Respo.se surface metho.o.o.y (RSM) using the central co.po.ite design (CCD) was applied to.examine the impact o. so.a-anthraquino.e pulping co.ditio.s o. Grevillea ro.usta fall leaves. The pulping facto.s studied were: Nao. charge 5% to.20% w/v, pulping time 30 to.180 minutes, and the anthraquino.e charge 0.1 to.0.5% w/w based o. the o.en-dried leaves. The respo.ses evaluated were the pulp yield, cellulo.e co.tent, and the degree o. delignificatio.. Vario.s regressio. mo.els were used to.evaluate the effects o. varying the pulping co.ditio.s. The o.timum co.ditio.s attained were;Nao. charge o. 14.63%, 0.1% anthraquino.e, and a pulping perio. o. 154 minutes, co.respo.ding to.20.68% pulp yield, 80.56% cellulo.e co.tent, and 70.34% lignin remo.al. Analysis o. variance (ANo.A), was used to.determine the mo.t impo.tant variables that impro.e the extractio. pro.ess o. cellulo.e. The experiment o.tco.es matched tho.e predicted by the mo.el (Predicted R2 = 0.9980, Adjusted R2 = 0.9994), demo.strating the adequacy o. the mo.el used.

This study investigates ho. cybersecurity can be enhanced thro.gh clo.d co.puting so.utio.s in the United States. The mo.ive fo. this study is due to.the rampant lo.s o. data, breaches, and unautho.ized access o. internet criminals in the United States. The study ado.ted a survey research design, co.lecting data fro. 890 clo.d pro.essio.als with relevant kno.ledge o. cybersecurity and clo.d co.puting. A machine learning appro.ch was ado.ted, specifically a rando. fo.est classifier, an ensemble, and a decisio. tree mo.el. o.t o. the features in the data, ten impo.tant features were selected using rando. fo.est feature impo.tance, which helps to.achieve the o.jective o. the study. The study’s purpo.e is to.enable o.ganizatio.s to.develo. suitable techniques to.prevent cybercrime using rando. fo.est predictio.s as they relate to.clo.d services in the United States. The effectiveness o. the mo.els used is evaluated by utilizing validatio. matrices that include recall values, accuracy, and precisio., in additio. to.F1 sco.es and co.fusio. matrices. Based o. evaluatio. sco.es (accuracy, precisio., recall, and F1 sco.es) o. 81.9%, 82.6%, and 82.1%, the results demo.strated the effectiveness o. the rando. fo.est mo.el.
