Abstract

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.

Abstract

Bukit Suligi Protection Forest was a protected forest in Riau area which is a stretch of wet tropical forest. The forest land cover of this area continues to decline due to forest fires and forest area conversion. These problems will affected changes in the Bukit Suligi Protection Forest cover. Efforts to find out the change in cover of Bukit Suligi Protected Forest Area land was monitored to see changes in land cover in the area. The purpose of research was changes detection the Bukit Suligi Protection Forest cover in Kampar District through interpretation of Landsat imageries 1997, 2007 and 2017. Identify factors that cause changes in the cover of Bukit Suligi Protection Forest. This research analyzed land cover changes and interviews. Based on the results of interpretation of Landsat imageries in 1997, 2007 and 2017, land cover changes that occurred in the period 1997 - 2017 reached 4447.62 ha or 76.76% of the total area. If described in the period 1997 - 2007 land cover changes amounted to 2920.32 ha or 50.40% of the total area, these changes continue to increase until the period 2007 - 2017 land cover changes of 3627 ha or 62.60% of the total area. Factors that influence changes in the cover area of Bukit Suligi Protection Forest are natural factors and human factors. The human factor consists of population growth and government policies, namely the lack of supervision by the government in the forestry sector, specifically the management of the Bukit Suligi Protected Forest area

Abstract

Alstonia scholaris is one of the plant indigenous and able to grow rapidly. In the application of fertilizer should be can improve the yields a plant including Alstonia scholaris. Solutions offered as used fertilizer local, the use of waste as fertilizer need to be improved. One of effective way is to take advantage of waste rubber (leaves) be the fertilizer the form of liquid smoke. The purpose of this research is to determine the growth seedling Alstonia scholaris by administering liquid smoke of litter leaves rubber as fertilizer liquid. This study conducted by the method of the Complete Random Design (CRD) with 4 treatment 3 times repeat with each experiment consist of 10 plants so obtained 120 units plants. The results that the application of liquid smoke influential growth seedling Alstonia scholaris dose is best P2 (3 ml/L water), by showing the result of 100% percent of life seedling, growt of plant height is 16,98 cm and dry weight of plant is 29,97 g.

Abstract

Antochephalus cadamba is a local Indonesian plant that grows very fast and can thrive in tropical forests. Good quality Antochephalus cadamba seeds are needed to make sure the success of the planter and good results. Local Micro Organism (LMO) is a solution of the decay of organic materials derived from plant residues, animal feces, and humans, which contain more than one element. Local Micro Organisms are micro-organisms that are used as starters in making solid organic fertilizers and liquid fertilizers. The aim of the study was to find the effect of Local Micro Organism fertilizer on the growth of Antochephalus cadamba seedlings and the best dose of LMO fertilizer to trigger the growth of seedlings. This research was carried out with an experimental method using a non factorial Completely Randomized Design, LMO fertilizer consisting of five treatments with four replications, to get twenty experimental units. The results that the application of LMO fertilizer on the growth of Antochephalus cadamba dose is best 60 cc/plant, by showing the result of 100% percent of life seedling, growt of plant height is 15,03 cm and dry weight of plant is 35,11 g.

Abstract

Green line is one way to fulfill the existence of green open space in urban areas, it was covered by various types of plants from land cover crops to trees. The condition of trees in the green lane must be in good condition and healthy so it can comfort the road users. Considering the importance of trees in urban areas, the health of trees must be considered to prevent accidents which caused by trees along the road. The purpose of this research was to evaluate the health of trees on the green lane at Arifin Achmad street, Pekanbaru. This research was conducted by census method and scoring method that consisting of the health and quality of trees along Arifin Achmad street. The quality of trees in the green line at Arifin Achmad in Pekanbaru City were reviewed from stem health (75,59%) it means that the trees on the green lane were healthy. The quality of trees of threats to roads, sidewalks and drainage networks (81,66) classified into light category.

Abstract

Anthocephalus cadamba can be used as one of the alternative plantations because Anthocephalus cadamba is a fast-growing plant species. Disorders by disease attacks can reduce the quality and quantity of wood in the Anthocephalus cadamba stands. Diseases that attack a plant forest population can be very destructive and accompanied by symptoms and signs. Disease attacks will result imbalanced ecosystem if it is not properly considered. The purpose of this research was to determine the intensity of disease attacks on Anthocephalus cadamba stands. Research conducted on Anthocephalus cadamba stands that have an area of 2 ha with a plant distance of 3m x 4m using the survey method showed the intensity of disease attacks on Anthocephalus cadamba stands at Raya PasirPutih street was 24,75%. The most common criteria for the attack of Anthocephalus cadamba disease are mild attacks by 91,0%, then healthy by 5,5%, then moderate attacks by 2,5% and the least were severe attacks by 1,0% of 800 Anthocephalus cadamba stands.The disease that attacks the Anthocephalus cadamba stands were leaf spot, flour dew, soot dew and stem cancer.
