RESULT AND DISCUSSION

III. RESULT AND DISCUSSION

Inquiry learning development carried out by the steps of learning through explanation of learning objectives, dividing the inquiry or user manual lab work, assigning students to carry out the inquiry, to monitor the implementation of the inquiry and conclude the inquiry together. Explanation of learning objectives and divide inquiry or user manual practicum through debriefing activities and assistance with student assistants. Inquiry learning is done assigning students to carry out inquiry into sixteen titles lab and lab work done every four titles through seminars monitoring lab results so that students can reflect on the learning experience. Results seminar lab results can provide a conclusion shared learning outcomes that have been carried out in the laboratory.

During the learning takes place, students are given the opportunity to gain experience of learning to identify mismatches example by testing requirements, incompatibility test results and their propensity data outside the specifications. Results of learning reflection could be concluded that, (1) every step of the experiment followed by manual safety, (2) the equipment or instrumentation and materials given specification refers to quality assurance testing, (3) the work procedures can be developed using standard or nonstandard methods incorporating aspects of the verification or validation of the method, (4) learning modules can be equipped with a procedure to check and monitor the quality of solution, (5) analysis of the data furnished by the calculation of validation or verification methods and manual data presentation which refers to the quality control testing and ( 6) testing is done by using a test sample that is applicable and current.

2. Development of Assessment Tools The instrument performance learning to use performance criteria contained in the unit

of competency on three units of competence, (1) MSL973002A prepare a working solution, (2) MSL974001A prepare, standardize, and use the solution, and (3) MSL974003A testing and chemical procedures in accordance with this course with SKKNI field Services Laboratory testing Laboratory Translation of Australian Operations Training Package (MSL09). The validation of construct the instruments carried by the competence of assessors who have expertise in the development of assessment tools and has the technical competence in the field of chemical testing.

1. The results of validation of self-assessment showed that instrumentation developed ratings have compatibility with the substance requirements, construction and language. Assessment instruments that have been developed in accordance with the requirements of the substance of performance criteria in competence units referenced against the standard. Ratings also have to meet the construction requirements of the question, the principle of assessment, it is easy to understand, and have a clear and complete information. Instrumentation developed has met the language requirements, effective, efficient and communicative. According to the validator, the assessment instrument can be adapted to routine activities in the lab so that students can gain a clear picture to make a self- assessment that use industry-standard language can be adapted to the language laboratory procedures used in education.

3. The Influence of Inquiry Learning with Video Tutorials to Achieving Competence

Inquiry learning with video tutorials helping student competency achievement. The measurement of competence in the aspect of knowledge is based on the results of the written response test scores, while aspects of attitudes and skills measured by test scores response practices. Base on Figure 1. and Figure 2. the averages attainment of knowledge is 57.34 and the mean achievement of competence from the aspect of attitude and skill is

Figure 1. Achievement of competence knowledge

Figure 2. Achievement of competence attitudes and skills

Competence is an assessment of the knowledge, attitudes and skills that can be measured. The process of inquiry learning is done through a series of experiments that must be supported by an understanding theoretical concepts that get in the classroom. Learning lab is focused on achieving the competency of working attitude spawned standardized work culture and skills should be supported with reasonably sufficient of knowledge.

The data supporting the achievement of student competency can be measured through

a self-assessment on three units of competence, (1) MSL973002A prepare a working solution, (2) MSL974001A prepare, standardize, and use the solution and (3) MSL974003A perform tests and procedures. Assessment is done after the student attends inquiry learning process with the development of instructional video.

The achievement of competence on the third unit of competency is 78.52%. During the learning process lab, students are given learning tasks in preparing the working solution including set up, calibrate and use solution. The level of achievement in these units was 77.30% and 79.51%. Elements of competency has been achieved both on the competence units MSL973002A prepare a working solution is to use laboratory chemicals, glassware and equipment safely and make solution.

Learning outcomes showed competency elements that should be developed is to check the availability of the solution. As long as the learning process, students should always use fresh solution was made, resulting in learning activities, students can use the laboratory stock solution so as to have the opportunity to gain experience in checking the availability of the solution. Achievement of competency elements monitor the quality of solution in the laboratory on competence units MSL974001A prepare, standardize, and use the solution so the repair be developed learning modules are equipped with a procedure check and monitor the quality of solution.

The assessment results showed competency in setting up the unit, and use a standardized solution can be achieved either so it can be otherwise been competent in The assessment results showed competency in setting up the unit, and use a standardized solution can be achieved either so it can be otherwise been competent in

Students have to have a good achievement in the competence units MSL974003A testing and chemical procedures, which include elements of competence to interpret and schedule testing requirements, accept and prepare the sample, check the equipment before use, testing the sample to determine the type of substance or nature, process and interpret data, maintain a safe working environment, and maintaining laboratory records. The elements of competence to be improved is to interpret, determine testing requirements, as well as receiving and setting an example. Students get a sample from the laboratory and in module does not mention testing requirements and test sample preparation of students that necessary improvement modules and learning strategies.
