Amylase is one of the most essential enzymes that have potentially widely used in various industrial fields such as food, fermentation, and pharmacy. Amylase can be obtained from diversified organisms such as plants, animals and microbes. However, the main sources of these enzymes are bacteria and fungi that have dominated utilization in industrial sectors. This study was aimed to obtain the potential for amylolytic lactic acid bacteria (LAB) isolated from pliek u Acehnese traditional food. Amylolytic LABs were isolated with starch plate method and tested with Lugol's iodine reagent to measured the amylolytic index. The isolation results showed that 5 amylolytic potential LAB isolates were found with cells morphological characters were bacilli, Gram positive and motile. Amylolytic index of five isolates were varied, the highest index was found in UKA5 isolate which was 11 mm while the lowest was found in UKA2 isolate which was 7 mm.

Red galangal is a plant that belongs to the Zingiberaceae group that can live in the highlands and lowlands. Red galangal has chemical properties namely flavonoids, phenols, terpenoids, tannins which can be used as a treatment for skin diseases such as scabies, tinea versicolor, ringworm and burns which are often caused by Staphylococcus aureus bacteria. This study aims to determine the inhibition of red galangal juice on the growth of Staphylococcus aureus. This study uses an experimental method using the disc diffusion method. The sampling technique uses a purposive sampling technique. The sample used in this study was the extract of red galangal rhizome. The results showed that red ginger juice could inhibit the growth of Staphylococcus aureus at a concentration of 60% obtained by inhibition zones 13.88, 80% concentrations obtained by inhibition zones 16.5 and 100% concentrations obtained by inhibition zones 18.33 mm and included in the category.

As technology develops, a system that is capable of adopting human processes and ways of thinking is developed, an expert system that contains certain knowledge so that everyone can use it to solve specific problems, namely the problem of diagnosing cholera. Cholera is an acute diarrheal disease which in a few hours can cause rapid and severe progressive dehydration and can cause death caused by the bacterium Vibrio Cholerae. The purpose of this research is to build an expert system to diagnose cholera in order to be able to do prevention and treatment early. The expert system to diagnose cholera using a hybrid case based method aims to trace the symptoms displayed in the form of questions in order to diagnose the type of illness. This expert system is able to recognize the type of cholera after consultation by answering several questions raised by the application of the expert system and can conclude several types of diseases suffered by the patient. The recognized disease data adjusts the rules that are made to match the symptoms of cholera. The design of this application is made with the PHP programming language and MySQL database. Through this application, every person especially those who live in remote areas with limited number of doctors at the public health center are expected to be able to diagnose cholera, so that it is likely to be prevented and treated quickly.

Health is a valuable thing for humans, because anyone can experience health problems. Society is a layman who does not understand health problems. If there is a health disturbance to them then they are more entrusted to the expert or expert doctor. In this case, the community as service users more need an expert who can make it easier to diagnose the disease early in order to be able to take precautions early which would require time if consulting with a specialist. Because of this, we need a tool that can diagnose diseases in the form of an expert system. Bayes method is a method used to calculate the uncertainty of data into definite data by comparing yes and no. Certainty factor is a method to prove whether a fact is certain or uncertain in the metric form that is usually used in expert systems. Expert system is a system that is able to mimic the reasoning of an expert so that computers can solve problems as is usually done by experts. Knowledge stored in expert systems is generally taken from a human expert in the matter. The important role of an expert can be replaced by a computer program which in principle works to provide a definite solution as is usually done by an expert. For this reason, a system was built by designing an expert system to diagnose varicella disease in children by applying the Certainty Factor and Bayes Method in visual studio 2008 which is used for consultation, analysis, diagnosis and to help make decisions.
