PENINGKATAN PRODUKSI DAN ANALISIS KELAYAKAN USAHA PADI SAWAH DENGAN SISTEM PENGELOLAAN TANAMAN TERPADU (PTT)
Abstrak: This study aims to
determine the growth and productivity of low land rice, Inpari 14 variety
managed under the integrated farming system (PTT) and to conduct its
feasibility analysis with the same system.
The research used Randomized Block Design (RBD) non factorial consisting
of 9 treatments and 3 replications. The
treatments used, namely: control (“square” style of plant spacing 20cm x 20cm,
transplanting 17 days after sowing, 3 seedlings per planting hole, and no
manure); PTT 1 (square plant spacing 20cm x 20cm, transplanting 15 days after
sowing, one seedling per planting hole, and 1 t ha-1 manure); PTT 2 (“legowo
style” of plant spacing of 2:1, transplanting 15 days after sowing, planting
one seedling per planting hole, and 1 t ha-1 manure); PTT 3 (square plant
spacing of 20cm x 20cm, transplanting 15 days after sowing, 2 seedlings, and 1
t ha-1 manure); PTT 4 (legowo spacing of 2:1, transplanting 15 days after
sowing, planting 2 seeds per planting hole, and 1 t ha-1 manure); PTT 5 (square
planting spacing of 20cm x 20cm, transplanting 15 days after sowing, planting
one seed per planting hole , and 2 t ha-1 manure); PTT 6 (legowo spacing 2:1,
transplanting 15 days after sowing, planting one seed per planting hole, and 2
t ha-1 manure); PTT 7 (square planting spacing of 20cm x 20cm, transplanting 15
days after sowing, 2 seeds per planting hole, and 2 t ha-1 manure), and PTT 8
(legowo spacing of 2:1, transplanting 15 days after sowing, 2 seeds per
planting hole, and 2 t ha-1 manure).
Results showed that an increase in production of 0.9 t ha-1 or 17.33
percent of the rice attained by PTT 8 treatment compared to the control with
each production 5.25 t ha-1 and 4.34 t ha-1.
There were trends that the dried husk rice results ha-1 of legowo
cropping systems, namely PTT 2 (4.96 t ha-1), PTT 4 (5.21 t ha-1) , PTT 6 (4.13
t ha-1), and PTT 8 (5.25 t ha-1) had a higher yield than the PTT tile systems
treatment, namely PTT 1 (3.18 t ha-1); PTT3 ( 4.13 t ha-1); PTT 5 (4.17 t
ha-1), and PTT 7 (4.19 t ha-1). The PTT
8 treatment gave profit per hectare of Rp. 16,171,057 (Sixteen Million One
Hundred Seventy One Thousand Fifty Seven Rupiah) that was higher compared to
control of Rp. 13,002,557 (Thirteen Million Two Thousand Five Hundred Fifty
Seven Rupiah) that mean the PTT 8 treatment provided increased revenue by 20%
