Abstract

Penelitian ini membahas mengenai proses produksi yang tidak terkendali sehingga menghasilkan produk dengan kualitas di bawah standar. Kondisi yang tidak sempurna dapat terjadi karena adanya kesalahan inspeksi/pemeriksaan. Selain itu, sistem produksi yang tidak sempurna juga dapat diakibatkan oleh deteriorasi mesin. Deteriorasi terjadi akibat penurunan kinerja mesin sehingga menghasilkan produk nonconforming. Semua produk yang dihasilkan akan mengalami proses inspeksi. Produk yang baik akan langsung diterima sedangkan produk nonconforming akan dilakukan proses rework, dan setelah proses rework produk tersebut akan diterima. Pada penelitian ini dilakukan pengembangan model optimisasi lot produksi dengan mempertimbangkan sistem produksi yang mengalami deteriorasi dengan kriteria minimisasi total ongkos yang terdiri atas ongkos set-up, ongkos produksi, ongkos pengendalian kualitas, dan biaya penalti. Kata Kunci: deteriorasi, rework, produk nonconforming, lot produksi   ABSTRACT This research discuss concerning the production of uncontrolled so as to produce products with the qualities of substandard. Condition of being imperfect can occur because of error inspeksi/examination. Besides, production system imperfect can also caused by deterioration machine. All products resulting will undergo a inspection. Products well be were accepted by the product nonconforming will be done process rework, and after the rework that product will be welcome. On the study is done development model optimisasi lot production with consider production system which had deterioration with criteria minimisasi total cost consisting of fare set-up, the production costs, fare control quality, and charge penalty. Keywords: deterioration, rework, nonconforming product, production lot

Abstract

Background of the research is not yet providing the media emphasis on the aspect of learning to think chronologically. This research aims to: 1) Developing media DGBL viable and practical learning in history. 2) Reveal the effectiveness of media Digital Game-based Learning (DGBL) in improving the chronological thinking ability of students. This development research using model ADDIE (Analyze, Design, Development, Implementation, and Evaluation). The subject of the trial consists of 29 SMAN 1 Padang Panjang of Class XI of SCIENCES 6. The eligibility test is done through assessment of expert material and 2 media expert. In addition, the test is also done by two people the practicalities of history teachers and 29 students to see the practicality of DGBL media. The results indicate that the feasibility of the development of media based on expert assessment of materials, techniques and instruments of data collection, and data analysis to Digital Game-Based Learning (DGBL) is well worth the use (average score of 4.18 research), while According to a feasibility assessment of media experts that the media very worthy DGBL used (average score of 4.26). Research products are effective in improving students ability to think chronologically with n-gain 0.67 (categorize your medium). Product Media DGBL rated very practical by teachers and students (mean score 4.68 and 4.6).
