Abstract

This paper presents a method of finding a continuous, real-valued, function of two variables z = u(x, y) defined on the square S := [0,1]2 , which minimizes an energy integral of fractional order, subject to the condition u(0, y) = u(1, y) = u(x,0) = u(x,1) = 0 and u(xi ,yj)=c𝑖𝑗 , where 0<x1<...<xM,<1, 0<y1<...<yN<1, and c𝑖𝑗 ∈ ℝ are given. The function is expressed as a double Fourier sine series, and an iterative procedure to obtain the function will be presented.

Abstract

West Sulawesi has the second highest stunting rate after East Nusa Tenggara, various efforts continue to be carried out by local governments and universities in West Sulawesi such as UNSULBAR. This service activity aims to increase the consumption of animal protein by processing livestock products, especially broiler chickens with the diversification of processed foods that are favored by children and adults such as processed meatballs and nuggets. The ingredients used to make the meatballs are broiler chicken with tapioca flour, eggs, pepper, while the nuget is made from broiler chicken with chicken eggs, bread flour, wheat flour, garlic, powdered broth, salt, sugar, and pepper. The manufacture of meatballs and nuggets begins with the provision of raw materials, refining chicken meat, adding spices and boiling the meatballs, while the nuget begins with refining chicken meat, mixing spices and meat, steaming nuggets, smearing nuget in bread flour and then frying the nuggets. Based on the results of these activities, it can be concluded that through food diversification, turning chicken meat into a delicious and nutritious food item has succeeded in increasing participants' knowledge by 30%. Keywords: chicken meat, frozen food, meatballs, nuggets, stunting
