Abstract

The purpose of this study was to determine the effect of variations in the angle and distance of sandblasting on paint coating quality and corrosion properties of low carbon steel. The success of a coating is highly dependent on surface roughness, so sandblasting is needed to clean and create a surface roughness profile with the aim that the paint can coat the surface perfectly. The test method used in this research is the pull off test method for testing the adhesive strength of paint and open circuit potential (OCP) for testing the corrosion potential. The sandblasting variations used are angles of 45⁰, 60⁰, 75⁰ and nozzle distances of 15 cm, 35 and 50 cm. The tests carried out were roughness, paint thickness, paint adhesive strength and corrosion potential. From the test results it can be concluded that the greater the angle and the closer the sandblasting nozzle distance, the greater the surface roughness. The greater surface roughness affects the paint layer to be thicker and has a high paint adhesion strength, resulting in a smaller corrosion potential. In this study, the highest test results were obtained at an angle of 75⁰ and a distance of 15 cm with a surface roughness value of 5.981 µm, a paint thickness of 115 µm, a paint adhesive strength of 7.28 MPa and an initial corrosion potential position of -0.101 V then a final position of -0.063 V.

Abstract

The purpose of this study was to determine the high temperature erosion rate of the NiCr coating on ASME SA 210 C steel using the combustion oxy fuel thermal spray method. In Circulating Fluidized Bed (CFB) boiler, there is circulation of fly ash, silica sand and air in a high temperature environment which causes erosion. High temperature erosion can be minimized by using Ni-Cr alloy coating sing the combustion oxy fuel thermal spray method. NiCr alloy is proved a able to provider a metal alloy layer composition that can withstand temperatures of 600°C with a fly ash impact speed of 200m/s. The metal alloy compositions that have been studied are NiCr, NiCrCo, NiCrWc, NiCrWcCo, and NiCrCoMo. The results of this study indicates that metal alloys are generally atteche to the substrate and withstand at a high temperatures (600°C). The highest hardness provide by NiCrWcCo alloy which is 177.46 HV. The lowest hardness is found in the composition of the NiCrCo alloy (161.71 HV). The lowest high temperature erosion rate was found in the NiCrWcCo alloy, which was -0.00481 gram/minute. This low erosion rate because the NiCrWcCo alloy produces a good weeting effect for metal alloys and has a high hardness value.

Abstract

The corrosive coastal environment will result in a high corrosion rate for any equipment installed there. This is due to the constant exposure to saltwater, high humidity levels, and strong winds. Therefore, it is crucial to use corrosion-resistant materials and regularly maintain the equipment to ensure its longevity in such an environment. One method to reduce the rate of corrosion is to pay close attention to the manufacturing parameters of these components, one of which is the face milling process. The aim of this study is investigating the effect of face milling process with different dept of cut using minimum quantity lubrication method with corn oil as a renewable vegetable cutting fluid. In this study AISI 316L stainless steel was face milled using HAAS VF-2 CNC machine. The depth of cut is varied between 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, and 0.6 mm. The results demonstrated that the greater the depth of cut, the greater the surface roughness value that will be generated. It is resulting in increment in the corrosion rate value.

Abstract

Galvalum has become an inevitable part of Darul Muttaqin Batu Islamic Boarding School construction. The ease of access, affordability, and simplicity of installation have led to most buildings within the boarding school using galvalume. However, professional galvalume workers are still employed when it comes to the structure and construction at the boarding school. As a result, the boarding school has to incur high costs to construct or create equipment made from galvalume. In addition to the above-mentioned issues, the students are a valuable human resource that can be utilized to create equipment from galvalume. However, because the students are not yet familiar with how to cut, assemble, and create kit from galvalume materials, training is essential to provide them with additional skills alongside their religious studies at the boarding school. This endeavor involves the contribution of equipment for galvalume material manufacturing and training on assembling galvalume materials according to the boarding school's needs. Through these activities, it is hoped that knowledge will be transferred from the university/instructor to the students. Consequently, this not only equips the boarding school but primarily provides the students with skills so that when they graduate from the boarding school, they have the skills to lead a decent and self-sufficient life.

Abstract

One of the important contributions from the academic community of Brawijaya University is the empowerment of students in the boarding school setting. A range of empowerment programs have been adopted, encompassing the enhancement of traditional beverage production tools and workshop tools, as well as the introduction of handicraft innovations to augment income. The economy of the students and members of the Darul Mutaqin Islamic boarding school in Dau Village, Batu City, primarily relies on donations, supplemented by revenue generated from the sale of herbal goods. The school is strategically located next to rice fields, which offer ample natural resources. Food self-sufficiency can be achieved by utilizing animal husbandry techniques that involve feeding animals with nutritious green feed derived from agricultural waste, such as water hyacinth and maize stalks. This approach holds significant promise. Presently, the livestock industry at Darul Mutaqin Islamic Boarding School, namely in poultry farming, remains underdeveloped despite the ample availability of natural resources. Poultry farming, a generally manageable approach, might suffer a decrease in economic profitability if not adequately planned. The implementation of suitable technology via the Doktor Mengabdi initiative is anticipated to enhance students' proficiency in animal husbandry, augment livestock yield, and uphold environmental well-being. Darul Mutaqin's future goals include attaining financial self-sufficiency. This effort offers solutions by implementing a cutting-edge pilot project for a contemporary livestock system that integrates diverse mechanization and automation technology. The purpose of these suitable technologies is to generate sustainable poultry products, hence benefiting the pesantren community.

Abstract

The growing demand for advanced coatings in industries such as aerospace and automotive necessitates materials with superior hardness, wear resistance, and thermal stability. Despite advancements in ternary coatings, research on binary Titanium Nitride (TiN) coatings remains limited, particularly in optimizing deposition parameters for lightweight aluminum substrates. This study aims to investigate the effects of sputtering parameters, specifically Ar:N₂ gas ratios and deposition durations, on the mechanical properties of TiN coatings on Al 6011 substrates. The optimized conditions (70Ar:30N₂ gas ratio and 60-minute deposition) yielded a 165% increase in surface hardness (88.92 HV) and a 54% reduction in wear rate compared to untreated samples. XRD and SEM analyses confirmed the dense microstructure and strong (200) phase orientation contributing to these enhancements. This research highlights a cost-effective and scalable approach to improving the performance of aluminum alloys, bridging the gap between fundamental studies and industrial applications.

Abstract

A coating is widely applied to protect base material during contact with surrounding. One important application in engineering is to protect a boat hull. The coating is applied to boat hull to prevent a decrease of mechanical properties of base materials particularly with corrosive seawater. Composite coating is applied since the composite coating provides better protection compared to paint coating. Additionally, sandblasting prior to composite coating is worked out to improve the mechanical properties of the coating. This work investigated the influence of the projection angle of the sandblasting process on the shear strength of the coated surface. The projection angle of sandblasting was varied from 30 to 90 °. The result shows that a higher projection angle decreases the strain strength of the coating surface. The experiment work showed that the shear strength of 30°, 45 °, 60 °, and 90°projection angle are 1.02, 0.66, 0.38, and 0.24 MPa, respectively.

Abstract

The purpose of this study was to determine the effect of immersion time of NaOH at a temperature of 60-70 ℃ in wulung bamboo fibers on the tensile strength of the epoxy matrix composites. Wulung bamboo fibers (Gigantichloa Atroviolacea) have the potential to be used as reinforced in composites because they have high strength and are widely grown in Indonesia. In this study, bamboo wulung fiber reinforcement was used without treatment and with variations, soaking time 30 minutes, 60 minutes, and 90 minutes in 6% NaOH solution with a temperature of 60-70 ℃. The composite manufacturing method used was vacuum assisted resin infusion and the standard composite specimen used as a tensile test was ASTM D638-01. The results showed that the longer the immersion time resulted in a rougher topography of the fiber surface which caused the composite tensile strength to increase due to the better mechanical interlocking between the fibers and the epoxy resin matrix. The wettability results on the fibers also show that the wetness between the fibers and the epoxy resin matrix is getting better, which is shown from the droplet contact angle on the resulting fibers. The highest composite tensile strength was obtained at 90 minutes immersion time of 169.765 MPa followed by immersion time of 60 minutes of 123.2 MPa, immersion time of 5 minutes of 81.7 MPa and without treatment of 71.6 MPa. Based on the results of the macro photo shows that the treatment given will reduce the failure of the pull out and debonding defects on the composite fracture.
