Abstract

Acacia crassicarpa improved seed has a higher quality than unimproved seed. To maintain the viability, improved seeds are required as appropriate handling techniques. One of the important steps in seed handling is seed germination test. A. crassicarpa seed have dormancy and to break it needs spesific pretreatment. Germination test can be worked in the laboratory and greenhouse. The purpose of this research was to obtain pretreatment and germination method better to maintain the viability of A. crassicarpa improved seed. Pretreatment in resources were without treatment, soaking in hot water (100oC ) and followed by soaking for 24 hours in cold water, soaking for 1 minute in hot water (100oC) followed by soaking for 24 hours in cold water, soaking for 6 minutes in hot water (100oC) followed by soaking for 24 hours in cold water, soaking for 30 minutes in H2SO4, torn of seedcoat, and torn of seedcoat and then soaking for 24 hours in cold water. Laboratory Germination method were top of paper (TP), between paper (BP), and pleated paper (PP) test. Whereas growing media used in greenhouse were top soil, sand, a mixture of top soil and sand (1:1/v:v), and cocopeat. The results showed that to maintain the viability of A. crassicarpa improved seed required the best pretreatment technique and germination methods were (1) in laboratory used combine between torn of seedcoat and top of paper. In this method, the percent of seed germination reached 96 %, and (2) in greenhouse used combine between torn of seedcoat and cocopeat. In this method, the percent of seed germination reached 88 %.

Abstract

Buah tengkawang merupakan salah satu hasil hutan bukan kayu bernilai tinggi dan merupakan salah satu komoditi eksporsebagai bahan baku lemak nabati, industri kosmetik, dan substitusi lemak coklat. Indonesia memiliki sekitar 13 spesies pohon penghasil tengkawang yang tersebar di Kalimantan dan sebagian kecil di Sumatera, namun sebagian besar telah masuk dalam kategori terancam punah. Untuk tindakan konservasi dan meningkatkan kandungan lemak nabati tengkawang, perlu diketahui potensi kandungan lemak dan sifat fisiko kimia dari setiap spesies dan provenan. Buah tengkawang dikoleksi pada saat musim panen raya spesies shorea penghasil tengkawang pada tahun 2010 di Kalimantan dan Jawa. Analisis kandungan lemak nabati tengkawang dilakukan terhadap empat spesies shorea penghasil tengkawang (S. macrophylla, S. gysbertsiana, S. stenoptera, S. pinanga) yang berasal dari empat provenans dan ras lahan (Gunung Bunga dan Sungai Runtin-Kalimantan Barat, Bukit Baka-Kalimantan Tengah, Haurbentes-Jawa Barat). Sebelas kombinasi spesies-provenan diambil sampel buahnya untuk diekstrasi guna mengetahui kandungan lemak dan sifat fisiko kimia tengkawang (kadar air, bilangan asam, dan kadar asam lemak bebas). Terdapat keragaman yang tinggi di antara kombinasi spesiesprovenans tengkawang untuk empat parameter yang diuji, termasuk kandungan lemak dan kadar air biji tengkawang. Kandungan lemak tertinggi dengan kadar air terendah dihasilkan oleh S. stenoptera dari Haurbentes (Jabar) dan S. pinanga dari Bukit Baka (Kalimantan Tengah). Kedua kombinasi spesies-provenan tersebut direkomendasikan sebagai materi genetik untuk dikembangkan dalam program konservasi eks-situ dan program pemuliaan tanaman hutan dalam pembangunan sumber benih unggul pada kondisi lingkungan yang hampir sama dengan kedua provenans dan ras lahan tersebut.Variation in Illipe Nut's Fat Yield of Tengkawang-producing Shorea from Several Provenances and Land RacesAbstractIllip (tengkawang) nut is a non-wood forest product which has a high economic value and one of export commodities as raw material for illipe nut's fat, cosmetics, and substitution of chocolate fat. Indonesia has 13 species of tengkawang-producing shorea distributed in Kalimantan and some small parts of Sumatra. Most of them are categorized as threatened species. To conserve and improve the species for illip nut's fat, it is important to assess the potential of fat yield and physical-chemical properties for each species and provenance. Fruit collection was conducted during fruit season in Kalimantan and Java in 2010. The fruits were collected from four species of tengkawangproducing shorea (i.e. S.macrophylla, S. gysbertsiana, S. stenoptera, S. pinanga) originated from 4 provenances and land races (Gunung BungaWest Kalimantan, Sungai Runtin-West Kalimantan, Bukit Baka-Central Kalimantan, and Haurbentes-West Java). Fruit samples from eleven combinations of species-provenances were extracted to assess fat yield and physical-chemical properties (i.e. moisture content, acid number and free fatty acid). Variation between species-provenances combination was high for all parameters tested, including the illipe nut's fat yield and moisture content. The highest fat yield with lowest moisture content was found in S. stenoptera from Haurbentes (West Java) and S. pinanga from Bukit Baka (Central Kalimantan). Both species-provenance combinations are recommended as genetic material to be developed in the program of ex-situ conservation as well as tree improvement program for the establishment of best seed sources in the same environment condition as the respected provenances.

Abstract

The magnitude  of the genotype-environment interaction (GEI) in seven six years  old seedling  seed orchards  of Eucalyptus pellita established  at three locations  in Indonesia  was examined  by analyzing height  and diameter.  The seed orchard  at each location  consists of 121 families  from three  provenances  of Papua  New  Guinea.  The pooled  sum of squares derived from analysis  of variance  of growth  of the three provenances  was used to estimate genetic  parameters.  These parameters  were  then used to calculate  genetic  gain as a result of both direct and indirect  selections.  The GEI across the three locations  was very  strong, while the results of pair-wise site analysis  varied between the pairs of locations.  The genetic correlations for pairs of locations  were moderately high between South Sumatra  and Riau;0.68 for dbh and 0.85 for height,  but were lower  between South Kalimantan and the other locations  (0.32 to 0.56). The gains resulting  from direct  selection  were  apparently greater than those resulting  from indirect  selection.  The genetic  gains achieved  in South Sumatra and Riau  would  decrease by 24% as a result  of transfer  to other  sites, while  transfer  from South Kalimantan to Sumatra  Island (and vice versa) would  reduce in the genetic  gain by 60%. Hence, the breeding  population in South Kalimantan should be developed separately from those in South Sumatra  and Riau

Abstract

ABSTRACT Combination of species-provenance test of tengkawang-producing Shorea species was established in 2011 in Gunung Dahu Research Station (West Java). Evaluation was conducted periodically every each six months for 18 months. The genetic materials used S. macrophylla, S. gybertsiana, S. stenoptera, S. pinanga derived   from 4 provenances (Gunung Bunga-West Kalimantan, Sungai Runtin-West Kalimantan, Bukit Baka-Central Kalimantan, and Haurbentes-West Java). The experiments were arranged in a Randomized Complete Blok Design (RCBD) with 11 plots, 4 replicated, 25 trees per plot (5 x 5 trees) and spacing of 5 x 5 meters. The traits observed were survival percentage and height at the age of 6, 12 and 18 months. The analysis showed that the survival percentage was not significantly different, while the growth height showed significant differences. Species of Shorea (S. macrophylla, S. stenoptera, and S. pinanga) from Haurbentes (West Java) land race had the best performance in growth until the age at 18 months.ABSTRAKKombinasi uji spesies-provenan jenis-jenis shorea penghasil tengkawang dibangun pada tahun 2011 di Stasiun Penelitian Meranti di Gunung Dahu, Bogor, Jawa Barat.

Abstract

The global energy crisis has raises demand for biofuel prices. It has driven the world to enhance environmentally-friendly renewable-energy (biofuel) production. Oil from the seeds of Calophyllum inophyllum (nyamplung) which can be harvested up to 50 years, is one of  such potential biofuel source. Methods for biofuel production from nyamplung seeds have been developed at an industrial scale by cooperative in Cilacap (Java) and Energy Self-Sufficient Villages (Desa Mandiri Energi) in Banyuwangi, Purworejo, Kebumen, Ujung Kulon (Java) and Selayar (South Sulawesi). However, there is only a limited-information available on biofuel potential, in term of  productivity and quality, from nyamplung populations. This paper reports the variations in biofuel potential among 12 populations in Indonesia (6 from Java, 6 outside Java). The oil was extracted using a combination of  vertical hot press (VHP) and screw press expeller (SPE) methods, followed by degumming to make refined oil, and esterification-transesterification to turn it into biodiesel. The result show great variation of  biofuel content among the population. Oil production percentage varies from 37-48.5% (VHP) and 50-58% (SPE) crude oil, 36-48% (VHP) and 40-53% (SPE) refined oil, and 1733% (SPE) for biodiesel. Seed resin content is responsible for most of the variation after degumming. DNA analysis shows genetic variation among populations ranges from intermediate within Java to high ouside Java and is intermediate within populations. Information about biofuel content and potential of  populations and genetic variation between and within population are important factors for establishment of  geneticallyimproved seed-sources for biofuel production from nyamplung.
