Abstract

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

Abstract

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
