Abstract

The control system is an engineering discipline that involves mechanisms and algorithms to control the output of a process with the desired results. Modern industries and power plants use control valves as a control system in storage tanks. The control valve is a very important component in this regard as a final element. Therefore, we designed a control valve starting from the sizing control valve, mathematical modeling of the system to programming on Arduino and Visual Basic .NET so that it can be observed and understood directly. After sizing the control valve, it can be seen the type of valve that meets the valve opening standard is Globe valve at 46.8% and Ball valve at 33.0%. In this study, the commonly used PID tuning method is Ziegler Nichols tuning method to test the control system. The PID parameter is obtained through the tuning results in the Matlab simulation using mathematical modeling of the system. Control valve simulation with Matlab produces parameters Kp= 0.5625, Ti= 0.3, and Td= 0.7. While the control level produces a parameter Kp= 1.36, Ti= 3.33. The control level of the storage tank is better to use PI control compared to PID controls which continue to increase water levels. Changes in set point from 1 cm to 20 cm produce a 37-seconds settling time with a maximum overshoot value of 6 cm.

Abstract

The declining petroleum production in Indonesia requires the alternative ofrenewable energy and be more eco- friendly, so it needs more flexible alternative energy. Oneof them is the energy gained from oxyhydrogen gas (Brown Gas). Oxyhydrogen gas can beobtained by breaking down the water molecule (H2O) with the help of electrical energy orcommonly called an electrolisys process. In this study, used oxyhydrogen dry cell generatorstype with 316L stainless steel electrode material consisting of 6 cells with the variation of theKOH catalysts 50, 60, 70, 80, and 90 grams per 1 liter aquadest. The characteristics of theoxyhydrogen generator performance testing are obtained, power consumption, oxyhydrogen gasproduction rate, and oxyhydrogen generator efficiency. From the results of studies that havebeen conducted, it is possible to know that increasing the concentration of KOH catalysts leadsto increased power consumption. The highest electrical energy consumption is 38,94 Watt at theconcentration of the KOH catalyst 90 gr/l and the lowest electrical energy consumption is 21,25Watt at the concentration of the KOH Catalyst 50 gr/l. Then the rate of oxyhydrogen gasproduction is increasing with increasingly high concentrations of KOH catalysts. The highestoxyhydrogen gas production is 9,045e-7 kg/s at the concentration of the 90 gr/l KOH catalystand the lowest oxyhydrogen gas production is 4,522e-7 kg/s at the concentration of the KOHCatalyst 50 gr/L. So the highest oxyhydrogen generator efficiency is 54,76% at the 70 gr/lconcentration of the KOH catalyst.

Abstract

The effect of (CH2)n on the combustion characteristics of organic waste charcoal pelletfuel has been studied visually and experimentally on atmospheric pressure and roomtemperature. Organic waste charcoal particles containing (C, O, Mg, Al, Si, Ca), and plasticbottle oil are formed as polyethelin (CH2)n. Pellet fuel is made from a mixture of polyethelinand organic waste charcoal particles, based on a percentage of the mass ratio (1; 5; 10%). Thecharacteristics of pellet combustion are identified from the time and temperature signal of theflame, by igniting a pellet under the thermocouple junction. The results showed that theincreasing mass of the mixture had a stronger influence on the pellet combustion process,indicated by the faster start-up time with an increased pellet burning rate. The catalyst in theorganic waste charcoal binds hydrogen from (CH2)n, forming the molecular structure (CH2)n tobe weak with a low density, therefore it can quickly evaporate and burn. With the bigger massof the mixture, carbon moles in pellets are increasing. Consequently, the greater the mass ratioof the mixture will form wider energy absorption characteristic, forming an equilibriumstoichiometric reaction by producing an increased rate of combustion energy release. Theincreasing mass of the mixture, helps the generation of activation energy is greater in theburning of organic charcoal waste pellets, as confirmed by the greater absorption of infrared%T energy.
