ABSTRAK Limbah sagu di samping dapat dimanfaatkan sebagai sumber bahan organik juga potensial digunakan sebagai amelioran dan herbisida nabati. Penelitian bertujuan untuk mengetahui pengaruh limbah sagu dan cara penyiangan gulma terhadap populasi gulma dan pertumbuhan lada perdu. Penelitian dilaksanakan di Kebun Percobaan (KP) Institut Pertanian Bogor (IPB) dan Laboratorium Balai Penelitian Tanaman Obat dan Aromatik Balittro) dari bulan Mei 2003 sampai April 2004. Penelitian menggunakan rancangan petak terbagi yang disusun secara faktorial. Cara penyiangan gulma (S) sebagai petak utama dan komposisi limbah sagu (L) sebagai anak petak. Susunan perlakuan sebagai berikut: S 1 = penyiangan bersih dan S 2 = penyiangan terbatas. Komposisi limbah sagu terdiri dari L 0 = tanpa bahan organik; L 1 = 100% limbah sagu, L 2 = 100% limbah sagu, dekomposisi 1 bulan, L 3 = 100% limbah sagu dekomposisi 2 bulan; L 4 = 75% limbah sagu + 25% kompos; L 5 = 75% limbah sagu + 25% kompos, dekomposisi 1 bulan; L 6 = 75% limbah sagu + 25% kompos, dekomposisi 2 bulan; L 7 = 50% limbah sagu + 50% kompos; L 8 = 50% limbah sagu + 50% kompos, dekomposisi 1 bulan; L 9 = 50% limbah sagu + 50% kompos, dekomposisi 2 bulan; L 10 = 25% limbah sagu + 75% kompos; L 11 = 25% limbah sagu + 75% kompos, dekomposisi 1 bulan; dan L 12 = 25% limbah sagu + 75% kompos, dekomposisi 2 bulan. Hasil penelitian menunjukkan bahwa kandungan limbah sagu 75% limbah sagu + 25% kompos dekomposisi 2 bulan meningkatkan pertumbuhan dan produktivitas lada perdu. Limbah sagu dengan 100% dalam bentuk segar dan dekomposisi sampai 2 bulan efektif dalam menekan populasi gulma.

The objective of the research was to find out the effect of sago palm waste and weeding method on the growth of dwarf pepper and weed population. The research was conducted at the experimental garden of the Bogor Agriculture Institute and the Indonesian Medicinal and Aromatic Crops Research Institute from May 2003 to April 2004. The research was arranged factorially in split-plot design. The main plot was weeding methods (S) and a composition of sago palm waste (L) as the sub plot. The treatments were as follows: S 1 = clean weeding and S 2 = limited weeding. The composition of sago waste were Lo = non organic matter; L 1 = 100% sago waste; L 2 = 100% sago waste of one month decomposition; L 3 = 100% sago waste of two months decomposition ; L 4 = 75% sago waste + 25% compost; L 5 = 75% sago waste + 25% compost of one month decomposition; L 6 = 75% sago waste + 25% compost of two months decomposition; L 7 = 50% sago waste + 50% compost; L 8 = 50% sago waste 50% compost of one month decomposition; L 9 = 50% sago waste + 50% compost of 2 months decomposition; L 10 = 25% sago waste + 75% compost’ L 11 = 25% sago waste + 75% compost of one month decomposition; and L 12 = 25% sago waste + 75% compost of two months decomposition. The result showed that the composition of 75% sago waste + 25% compost of two months decomposition increase the growth and productivity of dwarf pepper. The fresh (75 - 100%) sago palm waste of one month decomposition was effective in decreasing weed population. Key words : Sago palm waste, weed, bushy black pepper
