Abstract

Corrosion is a physical interaction between the metal and its environment, which results in changes in the metal's properties due to chemical or electrochemical reactions. The corrosion rate can be reduced by adding a corrosion inhibitor. Uses of nanotechnology for corrosion prevention is one of the first technical because almost made structures rely on the stability of a 1–2 nm thick passive film which provides stability to the underlying material. Herein we report the thermodynamic and kinetic analysis of carbon-dots from Durian as inhibitor copper corrosion. To test the anticorrosive performance and analyze thermodynamic properties in its role as a corrosion inhibitor on copper using potentiodynamic polarization. The thermodynamic-kinetic parameters of corrosion obtained values of H‡ = 60.44 kJmol-1, ΔS‡ = -73.9 kJmol-1, and ΔG‡ = 82.83 kJmol-1, show that the attendance of C-dot as a corrosion inhibitor causes a non-spontaneous reaction rate to be proven by increasing spontaneity (ΔG‡). The value of activation energy samples was higher than the blank, indicates the presence of C-dot effective to reduce the rate of corrosion of the metal.

Abstract

Dalam penelitian ini, kami melaporkan katalis basa heterogen CaO/K2O yang disintesis dan dikarakterisasi dari batu gamping untuk transesterifikasi minyak jelantah menjadi biodiesel. Konversi batu gamping menjadi katalis CaO melalui kalsinasi pada suhu 1000°C selama 3 jam. Katalis CaO/K2O dibuat dengan metode impregnasi CaO oleh KOH. Katalis dikarakterisasi dengan menggunakan instrumen X-Ray Diffraction (XRD) dan Scanning Electron Microscopy-Energy Dispersive X-Ray (SEM-EDX). Katalis CaO/K2O dibandingkan dengan katalis CaO untuk mempelajari aktivitasnya dalam proses transesterifikasi dalam kondisi yang sesuai (suhu reaksi 65ºC, pemuatan katalis 5% berat, rasio molar minyak terhadap metanol 1:2, dan waktu reaksi 2 jam). Hasil pengujian katalis menunjukkan aktivitas katalitik dengan rendemen Fatty Acid Methyl Ester (FAME) sebesar 65,2 %. Penggabungan K2O ke dalam katalis CaO meningkatkan sifat kebasaan sehingga meningkatkan aktivitas katalitik transesterifikasi.

Abstract

Chemistry is not merely a science that only studies theory in class. Chemistry learning requires practical or experimental activities to observe and directly apply chemical concepts during face-to-face meetings in class. Meanwhile, the unavailability of laboratory facilities is one of the factors in not carrying out chemistry practice. This causes students difficulties in understanding the concept of chemistry as a whole and can potentially reduce learning motivation. This public service activity aims to implement the Hyperchem software for teachers and students of SMA Negeri 1 Mawasangka Timur as an alternative solution for chemistry labs in the form of electronic labs. The chemical topics selected and considered suitable for this type of practice were the structure and properties of chemical compounds. This activity is carried out in the form of a workshop. Workshop materials use lectures, simulations, discussions, and question-and-answer models. The activity's results showed the workshop participants' enthusiasm to use the Hyperchem software as a chemistry lab media. This is reflected in the evaluation of the workshop implementation, which is carried out by assessing the response of the workshop participants based on indicators of relevance, the ability of the presenters, ease of use, availability, and usefulness of the Hyperchem software. The evaluation results show that the workshop and the implementation of the Hyperchem software as an electronic practice media for visualizing the structure and properties of chemical compounds received a positive response from the workshop participants.
