Abstract

Penjadwalan petugas satuan pengamanan merupakan salah satu permasalahan yang sering timbul pada sistem manajemen keamanan pada suatu tempat. Demikian pula manajemen keamanan pada unit keamanan kampus Universitas Negeri Gorontalo. Penjadwalan petugas satuan pengamanan yang tepat diperlukan untuk menghindari kelelahan bagi para petugas, baik fisik maupun psikologis yang dapat menurunkan kinerja para petugas. Dalam penelitian ini, permasalahan penjadwalan satuan pengamanan dimodelkan sebagai Integer Linear Programming (ILP) dengan fungsi objektif Linear, fungsi kendala Linear dan variabel berupa bilangan Integer. Dalam menyelesaikan permasalahan penjadwalan ini, maka akan diselesaikan dengan bantuan software LINGO 11.0. Fungsi objektif model ini adalah memaksimalkan hari kerja petugas satuan pengamanan dalam satu periode penjadwalan dengan 3 kali shift.

Abstract

Drugs have a bad effect on the users which is mental disorders and health problems even causing death. Cases of drug users spread can be formulated with a mathematical approach through the concept of mathematical modeling. This article discusses the mathematical model of SURS type drug users spread. Model development by adding educational factors to each population class. Furthermore, the basic reproduction number () is constructed to model the threshold value of the spread of drug addicts. The basic reproduction number is determined by using a Next Generation Matrix approach. The next step is to do a sensitivity analysis to determine the parameters that most influence the spread of drug addicts. Based on the analysis results, the parameters β and indicate the most dominant sensitivity index to the basic reproduction numbers. At the end of this article, a simulation is carried out to show the effect of changing parameters on the population of drug addicts.

Abstract

Gorontalo Province is one of the provinces in Indonesia where 60% of the population are farmers and fishermen. As much as 28,66% of PDRB in Gorontalo Province in 2020 was contributed by the agricultural sector. Farmer's Exchange Rate is a measurement capability of agricultural products in producing goods or services. Therefore, NTP forecasting is needed so that it becomes a reference in the future in making a decision to increase the agricultural sector. In this study, a comparison was made of the Holt Winters Exponential Smoothing method with Lee's Fuzzy Time Series to find out which is the best forecasting method for predicting NTP in Gorontalo Province. Based on the forecasting results, the accuracy value obtained from FTS Lee has a mape value of 0,65557% for FTS Lee order 1 and 0,55607%. While the accuracy value obtained by the multiplicative Holt Winters Exponential Smoothing is 5.92509% and the additive Holt Winters Exponential Smoothing is 6,14574%. From the forecasting results obtained, it can be concluded that the best method for predicting NTP in Gorontalo Province is the FTS Lee Order 2 method.

Abstract

Let G be a simple and finite graph. Rainbow connection and total rainbow connection c are set c : G → {1,2,. . . , k} where k is the minimal color on graph G. A rainbow connection number(rc) is a pattern by giving different colors to the connection edges (E(G)) so that a rainbow path is formed. The total rainbow connection number (trc) is a payment pattern by giving color to vertices (V(G)) and edges (E(G)) in graph G so that a total rainbow path is formed. This article discusses rainbow connection numbers (rc) and total rainbow connection numbers (trc) in the corona graph of book graph (Bn) and pencil graph (Pcm). The results obtained are rc(Bn ⨀ Pcm) = 2n+3 and trc(Bn ⨀ Pcm) = 4n+5, 3 ≤ n ≤ 5.

Abstract

This article discusses the mathematical model of the spread of COVID-19 by considering vaccination and population migration. The former model is analyzed by determining the equilibrium point, basic reproduction number, analyzing the stability of the equilibrium point, sensitivity analysis, and accompanied by numerical simulation. Analysis of the stability of disease-free and endemic equilibrium points using the Routh-Hurwitz Criteria and the Castillo-Chaves and Song theorems. The results of the analysis show that there are two equilibrium points, namely a disease-free equilibrium point (T1), which is locally asymptotically stable when R0 1, and an endemic equilibrium point (T2), which is locally asymptotically stable when R0 1. Furthermore, the sensitivity analysis showed that the most sensitive parameters to changes in the basic reproduction number were the emigration rate parameter (m2) and the infection probability parameter after contact between infected and susceptible individuals without vaccination (h). In addition, the numerical simulation results show that the sensitive parameter values, namely m2, h, zse, g, and # have a significant effect on the basic reproduction numbers. Suppressing the chance of infection in susceptible individuals and the rate of contact between susceptible and exposed individuals, as well as increasing the number of individuals who emigrate and who are vaccinated, can reduce the transmission of COVID-19.

Abstract

Development is essentially a process of continuous change carried out to achieve better living condition. So that the benchmark for the success of a development is seen in its human development. 3 The basic dimensions that form human development are long and healthy life, knowledge, and a decent life. The indicators that represent the three dimensions are summarized in a single value, namely the Human Development Index (IPM). In 2021 the HDI figure in Indonesia is 72.29, which means it is high. However, due to the diverse geographical location of regions in Indonesia, this also influences the HDI rate in each region in Indonesia, so this study uses the Random Forest Algorithm to obtain accurate results from the HDI classification and uses Forward Selection to determine features that influence the classification. The results of the study show that the features that influence the classification are per capita spending, expected length of schooling, life expectancy, and average length of schooling, and get a final accuracy of 80%.

Abstract

An investment can provide a profit with a certain level of risk for an investor both now and in the future. This indicates that investments are important in both financial and asset management. Finance investments can be made on several stocks or portfolios. To profit from an investment, you need a tool to optimize profit and risk, which is a portfolio. This research uses the Black Litterman Model in portfolio optimization along with Value at Risk (VaR) calculations to determine the risk of each stock. The data used is close price data on the Business Index 27 for the period January-December 2023. Next, selected 9 shares in the formation of an optimal portfolio namely, AKRA, AMRT, ASII, BBCA, BBNI, BBRI, INKP, KLBF and TLKM. Based on the calculations, the rate of profit achieved on the portfolio is 5.48% with a risk of 0.40%. Then use the Historical Method and the Monte Carlo Simulation Method to calculate the VaR using nine optimal stocks, with a 95% confidence rate. In the Monte Carlo simulation, 300 repetitions of VaR calculations are performed. Different results on both methods are due to different approaches to risk calculation
