Kajian Pengelolaan Hutan Mangrove di Desa Pulau Pahawang Kecamatan Marga Punduh Kabupaten Pesawaran

Sustainable of mangrove forest management is a proper activity in land and forest product utilization at the coast area. This activity is decent step to relieve mangrove ecosystem demage and preserve it. The circumstances and the factors influenced mangrove forest still needs to be known for the continued in management. The purposes of this study were to determine how the mangrove forest management and development strategy of mangrove forest management. This study was conducted by interviewing the relevant agencies and key informans in the village of Pahawang island from January-April 2015. Datas processing was analyzed by SWOT and descriptive. Result showed that mangrove forest management in good enough with aggressive score (1,22 ; 0,73), which means this strategy gives priority to immediate action by exploiting chances and maintaining strength (growth oriented strategy). Development strategy in the management have to support each other between relevant agencies, the managers, and society. Besides, tracking mangrove development has to be conducted considering the good forest potentials, with the existence of village regulations, and good response from society towards this plan. The strategy should be done by involving Mangrove Protected Area Management Agency and community to optimalize the development. Sustainability of mangrove forest management, should be accompanied with the advanced knowladge of management. Other priority development is by giving counseling, expert-accompanied training, and efficient technological development

Sifat Fisis Dan Mekanis Oriented Strand Board Hibrida Bambu Pada Berbagai Shelling Ratio (Physical and Mechanical Properties of Hybrid Bamboo Oriented Strand Board at Various Shelling Ratios)

Hybrid Bamboo Oriented Strand Boards (OSB) were produced to improve bamboo OSB's physical and mechanical properties. Shelling ratio adjustment of the strand type combination could determine the optimal physical and mechanical properties of hybrid bamboo oriented strand boards (OSB). The purpose of this study was to evaluate the physical and mechanical properties of hybrid betung and andong bamboos OSB at various shelling ratios. Steam modified strands of betung and andong bamboo were used as an outer layer and core layer, respectively. Hybrid bamboo OSBs were prepared with 0.7 g cm-3 target density and 8% phenol-formaldehyde resin content. Three layers of OSB were made with outer: core shelling ratios of 30:70, 40:60, 50:50, and 60:40. The physical and mechanical properties of the OSB were tested referring to the JIS A 5908-2003 standard. The targeted board density was achieved and the physical properties of all hybrid bamboo OSB have met the requirement of CSA O437.0 (Grade O-1) standard criteria. The parallel modulus of elasticity (MOE) and modulus of rupture (MOR) increased with increasing outer layer ratio. However, the perpendicular MOE and MOR decreased with increasing outer layer ratio. The internal bonding (IB) of the OSB with a shelling ratio of 30:70 and 40:60 met with the requirement of the CSA O437.0 (Grade O-1) standard
