Abstract

Prostate disease is a significant health concern affecting men, particularly those over 35 years old. This community service activity aimed to increase knowledge and awareness about prostate disease among the congregation of GMI Manna Helvetia Medan through health education. The methods included educational presentations, motivational sessions, and question-and-answer discussions. The activity was attended by 45 participants aged 35-70 years. Results showed improved participant understanding of prostate disease symptoms, risk factors, and the importance of early detection. About 70% of participants committed to undergo prostate examination within the next 6 months. The educational approach through church community proved effective in delivering sensitive health information and raising awareness about the importance of regular check-ups.

Abstract

This study aims to determine the effect of chicken manure and liquid organic fertilizer on shallots (Allium cepa L.). This study used a Randomized Group Design (RAK) with 2 factors. The first factor is chicken manure consisting of 4 levels, namely: K0 = Control (without treatment), K1 = 1.83 kg/plot (equivalent to 15 tons/Ha), K2 = 2.44 kg/plot (equivalent to 20 tons/Ha) and K3 = 3.05 kg/plot (equivalent to 25 tons/Ha). The second factor is POC consisting of 3 levels, namely: P1 = 3 ml/240ml water/plant, P2 = 6 ml/240ml water/plant and P3 = 9 ml/240ml water/plant. Data analysis used analysis of variance and Duncan test. The results showed that chicken manure had a significant effect on plant height, number of leaves, number of tubers per sample, number of tubers per plot, wet tuber weight per sample, wet tuber weight per plot, dry tuber weight per sample and dry tuber weight per plot. Increasing the dose of manure will increase the growth and production of shallot plants. Chicken manure has a significant effect on plant height, number of leaves, dry bulb weight per sample and dry bulb weight per plot, but has no significant effect on the number of bulbs per sample, number of bulbs per plot, wet bulb weight per sample, wet bulb weight per plot. Chicken manure had a significant effect on the dry weight of bulbs per plot, but had no significant effect on plant height, number of leaves, number of bulbs per sample, number of bulbs per plot, wet bulb weight per sample, wet bulb weight per plot and dry bulb weight per sample.

Abstract

Shallot production in Indonesia has not been able to meet market needs due to the scarce availability of subsidized chemical fertilizers. Another alternative to replacing chemical fertilizers can be using Liquid Organic Fertilizer. The aim of this research was to determine the effect of watering time and concentration of liquid organic fertilizer on the growth and production of shallots (Allium ascalonicum L.). The design in this study was a Randomized Block Design (RAK), consisting of 2 treatment factors, namely watering time (W) consisting of 2 treatment levels, namely: W1= 1x1 week, W2= 1x2 weeks and POC concentration (P) consisting of 4 treatment levels namely: P1= 2 ml/240 ml water/plant, P2= 4 ml/240 ml water/plant, P= 6 ml/240 ml water/plant and P4= 8 ml/240 ml water/plant. Data analysis uses analysis of variance, if the treatment factor has a significant effect on the variance test, a mean difference test is carried out using the Duncan Multiple Range Test (DMRT) at 5% level. The results showed that POC watering time had a significant effect on tuber diameter and number of tubers per sample, but had no significant effect on fresh weight of tubers per sample and dry weight of tubers per sample. POC concentration had a significant effect on tuber diameter, number of tubers per sample, fresh weight of tubers per sample and dry weight of tubers per sample.

Abstract

The study aims to determine the effect of foliar fertilizer on the growth and production of several varieties of mustard greens (Brassica juncea L). This study used a Factorial Randomized Block Design (RAK) consisting of two factors. The first factor is mustard greens varieties (V) consisting of 3 levels: V1 = Tosakan variety, V2 = Shinta variety, and V3 = Dora variety. The second factor is foliar fertilizer (P), consisting of 3 levels: P0 = control, P1 = 2 cc / l of water, and P2 = 4 cc / l of water. The parameters observed in this study were plant height and wet and dry Weight of plants. The results showed that the variety treatment significantly affected plant height, wet Weight and dry Weight of mustard greens. The highest growth and production were obtained in variety V1 (Tosakan), followed sequentially by variety V2 (Shinta) and variety V3 (Dora). Foliar fertilizer treatment significantly affected plant height, wet Weight and dry Weight of mustard greens. The higher the concentration of leaf fertilizer given up to 4 cc/l of water, the higher the growth and production of mustard plants. The interaction between variety treatment and leaf fertilizer concentration had no significant effect on all observed variables.

Abstract

This research was conducted in Sei Beras Sekata Village, Sunggal District, Deli Serdang Regency, North Sumatra Province. With an altitude of ± 25 meters above sea level. This study aimed to determine the response of rice growth (Oryza sativa L) to the provision of cow manure and liquid fertilizer. The design used was a Randomized Block Design (RAK) Factorial with the main treatment being solid organic fertilizer (A) with three treatments, namely L1 = (660 gr / Plot) 3 tons / Ha, L2 = (1100 gr / Plot) 5 tons / Ha, L3 = (1650gr / Plot) 7.5 tons / Ha. Organic fertilizer 3 treatments, namely, K1 = 2.5cc / liter, K2 = 5cc / liter, K3 = 7cc / liter. The parameters observed in this study were plant height per clump (cm), number of tillers per clump (stem), and number of productive tillers per clump (stem). The study showed that solid organic fertilizer treatment had no significant effect on all parameters. In contrast, liquid organic fertilizer significantly affected the number of productive shoots but did not significantly affect plant height per clump (cm) and number of shoots per clump (stems).

Abstract

One of the organic waste processing technologies is Eco Enzyme. Eco enzyme is a complex solution of light to dark brown color, which has a fresh sour aroma. Organic waste, in the form of fruit peels, unused fruit flesh, and vegetable pieces, is collected in containers/barrels and then mixed with molasses/brown sugar and water with a certain dose. The recommended dose for the ratio of molasses: organic waste: water is 1:3:10. The fermentation results produce environmentally friendly enzymes and other beneficial elements for agriculture. This study aims to determine the nutrient content of P2O5, K2O, and the C/N ratio of eco enzymes derived from various organic materials. This study used a non-factorial, completely randomized design (CRD). This study used 6 treatment combinations consisting of: P1 = Musa paradisiaca L Boobs (1.5 kg) + Tithonia diversifolia Leaves (1.5 kg); P2 = Musa paradisiaca L weevil (1.5 kg) + Terminalia catappa leaves (1.5 kg); P3= Musa paradisiaca L Weevil (1.5 kg) + Spreading Leaf Shoots (1.5 kg); P4= Mimosa pudica Root (1.5 kg) + Tithonia diversifolia Leaf (1.5 kg); P5 = roots of Mimosa pudica daughter (1.5 kg) + Terminalia catappa leaves (1.5 kg); P6 = Roots of Mimosa pudica (1.5 kg) + Shoots of Spreading Leaves (1.5 kg). The results showed that using organic materials significantly affected the K2O content and the C/N ratio of the eco enzyme.

Abstract

Dormancy is a state of stopping growth experienced by plants. This research aimed to determine the concentration of KNO3 solution in breaking dormancy in several papaya varieties. The research method used in this research was a completely randomized design (RAL) Factorial with 2 treatment factors. The first factor is variety (V), consisting of V1 = Callina, V2 = California, and V3 = Local. The second factor is the concentration of the KNO3 (K) solution consisting of: K0 = Control, K1 = 10%, K2 = 20% and K3 = 30%. The variables observed were growth synchrony and germination speed index. Data analysis uses analysis of variance. The variables observed were growth synchrony and germination speed index. An analysis of variance was used to test the effect of treatment. To test mean differences between treatments, honest significant difference tests, regression, and correlation were carried out at a test level of 5%. The research results showed that seed variety had a significant effect on growth synchrony and germination speed index. The concentration of KNO3 solution has a significant effect on growth synchrony and germination speed index. The interaction between the variety and concentration of KNO3 solution had no significant effect on all observed parameters.
