Abstract

Tumih wood (Combretocarpus rotundatus (Miq.) Danser) is classified as an unknown type of wood which is widely grown in peat swamp forests in Central Kalimantan. This study aims to analyze the physical properties and mechanical properties of wood in axial and radial directions so that they can be utilized properly. The results of the study resulted in fresh water content and dry air content of wood air, each of which was 71,58% and 19,33%, kiln dry weight 0,72, tangential shrinkage 9,68%, radial shrinkage 5,02% and longitudinal shrinkage 0,19%. Testing of mechanical properties resulted in a flexural firmness of 618,33 kg/cm2, compressive strength parallel to the fiber 333,27kg/cm2, shear constancy 92,02 kg/cm2, hardness 355,60 kg/cm2, and stiffness at 19,50kg/cm2. Based on the Indonesian Wood Construction Regulations Standard (PKKI) NI 5-1961 tumih wood is included as a strong class III of Indonesian wood, so it is quite well used for home building raw materials, beams, floor and wall boards, door/window frames, and furniture.

Abstract

The objectives of the research are to: (1) find out the effectiveness of the implementation of education autonomy policy from regency / city to province; (2) to know the effectiveness of the realization of education budget; (3) to know the effectiveness of quality improvement of education quality; (4) to know politicization; And (5) finding new strategies for implementing education autonomy policies. The study used the Tyler model evaluation study. Level of effectiveness using percentages. Qualitative data were analyzed with McMilland model. The validity of qualitative data uses credibility, dependability, transferability, and confirmability.The study concluded: (1) the implementation of education policy autonomy is about 50% (quite effective), qualitatively ineffective; (2) the realization of the education budget is 25% (not effective) and also qualitatively ineffective; (3) teacher quality improvement 65.30% (effective), qualitatively ineffective; (4) teacher politicization hampers the professionalism and career development of teachers, shifts the politicization of teachers from districts / municipalities to the politics of what, when, and how to get something, no true friend of true interest, art of possibility, way; (5) the new strategy for streamlining the implementation of education autonomy policy is 8K in bebaya
