Abstract
In a manufacturing company, the machine is one of the most important elements in their production process because machine failure can stop the production process. Therefore, the initial step to minimizing losses caused by machine failure can be done by evaluating the machine condition. Evaluation of machine performance is carried out by measuring the effectiveness of the machine with the Overall Equipment Effectiveness (OEE) method. Based on the calculation result, the OEE value of the machine is 68.63% and this value still under the Japanese Institute of Plant Maintenance standard. Six big losses analysis is performed to determine the biggest loss that affects the effectiveness of the machine. The result of six big losses calculation shows that the most influential factor for the low OEE value of the machine is Reduced Speed Loss (39.12%). Causal analysis with a fishbone diagram is done to find out the causes of the highly reduced speed loss. To calculate the equipment cost loss use the Overall Equipment Cost Loss (OECL) methods. The total of the overall equipment cost loss is IDR 849, 839, 947.53.

Using the Bees Algorithm to solve combinatorial optimisation problems for TSPLIB
Authors: Ismail A H , Hartono N , Zeybek S , Pham D T 
Published: May 2020

Abstract
The Bees Algorithm (BA) is a metaheuristic algorithm to find good solutions to optimisation problems in reasonable computing times. This paper is the first to report on the use of the BA to solve 9 combinatorial optimisation problems (COP) with more than 100 cities from TSPLIB rigorously to test the performance of the algorithm. The work employed a basic version of the BA for COP and TSPLIB datasets involving between 100 and 200 cities. The results obtained show that deviations from the best-found tour lengths for the datasets with 100 cities and 200 cities were approximately 2.5% and 7.5%. The reason for this jump in deviations was that the number of iterations was kept constant for all experiments while the solution space increased factorially with the number of cities. This research can be replicated and modified through Google Colab.
Performance Evaluation of an EWMA p Chart Based on Improved Square Root Transformation to detect Small Shift Process Variation
Authors: Arumsari  , Rifqi J N 
Published: May 2020

Abstract
A control chart was used to detect whether the unexpected variation due to special causes was happening. Generally, Shewhart control chart was used, while this chart was not a good one to control the process with small variation. EWMA p chart was one of the alternatives used to monitor small shifts in the process mean. Traditionally, attribute Shewhart p chart has been developed for charting the binomial data or using the normal approximation when percent defective was low and sample size was small. In 100% inspection, these assumptions were not valid. For this reason, EWMA p control chart was modified by improving square root transformation. In this research, the implementation of the modified EWMA p control chart based on Improved square root transformation (ISRT p EWMA chart) was studied. This chart was used to monitor the actual production process where the process has shifted. The research found that. The ISRT p EWMA chart detects the shift twice, while Shewhart p chart does not detect any shift. The research also found that at λ = 0.25, the shift is detected 2 times, at λ = 0.5, the shift is detected once while at λ = 0.75, no shift is detected. The larger the value of the λ parameter, the worse the ISRT p EWMA control chart performed.

Abstract
Lean manufacturing tools have been applied for several years to improve company’s internal logistic. Furthermore, a lot of factors such as globalization, competition and shorter life-cycle product force companies to create production process more efficient and cheaper. The acceptance of lean philosophy in the company means not only respecting the lean principles in the manufacturing area, but also in all the process that performed inside the company. The implementation of lean principles in the warehouse area is a certain step of improvement warehouse process and performance, but also the whole company. However, the implementation of lean principles in warehouse area is relatively new subject in logistics. Most of the research that has been done before only focused on eliminate waste and didn’t count the cost that can be saved after lean implementation. This paper’s objective is to identify waste that might be able to appear in warehousing process using value stream mapping. After the waste successfully identified, the next step is doing improvement using lean tool and count the implementation cost using linear programming. The result of this paper is choose which tool that make lower implementation cost and higher time reduction

Authors: Iqbal M , Suzianti A 
Published: May 2020

Abstract
New Product Development (NPD) is important for the growth and sustainability of companies. One of the most important factors in NPD is the management of the NPD process. NPD process is believed to be a crucial factor in NPD success. NPD process may vary between organizations. Companies must be able to implement the most suitable NPD process. Therefore, the design of NPD process is crucial. This article proposes a tool that can support organizations to design their NPD process. The tool is conceptualized based on the sequence of NPD design method. The tool is based on the form of ‘space of elements’ and called the NPD Process Design Canvas. The concept has been tested and several feedbacks identified. Some of the pros are its ability to capture the risks and elements of process design. Some of the cons are the variation of detail and inability to describe the existing process. Based on the feedbacks, improvements proposed are the addition of specific ‘iterations’ and ‘reviews’ analysis in the canvas, and the paradigm of the canvas as the integrator of several analyses carried out based on the sequence of NPD design method. Further research may focus on the testing of a more sophisticated canvas implementation and how the tool considers the position of companies’ existing NPD process.

Abstract
Tyres are a very important component of a motorcycle. Not only vehicle driving components, tyres also play a role in safety, passenger comfort, fuel consumption efficiency, endurance components of car legs and so forth. So, the condition of the tyre must receive special attention from the owner of a motorized vehicle. When riding on a motorcycle, tyre leakage is one of the problems that is often encountered. Not only because of sharp objects, tyres can also leak due to several other reasons. If problems are not immediately sought, leaks in tyres can cause loss of control, endangering the safety of motorists and other road users. And the place and timing of leakage events that cannot be predicted are often a scourge for motorists. After a leak, motorists, especially motorcycle riders, are very dependent on the existence of patched tyre entrepreneurs. With helps from IoT application based in advance, the design of this tool will be an opportunity for tyre patch entrepreneurs to be able to “Pick Up the Ball” to every customer / driver who has a leak. The design of this tool is quite concise and integrated thru Programmable Logic Control (PLC) with each main component making easier for entrepreneurs for patching tyres and can reduce downtime repair / replacement of the tyre.
