Abstract. Production activity as a part of corporate organizational functions is responsible for the processing of raw materials into finished production that can be sold. Increased efficiency in production is one way that can be done by the company in order to always be able to meet consumer demand. UD.Putih Jaya is an enterprise engaged in the production of paving. In the production process the company has never made a measurement of the efficiency of the production process that has been done. Measurement efficiency of production processes in this study will use a measuring instrument in the form of method Data Envelopment Analysis (DEA). DEA model used is Primal CCR model. Primary CCR is used to determine which UPK (Decision Maker Unit) is efficient and inefficient. From the calculation results obtained that UPK 1, UPK 2 and UPK 4 is an efficient UPK UPK 3 and UPK 5 into the category of inefficient UPK.Keywords: data envelopment analysis, production, efficiencyAbstrak. Aktivitas produksi sebagai suatu bagian dari fungsi organisasi perusahaan bertanggung jawab terhadap pengolahan bahan baku menjadi produksi jadi yang dapat dijual. Peningkatan efisiensi di bagian produksi merupakan salah satu cara yang bisa dilakukan oleh pihak perusahaan agar selalu dapat memenuhi permintaan konsumen. UD.Putih Jaya merupakan suatu usaha yang bergerak dibidang produksi pembuatan paving. Dalam proses produksinya perusahaan belum pernah melakukan pengukuran efisiensi dari proses produksi yang telah dilakukan. Pengukuran efisiensi proses produksi pada penelitian ini akan menggunakan suatu alat ukur berupa metode Data Envelopment Analysis (DEA). Model DEA yang digunakan adalah model CCR Primal. CCR primal digunakan untuk menentukan UPK (Unit Pembuat Keputusan) mana yang efisien dan tidak efisien. Dari hasil perhitungan didapatkan bahwa UPK 1, UPK 2 dan UPK 4 merupakan UPK yang efisien sedangkan UPK 3 dan UPK 5 masuk dalam kategori UPK yang tidak efisien.Kata Kunci: data envelopment analysis, produksi, efisiensi

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.

Abductive reasoning is a problem-solving method that allows for the creation of hypotheses based on incomplete information. In this article, we explore the potential of using abductive reasoning to help solve algebraic problems. We begin by providing an overview of abductive reasoning and its key features. We then present a case study in which we apply abductive reasoning to a specific algebraic problem. Our results demonstrate the effectiveness of using abductive reasoning to generate new hypotheses and ultimately solve the problem. Finally, we discuss the implications of our findings for the teaching and learning of algebra, as well as potential future research directions in this area. Based on several observations, some students experienced difficulties in problem-solving activities. Their inability may be caused by the complexity of making conclusions from the facts provided in problem-solving. Student failure in problem-solving shows that the importance of problem-solving needs to be better taught in learning mathematics. One prominent factor that can support problem-solving in practice is reasoning. Therefore, increasing reasoning and proof is a fundamental aspect of learning mathematics. Theoretically, and developing Abductive Reasoning as teaching material for Linear Algebra courses to find solutions to algebraic problems in mathematics learning activities.

Mathematics is one of the supporters of the development of science and technology. The low creative thinking of students is one of the causes of students' lack of interest in learning mathematics. The assumption for most students that mathematics is a very heavy and difficult subject, especially in solving Geometry Transformation problems. The purpose of this research is to improve students' creative thinking skills through the development of project-based learning models assisted by geogebra software and the effectiveness of these learning models. This development uses the ADDIE (Analysis, Design, Development, implementation and Evaluation) model. The trial was conducted in class XI TKJ SMK N 1 Penanggalan, Penanggalan District, Subulussalam City, Aceh Province. The results showed that in the first trial there were 12 students who completed with 60% and 8 students did not complete with 40% so that they could not meet the effective criteria. In the second trial there was an increase in creative thinking skills for students who completed as many as 18 students, 85.7% and students who did not complete as many as 3 students, 14.3%. So that the development carried out in the second trial showed an increase in students' creative thinking by 25.7%.
