Abstract

Chandra Talo Building Store is one of the building shops located in Seluma Regency, Bengkulu Province. The store sells various kinds of building materials, from cement, paint, nails, wood, and others. So far, the management of data on materials, starting from recording inventory and selling goods, is still done manually through bookkeeping and notes, because there is no specific application that can help manage this data. The Goods Sales Forecasting Application at the Chandra Talo Building Store is built on an Android basis which can be accessed via an Android smartphone. The Goods Sales Forecasting application at the Chandra Talo Building Store was made in order to assist the Store in determining the amount of building materials to be restocked, by analyzing the time series on building material sales data that occurs every month which will produce a forecast or estimate of the amount of building materials to be restocked. Based on a comparative analysis of the Linear Regression Method and the WeightMovingAverage Method through the MAPE Method and the MSE Method, the results of the Linear Regression Method have a smaller error value than the WeightMovingAverage Method. Based on the system testing that has been done, it can be concluded that the functionality of the goods sales forecasting application at the Android-based Chandra Talo Building Store has been running well and can provide output reports on the results of forecasting sales of goods.

Abstract

So far, the puskesmas has not fully implemented information technology in it, due to the limited facilities and infrastructure used, so that all patients who wish to seek treatment must come more to get a registration number for treatment. This happens because the number of doctors at the puskesmas is not proportional to the number of patients who wish to seek treatment at the puskesmas, so that a limit is imposed on the number of patients seeking treatment every day. The application of an expert system for diagnosing rubeola disease at the Beringin Raya Nursing Health Center in Bengkulu City was created to assist the puskesmas in diagnosing rubeola disease in patients based on the symptoms experienced by the patient. In the process of diagnosis, the expert system application has applied the Certainty Factor Method which is used to obtain the percentage level of certainty for the rubeola disease. The application of an expert system for diagnosing rubeola disease at the Beringin Raya Health Center in Bengkulu City was made using the Visual Basic.Net programming language. Based on the results of the tests that have been carried out, the functional application of the expert system for diagnosing rubeola disease at the Beringin Raya Treatment Health Center in Bengkulu City is running well as expected and can provide information on the results of consultations to determine rubeola disease
