Abstract

AISI 1020 steel is a low carbon steel commonly used for ship hulls. The disadvantage of steel is that it corrodes easily. One way to slow down the rate of corrosion is by coating. Coating or plating is the method most often used to slow down the corrosion rate because it is more effective, easy to apply. This research aims to determine the effect of the number of coatings and the spacing of spray coatings on surface roughness and corrosion rate. Variations used are variations in the amount of coating 1 layer, 2 layers, dan 3 layers, also variations in coating distance of 10 cm, 15 cm, and 20 cm. The method used to calculate the corrosion rate is weight loss. The results showed that the best roughness on the 3-layer with 10 cm specimen was 0.857 μm and the lowest corrosion rate was on the 3-layer with 20 cm specimen with a value of 2.376 mpy. The best distance for coating is not too close and not too far. If the distance is too close, the paint will melt (runs) and the amount of paint that sticks will be too large, so the layer will be too thick and smooth. The coating distance that is too far causes the paint to stick a little and causes the paint to dry before it sticks to the media, so that it becomes thin and rough. The more the number of coatings, the better it inhibits the corrosion rate.

Abstract

Kampung Nambangan Perak is located in Kelurahan Kedung Cowek, Bulak District, Surabaya, East Java. The majority of Nambangan residents work as fishermen. The Nambangan community is still unfamiliar with the use of alternative energy such as solar cells to replace fuel oil. The road access of village environment was only illuminated independently by installed map of people’s residents. The dim road conditions can cause a sense of alertness to residents and road users who spent the night. In addition, the installation of lamps with greater power can burden the economy of residents due to rising electricity prices. Based on field observations and direct interviews with local residents, there were three focuses aspects of this community service program, namely the introduction of alternative energy to residents, installation and guidance of lamp maintenance equipped with solar panels. Along with the implementation of guidance and education program for the Nambangan community, it is hoped that the residents will understand and feel familiar with the availability of alternative energy. The residents are also expected to be able to apply the use of alternative energy in their daily life. In addition, residents are expected to be able to carry out the process of assembling and maintaining alternative energy sources, especially solar panels.

Abstract

Pengelasan logam tidak sejenis banyak diaplikasikan dengan tujuan memadukan beberapa sifat untuk saling melengkapi kekurangan masing-masing jenis logam. Kombinasi ini mampu memberikan peningkatan sifat mekanik dan mengurangi biaya. Oleh karena itu, pengelasan ST 42 dan AISI 304 dilakukan guna mendapatkan peningkatan sifat mekanik melalui kekuatan tarik, lalu didukung dengan foto makro untuk mengetahui lebar HAZ. Variasi posisi pengelasan 1G, 2G, 3G dengan menggunakan diameter elektroda 2 mm, 2,6 mm, dan 3,2 mm digunakan sebagai parameter yang diamati untuk mengetahui kekuatan tarik dan struktur makro yang diperoleh. Dari hasil penelitian didapatkan kekuatan tarik tertinggi menggunakan posisi pengelasan 2G diameter elektroda 3,2 mm sebesar 391,92 N/mm2, sedangkan kekuatan tarik terendah terjadi pada posisi pengelasan 3G diameter elektroda 2 mm sebesar 230,83 N/mm2. Sedangkan, hasil pengamatan struktur makro, HAZ terbesar terjadi pada posisi pengelasan 3G dengan diameter elektroda 3,2 mm dengan nilai 0,58 mm, serta nilai HAZ terkecil adalah 0,43 mm dengan posisi pengelasan 3G menggunakan diameter elektroda 2 mm. Hal ini menyatakan bahwa perbedaan diameter elektroda sangat mempengaruhi kekuatan tarik sambungan las, perbedaan hasil pengelasan ini disebabkan karena jumlah fluks pada elektroda.

Abstract

Tungsten Inert Gas (TIG) welding is a welding technique using an electric arc between a non-consumable tungsten electrode and a shielding gas for the heat formation. This research aims to determine the comparison of the macro structure and hardness (Vickers) of 304 stainless steel in TIG welding with spiral, zig-zag and triangular electrode movements, as well as the welding current variatons of 60, 80, and 100 A. The results show that the welding current and movement affect the hardness and HAZ width of the welded 304 stainless steel using TIG welding process. The greater current leads to higher HAZ width and hardness. Furthermore, the spiral movement provides higher hardness due to its fast movement in welding which leads a faster cooling as well. The highest HAZ width reaches the value of 2.05 mm using the 100 A welding current and triangle movement. Meanwhile, the highest hardness is obtained in the value of 450.5 kgf/mm2 in the same current and movement.

Abstract

Residents who work as fishermen in Kalisari tether their boats by the river close to their settlements. To maintain the safety of the boat, residents need adequate lighting around the riverbanks. However, currently, the area used as a boat mooring area does not yet have sufficient lighting. Residents set up guard posts around the boat mooring area to maintain the boat's safety and gather when an association meeting is held. The boat mooring area is also an area for children to play on the riverbank. The installation of lighting is an essential requirement for the community to make monitoring the area around the mooring area easier. The installation of solar-powered lighting is carried out to solve this problem. In this activity, the service team also provided education on solar energy for Kalisari residents. Residents were also given training in the assembly and maintenance of installed solar panels. Service activities carried out in the fishing village of Kalisari received a positive response from the community. This can be seen from the enthusiasm of the community in attending the socialization activities. The installation of lamps equipped with solar panels received positive responses from residents, marked by the community's enthusiasm.

Abstract

Epoxy-based composites are widely used in various applications due to their excellent mechanical properties and durability, but their performance under prolonged UV exposure remains a critical concern. This study examines the impact of UV exposure on the physical, chemical, and mechanical properties of epoxy-silica microballoon composites over curing periods of 0, 200, and 400 hours. Results indicate that UV treatment increased the density from 1.0073 g/cm³ to 1.0129 g/cm³. SEM images showed a reduction in fragmentation of epoxy microballoons, indicating stronger bonding. EDX results revealed some changes in elemental composition, with a notable decrease in the percentage of sodium from 0.81 wt.% to 0.18 wt.% and silicon from 7.16 wt.% to 0.12 wt.%. FTIR analysis identified a new hydrogen bond formations at 3350 cm⁻¹. Mechanical testing showed that UV treatment significantly increased the flexural stress from 36.83 MPa to 49.98 MPa. Additionally, hardness (Shore D) increased from 78.4 to 80.2 Shore D. These findings highlighted the significant effects of UV exposure on the structural integrity and bonding mechanisms of the composites, offering valuable insights for their use in UV-prone environments.

Abstract

Medium carbon steel is a widely used steel variant known for its susceptibility to mechanical property degradation due to corrosion. In order to decrease the corrosion rate of medium carbon steel, various protective measures are employed such as the addition of inhibitors. Dried Clove Leaf (DCL) extract was extracted and applied as an inhibitor for medium carbon steel AISI 1040 in different acidic environments. Fourier-transform infrared spectroscopy (FTIR) was conducted to analyze the compounds present in the clove leaf extract. Subsequently, corrosion rate and inhibitor efficiency were assessed to demonstrate the effectiveness of the clove leaf inhibitor. The parameters under this research included varying inhibitor concentrations for 0%, 5%, 10%, 15%, and acidic media using HCl and H2SO4. The successful extraction of DCL was confirmed by the presence of a C=C bond in the FTIR results, occurring at wavenumbers ranging from 1638 to 1514 cm-1, indicative of the presence of benzene rings corresponding to eugenol (a phenolic component). The inhibitor exhibited remarkable efficiency, reaching its peak at 96.51% when used with HCl media at a DCL concentration of 15%. This high efficiency is notably reflected in the significant reduction of the corrosion rate from 352.96 mpy to 12.31 mpy in the presence of HCl media.

Abstract

AISI 1045 material is carbon steel which is widely used in the industrial world as a material for making gears, bolts, and axles, however, in its use AISI 1045 steel has shortcomings in its hardness value. When used, AISI 1045 steel must be hardened through a hardening heat treatment process so that it is more capable of being used. It is important to carry out the hardening process so that the material has greater hardness, this property is related to wear resistance. This research was carried out with the aim of analyzing the effect of variations in holding time and variations in cooling media on the hardness and microstructure of AISI 1045 Steel. The heating temperature used was 840⁰C with a holding time of 17 and 22 minutes using air, oil, and grease cooling media. The method used to measure hardness in this research is the Brinell hardness method. The results of the research showed changes in the microstructure from initially ferrite and pearlite to bainite and martensite, the highest hardness was obtained in the specimen with oil quench media with a holding time of 17 minutes with a value of 643.35 kgf/mm2 and the lowest hardness value was obtained in the specimen with quench media air with a holding time of 22 minutes with a value of 153.44 kgf/mm2.

Abstract

Corrosion is one of the main problems causing damage to metals. The occurrence of a reaction with the surrounding environment accompanied by several factors cause deterioration so that corrosion causes damage to the material. Therefore, researchers added inhibitors as a way to control corrosion. This study used paracetamol as an inhibitor against corrosion protection of AISI 1020 steel with 3% NaCl as the media. The method used for the corrosion test was the weight loss and toughness test using the Charpy method of impact testing. This study obtained the lowest corrosion rate value at the addition of 220 ppm inhibitor concentration with immersion time for 7 days of 1.078 mpy. The efficiency observed in this study showed that adding an inhibitor concentration of 220 ppm with the immersion time of 7 days had the highest value reaching 71.42%. Moreover, the impact test results got the highest value on the 220 ppm inhibitor variation with the immersion time of 7 days, reaching 0.0817 J/
