Abstract

Training on making planting media for polybags was held in Sanggrahan, Wonorejo, Gondangrejo, Karanyanyar, and Central Java. The activity was held on June 3, 2023, and was attended by women from PKK RT 05 RW 18. The characteristic of Sanggrahan is almost the same as that of other urban areas, namely the lack of land for cultivating plants. The aim of this activity is to provide insight to PKK women about urban agriculture so that the remaining land in urban areas can still be cultivated using a polybag system. Residents can manage small areas of land to grow vegetable crops so that they can reduce their daily household expenditure on vegetables. To produce optimal plant growth, cultivation in polybags requires appropriate planting media that are easy for residents to make. The method of service activities involves providing material counseling and practical training on making planting media for polybags. We train participants on using easily available materials to create planting media. The materials used to make planting media are humus soil, compost, and husk charcoal in a ratio of 1:1:1. All ingredients are mixed evenly, then put into a polybag. Vegetable seeds that are ready to plant are put into polybags, and then regular maintenance is carried out so that they grow optimally. The size of the polybag varies depending on the type of plant being planted. To support the success and sustainability of this activity, regular evaluation and monitoring are carried out. The aim of this community service is that residents can meet their household vegetable needs by making planting media that is easy to obtain in polybags.

Abstract

Black potato (Plectranthus rotundifolius) is a potential alternative food crop to substitute rice. However, its low productivity in Indonesia currently averaging around 15 tons/ha is influenced by factors such as sub-optimal nutrient supply and limited availability of high-quality planting materials. This study aims to examine the effect of applying seaweed extract as a biostimulant along with NPK fertilizer (16-16-16) on the growth and yield of black potato. The research was conducted at the Experimental Farm of the Faculty of Agriculture, UNISRI, Surakarta (130 m a.s.l.). A 4 x 4 factorial Completely Randomized Design (CRD) with three replications (totaling 48 experimental units) was employed. The first factor was the dosage of seaweed extract (0, 1, 2, and 3 mL/L), and the second factor was the NPK dosage (0, 200, 400, and 600 kg/ha). Data were analyzed using Analysis of Variance (ANOVA) followed by Honestly Significant Difference (HSD) test at the 5% significance level. The results showed a significant interaction between seaweed extract and NPK fertilizer on plant height, with the best combination observed at 3 mL/L seaweed extract and 600 kg/ha NPK (34.6 cm). Meanwhile, no interaction was found for the number of branches; however, each single factor had a significant effect. The single treatment of 3 mL/L seaweed extract produced the highest number of branches (15.5 branches), while 600 kg/ha NPK alone yielded 15.1 branches.
