Abstract

Pest in agriculture can raise plant disease and fail to harvest. The pest problem in agriculture can be solved by using pesticide. Pesticide usage must be done proportionally. So, the manufacturer should fix standard pesticide active ingredient in pesticide production. Forecast is a prediction of some future evens. In forecast problem, there are any parameters which should be determined. Parameters can be estimated by exact method or heuristic method. Ant Colony Optimization (ACO) is inspired from the cooperative behavior of ant colonies, which can find the shortest path from their nest to a food source. In this research, we use heuristic method like ACO to estimate exponential smoothing parameter on pesticide active ingredient forecast and pesticide sample weight forecast. From the simulation, on the first iteration, all ants choose parameter randomly. At the optimization process, we update pheromone until all ants choose the similar parameter so that process converges and variance approaches to zero. The optimal exponential smoothing parameter can be applied in forecasting with minimum sum of squared error (SSE).

Abstract

Predator-prey adalah model matematika yang menggambarkan perilaku interaksi dua spesies, satu diantaranya merupakan pemangsa dan satu lainnya sebagai mangsa. Populasi pemangsa biasanya berada di level lebih atas dibandingkan level mangsa pada rantai makanan. Oleh karena itu, populasi pemangsa lebih sedikit dan rentan akan kepunahan baik karena penyakit ataupun kalah persaingan. Pada artikel ini, dikembangkan model predator-prey dengan dua jenis pemangsa dan salah satunya terinfeksi penyakit. Untuk mencegah penyebaran, diberikan tindakan vaksinasi dan pengobatan yang dirumuskan menggunakan Pontryagin Minimum Principle (PMP). Analisis kestabilan dilakukan secara lokal untuk menunjukkan tindakan vaksinasi dan pengobatan berpengaruh terhadap sifat kestabilan. Terakhir, simulasi dilakukan secara numerik guna melihat perilaku model dan performa vaksinasi dan treatment yang diberikan
