Metode Box-Jenkins menggunakan variabel terikat data dimasa lalu tanpa melihat data tersebut stasioner ataupun tidak. Penelitian ini menggunakan metode Box-Jenkins yang bertujuan untuk meramalkan banyaknya air bersih yang disalurkan PDAM di Pekanbaru. Data yang digunakan dalam penelitian ini adalah data air bersih yang disalurkan PDAM di Pekanbaru. Hasil yang diperoleh dari penelitian ini yakni model yang sesuai untuk meramalkan data air bersih yang disalurkan PDAM di Pekanbaru adalah ARIMA(1,1,1) merupakan model yang sesuai untuk meramalkan dengan nilai MAPE 4%. Dengan hasil peramalan untuk kebutuhan air bersih di Pekanbaru dari bulan Januari 2022 sampai dengan Desember 2023 mengalami kenaikan setiap bulannya. Seiring dengan meningkatnya laju pertumbuhan penduduk di Pekanbaru kebutuhan air bersih pun meningkat sesuai dengan kebutuhan, selain itu struktur tanah yang mayoritas gambut dan kualias air yang berwarna dan berminyak juga mempengaruhi hasil peramalan kebutuhan air bersih di Pekanbaru.","PeriodicalId":403832,"journal":{"name":"Jurnal Sains Matematika dan Statistika","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130116756","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}

The HDI explains how the population can access development outcomes in terms of income, health and education. This study aims to obtain HDI modeling and see what factors affect HDI in Indonesia in 2020. The data in this study are secondary data obtained from the Central Statistics Agency (CSA). Modeling using linear regression is not necessarily suitable to be applied in all provinces in Indonesia are different. Therefore, in this study, a geographical approach was used, namely Geographically Weighted Regression (GWR) in modeling the HDI using the independent variables namely Expected Length of School (ELS), Average Length of School (ALS), Life Expectancy (LE) and Per Capita Expenditure (PCE). The GWR model is a development of the spatial regression model where each parameter is calculated for each observation location so that each location will have a different interpretations. GWR modeling requires a weighting function, while the weighting function used in this study ia the Adaptive Kernel Gaussian. The result of this study indicate that all independent variables affect HDI. The GWR model is the best compared to linear regression with the standard selection of the largest value and smallest value.","PeriodicalId":403832,"journal":{"name":"Jurnal Sains Matematika dan Statistika","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114802505","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}

Pertumbuhan model predator-prey yang dianalisis mengadopsi pertumbuhan logistik. Sementara pada fungsi pemangsaan mengikuti model Holling Type II. Variabel yang tidak kalah penting dalam penelitian ini adalah adanya sumber alternatif bagi predator. Konsep seperti ini sangat realistis untuk dipertimbangkan, mengingat banyak spesies predator yang berganti sumber makanan, dikarenakan sumber makanan yang terbatas. Analisis kestabilan dilakukan pada model untuk melihat keberlangsungan populasi dalam jangka waktu yang lama dengan tingkat interaksi yang sesuai. Dari empat titik equilibrium non-negatif yang dihasilkan pada model, pengujian kestabilan hanya dilakukan pada Abstract This study examines a modified Holling-Tonner predator-prey model of population growth. The growth of the predator-prey model analyzed adopts logistic growth. Meanwhile, the response function follows the Holling Type II. Another important variable in this study is the existence of alternative sources for predators. Such a concept is very realistic to consider, considering that many species of predator change food sources, due to limited food sources. Stability analysis is carried out on the model to see the sustainability of the population over a long period of time with the appropriate level of interaction. The four non-negative equilibrium points generated in the model, stability testing is only carried out at one equilibrium point. The Routh-Hurwitz test was carried out, with the corresponding Jacobian matrix. Numerical simulation becomes the initial realistic assumption for the survival of each species and looks at the character of each species. The chosen equilibrium point is a test of the stability of asymptotic locally and trajectories. The possibility of a transfer of food sources is very possible, while the interaction of cannibalism in the developed model does not have a significant effect on each species.","PeriodicalId":403832,"journal":{"name":"Jurnal Sains Matematika dan Statistika","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131306476","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}
