Abstract

The Giam Siak Kecil-Bukit Batu Biosphere Reserve was managed by zonation as a approach for multibenefitof management goals. This Bioshere Reserve has a fairly high carbon stock stored in its naturalpeat swamp forest ecosystems. Nevertheless, the condition of the peat swamp forest in the BiosphereGiam Siak Kecil-Bukit Batu currently has been destructed, especially in the buffer and transition zones.The threats of protected areas are not only coming from forest fire factors, but also from encroachmentand illegal logging. Therefore, it requires a recovery effort. This research aims to determine the survivalrate and to estimate the above ground biomass accumulation of the main tree species of peat swamp forestthat used to restore the burnt peat. The estimated total biomass accumulation on the surface was measured using allometric equations. Result of this research proved that Jelutung tree (Dyera polyphylla) has thebest survival rate among the trees (98%), while banana tree (Mezzettia parviflora) has lower survival rate( 35%). The highest total biomass accumulation was found in Jelutung (Dyera polyphylla) (499.015kg/ha/year, while the lowest total biomass accumulation was found in Meranti batu (Shorea uliginosa)(88.867 kg/ha/year). A total of nine pioneer species were identified i.e. Tenggek burung (Euodia sp),kayu ara (Ficus sp), mahang (Macaranga triloba), karet (Havea brasiliensis), sendayan (Scleriasumatrensis), alang-alang (Imperata cylindrica), senduduk (Melastoma malabathricum), paku-pakuan(Neprolepis hirsutula) and rumput teki (Cyperus rotundus). The total biomass accumulation of earlysuccession in all types of vegetation pioneer is 338,91 kg/ha.Key words: Above Ground Biomass Accumulation, restoration, vegetasion succession, burned peatland,Survival Rate.

Abstract

In its history, politically, liberalism of Islam accepts deep momentum during Sultanate-Autonomy in Turkey, where Islamic countries, especially Turkey and Egypt, which had got in touch with western world, had big influences toward Islamic societies’ attitude. This influence made the Turkish and the Egyptian understands rigid. Islamic scholars of law seem confused to see new thing in Islamic societies. A case will directly be instructed “illegal” or haram if the case itself cannot be found in the school of Hanafi’s classical books. Then, this paper is intended to contribute some points of view of this school by means of answering some main questions about the truth of Islamic liberal considered as a secular movement under the guise of Moslem, the truth of the discourse of Islamic liberalism presents the past for the sake of modernization and the truth of Islamic liberalism that is irrelevant to the Indonesian culture.

Abstract

CV. Citra Jepara is a company that processes wood into furniture?s product with hectic activity production so it causes indoor air pollution i.e wood dust. Wood dust causes bad impact on health such as respiratory disorder, skin irritation even lung cancer. The purpose of this research was to assess the environmental health risks of wood dust exposure on sanding unit among workers. Sanding unit was chosen because it was the highest dust concentration level in production unit.  Research design was using cross sectional with analysis of environmental health risk approach (EHRA). Subject?s population were 30 sanding unit workers and object?s population was the air in sanding unit workplace. While the subject?s samples were 30 sanding unit workers (using total sampling method) the object?s sample was the air in sanding unit workplace with 2 sampling points. Data was analyzed using EHRA stages which were danger identification, respond dose analysis, exposure analysis, and risk characteristics. Result of this research showed that the average of measurement result of total dust concentration in sanding unit was 21,5 mg/m3. Mean weight of worker was 56 kg, mean exposure period was 11 hours,  mean exposure frequency was 298 days and mean exposure duration was 6 years. It can be concluded that total dust concentration in sanding unit was above the specified quality standard and mean real time exposure of non carsinogenic and carsinogenic effect was classified as safe. However, life time exposure of non carsinogenic and carsinogenic effect was above 1 and classified as risky. Estimated calculation of real time exposure risk showed that workers would be at risk of non cancer in 30 years ahead. Workers would be at risk of cancer in 25 years ahead.
