<![CDATA[Abstrak: Keadaan tanah desa Anjir kabupaten Pulang Pisau didominasi lahan gambut yang memiliki kendala tinggi untuk budidaya hortikultura, seperti tingkat kemasaman (pH) rendah dan kandungan unsur hara yang minim. Kegiatan Pengabdian kepada Masyarakat (PkM) ini bertujuan untuk meningkatkan kapasitas petani dan produktivitas semangka melalui penerapan teknologi ramah lingkungan kepada 25 anggota kelompok Tani “Pelangi Nusantara (MAHIKAT)” di Desa Gohong, Kecamatan Kahayan Hilir, Kabupaten Pulang Pisau. Selain itu, metode pelaksanaan PkM meliputi pelatihan teknis, pendampingan, dan implementasi demplot percontohan seluas 0,8 ha yang menerapkan teknologi spesifik gambut (pengapuran, amelioran kompos, irigasi terkontrol). Evaluasi selama kegiatan PkM dilakukan untuk memantau keaktifan peserta dan progres demplot melalui observasi langsung, wawancara dan diskusi dengan mitra serta dokumentasi kegiatan. Sedangkan evaluasi pada akhir kegiatan dilakukan untuk menilai hasil dan dampak program melalui analisis produksi, survei kepuasan dan persepsi mitra serta evaluasi keberlanjutan usaha. Hasil kegiatan menunjukkan peningkatan pemahaman petani sebesar 42%, terjadi peningkatan produktivitas semangka 40-55% (dari 18-20 menjadi 28 ton/ha), dan peningkatan pendapatan bersih petani sebesar 65%. Simpulan dari kegiatan ini adalah model teknologi budidaya ramah lingkungan terbukti efektif meningkatkan produktivitas dan ekonomi petani di lahan gambut dan dilakukan program pendampingan berkelanjutan.Abstract: The soil conditions in Anjir Village, Pulang Pisau Regency, are dominated by peatlands that pose significant challenges for horticultural cultivation, such as low acidity levels (pH) and minimal nutrient content. This Community Service (PkM) activity aims to enhance farmer capacity and watermelon productivity through the application of environmentally friendly technologies to 24 members of the "Pelangi Nusantara (MAHIKAT)" Farmer Group in Gohong Village, Kahayan Hilir District, Pulang Pisau Regency. The implementation methods include technical training, mentoring, and the establishment of a 0.8-hectare demonstration plot applying peatland-specific technologies (liming, compost ameliorant, controlled irrigation). Evaluation during the activity was conducted to monitor participant engagement and demonstration plot progress through direct observation, interviews and discussions with partners, and activity documentation. Meanwhile, evaluation at the end of the activity was performed to assess the results and program impact through production analysis, satisfaction and perception surveys with partners, and business sustainability evaluation. The results show a 42% increase in farmer understanding, a 40-55% increase in watermelon productivity (from 18-20 to 28 tons/ha), and a 65% increase in farmer net income. The conclusion of this activity is that the environmentally friendly cultivation technology model has proven effective in improving productivity and farmer economics in peatlands, and a sustainable mentoring program was implemented.]]>
