Abstract

The use of wood as industrial raw material has increased every year, while the availability of wood has decreased. Besides that, the increase in plastic waste is also a big problem. By making fiberboard from coconut coir fiber and recycled polypropylene plastic, it is hoped that it can increase the added value of coconut coir so that it can become a substitute material to replace the increasingly limited use of wood and also as a way to minimize polypropylene plastic waste in the environment. Based on the test results, the best fiberboard is a fiber board with a random arrangement of fibers with a pressing time of 60 minutes with a moisture content value of 1.18%, a density value of 0.48%, a water absorption value of 4.14%, a thick swelling value. amounted to 4.52%, the MOE value was 4050.80 kg/cm3, and the MOR value was 242 kg/cm3. Overall, the random fiber arrangement fiberboard with a pressing time of 60 minutes has met the SNI 03-2105-2006 standard, but only the MOE value has not met the standar

Abstract

The development of the laundry industry needs attention because generally laundry industry players dispose of waste directly into receiving waters, which causes the water environment to become polluted. Therefore, it is necessary to conduct research to reduce levels of pollutants (BOD, COD, pH, and phosphate). One of the processing techniques that can be used to treat laundry wastewater is the adsorption process. Adsorption occurs because of the attractive forces between the adsorbate molecules on the adsorbent surface. In this study, bottom ash was used as an adsorbent to absorb pollutant levels from laundry waste. This study aims to determine the quality of the absorption of bottom ash adsorbent on the reduction of pollutant levels from laundry waste and the effectiveness of reducing pH, phosphate, COD and BOD levels on variations in the time and weight of the adsorbent used. This laundry waste treatment goes through several stages such as raw material preparation, initial analysis, absorption of laundry waste using bottom ash and final analysis. The results showed that the values of COD, BOD, pH and phosphate after absorption were obtained values of 354.8 mg / L, 129.2 mg / L, 7 and 0.095 mg / L, respectively.

Abstract

The use of detergent in washing activities is increasing in line with the population growth rate every year. Laundry waste generated by the use of detergents contains active ingredients which are harmful to the health of living things and can damage the environment and cause eutrophication. One method of processing that can be used to treat laundry waste is by using activated carbon as an adsorbent. This study aims to determine the best conditions for treating laundry waste using activated carbon and to be able to utilize laundry waste as a source of phosphate for plant growth. Laundry waste is treated with the addition of activated carbon as much as 5, 10, 15 and 20 grams per one liter of laundry waste with a variation of time 20, 40 and 60 minutes and a constant stirring speed at 200 rpm. The parameters analyzed were pH, COD, BOD, phosphate concentration and the effect on the growth of chili plants observed for 9 weeks. The results showed that the pH level remained constant at a value of 7, and the BOD, COD and phosphate concentrations decreased to 53.6, 227.3 and 0.178 mg/L, respectively. The adsorption isotherm model is closer to the Freundlich isotherm model with R2 value of 0.9835-0.9998. And there is no significant effect on the provision of laundry waste after treatment on the growth of the tested plants.

Abstract

Composite letter sign can be made from particle board. This study aims to produce composite letters sign in the form of particle board with the raw materials of Empty Bunch of Oil Palm, Teak Sawdust and Low Density Polyethylene (LDPE) recycled plastics using the hot press method. This study used variations in the concentration of NaOH in the alkalization process. The concentration variations used were 0%, 1%, 2%, 3%, 4% and 5%. The particle board was analyzed based on SNI 03-2105-2006 including moisture content, water absorption, density, thickness expansion, modulus of rapture and modulus of elasticity. The results of the analysis showed that in the test of water absorption, density and thickness expansion did not significantly influence the variation in NaOH concentration. However, in the test of water content, modulus of rapture and modulus of elasticity have an effect, this is indicated by the increasing concentration of NaOH, the more the quality of the particle board increases. The particle board used NaOH 5% concentration variations became the most optimum with water content data of 2.85%, modulus of rapture of 194.65 kgf/cm2 and modulus of elasticity of 7007.90 kgf/cm2

Abstract

Garlic has properties for health, such as preventing the presence of bacteria and cancer, garlic contains allicin compounds and contains vitamin C, where these compounds can boost the immune system to fight germs. Therefore, garlic can be alternative to maintain endurance, by fermenting it into a garlic herbal product counseling aims to foster creativity, and create anattitude of caring for the environment, as well as understanding the positive impact of natural resource processing on the environment, health, social and especially the economy. This community service activity is also carried out to help take advantage of the potential of partner areas and help increase the income of the local community, as an alternative creativity in overcoming the direct impact of post-Covid-19 on the economic aspect. Counseling in the form of presentations, short lectures, and demonstrations with the production of black garlic.
