Abstract

Online shopping business start-known in Indonesia. Some advantages of online shopping is the marketing of products can reach consumers anywhere, the ease of both payment transactions and goods delivery, competitive pricing, product selection is varied, t he quality of the product can be communicated to consumers more transparent lagi.Tujuan of writing this thesis is to analyze and design website is also an online marketing system on PT. Ratu Enim Gallery so it could help market the products of fuel briquettes as a substitute for kerosene, LPG and charcoal is more efficient, safe, hot and easy to households and industry. The method used is the method of analysis and design methods. Analytical methods used to conduct surveys and questionnaires to PT. Ratu Eni m and consumers in order to get the proper analysis for the design of marketing systems at PT. Ratu Enim. Thus we can find out the advantages and disadvantages of this system. The results obtained from both methods is in the form of a website. Website PT. Ratu Enim serves as a means for the promotion of briquettes which provides various facilities, such facilities briquettes information about products and facilities to accommodate inquiries from consumers.

Abstract

The excess temperature in the inverter will cause a decrease in efficiency. The research of over temperature protection systems on solar power generation inverters using Arduino aims to design an over temperature protection system on PLTS inverters using Arduino so that there is no reduction in efficiency and prevents the inverter components from damage due to heating. The method used is an experimental method that is designing an over temperature protection system on the inverter to get good design results. The equipment used is solar panels, inverters, fan motors, L298N drivers, Arduino and batteries. The results showed that the over temperature protection system equipment on the PLTS inverter using Arduino was able to protect the over heating in the inverter, especially to increase the load from 272 watts to 532 watts with an increase in temperature of only 0.1 0C. For the use of an inverter for a long time, the temperature inside the inverter in the previous state greatly affects the temperature inside the inverter in the next state so that the temperature decrease along with the linear load decrease is difficult to achieve, especially at 630 watts with an inverter temperature of 37.6 0C, some time after that a decrease in load occurs until the load becomes 105 watts but the temperature value in the inverter has a value greater than the 630 watts loading that is equal to 37.9 0C

Abstract

Seawater flood early warning system serves to inform the public of the occurrence of flood events caused by rising sea water. With an early prevention system, the occurrence of sea water floods can reduce the impact or loss caused by tidal floods. This research aims to make a prototype of an early warning system for tidal flooding. Arduino-based systems use ultrasonic sensors to measure sea water levels. The system is also equipped with a buzzer that serves as an alarm to inform the public of a tidal flood. In addition, an early warning for tidal floods will also be delivered to the public through the SMS (Short Message Service) communication media. From the results of the discussion it was found that the early warning system for seawater flooding using two ultrasonic sensors through the SMS communication media works well. The ultrasonic sensor used is able to measure the height (level) of the water surface from 5 cm to 60 cm. The average percentage of measurement error for the first ultrasonic sensor is 1.125% and for the second ultrasonic sensor is 1.515%. The average percentage of measurement error for both sensors is 1.32%. The level of accuracy of system in measuring the height (level) of the water surface is 98.68%.
