Abstract

This study aims to determine the effect of thickness variations on the sound absorption coefficient of acoustic material from corn stalks. The study was conducted by making acoustic board samples from corn stems with Polyester Resin adhesive. In this study the thickness of the acoustic boards used were 0.7 cm, 1 cm, and 1.5 cm. The amount of frequency used is 250 Hz, 500 Hz, 1000 Hz, 2000 Hz. Based on the results of the research, the absorption coefficient value is proportional to the thickness, where the greater the thickness of a material, the lower the coefficient value produced. In the thickest sample with a thickness of 1.5 cm for a frequency of 250 Hz, the absorption coefficient value is 0.177, while at the frequency of 2000 Hz the absorption coefficient value is 0.084.

Abstract

This research aims to find out the best composition of brake lining materials from the shell of candlelnut and bamboo fiber through hardness testing and wear and tear of brake lining materials. The method used is direct emphasis using the Universal Testing Machine and Oghosi tools using the High Speed Universal Wear Testing Machine (Type OAT-U) Oghosi tool. Brake lining materials consist of shell powder of candlenut and bamboo fiber and then added aluminum powder and polyester resin with percent of specific composition for each sample. The results of this study were the five samples having lower wear value than the market but only the sample 4 with the composition of 15% of the shell powder of candlenut, 30% bamboo fiber, 15% aluminum powder and 40% polyester resin recommended as alternative material of brake lining because of its hardness close to the hardness of the material of brake lining of the market is 13.5 BHN and its wear is 2,96 x 10-6 mm2 / kg.Key Words: Strong Test of Pressure, Wear of Brush, Bamboo Fiber, Shell Powder of Candlenut, Aluminium Powder, and Resin

Abstract

This study aims to determine the effect of fineness to compressive strength of cement mortar. Mechanical parameters measured are fineness and compressive strength. From these test results, lead to the conclusion that the overall mechanical properties of the cement and mortar for all treatments meet the Indonesian National Standard (SNI) in 2004, the highest level of refinement that is 410.8 kg/m2, while the lowest is 387 kg/m2. For the compressive strength at age 3 days produces the highest value is 181 kg/m2, while the lowest is 143 kg/m2, at the age of 7 days resulted in the highest value is 242 kg/m2, while the lowest is 204 kg/m2, at the age of 28 days produces the highest value is 350 kg/m2, while the lowest is 265 kg/m2. Concluding that the more finely granular cement eat the higher the compress strength.

Abstract

This experiment aims to know the influence of the increment of glass bottle waste to the pressure power, the water absorptive power and the density of the brick material and to know the comparison of the increment of glass bottle waste composition value to the brick material which produces the pressure power, absorptive power and the density match with standard value. This experiment uses tool test like beam with a size long 11 cm, wide 11 cm, height 5 cm with some various of the aggregate of glass bottle composition 0 %, 10 %, 20 %, 30 %, and 40 %. Making brick with the combination of soil, sand, water and the combination of aggregate of blass bottle waste, in the drying process within 1-2 days then burning in the  oven with temperature 900 oC for 3,5 hours. And then the brick is tested 3 parameters are the pressure, the absorptive and the density. Based on the test result it was gotten each of the parametre tests are the minimum value of the pressure is 223,41 kg/cm2 and the maximum is 253,37 kg/cm2 (based ont the class category 200 to 250 based on  SII-0021-1978); the water absorptive value was gotten in minimum is  9,38 %  and the  maximum is 19,05 % (based on  standard SII 15–2094–2000) and the dencity value is 1,48 - 1,64 gr/cm3 (based on  standard).

Abstract

The research of the Saddang fault pattern based on the level of seismicity and focal mechanism (a case study in January 2010- July 2020) aims to determine the level of seismicity in the Saddang fault area and the Saddang fault focal mechanism in the 2010-2020 earthquake. The data which were used were secondary data from the BMKG catalog from January 2010 - July 2020. The coordinating limit is 118.50 ° East Longitude 120.60 ° East Longitude and (-2.60 ° South Latitude) - (-5.70 ° South Latitude) there were 1425 earthquakes. This research used ArcGis application to measure seismicity distribution map and seiscomp3 to measure focal mechanism. Furthermore, the focal mechanism divides the region into three regions. The results which obtained from the seismicity map obtained a high level of seismicity with a shallow depth. Which was caused by the lack of factors from the active Saddang fault and Sulawesi who had four plate junctions. The results of the focal mechanism in each region had the whole type of shear fault or horizontal. Keywords: Earthquake, geology software ArcGis, software seisco

Abstract

Energy is one of the most hot issue today.  Energy consumption has increasing every year around the world but the sources  not increasing significanly.  Most of the energy source come from coal and oil with decrease every year. However oil and charcoal tends to be distinctive near future since it not renewable. Besides, it is polluting, environmentally harmful and rather expensive. As consequence  it is important to explore another renewable energy resources. One good example is solar energy, with using sel phovoltaics technology. Photovoltaics technology have been presented with higher efficiency and low cost in production such as perovskite solar cell.
