Kerumutan Protected Forest is a conservation forest area in Riau Province which has the characteristics of peat swamp forest. This area has a disturbance of forest areas, illegal logging and forest fires that affect changes in forest cover. To determine the land cover changes in Kerumutan Protected Forest, monitoring was conducted to see land cover changes in the area. The purpose of this research was determined the land cover changes condition in Kerumutan Protected Forest area through interpretation of landsat imageris during 1996, 2008, 2013, and 2017. This research was carried out using the overlay process, test of accuracy and classification of reports between two classes of land cover in different years so that changes could determined. Based on results from landsat imageris analysis during 1996, 2008, 2013, and 2017, the land cover area of Kerumutan Protected Forest has changed, during 1996-2018 the primary land cover of wetland forest decreased to 14164,56 ha, secondary wetland forest increased to 13392,81 ha, swamps land increased to 7,83 ha, shrubs land decreased to 251,55 ha, open ground land increased to 33,21 ha, water body decreased to299,7 ha. During 2008-2013 the primary wetland forest decreased to 5604,39 ha, secondary wetland forest decreased to 12378,06 ha, swamps land increased to 19016,64 ha, shrubs land increased to 482,67 ha, open ground land increased to 276,39 ha, body water increased to 318,8 ha. During 2013-2017 the primary wetland forest increased to 17527,23 ha, secondary wetland forest decreased to 16779,33 ha, swamps land decreased to 4298,49 ha, shrubs land increased to 81,36 ha, open ground land decreased to 880,83 ha, and the body water increased to 336,06 ha.

Negative impacts due to development that are not environmentally friendly in urban area need to be reduced through the provision of green open-space. One of the green open-space in urban high aesthetic value and which can be used as a means of recreation is the urban forest. Urban forest that has the composition or richness of floristic tropical forests as well as the relatively large densities associated with environmental conditions such as climate, soil and light. Comformity level in Kisaran City is currently in the range uncomfortable category (HI value = >26). The management of urban forest that still prioritize aesthetic functions rather than hydrological functions has a role in determining the sense of comfort for people around the city forest.

Pekanbaru is a developing city that is characterized by increasing population and increasing use of green land to become densely populated area. City park is a part of public green open space garden (RTH) that is formed from tree vegetation and lower vegetation that provide comfort. This research aims to determine the level of environmental comfort level based on temperature humidity index (THI) and public perception. The tree vegetation data was collected by census method and the measurements were applied on temperature and humidity. Community perception derived from an interview by using questionnaire. The result showed that tree vegetation affected the measurement of temperature ang humidity. Based on THI value, Kaca Mayang green open space garden and Tunjuk Ajar Integritas are classified as uncomfortable level with a value >26. The assessment of visitors’ perception on comfort aspect depend on the accessibility, seating facilities and toilet facilities in the Kaca Mayang green open space garden. In addition the accessibility factor affects the comfort level in Tunjuk Ajar Integritas as well.

There are still many nibung stems on Bengkalis area especially in Temeran village. According to Nurlia, et al., (2013) in general use stem nibung done from generation to generation. The purpose of this study is Knowing anatomical properties nibung stem which covers the vascular bundles, parenchyma and nibung stem fibers. Knowing the physical properties of the nibung stem according to the height and depth of the stem including the water content, density, specific gravity and three-way shrinkage. Knowing the mechanical properties of the nibung stem which includes MOE (Modulus of Elasticity) and MOR (Modulus of Rupture). Properties The anatomy of the nibung stem shows that it is dominated by vascular bundles at the base then dominated by the parenchyma at the end. The color of the black nibung stem is striped on the skin and the color of the cream on the center of the skin and the basting. The physical properties of the nibung stem show that the skin edge of the nibung stem can be used as a lightweight construction because it has an average density value of 0.53 g. Cm-3, which is included in the strong class III. As for the center and pith section it is not recommended to be used as a construction, because the average density is 0.28 g.cm-3 in the middle and an average of 0.17 g.cm-3 in the pith section is included in the strong class V. The mechanical properties of the nibung stem were seen from the highest MOE and MOR values found on the edges of the skin, with an average MOE value of 584.78 kg.cm-2. Likewise for the MOR value the biggest nibung stem is found on the edge of the skin with a value of 432,527 kg.cm-2, and on the edges of the skin including the strong class II and the middle and the bile included in the strong class V.

The Replica of Istano Basa Pagaruyung is Minangkabau traditional house building in the form of a rumah gadang which is made with the guiding of the palace that ever existed before. Istano Basa Pagaruyung has been destroyed three times in the year 1837 due to the war, in 1996 and in 2007 due to burning. The existence and preservation of this traditional house must be maintained because it is a cultural symbol of Minangkabau society. This study aims to determine the type and criteria of wood used in making replica Istano Basa Pagaruyung based on public perception. This study uses snowball sampling method that has been implemented in October 2016 in Replica Istano Basa Pagaruyung. Criteria of wood used as raw material for reproduction of Istano Pagaruyung based on community perception that is hardwood, straight and have dark color. Under construction, the wood used should not be wet. Wood cutting system that is wood can not be felled in a flowering state, because at the time the wood has a delicious smell so favored by insects. Types of wood used are Toona sureni, Shorea leprosula Miq., Anisoptera costata Korth and Ptetospermum spp.
