Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengembangkan sektor perekonomian kreatif di tempat Wisata Meranti melalui pelaksanaan pengabdian kepada masyarakat yang melibatkan pelatihan keterampilan bagi masyarakat kampung semarang Rt 27 km 15. Salah satu fokus utama adalah teknik penyablonan polyflex sebagai metode pembuatan desain pada pakaian. Langkah-langkah pelaksanaan mencakup persiapan desain, pemotongan pola, pemasangan pola pada media, aplikasi panas, dan pelepasan pola. Mitra KKN memiliki peran penting dalam mendukung program ini dengan memberikan fasilitas dan arahan kepada mahasiswa. Pelatihan sosialisasi polyflex dilakukan untuk mengenalkan bahan dan teknik penyablonan kepada masyarakat. Selanjutnya, dilakukan pelatihan dan lomba sablon baju teknik polyflex untuk memberdayakan masyarakat dalam pengembangan keterampilan. Hasil dari kegiatan ini menunjukkan peningkatan keterampilan, pemahaman akan kualitas produk, dan pemberdayaan ekonomi kreatif melalui produksi cinderamata khas. Diharapkan hasil pengabdian kepada masyarakat ini dapat memberikan kontribusi positif bagi pengembangan pariwisata dan perekonomian kreatif di wilayah kampung semarang Rt 27 km 15.

Abstract

Corrosion of metals is inevitable. One of the factors that affect corrosion is environmental conditions that contain pollutants like SO2, NO2, and Cl- which are found in many industrial and seaside areas. Surabaya is an area that has 2 types of conditions. In addition, Surabaya is the capital of the province where infrastructure development is running rapidly. Thus, this study maps the level of atmospheric corrosion in five areas in Surabaya by collecting corrosion rate data for 4 months with weight loss method using AISI 1020 Steel and SK5 Steel as test metals. XRD and SEM-EDX tests were conducted to compare the corrosion results. The average corrosion rate of low carbon steel was 0,6561 mpy and high carbon steel was 1,2523 mpy. The results concluded that the high level of atmospheric corrosivity of low carbon steel is in Sukomanunggal, Bulak, Rungkut, Pakal, Krembangan, and Bubutan sub-districts. The medium level is in Tegalsari, Gubeng, Tenggilis Mejoyo, Karang Pilang, Jambangan, Sawahan, and Dukuh Pakis sub-districts. The low level is in Lakarsantri, Mulyorejo, Simokerto, Sambikerep, Genteng, and Wonokromo sub-districts. Meanwhile, high atmospheric corrosivity levels for high carbon steel are in Krembangan, Karang Pilang, Bulak, Tenggilis Mejoyo, Pakal, and Jambangan sub-districts. The medium level is in Rungkut, Sawahan, Bubutan, Wonokromo, Tegalsari, Sukomanunggal, and Lakarsantri sub-districts. The level is in Dukuh Pakis, Genteng, Gubeng, Simokerto, Sambikerep, and Mulyorejo sub-districts. This mapping is based on the level of corrosion in each sub-district which is influenced by the presence of industry and its geographical location.

Abstract

Biomaterials are crucial for bone implants due to their biocompatible and inert nature, ensuring no adverse effects within the human body. Titanium is renowned for its exceptional corrosion resistance. This research aims to analyze the impact of annealing holding time and pH of synthetic body fluid on the hardness and corrosion rate of titanium. The annealing process was performed at 700°C, with holding times of 30, 60, and 90 minutes. As an electrolyte medium, a Hanks' solution with pH variations of 4, 6, and 8 was used and maintained at 37°C. Potentiodynamic corrosion testing demonstrated the lowest corrosion rate in specimens treated with 30 minutes of annealing at pH 8, measuring 0.32 x 10-2 mmpy. The 30-minute annealing exhibited the lowest corrosion rate, which was confirmed by Electrochemical Impedance Spectroscopy (EIS) results showing a higher Rp value, indicating a lower corrosion rate. This is attributed to the presence of a passive Rutile TiO2 layer formed during the annealing process, as confirmed by X-ray Diffraction (XRD) analysis. Metallography observations indicated that the microstructure of untreated specimens consisted of α and β phases. Scanning Electron Microscopy (SEM) analysis of specimens annealed for 30 minutes revealed an oxide layer on the surface without any visible pores. However, an increase in annealing holding time led to the formation of pores, particularly noticeable after 90 minutes of annealing. The presence of pores in the oxide layer resulted in an increased corrosion rate with longer annealing holding times. Conversely, hardness testing demonstrated that longer annealing holding times resulted in higher hardness values.
