Genetic diversity and relationship of four Acacia species, Acacia aulacocarpa, A. Cunn. ex Benth., A. auriculiformis Cunn. ex Benth., A. crassicarpa Cunn. ex Benth. and A. mangium Willd. were investigated using DNA molecular markers. Using RAPD analysis, a total of 20 arbitrar y primers successfully gave 127 polymorphic fragments. These RAPD data were used to estimate genetic distance and construct dendrograms using the unweighted pair-group with the arithmetic mean average (UPGMA) method. The four species were divided into two major clusters. A. auriculiformis and A. mangium were in one clust…
A study on demography,  growth  and survival of seedlings and saplings was conducted  in the Hutan Kintap  concenssion,  South Kalimantan,  Indonesia. The aim of  the study  was to monitor  pattern  of growth of seedlings and saplings among different types of logged -  over forest, including the newly  logged  -  forest, older  logged  -  over forests  (treated and untreated),  and un-logged-forest   patches.  The study began in 1991, and nineteen  of  0.25  ha plots  were set up i…
Various experimental testing procedures were undertaken in Indonesia to determine the effectiveness of a patented superficial (envelope) treatment using bifenthrin to protect radiata pine framing material from damage by two species of subterranean termites (Macrotermes gilvus and Coptotermes curvignathus) and one species of drywood termite (Cryptotermes cynocephalus). Lengths of framing material (Pinus radiata sapwood) were commercially treated to the targeted retention of 0.02% m/m of bifenthrin in the outer 2 mm depth penetration zone of the material. The treated and untreated materials were…
The fiber-plastic composites were made from the compounding of plastic (polypropylene) and sisal (Agave sisalana)fiber with or without addition of coupling agent (Maleic anhydride grafted polypropylene). The tensile strength (Modulus of Elasticity-MOE, Modulus of Rupture-MOR) of the composites were evaluated in the three different conditions, i.e. air dry condition (control), 24 - hour immersion in cold water and 2-hour immersion in boilingwater. The results showed that the addition of coupling agent enhanced the properties of the composites.  These properties di…
Aren (Arenga pinnata Merr.) is a multipurpose tree that can be utilized for palm sugar, alcoholic drinks, beverages and construction wood. The use of aren sawdust has not been studied intensively. This study examines the utilization of aren sawdust as cultivation media for edible mushrooms. Aren sawdust was mixed with rice bran, CaCO3, gypsum, fertilizers and distilled water before sterilization in 30 minutes pressurized autoclave at 1210C and 1.5atm. The mixed media was inoculated with pure cultures containing four mushrooms species (Pleurotus flabellatus, P. ostreatus, P. sajor-caju …
Provenance trial is a planting test aimed at ï¬ nding the best provenance for establishing forest plantations. Such best provenance depends on the type of ï¬ nal harvest or yield expected. The objective of this research was to identify A. mangium provenances that were suitable for forest plantation producing solid woods for construction and furniture. A total of 225 samples of 15 provenances from Papua New Guinea and Australia were planted in three blocks in Parungpanjang, Bogor, West Java. The measured parameters included tree height, clear bole height, stem diameter, tree volume,…
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…
This study describes the establishment of a compatible volume estimation model for Acacia mangium Willd on the basis of 279 felled sample trees collected from the A. mangium plantation stands in South Sumatra, Indonesia. The model comprises of a total volume model and a stem taper model, which is compatible in the sense of the total volume obtained by integration of the taper model being equal to that computed by the total volume model. Several well-known total volume functions were evaluated including constant form factor, combined variable, generalized combine variable, l…
This paper examines the issue of qath'i and zhanni in the realm of Islamic legal thought with regard to source of truth (wurud) and an indication of the law (dalalah). Terms qath'i and zhanni often associated with the position of the Qur'an and Sunnah judging from the aspect of al-tsubut or al-wurud (truth source/ constancy) and al- dalalah (meaning the content/ legal indications). This is done in an attempt to formulate and define the 'region' of Islam which can not be carried ijtihad. As the product ijtihadi, qath'i and zhanni only bore deviation among jurists in the level of assessment of w…
Berbagai peraturan sudah menyertai pengelolaan zakat di Indonesia, mulai zaman kolonial Belanda-pun sampai lahirnya beberapa tahun yang lalu secara yurudis yang namanya UU No. 38/1999. Memang panjang rentang sejarahnya, problematikanya banyak menyita waktu, tenaga dan fikiran serta perdebatan,tidak seperti eksis dan urgensinya sebagaimana lahirnya UU lainnya dan perealisasiannya, seperti UU pajak misalnya. Tetapi bagaimana-pun, tetap harus diakui bahwa upaya-upaya mengeksiskan sekaligus mengefektifkan pengelolaan zakat di negeri ini, merupakan kewajiban syariah, maka adalah suatu tanggung jawa…
The development of Islamic law in the modern world shows that Islamic law of inheritance (faraid) has become the most persistent part to the influences of modernity. The sacredness of faraid and its detailed Quranic regulation are among the reasons behind this situation. The development of Muslim family system from extended to become nuclear family system, however, has forced Muslim countires to reform their regulation of law. One of important fruits of the reform is strengthening the right of spouse and the descendant of muwarith, as the member of nuclear family. Husband or wife has a right t…
