Abstract

Woven sacks made of plastic are used by various businesses. One of these business sectors that use plastic woven sacks is rice refining company. During this time, the quality of the resulting plastic woven products is still low and inconsistent. The Company experienced many problems with product defects caused by the production process. This is demonstrated by the large number of plastic woven sacks is not elastic, cannot withstand the load and tear. Troubleshooting for plastic woven products can be solved by QFD as a tool for identifying the need for good production process and connecting them with technical characteristics. The main focus of this method is to engage customers and experts in the product development process. Results of QFD would be used to improve product design. The results of this study indicate that the thread rolling process is a major cause of problems.

Abstract

Usaha Jahit yang berada di Kota Medan sangat berkembang dengan pesat. Hal ini disebabkan oleh tingginya minat masyarakat untuk menjahitkan bahan dasar pakaian sehingga akhirnya didapat sebuah desain yang sesuai dengan keinginan pelanggan. Demi mendapatkan ukuran dan desain yang susai tersebut, maka tiap usaha jahit harus menggunting kain sesuai dengan pola yang telah ditetapkan. Dalam proses kerja penjahitan, pemotongan pola merupakan bagian yang paling menentukan tingkat kesesuaian antara model pakaian dan hasil akhir berupa produk pakaian. Berdasarkan hasil observasi awal dengan mitra, mereka sering kesulitan pada saat proses pemotongan kain tersebut dikarenakan sempit dan terbatasnya ukuran meja potong kain. Dampak dari terbatasnya meja potong adalah pola kain yang digunting menjadi tidak sesuai dengan ukuran yang telah ditetapkan. Target yang telah tercapai adalah tersedianya meja potong ergonomis yang sesuai dengan dimensi dan ukuran tubuh pekerja sehingga dapat mendukung proses kerja jahit dan nantinya dapat mkeningkatkan kualitas produksi usaha jahit.

Abstract

Route distribution of a product constituting the order dismissal successive against branches and planning process from point of origin (a company) to the point of consumption (consumers) to fulfill its best customers turn. Pt. Xyz. Is the company in the sectors production snacks. Area their distribution over all the agent scattered in town medan. In medistribusikan of PT. XYZ sued for could design performance shipping reliable, while in fulfillment of a target there are still problems of companies are in distribution products. The process of product distribution in once product delivery only done to one retailing. Distribution products improper in determining route distribution to customers and without seeing former capacity of conveyance resulting in path traveled inefficient. This research berujuan to get route distribution by using centrifugal savings matrix that integrates any muaraangke supply facilities (csf) to distribution canter (d.c.) considering capacity conveyance and means of transportation owned company and to get route distribution efficient with optimize the mileage distribution minimize the use of conveyance; minimizing a charge required by the company and get time distribution feasiable. In distribution system beginning, PT. XYZ send to 14th outlet/day with the mileage 521,600 km and fund of rp. 847.600 and 5 fruit conveyance. By using the method saving matrix produce sub-division route less than route distribution company, applied where sub-division route proposal ' s 7 sub-division routes, produce a greater minimum with thrift distance of 193,7 km can save cost distribution rp. 309.725,- and matrix raise a total time distribution car conveyance of 1193,554 minutes with total car conveyance allocated about three units. Distribution system proposal can save distance of 37,1% and can save the transportation of 36,5 %.

Abstract

Distribution routes are distribution delivery routes that are created taking into account distance traveled, transport equipment capacity, and delivery capacity so that distribution costs are minimal. To date, there are 14 routes with 32 delivery points. Of the 14 existing routes, there are drop points through which several routes pass. So, companies need to evaluate the routes currently used. This problem arises as a result of the increase in shipping capacity over time. The general objective of this final research is to obtain alternative distribution routes in the process of distributing goods and analyze route improvements by comparing company routes and alternative routes obtained using the Saving Matrix and Clarke & Wright Savings methods. The research results showed that alternative distribution routes using the Saving Matrix method experienced an increase in costs of 5.4% from the original costs. Meanwhile, using the Clarke & Wright Savings method, distribution costs decreased by 3.6% per day. The improvement proposal given is an alternative distribution route using the Clarke & Wright Saving method, which has 11 routes and a savings of 3.6%.

Abstract

The economy was one factor the progress of a country. Each country competing to increase the productivity of the economy. Indonesia's economy ranks 17 world. Economic growth in Indonesia is very significant that was not separated from the role of small and medium enterprises (SMEs) that support the growth of exports and imports, one that can be seeded SMEs are SMEs manufacture of shoes. The role of SMEs that are so large and significant must always be maintained and developed to be able to compete in an era of global competition such as the implementation of the Asean Economic Community (AEC) in January 2015. Problems that interfere with the development and productivity of SMEs shoes, particularly around Medan city will be divided into 4 categories, namely: (1) human, (2) process, (3) facilities, and (4) Business competition. Based on this research, it is known that the most important issues that affect the development of SMEs in Medan shoe is its human resources. Solving these problems will be done with the Kaizen strategy (5S) which will be combined with the concept of training within industry (TWI) and the concept of P-Course. These improvements will result in strategies to increase the overall productivity of SMEs working with the primary focus is working and will evaluate the system works. This strategy is expected to fix the weaknesses of existing SMEs shoes, in order to face the global competition that will come.

Abstract:In the current modern era, the competitive situation of the manufacturing industry has increased and is very tight. The importance of production efficiency in a company is to increase revenue, which is the goal of every company by minimizing waste. One approach used to minimize waste is lean manufacturing. The study was conducted on a company that produces and markets products in the form of lamp posts on public roads and toll roads. The problem that often occurs in the manufacturing process of product items is that many production processes are not achieved according to the standard time set by the Company. In this study, a Lean Manufacturing analysis was carried out to improve the lamp post production process using the Value Stream Analysis Tools (Valsat) method. Based on this study, the type of waste waiting is the most dominant type of waste with a percentage of 19.55%. In second place is the type of waste overproduction with a cumulative percentage of 18.54% while waste motion is 17.32%. Based on the current state value stream mapping, the process cycle efficiency of the Hexagonal Lamp Post manufacturing process is 98%.  Keyword:Lean Manufacturing, Waste, Value Stream Analysis Tools, Process Cycle  Efficiency  Abstrak:Pada era modern saatinisituasipersainganindustri manufakturmengalamikenaikan dan sangat ketat.Pentingnyaefisiensiproduksidalamsebuahperusahaanadalahuntukmeningkatkanpendapatandimanahalinimerupakantujuansetiap perusahaandenganmemperkecilterjadinyawaste.
