Abstract

Organic waste is an abundant resource but remains underutilized as a safe and nutrient-rich organic fertilizer. This study aims to evaluate the effectiveness of Trichoderma as an alternative bioactivator to EM4 in improving the quality of liquid organic fertilizer (LOF) and compost through tiered bucket systems under aerobic (A2) and anaerobic (A1) conditions. A randomized complete block design was used with five Trichoderma doses (0; 15; 20; 25; 30 mL.L⁻¹) and EM4 (30 mL.L⁻¹) as a comparison. The liquid and solid fractions were analyzed for C, N, C/N ratio, P₂O₅, K₂O, and heavy metals (Pb, Cd, Cu) using standard methods. The data were analyzed through ANOVA and orthogonal contrast tests. Results showed that the aerobic system consistently reduced the C/N ratio, producing more mature and stable products, while the anaerobic system tended to retain higher C-organic content. These differences were statistically significant as the aerobic condition (A2) decreased the C/N ratio by 4.74 or 40.93% in liquid organic fertilizer and by 3.62 or 19.52% in compost compared to the anaerobic condition (A1), while total P₂O₅ in liquid organic fertilizer increased by about 14.81% under A2. Medium–high doses of Trichoderma (25–30 mL L⁻¹) in the aerobic system yielded the best quality in terms of maturity, whereas EM4 generally resulted in higher macro-nutrient contents (N, P₂O₅, K₂O). All heavy metal levels were far below the SNI/Ministry of Agriculture thresholds, indicating product safety. Practically, the A2–T3/T4 combination is recommended to produce mature, stable, and safe organic fertilizer, while co-inoculation strategies may be pursued to enhance nutrient content. This study confirms that Trichoderma primarily accelerates humification and stabilizes organic matter, offering a practical, low-cost option for household/community organic waste management within a circular-economy framework; accordingly, the aerobic bucket system with medium–high Trichoderma doses (A2–T3/T4) is recommended to achieve mature, stable LOF–compost. However, the findings are lab-scale and substrate-specific.

Abstract

SMV infection at early growth stages can reduce crop productivity by 25.48% to 93.84%. Viral infections may reduce plant growth due to disruptions in physiological processes and photosynthetic output, hormonal imbalances, and decreased nutrient uptake, ultimately preventing the plant from growing optimally. The research was conducted at the Experimental Field and Basic Science Laboratory of the Faculty of Agricultural Technology, Satu Nusa Lampung University, as well as the Analysis Laboratory of Politeknik Negeri Lampung, from May to August 2025. The method used in this research was an experimental method. The study employed a Randomized Complete Block Design (RCBD) with the following treatments: T0 = Control, T1 = 10 ml Trichoderma solution, T2 = 20 ml Trichoderma solution, T3 = 30 ml Trichoderma solution, T4 = 40 ml Trichoderma solution,T5 = 50 ml Trichoderma solution per plant (with a spore concentration of 1 ml T. asperellum = 46.5 × 10² spores). Result Based on the study of the potential of Trichoderma asperellum in enhancing the resistance of soybean plants infected with SMV, it can be concluded that the 50 ml T. asperellum treatment showed the best results, with an incubation period of 18 days after inoculation (DAI), disease severity of 14%, and a plant resistance rating categorized as resistant to SMV. The highest yield increase was also recorded in the 50 ml Trichoderma treatment (T5), reaching 77.45%.

Abstract

Sweet corn is an important food commodity after rice. The production of sweet corn in Indonesia is 8.31 tons per hectare, while its potential is 18–25 tons per hectare. Low sweet corn production is caused by excessive use of inorganic fertilizers and downy mildew disease attacks, which can reduce harvest yields by 50–100%. This study aims to determine the effectiveness of applying liquid organic fertilizer (LOF) made from organic waste with the bioactivator Trichoderma using a Tiered Bucket System to improve the growth and production of sweet corn, as well as its resistance to downy mildew disease. The study was conducted at the Experimental Garden of the Faculty of Agricultural Technology, Universitas Satu Nusa Lampung. The experiment used a two-factor completely randomized block design (CRBD). The first factor was LOF produced through anaerobic (A1) and aerobic (A2) fermentation using the Tiered Bucket System. The second factor was LOF fermentation treatments without bioactivator (T0); with Trichoderma bioactivator at 15 mL/L (T1), 20 mL/L (T2), 25 mL/L (T3), 30 mL/L (T4); and EM4 bioactivator at 30 mL/L (Em) as a comparison. Trichoderma at 30 mL/L (T4) consistently gave the best results in improving growth, production yield, chlorophyll content, and resistance to downy mildew disease in sweet corn plants. Treatment T4 produced the highest chlorophyll content and the lowest disease intensity, indicating healthier plants with better tolerance to biotic stress. Aerobic fermentation was more effective than anaerobic in improving LOF quality and bioactivator effectiveness. Although EM4 also showed benefits, it was less effective than Trichoderma, especially in suppressing downy mildew disease. The use of LOF with Trichoderma bioactivator and aerobic fermentation is highly recommended to sustainably improve sweet corn productivity and disease resistance.

Abstract

Ultisols are characterized by strong acidity, low cation exchange capacity, and high phosphate fixation, which limit nutrient availability and crop productivity. Sustainable fertilization strategies are needed to improve soil quality and reduce dependence on inorganic inputs. A pot experiment was conducted from January to August 2025 using a randomized complete block design with nine treatments and three replications (270 plants). Treatments included combinations of 50% NPK fertilizer with liquid organic fertilizers (LOFs) derived from goat urine, rabbit urine, banana peels, and pineapple peels. Data were analyzed using analysis of variance (ANOVA), followed by orthogonal comparison tests. The combined application of LOFs with 50% NPK significantly increased biomass, bulb yield, soil CEC, organic C, total N, available K, and plant N and K uptake (p < 0.01) compared to 100% NPK. Yield increased by 27.7%, while N and K uptake rose by 63.0% and 65.0%, respectively. Rabbit urine LOF showed the highest effectiveness, improving yield by up to 36.0% compared to goat urine. Plant-based LOFs enhanced soil organic C, CEC, and K availability, whereas animal-based LOFs were more effective in increasing soil N. The integration of LOFs with reduced NPK improves soil fertility and shallot productivity under controlled conditions. Rabbit urine LOF at 300 mL L⁻¹ is the most effective treatment. However, field validation is required before large-scale application.
