Abstract

Karo Regency, North Sumatra, is widely recognized as a major agricultural production center in Indonesia, particularly for vegetables, fruits, and ornamental crops, where the primary livelihoods of the population depend on food crops, horticulture, and mixed plantations. The region is also home to Mount Sinabung, an active volcano that re-erupted on August 27, 2010, after a long period of dormancy. More than ten years after the eruption, volcanic deposits have undergone gradual weathering processes that contribute to soil development. Through physical, chemical, and biological weathering, volcanic materials release essential nutrients that can enhance soil fertility and support agricultural production. However, comprehensive studies evaluating agricultural land suitability more than ten years (>10 years) after the eruption, based on current soil physical and chemical conditions, remain limited, particularly in identifying both actual and potential limiting factors affecting land utilization. This study aims to assess agricultural land suitability more than ten years after the eruption of Mount Sinabung in Karo Regency, North Sumatra. The evaluation was conducted to identify land potential and limiting factors that continue to influence post-eruption agricultural land use. The research employed a survey method using the FAO land suitability evaluation framework. The analyzed data included climatic conditions, soil physical and chemical properties, and land characteristics relevant to crop growth. Soil samples were collected at depths of 0–30 cm and 30–60 cm from eight villages representing variations in distance from the volcano and levels of volcanic material exposure. The urgency of this research lies in evaluating the current suitability level and carrying capacity of agricultural land more than a decade after the eruption to ensure appropriate commodity selection and management strategies based on present bio-physical conditions. The results indicate that agricultural land in the study area has undergone considerable recovery, although it still exhibits characteristics of young volcanic soils with dynamic properties. Land suitability evaluation shows that potato and Arabica coffee demonstrate relatively better adaptation, with actual and potential suitability classes ranging from S1 to S2 after improvements in dynamic limiting factors such as nutrient retention, rooting media, and water availability. In contrast, avocado development remains relatively limited due to temperature constraints, which are inherent and difficult to modify. These findings emphasize that land suitability evaluation is essential as a scientific basis for determining appropriate commodities and sustainable land management strategies in post-volcanic eruption areas.

Abstract

Thus far, efforts to boost agricultural productivity have relied heavily on chemical fertilizers. Unfortunately, this dependence has led to adverse environmental impacts, including soil structure degradation and groundwater contamination. To address this issue, transitioning to liquid organic fertilizer (LOF) could be an effective alternative. Oil palm fronds can be used as a raw material for LOF production, as their microbial decomposition has been shown to naturally improve soil physical characteristics. This research was conducted from February to May 2025 at Educational Garden 1 of the Citra Widya Edukasi Oil Palm Polytechnic, located on Cisaat Setu Street, Ciledug Village, Setu District, Bekasi Regency, West Java, 17320. The study employed a single-factor Completely Randomized Design (CRD). The application of liquid organic fertilizer was applied at 5 doses, with each treatment involving 2 sample plants and replicated 3 times. The five treatments evaluated in this study were: P0 (without LOF), P1 (20 ml of LOF with EM4 decomposer), P2 (50 ml of LOF with EM4 decomposer), P3 (20 ml of LOF with banana corm local microorganism [MOL] decomposer), and P4 (50 ml of LOF with banana corm local microorganism [MOL] decomposer). The results demonstrated that the application of LOF significantly affected plant height, stem diameter, and leaf count. The highest seedling height at 6 weeks after planting (WAP) was observed in the P2 treatment (50 ml of LOF with EM4), which was significantly higher than P3 but not significantly different from P0, P1, or P4.

Abstract

Porang (Amorphophallus muelleri) is a tuber crop with promising economic potential and the capacity to serve as a source of income for rural communities. This study was conducted to assess the welfare of porang farmers, identify the development prospects of porang cultivation, and examine the influence of these prospects on farmers’ welfare in Weewela Village, North Kodi District, Southwest Sumba Regency. A descriptive quantitative approach with a survey method was employed in this research. A total of 30 porang farmers were selected as respondents through purposive sampling based on the criteria of actively cultivating porang and having at least one planting season of farming experience. Data were collected through field observations, interviews, and questionnaires using a Likert scale. The data were subsequently analyzed using descriptive statistics and simple linear regression in SPSS version 25. The findings revealed that the welfare condition of porang farmers in the study area was relatively favorable. As many as 76.7% of respondents were categorized as having a high level of welfare, while 23.3% were classified in having a moderate level. Regarding business development opportunities, 90.0% of respondents perceived the prospects of porang cultivation as good to very good, supported by land availability, market opportunities, and the potential to increase income. The regression analysis demonstrated that the development prospects of porang cultivation had a positive and significant effect on farmers’ welfare, as indicated by the equation Y = 12.453 + 0.587X and a significance value of 0.000 (p < 0.05). The coefficient of determination (R²) was 0.469, indicating that 46.9% of the variation in farmers’ welfare could be explained by the development prospects of porang cultivation, while the remaining proportion was influenced by other factors not included in the model. Therefore, efforts to develop porang cultivation should be strengthened by enhancing farmer institutions, improving cultivation and post-harvest management skills, and expanding market access to sustainably improve farmers’ welfare.

Abstract

East Java Province is one of the major agricultural production centers in Indonesia with diverse biophysical characteristics. Variations in topography, climate, soil properties, and vegetation conditions contribute to differences in agricultural land suitability across the region. This study aimed to analyze agricultural land suitability in East Java Province using a Random Forest algorithm integrated with Geographic Information Systems (GIS) and multisource geospatial data. The variables employed included elevation, slope, aspect, rainfall, temperature, soil pH, soil organic carbon (SOC), Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), and Normalized Difference Water Index (NDWI). Data were obtained from SRTM, CHIRPS, TerraClimate, SoilGrids, Landsat 8, and ESA WorldCover datasets. The Random Forest model was developed using 80% of the samples for training and 20% for testing. Model evaluation showed an overall accuracy of 80.12%, a Cohen’s Kappa coefficient of 0.4212, and an ROC-AUC value of 0.8596, indicating good classification performance. Feature importance analysis revealed that slope was the most influential variable (18.43%), followed by NDWI (14.69%), elevation (12.24%), and NDVI (11.63%). Spatial analysis indicated that moderately suitable land dominated East Java, covering approximately 3.28 million ha (48.71%), followed by land of low suitability, covering 2.00 million ha (29.75%), and highly suitable land, covering 1.45 million ha (21.54%). The results demonstrate that integrating Random Forest with GIS provides an effective approach for assessing agricultural land suitability and can support sustainable agricultural planning and spatial decision-making in East Java Province

Abstract

Food crops must always be prioritized for the community's basic needs to ensure food supplies. Staple crops such as rice, corn, and soybeans have long been a top priority for national food security, with their productivity and quality consistently receiving government attention. Job's tears, as an alternative food crop, have begun to be tested for their high nutritional value, approaching that of the main staple crop. However, one obstacle to Job's tears cultivation is the thick seed coat, which inhibits germination. Soaking at different temperatures can crack the tough seed coat. This study aims to determine the physiological responses (flowering time and chlorophyll content), yield components, and yield of Job's tears using soaking at varying temperatures. This research was conducted at Rancaekek Village Garden, Bandung Regency, from June 2025 to February 2026 using a Randomized Block Design (RBD), namely soaking using different temperatures. The treatments in this study were s0 (without soaking), s1 (plain water), s2 (temperature 30°C), s3 (temperature 40°C), and s4 (temperature 50°C), with each treatment repeated 5 times. Observations in this study consisted of observations of yield components, consisting of the number of panicles per tiller, the number of seeds per clump, the weight of 100 grains, and observations of yields, consisting of the seed weight per clump, the seed weight per plot, and the harvest index. The results showed that soaking seeds in warm water had an effect on the number of panicles, the number of seeds, and seed weight. Soaking seeds in warm water at 40 oC showed the best effect on yield components and yield observations. The highest yield was achieved with the soaking treatment at 40°C, at 287.11 g per plant, or approximately 5.4 tons/ha

Abstract

Tomato (Solanum lycopersicum L.) is an important horticultural crop that requires high-quality seeds to achieve optimal growth and development. One approach to improving the physiological quality of seeds is organic priming using environmentally friendly natural materials. Moringa (Moringa oleifera L.) leaves contain various bioactive compounds, including cytokinins, auxins, vitamins, minerals, and antioxidants, which have the potential to enhance seed germination and vigor. This study aimed to evaluate the effect of organic priming with moringa leaf extract on tomato seed germination and vigor and to determine the most effective extract concentration. The experiment was conducted at the Laboratory of Weetabula Catholic University from April to May 2026 using a Completely Randomized Design (CRD) with a single factor consisting of moringa leaf extract concentrations: P0 (0%), P1 (25%), P2 (50%), P3 (75%), and P4 (100%), with four replications. Tomato seeds were soaked in the extract solutions according to the treatments for 12 hours and subsequently germinated using the rolled paper test method. The observed variables included germination percentage, germination rate, vigor index, primary root length, plumule length, and seedling fresh weight. Data were analyzed using analysis of variance (ANOVA) at the 5% significance level, followed by the Least Significant Difference (LSD) test at the 5% level. The results showed that organic priming with moringa leaf extract significantly affected all observed parameters. The P3 treatment (75% extract concentration) produced the best results, with a germination percentage of 96.25%, germination rate of 22.08% day⁻¹, vigor index of 89.50, primary root length of 5.95 cm, plumule length of 7.43 cm, and seedling fresh weight of 0.69 g. The P3 treatment did not differ significantly from P2 (50%) but differed significantly from P4 (100%), P1 (25%), and P0 (control). Therefore, moringa leaf extract at a concentration of 75% was the most effective treatment for improving tomato seed germination and vigor and has potential as an inexpensive, environmentally friendly, and sustainable seed enhancement technology

Abstract

Sauropus androgynus L. is an indigenous leafy vegetable with high nutritional value that is commonly propagated vegetatively through stem cuttings. The success of cutting propagation is influenced by the quality of planting material and the application of plant growth regulators (PGRs). This study aimed to evaluate the effects of cutting length and natural plant growth regulators on the vegetative growth of S. androgynus and to determine the best treatment combination for promoting plant growth. The experiment was conducted at the Greenhouse of the Faculty of Agriculture and Animal Science, Universitas Ma'arif Nahdlatul Ulama Kebumen, Indonesia, from May to June 2026 using a two-factor Completely Randomized Design (CRD) with three replications. The first factor was the type of plant growth regulator, consisting of a control (water), 100% coconut water, and 100% rice washing water, while the second factor was cutting length, consisting of 45 cm, 60 cm, and 75 cm. The observed parameters included shoot length, number of leaves, stem diameter, root length, root fresh weight, and root dry weight. Data were analyzed using analysis of variance (ANOVA), followed by Duncan's Multiple Range Test (DMRT) at the 5% significance level when significant differences were detected. The results showed that cutting length significantly affected the number of leaves and root fresh weight, whereas the type of plant growth regulator had no significant effect on any of the observed parameters. The interaction between plant growth regulator type and cutting length significantly affected the number of leaves. The treatment using 60 cm long cuttings combined with plain water and rice-washing water yielded the highest number of Sauropus androgynus leaves compared to the other treatment combinations
