The Development of automatic melinjo puncher machine using pneumatics pressure
No full textMelinjo chip is one of Indonesia’s facourite food. Melinjo chip is not only marketed in Indonesia, but they have been exported to various countries including Netherlands, United State of America, and Middle East. Mostly melinjo chips are produced in the traditional way by home industry and MSMEs. The existing machines to produce melinjo chips are not operated fully automatically; hence they still require significant operator involvement. The machine developed in this study uses a pneumatics pressure as power driver. Pneumatics cylinders are used to push the melinjo seeds onto the flattening base, and to move the puncher rod during flattening process. The developed automatic melinjo punching machine has been tested. The tests were carried out to determine the parameters used for programming the machine, sucah as punching time and pneumatic presure, and for checking the capacity of the machine. The test results show that the most effective punching time is 5 seconds at pressure between 5-7 bar. In 5 seconds, the machine can change melinjo seed into chips shape with thickness in between 1,20-1,45 mm. The capacity of the machine in processing melinjo has also been tested. The results showed that this machine can process 528 melinjo into chips shape melinjo per hour

Improvement of autonomous railway monitoring robot prototype as fault detection on railway
Get PDFOne of the causes of accidents on trains to date has been caused by damage of railways such as cracked rails, broken rails and other rail defects. Currently, the inspection of the railway line is still carried out manually by the railway inspection officer or Petugas Penilik Jalan Rel (PPJ). However, there is a prototype Autonomous Railways Monitoring Robot (ARMR) which is a prototype inspection robot that can perform rail line checks automatically and be monitored remotely to detect any faults on the railway. The ARMR prototype detects faults as well as locations that are subsequently delivered to users by utilizing some Internet of Things (IoT) features. Faults detected by ARMR prototypes are faults as rail damage. But, the ARMR prototype is unable to distinguish a fault and rail connection. This final task aims to improve armr prototype capabilities to produce information in the form of depth and width of faults, and to distinguish faults and rail connections. The VL6180X sensor is a laser- based distance sensor used as a depth detector for rail faults and rail connections. The Incremental Encoder is enabled to measure the width of the rail fault. The result of ten experiments at 20 cm/s, the ARMR prototype was able to produce 78 mm fault depth size information with an error value of 1,67%, produce 5 mm wide fault width information with an error value of 2,48 % and be able to distinguish faults and connections with 72 % accuracy for the comparison of the distance between the ARMR prototype and the distance shown on google maps.One of the causes of accidents on trains to date has been caused by damage of railways such as cracked rails, broken rails and other rail defects.

A prototype of Autonomous Railways Monitoring Robot (ARMR) is a prototype of inspection robot that can perform rail line checks automatically and be monitored remotely to detect any faults on the railway. The robot detects the width of the rail fault by reading the number of pulse train sent by the encoder and the depth of the rail fault by reading the time delay signal received by the distance sensor. The result of rail fault and location are subsequently delivered to users by utilizing several features of the Internet of Things (IoT). Faults detected by ARMR prototype, but it is unable to distinguish a fault and rail connection. To overcome this weakness, a camera is used that will capture the shape of the fault or rail connection. The results of the experiment at a speed of 20 cm / s, the robot is able to detect the width of the rail fault of 78 mm with an error value of 1.67%, and a fault width of 5 mm with an error value of 2.48%. The robot also able to distinguish faults and connections with 72 % accuracy for the comparison of the distance between the ARMR prototype and the distance shown on google maps
Performance measurement using balance scorecard leading to strategy formulation: A case study in water company
Get PDFOrganization goals could be achieved by translating vision and mission into strategy. The strategy should be carefully formulated to direct the operation plans to work in harmony to achieve the goal. This research aims to show how the strategy is formulated based on the performance measurement result. The performance indicators are generated using the Balanced Scorecard approach with its four perspectives; financial, customer, internal business process, and learning and growth. Once these indicators and their benchmarks are defined, performance measurement is carried out. The performance measurement result is then input into a Strength-Weakness-Opportunity-Threat (SWOT) matrix. This approach proved that it could help the company review its existing strategy achievements and competitive position. Furthermore, the SWOT analysis proposes some potential actions taken by the company, which fall on Offensive, Defensive, Adjust, and Survive strategies
