Abstract

AbstractAbstract. This study aims to determine the effect of optimal physical properties and microstructure on particleboard samples. The percentage variations of cocoa pod peel powder mixture, styrofoam with epoxy resin adhesive were sample A (69:0:30), sample B (68:2:30), sample C (67:3:30), and sample D (66:4:30). 6:30). The materials were compressed were a hot press and a conditioning time of 14 days. sThe most optimum particleboard sample was found in sample B with values of density, moisture content, and thickness expansion, respectively 0,80 g/cm2, 7,74%, and 9,32%, and met the standards of SNI 03-2105- 2006. The surface shape of the particle board morphology in sample B shows the composition of the material with the adhesive binding optimally so that there are very few empty spaces or cavities. Keywords: cocoa pod husk powder, styrofoam, particle board, epoxy resin.

Abstract

This test was carried out to reduce waste in coconut empty fruit bunches and to determine the characteristics and microstructure of the particle board surface.  The samples used consisted of bamboo powder and oil palm empty fruit bunches with gambier adhesive and urea formaldehyde with variations including: 10%:75%:15%:11%;  20%:65%:15%:11%, 30%:55%:15%:11%, 40%:45%:10%:11%.  The particleboard was printed and pressurized using a hot press of 16kg/cm2 for 15 minutes at a temperature of 120 oC, with a drying time of 14 days.  The test parameters include: density, moisture content, thickness expansion, and microstructural analysis using SEM (Scanning Electron Microscopy) which refers to SNI 03-2105-2006.  The characterization of particleboard produced in the density test is 0.66-0.74 g/cm3, the water content value is 2.4-6.9%, the thickness expansion value is 7.2-12%.  Based on the percentage value of the density of the resulting particleboard is a medium density particleboard.

Abstract

Research Hydroponic plants are an alternative solution for urban communities so that they can grow crops at home and do not require large areas of land. However, hydroponic farmers sometimes find it difficult to improve plant quality because they are busy and do not have time to take care of the condition of the plants. Therefore, an automatic system was designed to improve the quality of hydroponic plants. The test results show that this tool is able to control pH levels, namely when the pH is too acidic, the base pH pump will turn ON to normal, when the pH is too base, the acid pump will turn on to normal. To control nutrient solids, namely when nutrients are reduced, the nutrient pump will be ON and when there is excess the water pump will be ON to neutralize it as needed by the plant every week, controlling day and night conditions, namely during the day the system will work to drain the plants and at night the hydroponic irrigation will stop for efficiency tool, and all sensor values are displayed through the LCD which monitoring the activity of the tool. Therefore, from the system that has been designed, the tool is able to work automatically on the application of automation hydroponic planting system based on acidity, nutrient concentration and lighting.

Abstract

Research has been conducted on The Manufacture and Characterization of Charcoal Briquettes From Palm Shells And Hazelnut Shells. This study aims to determine the influence of variations in the composition of palm shells and hazelnut shells on the calorific value, moisture content, and ash content in the resulting charcoal briquettes. This study was conducted by carbonization method, mixing, printing, drying and briquette youthfulness analyzed with test parameters namely moisture content, ash content, and calorific value. The results showed a mixture of palm shell and hazelnut shell can be used as briquettes. In this study briquettes with optimal composition were a mixture of variations of palm shell and hazelnut shell 60% : 35% with a moisture content of 6.25%, ash content of 11.37% and a calorific value of 5129.45 cal / gr.Keywords : Palm Shell, Hazelnut Shell, Moisture Content, Ash Content, Calorific    Value

Abstract

Abstract: Research has been carried out on the analysis of the physical properties of paving blocks from egg shell powder. This study aims to determine the physical properties of water absorption, density and porosity in the resulting paving blocks. The samples used were eggshell powder, cement, and sand with a ratio of 0%:40%:60%, 5%:35%:60%, 10%:30%:60%, 15%:25%:60%, 20%:20%:60%. The FAS used was 0,56 and the drying time for the paving blocks was 28 days. The results of the analysis of the physical properties of paving blocks produced at 0% variation have a water absorption value = 8,08%, density = 2,29 g/cm3 and porosity = 13,31%, at 5% variation has a water absorption value = 8,10%, density = 2,18 g/cm3 and porosity = 13,94%, the 10% variation has a water absorption value = 8,63%, density = 2,17 g/cm3 and porosity = 14,41% , the 15% variation has a water absorption value = 8,83%, density = 2,16 g/cm3 and porosity = 14,94%, the 20% variation has a water absorption value = 9,10%, density = 2 ,14 g/cm3 and porosity = 16,82%. Keywords: Paving Block, Eggshell Powder, Physical Properties.
