Abstract
This research was conducted using a factorial randomized block design (RBD) method, which consists of two treatment factors, namely: 1) Aspirin administration factor with growth inhibitors with a notation (A) consists of 4 levels of treatment, namely: A0 = Control (without administration) Aspirin); A1 = administration of Aspirin at a dose of 1.25 g / l of water; A2 = Giving Aspirin at a dose of 2.50 g / l water, 2) Factors for giving cabbage waste compost with a notation (K), consisting of 3 levels of treatment, namely: K0 = Control (without giving cabbage waste compost); K1 = Giving cabbage waste compost at a dose of 10 tons / ha; K2 = Giving cabbage waste compost at a dose of 20 tons / ha, each treatment was repeated 3 (three) times. The parameters observed in this study were plant height, number of leaves, leaf color, stem diameter, number of tubers and production weight. As for the results obtained from this study, namely: 1) Giving Aspirin has a very significant effect on plant height, number of leaves, number of tubers and weight of production, but no significant effect on leaf color and stem diameter; 2) Giving cabbage waste compost has a very significant effect on plant height, number of leaves, number of tubers and weight of production, but no significant effect on leaf color and stem diameter; and 3) The combination of aspirin and cabbage waste compost has a very significant effect on the number of tubers and production weight, but has no significant effect on plant height, number of leaves, leaf color and stem diameter.

Penelitian ini dilaksanakan dengan menggunakan metode Rancangan Acak Kelompok (RAK) Faktorial, yang terdiri dari dua faktor perlakuan, yaitu : 1) Faktor pemberian zat penghambat tumbuh Aspirin dengan notasi (A) terdiri dari 4 taraf perlakuan, yaitu : A0 = Kontrol; A1 = Pemberian Aspirin dengan dosis 1,25 g/l air; A2 = Pemberian Aspirin dengan dosis 2,50 g/l air, 2) Faktor pemberian kompos limbah kubis dengan notasi (K), terdiri dari 3 taraf perlakuan, yaitu : K0 = Kontrol; K1= Pemberian kompos limbah kubis dengan dosis 10 ton/ha; K2 = Pemberian kompos limbah kubis dengan dosis 20 ton/ha, masing-masing perlakuan diulang sebanyak 3 kali
which consists of two treatment factors
The parameters observed in this study were plant height
Summary
Lokasi penanaman kentang yang paling baik adalah tanah bekas sawah karena hama dan penyakit berkurang akibat sawah selalu berada dalam kondisi anaerob. Kegiatan persiapan lahan tanaman kentang hingga siap tanam dilakukan melalui beberapa tahap. Tahap awal dari kegiatan tersebut adalah perencanaan yang meliputi penentuan arah bedengan, terutama pada lahan berbukit, pembuatan selokan, pemeliharaan tanaman dan pemupukan. Tahap berikutnya adalah pengolahan tanah dengan cara pembajakan atau pencangkulan sedalam kurang lebih 30 cm hingga gembur, kemudian diistirahatkan selama 1-2 minggu. Pengolahan tanah dapat diulangi sekali lagi hingga tanah benarbenar gembur sambil meratakan tanah dengan garu atau cangkul untuk memecah bongkahan tanah berukuran besar. Setelah pembajakan tanah dan penggemburan dilakukan pembuatan bedengan dan selokan untuk irigasi atau pengairan. Selanjutnya di sekeliling petak-petak bedengan dibuat selokan untuk pembuangan air (drainase) sedalam 50 cm dengan lebar 50 cm. Seminggu sebelum penanaman dilakukan pemberian pupuk dasar berupa pupuk kandang dan pupuk TSP. Pupuk kandang diberikan sebanyak 20 kg/plot dan pupuk TSP sebanyak 300 kg/plot (Lehar, 2012)
