Abstract

This research is an R & D (Research and Development) which aims to see the validity and responses of students to Student Worksheets based on guided inquiry on buffer solution materials. This research development procedure adopts the Borg and Gall models until the seventh stage. This study involved three validators, one validator, a media / design expert, and two material experts. Small and medium scale trial subjects were students of MA Nurul Huda Sukaraja. The data instrument used validation sheets, student response questionnaires, and new interviews. The results showed that the chemical LKPD based on tobacco inquiry on the buffer solution, the proportion of design experts / media was 85.41% with a very valid category, and the proportion of tenacity obtained from two material expert trainers was 98.29% with a very valid category. The proportion of the average value of the three validators is 88.98% with the very valid category. Student responses to the developed chemistry worksheet can be categorized as very interesting, where small-scale trials get a proportion of 96.72% with a very attractive category, in the medium-scale trial the proportion is 89.34% and is stated to be very interesting.Key words: LKPD, guided inquiry, buffer solution.

Abstract

Chemistry is a subject that is closely related to learning that requires students to be active in problem solving. Because of this, a worksheet development is needed to support chemistry learning activities. This study aims to develop a Student Based Worksheet (LKPD) based on Problem Based Learning (PBL) hydrolysis material to improve mathematical logical intelligence. The quality of LKPD is measured by the criteria of validity, effectiveness, and practicality in the learning process. The development model used in this study is a 3D model (define, design and develop). Data analysis techniques using qualitative and quantitative tests. The product development validation was carried out by the validator of media experts and material experts, while the trial was conducted by 36 students of class XI IPA 5. The results of the validator analysis stated that the quality of learning material was included in the excellent category with a percentage of 93.77% of the material experts and 94.46% of media experts. The effectiveness of LKPD indicated an increase in mathematical logical intelligence of students with the achievement of N-gain of 0.56 in the medium category and classical completeness of 86.11%. Student responses to the practicality of using LKPD showed results of 77.78% which included in the very good category and 22.22% included in the good category. Based on the results obtained, it can be concluded that LKPD fulfills valid, effective, and practical criteria to improve mathematical logical intelligence.
