Abstract

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

Abstract. This research is a learning device development research that will be used in learning with the Project based Learning (PjBL) model with the help of technology, in this case using Geogebra software. Geogebra Software is a dynamic mathematical software that combines geometry, algebra and calculus can be used as a tool in mathematical learning. Geogebra is a special mathematical program that can be used as a medium for learning mathematics. This research was conducted in one of the high schools in Deli Serdang Regency. Development of learning is done gradually in accordance with step 4D, then the researchers simplify the changing of the four stages (4D) into three stages (3D) is defining, designing, and development.Keywords: Teaching Materials, Project Based Learning (PjBL), Geogebra Software

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.
