Abstract

Soil fertility decline and sulfur deficiency are major constraints in shallot (Allium ascalonicum L.) cultivation, especially in sandy soils with low cation exchange capacity. Biochar and rice husk ash are potential soil amendments known to improve soil structure, nutrient availability, and crop productivity. This study aimed to determine the effect of rice husk biochar and rice husk ash on the growth, yield, and sulfur uptake of shallots. A factorial experiment was conducted using a Randomized Group Design (RGD) with two factors: biochar and rice husk ash, each at three dose levels. Results showed that biochar application improved the number of leaves, number of tillers, and bulb weight per unit, while rice husk ash had a limited effect, mainly enhancing leaf number at early growth. No significant interaction between the two amendments was observed across measured parameters, including sulfur uptake. These findings suggest that biochar contributes more effectively to shallot growth and yield than rice husk ash under the tested conditions. Further studies are recommended to optimize the combined use of organic amendments and to explore their long-term effects on soil nutrient dynamics and crop performance.

Abstract

Social stigma can encourage people to hide their illness so that they are not discriminated against, prevent them from seeking medical assistance immediately, and prevent them from carrying out healthy lifestyle behaviors without realizing it will cause more transmission to others. The aim of the study was to carry out a phenomenological survey of social interventions to reduce the stigma against WUS in breaking the chain of transmission of Covid-19 in the working area of the Medan Helvetia Health Center. The target to be achieved from this research is the formation of cooperation in tackling the transmission of Covid-19 which involves all community leaders, especially WUS. The research was carried out in Helvetia District, the working area of the Helvetia Health Center, Medan City. The research method was carried out using a qualitative approach. The qualitative approach used is participatory action research. The research procedures to be carried out are engagement/intake, data collection and need assessment (phenomenological survey), model formulation, intervention and monitoring and evaluation and termination. Data collection methods were carried out by sharing, in-depth interviews, (FGD) and questionnaires. Interactive model analysis is used to analyze qualitative data on phenomenological surveys and the process of conducting participatory action research. The results of the research, the phenomenological survey generally closed oneself when exposed to Covid-19, did not tell neighbors, friends or family but after recovering they were told, with the aim of not being ostracized or avoided by the local community. The FGD was conducted to look at the problems found in the phenomenological survey, and the results of the discussion resulted in a social intervention, namely the training of the Covid-19 Task Force as counselees in reducing the stigma of Covid-19, carried out for 3 days. Implementation of participatory action research requires a long time to be able to see changes in behavior and social change, for this reason further research is needed to see the persistence of interventions carried out by the Covid-19 Task Force.

Abstract

This study aims to determine the production of soybeans with the application of mycorrhizal biological fertilizers and P fertilizers on the production of soybeans (Glycine max L. Meriil). This experiment was carried out at the Experimental Garden of the Faculty of Agriculture, Indonesian Methodist University, from August–October 2018. This study used a Randomized Block Design (RAK) consisting of Mycorrhiza (M) namely M0: 0 g/plant (control); M1: 5 g/plant; M2: 10 g/plant; M3: 15g/plant and Fertilizer (P), namely P0: 0 g/plant (control); P1:0.25 g/plant; P2: 0.5 g/plant; P3: 0.75 g/plant. All treatment combinations were 12 combinations and each treatment combination was repeated 3 times. Variables observed in this study include: flowering age (days); seed production per sample (g); seed production per plot (g); dry weight of 100 seeds (g). The experimental results showed that the interaction between mycorrhizal application and application of NPK fertilizer had a significant effect on seed production per sample, seed production per plot, dry weight of 100 seeds and not significantly different with flowering age. The highest seed production per sample was found in the M3P3 treatment of 26.32 g, the highest seed production per plot was found in the M3P2 treatment of 161.80 g and the highest dry weight of 100 seeds was found in the M3P3 treatment of 25.60 g. The mycorrhizal biofertilizer application treatment showed that the fastest flowering time was found in the M3 treatment, namely 36.58 days and 36.92 days in the P (P3) fertilizer treatment.

Abstract

This study aims to determine the effect of fruit pruning and application of Potassium on the growth and production of strawberry plants (Fragaria chiolensis). This study used a randomized block design (RBD) with 2 factors. The first factor was fruit pruning consisting of 4 levels: P0 = No pruning, P1 = 1 pruning, P2 = 2 pruning, P3 = 3 pruning. The second factor is Potassium fertilizer consisting of 4 levels: K0 = 0 g/plant, K1 = 2 g/plant, K2 = 4 g/plant, K3 = 6 g/plant. The observed variables were plant height (cm), flowering age (days), Fruit Weight (g), Fruit Volume (cm3), Sugar Content (%), Plant Wet Weight (g), and Plant Dry Weight (g). The results showed that pruning three fruits/plant increased plant height, fruit weight, fruit volume, sugar content, fresh weight and dry weight. Applying potassium fertilizer up to a dose of 6 g/plant can increase plant height, flowering time, fruit weight, fruit volume, sugar content, and wet and dry weight. Meanwhile, the interaction between fruit pruning and potassium application had no significant effect on all observed parameters.

Abstract

This research aims to determine the effect of a combination of NASA POC and chicken manure on the growth and production of sweet corn (Zea mays saccharata Sturt). The research used a Randomized Group Design (RAK) with two treatment factors. The first factor is the administration of NASA Liquid Organic Fertilizer (A) consisting of 4 treatment levels, namely: A0 = 0 ml/liter of water (control), A1 = 2 ml/liter of water, A2 = 4 ml/liter of water and A3 = 6 ml /liter of water. The second factor is the provision of chicken manure (B) consisting of 3 treatment levels, namely: B1 = 2.25 kg/plot (7.5 tons/ha), B2 = 4.50 kg/plot (15 tons/ha) and B3 = 6.75 kg/plot (22.5 tons/ha). The results showed that giving NASA POC up to 6 ml/l of water significantly increased plant height, ear length, ear weight per plot and total dissolved solids. Providing chicken manure up to 6.75 kg/plot significantly increased plant height, ear length, weight per plot and total soluble solids. The interaction between NASA POC and chicken manure did not significantly affect plant height, ear length, weight per plot, or total dissolved solids.
