Penelitian ini memilikki tujuan untuk mengetahui pengaruh jarak tanam dan dosis kompos ampas kopi terhadap pertumbuhan dan produksi bawang merah. Penelitian ini menggunakan Rancangan Acak Kelompok pola faktorial 4 x 3 dengan 3 ulangan. Faktor yang diteliti yaitu jarak tanam yang terdiri dari 3 taraf (yaitu 10 cm x 15 cm, 15 cm x 25 cm, dan 20 cm x 30 cm) dan dosis kompos ampas kopi yang terdiri dari 4 taraf (kontrol, 15, 30, dan 45 ton ha-1). Hasil penelitian menunjukkan bahwa jarak tanam berpengaruh sangat nyata terhadap potensi hasil. Produksi tanaman terbaik dijumpai pada perlakuan jarak tanam 10 cm x 20 cm. Dosis kompos ampas kopi berpengaruh sangat nyata terhadap tinggi tanaman umur 2, 4, dan 6 MST, diameter umbi, bobot kering umbi per rumpun, dan produksi tanaman. Pertumbuhan dan hasil bawang merah terbaik dijumpai pada perlakuan kontrol (tanpa kompos). Terdapat interaksi yang sangat nyata terhadap tinggi tanaman 2, 4, dan 6 MST, diameter umbi, bobot kering umbi per rumpun dan interaksi nyata terhadap potensi hasil. Pertumbuhan dan produksi bawang merah terbaik dijumpai pada kombinasi perlakuan jarak tanam 10 cm x 20 cm dengan perlakuan kontrol (tanpa kompos ampas kopi).

This study aims to find out the effect of planting distance and the dose of coffee pulp compost on the growth and production of onions. The study used a Randomized Design Group of 4 x 3 factorial patterns with 3 repeats. Factors studied were planting distance consisting of 3 levels (i.e. 10 cm x 15 cm, 15 cm x 25 cm, and 20 cm x 30 cm) and a dose of coffee pulp compost consisting of 4 levels (control, 15, 30, and 45 tons ha-1). The results showed that planting distance has a very real effect on the potential of results. The best potential results are found in the treatment of planting distance of 10 cm x 20 cm. The compost dose of coffee grounds has a very noticeable effect on the height of plants aged 2, 4, and 6 WAP, bulb diameter, dry weight of bulbs per clump, and potential yield. The best onion growth and results are found in the control treatment (without compost). There is a very noticeable interaction with plant height of 2, 4, and 6 WAP, bulb diameter, dry weight of bulbs per clump and real interaction of potential yields. The best growth and production of onions is found in the combination of 10 cm x 20 cm planting distance treatment with control treatment (without coffee grounds compost).
