Abstract

LPG is a liquidated natural fuel, often used in the industrial sector and also a necessity that facilitates the household environment sector, in the household itself we can not be separated from the use of LPG gas fuel (liquefied petroleum gas) inseparable from it also the use of LPG in the household sector and even the industry is very much, and that becomes a negative impact that arises as examples often we find in the media the existence of fires due to gas leaks, even we are not aware of a gas leak when we install gas on the switch so it is very dangerous when there is a fire trigger, Therefore, researchers designed an LPG gas leak detection tool via SMS Gateway using an Arduino uno based MQ2 sensor. This researcher designed a tool that serves to detect gas leaks and when there is a gas leak the tool will send a message to Whatsapp with the aim when the user is not in the area around the house or away from the use of gas then the tool will provide notification in the from of Whatsapp messages.

Abstract

Sales can be said to be the center of the business in the field of marketing, in order to get more profit to continue the business. A good company certainly has long-term goals so that it can experience positive developments in the future. With the rapid development of businesses around the world, not a few businesses are built to get more profits with various forms of sales activities. One of the efforts to maintain business stability is to generate sales predictions. The problem faced by the business world today is that there is often an imbalance between supply and demand for goods. The number of buyers and the variety of tastes in the products they have make it difficult for PT Bhakti Bumi Barelang to predict the best-selling items so that they can predict when these items will run out. To overcome this, a vegetable sales prediction system with the highest consumer demand is needed. This prediction will be very helpful for helping vegetable stock supplies such as PT Bhakti Bumi Barelang which plans vegetable stock supplies and informs companies about the products that are most purchased by consumers.

Abstract

This study is to determine OEE in print shops company where company could not get good OEE value in 6 month period, peak OEE value from Jan to Jun 2020 is still low 85% more than the world leading standard. The lowest OEE percentage was in May at 19.92%, while the highest OEE value was in February at 91.19%. The OEE value indicates that the effective level of the printer's process performance is still low. The opposite is true for the substandard operating performance value, namely 68.07%. However, in February the efficiency value reached 87.05%, six major losses being a common factor that can lead to underperformance of the engine. In general, the six factors are breakdown loss, loss of setup and adjustment, small loss and stop loss, speed loss reduction, recovery loss and scrap loss. Equipment failure loss .99%, configuration and adjustment value loss 1%, small stop and stop loss 37.18%, speed loss reduction 3.28%, fault loss 0 ,60%, productivity is reduced by 0% because defective products are not di carded but will be reworked. As a result, data analysis and processing can use Pareto charts to help identify the cause of the biggest losses. According to the Pareto chart made, the six largest loss values ​​are idling and small stopping of 37.18% and reduction of speed loss, with a start-up result of 3.28%. Thus, the company can pay attention to the needs of the machine to be able to meet the needs of large-scale production.

Abstract

Weather is also an important factor in supporting human activities, especially in Indonesia. Human activities that are highly dependent on weather conditions include flight activities, shipping, land travel, agriculture, companies that use the sun as a dryer for their production materials, daily activities (drying cloth). Every day, BMKG Indonesia as an institution engaged in Meteorology, Climatology, Air Quality and Geophysics is tasked with providing information on weather forecasts in Indonesia based on available data. However, at this time it is very difficult to predict the weather conditions because of rapidly changing climate conditions resulting in irregular season changes. Weather conditions are influenced by interrelated elements, namely temperature, humidity, air pressure and the intensity of sunlight. Erratic weather changes can only occur for a few hours and differ in various regions (Puspita, 2016). Fuzzy logic is a level of Boolean logic that deals with the concept of partial truth. Where fuzzy logic maps an input space into an output space by using IF- THEN rules. With the help of the application of Fuzzy logic, this research has the aim of processing the data obtained from temperature, air, and air pressure using Sugeno's fuzzy logic and testing accuracy using MATLAB.

Abstract

Clinics are places or facilities for providing information on drugs and other pharmaceutical supplies to the public. This resulted in uncertain results from sales at the clinic. Types of drugs that are increasingly varied, from drugs that are cheap to prices that if you look at it don't make sense but have very good functions, especially in the distribution of types of drugs. To overcome this problem, the classification of drugs that are sold or not sold at the clinic is based on the variables obtained using the Naive Bayes Agorithm which is able to provide information about the existing products in the clinic and minimize the stock that accumulates for the unsold category. The availability of a lot of data in an area of ​​need for information becomes a reference in making decisions to make business solutions. The desired information in this study is to obtain an accuracy value for the sales data for these drugs, which are often an option. This research uses Rapidminner tools as a medium for testing data to be processed to obtain an ROC (Rank Order Centroid) value of 80% accuracy based on the importance or priority of the criteria.
