Abstract

Several studies reported the use of acid catalysts of esterification of glycerol to acetin derivatives and amberlysts are no exception. However, among these strong sulfuric acid catalysts, amberlyst 36 is still rarely used and hence challenging to investigate. This study aimed to determine the yield and the selectivity of the esterification reaction of glycerol into acetine derivatives using a 5% of solid catalyst amberlyst 36 at a temperature of 90°C in a reflux system. The conversion value resulting from the reaction was 80.74%, with a selectivity value of 6.8% for triacetin. FTIR and GC-MS data support the monoacetin and triacetin structures. The findings indicate that the simple method and easily obtained catalyst can produce a high yield of acetin derivatives. This method is still possibly optimized to perform maximum yield with high selectivity.

Abstract

This research aims to determine the determination of the status of the Rohingya ethnic group according to the Refugee Convention and the application of the principle of non-refoulement in handling Rohingya refugees in Indonesia in relation to the principle of sovereignty, and then whether the application of the principle of non-refoulement is absolute or not applied in Indonesia. Due to the large number of Rohingya ethnic groups entering Indonesian territory and causing social problems, security can even threaten sovereignty. The research method is normative legal research, relying on secondary data. The research results show that Indonesia is not a country that has ratified the 1951 convention, as a result, it is difficult for asylum seekers to obtain protection regarding their certainty, and considering the ongoing security situation in Myanmar, of course, the only hope for asylum seekers to achieve a long-term solution is through resettlement in third countries and even though Indonesia has not ratified the 1951 convention, Indonesia still needs to comply with the principle of non-refoulement even though there are no penalties imposed on Indonesia if Indonesia violates the 1951 convention and forces refugees to leave Indonesia considering that the convention does not explain in writing what The consequences that non-convention countries will face if they reject asylum seekers and refugees and force them to leave Indonesia. Penelitian ini bertujuan untuk mengetahui penentuan status etnis Rohingya Menurut Konvensi Pengungsi dan penerapan prinsip non refoulement dalam penanganan pengungsi Rohingya di Indonesia dikaitkan dengan prinsip sovereignty, dan kemudian apakah penerapan prinsip non refoulement ini mutlak atau tidak diterapkan di Indonesia. Di karenakan banyaknya etnis Rohingya yang masuk ke wilayah Indonesia dan menimbulkan masalah-masalah sosial, keamanan bahkan dapat mengancam kedaulatan. Metode penelitiannya adalah penelitian hukum normatif, bertumpu pada data sekunder. Hasil penelitian menunjukan bahwa Indonesia bukan merupakan negara yang meratifikasi konvensi 1951, akibatnya pencari suaka kesulitan untuk mendapatkan perlindungan terkait kepastian mereka dan mengingat situasi keamanan yang sedang berlangsung di Myanmar maka tentu saja, maka satu-satunya harapan para pencari suaka untuk mencapai solusi jangka panjang adalah melalui pemukiman kembali di negara ketiga dan walaupun Indonesia tidak meratifikasi konvensi 1951, Indonesia tetap perlu untuk mematuhi prinsip non refoulement sekalipun tidak ada hukuman yang dijatuhkan ke Indonesia apabila Indonesia melanggar konvensi 1951 dan memaksa pengungsi meninggalkan negara Indonesia mengingat di dalam konvensi tidak menjelaskan secara tertulis apa konsekuensi yang akan dihadapi negara-negara non konvensi jika mereka menolak pencari suaka dan pengungsi serta memaksa mereka meninggalkan negara Indonesia.

Abstract

The potential uses of ecologically benign nickel nanoparticle manufacturing in various sectors, such as biomedicine, energy storage, and catalysis, have garnered much interest. This paper covers green approaches to nickel nanoparticle manufacturing, which integrate natural substances as stabilizing and reducing agents with eco-friendly processes. Phytochemicals derived from bacteria, microorganisms, and plant leaf extracts can convert nickel ions (Ni2+) into nickel nanoparticles. Room temperature is used for the synthesis procedure, and neither dangerous compounds nor unusual reaction conditions are used. Using a variety of analytical methods, the resultant nickel nanoparticles were characterized. We also investigate the possibility of using the generated nickel nanoparticles as a cytotoxic, photocatalytic, antioxidant, and antibacterial agents. The antimicrobial activity of nickel nanoparticles demonstrates their potent antibacterial properties, while their antioxidant activity demonstrates their capacity to combat free radicals effectively. Furthermore, nickel nanoparticles' cytotoxic activity demonstrates their capacity to kill cancer cells, and their photocatalytic activity demonstrates their efficiency in breaking down organic contaminants. This review highlights the value of ecologically benign synthetic methods and creates new avenues for developing nickel nanoparticle applications in health and the environment.
