Potential of Organic Liquid Fertilizer from Rice Washing Water and Goat Urine on The Growth of Pak Choi (Brassica rapa L. var. Chinensis) Using Hydroponic Method
Get PDFHydroponics, an emerging agricultural technology, allows cultivation without soil, but using nutrient-rich water instead. This is promising for future agriculture, as it can be applied in various locations and offers higher quality production results, thus increasing market competitiveness. In addition, waste materials such as rice washing water and goat urine can be reused as valuable organic fertilizers. Rice washing water, rich in nutrients such as vitamin B1, phosphorus, calcium, and nitrogen, serves as a liquid organic fertilizer that promotes superior plant growth. Goat urine, containing natural phytohormones, supports root and shoot development, making it a useful alternative to organic fertilizers. Research shows that liquid organic fertilizers are often preferred over synthetic options in hydroponic systems due to their higher bioactive compound content and environmental safety. This study focuses on the cultivation of Pak Choi (Brassica rapa var. Chinensis) using various nutrient treatments, including rice washing water, goat urine, and AB Mix, with measured concentrations ranging from 1000 to 1400 Part Per Millions (PPM). The results showed significant differences in growth among the treatment groups, with AB Mix producing the highest plant height, number of leaves, and leaf width, indicating the effectiveness of nutrient type on plant development

The Preparation and Formulation of Moringa oleifera Lam. Leaf Extract in Transdermal Patch
Get PDFThe anti-fibrotic, anti-inflammatory, and antimicrobial qualities of moringa leaf extracts, which are high in saponins, flavonoids, steroids, and phenols, can aid in tissue regeneration and wound healing. The aim of this study was to prepare and formulate a transdermal patch of Moringa oleifera Lam. leaf extract with hydroxypropyl methylcellulose (HPMC) and polyvinyl pyrrolidone (PVP) as the polymers. The study was aimed at investigating the effect of various concentrations of the extract (20%, 40%, and 80%) on the physical properties of the patch, including organoleptic properties, weight uniformity, thickness, folding endurance, pH, and water absorption. Extract was made by maceration with 96% ethanol, and patches were cast by the solvent casting method. Results showed that all formulations met the required pH range (6.62–6.68), folding endurance (>300 folds), and thickness (<1 mm). However, weight uniformity and moisture absorption exceeded desired optimum values and ranged between 17% to 23%. The 20% concentration of extract exhibited the maximum physical stability. This study highlights the potential of Moringa oleifera leaf extract in transdermal patch preparations, although it needs to be optimized to improve weight consistency and water absorption

Association of Coral Life Form with Megabenthos, Pasumpahan Island, Padang City
Get PDFPasumpahan Island is a popular tourist destination in the Padang area. Increasing tourist activity is suspected to contribute to the degradation of the coral reef ecosystem, as observed during preliminary surveys. Coral reef degradation can significantly impact associated marine organisms, particularly megabenthos species. This study examined the association between coral life forms and megabenthos types through direct field observations. A quadrat method was applied using 5×5 m² plots across nine locations. Data analysis employed 2x2 contingency tables, and association strength was quantified using the Ochiai Index. Researchers identified six coral life forms and four megabenthos types, producing 45 potential association combinations. Results indicated that 39 combinations exhibited no association. The remaining six showed associations, equally divided between positive and negative. Positive associations occurred between mushroom corals and Acanthaster planci, massive corals and Tridacna spp., and encrusting corals and Trochus spp. These relationships were identified as commensal, where species coexist without direct harm. Negative associations were found between massive and encrusting corals, encrusting corals and Tridacna spp., and encrusting corals and Diadema setosum. The Ochiai Index proved effective in detecting species interactions and supporting coral reef ecosystem assessments
The Effect of Adding Ecoenzyme to Corn-Based Trichoderma asperellum Formula on the Biomass of Rice Sprouts
Get PDFImproving rice productivity is a key priority to meet the increasing national food demand. This study aims to examine the effect of ecoenzyme addition to a Trichoderma asperellum-based corn medium on the biomass of rice seedlings of the Bujang Marantau variety. The research was conducted using a Completely Randomized Design (CRD) with five ecoenzyme concentration treatments (0%, 20%, 40%, 60%, and 80%) and five replications. Parameters observed were fresh weight and dry weight of seedlings after 14 days of treatment. Data were analyzed using ANOVA at a 5% significance level and followed by Duncan’s New Multiple Range Test (DNMRT). The results showed that ecoenzyme application did not significantly affect the fresh or dry weight of the rice seedlings. The highest fresh weight was found at 20% concentration, while the highest dry weight was at 80%. It is concluded that ecoenzyme has not demonstrated effectiveness in enhancing seedling biomass during the early growth stage, possibly because seedlings still rely on internal food reserves. The findings suggest that ecoenzyme may be more suitable for improving soil quality rather than directly stimulating early plant growth. Further research is recommended to optimize dosage, application methods, and appropriate growth stages for maximum benefit
