Abstract

The food estate program is a governmental initiative designed to facilitate the integrated development of food systems within a designated area, including agriculture, plantations, and animal husbandry. The objective of the present study is first to identify the most suitable agricultural crop according to local determining characteristics; and second, to evaluate the land's suitability for each chosen agricultural crop. This study employed a combination of qualitative and quantitative methodologies. The qualitative study focused on the identification and analysis of the criteria used for the selection of suitable food estate locations and the determination of promising commodities within the study area. This was achieved through a series of focus group discussions (FGDs). Three FGDs were conducted with participants comprising provincial and regency-level government decision-makers and experts from local universities. Their insights contribute to the formulation and refinement of the selection indicators relevant to local conditions. The quantitative study employed the Analytical Hierarchy Process (AHP), enabling a systematic evaluation of expert priorities. To assess and rank the importance of key criteria influencing location selection decisions, eleven experts were interviewed. The AHP results have identified seven main criteria as being essential for determining the suitable locations for food estates in Purbalingga Regency. Pineapple has been identified as the most suitable, promising commodity for food estate development in Purbalingga Regency, as determined by the integrated assessment. This determination is based on the compatibility of pineapple with local environmental conditions, its market potential, and stakeholder preferences.

Abstract

Land-use planning and regenerative agriculture are increasingly recognised as complementary strategies for addressing declining soil quality, land degradation, and the need for more resilient food systems. The present study investigates the manner in which the integration of regenerative practices within land-use planning frameworks contributes to sustainable agricultural productivity and ecosystem stability. A bibliometric analysis of 70 publications from 2015–2025 using VOSviewer has identified key thematic clusters, including climate–resilience, sustainable productivity, spatial governance, green infrastructure, and environmental monitoring. The findings show that regenerative practices, such as no-till systems, cover cropping, diversified rotations, and agroforestry, support soil restoration, carbon accumulation, and water retention. Land-use planning provides the spatial, institutional, and regulatory mechanisms needed to align these practices with land suitability, environmental carrying capacity, and regional planning objectives. Evidence from marginal lands (S2 and S3) highlights the effectiveness of regenerative methods in enhancing productivity when integrated with suitability assessments and long-term planning. A case study of Brazil’s Carbon Farming Initiative demonstrates how coordinated land-use policies, spatial data, and public–private partnerships can scale regenerative systems and reduce greenhouse gas emissions. The analysis further shows that this integration supports multiple Sustainable Development Goals, particularly those related to food security, clean water, climate action, and terrestrial ecosystem conservation. Key barriers, including policy fragmentation, limited farmer adoption, and technological constraints, are addressed through recommendations involving financial incentives, farmer training, geospatial monitoring, and precision agriculture tools. The study provides a comprehensive understanding of how land-use planning can operationalise regenerative agricultural strategies to enhance landscape resilience, improve resource efficiency, and strengthen long-term sustainability across agricultural regions.

Abstract

Rapid land-use change in upland watersheds alters hydrological processes and increases drought vulnerability. The Upper Brantas and Kali Konto sub-watersheds in East Java serve as important rainfall catchment and water storage areas, yet ongoing land conversion has progressively reduced their capacity to regulate water availability. However, the implications of future land-use trajectories for drought hazards at the sub-catchment scale remain insufficiently understood. This study aims to analyze land-use dynamics, simulate future land-use change, and evaluate alternative land-use planning scenarios to assess their potential influence on drought hazard distribution. Multi-temporal land-use data from 2017, 2019, 2021, and 2025 were analyzed using remote sensing, and future land-use patterns were projected for 2030 using the Artificial Neural Network–Cellular Automata–Markov (ANN–CA–Markov) model. The simulated land-use distribution was then evaluated under Regional Spatial Planning (RSP) and Land Capability Classification (LCC) scenarios to examine their implications for drought hazards. The results showed a substantial decline in natural forest from 12,600.35 ha (31.4%) in 2017 to 9,975.70 ha (24.9%) in 2025—a reduction of more than 20%—accompanied by the expansion of plantation systems, dryland farming, and built-up areas. Under the 2030 Business-as-Usual (BAU) scenario, moderate drought hazard areas increased from 44.0% to approximately 50.2% of the watershed area. Among the evaluated scenarios, the Land Capability Classification (LCC)-based planning approach showed the greatest potential to mitigate drought risk, reducing high drought hazard areas from 25.1% under the BAU scenario to 15.2%. These findings highlight the importance of integrating land capability considerations into spatial planning to support drought-resilient watershed management.

Abstract

The Bangsal Sub-watershed is located downstream of the greater Brantas Watershed. It is experiencing problems primarily with poor vegetation cover and high erosion rates. This study aimed to evaluate land capability classes based on land damage status across different land uses. Sampling was carried out purposively at 15 points across five land uses, namely, forests, plantations, dry fields, rice fields and shrublands. The parameters analyzed included the physical, chemical and biological properties of soil. Land capability assessment was conducted based on Arsyad’s work (2010), while damage status was based on the Government Regulation No. 150 of 2000 and the Ministry of Environment Regulation No. 07 of 2006. The results show that the Bangsal Sub-watershed is dominated by land capability classes III to IV with moderate damage status (R.II). Fourteen observation points show moderate damage, and one shows severe damage. The main limiting factors found include porosity, redox potential and permeability. Forest and shrubland land uses show the most stable conditions in terms of all three aforesaid limiting factors. Meanwhile, dry field land use has the most complex limiting factors, including slope, surface rockiness, bulk density, porosity and redox potential. These findings emphasize the importance of matching land use to land capacity to prevent further degradation. Management recommendations include increasing organic matter to improve soil structure, applying contour terraces on sloping terrain to reduce runoff and erosion and developing agroforestry systems to improve soil stability and support watershed sustainability.

Abstract

Although Arabica coffee prices may be favorable in certain periods, increased production during peak harvest seasons can create excess supply and expose farmers to price declines, particularly when farmers rely mainly on selling coffee cherries or green beans with limited value addition. Therefore, downstream processing is needed to capture higher added value and reduce farmers’ vulnerability to market volatility. This study aims to analyze the added value generated from Arabica coffee processing and map the business model adaptation of farmer groups in Trawas District, Mojokerto Regency, East Java Province. The study was conducted from January to June 2023 using a mixed-methods approach that combined quantitative value-added analysis with qualitative Business Model Canvas mapping. The Hayami method was used to calculate value added, while interviews, field observations, and focus group discussions identified business model components and development strategies. The results show that processing red coffee cherries into green beans generated an added value of IDR 4,975.00/kg with a value-added ratio of 39.48%, indicating a moderate level of value creation. In contrast, processing green beans into ground coffee generated a much higher added value of IDR 102,250.00/kg with a value-added ratio of 90.88%, indicating a high level of value creation. These findings demonstrate that downstream processing into ground coffee provides substantially greater economic benefits than green bean processing. Practically, farmer groups need to strengthen processing capacity, product quality control, packaging, branding, digital marketing, and institutional partnerships to capture higher value and reduce vulnerability to price fluctuations caused by excess supply during peak harvest periods.

Abstract

Corn flour holds a potential for functional food through chemical and thermal modification. This study examines the impact of dual modification—organic acid esterification (using citric, acetic, or lactic acid) followed by annealing—on the physicochemical and morphological properties of corn flour. Citric acid treatment, combined with annealing, yielded the lowest swelling power and the highest clarity, indicating improved stability and transparency. Acetic acid modification produced the highest RS values, suggesting strong applicability in functional food development. The increase in RS content implies potential health benefits such as glycemic control and gut microbiota modulation, making the modified flour suitable for preventive nutrition applications

Abstract

Abstract. Hotong (Setaria italica) has promising potential as a functional food ingredient, but its native flour requires technological enhancement for broader utilization. This study evaluated the effects of solid-state fermentation using Lactobacillus plantarum, Saccharomyces cerevisiae, and their combination for 24, 48, and 72 h on the physicochemical and functional properties of hotong flour. Fermentation significantly improved flour characteristics, with outcomes strongly influenced by microbial type and duration. L. plantarum at 72 h produced flour with the highest water-holding capacity and brightness, indicating suitability for products requiring high water-holding capacity and light color. In contrast, S. cerevisiae and mixed cultures enhanced antioxidant activity, while short-term L. plantarum fermentation better preserved phenolic content. These findings demonstrate that targeted fermentation conditions can be strategically selected to produce hotong flour with characteristics optimized for specific food applications, supporting its potential development as a versatile functional ingredient.

Abstract

Conventional Red-Green-Blue (RGB) unmanned aerial vehicle (UAV) imagery offers a cost-effective alternative for precision agriculture; however, its limited spectral separability constrains classification when target classes exhibit high visual similarity, particularly in non-cultivated areas with dense vegetation. Maturity assessment of sago palm (Metroxylon sagu Rottb.) exemplifies this challenge: identification of the harvestable stage remains dependent on labour-intensive field inspection, and delayed identification causes stem mortality and yield loss. This study evaluates an Object-Based Image Analysis (OBIA) framework for discriminating three sago maturity levels (Young, Harvestable, Overripe) from RGB orthomosaics and a Digital Surface Model over a 9-hectare non-cultivated site in Wailawi, North Luwu, Indonesia, using a DJI Phantom 4 Pro at 50 m altitude. Multi-resolution segmentation generated 6,210 crown-level objects, classified by Random Forest under two configurations: a five-feature set and a seventeen-feature set optimised through Recursive Feature Elimination. Evaluation used 600 independent objects (200 per class) from the testing partition through stratified random sampling, re-labelled by visual interpretation, with 95% confidence intervals from 1,000 bootstrap resamples. The seventeen-feature model outperformed the baseline, yielding Overall Accuracy of 93.00% (95% CI: 91.00–94.83) versus 89.00% (86.83–91.50), Macro-F1 of 92.92% versus 88.92%, and Cohen's Kappa of 0.895 (0.860–0.922) against 0.835 (0.795–0.873). Classification uncertainty concentrated at the Young-Harvestable boundary, whereas Overripe was consistently discriminated (F1 = 98.77%). Visible-band spectral statistics, GLCM and GLDV texture descriptors, and DSM-derived structural features contributed most to accuracy, while geometric descriptors showed marginal influence. The framework establishes a robust and economically accessible pathway for operational sago maturity monitoring.

Abstract

Sorghum flour has gained considerable attention as a gluten-free cereal with high nutritional value; however, its functional properties require improvement for industrial applications. This study aimed to investigate the effects of combined extrusion and enzymatic treatment on the morphological characteristics, thermal properties, and carbohydrate composition of pregelatinized sorghum flour. Three flour samples were prepared: native sorghum flour (PS1), extrusion-treated flour (PS2), and extrusion-enzymatic-treated flour with α-amylase (PS3). Morphological analysis was performed using polarized light microscopy and scanning electron microscopy. Thermal properties were assessed by differential scanning calorimetry (DSC), and carbohydrate composition was determined by high-performance liquid chromatography (HPLC). Results showed progressive loss of the Maltese cross pattern in PS2 and PS3, indicating disruption of crystalline structure, along with granule aggregation caused by amylose leaching. DSC analysis revealed that PS2 exhibited the most significant reduction in gelatinization temperature (To: 77.84 °C) and enthalpy (ΔH: 2.60 J/g) compared to native sorghum starch (To: 82.38 °C; ΔH: 7.52 J/g), representing a 57% decrease in ΔH. In contrast, PS3 showed no detectable endothermic peak (n.d.), indicating complete loss of residual crystalline structure. HPLC analysis confirmed extensive starch hydrolysis in PS3, with glucose concentration increasing more than 15-fold (77.31 mg/mL) compared to PS1, along with elevated maltose (12.05 mg/mL) and fructose (8.13 mg/mL) concentrations. These findings demonstrate that extrusion-enzymatic treatment effectively modifies sorghum flour structure, enhancing sugar release and altering thermal characteristics, thereby indicating improved functional properties for applications in instant foods, bakery products, and fermentation processes.

Abstract

The utilisation of moringa leaves as a functional food ingredient is constrained by nutrient losses during thermal processing and limited sensory acceptability due to undesirable flavour characteristics. Optimising blanching conditions while incorporating umami-rich nori is therefore essential to improve antioxidant retention, nutritional quality, and consumer acceptance of moringa-based seasonings. This study aimed to optimise blanching temperature and nori incorporation in the formulation of moringa flake (Bon Kelor), a functional food seasoning. A factorial experimental design was employed with three blanching temperatures (70°C, 80°C, and 90°C) and three levels of nori (5%, 10%, and 15%). Analyses included antioxidant activity (DPPH), proximate composition, sodium content, and hedonic sensory evaluation. The results showed significant effects of both blanching and nori concentration on antioxidant activity, macronutrient levels, and organoleptic properties (p < 0.05). The best formulation was obtained at 90°C with 15% nori, featuring high antioxidant activity (73.72%), protein (18.34%), and energy (370.39 kcal/100 g). The by-difference method revealed increased carbohydrate content with nori addition, attributed to water-soluble polysaccharides. Sensory analysis confirmed high panellist acceptance for colour, aroma, and taste. Blanching enhanced nutrient retention, reduced moisture, and improved flavour. In summary, combining thermal treatment with seaweed enrichment offers a valuable strategy to produce nutritious and acceptable moringa-based food products.
