Jatropha (Jatropha curcas, L.) is an energy crop mainly cultivated for the oil-seed, and the oil is usually used as bio-fuel. However, few studies have reported information about the utilization of the wood as a fuel for boiler heating systems. With 2500 jatropha trees per hectare, it is possible to produce about 3 t·ha−1·y−1 of woody biomass from pruning. In addition, jatropha trees are commonly cut down to a height of 45 cm once every 10 years, with a production of 80 t·ha−1 of dry matter of woody biomass. The use of this biomass has not yet been investigated. During the European project JatroMed, woody biomass from jatropha pruning was collected in Morocco. Chemical and physical characteristics of the wood were conducted according to UNI EN ISO standards. The following jatropha wood characteristics have been analyzed: Moisture and ash contents, the ash melting point, heating value, and concentrations of C, H, N, and S. This research focused on the evaluation of the potential use of jatropha pruning for energy production, and the results represent critical data that is useful for future studies and business potential.

Indonesia memiliki banyak  tanah masam, tetapi penggunaan masih sangat sedikit karena kandungan nutrisi tanah masam rendah. Sementara itu, jarak pagar merupakan tanaman yang dapat tumbuh di berbagai jenis tanah (termasuk lahan marjinal) dan penggunaannya sebagai bahan baku biodiesel. Oleh karena itu, perlunya penelitian mengenai pertumbuhan jarak pagar pada tanah masam sebagai upaya untuk mengembangkan jarak pagar dan penggunaannya di Indonesia.Untuk memulai upaya, penelitian tentang berbagai genotipe jarak pagar di tanah masam telah dilakukan. Tujuan dari penelitian ini yaitu mempelajari genotipe jarak pagar  yang berpotensi untuk tanah masam. Penelitian ini dilakukan di UPTD Pengembangan Teknologi Lahan Kering Singabraja, Kecamatan Tenjo, Bogor, Jawa Barat, dari November 2010-Agustus 201. Penelitian ini menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) dengan satu faktor yaitu genotipe. Hasil penelitian menunjukkan berbagai perbedaan pada pertumbuhan diantara genotipe-genotipe jarak pagar. Secara umum, ada lima genotipe jarak pagar yang terbaik di tanah masam (pH 5.0) yaitu Medan I-5-1, Dompu, IP-2P-3-4-1, Sulawesi, dan Bima M.
