TATA RUANG DAN BENCANA

After the box containing the crumbs comes out of the Dryer machine, then the contents of the box dryer will be cooled to 40 degrees Celsius. This cooling is needed to avoid mold growth on the final result. The final result will be wrapped in plastic. Hot temperatures will result in condensation of air inside the plastic. This dew can trigger fungus. The product plasticizers can melt so the products will become sticky to each other. The Plasticity Retention Index (PRI) value will drop due to the heat retained in the package. Before being brought to the packing process, the Box Dryer is first removed its contents (in the form of crumbs in the form of pads that have dried) and placed on the sorting table. Results that come out of the Dryer will be separated visually between results that meet specifications and results that come out of specifications / out spec. Results that are out of spec are usually results that still contain raw rubber / virgin rubber / white spot (marked white spots a...

The drying temperature is set at 60 - 130 degrees Celsius. The total drying time taken is approximately 4 hours. Dryer operator has the duty to keep the crumbs completely dry optimally. Less dry crumbs usually result from white spots or virgin rubber on the final product (bandella). Meanwhile, if the drying temperature is too high or the drying time is too long then the results that come out of the dryer become slimy and sticky. This slimy and sticky rubber condition is an initial description that the quality parameters of the PRI (Plasticity Retention Index) failed to be obtained. The drying process in the Dryer uses hot air. Hot air is produced by Heat Echanger. The heating component contained in the Heat Exchager is a pipeline containing hot oil. The air that passes through the pipeline containing hot oil is then turned into hot air and then passed into the dryer to dry the rubber crumbs in the dryer box. The air is then circulated again to the Heat Exchanger so that with this circu...

Before entering the drying process, the blangket will be attenuated first with a Schreder machine. The purpose of this attenuation is to obtain sufficient surface area for raw materials to contact with hot air in the Dryer machine. The shape of the crumbs also allows the raw material to be printed in a Box Dryer (often also called a trolley), making it easier for packing. The crumbs produced by Schreder will then go into a long tub of clean water (functioning partly washer and transport media) in front of the Schreder. From the tub, the crumbs are then transferred through a pipe with a Hydro Cyclon pump to the Box Dryer. There are 2 people who are tasked to ensure that the remnants enter the Box Dryer properly and correctly (position on the right and left side of the box dryer). A Box Dryer has a capacity of 120 Kg Dry. Weakness must enter the box in a natural way and there should be no emphasis on crumbs. This is to avoid compacting in crumbs. Solid weakness makes it difficult for hot...

Result of grinding the crumbs into sheets about 60 cm wide with a thickness of 6-7 mm. Weakness has turned into a homogeneous sheet / Blanket. Blanket rolled and then sent to the Maturation Warehouse for the "Curing" process. 1 roll weighs approximately 350 kg (wet weight). The level of dry rubber in a wet blanket produced is around 70% (pre-maturation value). Maturation Blangket drying is done by arranging sheets in the clothesline. Hanging process lasts for 15-20 days. Rubber raw material will dry faster in the Dryer process and the possibility of fewer white spots. Fig. Blangket arranged in Maturation Warehouse Each clothesline will be arranged so that each blanket can be identified according to their age and owner with adequate ventilation space The purpose of drying blankets is to maintain the PRI value and to participate in reducing the Moisture Content in Blanket. Usually the level of dry rubber after maturation for 15-20 days is 80-90%. The PRI value is a measure of t...

The main purpose of grinding milling is to get the uniformity of raw materials with micro processes and make them in sheet form. 2. Micro Blending Process homogeneous activities occur by grinding crushes which are arranged so that they overlap each other in the mill. 3. This "overlapping" process forces the rubber crumbs to become one piece which will eventually form a sheet. 4. Milling is done using a Crepper grinder. 5. Crepper Rolling Mill is made threaded / floral motif so that the e...

Raw materials come from all regions in Bengkulu province. The receipt of rubber raw material that is dropped from the truck is then piled temporarily on the Loading Ramp floor before entering the processing. Hoarding is done by dividing raw materials into groups according to age to ensure the FIFO system runs.  Types of raw rubber shaped like a slab and cuplump. Raw materials received will also be sorted from non-rubber objects (contamination). Examples of these contamination items include: 1. Plastic strap 2. Broken latex bowl 3. Raffia cords 4. Scrap / latex pull 5. Pieces of wood 6. Leaves 7. Plastic gunny tears 8. And others These objects (contamination) will be collected and returned to the sender

Rubber plant comes from the Latin language named Hevea braziliensis. Rubber plants were first found in the Amazone river valleys (Brazil). When Christophel Columbus discovered the American continent in 1476, he was astonished to see locals (Indians) playing ball using a material that could bounce when dropped on the ground. The ball is made of a mixture of roots, wood, grass, and material (latex) which is then heated on fire and rounded into a ball. Long before this rubber plant was popular, natives in various places such as the United States, Asia and South Africa used other trees that also produced sap. This sap is produced from the Castillaelastica plant (family moraceae). The plant is no longer used because it is less popular than rubber plants. In Indonesia, the rubber plant was tried to be cultivated in 1876 and was first planted in the Bogor Botanical Gardens. Rubber plants can grow tall and trunked quite large. Mature tree height can reach 15-25 meters. The trunk usually grows ...
