Abstract

East Java province is one of the rice granary and is an important national food buffer. In 2014, East Java targeted to contribute 60% of 10 million tons national surplus in P2NB program. Objective of this research is to predict rice availability in 2013 to 2020 and analyze East Java readiness on achieving the target. Research steps starts from cause-effect diagram, stock and flow diagram, math formulation inside the diagram, verification and validation of the model, and simulation of developed model. Result of dynamical system indicates availability of rice in 2014 is 3,944,377.7 tons. With such availability, East Java target to contribute 60% of 10 million national rice surplus in 2014 cannot be achieved.

Abstract

Penelitian ini bertujuan menerapkan konsep Six Sigma untuk mengurangi terjadinya cacat dan menekan adanya variabilitas yang terjadi pada proses pembuatan keramik. Proses perbaikan dilakukan secara sistematis dan kontinyu dengan menggunakan siklus DMAIC (Define, Measure, Analyze, Improve and Control). Dengan menggunakan diagram Pareto diperoleh dua jenis cacat kritis yang menjadi permasalahan utama yaitu retak dan bintik melepuh. Selanjutnya alternatif-alternatif perbaikan pada proses diperoleh dengan FMEA. Berdasarkan nilai Risk Priority Number (RPN) yang tertinggi diambil 3 alternatif perbaikan dan selanjutnya dipilih satu alternatif terbaik dengan menggunakan metode AHP. Implementasi perbaikan dilakukan dengan menggunakan timer dan menugaskan operator khusus pada saat pembakaran untuk mengurangi cacat retak dan membersihkan kotoran bodi dengan menggunakan kompresor untuk mengurangi bintik melepuh. Setelah dilakukan evaluasi hasil implementasi alternatif perbaikan pada proses pembuatan keramik diperoleh kenaikan level sigma dari 2,8 menjadi 3 yang diikuti penurunan DPMO dari 104.167 menjadi 65.625. Sedangkan prosentase biaya akibat kualitas keramik yang jelek (COPQ) terhadap total penjualan mengalami penurunan dari 16,48% menjadi 9,93%.

Abstract

CV. Mebel Bima merupakan sebuah perusahaan yang bergerak dalam bidang pengerjaan kayukhususnya pembuatan berbagai model daun pintu dan kusen. Tipe aliran produksi di perusaaan adalahjob shop dikarenakan pengerjaan setiap job memiliki aliran yang berbeda di setiap mesinnya.Penjadwalan produksi di perusahaan adalah diurutkan berdasarkan total waktu penyelesaian jobterlama sampai yang terkecil. Permasalahan di perusahaan selama ini adalah besarnya makespan yangdihasilkan oleh penjadwalan dengan metode perusahaan sehingga perusahaan mengalami keterlambatanpenyelesaian job dari waktu yang sudah ditetapkan sebelumnya. Berdasarkan masalah tersebutpenelitian ini bertujuan untuk menentukan urutan pengerjaan job dengan makespan yang lebih kecilmenggunakan algoritma jadwal non delay dengan prioritas SPT. Tahap-tahap dalam penelitian iniadalah dimulai dari observasi langsung di perusahaan, studi literatur, perumusan masalah, pengambilandata, pengolahan data, dan terakhir adalah pembandingan hasil penjadwalan. Metode penjadwalanproduksi yang digunakan di perusahaan menghasilkan makespan sebesar 194,4 jam atau 25 hari kerja (1hari terdapat 8 jam kerja), sedangkan usulan penjadwalan dengan menggunakan algoritma jadwal nondelay menghasilkan makespan sebesar 168,79 jam atau 22 hari kerja, dengan demikian Penjadwalandengan menggunakan algoritma jadwal non delay dapat menghemat total waktu pengerjaan sebesar24,85 jam atau 3 hari kerja lebih 0,85 jam.

Abstract

Vehicle routing problem with simultaneous pickup and delivery (VRPSPD) is a problem of vehicle routes where the delivery and pickup of products to each consumer is conducted simultaneously. Pangkalan Agisindo Alam Mandiri is engaged in the distribution of 3 kg LPG. At present,pangkalan already has a schedule of visits to retail stores, but the visit route is still subjectively set which causes long mileage and high transportation costs. The problem of determining the route at this pangkalanis calledVRPSPD because pangkalandelivered filled  LPG tubes to retail stores and at the same time picked up empty LPG tubes to be brought back. To determine the route, one must consider the vehicle capacity and the ratio of the number of LPG tubes delivered and picked up. This research used a tabu search algorithm to get the proposed route. The steps in the tabu search algorithm includes  determination of the initial solution, the neighborhood search, intensification phase, diversification phase,  standard phase, and  interactive phase. By using the tabu search algorithm, the proposed route provided a savings of transportation costs of 13.72% rather than the initial route of the company.

Abstract

Hybrid flow shop scheduling is one topic that is often reviewed by researchers at this time. Hybrid flow shop scheduling is the development of problems from pure flow shop. Flow shop problems have one machine at each stage. In this problem, each stage of operation has a machine that is arranged in parallel. This article aims to discuss the issue of hybrid flow shop scheduling at three stage to minimize makespan. Some previous studies discussed scheduling problems by considering setup time. However, such research is generally for the problem of pure flow shop. Therefore, a new algorithm is proposed to solve the problem. The proposed algorithm is developed from the Pour heuristic algorithm. Several experiments were conducted to determine the performance of the proposed algorithm. This study uses ten numerical experiments. This experiment uses the number of jobs varying from 5 jobs to 50 jobs. The results of numerical experiments show that the proposed algorithm has better performance compared to some other algorithms. The proposed method produces an effective solution if it is used to solve problems with a large number of jobs..

Abstract

Production scheduling is an important activity in manufacturing. Optimal scheduling affects the time of completion of the work. PT. Interpack is a company that produces packaging machines. The job schedule of the product spare part still uses the random priority rules. Use of random rules makes a lot of time delay. Delay causes operator and machine idle. Delay also causes the total time of completion of the work (makespan) and delay the greater.  So it needs to be rescheduled to work on the spare part of product. Job scheduling using the Artificial Immune System (AIS) algorithm. AIS was developed by Farmer et al. The AIS algorithm refers to the human immune system. The stages of the AIS algorithm begin with random initialization, antibody representation and gene classification, clone breeding, selection of donor antibodies, germ-line construction, gene fragment redesign, and ending with diversification of antibodies. AIS algorithm scheduling resulted in a more optimal new schedule. AIS algorithm scheduling generates a future of 6483.91 minutes. Company scheduling generates makespan of 7059.99 minutes. AIS Schedule finishes algorithm 4 days of the due date. AIS algorithm schedule increase machine utility by 1%.
