Abstract

Effect of Gibberellins (GA4) on Germination Time and Height of Cendana (Santalum album Linn.) The hemiparasite Santalum album Linn. (cendana) grows very slow, in nature the rare and difficult seeds need stimulation to germinate. Gibberellins (including GA4) are growth regulators, usually used to increase growth as well as to break seed dormancy. The objectives of this research were to investigate the influence of gibberellins on germination percentage and height of cendana growth. Experiment was laid out in a Completely Randomized Design with 3 replicates of 300 seeds for germination percentage and 3 replicates of 10 seeds for seedling growth. Gibberellin was applied as treatment with 100, 300, and 500 ppm. The seed germination was recorded until 9 weeks, and height of plants measured until 8 months at the greenhouse. The results showed that the addition of gibberellins at all treatment increased the percentage of germination and caused the seeds germinated four weeks earlier than the control. In the first 4 months, 500 ppm gibberellins gave the highest acceleration of germination, afterward all treatments have relatively the same influences. Gibberellins gave positive effect on height of cendana growth. After 7 months, the growth decreased although all gibberellin treatments gave higher growth than the control.

Abstract

In Uganda, a large diversity of community initiated forest management systems have evolved recently in response to severe degradation of forests and grazing land and biomass shortages. Forestry professional, forest user group and farmers were organized in June 2004 to develop commonly agreed indicators of the performance of Community Forestry Program in Uganda. Indicators, such as access to fuel wood, incidence of forest fire and amount of community funds raised through the sale offorest products are commonly agreed at local level. Women participation in forestry related meetings and taste of drinking water in the watershed area are also important. Equitable benefit sharing by the community forest users serves as an indicator of better access to forest products. Socio-economic changes such as women participation in forest related decision-making, income generated from community forests, and equity of benefits from community forests also, reflect the program success.

Abstract

Growth Evaluation of Several Provenances of Sungkai (Peronema Canescens Jack) Seedlings in South KalimantanSungkai (Peronema canescens Jack) is among the species recommended for industrial forest plantation (IFP) by the Ministry of Forestry. Despite this fact, very little is known about the extent of genetic variation in wild populations and few attempts, if any, have been made at genetic improvement. Sungkai cuttings are collected wherever available, rather than companies seeking high-quality stockplants. No effort  has been made to increase the quality of cuttings by collecting them from different geographical origins (provenance test). Cuttings from five provenances in South Kalimantan were tested at nursery stage in order to indent6 the best provenance. The result showed that all provenance had a 100% survival rate. Kandangan provenance was the fastest in finishing shoots formation. There is no significant difference in term of shoot length however, in average, provenances from Tambarangan and Tanjung had longer shoots, i.e. 31 cm and 30.65 cm, respectively.

Abstract

Crown Model on Several Family of   9 years old  of Teak (Tectona grandis L.f) Progeny TrialCrown plays an important role in regulating the rate of tree growth through the photosynthesis process. Furthermore it can be used to measure stand density and to determine the availability of growing space. Because of the difficulty  and time consuming in direct crown measurement, the development of crown model is needed. The objectives of this study were to develop crown models of teak (Tectona grandis) of 9 years old from selected open pollinated families and to identifi) the variations of crown models among them.The study was conducted in an open pollinated progeny test located at the compartment 49a, RPH Sidowayah, BKPH Kedunggalar, KPH Ngawi. The experimental unit was family. Five families with the best average of stem diameter at breast height were selected as samples. Crown models were developed and variations of crown model were tested with analysis of variance.The crown model of teak can be divided into two sections. The upper crown representing the light crown section followed parabolic model while the under crown representing the shaded crown section followed linear model. No differences in crown model were found among families. The proposed models are:light crown section, paraboloid : Rl =1.91 * hl0.33shaded crown section, linear .. Rs = -0.75 + 0.57 hswhere Rl is light crown radius (m), hl is the height of light crown section (m), Rs is shaded crown radius (m) and hs is the height of shaded crown section (m)

Abstract

Important Values of Agroforestry, Community Forest, and Agricultural Land on Conservation of Bird Diversity in Paliyan, Gunungkidul, YogyakartaAgroforestry is recognized as a land use management that capable to integrate the need of local peoples and the concern of biodiversity conservation. However, some contradictory results of studies made the importance of agroforestry on conservation of biodiversity questionable. To understand the role of agro­forestry in biodiversity conservation, bird community assemblages of three land use types namely private forests, agroforestry and annual crops were compared. Single belt point count with a radius of 50 m was used to survey birds. In general species diversity in the study area was at a moderate level. Statistically, bird communities between sites did not differ significantly in term of their abundance, species composition, and diversity. It was because patch context plays more important role than patch content. However, it was found that in all community parameter agroforestry area has higher values than those of crops. Consistent with the previous studies, insectivorous birds were the most sensitive to land use changes. The conservation value of Paliyan area was relatively low, because most of species were abundant, and no species inhabit endangered status according to IUCN criteria. Implication of this research was that Paliyan area need a large-compact habitat to conserve high bird diversity.

Abstract

Phenyl Certification: Public Perception and Impacts of Certification of the Local Scale Forest Management (Study Case in Selopuro and Sumberejo Villages, Batuwarno Sub District, Wonogiri Regency, Central Java)In 2002, Indonesian Ecolabel Institution (LEI) established the so-called Sustainable Community Based Forest Management Certification system (PHBML). In 2004, with a PHBML certificate award, the community forest management units in Selopuro and Sumberejo villages, Batuwarno sub district, Wonogiri Regency, Central Java were anknowledged as the best institution in sustainable yield function, social function, and ecological function aspects. This research was aimed to find out the community's kind of perception, as well as that of KPS (Certification Farmer Community) officials and members in particular, to PHBML certification implementation. Also, the study was intended to discover the impact of PHBML certification upon the local scale forest management.The research findings indicated that the community's level of understanding to PHBML certification was poor when compared with that of KPS officials. This condition due to the official failure to share the knowledge they had receivedfrom NGO with the KPS members. With PHBML certification, the institutional management by forest farmers had been proven improved however, there have not been yet any significant improvement to farmer income, and to forest product marketing. In addition to this, what was meant by significance, did not fully answer the farmer expectation of better sustainable forest principle realization.
