Abstract

Scheduling lecture is scheduled number of components consisting of courses, lecturer, students, classrooms, and time with a number of restrictions and requirements (constraints) certain to get optimal results and the best. In this paper will be discussed and created scheduling lecture with a problem-solving approach to the science of Artificial Intelligence (Artificial Intelligence), by using an approximation of the mathematical problem that is aiming to find a situation or object that meets a number of requirements or specific criteria (Constraint Satisfaction Problem) to get the optimal scheduling and the best. To solve these problems the solution search techniques used by an algorithm that will result in optimal scheduling and the best (heuristic search) techniques combined with Smart Backtracking and Look Ahead called Intelligent Search to find and resolve problems when encountered a condition where no there is a solution in due course scheduling constraints and requirements are not met (deadlock). The application of these methods and techniques in the course scheduling information system is built, using the PHP programming language and MySQL database to solve the problem of scheduling to get optimal results and the best.

Abstract

Pada dunia industri saat ini memerlukan suatu peralatan yang dapat bekerja secara otomatis, sehingga mampu meningkatkan waktu setup, dan mempersingkat waktu produksi. Tujuan dari penelitian ini untuk merancang sebuah peralatan yang mampu mendukung kegiatan produksi berjalan lebih baik kemudian dianalisis menggunakan metode SMED. Peralatan yang dimaksud adalah sebuah mesin press hidrolik dan meja rolling yang diharapkan dapat membantu proses kerja penggantian dies sehingga lebih mudah dan cepat. Permasalahan lainnya yang timbul karena proses penggantian dies yang lama adalah supply chain yang sering terlambat untuk perpindahan produk ke  lini produksi selanjutnya. Berdasarkan permasalahan tersebut, maka bidang fokus kedua pada penelitian ini adalah upaya minimalkan waktu yang diperlukan saat setup mesin ketika melakukan pergantian/ changeover komponen pada rancangan mesin press hidrolik dan meja rolling yang telah dibuat. Hasil yang diperoleh pada meja hidrolik yang telah dibuat sebelumnya di analisis menggunakan metode SMED untuk penggantian dies mendapatkan peningkatan laju pergantian dies sebesar 46 %. Hal ini mendapatkan kesimpulan bahwa dengan penggunaan meja hidrolik pada penggantian dies mesin press 110 Ton dapat meningkatkan laju produksi pada perusahaan tersebut sehingga kegiatan produksi meningkat lebih baik.

Abstract

Tools in the production process are needed in the production process in order to accelerate and improve the quality of production, especially in the automotive industry. In this study, a jig positioning machine design will be designed which is used when assembly on the roof panel of a car so that it can help areas that are difficult to reach when doing assembly or design on the roof panel of the car. After designing the required design for the car interior roof panel assembly, it is necessary to test the design of the machine so that when the material on the machine ready to be made is already in the safe category. Testing on the machine is carried out using a material with the type of Aluminum Alloy 6035-t5 with the addition of different force factors, namely 34.3N, 39.2N, and 44.1N. The addition of the force factor is based on the maximum load given when doing the roof panel assembly on the car. The test is carried out by performing simulations using CAD Software on the arm of the jig positioning machine which will be the support when applying the load. The simulation carried out will analyze the value of material suitability factors including the value of deformation, strain-stress, and factor of safety on the jig positioning machine. The results of the simulation show that there is a change in the value of the material suitability factor due to the difference in the applied force. The suitability factor of the material on the designed jig positioning arm can accommodate the weight of the load with a maximum force of 44.1N with a maximum displacement value of 1.062e+02 mm, a stress value of 1.087e+08N/m^2, a FOS value of 1.33e+00, and a Strain value of 1 ,19e-03. Based on the simulation results of the suitability factor of the material, the jig positioning arm is within safe limits.

Abstract

A series of predictable preventive activities to overcome machine failure during operation is very important because it produces good and stable spare parts. This research was carried out with the aim of preventing machine damage due to short circuits that occur in injection molding machines used for the sudden production of automotive component spare parts. The research was carried out using the Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR) approaches to calculate the time between the machine breaking down and the time it was repaired. The MTBF calculation results in this research were 72.9 hours or less than 4 days the engine would experience damage or every 72.9 hours the engine would experience damage again. The MTTR value obtained is 2 hours, where in 2 hours the work to overcome the damage can be done.
