Parameter Fisis Hilal Dalam Tinjauan Model Kastner

2025-03-18T09:49:33+07:00

Dalam makalah ini dipaparkan perjalanan penerapan model visibilitas Kastner dalam penentuan kriteria visibilitas hilal dan waktu optimum dalam kegiatan observasi hilal. Kriteria visibilitas yang dimaksud meliputi kriteria dengan modus pengamatan mata telanjang dan berbantuan alat. Untuk waktu optimum berada dalam jendela waktu sejak Matahari terbenam hingga terbenamnya Bulan pada saat observasi hilal dilakukan. Diperoleh bahwa kurva fungsi visibilitas hilal pada modus observasi dengan mata telanjang mencapai nilai maksimumnya pascaterbenam Matahari. Kondisi saat fungsi visibilitas hilal mencapai nilai positif terbesarnya ini didefinisikan sebagai “best time” atau waktu terbaik dalam mengamati hilal. Khusus untuk kasus hilal yang hanya dapat diamati dengan bantuan alat, model Kastner memprediksi kebolehjadian mengamati hilal tanpa harus menunggu terbenamnya Matahari. Berdasarkan data yang tersedia, telah diperoleh kriteria visibilitas hilal untuk wilayah tropis dan konsep “best time” dapat dirumuskan sebagai sebuah persamaan linier sederhana.

Enhancing corrosion resistance of stainless steel 316L implants: Hydroxyapatite coating via DC and AC-DC voltage electrochemical deposition

2025-03-25T11:54:00+07:00

Coating hydroxyapatite (HAp) on stainless steel 316L (SS 316L) by electrochemical deposition method (ECD) was carried out to enhance the biocompatibility and corrosion resistance of metal implants for biomedical applications. One major issue in the ECD process is the water reduction causes an abundance of hydrogen (H2) bubbles, which subsequently contribute to forming a porous HAp coating. In this study, the effectiveness of HAp deposition was compared between a direct current (DC) process and a superposition alternating current-direct current (AC-DC) process. The ECD was conducted at pH 6 and 70°C, with the DC process operating at 5 V, while the AC-DC process employed 2.5 V AC and 2.5 V DC at 60 Hz. After deposition, the samples were annealed at 600°C for 2 hours in an argon atmosphere. The corrosion resistance was examined by potentiodynamic polarization. Electrochemical analysis indicated that the AC-DC superposition technique resulted in a significantly higher polarization resistance (R_p ) of 4.87 x 104 Ω/cm2, compared to the DC sample (7.65 x 103 Ω/cm2), with a more positive potential corrosion 〖(E〗_corr) and lower corrosion current density (i_corr). The AC-DC techniques minimizing (H2) bubbles formation and promoting smoother transition, facilitated the formation of a more homogenous coating and effectively covered substrate surface, thus exhibiting better corrosion resistance. Furthermore, this enhanced corrosion resistance has significant implications for biomedical applications. By prolonging implant lifespan, reducing the release of metal ions like (nickel and chromium), and pitting corrosion in simulated body fluid.
