanfaatan Sampah Menuju Zero Waste. Kegiatan ini bertujuan untuk meningkatkan kapasitas masyarakat mitra dalam pemilahan dan daur ulang sampah melalui pendekatan partisipatif dan edukatif. Metode pelaksanaan meliputi ceramah, diskusi interaktif, dan demonstrasi praktik daur ulang serta reutilisasi sampah yang bernilai guna. Hasil kegiatan menunjukkan adanya peningkatan pengetahuan dan keterampilan masyarakat dalam mengelola sampah secara mandiri dan berkelanjutan, serta tumbuhnya inisiatif kolektif dalam penerapan perilaku hidup minim sampah. Simpulan dari kegiatan ini adalah terbentuknya kesadaran kolektif masyarakat mitra menuju penerapan konsep zero waste sebagai bagian dari upaya pelestarian lingkungan dan penguatan ekonomi lokal berbasis komunitas

Abstract

The rapid decline of Indonesia’s middle class poses a serious threat to macroeconomic stability. However, the factors driving this downward mobility at the household level remain underexplored. This study examines the socioeconomic drivers of middle-class welfare decline in Jambi Province and proposes targeted micro-level fiscal interventions. Using 2023-2024 SUSENAS microdata, the study employs a binary logistic regression to identify factors influencing welfare transitions, complemented by qualitative analysis in NVivo to formulate policy strategies. The empirical results indicate that approximately half of middle-class households experienced downward mobility. Downward mobility is significantly associated with informal-sector employment, larger household sizes, and female-headed households, whereas higher education and tertiary-sector employment provide protective effects. To address these structural vulnerabilities, this study contributes to the literature by linking household-level empirical analysis with micro-fiscal policy design. We propose targeted interventions, such as progressive micro-tax regimes, sector-specific subsidies, and conditional social transfers tailored to informal workers and large households. Future research should advance this framework by incorporating longitudinal panel data and developing dynamic policy simulation models to evaluate the long-term efficacy of these micro-fiscal instruments.
