Abstract

Milling is widely applied to process train components, especially for finishing wheel-set, boogie frames, and slotting shafts. The cutting forces of milling during operation is important to analyze because they affect on the final product. The analysis can be experimental data observation or simulation. This article presents simulation of cutting forces in up-milling with various input parameters using Octave open software. The simulation results showed that the exit angle (?e) was 80o and 60o for simulation 1 and simulation 2, respectively. The start angle (?s) was 0o for both simulation because it was up-milling process. Since the effective cutting angles were less than the interval angle of cutting edges (90o), only single cutting edge was involved in cutting. In addition, the cutting force was influenced by the cutting parameters, so that there were cutting force fluctuations during machining process. Differences in radial depth of cut, feed per tooth, and effective cutting angle affected in the differences of the cutting force quantity. In simulation 1, the resultant cutting force reached 400 N, while the cutting force Fx and Fy are 250 N and 325 N, respectively. In simulation 2, the resultant was 700 N, and 500 N and 420 N for Fx and Fy cutting forces, respectively. Spindle rotation speed did not affect on the quantity of cutting force but affects on the cutting time. In simulation 1 with a spindle speed of 7500 rpm, it took a cutting time of 0.008 seconds. While in simulation 2, the cutting time was slower, namely 0.012 seconds. This was because the spindle rotation speed reduced to 5000 rpm. The simulation also proved the characteristic frequency of milling process; tooth passing, and several harmonic frequencies.

Abstract

The development of information technology today has experienced very rapid progress. Various communication media compete in providing information without limits. The world is now and is changing, rolling in the process of information and communication revolution that gave birth to a new civilization, making it easier for humans to interact and increase social mobility. Inevitably, today's society has turned into a society that is very dependent on information technology today, both for the sake of knowledge, academics, entertainment, commerce and the spread of certain religions and so on. The development of information technology does not always have a positive impact on human life, even some academics and experts actually worry about the negative impacts brought by the flow of information technology advancements at this time. On the other hand, this can be an effective medium for human improvement or improvement in a better and advanced direction. Including being an effective medium in the development of religion (Islam) or specifically for the benefit and development of future da'wah. One of the da'wah media used is the da'wah bil qolam or da'wah with a pen which is currently synonymous with the world of journalism that is very attached to the utilization of the development of information technology. Therefore journalism as an instrument of da'wah communication must really be utilized to the maximum extent possible for the development and effectiveness of Da'wah itself. Therefore, the fundamental principles and ethics in journalistic communication according to the Islamic view by utilizing the information technology must be a moral foundation held firmly by journalists/actors so as to bring the benefit of the people and theattainment of the objectives of Islamic da'wah effectively and comprehensively.

Abstract

Hyperpigmentation is a disorder of the gingiva caused by various factors including heredity, disease, drugs, smoking habits. This can occur because of the accumulation of melanin pigment in the basal gingival layer resulting in a brownish or blackish color on the surface of the gingiva which when viewed aesthetically is not good because it is not like the normal gingival color of coral pink. Objective: to get the gingival color back to normal, namely coral pink. Management in cases of pigmentation using the surgical method by scrapping using a scalpel No.15. In this study there were 3 cases, namely, case 1, a 20-year-old female patient had genetic or genetic hyperpigmentation. Case 2, a 27-year-old male patient had genetic or genetic hyperpigmentation. Case 3, a 24-year-old female patient had gingival pigmentation due to smoking habits. The results of surgical management in all three cases, namely the gingival depigmentation method by scrapping gave a good esetetic result, but for gingival hyperpigmentation in cases 1 and 2 it could recur later.

Abstract

ABSTRACT The Covid-19 pandemic situation has affected community activities, work, income whichdecreased, psychological disorders such as stress, and limited accessibility to dental practice service,which is now for emergency cases only. This condition can affect oral health in the community. Thisstudy aimed to assess the oral health condition in the community during the Covid-19 pandemic. Thisstudy was implementing a cross-sectional research design. Data were obtained from onlinequestionnaires with the respondent's consent. The sample selection with inclusion criteria comprised 1960yearsoldwholivedinBandungWestJava.Theself-reportquestionnairefororalhealthassessmentwasfollowed,thepreviousresearch,byLevinetal.,2013.Ithasbeentrans-adaptedtoBahasaIndonesiaandvalidated.Respondentsofthestudywere380participants.Poororalhygienemaintenancewasthewrongfrequencyofbrushingteeth(12.1%),onlyvisitingthedentistwhenhavingatoothache(72.9%),andsmoking(7.9%).Oralhealthproblemsincludegingivalbleedingonbrushing(15.3%),toothmobility(13.2%),tooth cavities (62.9%), toothache (27.1%), and bad breath (22.6%). Most of the oral healthproblems were tooth cavities followed by toothache.

Abstract

ABSTRACT Periodontitis is a disease of surrounding dental tissue with a prevalence of 74.1% inIndonesia. Many studies show periodontitis plays a role in the progression of atherosclerosis. Therelationship between these two conditions shows that scaling root planing intervention can reduce therisk of atherosclerosis. This study aimed to know the efficacy of scaling root planing on changes ininflammatory biomarkers in periodontitis patients with atherosclerosis. This systematic literature reviewwas conducted using the Rapid Review method that refers to the Preferred Reporting Items forSystematic Review and Meta-Analysis (PRISMA) guidelines. Electronic searches were carried out from 4electronic databases, including the National Library of Medicine (Medline / PubMed), The CochraneLibrary, EbscoHOST, and SAGE Journal. Inclusion and exclusion criteria selected 6 RCT articles to beanalyzed qualitatively. Within 2 to 6 months, research in 6 RCT articles showed the results insignificantly reducing CRP levels as the main biomarkers of atherosclerosis after scaling root planingintervention. Other biomarkers that were also assessed are cytokines levels, lipid profile components,WBC, and fibrinogen. Overall results showed a positive effect of scaling root planing intervention inreducing the inflammatory biomarker levels of atherosclerosis in periodontitis patients withatherosclerosis. The treatment of scaling root planing is considered effective in reducing theinflammatory biomarker levels of atherosclerosis in periodontitis patients with atherosclerosis to reducethe level of risk.
