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.

Abstract

Semangka (Citrullus lanatus) merupakan komoditas hortikultura yang memiliki nilai ekonomi tinggi dan banyak diminati konsumen. Salah satu indikator kualitas buah semangka adalah warna daging buah yang menarik. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian hormon giberelin terhadap kualitas warna daging buah semangka. Penelitian dilaksanakan menggunakan rancangan acak kelompok (RAK) non-faktorial yang terdiri atas empat taraf konsentrasi giberelin, yaitu G0 = 0 ppm, G1 = 100 ppm, G2 = 200 ppm, dan G3 = 300 ppm dengan enam ulangan. Parameter yang diamati adalah warna daging buah menggunakan Royal Horticultural Society (RHS) Colour Chart. Hasil penelitian menunjukkan bahwa pemberian hormon giberelin mampu meningkatkan intensitas warna merah daging buah semangka. Perlakuan G0 menghasilkan warna 47D Red Pink, perlakuan G1 menghasilkan warna 42B Medium Red, sedangkan perlakuan G2 dan G3 menghasilkan warna 45B Dark Red. Hasil tersebut menunjukkan bahwa pemberian giberelin pada konsentrasi 200 ppm dan 300 ppm menghasilkan warna merah daging buah yang lebih pekat dibandingkan perlakuan lainnya. Dengan demikian, aplikasi hormon giberelin berpotensi meningkatkan intensitas warna merah daging buah semangka.
