Linear programming is one of several methods of maximizing or minimizing an objective function to create an optimal solution. However, an efficient method is needed to perform calculations. In this research, the manual simplex method was used to maximize profits from the sale of penyet chicken, geprek chicken and halibut chicken in one of the MSME businesses in the city of Medan. Apart from that, an analysis tool was also used in the form of an application called POM-QM for Windows to verify the calculation results manually. In this research, 3 variables and 7 obstacles were identified which were resolved using the simplex method which means a maximum profit of IDR 2,330,000 per day with an increase of IDR 1,194,000.

In a Micro, Small and Medium Enterprises (MSMEs), business actors often do not know exactly how many goods must be produced and sold in order to get maximum profit. To find out the maximum profit and the number of products that must be produced, the simplex method in linear programming can be used. The simplex method is a method to find the optimal solution of a linear programming model with the principle of iteration. There is a tool to solve linear programs quickly, namely Lingo software that can be used to calculate many problems in a fast time. To implement this simplex method, the data taken by researchers is on MSMEs that produce Cold Drinks with the name Cold Ice. That way, the purpose of this study is to find out how much maximum profit is obtained after obtaining the optimum production amount of each product on Cold Ice in the Medan area.

Consumer market demand for certain specifications of coal continues to increase every year. However, each coal company has a variety of coal qualities in terms of calorific value, water content, ash content, and total sulfur and so on. PT. Alamjaya Bara Pratama is a coal mining company that has several types of coal products that vary in quality. By coal blending, the aim is to obtain coal product that meet the target with a homogeneous composition and according to consumer coal quality specifications. With the linear programming method for coal blending calculations using the Production and Operation Management - Quantitave Methods software has an influence in maximizing the use of the composition quantity for each type of product (MD and HS) as well as optimizing the quality of the coal blending results. Through POM-QM, it has the advantage of being able to determine the benchmark target value for one of the desired coal quality parameters. With subbitumious coal quality as for the research results are calculations of the final quality for each Mother Vessel, one of which is MV Eastern Camelia with the planning results is (AC 5,0% adb, TS 0,90% adb, GAR 4590 kcal/kg arb) with tonnage requirements for coal products (MD = 29.727,84 MT and HS = 22.772,16 MT). Through the use of linear programming (POM-QM) in calculating coal blending planning, the results are obtained and meet each coal quality parameter limit criterion based on consumer demand.

Background: Increasing droughts caused by climate change have significant impacts on the agricultural sector, particularly on household food security. Purposed: To examine farmers' perceptions of the impact of horticultural crop diversification as an adaptation strategy to improve food security in drought-prone areas. Research Method: A quantitative approach using a survey method based on questionnaires distributed to farmers involved in horticultural crop diversification. Household food security was measured using the Household Food Security Index (IKP), and linear regression analysis was used to assess the impact of crop diversification on food security. Results: Horticultural crop diversification can improve household food security, particularly in drought-prone areas. Social, economic, and agricultural resource access factors have a significant impact on food security, with access to agricultural resources having the greatest effect. The validity and reliability tests show that the instruments used in this study are valid and reliable. In addition, the normality, multicollinearity, and heteroscedasticity tests indicate that the data meet the assumptions required for regression analysis. This study concludes that horticultural diversification is an effective adaptation strategy in dealing with the impacts of climate change and improving household food security, with recommendations to increase access to agricultural resources and support crop diversification programs in drought-prone areas.
