Abstract

The Umbi teki skin peeling machine is a machine used to assist in the process of making chips. Umbi teki, which will be processed into chips, will go through several processing processes, such as soaking the material with clean water first and then peeling the fiber and skin until it is clean, then roasting until the texture of the seeds starts to soften and then pounded using a hammer, after which it is dried in the sun until it is scorched. One of these production processes is carried out using this peeling machine to peel the skin of the Umbi teki. Factors affecting peeling include engine rotation speed (rpm), while some researchers state that the best average rotation speed on a peeling machine is 250-500 rpm. This study aims to determine the effect of engine rotation speed on stripping results and find the best rotation speed on an Umbi teki peeling machine with a load of 121 grams/minute. The method used in this research is an experimental study conducted with ten rotation speed variations. Data were analyzed using ANOVA to determine the best variation treatment. Results show that using engine rotation speed variables affects the average difference in skin stripping. The best engine rotation speed of 626 rpm produces the best percentage of stripping results, with a value for TB (Well Peeled) and TS (Not Perfectly Peeled) being 87.3%  and 9.3%, respectively.

Abstract

Hand disabilities can limit individuals from achieving the full range of finger movements seen in typical human hands, rendering some unable to grasp objects effectively. In response, this project introduces a portable 5 Degree of Freedom (DOF) robotic hand. It serves to amplify the limited flexion range of an impaired hand, expanding it to match the completely normal range of motion found in a robotic hand. This innovative solution is designed to attach to the palm of the impaired hand and is controlled by a glove equipped with five flex sensors. These sensors precisely measure the angles of finger bends and translate them into appropriate servo motor angles, facilitating enhanced dexterity for the user.

Abstract

The combustion system in the CFB boiler had a high complexity, in order to identify and understand the combustion process that occurs in the CFB boiler, CFD analysis was applied. This study was conducted to analyze the combustion and gas emissions produced in a CFB boiler with several variations of coal mixture. Coal particles injected into the furnace were modeled with DPM, specifically the Euler-Lagrange approach. The coal used came from two coal mining industries and mixed with the percentages of 20% : 80%, 30% : 70% and 40% : 60%. The amounts and conditions of combustion air and coal had been determined. The simulation process in the CFB boiler was carried out at a maximum load (110 MWe) without involving bed material. The results showed that the energy and combustion temperature produced in the mixture of 20% : 80% reached the highest value, the mixture of 40% : 60% produced the highest concentration of H2O and produced the lowest concentrations of CO2, O2, NO and SO2. On the other hand, the distribution of pressure and gas velocity had relatively the same value in each mixture. This could be caused by the characteristics of coal mixture, the amount of air and coal injected, and the absence of bed material.

Abstract

In this research, molecular dynamics (MD) simulations were performed to model the effects of copper content on aluminum properties. Copper has a low solubility in aluminum. Therefore, the main purpose of this research is to study the influence of copper content (Cu) on the mechanical properties of aluminum. Modeling and simulation of nano indentation and uniaxial tension tests were carried out to observe the mechanical properties under the conditions of copper content starting from 0.5 up to 10wt% at 300oK. The interactions between the atoms of aluminum and copper were modeled using Embedded Atom Method (EAM) potentials. The calculation showed that a higher amount of copper increased the tensile strength of aluminum, and in this research,10wt% copper gave the highest tensile strength. But when it comes to the nano indentation test to determine hardness value, it showed that 1wt% copper gave the highest hardness, it assumes that this is related to localization of nano indentation test position optimum formation of intermetallic aluminum-copper, Al2Cu on a certain area.

Abstract

The existence of lightning as atmospheric electricity should be thoroughly reviewed concerning the process of going over a subject again in a study that can explain its existence. A review in the form of presenting the State-of-the-Art (SotA) of the existence of lightning with objectives is examined, which includes the description of (i) the forming Cumulonimbus (Cb) clouds and lightning generation; (ii) the principles of electromagnetic field measurement; and (iii) the lightning strike detection systems and an example of calculating the efficiency value. A researcher's algorithm for carrying out the study takes the shape of achievement and adherence to explain in the form of literature reviews. Therefore, a flowchart based on the form algorithm can be created. The results and discussion of three main things related to explaining the existence of lightning as atmospheric electricity include forming Cb cloud and lightning generation, electromagnetic field measurement principles, and lightning strike detection systems, which are equipped with an example of calculating the efficiency value. Based on the discussion of three main things, it can be concluded that explanations of many kinds of literature reviewed can elaborate an understanding of the existence of lightning.

Abstract

Ethanol is beneficial for the sterilization process and increases the rate of photosynthesis. Measurement of ethanol concentration is necessary because ethanol in high concentrations can cause several health problems, such as eye irritation, coughing, lacerations, and ineffective plant sterilization processes. Therefore, a sensor-based measurement system is needed to measure the total gas concentration in liquid organic fertilizer. This research aims to characterize the MQ-8 sensor and analyze the ethanol concentration for the fermentation process. The results of this study indicate that the MQ-8 sensor can work well in measuring the concentration of a single ethanol compound with an accuracy of 91%. The total concentration of ethanol gas in each sample liquid organic fertilizer is measured between 216 ppm to 1583 ppm, depending on the fermented plant.

Abstract

A safety instrumented system (SIS) is specifically designed to protect personnel, pieces of equipment, and the environment by reducing the likelihood or severity of the impact of identified emergency events. This review has five objectives, i.e., (i) to find the layers of protection, (ii) to figure out and implement the SIS through life cycle step design, (iii) to find the Safety Integrity Level (SIL), (iv) to find the Safety Requirement Specification (SRS), and (v) to figure out and think about the SIS design that will be used. The study's methods are algorithms that a researcher uses to carry out research in stages of achievement and accordance with research objectives. Referring to the review proposed, five results have been achieved, which are guided by the process stages. The SIS design has been implemented and can be used as a reference for understanding the basic concepts and instrumentation of process control systems. The second is figuring out and implementing the SIS, which is an essential stage in the life-cycle step process. The third, the SIL determination, can be done using qualitative or quantitative methods that involve evaluating two risk components, e.g., probability and severity, and lies in the risk levels and the weighting structure. Furthermore, a matrix shows many of the factors that are used to determine the SIL levels. Fourth, the SRS consists of two parts, i.e., requirement specification of the functional and the integrity. Fifth, one of the considerations in designing the SIS is the separation between the SIS and the BPCS, thereby reducing the possibility of both systems failing simultaneously. Finally, the consequences range from minor injury to high death, and the main conclusion in this article is that the concept system will make it easier to find references or get predictions for determining instrumentations and creating a process control system.

Abstract

The raw salt should be reduced the size to convert it into consumption salt. Salt crushing machine generally was designed to reduce salt grain size using rollers for crushing. The small-capacity salt-crushing machine should be designed to meet the needs of small businesses. This study aims to design a salt-crushing machine in a small capacity with a proper power transmission system that will be applied to a roller-type salt crusher. The transmission system is designed to upgrade the performance of roller-type salt crushers through V-belt and pulley transmission mechanisms and obtain the appropriate size or type of V-belt and pulley based on the capacity of the drive motor. The results show power required to crush salt by this system is 299.46 W. The motor used is a single-phase AC motor that has a power size of 1/2 HP, and the corresponding v belt is type A with a size of 51 inches, the rpm needed is 360 rpm, and the distance between rollers is 0,7 mm. Then the pulley needed is with a ratio of 1: 4. The pulleys used are type A1 which has a diameter of 3 inches and 12 inches. The average salt weight loss after the crushing process was 14.27%.
