Abstract

Astra Manufacturing Polytechnic is educational institution under the auspices of PT Astra International (Astra Group) which has total of approximately 700 students. Industrial culture is adopted by applying discipline in the form of attendance. Students who do not arrive on time will be charged Minus Hours. Students do attendance with attendance cards and recapitulated by each study program admin and takes 700 minutes (all study programs) every week to produce minus hours as calculation of student errors. Many students are cheating in the attendance process. Because attendance cards can be deposited to other students. To overcome this, the attendance method was replaced by initially using machine and attendance card with finger scanner and integrated finger scanner integrase application with sql server database. So hopefully cheating and recapitulation time can be eliminated. In the implementation of this research extreme programming is used as software development methodology. After implementation of the application is able to eliminate 700 minutes and eliminate the use of attendance cards.

Abstract

Manual material handling (MMH) is one of the most vulnerable forms of activity with the emergence of risk of injury to the body, for example musculoskeletal disorders (MSDs). This study aims to analyze the work posture carried out by workers at PT. Multitech Advanced Printing Indonesia on the work of moving raw materials. The work includes a series of activities, namely lifting, carrying, and lowering. Of the three activities, lowering was chosen as the most potentially dangerous for workers. This study uses the Quick Exposure Check (QEC) method and Manual Task Risk Assessment (ManTRA) to assess the risk of work injury. Based on the results of the QEC method, the value obtained is 59.88% while the ManTRA method gives the highest value of 2 points from the three conditions for the improvement work posture. Both methods assess work posture as dangerous becauses of the bending position of the back

Abstract

External corrosion on mature oil and gas field installation very challenging issues. External corrosion of pipeline riser on tidal zone is the most case for pipeline corrosion [2]. API 5L X52 is familiar pipeline for offshore oil and gas production facilities. Pipeline riser external corrosion on tidal zone have some consequences, time constrain related tidal cycle, production loss, oil spill impact to company reputation, costly maintenance. This research intended to find out effect of tidal cycle and salt water salinity to the rate and type of corrosion on API 5l X52 pipeline riser. Tidal cycle is modeling by wet and dry coupon on salt water. Corrosion rate measure by weight loss coupon. Corrosion product examine by XRD. Chloride contents and oxygen dissolve combination resulting maximum corrosion rate. Oxygen dissolve is main factor to corrosion on salt water. Maximum oxygen dissolve on salt water concentration 3.5% wt. On high salinity salt water corrosion rate depend oxygen dissolve [2]. Tidal cycle has impact to corrosion rate. General corrosion type happen on all coupon with corrosion product component Fe2O3, Fe3O4 examined by XRD.

Abstract

Product quality is an important factor that underlies the consumer's decision to choose the desired product and service. Quality can initially be determined by the company, but in subsequent developments, quality planning must pay attention to the wants and needs of consumers. In providing excellent service to customers, the company needs to apply the concept of lean thinking, intending to reduce waste. A methodology is needed that can reduce product variations and production process errors with the Six Sigma methodology. The second application is often called Lean Six Sigma. This paper aims to improve the quality of fluid carrier tank products. The number of defective products, mainly on welding, cutting and bending process, so rework is needed that causes companies to suffer losses. The company expects to reduce product defects by less than 5%. The welding, cutting and bending process are the highest contributor to defective products, so that process improvement is limited to these processes. The process of welding, cutting and bending process is considered a major problem, so the main concern for quality improvement is for the main problem. Sigma, the initial welding, cutting and bending process in a sequence is quite good. The target to be achieved is to increase the sigma value of both processes. The alternative is chosen, namely creating and supervising SOPs, and training to improve the skills, knowledge, and abilities of each employee. These alternatives can increase the sigma value from the initial conditions from 2.93 to 3.20. The increase in sigma value indicates a decrease in the level of defects per million opportunities (DPMO).

Abstract

Aluminum alloy is non-Ferro material that very difficult to amalgamate using fusion welding, so it requires friction method. Friction welding is process for connecting metals without melting (solid state process), Process merging between the rotating speeds of material forces cause heat friction and at somepoint can be able to melt the materials and melting process occurs. The study aim is to determine tensile strength results from friction weld joints due to changes in ambient temperature of room. Material test is Aluminum A6061. Friction welding uses a lathe with rotation speed of 1600 rpm. The length size of material is 80 mm and 120 mm, diameter 15 mm, Champer angle 15°, 65 bar friction force for 60 seconds, final compressive force 375 bar for 60 seconds and variations in ambient temperature namely room temperature (T0),125 °C,150°C. The A 6061 joint produces the highest tensile strength at temperature 150 oC (188 MPa).

Abstract

Laundry is business engaged in services that are now commonly found. The high demand for laundry services makes laundry owners in Sungai Bambu, North Jakarta look for ways to keep transaction records neatly organized and not lose records or damage that is often experienced by customers or owners. In addition, employees must calculate the total price of the weight of the items to be washed, so that it takes a long time. Laundry also provides a variety of laundry services that can be added at any time. Besides making manual reports. To overcome this, laundry service information system is designed using the waterfall method built with Visual Studio as an interface and SQL Server as data storage. Design of this information system will make it easy to collect transaction data and minimize data loss or damage, generate automatic reports, and can perform special laundry services.

Abstract

The burn marks on the Pias Card are located on a scale of 6 -18 data is the sunshine duration. Determination of Region of Interest (RoI) is done with the aim of reducing noise in the Pias Card image segmentation process. solar irradiation system developed to determine areas that are considered important according to scale using the Cropping method. The system testing was carried out using 107 data of Pias Cards. Type Pias Card is SO-40F. Cropping principle is still manual, namely by setting the height of the image (Heigth), the left border (Left), and the right border (Right) in pixels. Based on testing, the best value settings are Heigth (H) = 5, Left (L) = 125, and Right (R) = 250 with a percentage of cropping success is 91.67%.

Abstract

The conducted research studied a feature extraction method in a musical instrument tone recognition system. The purpose of this study was to obtain a number of feature extraction coefficients that are smaller than those obtained in previous studies. The studied feature extraction was a DCT (Discrete Cosine Transform)-based segment averaging and Gaussian windowing. The testing of the musical instrument's tone recognition system was carried out using pianica, tenor recorder, and bellyra musical instruments, each of which represented many, several, and one significant local peaks in the transform domain. The test results showed that the optimal number of feature extraction coefficient was 8 coefficients, which could give a recognition rate of up to 100%. The test results were achieved using a Gaussian window with a sigma value of 2-6, and a 128 points DCT.
