Abstract

PT Sarana Energi Investama operates as an industry in the field of electrical components. Some of the products produced by PT Sarana Energi Investama include LVMDP panels, sub-distribution panels, Lighting panel, Emergency panel, Elevator panels, and others. In this case, the layout owned by PT Sarana Energi Investama is still non-standard in nature and was placed without taking into account the flow of production as well as the frequency and relations between production facilities. In this case, research was conducted regarding the design of the facility layout at the workshop facility owned by PT Sarana Energi Investama using the group technology layout. Group technology layout is considered one of the methods that can be used to design layouts in an effective, efficient, and flexible manner for customized product types and is able to overcome production constraints when the quantity of demand fluctuates. In the study, calculations were carried out using routing sheets, calculating the frequency of transfers, determining relationships between facilities, using rank-order clustering algorithms to design group technology layouts, as well as designing intracellular and overall facility layouts. Based on this research, using the proposed layout can increase the efficiency of moving distances by 40.74%, moving time by 31.25%, and material handling costs by 31.25% within a month.

Abstract

Perkembangan yang terjadi membentuk sebuah lingkungan industri yang dinamis, dimana terdapat jenis produk yang bervariasi dan fluktuasi volume produksi. Kelemahannya dalam meminimumkan jarak perpindahan material menyebabkan tata letak tradisional menjadi tidak efisien untuk digunakan, sehingga diperlukan sebuah rancangan tata letak yang mampu mengatasi kelemahan tersebut serta strategi dalam mengembangkan tata letak, yakni dari tradisional menjadi non-tradisional. Pada penelitian ini digunakan dua perusahaan berbeda, yakni PT. X menggunakan tata letak produk dan PT. Y tata letak proses. Penelitian ini memberikan perhitungan dan analisis tata letak dengan metode rectilinear untuk kriteria jarak, Material handling planning sheet (MHPS) untuk kriteria waktu dan biaya material handling. Hasil yang didapatkan tata letak proses adalah 1.586,36 meter, 175,9967 menit dan Rp 70.423,75 sedangkan hasil yang didapatkan untuk tata letak produk adalah 1.154,97 meter, 415,2947 menit dan Rp 167.403,4. Hasil perhitungan tersebut dibandingkan dengan tata letak non-tradisional, yakni tata letak selular dan tata letak Modular. Hasil dari penelitian menunjukkan bahwa tata letak Modular mampu mengurangi Jarak sebesar 45,12%; Lama waktu 24,74% ; dan biaya 27,74% dari tata letak proses. Sedangkan hasil yang didapatkan tata letak seluler mengurangi Jarak sebesar 8,35%; Lama waktu 2,393% ; dan biaya 2,393% dari tata letak produk.. Dengan demikian dapat disimpulkan bahwa tata letak non-tradisional yang baik sebagai peralihan dari tata letak proses adalah tata letak Modular, sedangkan untuk tata letak produk adalah tata letak selular

Abstract

PT. XYZ is a manufacturing company which produced a variety of products with uncertain demand. All of the products made of Polyurethane. This company plans to expand their production floor at the 1st floor to accommodate the machines at the 2nd floor. The reason for this expansion was because the operators have to go to the 2nd floor if they want to produce some small-sized products, which increases the material flow on the production floor. Furthermore, the ovens located only at the first floor, causing the flow to increase even more. If all the machines are at the same floor, the material flow will decrease. The purpose of this research is to propose layout design, which can reduce the distance between machines. This research using quantitative and qualitative approach. Quantitative approach uses ABSMODEL 3 algorithm, while qualitative approach uses CORELAP method. This final proposal also considers some other areas, which is Quality Control and finishing area including racks for finished products. These two approaches compared in order to know which one generates the shortest distance, where the better result turned out the one using quantitative approach with the total distance of 80,67 m.

Abstract

PT. Karya Utama Pratiwi is a company that produces socks from yarn to socks. This company has two parts: the manufacture of socks and the heating section. There are still manual processes in the heating section, or there is still much human intervention. On the contrary, what happens in the sock-making section, which has many machines. The problem that occurs today is that the achievement of production targets is not always achieved, namely as many as 520 finish goods (18720 socks), so the root of the problem is sought. It was found that the production capacity measurement was never carried out, so it becomes the background of research in this study to measure production capacity in the heating section. Capacity measurement begins with measurements at each work station using a predetermined time standard system by paying attention to work movements using the MTM-1 method as input to the ProModel. Initial system simulation results produced an average of 478 in 30 replications. In addition, there are entities experiencing login delays of 10.36 and 21.20 minutes. In some locations, it was seen that they experienced idle time. For example, the oven was 56.97%, above 50%. So, there need to be improvements in order to achieve the target. These things become the basis for making SOPs achieve targets; SOPs are designed and run with ProModel simulations based on possible assumptions. Based on the SOP simulation results, increase production by 2% from the maximum initial simulation conditions from 579 to 594. SOPs will help meet targets and are well executed.

Abstract

This research discusses the proposed implementation of lean manufacturing system at PT. MONIER. PT.MONIER is a manufacturing company engaged in the production of tiles with 3 types of product that is Exeltile, Centurion tile and Elabana tile. PT. MONIER is using push system as their production system methodat the moment. Current state value stream mapping is made to see shop floor as a big picture. Calculationshows that current state Process Cycle Efficiency (PCE) is very low with only 4,51%. The company still farfrom “lean” because minimum requirement of a company called lean when the value of PCE more than30%. Meanwhile, current state Overall Equipment Effectiveness (OEE) is 79,98%. From the observation, itcan be found that there are many non-value added activity (waste) at PT. MONIER factory. From theidentification of waste using check sheet and cost calculation resulted by wastes, it was found that inventorywaste post the biggest cost with 92,8% of the total cost of existing waste. With further analyze, it is knownthat the root cause from inventory waste is due to the company allow overproduction and there is wrongphilosophy against inventory. Those root causes which has found before is to be eliminated with leanmanufacturing system approach. There are several methods that will be applied in PT. MONIER such as 5Simplementation and standarized work, then future state value stream mapping is made to see all proposedmethods in a big picture. In addition, this future state condition will be simulated to give a betterperspective. With the implementation of lean manufacturing system, future condition is as same as currentstate value condition. Future state Process Cycle Efficiency (PCE) is 4,51% and future state OverallEquipment Effectiveness (OEE) is 79,98%. This happens because the theory and methods of lean from leanmanufacturing system can only be applied on the assembly line and one piece flow.

Abstract

The purposes of this research is to analyze the optimal distribution system at PT. X. There are three alternatifs given. The method used is saving matrix method and Knapsack using distance and time data. This research is considered the traffic conditions so the distance matrix is transformed into time matrix. The result show the distribution route and sequence of optimal methods. Distribution route is obtained using Farthest Insert, Nearest Insert and Nearest Neighbor. The sequence of methods is placed saving matrix method at first and then Knapsack or vice versa. After this, the distribution cost is calculated for three alternatifs given. This cost calculation is considered pinalty cost which is the value of opportunity cost when truck is not fully used. The results of cost calcutation show, when considered penalty cost, the best alternatif is alternatifs three that deliveries all consumer demand with freight forwarding services. However, this penalty charge is not real value (not spending money) so the company does not consider the cost of this penalty. When calculating cost without penalty cost, the best alternatif is alternatif one that deliveries all consumer demand with the company’s truck. In the first alternatif, the best method is saving matrix distance – knapsack. This method aims to select nearby consumers then optimize the distribution fleet.

Abstract

PT. XYZ merupakan sebuah perusahaan manufaktur yang bergerak dibidang otomotif dan sudah berjalan sebagai supplier komponen otomotif untuk beberapa perusahaan otomotif terkemuka di Indonesia. Kebanyakan proses produksi pada PT. XYZ sudah berjalan dengan baik. Tetapi terdapat salah satu sub produk mereka yang memiliki kendala dalam proses produksinya yaitu muffler K-59J. Pada lintasan produksi muffler K-59J dinilai kurang optimal dalam proses produksinya. Hal tersebut dilihat dari banyak kendala yang timbul selama proses produksi berlangsung. Mulai dari terjadi penumpukan (bottleneck), Target produksi harian sering tidak tercapai sehingga sering terjadi waktu kerja tambahan (overtime), dan jika dilihat secara data nilai efisiensinya hanya sebesar 58,81 %. Dengan demikian, penelitian ini bertujuan untuk meningkatkan performa dari lintasan produksi tersebut. Oleh karena itu diusulkan metode Algoritma Genetik yang bersifat komputerisasi untuk meningkatkan performanya. Proses penyelesaian penelitian ini dilakukan dengan bantuan program matlab dalam pengerjaan metode Algoritma Genetik. Pada prosesnya, dilakukan beberapa tahapan mulai dari membuat representasi genetik, menyeleksi populasi induk, melakukan rekombinasi dan mutasi, dan regenerasi populasi. Tetapi terdapat sedikit perbedaan pada penlitian ini dimana populasi awal yang dibentuk merupakan populasi yang sudah tersaring kedalam syarat-syarat keseimbangan lintasan antara lain sesuai dengan diagram alurnya, dan jumlah waktu stasiun kerja tidak melebihi cycle time. Dari hasil pengerjaan metode Algoritma Genetik tersebut, didapatkan besar efisiensi lintasan sebesar 74,07 % dengan total stasiun kerja sebanyak 18 stasiun kerja. dengan demikian nilai efisiensi lintasan berhasil ditingkatkan sebesar 15,26 %.
