Forest as the financial capital for development has important roles in economic development of Kotawaringin Barat Regency. Commonly, forest is a large area of land where flora (trees) and fauna (animals) exist. It can produce woods and other products for human consumption (production function), regulate the water system for human life, prevent flooding and sea water intrusion (protection function), and preserve many species of plants and animals and ecosystem (conservation function). Economically, forest as the source of woods, rattans and other products provided foreign exchange for the country during 1980-1990; this case placed the subsector of forestry as one of the prime movers in Indonesia’s economy. The purpose of this research was to analyze the extent of the foresty’s contribution to the economic development and social welfare in Kotawaringin Barat Regency. The research methodology was conducted by: a) interview, b) observation / field surveys and c) documentation (supporting data). The results showed that the contribution of forestry subsector in the economic development and social welfare of Kotawaringin Barat reached IDR 38.6 billion in 2011. Keywords: Contribution, Economy, Welfare

Charcoal briquettes can be alternative energy and can be produced from A. mangium wood. This type of wood is commonly found in Central Kalimantan. The purpose of the study was to determine the characteristics of charcoal briquettes produced from A. mangium wood stems, branches, and twigs that referred to the Indonesian National Standard (SNI-01-6235-2000) using a Completely Randomized Design method with a total sample of 15 pieces. The data obtained were tested for homogeneity using the SPSS application and statistically analyzed using the Analysis of variance (Anova). The treatment had a significant effect, then continued with Duncan's Closest Real Distance Test. The results obtained generally meet the Indonesian National Standard (SNI-01-6235-2000) regarding charcoal briquettes except for water content, ash content, and volatile substances. The best data from the stems, branches, and twigs of A. mangium was the stem which produced 8.94% moisture content, higher density of 0.73g/cm3, ash content of 12.60%, bound carbon of 50, 60%, volatile matter content of 27.86%, compressive strength of 65.06 kg/cm2 and calorific value of 6923.08 cal/g.

Building portals with profile steel construction are very commonly used. However, with the potential for earthquakes in Indonesia which has a very large risk, the geometry of the portal must be given structural elements that can increase the lateral stiffness of the structure. One of the innovations to improve the lateral stiffness of the building portal is to provide a structural element in the form of a shearwall. Steel plate shearwall is one of the structural elements that serve to withstand lateral loads on a building, one of which is earthquake loads. Steel plate shearwall has a high slenderness rate. So that the lateral load will cause a large buckling problem in the shearwall plate. Corrugated steel plate is one of the innovations to solve the buckling problem. The purpose of this study was to analyze the effect of the wave plate shape on the shearwall. This research was conducted using numerical analysis using the ANSYS program to see thebehavior and strength of the steel plate shearwall. The shearwall models analyzed are beam-column frame type, shearwall with flat steel plate, and shearwall with corrugated steel plate, which is given a static lateral load at one end. This study shows that the yield load on the beam-column frame is 1400 kN, the shearwall for the flat steel plate is 1850 kN, and the shearwall for the corrugated steel plate is 2035 kN. The corrugated plate's geometric pattern obtained an increase in yield load of 9% compared to the flat plate. The buckling pattern that occurs in the flat plate shearwall and wave plate is diagonal shear buckling in the center area of the plate.

The Analysis of Cost and Income Must Yoan Farm Honey Bees, Kalampangan Village, Central Kalimantan. Honey bee cultivation in Central Kalimantan, especially the city of Palangka Raya, has the potential to be developed, considering the natural resources are very supportive and meet various location requirements for honey bee cultivation, in addition, especially honey bee farmers in the Kalampangan village have started this business, but stopped in mid this is due to a lack of information in terms of analyzing costs and income in this business, many think they will experience losses in this honey bee business while honey bees are a very good business because all of honey bees can produce economic resources starting from bees to waste and in the village of Kalampangan, the majority of people cultivate crops, so it is very good for natural pollination assisted by honey bees. Therefore, a proper analysis of the business being carried out is needed to find out the problems that occur at the research site and the solutions that will be taken. The method used consists of: 1. calculating fixed costs and income 2. Calculating honey bee business profits 3. Calculating break even point (BEP). 4. Calculating the feasibility of a honey bee business. The results of the study, 1. The cost of Rp. 355.400.000, and the amount of income is Rp.901.090.000, 2. Profit earned is Rp.545.690.000, 3. BEP (Break Even Point) in rupiah is Rp.231,806,626 and BEP unit is 1,825.71 4 The level of business feasibility, the value of the B/C Ratio is 2.54

One of the efforts to increase income is utilizing non-timber forest products in the form of home industries. One of the non-timber forest products utilized by the community and have a business opportunity is the Nipa plant (Nypa fruticans Wurmb). It grows along rivers near estuaries to rivers with brackish water influenced by tides and is included in the mangrove/brackish forest type. The research aimed to analyze the utilization level of nipa (Nypa fruticans Wurmb), examine the income level of the nipa roof craftsman, measure the contribution level of the nipa roofing business to family income, and analyze the relationship between the income level and the utilization of nipa (Nypa fruticans Wurmb). Data was sampled using the census method. The respondents were the craftsmen of nipa roofs (only ten people were still active in making nipa roofs). The required data includes the utilization of nipa resource products, production costs, total revenue, selling price, income from the nipa roofing business, and income from other family members. The results showed that the total production of nipa palm roofs was 303,840/year. The average income of nipa roof craftsmen was Rp10,732,200/year. The income contribution of the nipa roof craftsmen to family income was medium (55%). The utilization of nipa forest resource products had a very strong and positive relationship in increasing the income of nipa roof craftsmen with a correlation value of 0.842.

Rattan natural resources at the research site are a source of community business in order to improve the local community's economy. The research objectives identify the form of rattan utilization, analyze the income level of the community, analyze the contribution of rattan craftsmen's business to the level of welfare, analyze the marketing process and marketing efficiency of rattan. The method used is by describing the form of rattan utilization, calculating the income of rattan craftsmen with other business income, dividing the income of rattan craftsmen to the total income of craftsmen, subtracting the selling price at the consumer level with the purchase price at the producer level, while efficient marketing divides the total cost of marketing against the total value of the product. The results showed a total of 1,044 units of finished rattan products/year consisting of bracelets, small bags, large bags, mats, serving hoods, hats, and baskets. The average income of the rattan craftsmen (respondents) is Rp. 29,726,538/year. The contribution of rattan craftsmen to the income level of the people in the research location is 38%. The total marketing margin at the intermediary producer level is Rp. 151,000 with an average marketing efficiency of 13.84
