Abstract

Food security is a strategic issue and a priority for national development in Indonesia, particularly in provinces with significant agricultural potential such as Lampung. This study aims to identify leading and potential sectors that contribute to strengthening food security by applying Location Quotient (LQ), Growth Ratio Model (GRM), Overlay Analysis, and Spatial Analysis. The LQ results indicate seven basic sectors, including food crops, agricultural services, livestock, fisheries, plantations, horticulture, and the food and beverage industry. Further analysis through GRM and Overlay shows that livestock and the food and beverage industry are categorized as leading sectors, while food crops, agricultural services, fisheries, plantations, and horticulture are identified as potential sectors. Spatial analysis highlights Central Lampung, East Lampung, South Lampung, Tulang Bawang, and North Lampung as key regions with sectoral specialization, supported by natural resources, infrastructure, and industrial networks. The findings demonstrate that Lampung Province plays a vital role as a national food barn, but challenges remain, including land conversion, productivity disparities, and post-harvest management. Therefore, integrated policies that combine sectoral revitalization, spatial planning, and sustainable management are required. This research provides a comprehensive foundation for formulating regional economic development strategies to enhance food security resilience in Lampung Province.

Abstract

This study examines the impact of the Gerakan Sumsel Mandiri Pangan (GSMP) program on regional economic growth in Southern Sumatra using a Difference-in-Differences (DiD) approach. GSMP is a flagship provincial program aimed at strengthening household food self-sufficiency and reducing dependence on social assistance. The analysis compares economic growth trends between South Sumatra Province as the treatment group and Lampung Province as the control group over the period 2019–2024. The DiD results indicate that, following the implementation of GSMP, the average growth of Gross Regional Domestic Product (GRDP) in the treatment province increased by approximately 0.024 percentage points relative to the control province. Further regression results show that food security, proxied by the Food Security Index, has a positive and statistically significant effect on GRDP, while population density exerts a negative influence. These findings imply that while GSMP contributes to improved food self-sufficiency and exhibits a positive association with economic growth, its aggregate impact on regional GRDP has not yet been sufficiently strong to generate statistically significant macroeconomic effects

Abstract

The agricultural sector occupies a pivotal position within the Indonesian economy, particularly in underpinning food sovereignty and galvanising regional economic advancement. From an Islamic economic standpoint, productive endeavours constitute an integral manifestation of earth stewardship (isti'mar al-ardh), as divinely ordained in QS. Hud: 61, and must be inexorably oriented toward the collective amelioration of societal welfare. This article aims to identify the bearing of rice cultivation output upon the Gross Regional Domestic Product (GRDP) of the agricultural sector across Indonesia in 2024. Employing a quantitative epistemological paradigm, this study draws upon secondary data procured from the Central Statistics Agency (BPS), encompassing cross-sectional observations spanning 38 provincial jurisdictions throughout Indonesia. The analytical instrumentation deployed is simple linear regression. Empirical findings corroborate that rice production exerts an affirmative and statistically consequential influence upon the agricultural sector's GRDP, evidenced by a probability value of 0.0000 (<0.05). The regression coefficient of 0.365528 denotes that an incremental augmentation in rice production is concomitantly accompanied by a commensurate ascendancy in agricultural GRDP. The coefficient of determination (R-squared) of 0.677635 substantiates that rice production explicates 67.76% of the observed variability in the agricultural sector's GRDP. Accordingly, rice cultivation output assumes an indispensable role in buttressing the operational performance of Indonesia's agricultural sector. This empirical corroboration affirms that the amplification of rice production not only catalyses macroeconomic proliferation but also resonates consonantly with the Islamic economic tenet of attaining comprehensive prosperity (falah) and overarching communal beneficence.
