PT. RXZ merupakan perusahaan yang bergerak di bidang manufaktur, khususnya di bagian infrastruktur. Salah satu faktor produksi yang harus dioptimalkan penggunaannya seperti yang terjadi pada PT. RXZ yaitu mesin produksi. Dewasa ini mesin yang digunakan dalam kegiatan produksi harus mampu beroperasi dengan optimal. PT. RXZ menggunakan konsep breakdown maintenance yaitu melakukan perawatan setelah mesin mengalami kerusakan. Metode tersebut mengeluarkan biaya perbaikan yang sangat besar karena harus mengganti komponen yang rusak dengan komponen yang baru. Tujuan penelitian ini adalah untuk membandingkan konsep breakdown maintenance yang digunakan oleh perusahaan dengan konsep preventive maintenance. Metode yang digunakan dalam penelitian ini adalah preventive maintenance dengan pendekatan Modularity Design. Modularity Design berfungsi untuk mengelompokkan elemen-elemen mesin sesuai dengan urutan proses perbaikan mesin. Pemakaian konsep ini dapat menekan biaya produksi dan proses perbaikan lebih sederhana. Hasil yang didapatkan adalah biaya perawatan mesin dengan menggunakan preventive modularity maintenance menghasilkan total biaya perawatan yang lebih kecil yaitu sebesar Rp 49.902.964 dibandingkan dengan biaya perawatan breakdown yang total biaya perawatannya mencapai Rp 55.071.518. Persentase perbandingan modularity design lebih kecil 9,38% dari breakdown maintenance sehingga metode ini tepat digunakan oleh perusahaan.

Penentuan prioritas pusat distribusi merupakan kegiatan strategis dalam supply chain management yang dilakukan oleh PT. XYZ dalam rangka peningkatan produktivitas dan efisiensi perusahaan. Adapun kendala yang dihadapi perusahaan dalam hal ini, yaitu tidak optimalnya pendistribusian produk di pusat-pusat distribusi, antara lain wilayah Medan, Brastagi, Aceh, Pekanbaru, Jambi, dan Jakarta. Jumlah permintaan dan pangsa pasar yang bervariasi dari setiap pusat distribusi menyebabkan kelebihan dan kekurangan persediaan di pusat-pusat distribusi milik perusahaan. Oleh sebab itu, dibutuhkan pengambilan keputusan terhadap prioritas pusat distribusi guna mengoptimalkan pendistribusian produk. Maka, pengambilan keputusan dilakukan dengan metode DEMATEL (Decision Making Evaluation and Laboratory) dan pembobotan prioritas akhir dengan melibatkan metode Analytical Hierarchy Process (AHP). Balanced Scorecard diusulkan untuk mengidentifikasi kriteria yang mempengaruhi penentuan prioritas pusat distribusi. Berdasarkan hasil penelitian, terpilih 18 kriteria yang dirangkum dan dikelompokkan berdasarkan perspektif balanced scorecard, yaitu finansial, costumer, internal, dan learning & Growth. Hasil pengolahan dengan menggunakan metode DEMATEL diperoleh hubungan antar kriteria pada masing-masing perspektif. Hasil analisis terhadap pusat distribusi diperoleh nilai pembobotan untuk pemrioritasan distribusi secara berurutan yaitu 0,3396; 0,2233; 0,1541; 0,1101; 0,1007; 0,0722.

Changes in human mindset along with the development of technology, trends and the need for quality products increasingly require the development of more complex product functions to meet the expectations and needs of consumers as users of the product. Merging several functions in a single product is often become the main focus for managers in research and product development departments to produce product design concepts in the present. The success of a product can be measured by how much the existence of the product can be accepted by the consumer so as to increase profit for the company or producer. Product design is an idea, concept development, testing that done before the production process of an object or product is done. The product designer evaluates the ideas and realizes them through the product. The design of products to be made in this research is multifunctional tissue box. Ideas for product design are obtained through brainstorming. The next step is to make a questionnaire based on the results of brainstorming to obtain information and know the consumer requirement for the product. In designing the tissue box, clarifying objectives is done in the form of objective trees and the functional analysis in the form of block diagrams. Then Quality Function Deployment is done to improve product quality based on consumer needs. Alternative generation with Morphological Chart is done to achieve solutions to product design problems. There were 4 alternatives with relative importance value for alternative 1 = 4.8719; alternative 2 = 3.7723; alternative 3 = 3.4941 and alternative 4 = 2.8785.
