Graf pembagi tak nol dari R yang dinotasikan dengan Q(R) merupakan graf sederhana yang himpunan vertex-nya adalah V(Q(R))=R{0,1,-1} dimana dua vertex berbeda x akan y adjacent jika dan hanya jika xy tak nol atau yx tak nol. Penelitian ini bertujuan untuk mengkaji sifat-sifat dasar graf pembagi tak nol dari ring suatu ring.  Sifat-sifat tersebut kemudian digunakan untuk menyelidiki syarat keterhubungan graf pembagi tak nol dari suatu ring. Metode yang digunakan dalam penelitian ini adalah studi literatur, yaitu dengan menghimpun dan mengkaji ulang berbagai sumber pustaka yang terkait dengan topik penelitian. Berdasarkan penyelidikan yang dilakukan, diperoleh hasil jika himpunan vertex V(Q(R)) mempunyai elemen invertible, maka Q(R) merupakan graf yang terhubung. Kemudian untuk kasus ring Zn diperoleh graf pembagi tak nol dari ring Zn atau Q(Zn) akan menjadi graf terhubung jika dan hanya jika n bukan diantara {1,2,3,6}. Selain itu, suatu graf Q(R) akan menjadi graf terhubung jika R adalah ring tereduksi dengan V(Q(R))>3.","PeriodicalId":300313,"journal":{"name":"Kubik: Jurnal Publikasi Ilmiah Matematika","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139210176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each treatment has its own advantages and disadvantages. In this study, a mathematical model was developed to describe how the immune system, tumor cells, and normal cells interact when all three types of therapy are used to treat cancer patients. To determine the effectiveness of various treatments, numerical simulations of eight different treatment strategies were performed. These simulations measured how much the concentration of immune cells, tumor cells, and normal cells decreased as a result of the treatment. Based on the numerical simulations performed, the application of the three types of therapy provided the greatest reduction (99%) in the concentration of tumour cells but also provided a significant reduction (68%) in the concentration of immune cells in the body.","PeriodicalId":300313,"journal":{"name":"Kubik: Jurnal Publikasi Ilmiah Matematika","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139234931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After the graduation process, it was found that the Heligman-Pollard method was the most suitable. This is based on the chart produced using this method, which is monotonous in nature and does not fluctuate like other graduation methods.
