It is the study of how we deal with scarcity, or how we use our limited resources. These resources are those things that can be used to produce goods and services. (p. 10) An economizing organization calls for an excellent management style to optimize profit and productivity for an organization to survive – either for profit or non – profit. Wherein productivity – the key to business profitability – is the result of how we can manage the processes for producing goods and services and is driven by implementing innovations (Watson, 1994, p. 17).Maximizing competitive advantage and minimizing competitive disadvantages methodology is one of the keys to attain productivity and profitability of an organization by increasing net profits, reducing expense costs, increasing process efficiency and effectiveness, maximized utilization of resources and the likes.
This process involves internal and external environment scanning which calls for evaluation. This evaluation will utilize statistical analysis to enumerate the strengths, weaknesses, opportunities, and threats (SWOT) present in the organization and out of the results, draw a solution.This entire process is called strategic management (Wheelen and Hunger, 2002, pp.
80-85). Fitzsimmons and Fitzsimmons (1998) found out that the integration of information technology helps to define the competitive strategy of successful firms. Furthermore, they added that Information Technology supports an organization’s competitive advantage. (p. 74) Heskett (1986), viewed investment on communications networks, databases and information technologies intensify strategic advantage.
Furthermore, He observed that the database a service firm possesses can be a hidden asset of strategic importance.The value of information is of importance to a strategizing organization that is why (Capron, 2001) he introduced as new component of economics. (p. 3). Similarly, Oak (2008) emphasized that computers have changed the way we work, be it any profession.
Computers play a vital role in every field. System integrations enable organization to perform processes in peak rate. (Watson, 2002) The conceptualization of the study entitled “The Development of a Computer-Based Laboratory Management System for Chemistry Laboratories of the University of the Assumption” emanated with the management theories cited.

Company Profile The University of the Assumption (U. A. ) is a private Archdiocesan Catholic university located at Unisite Subdivision, Del Pilar, City of San Fernando, Pampanga, Philippines.It was founded on January 12, 1963 and is the first and only Catholic Archdiocesan University in the Philippines and in Asia.
It is a non-profit and non-stock educational institution. Its current president is Bishop Roberto C. Mallari, D.
D, also the Auxiliary Bishop of the Archdiocese of Pampanga. The School of Technological Studies where the proponent is assigned is a cluster under the office of the Vice President for Academic Affairs. It is consist of three (3) departments namely; Architecture and Interior Design, Engineering and Computer Studies.
1. . Objectives of the Practicum As an academician, the practicumer would like to accomplish the following before the end of the practicum: 1.
Contribute to the school administration in bridging the gap between the theoretical and laboratory requirements of each engineering programs of the cluster, following the paradigms set by CHED and PAASCU by means of integrating computerized processes. 2. Conduct evaluation to existing laboratory processes and procedures to spot areas that need improvements in terms of efficiency, effectiveness and reliability. 3.Conduct research that will contribute to the improvement of the “existing” laboratory processes based on the results of accumulated data during the evaluation process. 4. Translate problem solutions found on the research conducted, into a computer based system that will answer the issues of efficiency, effectiveness and reliability.
1. 3. Significance of the Project The value of a study, a research or an invention can be measured by its significance, the degree how it alleviates the operations and processes of the existing system, and the acceptance and capability to respond to and satisfy the needs of the users – also called beneficiaries.According to Bishop Jeremiah the Hermit, “The most valuable thing on earth is time, because everything is acquired in time and all of man’s business is dictated by time. You could have food, clothing, fabulous homes, wisdom, and have all you want, but if you do not have time, it means – you have nothing. ” He also added that the worst thing on earth for man is the loss of time. Because by wasting time, we cannot acquire anything; we cannot have anything; by losing time, we lose everything.
We even lose ourselves. (”The Value of Time,” n. d. An educational institution caters an intangible product called service. But what makes an organization different from its contemporaries is how expedient, accurate and satisfactorily it conducts its processes. This can be intrinsic and extrinsic in nature, meaning how the organization deals with itself and how the organization deals with the customers or stakeholders. Although an educational institution environment differs from the industrial setting and from a business setting, a common denominator can be drawn from them – increasing profit and decreasing cost.
Minimizing astage of resources such as papers and human efforts due to inefficient systems is one of the ways of decreasing costs. The ability to expediently process customer transactions and even interdepartmental transactions increases profit. Proper allocation of resources such as buildings and rooms can both address the issue of profit and costs.
Failure to accomplish any of these areas will result to a company’s loss. Process is time – bound. Efficiency and Effectiveness is being dictated by time. Reliability, security, availability and access of data, and processes affect time.University laboratories try to mimic the industrial setting for the students to experience and to practice with. These are the places where most of the university’s assets and investments are housed. Students – also known as the clientele primarily accessed the laboratory services, tools, equipments and other facilities. Providing a strategic front end to the students may provide expedient response to request and issuance of equipments and supplies.
Monitoring, inventory, scheduling and management of laboratory supplies and process will be found on the backend of the system.However, anyone may argue that the process mentioned can be done using the paper – based or manual system. Strategically speaking modernized, competitive and service-oriented laboratories may find this method deficient and even expensive. Inconsistencies on records will poke another issue.
On the other hand Computer-based management systems will provide not only attractive infrastructure to customers but also efficient and economic resorts. Also maximization of the available resources thru proper scheduling will also be an advantage.Data stored on the database will be used for future decision making process, and will balance the “in” and “out” of resources. It is but a waste of resources if computers deployed on the university’s chemistry laboratories will just be used for simple encoding and internet surfing.
The proponent has a strong conviction that the uses of high end computer should be maximized and not merely for word processing and the likes. 1. 4 Definition of Terms PAASCU – Philippine Accrediting Association of Schools, Colleges and Universities CHAPTER 2 PRACTICUM PROGRAM 2. 1. Practicum ScheduleThe practicumer’s immersion commenced on January 8, 2009 and expected to end on June 8, 2009.
The practicumer’s daily schedule will start at 8:00 am until 5:30 pm in a “flexi-time” basis. Figure 2. 1. 1 and Figure 2. 1.
2 shows the Gantt chart of the practicum activities: Figure 2. 1. 1. Activities from January 2009 to May 2009 Figure 2. 1. 2. Activities from June 2009 to October 2009 2.
2. Type of Job Undergone One of the school’s prime objectives is to attain higher form of recognition to each academic performance and to adhere to standards set forth by accrediting organization.This endeavor entails a lot of evaluation and benchmarking to areas that need special attentions and improvements. Moreover, satisfaction of each student-clientele is also of great concern to private higher educational institutions (HEI’s). Thus, its financial sustainability and the ability to continually provide quality education services, depends on the patronage of its students.
The engineering department of the University of the Assumption is gearing towards PAASCU Accreditation. As a preparation, the department should be able to perform internal evaluation from its faculty line-up up to its facilities and services.The proponent was assigned to assist the department to examine papers and evaluate engineering laboratories. Laboratory evaluation results vary from one laboratory to another. The dean of the Technological Studies (which is also the practicum adviser of the proponent) found out that the Chemistry Laboratory which caters not only the engineering programs but also other departments has the most areas that need to be improved.
As the proponent framed the solutions to initial problems found, the Person in Charge of the Chemistry Laboratory and the industrial adviser both agree hat there is a need to computerize some processes within the Chemistry Laboratory. If not totally eradicate the problems, at least minimize them or expedite some processes. The proponent was asked to design database solutions with effective front and backend application for the laboratory and centralize process by introducing network infrastructure. 2. 3.
Problems Encountered, Lesson Learned and Solutions Transforming problem-solution into a software solution is not an easy task to do, and sometime is not always the real solution. It will incur costs when technology is being employed.Thus, improper analysis will lead to reverberating problem results. An interview with the Person in Charge of the Chemistry Laboratory was conducted (see Appendix B) to elicit problems that need to be analyzed. The following are the problems found arranged in order of complexity: 1. Inventory Processes – usually takes months to finish 2. No centralized and systematize database management system 3.
Record Keeping of Issuance and Request 4. No basic tracking of students entering the laboratory 5. No clear reservation process and procedure 6.
Manual laboratory scheduling processes CHAPTER 3PRACTICUM PROJECT 3. 1. Background of the Study It is but wise to comment that an organization operating without technology is lagging behind its competitors. Prevalence of IT and MIS department will prove the benefits computerization and telecommunications can bring to an organization. Expedience on transactions does not only satisfy and impress stakeholders but also cutting cost on the side of the organization. The proposed Network-Based Laboratory Management System for Chemistry Laboratory is a study that will amalgamate the three components of the computer system namely; Hardware, Software and Peopleware.The proponent strongly agrees that these three are inseparable.
The study would design front and backend application to be developed using Microsoft Visual Basic 6. 0. It is a network-based application that can be implemented either with wired or wireless infrastructure. Centralized storage and retrieval of information will be done using MySQL Database. Again, the study would frame front ends for student’s attendance monitoring within the laboratory using barcode reading technology and reservation of room and tools.An interface is also included for personnel dealing with requests and issuance of tools and supplies, and the reservation of laboratory room.
Thus, maintaining integrity and veracity of data. This study would produce an application that would serve more less two thousand students utilizing the chemistry laboratory each year. 3. 2. Statement of the Problem The study entitled The Development of a Network-Based Laboratory Management System for Chemistry Laboratories of the University of the Assumption, would like to answer the following questions: 1.How to identify the strength and weaknesses of the current chemistry laboratory management systems on the following area: a.
Laboratory utilization and scheduling b. Laboratory supplies, tools and equipment inventory and issuance processes c. Laboratory accession d. Laboratory Record Keeping 2.
Is there any significant difference as perceived by the respondents of the study between the current chemistry laboratory management system and the proposed Network-Based Laboratory Management System for Chemistry in terms of : e. Efficiency f. Effectiveness g.Reliability 3.
3. Objectives of the Project The project aims to develop a Network-Based Laboratory Management System for Chemistry Laboratories of the University of the Assumption Specifically the project aims to: 1. Identify the strengths and weaknesses of the current laboratory management system and to determine the areas that will need enhancement. 2. Evaluate the current system using the data gathered from the people involved with the laboratory utilization and management. 3. Draft guidelines and solution to address the problems found and elicited from data gathered. 4.
Create an integrated system for the following processes: request and issuance, inventory and control, laboratory scheduling and utilization, laboratory accession and record keeping. 3. 4. Scope and Limitations The study underpinned the underlying principles that could help analyze the problems of the current system. These lead to the blueprinting of the requirements for a development of a system that would answer these constraints.
Synthesizing all the former principles found on past researches and publications, the proponent had framed a solution. Moreover, these principles boxed the project, and determined the scope and limitation of it.The project focused on the development of LAN and computer based solution to the management of the engineering laboratories of the University of the Assumption. Thus, the application to be developed will be applicable and custom – tailored to the University’s laboratory set-up and requirements. This management solution is open – ended for future integration but currently limited to request and issuance, scheduling and utilization, accession and record keeping. It can’t be accessed from the internet. Implementation of total laboratory security is not covered by the project; a separate study should be conducted to realize this endeavor.Similarly, budgeting and financial endeavors of the laboratory is not covered by the project, but it can somehow assists in the decision-making process based on the inventory system posed by the proposed project.
Also, the inspection of the condition, content, composition and actual counts of each apparatus, tool and other related objects requested and returned is not covered by the study, therefore, it requires human predisposition to determined whether the former needs replacement, recalibration and other similar actions. The system would only track the maturity of each stock as entered by the encoder.However, the assurance whether older stocks were issued first or not is still in the control of the person in charge of the transaction. 3.
5. Problems Encountered, Lessons Learned and Solutions Migrating into a computerized system will entail a lot of process and other requirements. Problems encountered by the proponent in implementing the proposed system are: 1. Labeling supplies and tools with barcodes 2. Reconstruction of the laboratory to meet the requirement of the current system 3. Procurement of barcode readers, finger scanners, networking equipment 4.Networking processes to meet networking topology required The said problems hindered the expedience in evaluation and pilot testing of the new system. The proponent made a proposal to the management regarding the need to adopt the new system.
With the assistance of the industry advisers, needed materials for the realization of the said endeavor were properly channeled. 3. 6. Presentation of the Existing System The chemistry laboratories were located at the first floor of the Cruz Building. The storage, request and issuance is located at the middle of the laboratories as shown on figure 3. 6.
1 and figure 3. 6. 2 Figure 3. . 1 Left Side of the Storage, Request and Issuance Area Figure 3.
6. 2 Right Side of the Storage, Request and Issuance Area Students are entertained on the windows. Each transaction is recorded to logbooks (See Figure 3. 6. 3). Student assistants perform the preparation of request, answer queries and record transactions on logbooks. On the other hand students are asked to fill up forms depending on transactions being conducted.
These will be the basis for record keeping Figure 3. 6. 3 Transaction Processing on Chemistry Laboratory Students are asked to leave their ID’s when borrowing tools and equipment. Figure 3. 6. shows the system on borrowing.
Figure 3. 6. 4. Borrowing Process – ID System The office of the in charge of the laboratory is also located where tools and chemicals are housed. This is also the record section, where all present and past transactions are kept. Figure 3. 6. 5 and Figure 3.
6. 6 show the condition of the said office. Figure 3. 6. 5 The Record Keeping Office Figure 3. 6. 6 The Record Keeping Office Chemicals and other tools are labeled with masking tapes for identification. Tools are stored on cabinets with markings.
Figure 3. 6. 7 and Figure 3. 6.
8 depict the housekeeping and segregation of tools and supplies.Figure 3. 6. 7 Labeling of Chemicals Figure 3.
6. 8 Labeling of Tools Based on the interview (see appendix B) and initial investigation conducted by the proponent, it is notably found that the laboratory is having problems on the following areas: 1. No recordkeeping of supplies, only tools and equipment. 2. Inventory records are inconsistent 3. No logging in and out records of laboratory accessions by students 4. Presence of forms for request and issuance as basis of record validation and reference 5. All processes are being done manually – paper based and log book transactions 6.
No reservation policy. Mr. Gilbert Changcoco – the in charge of the chemistry laboratories asked the proponent in computerizing laboratory processes 3.
7. Presentation of Survey Results The perception of each respondent – Students, Faculty and Administrators is of greater importance, more than anything else in the framing of the study and of the application being developed by the proponent. Whether the proposed system was able to answer and satisfy the clamor of then clienteles to expedient transaction processing and reliable information is being relied on the feedbacks and evaluation of the respondents.
The researcher strongly believes that there is a need to integrate computerization on the chemistry laboratory processes. Appendix A shows questions being poked to the respondents. Same set of questionnaire is given to Students, Faculty Members and Administrators. Both systems – the current and the proposed were evaluated using the same instrument – Efficiency, Effectiveness and Reliability. With the aid of Engr. Diana B.
Pangilinan, MBA – the director of the Academic Research Office Department of the University of the Assumption, the survey results were processed using SPSS v17.Engr. Pangilinan also interpreted the result (See. Appendix E) 3. 7.
1 Respondents A. Students The proponent used the Slovin’s Sampling Formula in determining the number of respondents. A 7% margin of error was also used. Thus, n=N1+Ne2 Where, N = is the total population under investigation n = is the sample size to be surveyed e = is the margin of error (usually from 1% to 10%) Substituting the values will yield, n=2701+270(.
072) = 116. 2290 However rounding 116. 2290 will give 116, thus the proponent is confident with the sample size. Respondents are all engineering students.The 116 student respondents were picked randomly. Table 3.

Recommendation on the project Based on the result of the evaluated conducted by two groups of people.It is strongly suggested that the proposed system should be adopted by the Chemistry Laboratories of the University of the Assumption. During the evaluation periods, suggestions were given for future enhancement of the proposed system. One of these is to link the system to the university’s property custodian and to the finance department for the updates of records on procurement of supplies. Moreover, the system is also requested to be link to each student account for the collection of fees on breakages and damages made to some tools. The Laboratory Management System 1. (LMS 1. 0) Architecture LMS 1. 0 is Client-Server Architecture that utilize MySQL Database System as repository of data. Both the client and server applications are built using the Visual Basic 6. 0 programming language. Each component can be connected using either Wireless (802. 11) Network or Wired (Switched or Hubbed) Network. Figure 3. 8. 1 shows the Architecture of the proposed system, and Table 3. 8. 1 indicates the minimum and mandated requirement for the proposed system. Figure 3. 8. 1.

Figure 3. 8. 2 shows the ideal floor plan and office layout that can be adopted alongside the proposed System. The proponent also suggested some fixture arrangement and major rearrangement of the office layout. Areas enclosed with ovals are not present to the current floor plan of the chemistry lab. Issuance area for other laboratories is also noted to minimize intrusion of students on the laboratory, basically to secure tools and maintain orderliness within the premise. Figure 3. 8. 2.The Proposed Floor Plan and Office Layout Screen Shots This portion would like to give a brief eye view of the Laboratory Management System (LMS) 1. 0 Application for both Chemistry Request and Issuance Office and Student Access Application The Splash Screen The splash screen (Figure 3. 8. 3) shows the title of the application and the author of the software.

Computers offer a lot of advantage to an organization. It provides better and attractive frontier to clienteles. It expedites services and transaction processing. Undeniably, computer technologies nowadays enter the arena of business specifically service sector. Economists believe that information is powerful enough to manipulate the business world.Thus, a business without computer technology is living in chaos. Educational institutions use computers to serve their clienteles – the students. Records are the most important component of these institutions. Accuracy of information and the expedience in keeping and accessing them is one of utmost attention. Dissatisfaction of customers due to long waiting and inconsistent information is always been a problem. The advent of powerful computers with networking capabilities and large storage capacities solved these problems. However, a proper investment is a necessity. Maximization of computer uses is a much smarter action.The Chemistry Laboratories of the University of the Assumption is one of the best example of service-oriented, not only that an educational sector. Mentioned transactions are all eminent. Thus converting the manual processes into a computer technology based processes will attain cost cutting and better frontier to students. The proposed Network Based Laboratory Management System for Chemistry Laboratories of the University of the Assumption is a computer, network and database based application that will provide better front and back end interface to both laboratory users and managers.REFERENCES Capron, H.

We have, Nursing, HRM, Education, Psychology, Civil Engineering, Computer Engineering, Electronics Engineering, Industrial Engineering, and Interior Design. 2. What is the average student population do you server each year? Roughly, 21 class in a year, around 40 students each class. 3. How do you manage all of these? I have student assistants that help me during their free times. 4. Are there times that you do it all yourself? Yes. 5. Do you have computers inside the chemistry laboratory? If yes, where do use them?Yes, basically for filing and record keeping and some word processing. 6. What software do you use for filling and record keeping? I manually encode them to Excel and Word only. 7. Do you find this method efficient? No. It takes time to locate specific records. A lot of files need to be open first before I can find the information that I need. 8. What problems do you encounter with your filing and record keeping method? Entries for current request and issuance encoded by working students are not consistent for some time. Records on log books need to be re-encoded again to the computer.That makes work redundant. 9. Do you find centralization of filing using a database system would be beneficial? That was exactly, I wanted at the very start. It will help us a lot in the reporting process especially on the inventory. It will help us a lot in accessing student records expediently with utmost reliability. During semestral break, it is the peak where student records are of importance for clearing process. Log books method makes the work tedious. 10. How do you process requests, issuance, and clearing of tools, equipment and the likes? We issue forms such us request and breakage form.Requests and issuances are entered to log books for clearing purposes. 11. How do you keep these records? We keep them on cabinets for future references such as auditing and the likes. 12. How do you perform reporting out of these data? It is a very long task to do. You need to get them from the cabinets and start browsing each form and synthesize them to form a report. 13. Are there times that redundancy or inconsistency on records appear on the log book? Yes, especially when different student assistants served the same student. 14. How efficient your request, issuance, and clearing process?It is almost ok, except for the problem of searching specific record of student. It takes time to process that. 15. Do you record supply consumption? We record tools and equipment, but not supplies such as chemicals and powders. 16. How do you track your supplies? We just perform ocular inspection. We record consumption on log book. 17. Do you perform inventory? How long does it take to do inventory? Yes we do. It takes couples of weeks to do it. There are a lot of stocks to inspect. 18. Do you have system of basic monitoring of laboratory accession of student? None. The teacher does the attendance monitoring. 9. Do you think, computerization will solve problems you mentioned earlier? Yes. It will expedite processes. Records are consistent. Access of records is faster. Mr. Gilbert Z.
