Abstract

ABSTRACT Ultisol has quite a large potential in the development of agricultural cultivation, but in its management Ultisol experiences obstacles, namely its poor physical properties. The low content of organic matter in Ultisol soil causes the soil structure to break easily, so that aggregate stability becomes unstable. The stability of soil aggregates is very important in agricultural activities, stable soil aggregates will indicate good conditions for soil and plant growth. Given the importance of aggregate stability in the soil, one effort to improve aggregate stability is by providing organic matter in the form of solid decanter compost and municipal waste compost. This study used a Randomized Block Design (RAK) with a factorial pattern where the 1st factor was the solid decanter dose consisting of D0 without decanter, D1 10 tons / ha, D2 15 tons / ha and the 2nd factor was the dose of municipal waste compost consisting of K1 10 tons / ha, K2 15 tons / ha. This experiment consisted of 6 treatment combinations with 2 replications so that 12 experimental plots were obtained. The size of the experimental plot was 2.5 mx 2 m with a planting distance of 50 cm x 50 cm so that the number of plants in one plot was 9 plants. The results of the study showed that in the provision of solid decanters and municipal waste compost, no interaction was found in all observation variables. However, there was a single factor of solid decanters that had a significant effect on C-organic, weight volume, total pore space, aggregate stability, percentage of aggregate formed, and porang tuber yield, but the single factor of municipal waste compost showed no difference. Keywords: Ultisol, aggregate stability, solid decanter compost, municipal waste compost, porang. INTISARI Ultisol mempunyai potensi yang cukup besar dalam pengembangan budidaya pertanian, akan tetapi dalam pengelolaannya Ultisol mengalami kendala yaitu sifat fisiknya yang kurang baik. Rendahnya kandungan bahan organik pada tanah Ultisol menyebabkan struktur tanah mudah pecah, sehingga kestabilan agregat menjadi tidak stabil. Kemantapan agregat tanah sangat penting pada kegiatan pertanian, agregat tanah yang stabil akan menyatakan kondisi yang baik bagi tanah dan pertumbuhan tanaman. Mengingat pentingnya kemantapan agregat dalam tanah, maka salah satu upaya untuk memperbaiki kemantapan agregat adalah dengan pemberian bahan organik berupa kompos dekanter solid dan kompos sampah kota. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan pola faktorial dimana faktor ke-1 adalah dosis dekanter solid yang tediri dari D0 tanpa dekanter, D1 10ton/ha, D2 15 ton/ha dan faktor ke-2 adalah dosis kompos sampah kota yang terdiri dari K1 10ton/ha, K2 15 ton/ha. Percobaan ini terdiri dari 6 kombinasi perlakuan dengan 2 ulangan sehingga didapatkan 12 petak percobaan. Ukuran petak percobaan 2,5 m x 2 m dengan jarak tanam 50 cm x 50 cm sehingga jumlah tanaman dalam satu petak yaitu 9 tanaman. Hasil penelitian menunjukan bahwa pada pemberian dekanter solid dan kompos sampah kota tidak ditemukannya interaksi pada semua variabel pengamatan. . Namun terdapat faktor tunggal dekanter solid yang berpengaruh nyata pada C-organik, bobot volume, total ruang pori, kemantapan agregat, persen agregat terbentuk, dan hasil umbi porang namun pada faktor tunggal kompos sampah kota tidak menunjukan perbedaan.
