This study was carried out to analyses the landcover change effects on soil erosion </em><em>to determine the extent and trend of changes in the study area; </em><em>estimate and characterize soil loss, and comparing the annual soil loss at different spatial scales. The </em><em>extent and trend of changes in the landcover </em><em>were estimated using Landsat Satellite Imageries for the year 2002 and 2017. RUSLE model was used to estimate soil loss and was characterized based on the expert description for tolerable soil loss concept. The results revealed the built-up area showed a consistent increase over time, from 349.5km<sup>2</sup> in 2002 to 592km<sup>2</sup> in 2017 of the total area. The vegetation covered about 933.4km<sup>2</sup> in 2002 but decreased to 509km<sup>2 </sup>in 2017. Similarly, the area covered by bare ground increased from 243.7km2 in 2002 to 620.4 km2 in 2017 but the waterbody increased from 0.29km<sup>2</sup> in 2002 to 0.72km<sup>2</sup> in 2017.&nbsp; The areas covered by </em><em>ag</em><em>riculture</em><em> also decreased from </em><em>1088.5km<sup>2</sup> in 2002 to 894km<sup>2</sup> in 2017. The </em><em>estimated soil loss</em><em> values </em><em>ranged from</em><em> 0 – 420,276 t ha-<sup>1</sup> yr-<sup>1</sup></em><em> with the mean of 231 and standard deviation 2272 in </em></p> <p><em>&nbsp;2002 while the soil loss </em><em>estimated in 2017 ranged from </em><em>0 – 186,920</em><em> t ha/ yr.</em><em> with the mean of 220 and the standard deviation 1312.3. </em><em>Comparatively, low erosion is observed in a total area of 45.5% in 2002 and 44.4% in 2017 while extremely severe erosion is observed in a total area of 29.8% in 2002 and 34.3% in 2017 in the study area which matches the actual bareground and agricultural land which can be attributed to change in C and P factors. </em><em>The study recommended that </em><em>enlightenment and awareness of erosion control should include land use habit of the people in the agricultural practice and care of vegetation</em></p> 2020-10-02T00:00:00+08:00 Copyright (c) 2020 Lamidi R.B, Okonufua E, Fakeye A.M, Ayegba M.O https://ijerat.com/index.php/ijerat/article/view/475 Artificial Intelligence in Food Industry 2020-09-15T03:07:56+08:00 Matthew N.

The aim of this study is to assess the consumers’ satisfaction on water supply service in Bahir Dar city, Ethiopia. The representative households were selected by stratified followed by systematic sampling techniques. The data was collected from 351 representative households using questionnaires and semi-structured interviews. The collected data was coded, edited and entered into STATA (Statistical analysis software) version 14.2 for further statistical analysis. Chi-square test and order logistic regression were conducted. The chi-square test indicated that relatively </em><em>males were more satisfied than females. Customers with the educational status of having secondary and above educational level were relatively unsatisfied</em><em>. Similarly, customers who had their own houses were more satisfied than customers who got house from the rent of individuals and agencies, while customers having low and middle income were significantly more satisfied than customers having high-income levels. Results from the order logistic regression indicated that total customer satisfaction had a significant relation with continuity of water supply, water pressure and scheduling of water service. The result also indicated that most customers were not willing to pay additional payment for the existing satisfaction level but customers were willing to pay more if there was a significant improvement in its overall customer services, particularly on the three least rated satisfaction drivers continuous water supply, water pressure and scheduling of water service. </em></p> <p>&nbsp;</p> 2020-10-08T00:00:00+08:00 Copyright (c) 2020 Misganaw Mintesnot Tessema https://ijerat.com/index.php/ijerat/article/view/485 Reverse Engineering Approach for the Design of Gear-box for a Hand-guided Vibratory Roller Soil-Compactor 2020-10-08T22:55:56+08:00 S.

Fabiyi osagie.ibhadode@gmail.com Adebayo Adekunle osagie.ibhadode@gmail.com <p><em>Soil compaction is one of the most critical components in the construction of roads, airfields, embankments and foundations. For a developing country like Nigeria, the equipment needed to compact soil for the above-mentioned purposes especially in the rural areas needs to be readily available. However, this is usually not the case as most of the available equipment like Roller compactors are imported. A cheaper and faster way to make them available is by reproducing the existing ones through ‘Reverse Engineering’. Reverse Engineering (RE) can be defined as the process of discovering the technological principles of a device, object or system through analysis of its structure, function and operation usually for the purpose of reproducing it or for a more competitive procurement. In this project, the Reverse Engineering design (mechanical) of a parallel shaft gearbox for use in a hand roller compactor was carried-out. Its entire functionality was outlined and the engine capacity to be coupled to the gear box in order to provide the required energy for an acceptable soil compaction was determined. The energy required according to Standard Compaction Test AS 1289 – E1.1 ranges from 595 KJ/m<sup>3</sup> to 2072 KJ/m<sup>3</sup> according to the Modified Compaction Test AS 1289 – E2.1. Therefore, the energy required for various levels of compaction, ranges between these two values. Four different soil types were considered and the energy required for different ‘Compacted lift thicknesses’ using the parameters of the hand roller compactor were found to fall within the above values (595 – 2072 KJ/m<sup>3</sup>), thus, justifying the viability of this design procedure.</em></p> 2020-10-08T00:00:00+08:00 Copyright (c) 2020 S.

This study explores the vehicle engine assembly line for Station 2 Cylinder Block Products, which has a cycle time of 184 seconds, while the company targets a 180 second for takt time. Though ideally, the cycle time should not exceed the takt time. This research aims to identify the Non-Value Added (NVA) activities in Station 2 and minimize them with Karakuri Kaizen. The results of the Process Activity Mapping (PAM) show that Station 2 Cylinder Block has 16 Value Added (VA) activities, 19 Necessary Non-Value Added (NNVA) activities, and 7 Non-Value Added (NVA) activities with a manufacturing cycle effectiveness (MCE) 78%. Based on the activity mapping, the researchers find the primary causes and designed a proposed improvement using the Karakuri Kaizen method to reduce two NVA activities. The company can speed up the cycle time at Station 2 Cylinder Block to 180 seconds and the MCE to 80% by implementing Karakuri Kaizen.</em></p> 2020-10-14T00:00:00+08:00 Copyright (c) 2020 Alur Pogowonto, Uly Amrina https://ijerat.com/index.php/ijerat/article/view/486 A Simple and Fast Method to Design Robotic Hands 2020-10-09T00:54:08+08:00 Atefeh Hasan-Zadeh hasanzadeh.a@ut.ac.ir Osameh Irandoust osameh.irandoust@ut.ac.ir Maryam Fayaz mfr98.fayaz@gmail.com Asiyeh Sedghi asiyehsedghi24@gmail.com Alireza Fateminiya alirezafateminiya@gmail.com Aref Gheragali aref.cheraghali@ut.ac.ir Mahdiyeh Rahban shakila.rahban@gmail.com Arman Karami Armankaramihalashi47474748@gmail.com Mohammadreza Nazemzadeh Mohammadrezanazemzadeh7@gmail.com Mehrangiz Rostami mehr.angiz.ravar@ut.ac.ir Mehdi Raeisosadat mehdireis@ut.ac.ir <p>This paper has investigated the mathematical approaches used in the design of robots in order to identify the best method to design robotic hands. For this purpose and following the main origin of the subject, the results obtained from the biomechanics of the legs of different families of insects have been collected. Geometric measurements of various pairs of legs designed for walking, running, swimming, digging and other related tasks have been presented from an entomological point of view and their relationship to the Fibonacci sequence. With the application of the optimization methods, the results obtained from observing the relationships between the design of organs (legs) of different families of insects with multi-joint structures and different mechanical abilities of the legs have been presented. These studies could be a natural inspiration for the development of multifunctional robotic arm technology. In the following, studies on the mechanical design of 4 configurations of robotic compliant fingers based on a compliant mechanism have been examined and analyzed to reduce costs and control complexity. Geometric parameters of compliant finger design as well as model prediction are performed by the Fibonacci sequence, which in addition to providing natural behavior, will be faster and easier than optimization methods. The design provided from the cited sources will be a suitable response to meet the needs of commercial prostheses and robotic arms.</p> 2020-10-21T00:00:00+08:00 Copyright (c) 2020 Atefeh Hasan-Zadeh, Osameh Irandoust, Maryam Fayaz, Asiyeh Sedghi, Alireza Fateminiya, Aref Gheragali, Mahdiyeh Rahban, Arman Karami, Mohammadreza Nazemzadeh, Mehrangiz Rostami, Mehdi Raeisosadat https://ijerat.com/index.php/ijerat/article/view/491 Analysis of Quality Control for Automatic Transmission Products MCVT Model By Six Sigma Approach at PT HPPM, Indonesia 2020-10-21T12:28:46+08:00 Betrhriza Hanum bethriza@mercubuana.ac.id Ragil Pardiyono ragilpardiyono@gmail.com Andy Kurniawan bethriza@mercubuana.ac.id <p>PT HPPM is a manufacturing company engaged in the automotive sector. The products produced include Automatic Transmission (ATM), Engine Valve (EV), Four Wheel Drive (4WD), and Stell Belt, which are marketed at home and abroad. In carrying out its production activities, PT HPPM has guidelines for controlling its products' quality to compete in the automotive industry, including ATM products with the MCVT (Medium Continuously Variable Transmission) model. The method used in the quality control analysis of this research is Six Sigma, a vision of quality improvement towards a target of 3,4 failures per million opportunities for every transaction of goods and services, Gasperz (2005). To apply the Six Sigma concept, a measurement method is needed to assist the implementation of Six Sigma in the company. There are five steps in this method's stages, namely DMAIC (Define, Measure, Analyze, Improve, Control).</p> <p>There are four potential Critical To Quality (CTQ) that cause the product to become defective or fail in the MCVT model, namely NG Leak, NG Gata, NG Circlip, and NG OPC. The highest defect is NG Leak defect, 127 units with a percentage of 45.68% of the total number of defects produced—then followed by defects NG Gata with 79 units with a percentage of 28.42%. Meanwhile, another defect is NG Circlip, with 62 units with a percentage of 22.30%, then NG OPC as many as ten units with a percentage of 3.60%.</p> <p> By using the Six Sigma method and the DMAIC step (Define, Measure, Analyze, Improve, Control), it can be seen that the quality of MCVT products in the Main Line 1 process is good, which is at the level of 4,876 sigma with 370 Defect Per Million Opportunity (DPMO). From the Define stage by mapping and identifying problems to find out the causes of defective products, the Measure Stage by calculating the stability of the poses using the SPC method to determine the Proportion, CL, UCL, and LCL and calculating the process capability to determine the sigma level value and the DPMO value. The Analyze stage identifies the source of the problem with the Fishbone Diagram, the Improve stage looks for solutions using the 5W1H method, then Control to maintain and maintain process improvements. The results showed a decrease in the DPMO value from 383 units to 370 and an increase in the sigma level value from 4,868 to 4,876. This shows that the company has been able to implement a good quality control system</p> <p> </p> <p> </p> 2020-10-29T00:00:00+08:00 Copyright (c) 2020 Betrhriza Hanum Hanum, Ragil Pardiyono Pardiyono, Andy Kurniawan https://ijerat.com/index.php/ijerat/article/view/490 Comparative Analysis of Raw Materials Control Using JIT and EOQ method For Cost Efficiency of Raw Material Supply in Automotive Components Company Bekasi, Indonesia 2020-10-21T12:22:58+08:00 Jakfat haekal jakfat.haekal@mercubuana.ac.id Ifnu Setiawan ifnusetiawan15@gmail.com <p>The company where the author conducted research is a company engaged in the automotive sector that produces various seals for motor vehicles and heavy equipment.
