Abstract

Injection molding is a machining process that can form plastic-based objects in bulk and quickly. Some of the problems encountered in injection molding machines are long cycle times. This hampers the production rate. Several parameters to be analyzed for cycle time and net are injection speed, injection pressure, and holding pressure. Optimization of values for injection speed, injection pressure, and holding time is done to get the fastest cycle time and the lightest net product. The analysis process in this study uses the Response Surface method. The experimental design used was Box-Behnken with ANAVA to analyze the data. From the research conducted, it can be concluded that the injection speed parameter is a parameter that has a strong influence on cycle time, this is evidenced by the value of the injection speed tcount greater than the t table. Meanwhile, of the three parameters studied, individually did not affect the net response. The configuration parameters that produce the optimal value are the injection speed of 25 m / s, the injection pressure of 1586.8687 bar / kN, and the holding pressure of 1000 bar / kN. From this configuration, the cycle time value is 41.92 seconds and a net value is 4.739 grams.

Abstract

Damage on FRP Ships in Indonesia is quite common. Damage was often occurs in the hull-deck joint area.The hull-deck joint of the FRP ship is an important thing in reference to the quality and structural strength of the FRP ship. Currently, researchers research about hull-deck joint method of FRP ships in order to obtain the proper joint method and result of joint according to the material and use of a structure.An example of a joint method that is often used especially in composite materials is the adhesive joint method. In the adhesive joint method, the right type of adhesive is a very influential part of the structural strength of a joint. This final project is focused on analyzing and comparing several joint designs for FRP material where examples of its application are on the hull and deck joints of FRP ships to find out which design are the best structural strength using ANSYS software. The simulation results of 45,000 N load shear stress obtained a shear strength value of 470.60 MPa for designs with epoxy film(design 1), 470.69 MPa for designs with epoxy(design 2),and 470.72 MPa for designs with a polyester(design 3). Through manual calculation and analysis, the joints with polyester are best.

Abstract

Keterlambatan adalah suatu permasalahan yang sering terjadi di dunia industri. Keterlambatan yang dimaksud dalam hal ini yaitu keterlambatan terselesaikannya suatu proses produksi sesuai dengan tanggal deadline yang telah ditentukan dan disepakati kedua belah pihak. Dalam penelitian ini metode yang digunakan untuk mengatasi masalah keterlambatan yaitu Metode Lean Six Sigma. Tujuan dari penelitian ini yaitu mengatasi masalah keterlambatan dengan mengidentifikasi serta menganalisa jenis – jenis pemborosan atau waste yang terjadi selama proses produksi berlangsung. Adapun yang akan dijadikan objek penelitian ini adalah mould inhaler barrel. Output yang akan dihasilkan dari penelitian ini yaitu dengan memberikan usulan perbaikan terhadap perusahaan sebagai pertimbangan dalam menentukan kebijakan untuk mengatasi permasalahan yang berkaitan dengan keterlambatan yang terjadi pada saat proses produksi berlangsung. Dari hasil penelitan yang dilakukan dengan menggunakan beberapa cara untuk mengidentifikasi waste didapatkan hasil bahwa waste waiting adalah waste kritis dalam proses produksi mould inhaler barrel. Dibuktikan dengan hasil pembuatan diagram VSM yang diketahui terdapat kegiatan menunggu sebelum ke proses Milling, kemudian dengan pengelompokkan VA dan NVA didapatkan hasil NVA sebesar 27,24% dengan total waktu sebanyak 947,13 menit dalam satu kali proses produksi sedangkan dalam metode pembobotan kuesioner diketahui yang menjadi peringkat pertama yaitu waste waiting. Dengan menggunakan metode fishbone diagram didapatkan 5 faktor penyebab terjadinya waste waiting yaitu faktor manusia, faktor metode kerja, faktor mesin, faktor bahan baku, dan faktor lingkungan kerja. Usulan perbaikan yang didapatkan dari penelitian ini salah satunya membuat kontrak kerja mengenai keterlambatan pengiriman raw material ke perusahaan dari suplier, menjadi usulan perbaikan yang berdasarkan perhitungan peringkat RPN merupakan permasalahan yang harus segera dilakukan perbaikan.

Abstract

Laser cutting machine is able to cutting hard material and having complicated patterns. In the cutting process in the laser cutting machine has several parameters, they are the laser beam focus point, cutting gas pressure and cutting speed. These parameters can cause cutting defects. Starting from the roughness surface until the product is not cut. So we need an optimization process through research methods. The optimization method in this research use the L9(34) orthogonal matrix with 3 levels on each parameter of taguchi and neural network prediction. From the taguchi optimization process, it produces an optimal parameter combination for the surface roughness response at the laser beam focus point -14 mm, gas cutting pressure 17 bar and cutting speed 0.4 m / min. And for the response of the cutting rate at the laser beam focus point -17 mm, gas pressure cutting 20 bar and cutting speed 0.6 m / min. While the optimal parameter settings using a neural network, for the response of surface roughness at the laser beam focus point -14 mm, gas pressure cutting 20 bar and cutting speed 0.2 m / minute. And for the response of the cutting rate at the laser beam focus point -20 mm, gas pressure cutting 17 bar and cutting speed 0.6 m / minute. In optimal parameter settings using the taguchi method, the laser beam focus point parameters have the greatest contribution, with a percentage of 46.5061% for the response of surface roughness. While cutting speed has a significant contribution in reducing the variation of the cutting rate response, with a contribution percentage of 66.0430%.

Abstract

Determining the combination of machining parameters is very important. The right machining parameters can produce optimal machining performance. EDM sinking is used to produce automotive components, aerospace, molds, and dies. AISI P20 is material that is widely used by manufacturing industry for dies and mold because of its hardness and resistance to heat. Based on these reasons, optimization is carried out to get appropriate parameter combination for the EDM sinking process using AISI P20. Process variables in this study are type of electrode, gap voltage, on time, and off time which aims to produce optimal response. Response variables observed were material removal rate, surface roughness, and electrode wear rate. Based on Taguchi method, matrix orthogonal L18 (21 × 73) was chosen for design of experiment. Taguchi method and Grey Relational Analysis used to optimize multiple responses simultaneously. Parameter optimum condition could be obtained by using graphite and setting values of gap voltage 50 volt, on time 250 ?s, off time 40 ?s. Percentage contribution of electrode type is 39,0733% whereas off time give contribution 32,4311%, on time 6,4574% and gap voltage 4,3590%.
