Abstract

The electric motor is a device that serves to transform electrical energy into mechanical energy of motion. In this case the designed control system motor 3 phase by Smartphones through bluetooth network to find out the effective range of extremity. The methods used in the form of data capture of measurement effective range the furthest that can be reached by bluetooth to activate relay SPDT and motor 3 phase. Results of testing the most effective distance of the otomasisasi control system of motor 3 phase maximum as far as 15 meters with a time of pause 0.5 seconds.

Abstract

Making heart rate module aims to obtain information module accuracy compared to standard gauge (Pulse Oxymetri). Work system which used using finger and sensor-based Arduino Uno which results are displayed on the LCD. This research uses the method by means of comparing the results of calculating heart rate on the module with the standard gauge (pulse oxymetri) conducted in 5 respondents, each of the respondents was conducted 5 times of measurement. The measurement is done by way of a coexisting between module and checklists (pulse oxymetri) on the index finger of the right and left using the finger sensor. The results of this study showed this tool be eligible to use the benchmarking measurement using Pulse with Oxymetri as much as 5 times by 5 respondents with an average error of results of 0.38%.

Abstract

The rapid rate of growth of technology and information in the modern era today, encourages companies to further develop their thoughts and views to maximize the goals and objectives set. The Place to Practice Business Skills (TPKU), is a business engaged in the field of convection managed by Tebuireng Boarding School. One of the most widely used convection products is the school uniform. In producing school uniforms, convection also strives to continuously improve quality by pressing the number of defects in the product. Some things that need to be done are identifying the factors that cause disability using the Six Sigma method, calculate the quality of sigma, and propose appropriate actions to control the quality of school uniforms. Six sigma is a tool of quality improvement toward the 3,4 target of failure per a million opportunities for each production. So six sigma is one of the new methods in the field of quality management aimed at quality control and improvement. By using the six sigma method, it can be seen that there are seven types of defects (CTQ) that occur in school uniform products. The two most common types of defects are: seams that are not tidy with a percentage of 51.1% and stain on uniform of 28.4%. For the quality of school uniforms produced by Tebuireng Convection is still low ie 2.95 sigma with a product defect rate as much 74830 products in one million products (DPMO). From the application of these six sigma, it can be concluded that the proposed action to be done convection to reduce the level of product defects is to focus its supervision on improving employee performance, engine performance, applicable work standards, existing facilities and infrastructure, provide motivation to work, and improve time management well.

Abstract

The controlling planning of raw material needs in a company is very important to keep productivity on production activityand its influence on the material procurement cost. UD. Jaya Abadi Solution is one of the company that produces various fodder from the waste of animal feed manufacturing factory. The fluctuation often happens in raw material availability for production process especially “tumpi” raw materialwhich causes the production process is not optimal. The purpose of the research is to control “tumpi” raw material availability by using Economic Order Quantity (EOQ) method and Period Order Quantity (POQ) methodand to know the different cost between the company calculation and EOQ and POQ methods caculations. The methods used in this research are Economic Order Quantity (EOQ) method and Period Order Quantity (POQ) method, these methods are expected to be able to cope the fluctuation of the “tumpi” raw material availability. Based on the result of the research using Economic Order Quantity (EOQ) method and Period Order Quantity (POQ) method yielded is EOQ value of 220 tons with total cost of Rp. 113.165.509, while POQ value is 205 tons with the total cost of Rp. 113.285.546. The different cost produced is 19 % compared to the company total cost.

Abstract

The aims of this activity is the application of furnace and pottery design training to help improve the quality and quantity pottery products. The methods of implementing this activity is the implementation team analyzes the problems of the partner team (Mr. Suhartoko). The results of the analysis revealed that Mr. Suhartoko’s pottery business still used wood-burning stoves, ability to design pottery motifs (grading techniques) that are underdeveloped and marketing management that has not been managed optimally. Based on the results of discussions and request of partner teams. Then the design is carried out for the manufacture of controlled system furnaces. Training preparation to design pottery motifs (grading techniques) and marketing workshops. At the end of the activity the community partnership program was facilitated and evaluated. The results of the community partnership program activities are an increase in the quality of pottery products after using a controlled furnace system. While still using the manual furnace, the pottery produced is only made of clay after using a controlled furnace system. The pottery produced is capable of producing pottery made of ceramics. In quantity, there was an increase in the production of pottery, which were from 8-10 pottery each time it processed to 22-24 pottery. While, in terms of design, pottery motifs have started to develop and are able to selling high. The indicator is that the selling price of pottery products increases from 10 thousand rupiahs to 15 thousand rupiahs for each pottery product to 100 thousand rupiahs to 150 thousand rupiahs for each pottery product. At this time, Pottery product marketing has also begun to penetrate the gallery, hotel and café.

Abstract

The need for learning media in the Machine Element II course makes the transmission trainer to be immediately presented in order to become a means of supporting student learning. In a transmission trainer system a driving mechanism is needed so that the transmission can rotate. The drive mechanism must be reliable to ensure the transmission can rotate without constraints. Therefore, it is necessary to design and calculate in designing the transmission driving mechanism. The purpose of this study was to determine the design and calculation of the transmission trainer drive system. The design results show that the required motor specs are motors with 250 watts of power, driven pulley diameter 50 mm, driven pulley diameter 250 mm, distance between pulley axes is 335 mm. use v-belt type A with a length of 1175 mm. this drive system mechanism will produce a final torque of 393.01 kg.mm which is considered good because it is higher than the planned torque that is 325,85 kg.mm.
