Abstract

Forest is a natural resource which has an usefull existency to life. Development on plantation of industrial forest (HTI) needs to choose a kind of suitable plant which Eucalyptus pellita is the one that can be easily adapted. Stumps of Eucalyptus pellita from residual logging in the head office of University of Riau area produces coppices which can be a source of vegetative multiplication of plant. The aim of this research is to perceive a potential of the third generation of coppices which are able to grow in one stump of Eucalyptus pellita residual logging and to perceive the growth of the third generation of coppices on the stump of residual logging. This research exercises using an observation method. This specimen taken exercises a purpossive sampling method. The result of this observation indicates that coppices which grow on the stump of  Eucalyptus pellita residual logging have a potential in avarage amount of 9 coppices in each stump so that can be produced aprroximately 14.400 coppices/ha in a grow distance 2.5m x 2.5 m. This third generation has an average amount of 60 pieces of leaves in each stump and 10,5 cm high average accretion in 8 day measurement. Keywords:Eucalyptus pellita, Coppice, Growth.

Abstract

Acacia mangium is a comodity of plantation industry that has been developed. To get a good quality of Acacia mangium must use proper cultivation techniques. Mycorrhizae and Trichoderma spp. can improve seedling growth and suppresses pathogenic soil, but need to know the potential time to apply. This research aim to know the potential application of mycorrhizal time and Trichoderma spp. to increase seedling growth. This research used a completely randomized design (CRD), which consists of 4 treatments, 5 replications and each replication consisted of 10 seedlings. The treatments used were T1 = Trichoderma spp. the S-3 and mycorrhiza on S-1, T2 = Trichoderma spp. the S-1 and S-3 mycorrhiza on, T3 = Trichoderma spp. and mycorrhiza on the S-3, T4 = Trichoderma spp. and mycorrhiza on the S-1, where S = the seedlings were transferred to polybags. Responses were measured to observe the effect of the lived seedlings, height of seedling, diameter of seedlings, plant dry weight and the ratio of the crown / root. The results of this research shows that the application of Trichoderma spp. in three days before weaning and mycorrhiza in one day before weaning tend to show better results in the growth of Acacia mangium seedlings. Keywords: Acacia mangium, Mycorrhizae, Trichoderma spp., potential time.

Abstract

Bagasse is a waste which is usually dumped in open dumping without any further processing, so it will cause an enviromental disturbance. It is important to apply a technology to overcome the waste by using the recycle of solid waste into a use value of compost product. Top soil has been hard to find, because it is used continously in long time or has been eroded which cause the decreasing of avalaiblity. Alternative to avoid the decreasing of soil media quality, so the use of compost is predicted to increase the supply of soil nutrient. The purpose of this research is to determine the effect  of composting formulated bagasse for Acacia crassicarpa seedlings in top soil medium and to determine the best dose for seedling growth Acacia crassicarpa. This research uses a completely randomize design method which consist of 5 treatments, 4 replications, and 5 units of the plant as a research unit. P0 = without composting  formulated bagasse ; P1 = 25 g/polybag ; P2= 50 g/polybag ; P3 = 75 g/polybag ; p4 = 100 g/polybag. The result of this research indicates that  the composting formulated bagasse with 100 g/polybag dose is the best treatment in the parameter observations, the high increasing (36.45 cm), the diameter increasing (0.37 mm), the seedling dry weight (11.93 g), and the ratio of the root crown (6.40) for seedling Acacia crassicarpa in top soil medium. Keyword: : Compost bagasse, Trichoderma spp, Acacia crassicarpa.

Abstract

The mangrove forest is one of the unique and distinctive tropical forest ecosystems because it is a meeting between land and ocean ecosystems. Area of mangrove ecosystems in Bengkalis districtis in Teluk Pambang Village. Reduced width of mangrove forest located in Teluk Pambang Village, Bantan Subdistrict, Bengkalis districtis caused by changes in land use and land functions through a variety of activities of mangrove land conversion. Steps to anticipate the decline in value of mangrove forest ecosystems is by developing ecotourism activities. This study aims to determine the feasibility of the mangrove ecosystem in the Teluk Pambang village, as the object of ecotourism and determine public perceptions of the mangrove ecotourism in Teluk Pambang Village. The method used in analyzing the feasibility of the mangrove ecosystem as an object of ecotourism is based on the analysis of suitability for Yulianda (2007) tour mangrove ecosystems with the results obtained in the natural potential of the field then tabulated. Then, to determine the index of feasibility can be use dequation: IKW =  [Ni/Nmaks] x 100%, for the public perception of ecotourism analyzed descriptively qualitative. The results of this study indicated that the mangrove forest ecosystems in the Teluk Pambang Village included in the category of very decent (SI) for the mangrove ecotourism development. At Station I a value of IKW was 81.57%, Station II the value IKW 94.73%, while the Station III the value IKW 90.78%. The public perception of the ecotourism of mangrove forest in Teluk Pambang village was quite good, so it becomes a the main attraction to be developed as ecotourism and the community a greed that this location is used as a ecotourism of mangrove.

Abstract

The mangrove forest is plants that live in the mouth of the river and were able to survive in the tide. The area has a mangrove ecosystem in Bengkalis is Teluk Pambang Village and need to be developed into the ecotourism area. Ecotourism development goal is to protect the existing potentials in the mangrove forests and became one of the alternative sources in raising funds for conservation activities. This research purpose to identify the ecotourism potential of mangrove forest in Teluk Pambang Village, Bantan District Bengkalis Regency, to knowing the efforts and forms of conservation for the development of ecotourism and  to knowing the correlation of ecotourism potential as a supporting mangrove forest conservation. The method that used in analyzing the potential of ecotourism is based on the analysis of mangrove vegetation that expressed in the formula English et al. (1997) to obtain density and the importance of community structure of mangrove conservation, efforts and  forms was processed using a Likert Scale and the relation of potential ecotourism as a supporting mangrove forest data was processed by descriptive. The results of this research indicate that the ecotourism potential of mangrove forest in the Teluk Pambang Village, consists of very density  mangrove forest. Station I had a density of 2,967 ind/ha, station II has a density of 5,778 ind/ha and Station III has a density of 4,688 ind/ha, vegetation and wildlife are varieties and landscape of ecotourism still nature. Efforts and forms of conservation were managed by the Manage Group of Mangrove (KPM) Belukap, habits and knowledges of local communities (local wisdom) in Teluk Pambang Village and participation of respondents to the conservation efforts. The correlation of ecotourism potential to support conservation of mangrove forests are a visitor, education and research. Keywords: Potential, Mangrove Ecosystem, Ecotourism, Conservation
