Developmen of Guided Inquiry-Based Lab Manual for Practical Biochemistry II with Local Wisdom of Riau Approach

OKTRI . ANGGO

Abstrak


Based on the Indonesian government's policy demands for curriculum changes to improve Indonesia's human resources. The University of Riau made changes to the curriculum by implementing an integrated curriculum. But in fact the biochemistry practicum II lecture process at the FKIP UR Chemistry Education Study Program has not fully implemented the curriculum. Based on the findings of the field regarding biochemistry practicum II lectures, including:

(1) available practicum guidelines are verification,

(2) practicum guidelines do not use learning models or strategies,

(3) samples used do not utilize materials that are often found in daily life days,

 (4) do not utilize Riau's natural wealth as a source of learning,

(5) the absence of practicum guides specifically for lecturers or assistants to facilitate the lecture process, and

(6) existing practicum guidelines still guide students to do practicum by simply following procedures only in the practicum guide. In other words, it is necessary to develop a guided inquiry-based biochemical II practical guide with Riau's local wisdom approach to create more meaningful learning. The objectives of this study were:

(1) to produce guided inquiry-based biochemical II practicum guide with Riau's local wisdom approach on carbohydrate, lipid, protein, and fermentation material,

(2) test the feasibility of biochemical practicum guide II from development through expert validation and trial small group, and

(3) testing the effectiveness of biochemical practicum guide II on the results of development.

This research was conducted in several stages. The first stage is the process of developing a practicum guide. The development of biochemical practicum guide II uses the development model according to Thiagarajan (4D), namely the stages of defining, designing, developing and disseminating. After performing the stages of defining and designing, in the development stage, I obtained a biochemical II practical guide for students and specifically for dose or assistant. To obtain the feasibility of a practicum guide the results of the development are carried out expert validation. Based on data from the biochemical practicum guide II student validation results obtained an average score of 4.38 and a percentage of 85.93% with the feasibility criteria very feasible. While the data from the biochemical practicum guide II validation specifically for lecturers or assistants were obtained an average of 4.44 and a percentage of 88.84% with feasibility criteria as feasible. After the validation test is done, the practicum guide goes through the revision stages based on suggestions and input from the validator. In the small group trial data obtained an average score of 4.29 and the percentage of eligibility of 85.94% with the feasibility criteria very feasible. Based on the results of the small group trial, some suggestions and input were obtained, after revising the practicum guidelines it was said that it was worthy to be tested on a large group trial. Based on the results of a large group trial obtained data from the results of the classic N-Gain Score test showed an increase in understanding or mastery of student concepts by 0.59 in the medium category. To test the effectiveness of the practicum guide the results of the development required data on the average accumulation of the final grades of students, namely with a value of 77.81 and 100% pass statement. Based on these data, it can be concluded that the results of the development of biochemical practicum guide II meet the effectiveness criteria according to Djamarah (2010) and are classified as very effective criteria according to Arikunto (2010).

 

The results showed that (1) the results of the development in the form of biochemical practicum guide II specifically for students and biochemistry practicum guide II specifically for lecturers or assistants, (2) based on the results of validation tests of biochemistry practicum II specialists for students and practicum guides specifically lecturers or assistants and the results of small group trials show that the practicum guide is very feasible to use, and (3) student learning outcomes show the N-Gain score on the criteria of being. Based on the effectiveness criteria according to Djamarah (2010) and the effectiveness criteria according to Arikunto (2010) practicum guidelines the results of development are classified as very effective categories. Some suggestions that need to be considered at the time of the large group trial is the need for supervision of the practitioner so that there are no mistakes during the practicum, such as the use of tools that are not in accordance with their functions, not practicing the agreed practice procedures, and there are less students play an active role in carrying out lab work.
