Abstract

Pakchoy is a leafy vegetable that is great demand by Indonesians. The increase in population has had a major impact on agricultural land, which has encouraged an urban farming system, using polybags for crop production. The use of soil media in polybags often experiences compaction and lack of nutrients, so it is necessary to modify the composition of the planting media and put additional fertilization. This research was conducted to evaluate the response of pakchoy to local microorganisms based on rice waste and to determine the best composition of growing medium for pakchoy plants. This study used a completely randomized design (CRD) with 2 factors. The first factor was the local microorganism (LMO) doses of rice waste consisted of 4 levels, namely 0 ml, 500 ml, 1000 ml, and 1500 ml per plant. The second factor was the composition of the planting medium (Soil : Sand: Cow Manure) at 4 levels, namely Soil 100%, 1:1:1, 1:1:2, 1:1:3. Data were statistically analyzed with ANOVA at 5% level. Mean separation was tested further with Duncan Multiple Range Test. The results showed that the LMO 0 ml and 500 ml performed higher effects on plant height, number of leaves, plant fresh and dry weight, root fresh and dry weight, and root length compared to the application LMO at 1000 ml and 1500 ml. The highest plant fresh weight was 193.1 g at 0 ml LMO, followed by 160.35 g at 500 ml LMO.   The composition of the planting medium 1:1:1 and 1:1:2 resulted in a higher number of leaves, plant dry weight, and root weight than other treatments. Incorporating a high portion of manure into the pakchoy planting medium was not beneficial. All growth variables and yield were higher compared to the control medium (soil 100%).  Key Words: pakchoy, local microorganism,  planting media

Abstract

Entisols, comprising approximately 10.6% of Indonesia's land area, are youthful soils distinguished by sandy texture, loose structure, ample aeration porosity, rapid permeability, low water retention, and diminished organic matter. This study determines the optimal dosages of liquid organic fertilizer and cow manure capable of enhancing the physical attributes of Entisols and the growth and yield of sweet corn plants. Employing a Randomized Complete Block Design (RCBD) with two factors, the research evaluates three doses of cow manure (0 tons ha-1, 5 tons ha-1, and 10 tons ha-1) and four concentrations of liquid organic fertilizer (0 mL L-1, 100 mL L-1, 200 mL L-1, and 300 mL L-1). The findings reveal that liquid organic fertilizer significantly influenced soil wet weight and pF pressure at 0.1 atm (12.68 g-1). Application of cow manure demonstrates tangible improvements in Entisols properties, with water content at 12.15%, bulk density at 0.73 g m-3, permeability at 90.57 cm hour-1, and soil wet weight and pF pressure at 0.1 atm (15.10 g). Furthermore, liquid organic fertilizer contributes to a plant height of 176.82 cm and husk cob weight of 8,545 kg ha-1, while cow manure results in a plant height of 174.05 cm and husk cob weight of 8.044 kg ha-1. The optimal combination emerged with a 300 mL L-1 concentration of liquid organic fertilizer or a 10 tons ha-1 dose of cow manure,  showcasing superior enhancements in Entisols' physical properties, as well as sweet corn plant growth and yield.

Abstract

Rice cultivation faces challenges due to limited land availability despite increasing demand. Utilizing swamp land for cultivation presents an alternative, albeit hindered by difficult-to-control water conditions and less effective fertilizer spread. To ensure optimal nutrient supply, foliar application of Azolla liquid organic fertilizer (LOF) is explored. This study investigates the ideal concentration and frequency of Azolla LOF application for rice growth and yield. Employing a split plot design, the main plot assesses LOF concentration (3%, 6%, 9%, 12%), while the subplot evaluates application frequency (1, 2, 3 times). Results indicate that a 9% LOF concentration yields the highest tiller count (17.99), longest panicle (25.788 cm), highest grain count per panicle (158.2978), heaviest grain weight per hill (45.878 g), and highest grain weight per plot (3457.52 g). However, the fastest flowering period (54 DAP) occurs with a 12% LOF concentration. Applying Azolla LOF three times achieves the earliest flowering (55.25 DAP), while two applications yield the longest panicle (25.03 cm). Notably, no interaction is observed between LOF concentration and application frequency on rice growth and yield. These findings provide insights into optimizing Azolla LOF application for enhanced rice cultivation in swamp lands.

Abstract

This research was a classroom action research aiming to improve students' learning outcomes and speaking skills through the Examples Non Examples method. This research was conducted at grade III of SDN 010 Bayas Jaya, Indragiri Hulu. The subjects in this research were 28 third-grade students of SDN 010 Bayas Jaya. The research results obtained that the percentage of students' speaking skills after implementing the Example Non-Example method in the second cycle was 86.75% or classified as "very good" because it was in the range of 80%- 100%. Thus, in the second cycle, the students' speaking skills were said to be improved or better because they reached the KKM of 70. Moreover, implementing the Example NonExample method increased the students' learning activity. Finally, this research found progressin the students' speaking skills at grade III of SDN 010.
