Abstract

This study aims to develop a Student Worksheet based on Higher Order Thinking Skills (HOTS) by using the Problem Based Learning model on the Sine and Cosine Rule learning material for class X high school students. The quality of the Student Worksheet refers to the validity of the Learning Implementation Plan and the Student Worksheet. Research and Development (RD) research type is used in this study. In this case, the development of the research refers to ADDIE development model, there are only 3 stages that are limited to the development stage only applied in the research development of Student Worksheet based on HOTS. The subjects in this study were high school student Worksheet Assessment sheet to measure validity. Based on validation that has been conducted, it was obtained that student worksheet based on HOTS developed with a Problem Based Learning model have valid criteria; Student worksheet based HOTS on the Sine and Cosine Rules learning material which was developed using Problem Based Learning model declared to have valid criteria with an average score 4,1 with a very predicate.

Abstract

This study aims to: 1). Determine the level of validity, the effectiveness, and practicality of student worksheets developed with the learning model problem-based learning class XI in SMK, 2). Find out increase the learning interest of the students of class XI SMK after using students' worksheets with the model of problem-based learning. The research type used is Research and Development refers to model 4-D, namely define, design, develop, and disseminate. However, in this study, the research development worksheet using problem-based learning is modified bounded only at the stage of development. Subjects in this study were students of class XI business management of SMK Budi Utomo Cikampak. Instruments of assessment used are a validity questionnaire, a test of interest in learning, and a student responses questionnaire. The results obtained that the worksheet has been developed to meet the criteria of validity with an average score of 4.2 in the valid category. Mastery learning in the classical style has been experiencing an increase in trial I (59,09%) in trial II increased by (90,90%) with the learning time does not exceed the usual learning, the student worksheet has been effective. Student Worksheet has been developed to meet the criteria of practicality review of the questionnaire responses of students to the shows that the average score 81,76% with the strong category. (2) the learning Interest of students has increased, namely with an average increase from the pretest to the posttest with a score increase of 80.5% with a high category.

Abstract

This research was conducted using data obtained from UD Kreasi Lutvi. Meanwhile, based on the results of production optimization processing using Table Simplex and QM For Windows V3, production levels show different levels of production, namely 80,000 large packages, 5,000 medium packages and 400 small packages. When UD Kreasi Lutvi produces according to optimal conditions, the profit that can be obtained under optimal conditions is Rp. 386,600,000, while the profit in factual conditions is Rp. 361,268,000, so the increase in profits is Rp. 25,332,000. This shows that the benefits in factual conditions and optimal conditions are much different, but to increase profits, UD Kreasi Lutvi must produce according to optimal conditions.
