Abstract
The purpose of this research was to analyze the diversity of weed vegetation during the generative phase of bitter melon (Momordica charantia L.) cultivation and to determine the dominant weed species in the farmland of the Jabon Adiasa Mandiri Farmer Group, located in Serang City, Banten. This research was conducted using a quadrat sampling method with a 1×1 m2 plot size applied to 10 sample distributed systematically across the research area. Data collected included the type of weed species, number of individuals, density, frequency, and dominance. These parameters were used to calculate the Important Value Index (IVI) and Summed Dominance Ratio (SDR) for each species. The results showed that the weed vegetation in the study area consisted of 16 species belonging to 13 families, with a total of 569 individual weeds. The broadleaf weed group was the most dominant in terms of composition, followed by grasses, sedges, and narrow-leaf types. The Asteraceae family had the highest number of species, while Rottboellia cochinchinensis (Poaceae) was identified as the most dominant weed species based on its highest SDR value. Environmental factors such as high light intensity, moderate humidity, and open land conditions contributed to the high level of weed diversity. The presence of dominant weeds indicates a strong potential for competition with the main crop, particularly in terms of nutrients, water, and sunlight. The results of this study can serve as a reference for implementing integrated weed management strategies that are ecologically based and sustainable, especially for bitter melon cultivation in similar agroecosystems.

| Additional Information: | Analisis Keragaman Vegetasi Gulma pada Tanaman Paria (Momordica charantia L.) Fase Generatif di Lahan Kelompok Tani Jabon Adiasa Mandiri Kota Serang. Dibimbing oleh Nurmayulis dan Ratna Fitry Yenny Penelitian ini berfokus pada identifikasi dan analisis jenis-jenis gulma yang terdapat di lahan pertanaman paria (Momordica charantia L.), tanaman semusim dari famili Cucurbitaceae yang banyak dibudidayakan di wilayah tropis, termasuk Indonesia. Meskipun paria dikenal memiliki nilai ekonomi dan manfaat kesehatan yang tinggi, keberadaan gulma di sekitar tanaman dapat menurunkan produktivitas akibat persaingan dalam memperoleh unsur hara, air, dan cahaya. Penelitian dilaksanakan di lahan kelompok tani Jabon Adiasa Mandiri, Kota Serang, serta Laboratorium Ilmu Dasar dan Perlindungan Tanaman, Fakultas Pertanian, Universitas Sultan Ageng Tirtayasa. Metode yang digunakan dalam penelitian ini adalah analisis vegetasi kuantitatif dengan teknik pengambilan sampel menggunakan kuadrat berukuran 1×1 m² sebanyak 10 unit secara acak. Parameter yang diamati meliputi kerapatan, frekuensi, dan dominansi gulma. Selanjutnya, data dianalisis untuk menentukan Indeks Nilai Penting (INP) dan Summed Dominance Ratio (SDR) guna mengidentifikasi jenis gulma dominan di lokasi penelitian. Hasil penelitian menunjukkan terdapat 16 jenis gulma yang berasal dari 13 famili, dengan total individu sebanyak 569. Famili Asteraceae, Poaceae, dan Cleomaceae mendominasi komunitas gulma di lahan pertanaman paria. Jenis Rottboellia cochinchinensis tercatat sebagai gulma paling dominan dengan nilai SDR tertinggi yaitu 25,35%. Keanekaragaman gulma yang ditemukan dipengaruhi oleh kondisi lingkungan terbuka, kelembaban, intensitas cahaya, serta teknik budidaya. Temuan ini memberikan informasi penting bagi petani dalam merancang strategi pengendalian gulma terpadu yang efektif dan berkelanjutan untuk mendukung peningkatan produktivitas tanaman paria. | ||||||||||||
