Abstract

One of the causes of the large number of forest and land fires in Riau Province is human intent to divert forest functions, so that hotspots appear in areas that have the potential for forest and land fires. The purpose of this study was to simulate forest and land fires that occurred in Riau Province using Cellular Automata by utilizing satellite imagery. Land in Riau Province is divided into 5 states, namely: dry land, wet land, land that is being burned, land that has been burned, and land of water. The method used for simulating forest fires is the Cellular Automata to simulate the movement of fire during a fire. This method is able to explain the pattern of fire spread of the main cell fire from neighboring cells. At the end of the study, the simulation results and the movement of fire from where the hotspots appear on satellite images of Riau Province will be shown according to the state of the land cover. The results of this study are a description of the real situation of fires that occurred in Riau Province based on the emergence of hotspots and their movement patterns.

Abstract

One of the social problems that is still controversial is smoking. This is closely related to public health, because smokers have a great risk of spreading disease either directly to smokers themselves or indirectly to other people who do not smoke but are in the same environment or population as smokers, such as cancer, heart disease. , caries, and others caused by the substance content of the smoked cigarettes. The more smokers in a population, the greater the chance of increasing the number of smokers in that population, which directly or indirectly means increasing the spread of the diseases that have been mentioned. The purpose of this research is to construct a mathematical model and simulate the distribution of smokers in a certain population using Matlab. The variables that make up the Mathematical model are divided into 3 classes, namely prospective smokers (), regular smokers (), and ex-smokers (). The method used in this research is the method of literature study and literature related to research and simulation using Matlab. At the end of the study, the value of the basic reproduction number () will be analyzed to determine the dynamics that occur in the population and the simulation results of the mathematical model formed. The results of this study are a depiction of how much influence the presence of smokers has in a population by looking at the parameters that affect changes in the value significantly.

Abstract

Ketidakstabilan harga merupakan salah satu masalah penting dalam pemenuhan kebutuhan pangan masyarakat Indonesia. Perlu upaya dalam mengambil keputusan yang lebih baik guna memprediksi ketidakpastian masa depan, salah satunya dengan metode peramalan. Tujuan penelitian ini adalah untuk meramalkan harga bahan pangan di waktu akan datang menggunakan Fuzzy Time Series yang dikembangkan oleh Chen (1996). Peramalan menggunakan data historis bahan pangan (beras, minyak goreng, gula pasir, ayam potong, daging sapi, dan telur ayam ras) periode Januari 2019 – November 2023, kemudian diubah menjadi nilai linguistik agar nilai permalan yang diperoleh lebih akurat. Hasil peramalan harga bahan pangan (beras medium, minyak goreng premium, gula pasir, ayam potong, daging sapi, dan telur ayam ras) pada periode selanjutnyaberturut-turut (dalam rupiah/ kg) adalah  14907,80273; 16844,40540; 16073,89574; 35583,30727; 136038,4927; 30302,34563. Sedangkan tingkat keakuratan prediksi harga bahan pangan dengan metode MAPE, diperoleh bahwa semuanya akurat. Dengan adanya hasil peramalan ini, dapat dijadikan salah satu pertimbangan dalam menentukan kebijakan oleh pihak berwenang guna mencukupi kebutuhan pangan masyarakat Indonesia.
