The emergence of antibiotic-resistant bacteria is one of the most serious public health problems. These bacteria develop a defense mechanism against antibiotics, often called immune. In this study, the authors propose a mathematical model that describes the dynamics of sensitive staphylococcus aerus bacteria infected by ciprofloxacin antibiotics, resistant staphylococcus aerus bacteria, and immune cells assuming that the resistance is obtained from the mutations of sensitive bacteria exposed to antibiotic exposure. Qualitative analysis found a balance of the number of bacteria produced by sensitive bacteria that survive the effects of antibiotics and immune cells is less than the number of bacteria produced by resistant bacteria where resistant bacteria would coexist with immune cells in a person's body. The results of this analysis show the fact that when a person's immune system weakens, there is a higher chance of being infected. So, the parameter that can be controlled to suppress the population of resistant bacteria is the effectiveness level of immune cell response to bacteria, this result is supported by numerical simulations performed on the model.Keywords: Antibiotic, Bacterial Resistance, Equilibrium Points, Immune System, Ordinary Diﬀerential Equations Systems, Stability.AbstrakMunculnya bakteri yang resisten atau kebal terhadap antibiotik menjadi salah satu masalah kesehatan masyarakat paling serius. Dalam penelitian ini, dikaji model matematika yang menggambarkan dinamika bakteri Staphylococcus aerus sensitif yang terpapar antibiotik ciprofloxacin, bakteri Staphylococcus aerus resisten, dan sel imun dengan anggapan bahwa resistensi diperoleh dari mutasi bakteri sensitif terkena paparan antibiotik. Analisis kualitatif menemukan adanya keseimbangan saat jumlah bakteri yang diproduksi oleh bakteri sensitif yang bertahan terhadap efek antibiotik dan sel imun kurang dari produksi bakteri resisten di mana bakteri resisten akan hidup beriringan dengan sel imun di dalam tubuh seseorang. Hasil dari analisis ini menunjukan fakta bahwa ketika sistem imun tubuh seseorang melemah, maka peluang terinfeksi lebih tinggi. Jadi, parameter yang dapat dikontrol untuk menekan populasi bakteri resisten adalah tingkat efektivitas respon sel imun terhadap bakteri, didukung oleh simulasi numerik yang dilakukan pada model.

Geometry is one branch of mathematics that is important for students to learn because it can develop problem-solving skills. However, there are still errors in solving problems related to geometry, one of which is the topic of a solid geometry. This study aims to conduct a literature review related to student errors in solving problems on the topic of solid geometry. The research method used is Systematic Literature Review (SLR). Data collection techniques were carried out by documenting and reviewing 43 nationally indexed articles obtained from Google Scholar, then grouped into several categories. 17 articles discuss students' errors on the topic of a solid geometry. Based on the results of the study, it was found that there were still errors in solving problems related to the solid geometry made by students, especially conceptual errors. This is due to a lack of understanding of the concept and the selection of an incorrect formula in solving the problem of solid geometry.Geometri ialah salah satu cabang pelajaran matematika yang penting dipelajari oleh siswa sebab dapat mengembangkan keterampilan pemecahan masalah.

X-Ray Diffraction (XRD) has been developed to analyze a crystal structure in the material. XRD is then improved for determining and identifying the presence of a compound, crystallinity, and crystal properties. XRD works by observing the ray refraction pattern as a result of the beam being refracted by a material that has an atomic arrangement in its crystal lattice. Until now, there is less information regarding detailed information on how to read the XRD spectrum and peak. This study aims to demonstrate how to calculate and interpret the crystallite size based on the XRD spectra. The step-by-step method in the calculation based on the XRD data is presented, which can help especially students and first-time users in understanding XRD results. This study is prospective to be used as standard information on how to read and interpret XRD spectra.
