A. Title


B. Background

Human needs to make the exploitation of forest timber occur massively. This problem has not become a stranger in the ears of people, especially people of Indonesia. Forest exploitation on a large scale resulted in a barren forest. Being denuded forest is the main factor to the disaster, including flood, erosion, and the warmer again the problem of global warming (global warming). Needs high society will lead to higher use of timber harvesting in the wild, or better known by illegal logging. Until now needs most is still filled timber from natural forests. Supplies of timber from natural forests each year is reduced, both in terms of both quality and volume. This is due to the range of the harvest that is not balanced with a range of planting times, so the pressure on natural forests bigger. On the other side of the wood demand for industrial raw materials increased, this means the supply of raw material in the timber industry has become increasingly difficult, if only relying on wood from natural forests (Boerhendhy, 2006). Wood as a commodity forest products people still ranked “less important” than other commodities by most farmers. This is because the wood can not provide quick results, not a daily consumption of commodities and so forth. Hence the structure of household incomes of farmers, forest is a side or additional revenue. (Hardjanto, 2000). Indonesia is an archipelago that long to reach 81,000 kilometers of coastline about 3.8 million ha of land is a traditional coconut tree plantation, the land area is 3.6 million ha of which is the garden belongs to the people, that is why in the affairs of the fruit of this one, Indonesia including number one in the world to successfully defeat the domination of the Philippines since a few years ago. Coconut is the agricultural commodity that the whole part of this plant can make money. Starting from the root, until the leaves have produced various types of products, such as building materials, furniture, home furnishings, food and beverages. Unfortunately the abundance of existing natural resources and the creativity has not yet produce high added value and also great benefits for society. In fact, from the palm can produce high-value products, among others, can be processed into a means of hygiene, such as soap, cosmetics, and medicines, while the coconut is now busy talking sabutnya because it has benefits for the community and is part of the coconut coir large enough from coconuts, which is 35% of the total weight of fruit. According to Maria Ulfa (2006:1) coconut coir fiber and cork consists of connecting one fiber with other fibers are a valuable part of the fiber. Each coconut contains 525 grams of fiber (75% of fiber), and cork 175 grams (25% of fiber), coconut business still provides a wide opportunity, because let alone to meet export needs, the need for fiber in negripun still many who can not be met . because of the many producers who were forced to change roles with coir fibers / spon.beberapa employers in North Sumatra, West Java and East Java who claimed to be besieged inside. The use of coconut husk for this is usually for making ropes, mats, seat fillers, car seats, mattresses, decoration material and recent results can be processed into cocofibre (fiber) and cocodust (pulp from the fiber), and there is another byproduct of the processed fiber coconut overseas market demand: cocopeat. As with any organic material from soil mixed with compost, cocopeat can also be used as a medium for ornamental plants. Coco has several properties that is durable, strong against friction and not easily broken, resistant to water (not easily decompose), resistant to fungus and pests, and not inhabited by termites and rats, but it also has heat resistant properties and strength test indirect tensile, strength comparable to steel. Banana stem is underutilized material, which more clearly only used as a place to put the puppet on puppet stage. People are starting to look a banana trunk as alternative base materials, especially the processing of food. Particle board is one of the needs of the community-based primary timber. But there is no alternative to particle board-based products other than wood, particle board but is a very high demand of the society. According to the Ministry of Forestry quality particle board covering disability, size, physical properties, mechanical properties, and chemical properties. In standard particle board issued by some countries is still possible differences in criteria, how to test, and requirements. However, by and large the same. Defect In Standard Indonesia Year 1983 not to distribute quality particle board based on disability, but in 1996 there are 4 standards of appearance quality particle board according to disability, namely: A, B, C and D. Disability was assessed in coarse particles on the surface, powder stains, oil stains, scratches, adhesive stains, broken edges and porous. Size assessment of length, width, thickness and elbows are on all standard particle board. In this case, the introduction of tolerance that is not always the same in each standard. In terms of tolerance has been, distinguished for the second smoothed particle board surface, a surface smoothed and not smoothed surface. Physical Properties Density of particle board is set in the same way on all standards, but its requirements are not always the same. According to the standard requirements of Indonesia Year 1983 0.50 to 0.70 g/cm3, while according to Standard Indonesia Year 1996 requirements from 0.50 to 0.90 g/cm3. There is a standard particle board which classified according to density, ie low, medium and high. The water content of particle board is set in the same way on all standards, namely the oven method (method of weight reduction). Although the requirements are not always the same water content in every standard, the difference is not large (less than 5%). Development of thick particle board determined after the sample is soaked in cold water (room temperature) or after immersion in boiling water, the first way are made to the particle board interior and exterior, while the second way for particle board exterior only. By Standard Indonesia Year 1983, for particle board exterior, thick development determined after boiling 3 hours, and after boiling 3 hours and then dried in an oven 100 ° C until the sample weight remains. There are no interior particle board thickness tested development, such as type 100 by Standard Indonesia Year 1996, while for type 150 and type 200 tested development thickness. According to the FAO standard, when measuring the thickness of it provided for the development of its water absorption (absorption). Mechanical properties Strength (strong) flexural tested in the dry state generally involves fracture and modulus of elasticity modulus. In Indonesia Year 1983 Standard modulus only broken only, while in Indonesia Year 1996 Standards include fracture and modulus of elasticity modulus. In addition, the standard is broken modulus test on wet conditions, ie for particle board type 150 and 200. When the particle board, including type I (exterior), fracture modulus testing in wet conditions after the sample is soaked in boiling water (2 hours) and then in cold water (room temperature) for 1 hour. For particle board type II (interior) fracture modulus testing in wet conditions after the sample is soaked in hot water (70 ° C) for 2 hours and then in cold water (room temperature) for 1 hour. Persistence of internal adhesion (tensile strength perpendicular to the surface) are generally tested in the dry state, such as the Standards of Indonesia in 1996. In Indonesia the year 1983 standard test performed in the dry state to quality particle board I (exterior) and quality II (interior). Tests on wet conditions, ie after immersion in water education (2 hours) is done only on the quality I just particle board. Strength (strong) hold the couplers were tested in the direction perpendicular to the surface and parallel to the surface and at a dry state only. According to Indonesia in 1996 Standard testing is done on a particle board thickness above 10 mm. Nature Chemical Emissions (removable) of formaldehyde can be considered as chemical properties and particle board. In Indonesia Standard 1983, has not been mentioned on the emission of formaldehyde from particle board. In Indonesia Standard 1996, stated that if required to do the classification based on formaldehyde emissions. In Indonesia in 1999 Standard on formaldehyde emissions at wood panel contained formaldehyde emissions testing and requirements on particle board ( To better utilize the banana stem, the authors wanted to examine alternative banana stalk as a raw material substitute for wood particle boards with a comparison of particle board of wood based on the market, then this student creativity through the program writer lifted the title “coco PROCESSING INTO PARTICLE BOARD WITH TRUNK BANANA IN INTERIOR BUILDING AS upholstery. ”
