Authors: Mastang  , Pahmi M A
Published: April 2020

Overall Equipment Effectiveness (OEE) is a production machine performance measurement system. Performance measurement with OEE consists of three main parameters in the production machine, namely Availability (machine availability time), Performance (number of units produced) and Quality (quality produced). Many OEE monitoring modules are on the market. These modules are still very expensive so most companies are still unable to implement OEE into production machines. In this research, a software called OEEMAX which functions for OEE monitoring has been developed to be installed on Raspberry Pi. OEEMAX was built to be able to run on Raspberry and be able to read inputs from sensors. OEEMAX is also able to communicate with all types of Programmable Logic Control (PLC). The advantage of Raspberry Pi is the price of the module which is very cheap and uses open source operating system. OEEMAX has been successfully developed and applied to Raspberry Pi. It is able to read sensors through general purpose input / output (GPIO) and communicate with PLC using RS-232 protocol. In addition, it is also capable to send OEE data to SQL server.

Published: April 2020

Ultrafiltration (UF) membrane was prepared by blending polyvinyl chloride (PVC) with ZnO nanoparticle (ZnO-Np) and acetone as additives, and then used to treat peat water. The influence of PVC and ZnO-Np concentration on membrane morphology and humic substance rejection were studied. The experimental results showed that the increase of PVC and ZnO-Np concentration in the membrane solution enlarged the pore size of the UF membrane. Agglomeration of particles was found when 2 wt.% of ZnO-Np was added into the membrane solution. The addition of 10 wt.% of PVC concentration and 1 wt.% of ZnO-Np resulted in peat water flux above 100 Lm−2h−1and average humic substance removal of 61%. When the concentration of PVC and ZnO-Np was increased to 12 and 2 %wt, the humic substance rejection was decreased to 40%. More irreversible fouling occurred in the UF-PVC membrane that prepared by low PVC and high ZnO-NP concentration, which is indicated by the low value of the FRR.

Authors: Wibisono Y Y , Marella S
Published: April 2020

Decision-making in business location selection is a challenging task for companies because it involves multiple alternatives and criteria. Previous studies have investigated this problem using various approaches, and AHP/ANP-based decision-making approach is the most used one due to its capabilities in dealing with the complex problem. Although numerous studies have adopted AHP/ANP approach in determining the business location, but most of them were conducted in the large-scale enterprises and not in the context of culinary business such as cafe. This study is intended for selecting the best business location alternative in the context of small enterprise of culinary industry. We developed a decision-making model based on theories and experiences of the culinary expert to choose the best café location. A total of five major criteria we identified namely location characteristics, demography, competition, physical features, and cost. Each major criterion consists of elements that range from two to five elements. Because there are relationships among elements, therefore we develop a network model, which depicts the criteria, sub criteria, alternatives, and their interactions. We apply ANP by using expert opinion to analyse the importance of each criterion and the rank of each alternative. The final result displays that the competitor strength is the highest importance for small enterprises in selecting the best business location.

Published: April 2020

Ti-6Al-4V is a material that is mostly used in aerospace. In this industry, especially on stabilizer horizontal structure, minimizing burrs height is important, These structures are assembled and drilled. To be economically viable, it is preferred to minimized or even removed burr during drilling process. Aerospace industry needs to drill component in an operation without reprocessing (disassembled, deburred, and fastened). Burr will lead to distortion of work piece dimension, damage to subsurface, and make difficult to handling and assembling of part. Burr occurs during machining because of inoptimum choice of material, tool, and cutting speed. This research uses experimental method by variating rotational speed and material and type of twist drill to find the optimum choice of the parameter and tool for drilling process of Ti-6Al-4V. The quality of drilling process was measured by the height of burr and wear on the tool. The result shows that the lowest burr is 0,085 mm by using HSS-Co twist drill in 500 rpm of speed. The use of HSS-Ti and HSS-Co in high speed will cause chipping worn. Therefore, it is unsuitable to minimize the burr height.

Published: April 2020

Fishing can be done in various ways, including by utilizing lights as fishing tools. The lights used for fishing tools are varied, ranging from torch lights, pressure paraffin lamp, fluorescent lamps (TL, PL, SL, CFL), mercury, and various types of led. However, light transition between one colors to another often scares the fish, driving them out of catchable area shocked by the color change. One solution to address this problem is by smoothly switching the color of the lamp using Pulse Width Modulation (PWM) system on the microcontroller. The color used are the lamp with basic colors of red, green and blue. With power capacity of 50Watt/12Volt, this lamp is classified as High Power Led (HPL) lamp. The light can be free- adjusted, where each lamp can be turned on by its own light or can also be turned on in combination. It can slowly be switch on from an off position to maximum and also can be dimmed from maximum to off. Thus the intensity of the light can be controlled. The HPL and control sections were created separately. Tools and materials used are consist of push-button, microcontroller, optocoupler, mosfet and Red, Green and Blue HPL, Radio-meter (ILT5000 Research Radiometer), Voltmeter, and Amperemeter. The method used was experimental in both laboratory and field. The result of research is in the form of RGB HPL lamp which can be adjusted through control system, such as adjusment for each lamp, or light combination with smooth color transition. Thus, when this technology is applied as fishing tool in liftnet fishing, the targeted fish would still remain on catchable area.

Authors: Tavio  , Rafani Muhammad , Putu Raka I Gusti , Ratnasari Vita
Published: April 2020

The use of concrete material in construction always requires steel bars as reinforcement, particularly to resist the tensile stresses occurred in concrete. This is because concrete has very low tensile strength. However, the use of reinforcing steel creates another issue, namely its durability against corrosion. This paper discusses the use of GRP reinforcement as a replacement to steel reinforcement particularly when it is used in the aggressive environmental zones. GFRP has the advantage of being a corrosion resistance, it is not like the steel. Different failure mechanisms are also found between steel and GFRP. The steel yields first prior to failure, but not with the GFRP since they remains almost elastic until failure. This is due to the difference between the properties of the steel and GFRP materials, thus this issue leads to the difference in both flexural design procedures. This paper studies the comparison of the theoretical flexural strength design of various codes worldwide as well as several methods for predicting the flexural capacity of beams proposed by various researchers. Various percentages of flexural reinforcement possibly used in beams are discussed and compared. Some of the codes used for comparisons include the FIB Bulletin 40, ECP 208-2005, ACI 440.1R-15, and CSA 806-12.

Authors: Oskirko V O , Zakharov A Z , Solovyev A A , Pavlov A P , Rabotkin S V
Published: April 2020

The paper presents a description of a pulsed power supply of a magnetron sputtering system with a power of 10 kW, which has a wide range of output parameters, such as the amplitude, the frequency, and duration of voltage pulses. High values of the pulse current (up to 100 A) and voltage (up to 1800 V) provide the ability to work at low duty cycle, which in turn allows to increase the value of the ion current on the substrate. It has been experimentally found, that changing the frequency and duration of the pulses can increase the ion current density to the substrate while maintaining the average discharge power.

Published: April 2020

The article presents electron-beam sintering of composite cermets based on aluminum oxide and titanium. An electron beam generated by a forevacuum plasma electron source for sintering was used. The sintering samples were made from fine-grained powders and compressed by uniaxial pressing. It is shown that when heated to 1600 °C, a powder mixture with a ratio of aluminum oxide of 50% (wt.) and 50% titanium (wt.) large pores are formed in the sample. Measurements of the emission spectrum of the beam plasma formed above the surface of the irradiated sample showed the presence of aluminum. This may be due to the evaporation of these components during electron beam irradiation.
