No full textThe palm breeding and cultivation challenges are mainly related to the seed germination process. Various factors, including seed dormancy, often influence this process. Various scarification methods and several types of palms that can play a role in breaking dormancy need to be tried. This research aims to determine the best dormancy-breaking scarification method for various palm seeds. This research was carried out in Bakung Village, Sukasada District, Buleleng Regency, from January to March 2024, using a Nested Design comprising two factors. The first factor is that the type of palm seed consists of four levels: Putri palm, Pinang palm, Squirrel Tail palm, and Green palm. The second factor consists of six levels, namely control method (without peeling), peel scarification method, peel scarification method+warm water, peel scarification method+H2SO4, peel scarification method+KNO3, peel scarification method+GA3. The results of the research showed that the scarification method had a significant effect (p<0,05) on the percentage of sprouts and shoot length. Very significant effect (p<0,01) on the variables of germination, maximum growth potential, seed growth speed, and root length, had an not significant effect on the synchronization of seed growth. This research concludes that the scarification method affects breaking seed dormancy in several types of palm, except for the areca palm

The results of microscopic characterization and molecular tests show that the fungal isolate used in this study has 99% similarity with Fusarium oxysporum f. sp. lycopersici. Essential oils extracted from citronella plants effectively inhibit the formation of fungal colonies. This is evidenced by the results of observation at the age of 7 HSI mushrooms with the growth diameter of fungal colonies of 5.06 cm, 3.56 cm, and 2.44 cm after applying essential oils with concentrations of 333 ppm, 666 ppm, and 1000 ppm. Results of observation and calculation of cellulase enzyme activity values in Fusarium oxysporum f. sp. lycopersici isolate. Cellulase enzyme activity of 0.831 U/mL was obtained. The application of essential oils with sequential concentrations (333 ppm, 666 ppm, and 1000 ppm) was able to decrease the activity of cellulase enzymes, with activity inhibition of 31%, 39%, and 44% in Fusarium oxysporum f. sp. lycopersici isolates
Effectiveness of Local Indigenous Rhizobacterial Isolates in Enhancing Resistance of Shallot (Allium cepa L.) to Fusarium oxysporum
Full text linkFusarium wilt caused by Fusarium oxysporum remains a major limitation in shallot (Allium cepa L.) cultivation, severely reducing yield and crop quality. This study aimed to evaluate the effectiveness of native rhizobacterial isolates as biological inducers of resistance against Fusarium wilt under different organic growing media. A split-plot randomized complete block design was applied using three growing media (rice husk charcoal, manure, and their combination) and four rhizobacterial treatments (control and three local isolates: R1–R3) with three replications. Key physiological assays included the measurement of salicylic acid (SA) content and peroxidase (POX) enzyme activity as biochemical indicators of induced resistance. Results showed that the isolate from Waitii Village (R3) significantly reduced disease incidence to 52.67% compared with 86.56% in the control, while the combined organic medium (M2) further enhanced plant resistance. Increased SA (26.82 ppm) and POX activity exhibited strong negative correlations with disease incidence (R² = 0.60 and R² = 0.71, respectively), indicating their pivotal role in rhizobacteria-mediated defense activation. These findings confirm that indigenous rhizobacteria, when combined with organic amendments, effectively stimulate systemic acquired resistance and mitigate the severity of Fusarium wilt in shallots. The study highlights the potential of the R3 isolate as a sustainable bioinoculant candidate for integrated disease management. Further molecular identification, in vitro antagonism testing, and multi-location field validation are recommended to ensure its stability, efficacy, and applicability under diverse agroecological conditions
Discriminating Estate and Smallholder Agricultural Systems Using a Multi-Sensor Agriculture-Weighted Object-Based Classification Framework in Tropical Landscapes
Full text linkThe transformation of tropical landscapes due to agricultural expansion constitutes a significant global environmental challenge. Current land-cover classification methods, however, provide limited differentiation among agricultural management systems. This study develops an agriculture-focused land-cover classification workflow that fuses Landsat 9 optical imagery and PALSAR-2 L-band SAR across a ≈2,500 km² study area in Jambi Province, Sumatra, Indonesia, to enhance discrimination of crop systems and improve spatial coherence via object-based enhancement. A 22-class land-cover taxonomy was supported by 14,029 strategically collected training points. Feature engineering produced 29 predictor variables, including conventional vegetation indices, agricultural-specific metrics, water indicators, and SAR-derived structural features. Models were evaluated on an independent test dataset comprising 4,209 samples. An agriculture-weighted Random Forest classifier with strategic class weighting was implemented and followed by Simple Linear Iterative Clustering (SLIC) object-based enhancement to suppress speckle and enforce spatial contiguity. The classification achieved an overall accuracy of 53.7%, with exceptional performance for estate crop systems (F1 = 94%) and reliable forest discrimination. SLIC reduced salt-and-pepper noise by 99.5% and substantially improved spatial coherence metrics, transforming fragmented pixel-based outputs into operationally viable products. Despite these gains, discriminating smallholder mosaics remains challenging and likely requires additional temporal or higher-resolution inputs
The Role of the Millennial Generation in Developing Urban Farming as a Food Security Solution for Times of Crisis in Indonesia
Full text linkThis research analyses the role of millennials in the development of urban farming in Malang Regency, representing an area with high urban farming potential in Indonesia. Using a quantitative approach through an explanatory survey design, the study involved 210 millennial farmer respondents (aged 25-40) from 33 sub-districts in Malang Regency. Data was collected through a structured questionnaire with a 5-point Likert scale and analysed using PLS-SEM with WarpPLS 8.0. The model tests the relationship between five exogenous variables: Digital Technology Competency (X1), Entrepreneurial Ability (X2), Technical Knowledge (X3), Sustainability Awareness (X4), and Ecosystem Support (X5), and Local Food Resilience (Y), with Innovation Adoption (M) as a mediator. The main findings show the model is excellent (R² = 0.937) with all hypotheses significantly confirmed. Entrepreneurial ability has the strongest influence (β=0.42, p<0.05), followed by Digital Technology Competence and Ecosystem Support (β=0.36), Sustainability Awareness (β=0.31), and Technical Knowledge (β=0.25). Innovation adoption is proven to be an effective mediator, especially through Ecosystem Support (β=0.65, p<0.01). The research identified two innovative models: the NFT Vertical Hydroponic System and the IoT-based Smart Greenhouse Integrated Farming, which achieved 90% water efficiency and produced premium products. The significance of the research lies in its theoretical contribution regarding the role of millennials in food security and its practical implications for the development of national agricultural policy. The findings can be replicated in other urban areas of Indonesia with similar demographic and geographic characteristics, providing a blueprint for sustainable urban farming development to strengthen national food security
Integrating Supply Chain Management into Food Estate Models for Enhanced Food Security
Full text linkThis study analyzes the integration of supply chain management (SCM) within a food estate model on lowland swamp agroecosystems to strengthen national food security. A descriptive–analytical survey was conducted for eight months involving 60 farmers from three farmer groups in Muara Belida, South Sumatra. Performance was assessed using the SCOR v13.0 framework, value-added analysis (Hayami method), KPI weighting (ANP), and performance measurement (OMAX with Traffic Light System). Results show an overall SCM performance index of 7.892 (yellow category), with “Deliver” (8.280), “Make” (8.258), and “Return” (8.025) performing relatively well, while “Plan” (7.520) and “Source” (7.758) remain moderate. Policy and managerial implications highlight the need for farmer training, adoption of climate-resilient crop varieties, demand forecasting systems, and formal contractual partnerships to stabilize supply and reduce transaction costs. Findings further reveal that SCM integration enhances value addition at the farmer level and mitigates systemic risks, thereby contributing to food security by reducing logistics costs and building supply chain resilience. This research provides empirical evidence that incorporating SCM into food estate development constitutes a critical strategy for sustainable agro-industrial cluster management in lowland swamps and for achieving national food security
