Sarden merupakan salah satu makanan instan yang diunggulkan di Indonesia. Namun, ada berbagai masalah yang ada didalam pengalengan ikan sarden, diantaranya adalah korosi. Salah satu upaya pencegahan korosi adalah dengan menggunakan metode pelapisan. Inhibitor organik merupakan pelapis yang harganya terjangkau dan mudah didapat di alam untuk industri pangan. Penelitian ini akan menggunakan inhibitor organik dengan metode pelapisan menggunakan ekstrak gambir dan kopi pada sambungan las SMAW stainless steel aisi 304 karena penerapan metode tersebut mudah, bahan mudah didapat dari alam dan aman untuk lingkungan industri. Penelitian ini mengambil sample pipa saluran saus sarden di PT Balmbangan Food Packers Indonesia. Sambungan pipa yang terkorosi diambil untuk analisa kronologi laju korosi yang terjadi pada sambungan pipa dengan menggunakan SEM, pipa di potong searah dengan garis pipa untuk dapat menampilkan struktuk sambungan secara rinci. Dalam penelitian ini penambahan inhibitor organik kombinasi ekstrak daun gambir (uncaria gambir roxb) dan ekstrak kopi (coffea) pada sambungan las SMAW plat baja tahan karat AISI 304 dapat menurunkan laju korosi pada sambungan plat baja tahan karat dari laju korosi sebelumnya. Perbandingan kombinasi terbaik inhibitor yakni 70% ekstrak kopi dan 30% ekstrak gambir.

“…It concluded that the silica with the dip-coating technique at the variable concentration of water glass was 3.6%, the concentration of the TMCS solution was 1.5 M, and the modification time was 13 hours, which resulted in hydrophobic glass with the most significant contact angle obtained at 118˚C. But behind all the advantages, silica also has brittle and unstable disadvantages (Rochmat et al 2017).…”

Corrosion is damage due to chemical reactions between metals or metal alloys with their environment. The use of coatings can reduce the rate of corrosion, but it is constrained by stability for a long time, so it is necessary to try other protections against mild steel that can cover the metal with a coating material. This research focuses on mild steel's bio coating expertise using 1M NaOH corrosive media using natural ingredients of rice husk extract and dammar resin. Rice husk and resin are plants that can be used as bio coating materials. Rice husk extract contains several compounds that can be used to inhibit the corrosion rate, one of which is silica. In contrast, dammar resin is a natural polymer with flexible and stable properties that can prevent corrosion. This study aimed to determine the effect of the components of the bio coating material (rice husk extract and dammar resin) on the ability to protect mild steel from 1M NaOH corrosive media by calculating the corrosion rate and efficiency of the bio coating material. There are five stages in the research: the sample preparation stage, the stage of making latex solutions, the stage of making bio coating products, the stage of metal coating with bio coating materials, and the inhibition efficiency testing phase. The method used is the weight loss method to determine the rate of corrosion formed. This study obtained the highest inhibition efficiency (IE%) of 83.23% at a bio coating concentration of 1500 ppm, with a temperature of 40˚C, and an immersion time of 1 hour.

“…Modified silica can be used to produce superhydrophobic surfaces [17]. Silica, especially in Indonesia, carries the potential as a coating material due to its good adhesion and protective properties, which can withstand the diffusion of water vapor, ions, and oxygen in metal surfaces [18]. Silica as a coating material has been developed in many studies, such as that conducted by Ambarwati and Samsiadi (2010) [19], entitled Hydrophobic Coating of Glass with Waterglass-Based Sol-Gel Method.…”

Prevention of material degradation can be achieved through the coating. Surface coating is an economically advantageous method in producing desired characteristics and auxiliary aesthetics of surface material. Modern coating processes usually use nanomaterial technology made from silica. Silica can be taken from various sources, such as bagasse waste. Bagasse has high silica content up to 88%. Coating material from silica has good adhesion, good protective properties that allow it to withstand the diffusion of water vapor, ions, and oxygen to metal surfaces. Modified silica can be used to produce superhydrophobic surfaces. The addition of vinyl groups to silica can improve the elastic and mechanical properties without much variation in density or thermal conductivity. The addition of vinyltriethoxysilane can create uniform distribution of nanoparticles. Modification of silica can be done to procure anti-bacterial properties. Copper (Cu) is often used as a high activity anti-bacterial with a fairly affordable cost. With the supplementary anti-bacterial properties, material damages attributed to bacteria may be prevented or reduced. This review aims to provide an overview of the production of superhydrophobic coatings using different methods, analyze the characteristics of synthesized materials, and choose suitable methods for producing superhydrophobic coatings. This review proposes the fabrication of silica superhydrophobic coating with the sol-gel method modified through the addition of vinyl and Cu as an anti-bacterial. This recommendation is based on the literature study that has been carried out.
