Abstract

Iklim tropis di daerah pantai dapat mempengaruhi ketahanan material baja untuk struktur kendaraan sepeda motor, karena iklim daerah pantai dapat mnimbulkan korosi pada material baja yang mana iklim lembab dapat meningkatkan tingkat korosi pada baja. Penelitian ini bertujuan untuk mengetahui laju korosi karena pengaruh iklim di daerah pantai terhadap ketahanan jenis baja yang digunakan pada struktur kerangka sepeda motor dengan perlakuan pemaparan langsung, bending, dan pengelasan. Metode yang digunakan dalam penelitian ini adalah dilakukan pengujian secara eksperimen yaitu metode weight loss and gravimetry. Hasil penelitian ini menunjukkan bahwa penggunaan baja dengan dimensi dan ketebalan tertentu serta pengelasan dengan berbagai proses menunjukkan tingkat korosi yang tinggi. Sedangkan pengujian laju korosi pada baja ASTM A36 setelah proses bending menunjukkan bahwa semakin lama waktu pencelupan, laju korosi semakin kecil. Penelitian ini juga menemukan bahwa laju korosi terbesar terjadi pada menit ke-30 saat menggunakan metode celup diam sebesar 156,46 mmpy dengan sudut bending 1800 . Pengelasan juga memiliki pengaruh terhadap laju korosi yang mana korosi pitting lebih dominan terjadi pada base metal dari pada welded metal. Perlakuan inhibitor dan pelapisan anti korosi diperlukan untuk mencegah korosi pada baja yang terpapar atmosfer iklim tropis di daerah pantai.

Abstract

The increasing demand for sustainable and environmentally friendly corrosion inhibitors has driven research toward green alternatives to conventional toxic inhibitors. This study investigates the corrosion protection performance of garlic extract (Allium sativum) as an eco-friendly green inhibitor for stainless steel 316L in 3.5% NaCl marine environment. The inhibition efficiency was evaluated using electrochemical potentiodynamic polarization techniques, complemented by comprehensive surface characterization through scanning electron microscopy with energy-dispersive X-ray spectroscopy (SEM-EDX), Fourier transform infrared (FTIR) spectroscopy, Raman spectroscopy, electrochemical impedance spectroscopy (EIS), and cyclic voltammetry analysis. Electrophoretic deposition (EPD) was employed to apply garlic extract concentrations of 8, 10, and 12 mL onto SS316L specimens. Results demonstrated significant corrosion rate reduction from 0.0082732 mmpy (unprotected specimen) to 0.0014547 mmpy with 12 mL garlic extract treatment, achieving maximum inhibition efficiency of 82%. EIS revealed substantial increase in charge transfer resistance (>170 kΩ), while electrochemical analysis demonstrated mixed-type inhibition behavior with reduced corrosion current densities. SEM-EDX confirmed the formation of protective Fe2+-allicin complex layers on the metal surface, while Raman spectroscopy showed substantial reduction in corrosion products (a-Fe2O3 and y-FeOOH) formation. Cyclic voltammetry demonstrated a five-order-of-magnitude reduction in diffusion rate, confirming exceptional barrier properties. The superior performance is attributed to the chemisorption of sulfur and oxygen-containing compounds in allicin molecules onto active steel sites, forming stable protective films. This green inhibitor demonstrates excellent potential for sustainable corrosion protection in marine and industrial applications, offering an environmentally benign alternative to synthetic inhibitors.

Abstract

In the automotive world, plastic products are components that cannot be separated. Almost all automotive products use plastic because it is easy to produce, and the price is relatively cheap compared to other materials. For applications such as covers, the demand on plastic surface quality are higher than for different uses. Therefore, a lot of costs are incurred to achieve this quality. However, ongoing efforts have decreased the time and expense of developing plastic molds. Many researchers have conducted studies to improve the quality of these products. This review consolidates several research articles on optimizing plastic injection processes to reduce defects and improve product quality. Techniques such as Taguchi Method, Response Surface Methodology (RSM), Artificial Neural Networks (ANN), and Finite Element Method (FEM) were evaluated in this research. This review highlights the importance of process parameters such as melt temperature, injection pressure, and cooling time, as well as the role of digital simulation in designing efficient and sustainable molds. The results of the study show that in several studies, defects often occur in the product without carrying out the optimization process. Still, the Taguchi and ANOVA methods can reduce the weld line and sink after optimizing the process parameters, such as melting temperature, injection pressure, cooling time, and injection speed. Mark up to 30%. These findings highlight the potential of these techniques to significantly improve product quality and support more sustainable manufacturing practices in the plastic injection molding industry.

Abstract

6061 aluminum alloys are widely used in automotive, marine, and aerospace industries, yet their high susceptibility to corrosion in acidic and chloride environments remains a challenge. Bio-based inhibitors from natural sources have emerged as sustainable alternatives to toxic synthetic chemicals. This review synthesizes findings from published studies on AA6061 alloys and composites, integrating evidence from Potentiodynamic Polarization (PDP), Electrochemical Impedance Spectroscopy (EIS), and Scanning Electron Microscopy (SEM). Cross-study evaluations show that inhibition efficiency depends on inhibitor type and mechanism. Reports indicate that Boswellia serrata provides only moderate protection (~70%) due to weak physiosorbed films that are unstable under flow, whereas Alocasia odora achieves higher efficiency (~94% in HCl) through chemisorption with cathodic inhibition. Aerva lanata demonstrates ~88% efficiency in chloride-based fiber-metal laminates via polyphenolic adsorption, while glutathione provides ~80% protection at 0.75 mM through multisite coordination. Pectin consistently achieves the highest efficiency (~95% in mild acidic media) by forming compact polymeric films that increase charge-transfer resistance and reduce double-layer capacitance. This synthesis indicates that chemisorption-based inhibitors (e.g., pectin, Alocasia) generally outperform physisorption-based systems (e.g., Boswellia) because they form stronger and more stable films. Reported studies highlight both advantages and limitations: natural inhibitors are effective and eco-friendly, but most evaluations remain short-term and laboratory-based. Key gaps include durability testing, advanced characterization (XPS, ToF-SIMS, Raman, AFM), galvanic effects in composites, and poor hydrodynamic stability of physisorption systems. Future work should explore hybrid strategies, synergistic multi-inhibitor approaches, and validation under real-sea conditions to enable scalable and industrially viable corrosion protection.

Abstract

Vocational high school accounting teachers who are members of the Tangerang City Accounting MGMP (64 vocational high schools) face a competency gap in understanding and implementing the Financial Accounting Standards for Micro, Small, and Medium Entities (SAK EMKM), particularly in preparing financial reports based on real cases. This condition has a direct impact on students' low readiness to face the demands of business and industrial competencies. As a solution, this Community Service (PkM) activity offers practice-based training and mentoring that includes strengthening the conceptual understanding of SAK EMKM as well as technical practice in preparing financial position statements, income statements, and notes to the financial statements using real MSME cases. The activity was carried out in three stages, namely: pre-test and material presentation, guided practice in preparing financial reports, and post-test and reflection. The results of the activity showed an average increase in participants' conceptual understanding scores of 35% and technical skills in preparing financial reports by 40% based on the pre-test and post-test results. This activity contributes significantly to strengthening the pedagogical capacity of vocational accounting teachers and improving the quality of accounting learning based on the latest standards in Tangerang City vocational high schools on an ongoing basis
