In Kalimas Rubber Plantation that his half of the land cleared and planted with sengon (albizia) covering 73 ha, are common in softwood plants use to pallets or finir. And there are some who planted Jabon (Jati Ambon) covering five hectares.
SP PUK Kahutindo PT. Karyadeka Alam Lestari whose members are associated with reduced diminishing his work with the felling of rubber land which the company developed its land became the property of land and planting sengon. PUK member until July 2010 was only about 218 members. Actually there are about 400an employees but their status as workers are seasonal workers and contract workers do not join into the union.
This is one problem or in which ever revealed and discussed in a board meeting Head Unit SP Kahutindo PT. KAL. By considering a few things from the contract workers are reluctant to enter for fear of association with risk. Well ... it becomes a classic problem in the world of workers. Workers will likely she chose to work with or may be paid under the UMK , and she feels safe with no association because he feels will work forever (hope workers).
Things like this happen as they may lack knowledge of the contract and seasonal workers about the association and the lack of understanding about the work rules. This problem is a problem with labor activists to solve the classic things that happened in working condition when this occurs.
Fresh servings of low here is because labor requirements and labor are very much equal.
Little exposure of cultivation and Jabon sengon
Sengon in the Latin language called Albazia Falcataria, including families Mimosaceae, family petai - petaian. In Indonesia, sengon has several regional names such as the following:
Java: jeunjing, jeunjing sea (Sunda), Kalbi, sengon Landi, sengon sea, or sengon sabrang (java).
Maluku: history (Ambon), brush (Banda), laughter (Ternate), and gosui (Tidore)
The most important part on the plant has economic value sengon is wood. The tree can reach about 20-30 feet tall with a trunk diameter of about 70-80 cm. Sengon rod shape and not rounded buttress. Outer skin is white or gray, no, grooved, and no peeling.
Sengon wood used for house building poles, container boards, cases of cash, furniture, fences, stalks and a matchbox, pulp, paper and other ainnya.
Sengon plant canopies shaped like an umbrella with lush leaves that are not too dense. Sengon pinnate leaves composed double compound leaves with small children and easy to fall out. Paraserianthes faded green leaf color, is used to cook food and also as an absorber of nitrogen and carbon dioxide from the atmosphere.
Sengon have a fairly strong taproot to penetrate into the soil, the root hair is not too big, not dense and not protruding surface of the soil. Hair root function to save the substance of nitrogen, therefore the soil around the tree becomes fertile sengon ..
Sengon flower panicles are arranged in the form of the size of approximately 0.5 cm -1, yellowish white in color and slightly hairy. Each flower is composed of male flowers bloom and female flowers, in a way that assisted pollination by wind or serangga.Buah paraserianthes shaped pod, flat, thin, and the length is about 6-12 cm. Each fruit pod contains 15-30 seeds. Shield-like shape and small seed if old seeds are blackish brown, rather hard and waxy.
Sengon plants can grow well in soil regosol, alluvial, and latosolic textured sandy clay or clay dust with soil acidity around pH 6-7.
Optimum altitude for the plant sengon between 000-800 m above sea level. Although this is still sengon plants can grow to a height 1500 m above sea level. Sengon including tropical plants, so to grow requires a temperature of about 18 Â ° - 27 Â ° C.
Jabon (JATI AMBON)
Crop Prospects Jabon
Jabon a timber plant that is generally used as raw material for plywood, the industry is a form of the timber industry has a relatively rapid growth.
This is because since the year 2002, an international organization in the field of timber industry or the International Trade of Timber Organization (ITTO), issued a requirement that tropical timber should not be exported, unless the wood is processed first
Jabon agribusiness trying to answer the challenges of the timber industry, especially plywood. this condition due to age harvested Jabon ie relatively short range of 4-5 years can be harvested and processed, so that the plant Jabon is the most appropriate alternative as the raw material of plywood or similar timber industry.
Wood processing results Jabon:
1. raw materials vinyr
2. raw materials for plywood
3. pulp (raw material for paper)
4. fruit crate
5. kids toys
7. concrete molds, etc.
requirements for the manufacture of plywood products:
1. cylindrical rod
2. branch-free stem height + 5 m
3. minimum diameter of 15 cm
4. texture and the direction of the straight fiber
5. density / specific gravity of 0.4 to 0.7 g / cm ³
other than that many farmers switched to crops planted sengon Jabon, this is due to rust disease that attacks plants sengon furu.
Jabon crop cultivation
Supplies of wood for the global market in 2001 just experienced a growing world shortage of sharp while at the same time a process of narrowing of the forest area. The fact that the market has been opened wide for anyone who invests in this timber.
Tropical forest area was damaged badly enough. Logging without balanced with efforts to become the leading cause of serious regeneration of this problem. Deforestation in tropical areas increases the temperature of the earth and the depletion of earth's oxygen levels. This evidence has contributed to an international organization timber (ITTO) to participate and determine the future of tropical timber trade. Organization ITTO has announced several steps to protect tropical forests that have been implemented starting in 2002. ahead of the next century, provided that the ITTO use of tropical timber must not be exported unless the wood is the result of processing. It is therefore necessary commercial timber cultivation program to produce quality wood with a higher value.
Jabon has several advantages compared with other forest wood plants. In addition to the growing power of a very fast, straight and tall, cylindrical trunked, branches will fall off by itself, nature is advantageous because it does not require pruning. The wood is yellowish white, very good with no visible fibers used for the manufacture of plywood (plywood), furniture, non-construction building materials, as well as sawn timber, crops Jabon menpunyai optimal ranges over 12 years but at the age of 6-8 years has been able in the cutting ( middle minimum 30).
- Self purning, shedding their own leaves.
- Plant upright, branches fall off by itself.
- Growth rate of tree diameter between 50-10 cm per year, height can reach 20 m at age lk. 12 years.
- Altitude place
- Sea level. = 10-1000 m above sea level.
- Rainfall = 1250 - 3500 mm / Th
- The estimated temperature = 100 C - 370 C
- The condition of the soil = sandy clay, red soil, calcareous soil, paddy soil
- PH soil = 4.5 to 7.5.
