Abstract

This study designs and implements an input recommendation system for smallholder coffee agribusiness to close productivity and efficiency gaps. The objective is to assess how decision analysis guides farmers toward input combinations aligned with goals, budget constraints, and field risks. The methodology applies decision analysis: candidate input allocations are formulated; evaluation criteria (yield, total cost, risk exposure, ease of implementation) are specified; criterion weights are elicited through structured judgments; scores are normalized and aggregated; and sensitivity analysis tests robustness to weight and price changes. Results show that the recommendation-based alternative consistently outperforms conventional practice on most criteria, raising productivity while lowering cost per unit of output and reducing risk under volatile weather. Stability of rankings across sensitivity tests indicates durable performance across diverse farmer preferences. The findings highlight the need for targeted technical assistance and financing aligned with recommended inputs to support sustained adoption and scalable replication across regions.

Abstract

This study aims to examine the impact of the application of Artificial Intelligence (AI) in financial risk management in FinTech companies. With the increasing reliance on technology, AI has great potential in managing various types of risks, such as credit, market and liquidity risks. This study uses a quai-experimental approach by comparing two groups of companies, namely companies that use that do not use AI. The data collected included the level of non-performing (NPLs), market value fluctuations, and liquidity stability, which were analyzed using t-test and ANOVA to identify significant differences between the two groups. The results showed that companies that implemented AI experienced a significant decrease in bad debt rates, more manageable market values fluctuations, and improved liquidity stability. However, the main challenges faced in implementing AI include limited quality data technological comnpetency, and regulatory compliance. Overall, this study reveals that the application of AI can improve the effetiveness of financial risk management in FinTech firms, but requires investment in employee training, technological infrastructure development, and attentionto regulatory aspects to maximize the benefits.

Abstract

Chemical fertilizers are increasingly rare and expensive, causing farmers (partners) to look for solutiosn by using organic fertilizer as a combination. However, a problem is currently being faced by partners, namely related to the production process of organic fertilizer made from goat manure. The characteristics of goat manure are hard, and it takes quite a long time to decompose, so farmers have to wait approximately one month before it can be applied as basic fertilizer on agricultural land. Efforts to speed up the decomposition process have been made by partners, namely by crushing or smoothing goat manure by pounding it manually. This stage requires quite a lot of time and energy, so it is felt to be less efficient. This is due to the lack of technology adopted in the partner environment. Based on the conditions and problems faced by partners, through this activity a solution will be offered in the form of technology for processing goat manure as raw material for organic fertilizer. This technology is in the form of a goat manure crushing machine to help speed up the decomposition process and provide nutrients, so that partners do not have to wait long for planting to start. This community service activity is carried out by providing counseling and training in making organic fertilizer from goat dung as raw material, accompanied by the use of a goat dung crushing machine. It is hoped that partners’ knowledge and skills can increase, especially in processing organic fertilizer made from goat manure.

Abstract

Sweet corn (Zea mays L. Var saccharata Sturt) has a high demand in Indonesia, but its productivity is threatened by drought; therefore, it is necessary to analyze its growth under drought stress conditions. This study aims to observe the morphological and physiological responses of sweet corn plants to drought stress and potassium administration. The research was conducted over a three-month period at the experimental garden of the Faculty of Agriculture, University of Riau. A Factorial Completely Randomized Design (RA LF) was used with two factors: drought stress and potassium fertilization. The study consisted of three levels of potassium fertilization, with three replications, resulting in a total of 18 experimental units. The first factor: A1 = everyday; A2 = drought stress. The second factor: K 1 = 2.3 g K 2 O plant -1; K 2 = 2.8 g K 2 O plant -1; K 3 = 180 kg K 2 O ha -1. Analysis of Variance was continued with the Honestly Significant Difference (HSD) test at 5% level. The observed parameters consisted of physiological and morphological factors in sweet corn plants. The study found that drought stress negatively impacted the physiological parameters of sweet corn, including reduced plant water content and increased proline levels. Additionally, drought stress decreased key morphological traits, including plant height, root condition, cob husk weight, cob husk length, and cob husk diameter. However, the application of potassium fertilizer, particularly at a dose of 3.4 g K₂O plant-1, significantly improved the length of the cob husk. Overall, increasing potassium application under drought stress conditions tended to enhance both morphological and physiological parameters of sweet corn.

Abstract

Smallholder dairy farming plays a crucial role in rural livelihoods and food security in developing countries, yet it is highly exposed to multidimensional risks that threaten its sustainability. While previous studies have examined agricultural risks and sustainability separately, limited attention has been given to how these risks interact to shape system resilience and adaptive capacity. This study aims to analyze resilience in smallholder dairy farming by integrating Enterprise Risk Management (ERM) with a multidimensional sustainability framework. A case study was conducted in Suci Village, Jember Regency, Indonesia, involving 30 respondents, including farmers, cooperative representatives, and agricultural officers. Data were collected through focus group discussions, semi-structured interviews, and field observations. Risks were identified and assessed using an ERM-based risk register matrix, evaluated through likelihood and impact scoring. The results were subsequently reinterpreted using a resilience framework, linking risk exposure, sensitivity, and adaptive capacity. The findings reveal that most risks are concentrated in the high and extreme categories, indicating a structurally vulnerable system with low baseline resilience. Risks are highly interconnected across ecological, economic, social, and technological dimensions, generating cascading effects that amplify system instability. Technological limitations and weak institutional capacity were identified as key constraints to adaptive capacity, further increasing vulnerability to recurring shocks. This study contributes to the literature by extending ERM from a risk classification tool into a resilience-oriented analytical framework. By integrating risk management with sustainability dimensions, the study provides a novel approach to understanding and strengthening resilience in smallholder agribusiness systems. The findings offer practical implications for developing integrated, context-specific strategies to enhance long-term sustainability and adaptive capacity in smallholder dairy farming.
