Lux meter is a device used to measure the intensity of light in an area. The purpose of this thesis is to design a light intensity measuring device using LDR components as a light sensor, comparing light intensity measuring devices made using LDR sensors and Arduino Leonardo based microcontrollers with standard tools. The data used in this study are primary data. The data obtained is then processed using MS. Excel. The type of light bulbs used are Philips CFL (Philips Essential) lamps, each lamp having a power of 5, 8, 11, 14, 18, 23, 27, 32, 35, and 50 watts with a luxmeter vertical distance of 1, 2 and 3 meters from the lamp. From the results of testing the tools and processing of comparative data between the Lux Meter Standard and the designed Lux ​​Meter obtained as follows: the vertical distance of the tool by 1 meter from the lamp produces an average error difference of 12,571 lx and the percentage of average errors the average is 8.77%, while for the vertical distance of the tool is 2 meters from the lamp the average error difference value is 2,358 lx and the average error percentage is 7.98%, and for the vertical tool distance is 3 meters from the lamp the difference in error value is an average of 0.92 lx and an average error percentage of 5.85%.

This study aims to design a production cost budget at the Teaching Factory for cooking oil, chemical engineering department of the Lhokseumawe State Polytechnic. The research method used is descriptive qualitative, where the researcher will explore production data on the object of research and then compile the data into a production cost budget based on previous research studies and based on existing literature. This research is interesting because the cooking oil installation in the laboratory is different from the general factory, this is because the installation assets are included in BMN so that they cannot be included separately in the calculation of the production cost budget if the installation is carried out economically. This research can provide an ideal production cost budget calculation model in a laboratory at a state university or polytechnic.Keywords: Design, Budget, Cost, Production, Laboratory

One of the components of the environment that determines the success of plant cultivation is climate. To predict rainfall, the author uses the ARIMA Box Jenkins method, which is a quantitative forecasting method. The data used are data for the period July 2012 to June 2017. In this study, the right model is the ARIMA model (2,0,2) with Xt = 4.05668 + 0.9416Xt-1 - 1.0039Xt-2 - 0, 8558et-1 + 0.9617et-2 + et which is used to forecast rainfall for the next 12 periods. The selection is based on the smallest MSE (average error squared) value of 0.033401954 and the smallest RMSE (root mean square error value), which is 0.001115691 and the smallest MAPE (absolute average error percentage) is -0 , 00801773.
