Abstract:
Tanaman puring memiliki varietas yang sangat banyak dan terdapat sekitar 260 varietas puring yang ada di Indonesia. Puring merupakan tanaman yang memiliki warna dan bentuk daun yang beragam seperti kuning, hijau, merah dan coklat sehingga tanaman puring dimanfaatkan sebagai tanaman hias warna-warni tersebut disebabkan karena adanya bermacam-macam pigmen warna didalam daun. Dalam proses fotosintesis klorofil atau pigmen hijau daun sangat diperlukan sehingga setiap daun sangat membutuhkan klorofil. Belum ada data yang menunjukkan apakah perbedaan dominansi warna pigmen daun juga mengandung perbe

Tulisan ini membahas tentang identifikasi bentuk profil dasar daun puring (Cadiaeum Variegatum). Bentuk profil daun puring dilihat berdasarkan kontur dan sturktur dasar permukaan daun. Daun puring mempunyai ragam varietas dan tidak bisa ditentukan secara acak berdasarkan warna. Oleh sebab itu, metode indentifikasi profil dasar daun diusulkan dengan Image J. Indentifikasi profil daun menggunakan tiga jenis daun yang berbeda. Hasil menunjukkan bahwa jenis daun puring ke-1 memiliki warna hijau 75% dan kuning 25%, daun puring ke-2 mempunyai presentase warna hijau 50% dan kuning 50%, sedangkan daun

The high incidence of infection occurs due to a lack of public awareness in getting used to a clean and healthy life. Hands are one of the media for the spread of bacteria, so an antibacterial preparation is needed. Puring leaf (Codiaeum variegatum) is a plant that contains many components of secondary metabolites, one of which is tannin compounds. Based on previous research, it has been proven that the tannin group has antibacterial activity. The use of puring leaves directly on the hands is considered less practical so it needs to be formulated in the form of hand antiseptic gel preparations

Abstract:
Hydrogen cooled generators need to undergo carbon dioxide (CO2) purging before being placed into service and when taken offline. This process typically takes 4 to 12 hours, and can take as long as 36 hours in extreme cases, to fully and safely purge a generator. Reducing the volume of hydrogen gas in these generators is essential for reducing the risks of explosions. If these purge times could be shortened, improvements in safety, shorter outages, and increased production could be realized. This paper describes plant testing of a CO2 Fast Degas purging system for hydrogen cooled generators. Re

Abstract:
Abstract Effective purging of air out of a pipeline section before commissioning by direct displacement with natural gas has been safely practiced for decades with the recognition that flammable interfacial mixing zone between the driving gas (behind) and the air (ahead) is inevitable. In cases when the purge velocity is below a threshold dictated by the gravity current velocity (defined in AGA Purging Principles and Practices, 2001), natural gas being lighter than air can in fact ride over air being the heavier gas and short circuit the flow path to the vent at the other end of the pipe secti
