Penelitian ini bertujuan untuk mengetahui pengaruh dari pemberian ketiga jenis
zat pengatur tumbuh IBA, NAA, IAA dan lama perendaman serta interaksi antara
keduanya terhadap pertumbuhan stek rumput pakchong. Penelitian ini
dilaksanakan pada November 2022--Januari 2023, dilakukan di Laboratorium
Lapang Terpadu Fakultas Pertanian Universitas Lampung dan Laboratorium
Nutrisi dan Makanan Ternak, Jurusan Peternakan, Fakultas Pertanian Universitas
Lampung. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) pola
faktorial yang terdiri dari 3 taraf perlakuan yaitu P1 (IBA 300 ppm), P2 (NAA
200 ppm), P3 (IAA 200 ppm) dan faktor lama perendaman terdiri dari 3 taraf
perlakuan yaitu L1 (lama perendaman 1 jam), L2 (lama perendaman 3 jam), L3
(lama perendaman 5 jam) dengan 3 kali ulangan. Variabel yang diamati meliputi
persentase tumbuh, jumlah anakan, jumlah daun, tinggi tanaman, produksi bobot
segar, produksi bahan kering, kandungan bahan kering. Data yang diperoleh
dianalisis menggunakan Sidik Ragam (Analysis of Variance) dan dilanjutkan
dengan uji BNt (Beda Nyata terkecil). Hasil penelitian pemberian jenis zat pengatur
tumbuh dan lama perendaman menunjukkan bahwa interaksi perlakuan tidak
berpengaruh nyata (P{\ensuremath{>}}0,05) terhadap persentase tumbuh dan kandungan bahan
kering serta tidak ada pengaruh antara kedua perlakuan. Hasil penelitian pemberian
jenis zat pengatur tumbuh dan lama perendaman menunjukkan bahwa adanya
interaksi serta berpengaruh sangat nyata (P{\ensuremath{<}}0,05) terhadap jumlah anakan dan
jumlah daun pada perlakuan NAA dengan lama perendaman 1 jam (P2L1), serta
pada tinggi tanaman, produksi bobot segar dan produksi bahan kering terdapat
pada perlakuan IBA dengan lama perendaman 1 jam (P1L1).

This research aims to determine the effect of the three types of growth regulators
IBA, NAA, IAA and the soaking time and the interaction between the two on the
growth of pakchong grass cuttings. This research was conducted in November
2022--January 2023, conducted at the Integrated Field Laboratory, Faculty of
Agriculture, University of Lampung and the Animal Feed and Nutrition
Laboratory, Department of Animal Husbandry, Faculty of Agriculture, University
of Lampung. This study used a factorial completely randomized design (CRD)
consisting of 3 treatment levels, namely P1 (IBA 300 ppm), P2 (NAA 200 ppm),
P3 (IAA 200 ppm) and the soaking time factor consisting of 3 treatment levels,
namely L1 (soaking time 1 hours), L2 (soaking time 3 hours), L3 (soaking time 5
hours) with 3 replications. Variables observed included growth percentage,
number of tillers, number of leaves, plant height, fresh weight production, dry
matter production, dry matter content. The data obtained were analyzed using
Sidik Variety (Analysis of Variance) and continued with the BNt (Smallest
Significant Difference) test. The results of the study showed that the application
of growth regulator and soaking time showed that the treatment interaction had no
significant effect (P{\ensuremath{>}}0.05) on the percentage of growth and dry matter content and
there was no effect between the two treatments. The results of the study of giving
the type of growth regulator and soaking time showed that there was an
interaction and had a very significant effect (P{\ensuremath{<}}0.05) on the number of tillers and
the number of leaves in the NAA treatment with 1 hour soaking time (P2L1), as
well as on plant height, weight production fresh and dry matter production found
in IBA treatment with 1 hour soaking time (P1L1).
