Metoda ekstraksi benih akan mempengaruhi mutu fisik dan fisiologis benih yang dihasilkan. Selain itu, mutu fisik dan fisiologis benih juga dipengaruhi oleh faktor ukuran benih. Penelitian ini bertujuan untuk mengetahui pengaruh metoda ekstraksi dan ukuran benih terhadap mutu fisik-fisiologis benih hasil pemuliaan dan yang belum dimuliakan untuk jenis A. crassicarpa. Ekstraksi benih dilakukan dengan cara pengeringan, yaitu dengan penjemuran di bawah sinar matahari dan menggunakan alat pengeringan (seed drier). Pengeringan dengan cara penjemuran di bawah sinar matahari dilakukan selama 1 s/d 5 hari dan dengan cara seed drier dilakukan selama 1 s/d 5 jam. Rancangan percobaan yang digunakan adalah Acak Lengkap. Sedangkan untuk mendapatkan klasifikasi ukuran benih A. crassicarpa berdasarkan dimensi benih (panjang, lebar, dan tebal) digunakan ayakan/mesh, dan klasifikasi berdasarkan berat digunakan alat Seed gravity Table. Hasil penelitian menunjukkan bahwa metoda ekstraksi dan ukuran benih yang terbaik untuk benih hasil pemuliaan dan yang belum dimuliakan, yaitu : (1) Ekstraksi benih dengan cara pengeringan seed drier selama 4 jam atau dengan cara penjemuran sinar matahari selama 3 hari dan (2) Benih yang berukuran besar dan paling berat memiliki viabilitas lebih baik dibandingkan dengan benih berukuran sedang, kecil dan ringan. Hasil penelitian juga menunjukkan bahwa benih hasil pemuliaan dapat menghasilkan mutu fisik fisiologis yang lebih baik dibandingkan dengan yang belum dimuliakan.

Kombinasi uji spesies-provenan jenis-jenis shorea penghasil tengkawang dibangun pada tahun 2011 di Stasiun Penelitian Meranti di Gunung Dahu, Bogor, Jawa Barat. Evaluasi dilakukan secara periodik setiap enam bulan selama 18 bulan untuk mengetahui kemampuan adaptasi dari jenis dan provenan yang diuji. Materi genetik yang digunakan adalah jenis-jenis shorea penghasil tengkawang (S. macrophylla, S. gybertsiana, S. stenoptera, S. pinanga) yang berasal dari 4 provenan (Gunung Bunga-Kalimantan Barat, Sungai Runtin-Kalimantan Barat, Bukit Baka-Kalimantan Tengah, dan Haurbentes-Jawa Barat). Penelitian menggunakan Rancangan Acak Lengkap Berblok (RCBD) dengan 11 plot, 4 ulangan, 25 pohon per plot (5 x 5 pohon) dan jarak tanam 5 x 5 meter. Sifat yang diukur adalah persen hidup dan tinggi tanaman pada umur 6,12 dan 18 bulan. Hasil analisis menunjukkan bahwa persen hidup tidak berbeda nyata, dan pertumbuhan tinggi tanaman menunjukkan perbedaan yang nyata. Jenis-jenis shorea pengasil tengkawang (S. macrophylla, S. pinanga dan S. stenoptera) dari ras lahan Haurbentes (Jawa Barat) menunjukkan pertumbuhan terbaik sampai dengan umur 18 bulan.

The purpose of this research is to utilized and provide added value from dregs seed of nyamplung solid waste through composting process using several starters, and findout the compost chemical character. The research was design as randomized complete (CRD) with 4 types of starters as treatments (biostarter of cattle rumen contents, Prouponic Gb # 1, EM4, Primadec C-15) each with 3 replications. Analysis of 7 chemical properties parameters carried out on nyamplung dregs seed before and after the treatment included: pH, DHL, organic C, total N, C / N ratio, Total P, and total K by comparing to SNI No.19- 7030-2004. The results showed that DHL, C / N ratio, total N, P, and total K of dregs seed compost fulfilled the SNI. The type of starter treatments significantly affected the quality of nyamplung dregs seed compost (DHL, total N, P, and K levels). Types of starters showing the best results were Prouponic Gb # 1 and EM4 compared to other biostarters. Therefore, Prouponic Gb # 1 and EM4 were reccomended to be applied to process nyamplung dregs seed waste into high quality compost.Keywords: biostarter, dregs seed, compost, solid waste, nyamplung

Calophyllum inophyllum L. is one of species that has been identified as a source of oil suitable for biofuel, cosmetics and medicine. Until now, the propagation of this species uses generative methods. In the forest tree breeding program, after a plus tree is selected a vegetative propagation technique must be developed to maintain the genetic potential of the parent tree. This study was conducted to determine the growth response of selected clones in Provenance Seed Stand of C. inophyllum in Wonogiri, Central Java propagated using the grafting method. The research used was arranged in Randomized Completely Design with 22 clones as the parent tree treatments. Each treatment consisted of 5 grafted seedlings and repeated in 4 times. The results showed that the survival percentage of grafted seedlings ranges from 15 – 100 % at 2 months of age, which showed a fairly high variation among the selected clones. Increasing the success of the grafting technique on the C. inophyllum clones still needs to be done so that it can provide vegetative material for clone testing and operational planting. It is important to be conducted in order to produce C. inophyllum stands with high fruit productivity and oil yield.Keywords: Calophyllum inophyllum, vegetative propagation, seedling growth, nursery
