<p>Indonesian society has a consumption pattern dominated staple grains group. To reduce dependence on other countries for imports of foodstuffs, need to diversification their meal using existing biodiversity. One of the crops that can be developed is the cocoyam (Xanthosoma spp.) potential as a source of carbohydrate. Cocoyam can be grown in the lowland to the mountains with a height of up to 1300 meters above sea level. Therefore it is necessary to find the most appropriate planting site so that plants can grow and develop optimally. This study aimed to determine the growth of three types of new cocoyam at a different altitude variation. This study was conducted in two different regions of altitude, is Tawangmangu (1200 m above sea level) and Klaten (98 m above sea level). Observations using three different types of cocoyam, the tuber white, purple and yellow. Each type grown in both altitude with 10 replications each. The observations were obtained include fresh weight, dry weight, number of leaves, chlorophyll and carotenoid levels were analyzed by unpaired t test and ANOVA test at 95% confidence level. The results of this study indicate that tuber white, purple and yellow tuber are planted in the lowlands (Klaten) and highlands (Tawangmangu) had significant results in the measurement of plant height, fresh weight, dry weight, and chlorophyll and carotenoid levels have significantly different results, but not the parameters of the number of leaves. Height and weight of the fresh plant<br />in Klaten higher than in Tawangmangu, while the white tuber dry weight in Tawangmangu higher than other treatments. The levels of chlorophyll and carotenoid yellow tuber is the highest in Klaten than others.</p>

ABSTRAK Pengeloaan Kebun Raya Baturraden di Kawasan Hutan Produksi terbatas dapat menimbulkan permasalahan surface run off apabila penanganan lokasi tidak dilakukan secara konservatif. Penelitian ini bertujuan untuk mengatasi problematika Perubahan ekositem Hutan Produksi Terbatas yang bersifat homogen menjadi Kebun Raya Baturraden merupakan hutan heterogen. Dengan cara membuat PU (Petak Ukur) di zona pemanfaatan keluasan 77,4 Ha, sebanyak 109 PU (Petak Ukur) dengan ukuran 20x20 m, intensitas 5,5, jarak antar PU 1, 3 m. Hasil pengamatan   parameter yang menjadi pertimbangan ketinggian tanah antara 1076-760 Dpl, kelerengan tanah 12⁰-30⁰, kedalaman tanah < 85 Cm – 90<, erodibilitas tanah 0,43, jenis tanah Latosol Coklat dan curah hujan rata-rata 5.600 mm per tahun. Dari hasil pengamatan kawasan Kebun Raya Baturraden tanah mudah sekali terjadi   proses surface run off. Mengatasi dan merubah ekosistem dari hutan homogeny menjadi heterogen (1) penjarangan harus bertahap sesuai lahan yang akan dikelola, (2) Dengan kondisi tegakan pohon sangat rapat untuk melakukan tebangan sebaiknya menggunakan tebangan penerangan atau penjarangan jangan sampai tanah terbuka mengingat mempunyai curah hujan rata-rata 5.600 mm per tahun. (3) pada lokasi tertentu yang rawan terjadi erosi harus dibuat terasering untuk mengurangi terjadinya surface run off.   Kata Kunci: Kebun Raya, Hutan Produksi terbatas surface run off, ekosistem ABSTRACT Managing Baturraden Botanical Garden in the Limited Production Forest Area can cause problems of surface run off if the location is not handled conservatively. This study aims to overcome the problem of ecosystem changes of the homogeneous Limited Production Forest to become Baturraden Botanical Garden which is heterogeneous forest by making PU (sample plots) in the utilization zone of 77.4 hectares in breadth, a total of 109 PU (sample plots) with a size of 20x20 m, intensity of 5.5, the distance between PU’s 1, 3 m. The parameters taken into consideration, as a result of observation, are the height of land between 1076-760 above sea level, land slope between 30⁰ 12⁰, land depth <85 cm - 90 <, soil erodibility 0.43, Brown Latosol soil type and an average rainfall of 5,600 mm per year. From the observation of Baturraden Botanical Garden area, it was observed that land surface run off processes easily occur. To overcome and change the ecosystem of the forest, from homogeneous to heterogeneous: (1) thinning should be phased in accordance to the land to be managed, (2) with the condition of very tight tree stands to be felled, lighting felling or thinning should be done without exposing the land considering the rainfall average of 5,600 mm per year. (3) In certain locations that are prone to erosion terracing must be made to reduce the occurrence of surface run-off.   Key words: Botanical Garden, limited production forest, surface run-off, ecosystem.
