Abstract

Legume  Cover  Crop  establishment  is  vegetative  method for  erosion  control  in  the  slope  area.  Calopogonium mucunoides, Centrosema pubescens, and Pueraria javanica are the species  are uses as mixed  Legume Cover Crop for erosion control. The problem in cover crop planting on slope area is the seed easy wash away by the rain, so erosion control in the slope area can not be implemented properly. The Templok Method is a new method for planting Legume Cover Crop in the slope area. This method use TeraGlue as kohesif material, for straw or litter as planting media and cocofiber net. This research done at area with  ± 70° slope in Gunung Walat Forest Education, Sukabumi.           The result of this research indicate that Templok Method by using TeraGlue, straw and litter media also cocofiber net can give good effect of planting Legum Cover Crop in the slope area. Based on this first research, Templok Method can be use as alternative solution for planting Legum Cover Crop for erosion control in slope area.

Abstract

The need for teak wood processing in Indonesia is still high both for domestic demand and export wood demand. But the shortage of teak wood demand can give opportunities for people to cultivate teak on their privately land. The purpose of this research is to examine the main plant growth of teak (Tectona grandis Linn F.) in small scale private forest and compare it with teak’s growth from monoculture forest at Perum Perhutani KPH Sumedang in same ages. The main data of plant dimensional were taken with census method from teak plants in each of the selected land such as height, canopy diameter and canopy projection. In this research, soil parameter observed consist of physical and chemical content of soil  samples  from  each  selected  land  then  analyzed  in  laboratory.  Crown  closure  data  taken  by  using  a  spiracle     densiometer. The history of land management known by interview with farmers in each selected land. Those data were analyzed descriptively.            The results showed that the observed forest have 3 (three) different age classes of teak plantation. They are teak plant with  class  age  of  3  years,  6  years,  and  12  years  whom  the  growth  of  teak  are  different  in  those  parameter  such  as diameter, height, crown closure and basal area. Growth of teak plantation in the village of Babakan Asem is a plant with  the best teak growth among the other villages. Their growth maybe influenced by several factors, that is  the condition of the site or soil condition factors and cultivation activities. The result of crown closure show that the majority of sunlight blocked  by  the  crop  canopy  of  teak,  so  less  than  40%  of  sunlight  can  reach  the  soil  surface.  That  condition  maybe affected by size crop of teak and the distance between teak plantation it self. The result of soil analysis indicated that  physical and chemical soil content in Conggeang District are impact on teak growth which bulk density, water storage, KTK, pH, and other chemical substance are related to teak diameter’s  growth.             Growth  of  teak  plantation  between  small  scale  private forest  and  Perum  Perhutani  were  significantly different  in class  ages of  3 and 12 years  and didn’t  different  at  class ages of  6 years  in diameter.  The difference in  teak growth between  small  scale  private  forest  and  Perum  Perhutani  are  caused  by  a  factor  of  using  teak  seed  and  the  forest management.

Abstract

The Comparison of Carbon Stocks on Some Land Cover at Paser, East Kalimantan Based on Its Soil Physical and Soil ChemicalForest has a lot of direct and indirectly benefits for life. Direct benefits of forest are timber, non timber forest products and wildlife/fauna. While, indirect benefits of forest are the environment services as the hydrology regulator, aesthetic function, producer of oxygen and carbon absorber. Forest is the largest carbon absorber (sinks) and having an important part in the global carbon cycles, however forest can also produce a carbon emission (source). Forest ecosystem has ability to absorb and store different kinds of carbon even in the natural forest, mangrove, swamp, forest plantation and at the folk’s forest. The differences of carbon sinks are influenced by number and tree density, trees species, biotic factors which consist of radiation, humidity, temperature and soil fertility which affect the rate of photosynthesis. The land fertility was determined by soil physical, soil chemical, and soil biological. Therefore, this research aims to compare carbon stocks on some land cover based on its soil physical and soil chemical.The research was performed at some lands coverings of Paser, East Kalimantan in January to July 2011. Data was processed and analyzed in the Forest Influence Laboratory, Department of silviculture, Faculty of Forestry, Bogor Agriculture University and Land Laboratory, Land Research Hall. Measurement of biomass and carbon sinks were performed by using the diameter data of stand and height in each land covering. Analysis of soil physical temper (texture and soil bulk density) and soil chemical (pH, CEC, Ratio of C/N, P, K, Ca, and Mg) were performed to disturbed and undisturbed soils. The result of research  showed that mangrove forest had the greatest carbon sinks, that was 51.5031 tons/hectares. While, the lowest carbon sinks was on the palm oil plantation for 0.1046 tons/hectares. From soil analysis result was  known that swamp forest tended to be more fertile compared with other land coverings. Whereas, palm oil plantation and agroforestry is indicated the lower of land fertility. The raising of soil physical and soil chemical’s value increase the carbon stocks on each land cover, exception of bulk density that decrease the carbon stocks. The result analysis correlation showed in insignificant value, its indicated by the value of r2 less than 99%(0,99) or 95%(0,95). Need to research about estimation carbon stocks on the other land cover, and compare the carbon stocks based on the other land characteristics, as topography and climate.

Abstract

The potention of mangrove forests in Indonesia has been decreasing. Therefore, rehabilitation is necessary in order to maintain sustainability of forest ecosystems. One of the efforts is the replanting of mangrove forest. The success of planting depends on the availability of seed. Seeds can not be obtained any time if needed so that storage seed is necessary for seed viability can be maintained within a certain time period until the time of planting arrives. The problem has been arise because of   Rhizophora mucronata is a recalcitrant seed, which is at certain moisture content that relatively high, the propagule tend to be easy to germinate and if the moisture content is low, the propagule will be die or loss of their viability. This study aims to investigate the influence of storage media, storage room and time of storage on propagules viability of R. mucronata and to compare between  the germination from the rapid test (cutting test) and the germination from the direct test.This study used a factorial experiment with completely randomized design (CRD) factorial 5x2x2 with 3 replicates. The details of the factors are: factor A (time of storage) consists of A0 (0 weeks), A1 (1 week), A2 (2 weeks), A3 (3 weeks), and A4 (4 weeks); factor B (storage room) consists of B1 (AC room) and B2 (living room); and factor C (storage media) consists of C1 (sawdust) and C2 (coconut husk).The data collected is the result of cutting test from propagule, the percentage of rooted propagule (PB), moisture content (MC), germination (DB), germination value (NP), the growth rates (KT), shoot and root ratio (NPA). Based on these results, the influence of interaction between storage time, storage room and storage media caused significant differences on germination propagule R. mucronata. The influence of interaction between storage time and storage room caused significant differences to the percent of rooted from propagule R. mucronata. The influence of storage time and storage media caused significant differences in seedling roots to shoot ratio of R. mucronata. In this study, coconut husk media storage that is placed in the air conditioner room capable to maintaining the viability of propagule R. mucronata until the time of storage for 4 weeks. The result of estimation methods viability propagule R. mucronata with cutting test is relatively similar with the directly propagul germination test results.

Abstract

Utilization of Organic Fertilizer to Productivity Mulberry (Morus alba) Leaf’s Quality as Silkworm (Bombyx mori) FeedOne of effort, to obtain maximum cocoon production by feeding silkworms with mulberry leaves are sufficiant. Fertilizing by using organic fertilizer was one of effort to improve mulberry productivity. Organic fertilizer used in this research was animal manure, liquid organic fertilizer and compost. Measurement of parameters of mulberry productivity were leaf total, leaf weight, leaf area, plant height, branch length, and branch total; while observed parameters of silkworm cocoon quality were mortality percentage, cocoon weight, cocoon skin weight, cocoon skin percentage, and cocoon quality class.ANOVA test result shows that application fertilizers has an insignificant effect to leaf total, leaf weight, plant height, and branch length. Treatment by using a liquid organic fertilizer had the highest values for all parameters measured. Adversely, fertilizing has a significant effect to leaf area, branch total, cocoon weight, cocoon skin weight and cocoon skin percentage. Highest mortality percentage was resulted from control treatment that was amounted 13.75%; while lowest mortality percentage was resulted from compost fertilizer treatment that amounted 4.75%. Highest cocoon weight, cocoon skin weight and cocoon skin percentage was resulted from animal manure treatment. Best cocoon quality was B class for control, animal manure and liquid organic fertilizer, while for treatment using compost fertilizer has a C class cocoon quality. In an outline granting manure, liquid organic fertilizer and fertilizer compost sequentially give increase production of leaves at 2,39 tons/ha, 3,49 tons/ha and 2,94 tons/ha.Fertiler application by using liquid organic fertilizer produced highest profit, which amounted Rp.2.672.900, compared with normal income (without fertilizing) after reduced by production cost and other expenditures such as fertilized and fertilizing application cost (detail attached).

Abstract

The Resistance of Sengon against Pycnoporus sanguineus and Pleurotus djamor Using the SNI Methods (Standar Nasional Indonesia) 01-7207-2006Fungi is a organism which does not have chlorophyll and receives the energy resources by absorption system to the organic matters. A wood contains cellulose, hemicelluloses, and  lignin which in the wood decay fungi is very good needs. The kind of tree which the most acquainted with commercial trading till now is about 400 kinds of botanical (species). Around 80 – 85% of Indonesian woods had low class which it’s very easy attacked by wood decay fungi for instance Sengon. Kinds of it which potentially most decaying off the woods are Schizophyllum commune, Pycnoporus sanguineus, Dacryopinax spathularia, and Pleurotus djamor. This study was purposed to determine the potential of two kinds wood decay fungi to Sengon based on SNI Method (Standar Nasional Indonesia : SNI 01-7207-2006). Based on SNI 01-7207-2006 point out of wood weight loss percentage by the wood decay fungi knows that Sengon belong to IV - V resistance class (not resistant till very not resistant). The wood weight loss percentage was Sengon by P. sanguineus breed (31,09%) belong to V resistance class (very not resistant) and the wood weight loss percentage by P. djamor (20,51 %) belong to IV (not resistant).

Abstract

Schizophyllum commune Fr. As Indonesian National Standard Wood Resistance Test Fungi on Four Kinds of Community Wood : Sengon, Rubber, Tusam, and MangiumSchizophyllum commune Fr. is a vicious wood decaying fungi that in several cases could cause to 70 % weight loss. These fungi could attack various kind of woods (more than 25 wood species). It has been widely distributed especially in tropical area, and could easily grow in many conditions. This wood decaying fungi has an ability to decompose cell components of the woods through enzymatic processes from a complex to simpler form. Resistance of wood is strongly influenced by the content of extractive substances, although not all of these extractive substances are nocuous to wood destroying organisms. Based on the resistance, most common community woods have a low grade of resistance (grade III, IV, and V). This study aimed to determine the resistance of the four kind community woods which are sengon wood (P. falcataria), rubber (H. brasiliensis), tusam (P. merkusii), and mangium (A. mangium) against S. commune based on SNI 01.7202-2006. Parameters of the wood resistance against S. commune attack could be seen from the sample of weight loss. Based on the results of testing, it was known that sengon wood resistance was classified to a class IV-V (weak to extremely weak resistance to fungal attack) with the weight loss of longitudinal sengon and cross sengon respectively 32.2 and 15.7 %. Rubber wood resistance was classified to a class IV (weak resistance) with the weight loss value of longitudinal rubber and cross rubber respectively 13.8 and 12.0 %. Tusam and mangium wood’s resistance was clasified to a class III (moderate resistance) with the weight loss value of longitudinal tusam and cross tusam respectively 8.0 and 9.3 %. As for the mangium, the weight loss of longitudinal mangium and cross mangium respectively 6.3 and 6.3 %. Thus, the recommended wood as the control for the test of resistance against S.commune attack was sengon wood with the longitudinal direction of fiber. Fungi S. communne could use as the standard and was a recommended fungi for the the resistance test of the wood as it could cause the weight loss up to 3.2 % on sengon wood with the longitudinal direction of fiber.
