Abstract

Briket adalah bahan bakar padat, maka didalam penyalaannya memerlukan waktu sedikit lebih lama dibandingkan dengan bahan bakar cair dan gas. Reaksi pembakaran dari bahan bakar padat berupa arang karbon dengan oksigen pada permukaan partikel akan menghasilkan karbon monoksida dan karbon dioksida. Sebelumnya ditimbang massa biobriket, biobriket yang telah jadi dimasukkan kedalam Reaktor, temperatur diset masing-masing campuran briket pada suhu 300°C sampai 350°C dan regulator dinyalakan, setelah temperature tercapai maka laju alir dialirkan dari tabung oksigen menuju Reaktor sebanyak 1 liter/menit. Kemudian dari hasil pembakaran yang terjadi didalam reaktor terjadi reaksi dimana C + O2 → CO2 + H2O yang kemudian akan diteruskan menuju Kondensor, pada proses kondensasi dihasilkan berupa kondensat yang dianggap H2O yang keluar dan gas yang akan menekan pada tangki penampung yang beisi air sehingga akan keluar air menuju penampungan gelas ukur, air yang keluar dianggap sebagai CO2, dicatat ketinggian volume kondensat dan gas selang waktu 10 menit sampai 60 menit, setelah itu ditimbang massa briket setelah pembakaran, prosedur ini diulangi untuk campuran biobriket lainnya. Berdasarkan hasil penelitian dapat disimpulkan bahwa temperatur optimum dalam proses pembakaran yaitu 300°C dengan nilai konstanta reaksi pada campuran batubara dengan biomassa kulit durian 14647.13/menit, tempurung kelapa 14400.24/menit, serbuk gergaji 15244.90/menit.

Abstract

In this study, silica was synthesized from rice husk waste using NaOH as a reagent. Rice husk waste was selected as the silica source due to its abundant availability and high silica content. The synthesis method involved silica extraction with an alkaline solution followed by precipitation using various types of acids to obtain optimal silica. The extraction process was conducted with two time variations: 60 minutes and 90 minutes. The physicochemical characteristics analyzed included moisture content, humidity, and adsorption capacity. The results indicated that silica extracted with a 90-minute variation was more optimal, as evidenced by a humidity level of 48% and a moisture content of 0.14%.

Abstract

In today's modern era, where advances in technology and information are developing very rapidly coupled with current advances in technology and information, it has made it easier for customers to carry out transactions and carry out their daily activities. Several shops selling goods, one of which is a shoe store in the Gowa area, are mostly still having trouble getting customers around the store because the location is less crowded by the public. This study aims to create a web-based shoe sales application to try to present shoe sales information to customers quickly and accurately and make it easier for customers to make purchases. The floating method used in developing this web-based shoe sales application system uses the RAD (Rapid Application Development) method. From the results of discussing this web-based shoe sales application, of course, it can be used as a solution to existing problems. With this application it will be very useful in promoting products to a wider range.
