2023-07-04T23:10:48+08:00

A tobacco oven is a building measuring 4.5 x 4.5 meters that are used to bake freshly harvested tobacco leaves and can accommodate up to 5-7 shelves. The oven building is equipped with 2 bottom vents and 2 top vents that function as temperature and humidity regulators by opening or closing the vents. Tobacco oven techniques in Lombok itself can not be said to be safe, it is proven that fires in tobacco ovens often occur lately. One of the causes of tobacco oven fires is due to the presence of tobacco leaves that fall into the furnace so that the fire quickly grabs the tobacco in a semi-dry state, in addition, due to the lack of use of safety equipment above the ignition furnace, the fallen dried tobacco leaves can immediately burn. Based on these problems, research entitled "Design of Fire Early Detection System in Tobacco Oven Based on Internet Of Things was made (Case Study: East Landah Praya Village)". The system built shows the ability of the infrared fire sensor to detect the presence of fire up to 77.7% at a large fire intensity, the MQ-135 smoke sensor is set at more than 3 ppm as an indication of a fire and the DHT22 temperature sensor shows 1.5% error after comparison with a thermometer. in a tobacco oven.

Today the development of software technology in the field of accounting is increase rapidly following the trend of using mobile devices and the increasing number of new business actors. Prior to this research, we proposed an Accounting Information System (AIS) that runs on a web platform as the main server. The development of this mobile application also uses the same database as the web version running on a dual-platform, web server and mobile based. The Application Programming Interface (API) was developed on the AIS system with the RESTFul method as an integration medium using the HTTP Hyper-Text Transfer Protocol protocol between web and mobile bases in a case study of a company's transaction data. Furthermore, techniques for using the API have described on the development side of the mobile interface. Communication in HTTP is centered on the request response cycle, where the request is the process of requesting data from the server and the response is the data sent by the server according to the client's request. Based on testing the integration process, the information displayed on the mobile version of the application can work properly. Likewise, testing was carried out by entering transaction data into the system as many as 798 records with 141 account lists provided.

As a result, the display of the mobile page shows that all features are able to work and display the same output data as AIS on the web version, including features for reports on purchases and sales of goods, cash flow, general ledger, trial balance, and income statement.

indicators using the K-Means method. The data and parameters used are based on a portrait of education statistics in Indonesia in 2020. This study shows that clustering produces the best cluster quality at K=3 based on the Silhouette Coefficient

Classification of Natural Disaster Reports from Social Media using K-Means SMOTE and Multinomial Naïve Bayes

2023-07-04T23:14:56+08:00

Disasters can occur anytime and anywhere. Floods and forest fires are two types of disasters that occur in Indonesia. South Kalimantan Province is an area that frequently experiences floods and forest fires. The dataset used for previous research's flood and forest fire disaster data is unbalanced. Unbalanced data conditions can complicate the classification method in carrying out the classification process. The sampling method for the data level approach that can be used to solve imbalance problems is oversampling, one of the derivatives of oversampling, namely SMOTE. The K-Means SMOTE method is a modification of SMOTE. One Naïve Bayes model often used in text classification is Multinomial Naïve Bayes. Multinomial Naïve Bayes has a good performance in classifying text. The research results on flood disaster data using K-Means SMOTE with Multinomial Naïve Bayes yielded an f1 score of 66.04%, and forest fire disaster data using K-Means SMOTE with Multinomial Naïve Bayes produced an f1 score of 66.31%.
