Abstract

Smoking is the activity of burning tobacco then sucking the smoke and releasing it back through the mouth. This study examines the spread of smoking behavior based on economic factors and psychological factors. This model divides the population into 4 subpopulations, namely potential smoker , Beginner smoker , Smoker subpopulation and recovery subpopulation The stability of the smoking-free equilibrium point is obtained by linearizing the equation to obtain the Jacobian matrix and then the eigenvalues will be obtained. The basic reproduction number which is the threshold for the spread of smoking behavior where smoking behavior will disappear if Ro < 1 and will be endemic when Ro > 1.

Abstract

Demam Berdarah Dengue (DBD) menjadi salah satu masalah kesehatan masyarakat di Indonesia yang masih membutuhkan penanganan hingga saat ini. Salah satunya yakni memberantas larva nyamuk DBD memakai larvasida. Penelitian ini membahas mengenai model penyebaran penyakit DBD tipe SIR, kelompok populasi manusia (host) dipilah menjadi tiga kelas, yaitu Susceptible, Infected, dan Recovered, sedangkan populasi nyamuk (vektor) juga dalam tiga kelas, yakni ASI (Aquatic, Susceptible, dan Infected). Selanjutnya dari model ditentukan titik kesetimbangan, bilangan reproduksi dasar, analisis kestabilan terhadap titik kesetimbangan bebas penyakit dan simulasi. Hasil analisis menunjukkan bahwa pada kondisi ℛ0 < 1 titik kesetimbangan tanpa penyakit stabil asimtotik. Hasil simulasi pengaruh penggunaan larvasida terhadap penyebaran penyakit DBD juga menunjukkan bahwa semakin meningkatnya jumlah kematian larva karena pengaruh penggunaan larvasida menyebabkan bilangan reproduksi dasar semakin menurun bahkan sangat kecil sehingga hal ini dapat membantu menekan laju penyebaran penyakit DBD tersebut dalam populasi.

Abstract

Given that most of the people of Maikang Village think that the more children in a family, the income from candlenut plantations will also increase, so this study aims to determine the Effect of the Number of Children on Candlenut Plantation Income in Maikang Village, Alor Selatan District in 2020. The Chi-Square method is a hypothesis test comparing the frequency of observations that occur or occur with the frequency of expectations or expectations. From the results of this study, it is known that the calculated Chi-squared = 8.1890 and the table Chi-squared with dk 1 and an error rate of 10% = 2.706. If you compare count (8.1890) with table (2.706), then 2 count is more than 2 table. This shows that there is an influence between the number of children on the income of candlenut plantations.

Abstract

ABSTRACT Giving credit is a business activity that contains a high risk and affects the sustainability of businesses such as cooperatives and banking. The aims of this research are to: (a) knowing the credit decision making system implemented in KSP Kopdit Swasti Sari, (b) knowing the calculation of the remaining credit payments using the first-order linear difference equation. In this study, the method used to calculate the remaining debt for credit payments is a first-order linear difference equation, namely the remaining debt after the first payment is the same as the remaining debt after payment to t plus interest minus annuity. The results of this study indicate that the credit decision-making process is considered worthy of receiving a credit loan if it meets the requirements that have been set at the KSP Kopdit Swasti Sari. The step to calculate the remaining credit payments using a mathematical model is to find the amount of fixed installments from an ordinary annuity with a different loan size, namely Rp 5.000.000, Rp 10.000.000 and Rp 15.000.000. After getting the results from the ordinary annuity, a mathematical model of the remaining credit payments is formed using equation (2.13). The results of the calculation of the remaining credit payments using a mathematical model are as follows: For the first order linear difference equation with a loan size of Rp 5.000.000 after paying the first installment () the remaining debt is Rp 4.900.081 and the remaining debt () of Rp. 8. For a large loan of Rp. 10.000.000 after paying the first installment () the remaining debt is Rp. 9.800.162 and on payment of () the remaining debt is Rp. 16. For a large loan of Rp 15.000.000 after paying the first installment () the remaining debt is Rp 14.700.243 and on payment of () the remaining debt is Rp 24.

Abstract

TikTok is an entertainment application that can be used to watch and share various short videos such as educational information, dance, fashion, and even promote a product, as well as shop online. If it is used continously, it may provide negative impact. TikTok users may become stressed if it does not meet the creator’s expectations such as getting the most likes or viewers from users. Furthermore, they also can addicted to online shopping and buy something that they do not need due to lost self-control and be unable to consider risks in making decisions resulting in stress or depression. This study aims to build a mathematical model of TikTok addiction Type SEI1I2R. The results of the study obtained two equilibrium points, namely the free equilibrium point for TikTok addiction T1 and be stable when R0 < 1 and the equilibrium point for addiction to TikTok T2 and be stable when R0 > 1. The simulation shows that when R0 <1, even though most of the population have TikTok application, they are not interested in content and shopping via TikTok. This causes the population that creates TikTok accounts decrease and hence the addiction to content and shopping on TikTok slowly decrease and then disappear in the population. Meanwhile, when R0 > 1, many people think that content and shopping on TikTok are very interesting so that the population that creates TikTok accounts is increasing so that there is an increase in the population creating content and shopping on TikTok. Therefore, TikTok addiction will remain in the population and will increase with time.

Abstract

Shopee is an online shopping application that is easy to use with customers' smartphones anytime and anywhere. The presence of Shopee can make it easier for users to shop for goods/services products via smartphones without the need to use a computer. Shopee sells all kinds of needs such as household needs, fashion, watches, cellphones, accessories, beauty, and so on. Without realizing it, Shopee has a negative impact on users who use it continuously so that it becomes a habit / addiction. Online shopping results in waste because shopping is not according to need but desire because it does not have high self-control, resulting in stress or depression. This study aims to build a mathematical model of online shopping addiction in the SEIR type Shopee application. Based on the research results, two equilibrium points are obtained, namely the equilibrium point free of online shopping addiction on the Shopee application and will be stable when and the equilibrium point there is online shopping addiction on the Shopee application and will be stable when . Simulation results are observed in two conditions, namely when , the value of is obtained, meaning that the rate of people interacting with people who are addicted to online shopping at Shopee is still small, causing the rate of groups of people who create accounts to shop and eventually become addicted to online shopping. When , the value of is obtained, meaning that the rate of people interacting with people who are addicted to online shopping in the Shopee application has increased, causing the rate of groups of people who create accounts in the Shopee application and eventually become addicted to shopping online at Shopee to increase over time.
