Abstract

A research has been done on the mechanical bricking test with the addition of bagasse ash. In this study, the tested bricks tested were compressive and flexural strength. The purpose of this study was to determine the effect of adding bagasse ash to the mechanical properties of the concrete brick. The percentage variation of bagasse ash, cement, and sand are 0%:30%:70%, 5%:25%:70%, 10%:20%:70%, 15%:15%:70%, 20%:10%:70% with Water Cement Ratio of 0.5 in all variations. The addition of bagasse ash as a substitute for cement significantly affected the characteristics of the concrete brick. With the addition of bagasse ash in a mixture of 5-20% causes the compressive strength to decrease. While the flexural strength has increased in the variation of the mixture of 5-10% and has decreased in the variation of the mixture of 15-20%. The most optimal composition of mixing bagasse ash, cement, and sand is at 5% mixture variation for compressive strength and flexural strength testing because it meets SNI 03-0348-1989 standards. Whereas the other mixed variations are not optimal. Keywords : Bagasse ash, Compressive Strength, and Flexural Strength.

Abstract

Biobattery research has been carried out using cassava leaves (Manihot Utilissima) as a substitute for carbon in some 1.5 volt batteries. And tested the voltage with the results of sample A: 1.53 volts; B: 1.54 volts; C: 1.55 volts; and D: 1.58 volts. Then the electric current was also tested with the values obtained in sample A: 0.08 mA; B: 0.10 mA; C: 0.13 mA; and D: 0.19 mA. If the carbon mass in the biobattery gets higher, the value of the voltage and electric current test results changes with the higher in each sample. By performing the performance on the cassava leaf biobattery, it is able to turn on a 2.5 watt LED lamp with 3 batteries. Keywords: Current, cassava leaves, and voltage

Abstract

The kitchen is one of the places most concerned by every community because the biggest fire potential in the house lies in the kitchen, the source of fire that often causes fires in the kitchen is a stove and gas. Therefore we need a design of a kitchen security system based on the ATmega32 microcontroller using flame sensors, MQ-2 and MQ-6. This study aims to produce a performance tool that will detect any movement of fire, gas, and smoke using an Early Warning System. The warning in the form of an alarm sounds, the fan turns, and the door opens automatically. Sensor detection is designed with 4 conditions namely Normal, Caution, Alert and Danger. The results of testing using the Flame sensor found a wave range from 22 nm to 1022 nm from normal to hazardous conditions, the MQ-2 found the results of testing from the ADC (Analog Digital Converter) with concentrations from 0 ppm to 130 ppm from normal to hazardous conditions, and the MQ-6 test results were obtained from the ADC (Analog Digital Converter) with concentrations from 0 ppm to 520 ppm from normal to dangerous conditions. Keywords : Kitchen, ATmega32, Flame sensor, MQ-2, and MQ-6.

Abstract

Research has been carried out on "The effect of increasing the volume of the solution of star fruit juice and key orange juice on the pH value, electrical properties and changes in electrode mass". This study aims to determine the effect of volume variations of starfruit juice and key oranges (0%:100%, 25%:75%, 50%:50%, 75%:25% and 100%:0%) on the pH value, voltage, current, and electric power, to determine the decrease in voltage and electric current due to the loading of the red LED lamp for 1 hour and to determine the change in the mass of the Cu-Zn electrode for 1 hour. This research was carried out with the working principle of a voltaic cell using a pair of Cu-Zn electrodes as anode and cathode connected in series. The measurement results obtained that the best sample variation is in the 100% variation of starfruit juice with a total volume of 300 ml resulting in the values of pH, voltage, current, and electric power of (2.2; 1.73 V; 1.05 mA, respectively). ; and 1.81 mW), while for the lowest sample variation, there is a variation of 100% key orange juice with a volume of 300 ml producing the values of pH, voltage, current, and electric power, respectively (2.8; 1.64 V; 0, 99 mA and 1.62 mW). The more variations in the volume of the key orange juice, the better the voltage, current and electric power. As for the test results, the loading of the red LED lights causes a decrease in voltage and electric current for 1 hour, so the longer the loading time, the dimmer the lights. Furthermore, for 1 hour the voltaic cell reaction took place, resulting in a change in the mass of the Cu-Zn electrode where the mass of the Cu electrode increased and Zn decreased. Keywords: Starfruit, key oranges, pH, electricity

Abstract

A research has been conducted on the comparison of the value of burnt shrinkage and porosity of bricks by adding a mixture of coconut husk ash and rice husk ash. The purpose of this study is to determine the effect of variations in the addition of coconut husk ash and rice husk to the value of burnt shrinkage and porosity of bricks. Porosity testing was carried out due to the addition of a mixture of coir ash and rice husk to produce porous bricks. Variations in the percentage of clay with a mixture (coconut husk ash and rice husk ash) include 100%:0%, 95%:5%, 90%:10%, 85%:15% and 80%:20%. The results obtained for the value of burnt shrinkage from the addition of rice husk ash in brick making results are smaller than the addition of coconut coir ash. The results of the shrinkage value of the addition of coconut coir ash and rice husk already meet the SNI 15-2094-2000 standards that is <15%. However, the porosity value from the addition of coconut husk ash and rice husk ash does not meet the standards required in SNI 15-2094-2000 because> 20%. With large porosity values exceeding SNI 15-2094-2000 standards, the suggested bricks are used as an inner wall and cannot be used as a face wall. Keywords: burnt shrinkage, coconut husk ash, porosity, and rice husk ash.
