Abstract

The need for peanuts from year to year continues to increase in line with the increasing population, community nutrition needs, food diversification, and the increasing capacity of the feed and food industry in Indonesia. N, P, and K are important factors and must be available to plants because they function as metabolic and biochemical processes of plant cells. Nitrogen is used as a builder of nucleic acids, proteins, bioenzymes, and chlorophyll. The purpose of this study was to determine the effect of NPK fertilizer on the growth and production of peanut plants. This research was conducted from January 2023 to April 2023 at the Faculty of Agriculture, Graha Nusantara University Padangsidimpuan. The method in this research is Non Factorial Randomized Group Design (RAK) with 4 types of calcium fertilizer treatments: 0 g/polybag (C0), 3 g/polybag (C1), 5 g/polybag (C2) and 7 g/polybag (C3). The results showed that NPK fertilizer affected the number of pods, pod weight and seed weight. The calcium fertilizer treatment that gives the best results on soybean crop production is in the C2 treatment, namely a dose of 5 3 g / polybag.

Abstract

This community service program aims to optimize the utilization of home gardens through the development of ginger (Zingiber officinale) cultivation in Pargarutan Dolok Village, South Tapanuli Regency. The activity was implemented in response to the low productivity of village home gardens, which are generally underutilized for economic purposes. The implementation method employed a participatory approach involving local residents directly through stages of socialization, training, demonstration plot establishment, technical assistance, and program sustainability evaluation. A total of 42 families actively participated out of 60 targeted households, with a plant growth success rate of 92%. The application of liquid organic fertilizer and botanical pesticides effectively increased the number of shoots and reduced the incidence of plant diseases. The social impact showed an 85% improvement in community awareness and skills in utilizing home gardens, along with the formation of the “Jahe Sejahtera Pargarutan” group as a collaborative business platform. Economically, the potential additional household income from 50 ginger polybags reached IDR 270,000–360,000 per planting cycle. The results of this program demonstrate that optimizing home garden land through ginger cultivation can significantly enhance household welfare and food security while promoting economic independence among rural communities.
