Development of a Four Speed Manual Transmission System Instructional Model

Authors: Vergel E. Tampes , Darrel Lee E. Tampes and Keno S. Domingo

Abstract: Improvement of the project design in every institution is a never-ending process in order to cope with the needs. In college and universities, said that having an instructional model is helpful for understanding a lesson. To contribute to the process, a four-speed manual transmission system instructional model was made. The design of improved project is more suitable for hands-on experiences and it also provides a different kind of activities to gain more knowledge about manual transmission system. The study is about manual transmission, specifically, Toyota four speed manual transmission was used. It is a speed power changing device located between the engine and the driving wheels of a vehicle. The development of the project would be helpful in preparation of students for their TESDA assessment. The design project was rehabilitated and restored in the author’s residence from November 2016 to May 2017. The study was focused in manual transmission only, this is limited the discussion of other parts and assembly of the project.

Analysis on the Occupational Risk Factors of Manual Tasks in Wood Furniture Manufacturing Associated to Musculoskeletal Disorders of the Hand and Wrists

Authors: Justine Karl D. Ambat, Anthea Marie C. Pido, and Gerry M. Castillo

Abstract: The study was conducted to identify the ergonomic risk factors of manual tasks in wood furniture manufacturing associated to musculoskeletal disorders of woodcarvers. Job related attributes such as working condition, types of activities perform and working postures were tested with the frequency and severity of the symptoms to identify the risk factors that contribute to the occurrence of musculoskeletal disorders and other related illness to woodcarving. The participants of the study were one hundred (100) woodcarvers residing at Pakil, Paete, Laguna. Woodcarving process was considered in the study, which involved shaping of wood, lifting, design detailing, wood finishing and even final touches like painting and varnishing. Through industrial engineering tools and techniques, ergonomic risk factors in woodcarving were then identified. Job related attributes and frequency and severity of musculoskeletal disorders symptoms were also obtained. Job Strain Index worksheet was used to evaluate working condition and determine variables that affects musculoskeletal disorder occurrence like intensity of exertion, duration of exertion, efferts per minute, Hand/wrist posture, speed of work, and durations per day. These variables determined the rating value to evaluate if a worker is within safe work or not.

Analysis on the Machine Performance of CNC Machine using Overall Equipment Effectiveness at Alpha Techno Precision Toolings, Inc.

Authors: Lhoreby Ann A. Rosos, Eric A. Tablizo, and Gerry M. Castillo

Abstract: This study measures the machine performance of the CNC machine using Overall Equipment Effectiveness (OEE) at Alpha Techno Precision Toolings, Inc. Using daily monitoring sheets given to the CNC operators and OEE sheet, it is identified that machine performance of CNC section was poor and failed on the world class OEE standard. The overall results of availability, performance and quality shows that availability (68.27%) has the lowest percentage causing a poor machine performance on the CNC section. From the OEE factors that cause poor results on overall machine performance, downtime losses (31.73%) shows the highest factor. Possible recommendations were given in order to improve the machine performance on Alpha Techno Precision Toolings, Inc.

Factors Affecting Labor Productivity in the Salt Producers of Cavite

Authors: Julius Austin P. Olores, Jerome G. Pangilinan, and Gerry M. Castillo

Abstract: The study identified the significant factors affecting labor productivity in the salt producers of Cavite. The significant factors consisted of manpower, management, materials and equipment, methods and other related factors that affect the labor productivity of the salt farmers in the production of salt. The subjects in the study were composed of 54 respondents coming from the different salt producers of Cavite. Four salt farms were considered in the study namely Bagnas, De Guzman, Encarnacion and Villamar Salt Farms, which are all located in Kawit and Noveleta, Cavite. Descriptive analysis was made to determine the demographic profile of the respondents such as age, gender and years in service. Descriptive analysis was also made to determine the labor productivity of the salt farmers. The result of correlation analysis showed that the significant factors that affect labor productivity are: manpower, management, materials and equipment, methods and other related factors. Based on the result of the study, given thirty (30) factors and six (6) labor productivity questions, there are twenty (20) results factors that have significant effect on labor productivity. Furthermore the result of the study has found that there have been labor productivity problems in the salt producers in Cavite, and disclosed the four general significant factors, which were rated to have more than a moderate influence on productivity such as manpower, management, materials and equipment and methods. Most of these factors have high correlation to materials and equipment, methods and management such as old and inefficiency of equipment, shortage of tools and equipment, long working hours under the sun, lack of protective gears and lack of available workers.

Design and Development of an Improved Protective Mask for Welders

Authors: Ross Anthony M. Odvina, Leinard Jay E. Ramirez, and Gerry M. Castillo

Abstract: The study was primarily conducted to design and improve the existing protective mask used by welders in the welding shop through the application of ergonomics using 5th and 95th percentile and anthropometry. It also aimed to determine the attributes of the existing protective masks, identify the problems or discomforts that were experienced by the welders, ergonomic activities that will correct the problem, determine the cost that will be used to develop and improve the existing mask and compare the anthropometric dimensions of the existing protective mask with the proposed protective mask designs to show the deficiency of the existing design. The study had required data such as the attributes of the existing protective mask, the problems and discomforts experienced, and the anthropometric dimensions of the welders. It was conducted in the form of survey questionnaire and interview from welding shops of selected areas in Cavite, while the dimensions of the protective mask were obtained through measuring the length, width, depth, and weight of the mask. The results of the study showed that the problems and discomforts experienced by the welders were inhaling fumes, eye irritation, and having a hard time seeing the front view. A prototype protective mask was developed considering relevant facial and head anthropometry gathered from the welders. The proposed protective mask used automatic darkening lens, adjustable headgear, polyamide plastic for the face cover, and respirator to filter the fumes caused by the welding process. The prototype was evaluated using five indicators (Functionality, Aesthetics, Durability, Safety, and Workability). Results showed that respondents were significantly satisfied with the prototype in all features evaluated. It was more expensive compared to the existing mask because of the materials used to develop and improved the protective mask. However, it has automatic lens and can be charge by solar power, light face cover, easy adjustable headgear, and respirator so that the user will not inhale any fumes cause by the welding process.

Assessment on the Conformance of Facilities Based on the Needs of Persons with Disabilities at Cavite State University System

Authors: Christian Eric A. Novicio, Joseph M. Legaspi, and Gerry M. Castillo

Abstract: PWDs are accessing different facilities, and it must be accessible as it is stated in the law that “the State shall ensure the attainment of a barrier-free environment that will enable disabled persons to have access in public and private buildings and establishments and such other places” mentioned in Republic Act no. 344, also known as the “Accessibility Law”. The main purpose of this study was to assess if the facilities of the Cavite State University conforms to the needs of persons with disabilities that would access the facilities. The researchers used assessment and evaluation forms adapted from Accessibility Law of the Philippines. As a result, Silang campus got the highest compliance of accessibility. The evaluation of the recommended facility resulted positively to be a great help to PWDs.
