<![CDATA[UMKM is short for Micro, Small and Medium Enterprises. MSME is a productive business that stands alone, whether carried out by individuals or business entities that do not choose a company. SMEs are distinguished based on each type of business, namely micro, small and medium enterprises. The provision of MSME assistance is one of the problems faced by the Office of Cooperatives, UMKM, Industry and Trade of Muaro Bungo in determining who is truly entitled to receive MSME assistance. One of the main problem factors that inhibits the development of MSMEs to become more advanced is limited capital. Based on these problems, it is necessary to have a Decision Support System (DSS) that can overcome these problems by using the Profile Matching method. SPK is the implementation of an information system that is intended to assist leaders in the decision-making process. The profile matching method is a method that compares the actual data value of a profile to be assessed with the expected profile value selected to be applied to a decision support system for determining the eligibility of MSMEs. This method is used as a criterion for rating MSME support in Muaro Bungo. Which has the final result in the form of a ranking obtained from the calculation of the SMART method, namely An Nisaa UKM selected as an alternative based on the sample data obtained, is eligible for MSME assistance in Muaro Bungo. The aim of the research is that the cooperative office can distribute assistance to business actors who really deserve it, so that with a web-based decision support system it determines the eligibility of recipients of MSME assistance according to and objectively.]]>

<![CDATA[Health is very important for humans, people who don't take care of their health can trigger diseases. Currently, diseases that are not given enough attention are skin diseases, one of which is scabies . Scabies is a disease caused by the mite Sarcoptes scabies which is characterized by scabs and itching of the skin. Scabies disease is easily spread either directly or indirectly. At present, people do not really care about scabies because scabies has symptoms that are just ordinary itching, this happens due to the lack of public knowledge about scabies. To obtain a diagnosis of scabies, you can usually consult a doctor, but due to the limited time for consulting a doctor, there are often problems that make it difficult to obtain information on a diagnosis of scabies. Therefore an expert system was designed to find out and get information quickly about the symptoms that are felt associated with scabies. The method used in expert systems is Case Based Reasoning (CBR). The CBR method is to solve problems by recalling the same or similar events (similarities) that have occurred in the past and then using knowledge or information. This expert system can provide solutions for scabies with the diagnosis process being carried out efficiently and saving time. This web-based expert system application was built using the PHP and MySQL programming languages]]>

<![CDATA[Speed and accuracy in work will be the key to the success of a company in providing satisfaction to its customers. The decision support system is also an interactive system that supports decisions in the decision-making process through alternatives obtained from the results of data processing, information and model design. Kadai Tangkelek Padang is a clothing business in West Sumatra that is well known to many tourists as souvenirs from West Sumatra, not only marketing clothes, they also sell other products such as bags and sandals, what happens is that the evaluation of the feasibility of a product is still done manually , so that feasibility calculations tend to be subjective and require a relatively long time. The purpose of this research is to assist companies in calculating product feasibility at Tangkelek Padang shops using the Weighted Product (WP) method. The Weighted Product (WP) method is a decision-making method by means of multiplication to link attribute ratings, where each attribute's rating must be raised to the first power of the attribute's weight. The result of this research is the creation of a system that can assist in the product feasibility decision-making process at the Tangkelek Padang Store, so that the final result of the calculation can determine whether the product is feasible or not suitable for distribution]]>
