Spinach (Amaranthus hybridus L.) is a perishable commodity, necessitating diversification into chips to increase its value-added. The organoleptic quality of spinach chips is strongly influenced by the frying medium. This study aimed to analyze the effect of using palm cooking oil and margarine as deep-frying media on the sensory characteristics of spinach chips. The research employed an experimental method with a single-factor Completely Randomized Design (CRD). Sensory quality testing was conducted using a hedonic test with 30 semi-trained panelists focusing on color, aroma, texture, and taste attributes. Data were analyzed using the non-parametric Wilcoxon Signed-Rank Test. The results showed that the type of frying medium had a significant effect (p < 0.05) on taste and texture attributes, where chips fried in cooking oil were preferred over margarine. However, no significant differences (p > 0.05) were found in color and aroma attributes. It is concluded that cooking oil remains the best medium for maintaining the palatability of spinach chips compared to margarine.

Intensive conventional agricultural systems that rely continuously on synthetic chemical fertilizers have triggered land degradation, decreased soil organic matter, and disrupted ecosystem balance. One of the important pillars of sustainable agriculture is the restoration of soil health through adaptive nutrient management based on local potential. This literature-based scientific article aims to examine the potential, effectiveness, and mechanisms of various types of agricultural waste, such as rice straw, fruit peels, livestock manure, and plantation waste, that are converted into organic fertilizers (solid, liquid, and bokashi). The results of the review indicate that the application of bioactivators (MOL or EM4) and appropriate composting techniques can accelerate the decomposition process, increase the content of macronutrients (N, P, and K) and micronutrients, and improve the physical, chemical, and biological properties of the soil. This implementation strategy contributes directly to reducing external agricultural input costs (Low External Input Sustainable Agriculture (LEISA)) while reducing environmental emissions from open waste burning.

Robusta coffee is a strategic plantation commodity for Indonesia, yet the quality of its ground coffee depends heavily on how each processing stage is carried out and controlled. Previous studies have largely examined the physical, chemical, and sensory effects of individual processing steps, while the processing chain has rarely been described as an integrated system. This study aims to analyze the processing of Robusta coffee beans into ground coffee using a systems modeling approach. A qualitative descriptive method was applied by developing a schematic system diagram, a process flowchart, a use case diagram, a business process diagram, and a Business Process Model and Notation (BPMN) model, with the use case and BPMN models validated in PowerDesigner. The results show that the processing system consists of interrelated components: stakeholders, inputs, processes, outputs, resources, controls, and threats. The process runs through sequential stages from sorting, pulping, soaking, draining, drying, and hulling to roasting and grinding, involving seven actors with clearly divided responsibilities. Both the use case and BPMN models passed validation with no errors or warnings. The resulting models provide a comprehensive representation of the processing workflow and can serve as a basis for evaluating, improving, and developing more efficient Robusta coffee processing systems.

The objectives of this study were to: (1) determine the interaction between cattle manure compost dosage and Bio7 bioactivator biofertilizer concentration regarding rice plant growth and yield; and (2) identify the optimal combination of cattle manure compost dosage and Bio7 bioactivator biofertilizer concentration for rice plant growth and yield. The study employed a factorial Randomized Block Design (RBD) consisting of two factors and three replications. The first factor was the cattle manure compost dosage (K), comprising four levels: no cattle manure compost (K0), 159 g/polybag (equivalent to 10 t/ha; K1), 318 g/polybag (equivalent to 20 t/ha; K2), and 477 g/polybag (equivalent to 30 t/ha; K3). The second factor was the Bio7 biofertilizer concentration (B), comprising four levels: no biofertilizer (B0), 5 ml/L (B1), 15 ml/L (B2), and 25 ml/L (B3). Consequently, there were 16 treatment combinations; each treatment was replicated three times, and each treatment unit consisted of five plants. The results of the study showed an interaction between cattle manure compost dosage and Bio7 bioactivator biofertilizer regarding rice plant growth and yield. The treatment combination of 477 g/polybag of cattle manure compost and 25 ml/L of Bio7 bioactivator biofertilizer effectively enhanced rice plant growth and yield. The application of cow manure compost at a rate of 477 g/polybag, supplemented with the Bio7 bioactivator biofertilizer at a concentration of 25 ml/L of water, resulted in the highest GKG (28.66 g/hill).

The minapadi system is an integrated farming approach that combines rice cultivation with fish farming within the same paddy field simultaneously. This system is capable of improving land-use efficiency, agricultural productivity, farmers' income, and environmental sustainability through reduced pesticide use and optimized resource utilization. This study aimed to analyze and model the minapadi cultivation system using a systems and modeling approach to obtain a comprehensive understanding of the relationships among the components within the cultivation system. The study employed a qualitative descriptive approach through system modeling using schematic diagrams, flowcharts, Use Case Diagrams, Business Process Diagrams (BPD), and Business Process Model and Notation (BPMN). The analysis focused on the main system components, including stakeholders, inputs, processes, outputs, resources, control mechanisms, and threats. The results indicated that the success of the minapadi system is highly influenced by the interrelationships and integration among these components, starting from land preparation, rice planting, fish stocking, maintenance, and harvesting activities. Modeling using Use Case Diagrams and BPMN successfully illustrated stakeholder interactions, information flows, and business processes in a systematic and structured manner. In addition to simultaneously increasing rice and fish productivity, the minapadi system also provides economic and ecological benefits, making it a promising model for sustainable agriculture development in Indonesia. Furthermore, the developed model can serve as a foundation for developing information systems and decision support systems to enhance the effectiveness and efficiency of minapadi padi management.
