The use of interpolation techniques can be applied to inventory problems where some data cannot be determined with certainty. This study aims to determine the optimal amount of rice stock at the Regional Bureau of Logistics Bureau of South Sumatra & Babel using the Economic Order Quantity (EOQ) model and the application of Lagrange interpolation techniques and fractal interpolation. Based on ri…
The study of determines the optimal location of hospitals with Emergency Room (ER) facilities to be visited by people in Palembang City using the Technique For Order Preference By Similarity To Ideal Solution (TOPSIS) and Preference Selection Index (PSI) methods on the Fuzzy Set Covering Problem (SCP). The use of TOPSIS and PSI methods on Fuzzy SCP is used to resolve the problem of ranking base…
Corn is a high carbohydrate plant that can be used as a staple food. The quality of corn must be considered, unhealthy corn results in less than optimal production results and results in decreased corn production. One of the causes of decreased corn quality is pests and diseases that attack corn plants. To overcome this problem, in the current era we can use computer assistance to classify pest…
This study discusses the problem of determining the optimal location of hospitals that have emergency unit facilities visited in the city of Palembang using the Technique For Order Preference By Similarity To Ideal Solution (TOPSIS) method on the Fuzzy Set Covering Problem (SCP). The Fuzzy SCP model with the TOPSIS method is used to solve the problem of selecting or ranking based on several cri…

Robot technology is experiencing a very rapid progress at this time. Sophisticated robots have replaced manual equipment that requires a lot of human labor, one of which is the use of an arm robot. The arm robot that is made is part of a robot with a prototype scale for practical activities that can replace or directly ease human work. In reality, there are often problems on how to control or c…
The value of pH needs to be set in the hydroponic farming system as well as fish farming and the pH of the water must meet the pH value standard. Setting the pH value can be done by adding a solution of acidic water or alkaline water. The problem is how much acidic or alkaline water volume must be added so that the pH of the observed water is in accordance with the desired pH and how to make th…
The lungs are one of the most important organs in the human body. The risk of diseases such as lung cancer can occur in humans. Prevention efforts need to be done, one of which is by conducting early detection when the risk factors and symptoms of cancer have been recognized. One of the early detection methods that can be used is the Fuzzy Sugeno Hierarchy Model method. Fuzzy Logic Algorithm is…
