      Abstract
      Kopi merupakan salah satu komoditas perkebunan yang memegang peranan penting di Indonesia. Penelitian ini dilakukan dengan metode observasi untuk mengidentifikasi jenis dan jumlah biji gulma, dinamika spesies gulma, serta faktor-faktor yang mempengaruhi pertumbuhan gulma pada berbagai umur tanaman kopi. Analisis data yang digunakan adalah uji F dan uji korelasi. Diketahui jumlah tertinggi terdapat pada umur 4 tahun dengan jumlah benih mencapai 549 individu, umur 1 tahun (260 individu) dan umur 41 tahun (303 individu). Benih gulma yang dominan adalah Cynodon dactylon pada umur 1 dan 4 tahun, sedangkan umur 41 tahun adalah Ageratum houstonianum. Hasil uji F menunjukkan umur tanaman berpengaruh dengan jumlah seed bank dan umur yang paling berbeda nyata adalah tanaman kopi berumur 4 tahun. Umur tanaman tidak berpengaruh nyata dengan seed bank. Hasil korelasi menunjukkan bahwa faktor lingkungan yang mempengaruhi jumlah biji gulma atau keberadaan biji gulma adalah suhu, pH H2O, pH KCL, kandungan C-organik, total nitrogen (N), fosfor tersedia (P), dan K-dd.
       
      Coffee is a plantation commodity that plays an important role in Indonesia. This study was conducted using observational methods to identify the types and number of weed seeds, the dynamics of weed species, and factors that influence weed growth at various ages of coffee plants. Data analysis used F tests and correlation tests. It was found that the highest number of seeds was found at 4 years of age with the number of seeds reaching 549 individuals, 1 year of age (260 individuals) and 41 years of age (303 individuals). The dominant weed seeds were Cynodon dactylon at ages 1 and 4 years, while at 41 years of age were Ageratum houstonianum. The results of the F test showed that plant age had an effect on the number of seed banks and the age with the most significant difference was the 4 year old coffee plant. Plant age had no significant effect on the seed bank. The correlation results showed that environmental factors that influence the number of weed seeds or the presence of weed seeds were temperature, pH H2O, pH KCl, C-organic content, total nitrogen (N), available phosphorus (P), and K-dd.
