The use of liquid organic fertilizer (POC) is an innovative solution to increase crop productivity in drylands that face challenges in soil fertility and water availability. This study aims to evaluate the effect of various types of POC, including moringa, kirinyu, rabbit urine, fermented fruit waste, and local microorganism-based (MOL) POC, on plant growth and yield. The method used was literature review and analysis of literature from various journals, theses, theses, and dissertations, which were analyzed descriptively and quantitatively.  The results showed that all types of POC increased plant productivity with an average increase of 20-40% compared to the control, with rabbit urine recording the highest increase of 40%. The effectiveness of POC comes from the content of nutrients, bioactive compounds, and microorganisms that improve soil structure, increase water retention, and spur nutrient absorption. The discussion underscored the importance of utilizing local resources to reduce environmental pollution and improve agricultural sustainability.  In conclusion, POC proved to be an effective alternative to increase crop yields in drylands while supporting sustainable agriculture. Recommendations for further research include further exploration of local organic materials and application of POC on a field scale.

Fertilizer is an important factor in increasing the growth and yield of chili plants (Capsicum annuum L.). The selection of the right type of fertilizer greatly determines productivity and environmental sustainability in the long term. This study aims to analyze the differences between chemical fertilizers and organic fertilizers in chili plant cultivation, including plant growth, yields, and their impact on soil fertility. The method used is a literature review by examining various previous studies that discuss the effectiveness of both types of fertilizers. The results of the analysis show that chemical fertilizers provide faster growth and higher yields in the short term because their nutrients are more easily absorbed by plants. However, excessive use can cause soil degradation, decreased organic matter content, and environmental pollution. In contrast, organic fertilizers work more slowly, but are able to increase soil fertility, improve soil structure, and support the balance of agricultural ecosystems in the long term. The combination of chemical and organic fertilizers has proven to be the best strategy in increasing chili productivity while maintaining soil health. Therefore, balanced fertilization with the right dose is highly recommended to ensure optimal harvest results without damaging the environment.
