Abstract: Peningkatan ketahanan penetrasi menyebabkan pertumbuhan akar tanaman terhambat sehingga mengakibatkan penurunan produksi tanaman. Oleh karena itu, mempertahankan ketahanan penetrasi tanah agar tetap rendah merupakan salah satu syarat untuk mempertahankan produksi tanaman. Salah satu upaya yang dapat dilakukan untuk mempertahankan penetrabilitas tanah adalah pemberian bahan organik. Suatu penelitian yang bertujuan untuk mengetahui ketahahanan penetrasi tanah akibat penambahan bahan organik dengan dosis yang berbeda pada tanah Podsolik dan Latosol telah dilakuan di rumah kaca kebun Pendidikan Cikabayan IPB. Bahan organik berasal dari limbah industri perkebunan berupa limbah ekstraksi bromelin dan bambu cacah. Penelitian ini menggunakan rancangan acak lengkap yang terdiri atas dua perlakuan jenis tanah, dua perlakuan bahan organik dan lima perlakuan dosis bahan organik dengan inkubasi selama lima bulan. Hasil penelitian menunjukkan bahwa nilai ketahanan penetrasi tanah pada perlakuan bahan organik limbah ekstraksi bromelin dan bambu cacah selama lima bulan inkubasi belum berubah nyata. Nilai ketahanan penetrasi untuk tanah podsolik pada bulan pertama, ketiga dan kelima adalah berturut-turut berkisar 0.29-0.54 kg/cm2, 0.75-0.92 kg/cm2, 0.71-0.87 kg/cm2 sementara untuk Latosol adalah 0.33-0.71 kg/cm2, 0.54-0.88 kg/cm2, dan 0.46-0.79 kg/cm2. Ketahanan penetrasi akan meningkat dengan menurunnya kadar air, namun peningkatan ketahanan penetrasi akibat penurunan kadar air pada Podsolik lebih besar daripada Latosol.
Increased penetration resistance causes stunted plant root growth resulting in decreased crop production. Therefore, maintaining low penetration resistance is one of the efforts for maintaining crop production. One effort that can be done to maintain soil penetrability is the application of organic matter. A study aimed at determining soil penetrability as response to the addition of organic matter at different doses in Podzolic and Latosol soils was carried out in the greenhouse of the education garden Cikabayan IPB. The organic material used came from industrial plantation waste in the form of bromelain extraction waste and chopped bamboo. This study used a completely randomized design consisting of two treatments of soil type, two treatments of organic matter, and five doses of organic matter with incubation time for five months. The results showed that the value of soil penetrability in the treatment of organic matter from bromelain extraction waste and chopped bamboo with five months incubation had not changed significantly. Penetration resistence values for podzolic soils in the first, third, and fifth months ranged from 0.29-0.54 kg/cm2, 0.75-0.92 kg/cm2, 0.71-0.87 kg/cm2 respectively while for Latosol were 0.33-0.71 kg/cm2, 0.54- 0.88 kg/cm2, and 0.46-0.79 kg/cm2. Penetration resistance will increase with decreasing water content, but the increase in penetration resistance due to decreased water content in Podzolic is greater than that in Latosol.
