Brick is a building material that has a function as a room sealer. Its larger size, when compared to red brick, makes bricks more in demand in the market. Improving the quality of bricks needs to be done to meet the needs of the building. The use of added materials becomes one of the things that can be considered to improve the nature and quality of bricks. This research aims to find out the strong press and absorption of bricks with the use of coconut pellet fiber. The research was conducted experimentally with the manufacture of test objects in the laboratory. The test object used is in the form of a beam of 30x15x10 cm. The percentage variation of coconut fiber is 5%, 10%, and 15% of the weight mass in bricks. The tests carried out include a strong compressive and water absorption test with reference to the Indonesian National Standard (SNI). The results of water absorption tests obtained the optimum value in bricks with a mixture of 5% fiber which is 6% of the mass of the weight of the brick, while the minimum value is in the brick, 15% fiber, which is 10%. While the compressive strength results get the optimum value on the 5% fiber mix variation, which is 20.1 kg/cm², and the minimum value on the variation of 15% fiber is 8.8 kg/cm². From these results showed that bricks with coconut pellet fiber have not been able to improve the quality of bricks.

Inorganic Waste

Garbage is a serious problem if it is not managed properly, both organic and non-organic. Inorganic waste, for example, plastic, metal, glass, and charcoal from coal combustion are difficult to decompose in the soil. HDPE (high-density polyethylene) plastic is one type of inorganic waste that is difficult to decompose, but this plastic can be recycled. The objective of the study is to develop light cement blocks by using the waste of HDPE, coal bottom ash and cement. The research guide was referred to SNI (Indonesian National Standard). The SNI-03-6825-2002 is for testing of the compressive strength and SNI 03-0349-1989 for the testing of the water absorption. The size of the specimen was 5 x 5 x 5 cm. In this study, the compositions of HDPE: coal bottom ash were varied by 70%: 0%, 60%: 10%, 50%: 20%, and 40%: 30%. The Holcim cement was 30% of the volume fraction. Testing was conducted after the specimens stay in 7 and 28 days. For the 7 days old of specimens, the highest compressive strength has resulted from 50%:20% composition with the value of 5.88 N/mm2. For the 28 days old specimens, the highest compressive strength was 8.34 N/mm2. The lowest water absorption test was delivered by the more coal bottom ash in the composition of 40%:30%. It was 16.971%. The more coal bottom ash, the less water absorption. The mean of specimens density was 1.076 gr/cm3. The result of the research shows that recycles HDPE and coal bottom ash as concrete block meet the required strength.

<em>The most widely used material as a house wall is red brick, which is relatively cheap and safe to weather compared to other materials. Red bricks are usually in the manufacturing process by traditional means and fabrication. In general red bricks require additional materials of rice husk in the process of making. Much of the "starchy" waste material widely found in Klaten that is not currently utilized, is expected to be used instead of rice husk which is one of the red brick material mixtures.This research will be conducted brick test with mechanical behavior test which includes density test, water absorption test and compressive strength test with red brick made from rice husk mixture as comparison with analysis result of mixture of starch onggok waste. The result of this research is compressive strength of brick with mixture of rice husk larger and has a small water absorption compared with compressive strength of brick with mixture of onggok.</em>

Pre Treatment

The beauty packaging industry uses paints for colouring to attract the consumers. The generation of hazardous paint waste need to be well managed to minimize negative impact on the environment. This research is intended to investigate the utilization of paint waste as a raw material of paving block. The variations of waste addition are used to study the compressive strength of paving based on the mixture of sand and cement. The addition of paint waste by 2.5 % w/w diminishes the compressive strength from 25.6MPa to 9.9 MPa. The compressive strength for the addition of 5%, 7.5%, 10%, and 15% are 7.8, 3.1, 3.2 and 2.2 respectively. The reduction of compressive strength due to the addition of paint waste indicate that the direct utilisation for production of paving block is not viable. Water absorption test value not meet the specifications of paving block SNI 03-0691-1996 which range from 1.67%-11.38%. The pre treatment of waste such as drying and grinding to eliminate the solvent is indispensible.
