Abstract

Baja AISI 4140 merupakan baja paduan menengah yang sering digunakan dalam aplikasi teknik, termasuk pada komponen kapal, karena memiliki kekuatan tinggi dan potensi untuk ditingkatkan sifat mekaniknya melalui perlakuan panas. Penelitian ini bertujuan untuk mengkaji pengaruh variasi waktu tahan pada proses perlakuan panas terhadap perubahan struktur mikro, kekerasan, dan laju korosi baja AISI 4140. Perlakuan panas dilakukan dengan memanaskan spesimen pada suhu 800°C selama 30 menit dan 45 menit, kemudian diikuti proses quenching menggunakan oli SAE 10W-40. Spesimen tanpa perlakuan panas digunakan sebagai pembanding. Struktur mikro diamati menggunakan mikroskop optik Olympus BX51M, kekerasan diuji dengan metode Vickers menggunakan beban 5 kg, dan korosi diuji dengan metode kehilangan berat dalam larutan NaCl 3,5%. Hasil pengamatan menunjukkan bahwa semakin lama waktu penahanan, struktur mikro didominasi oleh fasa martensit yang lebih halus dan homogen. Hal ini berdampak langsung pada peningkatan kekerasan material, di mana spesimen dengan waktu tahan 45 menit menunjukkan nilai kekerasan tertinggi 658,14 HV dibandingkan spesimen lainnya. Nilai laju korosi tertinggi diperoleh Q-30 melalui pengujian selama 96 jam sebesar 38,02 mpy

Abstract

This paper examines the interplay between ethical norms and anti‐ethical norms in shaping investment decisions within Indonesia’s renewable energy sector. Drawing on Mertonian ethical norms as a theoretical backbone and contrasting them with non‐market strategy perspectives, the study reviews how business ethics intersect with renewable energy policy, investment, and sustainable development in Indonesia. Using recent data from national energy statistics and empirical studies on renewable energy and ESG disclosure , the paper develops a research framework. By combining institutional theory and stakeholder theory, this study uses a theory-driven conceptual qualitative approach to provide a normative-analytical framework that clarifies how ethical standards and non-market tactics influence Indonesia's investment in renewable energy. The framework suggests that a balanced approach—integrating both ethical imperatives and pragmatic market strategies—can drive progress toward national targets such as the Golden Indonesia 2045 vision and the Paris Agreement’s zero‐carbon goals.

Abstract

Copper (Cu) is widely used in many sectors, such as drinking water piping, heat exchangers, and medical equipment. The present research conducted an electrodeposition of Cu over an aluminum (Al) alloy substrate under the influence of various magnetic poles and rotating speeds. In the present study, a number of investigations, including deposition rate, current efficiency, coating thickness, surface morphology and phase, crystallographic orientation, antibacterial activity, electrochemical behavior, and hardness test were conducted. Increasing the rotation speed promoted to enhanced deposition rate and current efficiency for both magnetic poles influence. An increase in the deposition rate from 12.83 to 13.67 µm/h led to the increasing thickness, a change in surface morphology near the spheroidal, becoming a faceted structure. Presenting and rising in the rotation of a magnetic field led to a reduced surface roughness and crystallite size of Cu film for both magnetic poles influence. The Cu film made without spinning magnetic had a characteristic of highest bacterial inhibition zone around 2.50 ±0.56 cm². The CuRN50 sample had the lowest corrosion rate at around 0.055 mmpy, while the CuRS100 sample had the highest hardness value at approximately 80.72 HV for having the lowest crystallite size. Cu coated onto Al alloy could enhance its properties, such as being antimicrobial, being resistant against corrosion and having the hardness value.

Abstract

In the present study, Cu films were made over Al alloy using the electrodeposition technique. Electrodeposition conducted at various currents (80, 100, and 120 mA), with and without influence by a rotating magnetic field (100 rpm of rotation). 0.5 M CuSO4 + 20 mL of H2SO4 was used for electrolyte solutions. The sample before and after electrodeposition was weighed using digital scale to calculate deposition rate and current efficiency. All formed Cu films were characterized using X-ray diffraction (XRD), attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), Scanning electron microscopy equipped with Energy dispersive spectroscopy (SEM-EDS), and Potentiostat apparatus. Furthermore, antibacterial activity using Staphylococcus aureus was also investigated. Increasing the current of electrodeposition leads to an increase in deposition rate and current efficiency for both conditions (with and without rotating magnetic field influence). Based on the XRD and ATR-FTIR investigation, Cu was successfully deposited onto Al surface. Currents used for the electrodeposition process between 80-100 mA would result in a faceted structure, while using 120 mA results near to spheroidal. Shifting to higher currents leads to decreases in grain sizes and presenting a rotating magnetic field also enhances the grain size. Current and rotating magnetic influences are not linearly influencing corrosion potential, corrosion rate and antibacterial activity. The sample made using higher current plus influencing with a rotating magnetic field has less corrosion rate and higher area of inhibition at around 0.808 mmpy and 4.01 cm2.

Abstract

This study was conducted to determine the effect of the radiation source and radiation time on the methylene blue (MB) solution by adding Ni-Cd/Al2O3 to the percent degradation of MB. To investigate similar purposes, the pH of the MB solution varied as well. The preparation, characterization, and photocatalytic activity of Ni-Cd/Al2O3 are three steps in this research. The Ni-Cd was prepared by mixing Ni(NO3)2.6H2O and Cd(NO3)2.4H2O. Various concentrations of Ni-Cd were mixed with Al2O3, then heated, stirred, dried, and calcined to form Ni-Cd/Al2O3 powder. The dried powder catalysts were characterized using Field emission scanning electron microscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDS), Brunauer-emmett-teller (BET), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and Diffused reflectance spectrometer spectra (DR-UV-Vis). Higher degradation was observed at pH 11, when MB was degraded by 68% and 76% using the 5Ni-2Cd/Al2O3 and 6Ni-1Cd/Al2O3 catalysts, respectively. The 6Ni-1Cd/Al2O3 sample has higher absorption, less surface area, and less band gap; therefore, it has higher performance against degraded MB in the solution. In summary, 6Ni-1Cd/Al2O3 is capable of degrading MB and can be utilized in MB dye waste. Copyright © 2023 by Authors, Published by BCREC Group.

Abstract

Microstructure modification of the plain carbon steel usually enhances hardness and corrosion resistance. Therefore, in the present research, the microstructure of plain carbon steel is modified by heating it in an electric furnace using various temperatures and then quenching it in engine oil to enhance corrosion resistance and hardness. Several characterizations were conducted, such as microstructure, hardness, and electrochemical behavior. The microstructure evolution indicates a clear transformation of martensite morphology with decreasing austenitizing temperature. Decreasing the furnace's heating before quenching could increase the specimens' hardness and corrosion resistance, with values around 586.36 HV and 0.135 mmpy. Therefore, the optimal heat treatment condition for plain carbon steel components in marine environments was found at 800 °C based on the results of this study.

Abstract

Magnesium (Mg) alloy is used for various medical purposes, such as bone implants. In the present study, MgAlSixZn alloys were created utilizing the gravity casting by adding various Zinc (Zn) (x is 0, 0.5, 1.2, and 1.7 wt.%) and then homogenized at 400 ◦C for around two hours. MgAlSixZn as homogenized samples were investigated for microstructure, phase structure, electrochemical behavior, surface morphology, bacterial activity, hardness, and thermal behavior using an optical microscope, XRD, Potentiostat, SEM-EDS, digital camera, Vickers hardness test, and Thermogravimetric apparatus, respectively. Several findings include that increasing Zn content implies a grain growth inhibition mechanism facilitated by Zn segregation at grain boundaries, increased corrosion rates, a rise in the hardness, and increased weight loss. It should be noted that the increase in the corrosion rate and weight loss occurs linearly for Zn addition in the Mg alloy until 1.2 wt.%. An increase in Zn concentration causes the peak shift in MgAlSi-based alloy samples, but no crystallographic orientation is apparent. At the end, the highest corrosion rate and inhibition area are observed in MgAlSi1.2Zn, which indicates that it is suitable for biodegradable orthopedic wire.

Abstract

Hardfacing adalah salah satu teknik dalam pengelasan yang berfungsi untuk meningkatkan nilai kekerasan permukaan suatu material. Selain itu untuk meningkatkan kekerasan permukaan dapat juga dilakukan dengan melakukan perlakuan panas pada material. Umumnya hardfacing dilakukan pada material baja karbon rendah, karena baja karbon rendah tidak bisa ditingkatkan kekerasannya dengan perlakuan panas. Untuk itu akan dilakukan kombinasi dari proses hardfacing secara multilapis dan dilanjutkan dengan perlakuan panas dengan tujuan untuk mendapatkan kekerasan lapisan yang optimum. Metodologi dalam penelitian ini adalah akan dilakukan pengelasan hardfacing secara multipis dimana lapis pertama dengan elektroda AWS A5.13 EFe2, lapis kedua dengan elektroda AWS A5.1 E7018 dan lapis ketiga dengan elektroda AWS A5.13 EFe2. Setelah selesai proses hardfacing, kemudian dilakukan perlakuan panas serta pendinginan cepat dengan dua media yang berbeda yaitu oli dan minyak sayur. Hasil dari penelitian ini adalah berdasarkan foto struktur mikro, struktur yang terbentuk adalah perlite, ferrite dan martensite dan kekerasan yang dihasilkan untuk sampel tanpa perlakuan panas, sampel dengan pendinginan oli dan sampel dengan pendinginan minyak sayur masing-masing adalah 468,1, 490,4 dan 532,4 VHN. Kesimpulan dari penelitian ini adalah sampel dengan pendinginan minyak sayur memiliki kekerasan tertinggi karena lebih banyak martensite yang terbentuk. Sedangkan sampel tanpa perlakuan panas menghasilkan kekerasan terendah karena struktur yang terbentuk ferrite dan pearlite.
