Abstract

Various natural disasters such as floods and landslides that much happening at this time caused by environmental damage, esppecially upper watershed damage. Actual land use of forests in the Upper Citarum Watershed area is only 16.20%, still not meet the minimum area of forest (30%) base on UU No. 41/1999 about Forestry. Actual land use configuration in study site causes most of the region is dominated by the level of erosion hazard very heavy; total RTH covering 76.75% total study site; and approximately 58.25% of farmer households unable to meet minimum standards for decent living needs. By applying a multiple target linear optimization model Linear Goals Programming (LGP) that solved by General Algebraic Modeling System (GAMS) optimization software, recommended the optimal configuration of land use that can meet the ecological and economic objectives. These recommendations can decrease the erosion rate of 94.13% and reaching 72.97% areas that meet standards of TSL; reaching an area covering 87.39% of RTH; and increasing aggregate sector of food crops, plantations, and forestry farm household income amount 220.83%. Optimization model in this study are static models that do not pay attention to time, but this models produces marginal values and we can analyze the value of elasticity (Sensitivity Analysis) that can be known implications for optimization purposes in case of changes in conditions of objective optimization.

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

Estimation Correlation between Soil Characteristics Toward Reserved Carbon (Carbon Stock) in the Secondary ForestForest ecosystem is a unity which is closely related to the natural processes that have a complex role in maintaining the stability of constituent components of the ecosystem. The complex role of the forest is to maintain the stability of the global climate and soil protection. Related to global climate stability and international issues of climate change, forests have an important role as a source of carbon emissions (source) and carbon sinks and stores (sink). Related to the stability and the protection of soil, soil has characteristics that can help the growth of vegetation. The greater fertility of the soil, the greater expected growth of vegetation, it can be implied that the greater the carbon stored on the forest stand as well as on the under plants or litter. Therefore, this study aims to determine carbon deposits and the characteristics or site qualities in secondary forests, suspect and find out whether the characteristics of the soil has a high or low correlation to the carbon stored in secondary forest.Carbon stored in secondary forests of 41948,75 kg/ha of which 91,36%, equivalent to 38326 kg/ha of carbon stored in standing and 8,64%, equivalent to 3622,75 kg/ha of carbon stored in plants and litter below. Then the results obtained from soil characteristics include pH = 4,22, CEC = 17,05 me/100gr, C-organic = 2,86 %, organic matter = 4,97 %, N-total = 0,27 %, C/N ratio = 10,73 %, P-total = 2,22 ppm, K-total = 0,34 me/100gr, bulk density = 1,1 gr/cm3, and soil porosity = 57,96 %. When viewed overall, whether chemical composition and nutrient content of soil, conclude that the soil fertility status fall into the low category. This is because the content of the element P in the soil is so low that indicates a low soil fertility. After tested the correlation between soil characteristics and stored carbon (C-stock) is obtained that the pH, the C-organic, organic matter, total N, and K soil has a correlation or effect of carbon stored in the secondary forest.

Abstract

West Banyumas Forest Management Unit (WBFMU) is one of the forest management units in working area of Perum Perhutani Unit I Central Java, which has a Corporate Class (CC) of pine trees. Recently, the WBFMU intended to expand the acreage of pine stand in order to increase pine resin production. To achieve this purpose, WBFMU used the former logged over area of teak to be planted by pine. But,  problem arise because the planted pine seedlings showed unappropiate growth. So that, this research was aimed to determine the suitability of pine and limiting factors affecting pine growth in teak stands area at WBFMU. The results show that the suitability of land in the area of the former teak stands in plot 22 B is suitable (S) and plot 25 C is not suitable (N) for the development of P. merkusii according to bonita (site index).

Abstract

Reclamation is an effort to recover ex-mined land to its original function. Revegetation that can be conducted during reclamation is by planting acacia and cajuput. One of the reclamation results is carbon being absorbed and saved in biomass form. Therefore the amount of saved carbon can be estimated from potential biomass. Factors that can affect amount of biomass are age of standing tree, history of vegetation development, climate, and composition and structure of stand. The research shows that biomass potency in Block B (16,70 ton/ha) is larger than that of Block A (14,24 ton/ha). Estimation results of saved carbon potency show that it is directly related with biomass potency. Carbon saved in Block A is 4,14 ton/ha and that of Block B is 5,56ton/ha. This research shows that the ability of mixed stand of acacia and cajuput in saving carbon has not been optimum yet.Keywords: acacia, cajuput, reclamataion, carbon storage.

Abstract

Pulau Sebuku mangrove forest, South Kalimantan, is part of Pulau Sebuku Nature Reserve that needs to be protected as close as naturally. This study is aimed to explore the species composition and structure of mangrove forest in Pulau Sebuku. The results showed that Pulau Sebuku mangrove forest has low species diversity and high evenness. Total species of mangrove tree, forest regeneration, and other habitus consists of 10 species (Bruguiera gymnorrhiza, B. parviflora, Ceriops tagal, Rhizophora apiculata, R. mucronata, Sonneratia alba, Heritiera littoralis, Xylocarpus granatum, Nypa fruticans, and Acrostichum aureum). R. mucronata (bakau) is the dominant species in almost all locations of observation. Horizontal structure of Pulau Sebuku mangrove forests tend to L-form, which evolved towards a balanced uneven-age forest. Based on the floristic composition, structure and general appearance of the forest, mangrove forest communities in Pulau Sebuku grouped into 3 types, among others: shrub communities (bakau-perepat), young mangrove communities (bakau and bakau-lenggadai), and nypa community.Key words : forest structure, mangrove forest, pulau sebuku, species composition.

Abstract

The success of mangrove rehabilitations are influenced by various factors which one of them is the availability of seedling stocks over time. The knowledge about growth process and development of plants which will be used as seedlings are several factors of success of nursery development. Red mangrove (Rhizophora mucronata) is one species of plants which grows in mangrove forest. The conservation of this species is very important because its habitat is at the central zone of mangrove formation and has high reproduction over time so it can be easier to do rehabilitation. The aim of this research is to get the information about R.mucronata growth and development to get better cultivation technique. The treatments were planting of propagule that had pieces of fruit and planting of propagul without pieces of fruit. Based on this research, the planting of propagule without pieces of fruit gave significant effect toward the heigth and length of red mangrove (R.mucronata) propagules development.Key words : growth, nursery, propagule, Rhizophora mucronata

Abstract

Mangrove rehabilitation activities that are being undertaken in Muara village include seedling and planting activities for various species of mangroves, especially Rhizophora stylosa Griff. (bakau kurap). The villagers have problem to see the differences of ripe and mature fruit according to the activities. They often pick the ripe fruits that still have pieces of fruit although ripe fruits need preface treatment that take long time to be a seed. This study was conducted to obtain information about the development of bakau kurap growth in order to obtain a better cultivation technique based on propagules type at nursery, and the growth in the field based on planting treatments. Those are seedling in polybag, seedling non polybag, and direct seed from propagules. The result showed that during 4 months observation, direct seed from propagules treatment gave effect the highest of height growth about 3.19 cm/month. It suggested that rehabilitation activities should used direct seed from propagules at shallow area.Keywords: mangrove rehabilitation, Muara village, propagules, Rhizophora stylosa Griff.

Abstract

A Survey in West Java shows that Mindi (Melia azederach Linn.) is frequently found on the community forest lands as part of a mixed cropping system. These community forest lands have a potential to support food security. Soybean is an important food crop as source of protein in Indonesian. This study aimed to observe the growth of Mindi and soybean in an agroforestry system. This study used a split plot design which consists of two factors. The main factors was Mindi which planted using shade and without shade and the second factors are soybean variety (Argomulyo, Anjasmoro, Grobogan, and Wilis) using four replication. The results showed that differences of Mindi cropping method did not significantly affect the Mindi growth (height and diameter) which has been observed for three months. Wilis had the highest survival rate than others varieties. Both factor shade and varieties giving a very significant effect on the kedelai height at the 3-7 MST age. In addition, it's also very significantly affected the number of leaves trifoleat at the age of 3, 4, and 5 MST. Soybean production in Mindi agroforestry system gaves the higher yield than monoculture system at three months age.Key words: Agroforestry, mindi, soybeans, shade, variety.

Abstract

Natural disasters that occur in most areas of Indonesia would certainly give rise to a wide range of impacts on the physical, social, and economic life of the society. One of these natural disasters is landslides. KPH Lawu Ds is a owned company Perhutani, which produces pine resin. KPH area Lawu Ds are generally located in areas that have a steep slope has an area prone to landslides are quite extensive. Therefore, in carrying out forest cultivation of plants which are generally homogenous need additional types of vegetation can reduce the level of vulnerability to landslides. Landslides can also be regarded as a form of land use that have little or no attention to soil conservation techniques, but in this study only look from the vegetation in developing soil conservation techniques in homogeneous plantation forests in the forest management unit areas KPH Lawu Ds. Therefore, the purpose of this study was to obtain the right local plant species as the plant are prioritized and appropriate to prevent the occurrence of landslides and obtain the shape and pattern of cultivation. Data analysis using descriptive analysis of qualitative and models that fit the preferences of local preferences of plants grown on land prone to landslides in RPH Cepoko by using the method of AHP (Analytical Hierarchy Process). Alternatives are obtained based on the plants prioritized is clove, coffee, chocolate, calliandra, Leucaena leucocephala, durian, Swietenia macrophylla, Aleuriteus Moluccana, Paraserianthes falcataria, Pangium edule, Anacardium occidentale , and Sterculia foetida and cultivation techniques of forest vegetation on the sides of the plant adjusted based onsolum soil, slope and vegetation cover of pine with dense composition, middle and rare on research plots in the area of KPH Lawu Ds and planting distance is determined by the density of the canopy.Key words: mitigation, native plant species, preference, cultivation techniques.
