Respon Pertumbuhan Sukun (Artocarpus communis F.) Terhadap Berbagai Ketebalan Mulsa Spons dan Interval Penyiraman

ABSTRACT
FATHIN HANANA HARAHAP: Response of Breadfruit(Artocarpus communis
F.)Growth Toward Various ofSponges MulchThickness and Watering Interval.
Under supervision: BUDI UTOMO and AFIFUDDIN DALIMUNTHE.
Utilization of mulch on the forestry sector has not been widely applied,
both organic mulch or non-organic mulch. This research aimed to determine the
effect of sponge mulch various thickness and watering intervals on the growth of
breadfruit seeds (Artocarpus communis F.) in the greenhouse. This research uses
a completely randomized design 2 factorial. Each seedling given 6 treatment for
sponges mulch thickness and 4 treatments for watering interval.Mulching sponge
treatment against the breadfruit plants provide significant effect on several
parameters were observed, among other things: height, diameter, number of
leaves and leaf area. Watering interval treatment againts the breadfruit plants
provide significant effect on several parameters were observed, among other
things: height, diameter, number of leaves, leaf area, root dry weight and shoot
dry weight. Interaction between mulching sponge treatment with watering interval
treatment against the breadfruit plants provide significant effect on several
parameters were observed, among other things: height, diameter, number of
leaves, leaf area, and spacious canopy.
Keywords: Artocarpus communis, mulch, sponges, watering interval

Pertumbuhan
Sukun
(Artocarpus communis F.) Terhadap Berbagai Ketebalan Mulsa Spons
dan Interval Penyiraman. Dibimbing oleh BUDI UTOMO dan AFIFUDDIN
DALIMUNTHE.
Pemanfaatan mulsa pada bidang kehutanan belum banyak diaplikasikan,
baik mulsa organik maupun mulsa non organik. Penelitian ini bertujuan
untukmengetahui pengaruh pemberian berbagai ketebalan mulsa spons dan
interval penyiraman terhadap pertumbuhan bibit sukun di rumah kaca.Penelitian
ini menggunakan metode Rancangan Acak Lengkap (RAL) 2 faktorial. Masingmasing bibit diberi 6 perlakuan untuk ketebalan dan 4 perlakuan untuk interval
penyiraman. Perlakuan pemberian mulsa spons terhadap tanaman sukun
memberikan pengaruh nyata terhadap beberapa parameter yang diamati, antara

lain: tinggi, diameter, jumlah daun, dan luas daun.Perlakuan penyiraman terhadap
tanaman sukun memberikan pengaruh nyata terhadap beberapa parameter yang
diamati, antara lain: tinggi, diameter, jumlah daun, luas daun, bobot kering akar
dan bobot kering tajuk. Interaksi antara perlakuan pemberian mulsa spons dengan
penyiraman terhadap tanaman sukun memberikan pengaruh nyata terhadap
beberapa parameter yang diamati, antara lain: tinggi, diameter, jumlah daun, luas
daun, dan luas tajuk.
Kata Kunci : Artocarpus communis, mulsa, spons, interval penyiraman
