Riau is a province that has many oil palm plantations. One of the industries that manages palm oil is PT. Tasma Puja having the address jl. The kuamang river, kampar, where it produces crude oil or vegetable oils and animal oils. To calculate the quality of palm oil at PT. Tasma Puja is carried out laboratory tests based on water and dirt content, free fatty acid content, color and peroxide number. The process of storing free fatty acid data produced every time the production from laboratory test results is still stored manually using the Microsoft Excel application. By storing these data, there are weaknesses, namely the difficulty in assessing the quality of palm oil production produced. This study was conducted to better analyze and store production data from PT. Tasma Puja. The results of this study will be able to provide benefits to PT. Tasma Pujasehing will later facilitate PT. Tasma Puja in storing and processing palm oil production data. Analysis of these problems uses the concept of decision support systems Analytical Hierarchy Process (AHP) method which is supported by PHP programming applications.

The purpose of this study is to apply fuzzy logic to predict the amount of Palm Kernel Oil (PKO) production at PT. Web-based AAI. This study uses the Tsukamoto method to anticipate the instability of palm oil production based on the existing demand and supply. The results showed that with the implementation of the fuzzy logic, the Tsukamoto method can affect the rate of more stable production and reduce the production of which is not in accordance with the market demand. The conclusion of this study is to apply the result of the predicted number of production PKO (Palm Kernel Oil) at PT AAI, in order to know the budget supply and demand thereafter.

Expert system is a computer program which is designed for modelling the ability of problem solving as it is an expert (human expert). The expert system method used is the forward chaining method which is the inference method that is doing logical reasoning from the problem to its solution. The aim of this research is to design and develop an expert system that is able to identify the severe malnutrition on children from the age of 0 - 5 years old. The knowledge is derived from the question askedto a nutrition expert. The data are taken from the questions asked to the user and when all of the questions has been answered, then the goal will be appeared which shows the nutrition status. This system application will enable the user to diagnose the nutrition/disease that affects children and get the solution. This system can be used by any kind of user due to the easy access. This system is also put the important information about the severe malnutrition and the recent news of children’s health so it will add more knowledge for the parents about the importance of severe malnutrition’s prevention.
