Abstract

TikTok addiction among high school students in Lampung Province is very worrying. This study aims to identify and understand the spread model of TikTok addiction as well as analyze the equilibrium stability of the model. The subjects of this research are high school students in Lampung Province. The research sample consists of 90 students, with details of 63 females and 27 males, who were randomly selected from the population of high school students in Lampung Province. The first step is to build a mathematical model based on assumptions related to the  models, as well as the characteristics of addiction. From this, diagrams and mathematical models in differential equations are formed. Next, the researcher will calculate the basic reproductive value and determine the addiction-free and endemic equilibrium points based on a pre-built model. The next stage is to analyze the stability of these equilibrium points. Ultimately, the simulation will be carried out using the  model program by entering the initial values and parameters set. Based on the research results, a building model of Tiktopk addiction was obtained, namely , , , , , , with . Based on the results of the analysis, it was found that the basic reproductive number () of social media addiction among students reached 1.02. This indicates that, on average, one student who is already addicted can spread his addiction to one to two other vulnerable students in the sample population studied. The number of students in each compartment initially has an upward graph, gradually decreasing over time, and is in equilibrium. Based on the study's results, it was found that the equilibrium points of the differential equation describing the mathematical model are stable.

Abstract

Educational supervision in schools plays an important role in maintaining and improving the overall quality of education. The quality of education is determined by various factors, one of which is the role of teachers. This study aims to explore the role of teacher supervision in learning quality. This research uses a descriptive qualitative method, so it is necessary to conduct observations and interviews in one of the public junior high schools in Central Lampung District. The result obtained from this research is that the role of teacher supervision is very important in improving the quality of learning in schools. Supervision that is carried out in a planned and data-based manner has a positive impact on the capacity development of teachers and principals. Various challenges faced in implementing supervision, such as managerial busyness, lack of preparation from teachers, and limited facilities, can be overcome with improved coordination, more careful planning, and the use of technology to support the supervision process. This teacher supervision is seen in the improvement of learning quality, more effective education management, and better achievement of educational goals. Thus, teacher supervision plays an essential role in creating a quality and sustainable learning environment.
