Abstract

Mangrove condition deteriorating lead to the quality and quantity of mangrove seedlings wane. To improve and get better mangrove seedlings, then the required rehabilitation of mangroves. One of the efforts is the use of various types of fungi that can enhance the growth of mangroves for the better. This research can provide information on the types of fungi are able to increase growth of seedling R mucronata. This study was conducted from June 2014 until January 2015 using a completely randomized design (CRD) with treatment application types of fungi and five replications. There are three types of fungi namely A. flavus applied,  A.terreus T. harzianum. Application of Trichoderma harzianum gave the best results on seedling growth parameters R. mucronata, with an average height of 15.48 cm, a diameter of 0.47 cm, 1375.43 cm2 leaf area, and total dry weight of 119.50 g higher than the average of control and another fungi.Keywords: Rhizophora mucronata,  Fungi,  Mangrove, Rehabilitation.

Abstract

The benefit of A. marina nursery is to provide A. marina mangrove seed that has good quality. Mangrove vegetation A. marina can survive in site conditions that have accumulated metals with the help of fungi that neutralize the accumulation of metals. Each of result has correlation which strong to A. marina growth. This research can provide information on the types of fungi who has capability to improve growth of A.marina. this research was conducted from September 2014 until May 2015 using a completely randomized design (CRD) with treatment application types of fungi and five replications. There are three type of fungi namely A. flavus, A.tereus, and T.harzianum. Application of Trichoderma harzianum gave the best result on seedling growth parameters A. marina, with a diameter of 0,392 cm, an average height of 1,3 g, and a leaf area of 28,08 cm. A. terreus gave the best result on seedling growth parameters A. marina with an average height 20,22 cm and a diameter of 0,392 cm.Keyword: fungi,  Avicennia marina, mangrove, nursery.

Abstract

Condition of mangrove area has been decreasing due to the degradation and conversion of mangrove for other land use. Therefore, it is necessary for rehabilitation on mangrove land. This study aimed to test the ability of various types fungi on a field scale then to compare the ability of fungi to increase the growth of mangroves and to establish a type of fungi that have a greater ability to promote the growth of mangroves.  B. gymnorrhiza seed was used with 4 treatments. The results showed a response Bruguiera gymnorrhiza seedlings treated with the fungi Aspergillus flavus applications, Aspergillus terreus, and Trichoderma harzianum effect on seedling growth. T. harzianum showed the best results compared to other fungi on all parameters of observation with an average height of 10,45 cm, an average diameter of 0,56 cm, average leaf area rat 104,87 cm2, and the total dry weight of 2, 65 g. All parameters observed fungal applications only affected on height growth and total dry weight significantly on B. gymnorrhiza seedlings.Keywords: Bruguiera gymnorrhiza, mangrove, rehabilitation, Trichoderma harzianum

Abstract

Mangrove forest is one of coastal ecosystems that have high productivity. Recently, mangrove damaged either directly or indirectly. Direct damage for example logging, timber harvesting, settlement construction and ponds manufacturing, ports and roads construction, and arrest biota in mangrove ecosystems. Furthermore, indrectly threat maybe caused by coastal dredging, disposal of waste and industrial waste in the sea and the coast, coastal and marine mining, and deforestation. As a result above-mentioned threat of degraded mangrove forests.   Therefore, it is needed for rehabilitation efforts. The research was conducted in September 2014 to January 2015 using a completely randomized design (CRD) with treatments of A. flavus, A. tereus and T. harzianum and with five replications. Results showed that different fungi treatment provided different growth response. The highest mean of height growth obtained from B. cylindrica  seedlings treated with A. tereus that was 7.29 cm. The largest diameter was obtained seed treated with T. harzianum by 0.42 cm. The highest value of dry weight obtained from seedlings treated with fungi A. tereus that was 1.74 g. The largest leaf area obtained from seedlings treated with fungus of T. harzianum, that was 402.23 cm2.Keywords: A. flavus, B. cylindrica , fungi, Mangrove, T. harzianum.

Abstract

Reforestation is an activity that involves planting or regeneration of trees and other plants in the State forest areas and in other areas in other areas based on land-use plan designated as forest. The purpose of this study was to determine the public perception of the difficulty of successful reforestation activities in the Region Captive Air of Lake Toba. The data is taken from primary and secondary data. Primary data is information collected by reforestation activities in the villages, secondary data collected in the study site general conditions existing at the village government agencies which sampling method was done by purposive sampling ie sampling deliberately chosen. The results showed a lack of socialization in the extension of government reforestation activities, uncontrolled forest fires, lack of maintenance of seed that has been planted, the type of plant is less suitable.Keywords: Reforestation, Catchment area, purposive sampling, education, fire.

Abstract

Forests and land in the catchment area of TobaLake  showed a decrease for  quality and quantity of the land. This study aims to identify the breadfruit seeds (Artocarpus communis Forst) for the growth responseagainst granting additional material to the growing media in the form of water retaining material. This research was conductedinthe Catchment Area of Toba Lake, Simalungun district.The result showed that the interaction of charcoal dose treatment did not significantly affect the mean height increament, diameter, number of leaves, water content, leaf area, and spacious canopy.Keywords: Breadfruit (Artocarpus communis Forst), charcoal

Abstract

This research aims to  know the  best dose  of  fertilizer  (chicken  manure) in the growth of breadfruit as land rehabilitation efforts) in the catchment area of Lake Toba Haranggaol horison district. The method used in this study is a randomized block design (RBD) non factorial with 11 treatments and 4 replications. The parameters used in this study are as height, diameter, number of leaves, leaf area, crown area and leaf water content. The  results  showed the  addition of manure  can  provide  good  growth response to breadfruit plant. In various parameters showed dose of chicken manure 700 and 800 gr give a better effect than the other doses. Analysis of   variance ANOVA showed dose of  chicken manure does not provide significant effect on the growth of breadfruit plant.Key word: critical land, breadfruit, dose of chicken manure, Lake Toba Catchment Area

Abstract

Cylindrocladium sp. is one of the diseases caused on leaf. Eucalyptus sp. is a plant that is used in the pulp industry. The objective of this study  to characterize the symptoms of foliar diseases and measure the desiases severity and diseases incidence on clone IND 65, IND 68 and IND 69. The infection of Cylindrocladium sp. was implemented with spraying method. Cylindrocladium sp., showed the symptoms was  redness brown spots and patches of grayish. Based on the diseases severity criteria three clones classifield as resistant clones. Based on the diseases incidence criteria of IND 65, IND 68  were classified as resistant and  IND 69 quite a bit resistant.Key words: Cylindrocladium sp., Eucalyptus sp.,  Infection test.
