Abstract

The cooling tower has a working principle for cool the water fluid forcibly using a fan or blower. This Research aims to determine the effect of the number of filler bulkheads and the angle of openingvalve to the cooling tower work efficiency. This research uses type induced draft cooling tower with flow opposite the tool size laboratory scale. Research variables include 3 variations in the number of bulkheads (2 bulkheads, 3 bulkhead and 4 bulkheads) and 3 variations of valve opening angles (30, 45 and 60). Result measurements in the form of water discharge data, water temperature data, air temperature data, temperature data environment (Twb) and temperature difference data. Water discharge data is measured with a flow meter and stop watch. Temperature data measured with a Digital Thermometer. Data were collected 5 times repetition of each data. The measurement results are taken the average value for measures the discharge, temperature, heat transfer rate and efficiency of the cooling tower. The results showed that the number of bulkheads and the angle of the opening valve has an effect on the working efficiency of Cooling Tower which is getting more the greater the number of bulkheads the greater the cooling tower work efficiency and vice versa but the greater the valve opening angle the smaller the cooling tower efficiency.The maximum efficiency obtained from this study is at the number of bulkheads 4 and the valve opening angle of 30 with a Cooling Tower efficiency value of 78.40%.

Abstract

Optimization of the cassava chopper machine can be done to minimize the consumption of electrical power required by the driving motor by changing the configuration of blade angle with rotation. This research was conducted experimentally by changing the angle of the knife on the chopper machine with an angle of 45, 60, and 90o. The rotation of the chopper shaft was varied by 150, 200, 250 rpm. Data was collected during the process by measuring the voltage and electric current on the motor using a digital avometer. In addition, video data and photos were collected using the camera. The results showed that the blade angle and rotation had an effect on the performance of the cassava chopper machine.

Abstract

The effective mixing can be seen from the length of the stretching, the number of folding and the consumption of electric power required in the process. A suitable type of stirrer, a varying number of blades, can enrich the flow pattern created. This study aims to determine the effect of the number of mixing blades on the mixing pattern and the consumption of electric power in the vertical mixer. the number of blades varied (number of blades 4,6,8 pieces). The test material is given a dye, so that we can see the mixing pattern that occurs for electrical power consumption can be calculated with a digital multimeter. From the results of this study, we will be able to measure the length of the stretching and the number of folding produced in rounds 1-4. And will be compared with the required electric power consumption. The results showed that the more mixing blades used, the less power consumption required. The more blades used, the longer the stretching results. The more mixing blades used, the more folding can be produced..Keywords: mixing, stretching, folding, number of blades

Abstract

Sieving is the separation of various mixtures of solid particles that have various sizes of materials using a sieve. The sieving process is also used as a cleaning tool, separating contaminants with different sizes from the raw material. This study aims to determine the effect of the vibrating screen angle on the sieve's performance. The research was conducted by experiment using a flat type vibrating sieve. The angle of the sieve was varied by 0, 5o, 10oand 15o. The vibratory motion of the sieve was varied with the crank method using a rotation of 13.5; 21.3 and 27 rpm. The sieve holes use a screen with mesh sizes number 8, 10 and 12. The sifted sand is 1 kg. Data were collected for the fine and coarse sieve results and the sieving time. The results showed that the angle of the sieve had an effect on the performance of the sieve .
