Abstract

In the face of competition in the field of Education, universities are required to improve the quality of the learning process. The aspects included in the learning process are practicum activities. In the Industrial Engineering study program, there are several core practicums, one of which is the Integrated Industrial Engineering Practicum. This study aims to determine the quality of current PTIT practicum activities by measuring the level of satisfaction of students who take PTIT courses. The method used in measuring student satisfaction in this paper is the Service quality method (SERVQUAL). The SERVQUAL method is a method that pays attention to 5 dimensions of service quality, namely reliability, responsiveness, assurance, empathy, and tangible. This measurement is carried out to identify student expectations and perceptions from the five dimensions of Service Quality by looking at the gap value that occurs due to the mismatch between student expectations and perceptions. The data processed in this study was questionnaire data from 30 respondents. Before the analysis was carried out, data testing was carried out with validity and reality tests. The results of this study are dimensions that are not in accordance with student expectations, including tangible, assurance, and empathy dimensions, and those that are in accordance with student expectations are dimensions of reliability and responsiveness. Keywords: Practice, SERVQUAL, Students Satisfaction

Abstract

Kelancaran proses produksi selalu menjadi pengaruh besar dalam suatu industri untuk mendapatkan keuntungan maksimal dan mengefisiensikan waktu. Terjadinya bottleneck (Penyumbatan) pada lini produksi dapat menyebabkan delay dan idle time yang mengakibatkan proses produksi tidak maksimal secara kuantitatif maupun kualitas. Penerapan konsep penyeimbangan lini dapat memberikan keuntungan seperti keseimbangan tugas dan mengefesiensikan waktu produksi dan meminimalisasi waktu menganggur (idle time). Hal tersebut belum diterapkan pada PT.XYZ, dan belum diketahui apakah kegiatan produksi tersebut lancar maupun efisien. Dilakukan pendekatan dengan studi literatur dan lapangan dalam pengumpulan data dan melakukan pengolahan data dengan metode Rangked Position Weight (RPW). Dari pengolahan tersebut didapatkan hasil sebelum penggunaan RPW sebanyak 14 operasi dan 6 stasiun kerja, namun setelah menggunakan metode RPW meningkat sebesar 83,61%, balance delay menurun sebesar 16,40%. smoothing index menurun menjadi 1004,05%, dan stasiun kerja setelah menggunakan RPW menjadi 4 stasiun kerja dengan nilai efisiensi lebih tinggi. Dengan penerapan RPW dalam konsep line balancing dapat mengoptimalkan dan mengefisienkan lini produksi pada SB12 SPR PLT bagi PT.XYZ.

Abstract

A warehouse is a place used to store finished goods or raw materials and is an important factor so that the production process runs optimally, therefore a company needs adequate facilities and infrastructure. PT. SSD Lamongan experiences limited storage space for raw materials in the form of krosok salt. This company wants to purchase raw materials in large quantities to avoid large increases in raw material prices in the dry, wet, and rainy seasons. However, the current warehouse capacity is insufficient to store these raw materials. So the company plans to build a new warehouse to store raw materials. The construction of this warehouse requires careful consideration and calculations so that it is profitable in the future. Therefore, the aim of this research is to analyze the feasibility of investment by considering market and financial aspects for 10 years, using the Net Present Value (NPV), Internal Rate of Return (IRR), and Payback Period (PP) methods. Based on the results and calculations carried out by researchers, the Net Present Value (NPV) value obtained with an interest rate of 9.08% was IDR 4,615,037,364.00. The Internal Rate of Return (IRR) is 64.94% (IRR>9.08%) and the investment payback period (PP) will be returned for 1 year and 6 months. From the results obtained, this project is feasible.

Abstract

Manufacturing company PT. Varia Usaha Beton provides concrete products. On the concrete production line in Gresik, the company makes various types of concrete, one of which is precast concrete. In manufacturing activities, there are problems when carrying out production where there are orders whose production has not been fully realized. Aspects of workload can influence production demand which cannot be realized in its entirety because workers expend too much energy resulting in workers not being optimal and the limited number of workers resulting in demand not being met. To address this problem, researchers conducted a workload analysis on precast concrete production activities for each product and determined the number of workers needed according to production demand. The method used is using working time measurements and the Full Time Equivalent method to analyze workload and determine the number of workers according to the FTE value index. The results obtained after data processing and data calculations were carried out for operators working to produce precast concrete, 13 of which were overloaded and 2 of which were normal. After calculating the need for workers, the workers needed to meet the demand for precast concrete production requires 52 workers from the initial 24 workers.

Abstract

BI is a company that operates in the plastic packaging manufacturing industry. The main problem faced by PT. BI lies in the productivity and efficiency of the I-12 machine. The operational disruptions that occurred were a large number of breakdowns and less than optimal production levels so this machine did not reach the desired maximum capacity. The impact of these conditions can be detrimental to the company with the potential to reduce machine productivity and efficiency, as well as the possibility of incurring high costs. This research aims to evaluate the effectiveness of the I-12 engine by applying the Overall Equipment Effectiveness (OEE) method. According to the calculated data, the average Overall Equipment Effectiveness value from January to June 2022 is 81.32%, which means it does not meet the standards set by the Japan Institute of Plant Maintenance. Reduce speed losses on the I-12 engine have the largest percentage of the six big loss factors, namely 68.37%, which is the main cause of the decline in the effectiveness of the engine. Therefore, an in-depth analysis using a fishbone diagram is needed to find out the root cause of the problem. Keywords: Efficiency, Effectiveness, Overall Equipment Effectiveness, Six Big Losses
