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.

ABSTRAK
FATHIN HANANA HARAHAP: Respon 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. Masing-masing 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
