SIFAT FISIS PAPAN SEMEN DARI LIMBAH KULIT BATANG SAGU

This research objectives were to investigate possibility of using the waste of sago cortex (Ela sagu/Wa’a) in the manufacture of cement board and to determine the physical properties of cement board based on the comparison in proportion of materials (cement, sago, water)  and catalyst calcium chloride (CaCl2). Method were applied used completely randomesed design with tree replications in 3x3x3, with total 27 samples of cement board. The results shown that the waste of sago cortex ca be applied as raw materials to manufacture of cement board and fulfill the standard of particle board (JIS A 5908, 2003). The board have dencity which is almost equal to the target of dencity, lower value in water content, water absorption and thichness swelling so that have good performance in quality and stability dimensions. The sago cortex in side of base and the catalyst CaCl2 in 6% gave high performance for all physical properties of cement board

ANALISIS KANDUNGAN BIOMASSA DAN KARBON TERSIMPAN (Carbon Stock) PADA PSP (Plot Sampling Parmanent) HUTAN NEGERI SOYA KOTA AMBON.

Carbon stocks while amount of carbon stored on vegetation, other biomass and soil. Effort to reduce greenhouse gas concentrations at atmosphere (emissions) ito reduce CO2 into air. Amount of CO2 on air must be controlled by increasing of CO2 by plants as much as possible and reducing release of emissions as low as possible. Carbon stored reserves should be measured as attempt to carbon stocks in forest to decrease carbon emissions and adverse effects. Research do in September 2015 at parmanent sampling plot on 2012 at Soya included Mount Sirimau . Method of biomass and carbon stocks on Measurement and Calculation of Carbon Stock overall primary forests and secondary forests consist of 409. Total biomass content for For strata of primary forest biomass is 510 with 3590 tons / ha - 786.6950 tons / ha with average content of biomass at 640.4733 tons/ ha. .At secondary forest is 210.1608 tons / ha to 436.6976 tons / ha with 289.4509 tons / ha. Carbon-stored at primary forest is 239.9190 tons / ha to 369.0228 tons / ha with 301.1112 tons / ha. On secondary forest amount of carbon stored is 88.9805 tons / ha to 139.7868 tons / ha and 110.1785 tons / ha

PENGARUH PRODUKSI KAYU BULAT DAN JUMLAH IPHHK TERHADAP PRODUKSI KAYU GERGAJIAN DI PROVINSI MALUKU

Efforts to increase the utilization of forest products are realized in the form of forest product processing industries which are referred to as primary forest product industries. The total forest area in Maluku Province is 3,919,701 Ha. The potential of natural forest production has decreased significantly. This condition certainly affects the amount of roundwood produced, in other words, the production of round wood has also decreased. On the other hand, the demand for wood in Maluku is very high indicated by the high capacity of existing industries. This condition does not support the sustainability of the timber industry. This research was carried out with the aim of 1) Knowing the production of timber forest products based on a case study conducted in Maluku Province. 2) analyze the effect of sawn timber production and the number of IPHHK on sawn timber production. The result of research show that the number of IPHHK in Maluku Province in 2017 is 80 units of industrial enterprises, the primary of which is active in the process of processing processed wood as much as 57 units. The results of linear regression analysis, it can be seen that because Fcount 7 Ftable, 0.723> 0.457, then H0 is rejected, meaning that there is a significant influence between the amount of round wood production, the number of IPHHK together for sawn timber production

Grouping farmer income based on the type of livelihood which ranges from <Rp. 1,000,000, - Rp. 4,500,000 per family per year. Factors affecting the marketing aspect are market access and transaction processes for the selling price of commodities to be marketed, while the real problems in marketing in the study locations; Hunitetu, Rambatu, Rumberu and Rumahtita villages were the high prices of NTFsP commodity and the quite expensive of tranportatiom cost due to the market access has a high cost

ANALISIS TINGKAT KERAGAMAN PENGUKURAN VOLUME KAYU BULAT OLEH TENAGA TEKNIS PENGELOLAAN HUTAN PRODUKSI LESTARI (GANIS-PHPL) PADA APLIKASI SI-PUHH ONLINE

Therefore this study aims to analyze the level of diversity in the measurement of volume of logs in the field between researchers and Technical Personnel for Sustainable Production Forest Management (GANIS-PHPL) inputted in the SI-PUHH Online application. The method used is a quantitative method by developing models mathematical  (calculations), which are related to the measurement of logs. The results showed that the Technical Personnel for Sustainable Production Forest Management (GANIS-PHPL) owned by PT. Gema Hutani Lestari is not careful in carrying out its duties and authorities in measuring the correctness of the volume of logs, because there has been an excess volume tolerance of 5.97% of the set tolerance limit of 5%, giving rise to an element of state losses. Thus the performance and role of GANIS-PHPL is deemed necessary for guidance and control related to its duties and authority in terms of measuring and testing the volume of logs, so that the calculation of non-tax state revenue (PNBP) reaches the desired target
