description: ZPT dapat diartikan sebagai senyawa yang mempengaruhi proses fisiologi  tanaman, pengaruhnya dapat mendorong dan menghambat proses fisiologi  tanaman. Salah satu ZPT yang dapat digunakan adalah ethrel dengan bahan aktif  ethepon. Pengaplikasian ethepon mengakibatkan pertumbuhan tanaman  terhambat. Pada penelitian ini digunakan stek ubi kayu varietas Thailand dan  Kasetsart berukuran 25 cm yang berumur 8-12 bulan. Tujuan penelitian ini adalah  untuk: (1) mengevaluasi pengaruh konsentrasi ethepon yang berpengaruh terhadap  penghambatan pertumbuhan dua varietas tanaman ubi kayu, (2) mengevaluasi  pengaruh varietas terhadap produksi dan pertumbuhan tanaman ubi kayu, (3)  menentukan konsentrasi ethepon pada dua varietas ubi kayu yang berpengaruh  terhadap penghambatan pertumbuhan dan peningkatan produksi. Perlakuan  disusun secara fakorial (8 x 2) dalam Rancangan Acak Kelompok (RAK) dengan  4 ulangan yang dijadikan sebagai kelompok, setiap kelompok terdiri dari 16 sub  Artati Sriwardani Tumanggor  sampel. Faktor pertama dalam penelitian ini adalah perlakuan berbagai  konsentrasi ethepon, yaitu 0; 0,5; 1; 1,5; 2; 2,5; 3 dan 3,5 ml/l. Faktor kedua  adalah jenis varietas, yaitu Thailand dan Kasetsart. Ethepon diberikan melalui  daun saat tanaman telah berumur 60 hari sebanyak 50 ml per tanaman dengan  variabel pengamatannya adalah tinggi tanaman, jumlah daun segar, jumlah buku,  bobot basah daun, batang, dan ubi, dan bobot kering daun, batang, dan ubi.  Pemberian 2,5 ml ethepon/l mampu menghambat tinggi tanaman 4 MSA,  pemberian 3,5 ml ethepon/l mampu mengurangi jumlah daun segar 2 MSA pada  varietas Thailand, pemberian 3,5 ml ethepon/l mampu meningkatkan jumlah daun  segar 4 MSA pada konsentrasi 3,5 ml/l. Pemberian 3,5 ml ethepon/l mampu  menghambat jumlah buku 4 MSA, dan pemberian 2,5 ml ethepon/l mampu  menurunkan bobot basah dan kering ubi. Pada hasil penelitian, aplikasi ethepon  tidak meningkatkan produksi, baik varietas Thailand maupun Kasetsart.  Kata kunci: Ethepon, penghambatan, tanaman ubi kayu, varietas    ABSTRACT  Growth inhibition can be interpreted as a compound that affects the plant  physiology process, its influence can stimulate and inhibit the physiology of  plants. One of the growth inhibition that can be used to inhibit growth is ethrel  with ethepon active ingredient. This research used the Thailand and Kasetsart  varieties of cassava cuttings with 25 cm length and age of 8-12 months. The  purposes of this study were to: (1) evaluate the effect of ethepon concentration  which influenced the inhibition of growth of two varieties of cassava plant, (2)  evaluate the effect of varieties on cassava production and growth,(3) determine  ethepon concentrations in two varieties of cassava affecting growth inhibition and  increased production. The treatments were arranged factorially (8 x 2) in a  Randomized Block Design (RBD) with 4 replicationused as a block, each block  Artati Sriwardani Tumanggor  consists of 16 sub samples. The first factor was the treatment of eight different  ethepon concentrations as 0; 0,5; 1; 1,5; 2; 2,5; 3;and 3,5 ml/l. The second factor  is two types of cassava varieties as is Thailand and Kasetsart. Ethepon was  applied through leaves when the plants are 60 days after planting with the volume  of 50 ml per plant. Variables observed in this research are plant height; number of  fresh leaves; number of books; wet weight of leaves, stems, and roots; and dry  weight of leaves, stems, and roots. The application of 2,5 ml ethepon/l was able  to inhibit plant height at 4 Weeks After Application (WAA). More over, the  application of 3,5 ml ethepon/l was able to reduce the amount of fresh leaf at 2  WAA of Thailand variety. However, the application of 3,5 ml ethepon/l could  increase the number of fresh leaves at 4 WAA. The application of 3,5 ml  ethepon/l could inhibit the number of books at 4 WAA. Then the application of  2,5 ml ethepon/l was able to reduce the weight of wet and dry roots. In this  research, ethepon application could not increase the production of both varieties  as Thailand and Kasetsart.  Keywords: cassava, ethepon, growth inhibition, varieties.
