Abstract
The Tea packaging paper sack process at PT. Perkebunan Nusantara VIII is done manually using human labor to lift paper sack weighing 40-60 kg. This condition makes it harder for the labor and increases the risk of Musculoskeletal Disorders (MSDs). In the existing condition, the RULA score is seven which have high risk of work accidents. To minimize the risk of MSDs, a proposed work tool is designed using the Ergonomic Function Deployment approach to produce ergonomic tools. The proposed work tool was developed with the ESHCE principle (Effective, Safe, Healthy, Comfortable, and Efficient) which became a variable in meeting the Ergonomic Function Deployment (EFD) approach. The research results showed that the proposed work tools could help workers in carrying out packaging activities with the decrease in the RULA value on the labor’s posture and could reduce processing time because it united all activities in the packaging area. So it can be concluded that the proposed work tools can reduce the risk of MSDs and can help workers to process the packaging of tea with minimum time.

Abstract
PT. Avesta Continental Pack is a manufacturer of flexible packaging for pharmaceutical products. The company faces ineffective production scheduling and repeatedly failed to finish orders at the expected time limit. Customers requesting orders in different finishing time contributes in causing delays in the delivery process. Consequently, customers ended up claiming the fee because of the late delivery. Therefore, a more advanced scheduling system will assist the company in managing the delivery time. The purpose of this research is to establish the most effective job scheduling arrangement to minimize mean tardiness as well as mean lateness job. As the production process uses flow shop method, this research applies heuristic methods, such as Earliest Due Date (EDD) method, Short Processing Time (SPT), Nawaz, Enscore, and Ham (NEH) algorithm and Campbell, Dudek, and Smith (CDS) algorithm. The result shows that SPT method provides the most optimum outcome, specifically by reducing mean tardiness by 801.81 minutes or 85.57% and decreasing mean lateness job by 2 or 66.67%. The best job sequence is subsequently job 8 - job 4 - job 1 - job 6 - job 7 - job 5 - job 2 - job 3, which minimizes the average delay time from 937.05 minutes to 135.24 minutes.

Abstract
Every company who performs production activities needs inventory of raw materials. The most important thing which is mandatory for all companies when performing their production activities is management of inventory, as inventory is an asset for a company. Availability of raw materials in the industry is expected to facilitate production/service activities to meet consumer needs. Ready-made garment industry, XYZ Pty Ltd is a family business established in 2004 located in Jakarta which engages in textile manufacture and has shown a relatively high demand. While XYZ Pty Ltd attempted to meet the demand, the inventory level was not able to balance with it, resulting in after-hour work of employees. In order to provide appropriate solutions, we proposed some strategies using Mamdani method and TFN (Triangular Fuzzy Number) range which selected appropriate rules to optimize inventory level of the company. Average of range score Fuzzy Interference System obtained for both production level and demand level were 36,500, while average of range score Fuzzy Interference System obtained for Inventory Cost and Inventory Level were 2,250,000,000 and 13,900, respectively. Rules resulting in a high inventory level are very good for use either together with other levels or not. Rules resulting in an intermediate inventory level are also good for use, in particular together with low and intermediate demand levels. Rules resulting in a high demand level are still good for use. On the other hand, rules resulting in a low inventory level are not good for use.

Published: June 2019

Abstract
PT. Carnegie Universal Industries manufactures holster products and magazine carrier. Holsters have the most variants and the highest demand. To produce a holster, a mold is needed for each type of handgun. A mold uses wooden mold and blue gun. Mold making takes the longest time compared to other stages in the holster production process. The mold making process does not yet have standards, therefore it takes a long time and high cost. The purpose of this study is to develop a process planning to facilitate the making of molds with automated systems using the Computer Aided Process Planning (CAPP) method, speed up production time, and reduce production costs. The CAPP generative approach is generated through decision logic, formulation, search, algorithm and geometric based data. Database programs are created to store detailed information on each print that has been created. This approach design proved that the mold making procedures are simplified and speeded up and have standards, so that the time and costs are used more effectively and efficiently.

Published: June 2019

Abstract
The hybrid assembly differentiation flow shop is a three-stage flow shop system with machining, assembly and differentiation stages. The machining stage produces k parts in independently unrelated dedicated machines. After k parts of a job completed, they are assembled at the assembly stage and assigned to dedicated machines for a final process. At the end, several types of finished products are resulted. The finished products should be delivered at their respective different due dates. The problem is to find a schedule considering multi due dates, and the criterion of minimizing total actual flow time. This paper proposes a model for job scheduling in a hybrid assembly differentiation flow shops and its algorithm for solving the problems. The initial solution is defined using SPT-based heuristic and it is optimized using variable neighbourhood descend method. The proposed model is tested using a set of hypothetic data. The solution shows that the algorithm can solve the problems effectively.
