The provision of compost from Oil Palm Empty Fruit Bunch (OPEFB) by Addition
of of various doses of boiler ash is expected to optimize the utilization of palm oil
mill effluent to increase the fertility of Ultisols and increase the growth of corn
plants. This study aims to determine the use of OPEFB compost and boiler ash to
improve soil chemical properties and growth of maize (Zea mays L.) on Ultisol
soil, carried out on the land at Pasar 1, Tanjung Sari, Medan Selayang subdistrict
and soil analysis at the Research Laboratory, Faculty of Agriculture, University
of North Sumatera, starting from October 2019 to completion. This study used a
non-factorial randomized block design consisting of 7 levels of treatment K0
(control), K1 : (100 g OPEFB compost + 5 g boiler ash ), K2( 100 g OPEFB
compost + 10 g boiler ash), K3( 100 g OPEFB compost + 15 g boiler ash), K4
(100 g OPEFB compost + 20 g boiler ash), K5 (100 g OPEFB compost + 25
boiler ash), K6 (100 g OPEFB compost + 30 g boiler ash). The treatment was
repeated 4 (four) times. The results of this study indicate that the application of
TKKS compost enriched with various doses of boiler ash can, increase pH, levels
of C-organic, N-total, and K-exchange of Ultisol soil, but, can’t increase KTK of
Ultisols and the growth of corn plants. Pemberian kompos Tandan Kosong Kelapa Sawit (TKKS) dengan penambahan
berbagai dosis abu boiler diharapkan dapat mengoptimalkan pemnafaatan
limbah pabrik kelapa sawit untuk meningkatkan kesuburan tanah Ultisol dan
meningkatkan pertumbuhan tanaman jagung. Penelitian ini bertujuan untuk
mengetahui pemanfaatan kompos TKKS dan abu boiler terhadap perbaikan sifat
kimia tanah dan pertumbuhan tanaman jagung ( Zea mays L. ) pada tanah
Ultisol, dilaksanakan di lahan Jalan Pasar 1, Tanjung Sari, Kecamatan Medan
Selayang dan analisis tanah di Laboratorium Riset, Fakultas Pertanian,
Universitas Sumatera Utara, mulai dari bulan Oktober 2019 sampai dengan
selesai. Penelitian ini menggunakan Rancangan Acak Kelompok Non- Faktorial
yang terdiri dari 7 taraf perlakuan K0 (control ), K1 : (100 g kompos TKKS + 5 g
abu boiler ), K2( 100 g kompos TKKS + 10 g abu boiler), K3( 100 g kompos
TKKS + 15 g abu boiler), K4 (100 g kompos TKKS + 20 g abu boiler), K5 (100 g
kompos TKKS + 25 g abu boiler), K6 (100 g kompos TKKS + 30 g abu boiler).
Setiap perlakuan diulang sebanyak 4 ( Empat ) kali. Hasil penelitian ini
menunjukkan bahw pemberian kompos TKKS yang diperkaya berbagia dosis abu
boiler meningkatkan pH, kadar C-organik, N-total, dan K-tukar tanah Ultisol.
namun, tidak meningkatkan KTK tanah Ultisol dan pertumbuhan tanaman
jagung.
