Abstract

Technology can be used as a preventive measure to avoid theft. One technology that can interfere and even make the perpetrator cancel the robbery is an alarm. With the sound of the alarm, the thief can be surprised and will immediately save himself because he is worried about being caught. Until now, various alarm technologies have been studied, from simple to complex. There are also many sensors used as triggers for alarm activation. This study created a simple anti-break alarm that is not easily turned off using a magnetic switch and relay. Several parameters are measured to determine the performance of the input and output of the alarm such as voltage and current, then a consistency test is carried out from the alarm that was created. The results obtained were that the alarm functioned properly. The alarm can sound when the door is opened then continues to sound and does not break when the door is closed again. The alarm also works consistently after 100 tests.

Abstract

The cutting quality of a lathe is influenced by various cutting parameters. Spindle speed is the main parameter that influences the level of surface roughness and tool wear. The research aims to understand the impact of using a VNMG 160408-MA type insert tool in cutting AISI 4340 steel on surface roughness and tool wear values. The spindle speeds used are 190 rpm, 300 rpm, 460 rpm, 755 rpm, 1,255 rpm, feed rate 0.209 mm/rev, and cutting depth 0.5 mm. Experimental methods were used in the research. The research results showed that variations in spindle speed had a significant effect on surface roughness, tool wear and cutting temperature as evidenced by the P-Value < 0.05. At a value at a spindle speed of 190 rpm, the surface roughness value was 6.195 μm, tool wear was 0.002 grams and tool temperature was 48.178 °C. The spindle speed value of 1,255 rpm measured a surface roughness value of 1.971 μm, tool wear of 0.053 grams, and tool temperature of 90.389 °C.

Abstract

The increasingly widespread use of structural steel in everyday life, despite its tendency to undergo corrosion, results in financial losses and poses safety risks if damage occurs. This study aims to analyze the effects of nitrocarburizing on the hardness, corrosion rate, microstructure, and composition of low-carbon materials SS400 and ASTM A36. The research method used is experimental. Data analysis techniques were obtained by comparing the results of each test. The nitrocarburizing test results showed differences in hardness values and corrosion rates for SS400 and ASTM A36. The SS400 test results at 350°C were 221.04 VHN and 0.26993 mpy, at 400°C were 278.85 VHN and 0.30959 mpy, and at 450°C were 440.39 VHN and 1.4548 mpy.

Abstract

Adhesives are an alternative to many joints because they are cost-effective, corrosion-resistant, neat, and strong for low-load construction such as window/door frames. Aluminum material is rigid but deformable, making it prone to cracks in the adhesive joint area. The addition of sikaflex was chosen because it is a low stiffness and elastic adhesive that bonds well to metals, ceramics, and plastics. The purpose of this research is to analyze the effect of adding sikaflex to epoxy adhesives with a percentage of 15%, 25%, and 35% on the shear tensile strength of aluminum single lap joints. The surface of the adherend was given a roughness treatment by sandblasting method to improve the mechanical interlocking between the adherend and the adhesive.  The sandblasting roughness test before treatment was 0.50 µm to 2.90 µm. Shear tensile test results of sandblasted specimens increased in all mixed adhesive variations. The highest strength mixed adhesive with composition 15%SF: 85%EP. Visual observation showed mixed failure mode between cohesive failure and adhesive failure occurred in all mixed adhesive variations.

Abstract

The thermal spray aluminum (TSA) coating method is used to prevent damage to the metal surface and improve the quality of the metal surface by bonding the coating. The coating standard has a minimum thickness of 80-100 µm. According to AWS C2.23M/C2.23, NACE N0.12, SSPC CS-23, coatings submerged in seawater will experience a decrease in coating thickness of 20 µm. This study aims to examine the effect of air pressure in the thermal spray coating process on AISI 1020 steel on the bond strength of the coating to the base metal. The research was conducted using air pressure variations of 3 Bar, 3.5 Bar, and 4 Bar. Furthermore, dry film thickness, pull off adhesive, and bending tests were conducted. The dry film thickness test results show that the higher the air pressure, the coating thickness increases. The results of the pull off adhesive test show that the higher the air pressure the bonding strength of the coating also increases. The bending test results show results that are in accordance with standard practice item No.21100 where there are no cracks and small cracks are still allowed.

Abstract

This research aims to analyze the performance of oil-water separation using a hydrocyclone-bubble generator. The bubble generator used was an ejector type to make it easier to suck in atmospheric air. The research was carried out by injecting an oil-water mixture through a bubble generator before entering the hydrocyclone system. The air flow injected into the bubble generator was varied from 0.1-1.5 lpm. From experimental studies, it was found that as the air flow increased, the split ratio also increased. The pressure drop at the overflow increases gently while the underflow pressure drop increases significantly along with increasing input air flow. The greater the input air flow, the more significant the difference in underflow and overflow pressure drop. It has implications for a larger pressure drop ratio. The greater the air flow, the greater the overflow efficiency decreases, and the underflow efficiency increases. The highest efficiency in overflow is 87.77%.

Abstract

Casting is the process of manufacturing molten metal with a mold to produce a shape close to the original shape. The commonly used molding sand is mountain sand, river sand and silica sand. This research aims to analyze defects and tensile test results of castings with various types of sand (beach sand and silica sand) and types of aluminum (ADC 12 aluminum and aluminum from waste cans). The casting method used is traditional sand blasting. The results show defects in the form of surface hardness, rat tails, shrinkage cavities, and pinholes. The tensile test showed that the highest Ultimate Tensile Strength (UTS) value was obtained from a mixture of Al ADC 12 with beach sand with an average UTS value of 172.44 MPa.

Abstract

Natural fiber composites are increasingly being developed to substitute less environmentally friendly materials such as metal and fiberglass. Petung bamboo has the potential to be a substitute for glass fiber in polymer composite reinforcement because it has good fiber quality. This research aims to determine the effect of random fiber arrangement with variations in fiber length on mechanical strength. The composite was made using the hand lay-up method with fiber length variations of 5 mm, 10 mm, 15 mm, and 20 mm. The volume fraction of petung bamboo fiber is 30% soaked in 5% NaOH for 2 hours. The research results show that specimen C has the highest tensile strength and elastic modulus values ​​of 1.25 Kgf/mm^2 and 1.93 Kgf/mm^2. In contrast, specimen A has the lowest tensile strength and elastic modulus values ​​of 0.76 Kgf/mm ^2 and 1.14 Kgf/mm^2. The rich, void, and fiber pull-out matrix causes the mechanical strength of the composite to be less than optimal. The effect of adding petung bamboo fiber in the composite can increase the mechanical strength as the fiber length increases.
