The focus is to reduce the cost in slickline and electric line operation in order to maintain the business continuity, where this conclusion was obtained by looking at the comparison between the costs incurred during previous operations with the costs incurred at this time by comparing the results of operations obtained as well as comparisons with oil and gas prices both before and after 2018. This concrete step to be taken is a method for lean management because there is a cost suppression in it. The context of its implementation is through Business Process Re-engineering which of course will implement appropriate method steps to be taken. The method steps taken are to implement Value Stream Mapping which in its preparation includes an analysis of the slickline and electric line operation work steps carried out, including by compiling; Product family or operation work steps, Current state map of both operations and Design future state map of Wire Line operation proposal and 5S theory process as completeness. The proposed strategy enable to reduce costs by combining slickline and electric line operations in one unit or one service company, then reducing the number of workers involved and making work more efficient, by reducing the Rig up and Rig process, Down PCE (Pressure Control Equipment), reducing the repetition of the work intervention process.</p> Rendi Harun Putra, Winda Nur Cahyo, Tieling Zhang Copyright (c) 2022 Rendi Harun Putra, Winda Nur Cahyo, Tieling Zhang https://creativecommons.org/licenses/by-sa/4.0/ http://journal3.uad.ac.id/index.php/spektrum/article/view/22 Wed, 20 Apr 2022 00:00:00 +0000 Application of The DMAIC Method in Improving The Quality of Electric Power Steering Housing Products http://journal3.uad.ac.id/index.php/spektrum/article/view/16 <p>PT. ABC is a manufacturing company that produces Electric Power Steering (EPS) Housing components. For the past three months, there have been problems with the EPS production process. The problem is related to the finding of defective products which on average reached 3.9% of the total production, and has exceeded the maximum limit allowed by the company, which is 2%. This study aims to overcome these problems by making improvements using the DMAIC method in the hope of finding the root cause of the emergence of defects and making improvements to reduce the number of defects that occur. The improvement results have shown that the number of defects reduced from 3086 pcs to 1948 pcs per 22 working days or decreased by 0.54% with an increase in sigma level from 3.95 to 4.01 sigma. In this case, DMAIC implementation is effectively reduced defects by 1.5% based on the sigma level. To achieve a 6-sigma level equivalent to a world-class industry, companies must make continuous improvements by fixing other root causes.</p> Hery Hamdi Azwir, Zaenal Fanani, Hirawati Oemar Copyright (c) 2022 Hery Hamdi Azwir, Zaenal Fanani, Hirawati Oemar https://creativecommons.org/licenses/by-sa/4.0/ http://journal3.uad.ac.id/index.php/spektrum/article/view/16 Wed, 20 Apr 2022 00:00:00 +0000 Aggregate Planning Implementation for Planning and Controlling The Materials in The Beverage Packaging Industry http://journal3.uad.ac.id/index.php/spektrum/article/view/25 <p>The Beverage Packaging Industry is a company that produce ready-to-drink drinks that produces Box Bottle Tea (BBT) 250 slim products. This product is sent to several customers and distributors throughout Indonesia. During 2020 the demand for this product has increased. In addition, the increasing demand also fluctuated significantly so the company was unable to predict production schedule. The continuity of the production process to meet consumer demand requires good production planning. The purpose of this research is to plan and control the production process of BBT 250 slim to obtain optimal raw material requirements. This study uses the method of Linear Regression and Aggregate Planning. Based on the analysis with Linear Regression, this study resulted in a model Y=319.575+3.723X, meaning that if demand decreases, the amount of production also decreases. This model is very useful for the Beverage Packaging Industry in planning and controlling raw materials for production. Calculation of raw material requirements for BBT 250 slim products results in an efficiency of raw materials than usual forecasting.</p> Indra Setiawan, Nurdiansyah Nurdiansyah, Muh.

This indicates the high necessity for a secure and reliable system, such as the Wireless Sensor Network (WSN), which provides auspicious and flexible solutions for the industry. It is one of the most excellent and trendy solutions to the crisis existing within the oil and gas industry, especially in the midstream pipeline. In this application, the nodes were arranged in a linear architecture, to cover a long distance of the pipe. The factors causing the degradation of the overall network performance with increasing density were also identified, due to the increment of the load causing clogging and inhabiting the packet queue. This subsequently led to packet loss, throughput unfairness, higher power consumption, and passive nodes’ presence in the network. The proposed routing protocol (AODVEO) was also reactive based on the AODV reducing the instabilities by splitting the traffic into even and odd paths. Additionally, the performances of AODV and DSDV were used to benchmark the efficacy of the proposed routing protocol.</p> M. Y. Lee, A. S. Azman, Siva Kumar Subramaniam, F. S.

This program allows student to study in different university and majors. It was attended by students of Engineering Faculty from UNIX in State and Private University throughout Indonesia. By participating PMM, the student have overload credits because they have to finish double credit from homebased and destination university. This condition affects the burden on students both physically and mentally. This mental burden of students has an impact on student achievement academically, so the mental burden analysis is needed. In this study, an evaluation of the mental workload was carried out using the NASA-TLX approach. The result found that in general 75% of students experienced a very high workload. The percentage of students who take PMM in State University as much as 50% is in the category of high mental workload and 50% is very high category. The percentage of students who take PMM in Private University is 25% in the very high category and 75% is in the high category. From this study, UNIX can have some consideration about providing the brief (tips and tricks) before PMM for student mental preparation and choosing the Private University for destination university.</p> Wildanul Isnaini, Halwa Annisa Khoiri, Putri Cahyaningtyas Copyright (c) 2022 Wildanul Isnaini, Halwa Annisa Khoiri, Putri Cahyaningtyas https://creativecommons.org/licenses/by-sa/4.0/ http://journal3.uad.ac.id/index.php/spektrum/article/view/28 Wed, 20 Apr 2022 00:00:00 +0000 Design of Working Table for Fret Wiring Operators With Nida Method in Guitar Industry Mancasan Sukoharjo http://journal3.uad.ac.id/index.php/spektrum/article/view/15 <p>The guitar industry is in Mancasan, Sukoharjo regency is a small<br />medium enterprises which carried out finishing process to produce<br />acoustic guitars. All of the process are done manually without any<br />machine. There is one process called fret wire installation where the<br />operator is in a static work posture for an extended period of time to<br />hold the work piece. Nordic Body Map (NBM) assessment showed<br />that almost all assessed workers have pain in hip and right upper<br />arm. There is indication of Musculoskeletal Disorders (MSDS) risk in<br />left upper arm, back, and waist of workers who conduct fret wires<br />installation process. This indication is confirmed using REBA. REBA<br />Score for fret wiring operator is 10, it indicates that the investigation<br />and modification was needed as soon as possible. This arises to a<br />problem called workers MSDS due to awkward posture. This<br />research aims to design an ergonomic working table to reduce the<br />risk of musculoskeletal disorder for fret wire installation operators.<br />REBA was used to evaluate working posture to find the specific<br />problem. In addition, NIDA product development process and<br />anthropometry concept were also implemented to develop working<br />table based on the problem previously found. The result is the<br />proposed working table which specifications are has adjustable<br />system on the leg of the table, features a lock to hold the guitar<br />head, a support with a pad for the neck and body of the guitar, a<br />work tool area and a half-coil fret wire arrangement, and a curved<br />table base so that the operator is in a comfortable position and is<br />close to the work piece.</p> Rahmaniyah Dwi Astuti, Fathin Kusumo Pramesti Pudjiantoro, Bambang Suhardi, Irwan Iftadi, Annisa Syahiliantina Copyright (c) 2022 Rahmaniyah Dwi Astuti, Fathin Kusumo Pramesti Pudjiantoro, Bambang Suhardi, Irwan Iftadi, Annisa Syahiliantina https://creativecommons.org/licenses/by-sa/4.0/ http://journal3.uad.ac.id/index.php/spektrum/article/view/15 Wed, 20 Apr 2022 00:00:00 +0000 Ergonomic Risk and Musculoskeletal Disorders in Rice Farmers at Karang Tanjung Village, Karawang Regency http://journal3.uad.ac.id/index.php/spektrum/article/view/34 <p>This study discussed musculoskeletal risk analysis related to ergonomics, occupational safety, and health in agriculture in the Karawang district. Musculoskeletal Disorders (MSDs) are occupational diseases that cause pain in the joints. The working position of rice farmers, especially during planting rice seeds and harvesting rice, is not suitable for ergonomics. This study aims to identify the MSDs experienced by farmers in Karang Tanjung village, Karawang district. The study used an analytical method using the Nordic Body Map (NBM) and RULA questionnaires to assess work posture. A sample of 30 workers was chosen for an observational cross-sectional study. The results showed that the ergonomic risk level entered level 4 in the high category. The most dominant MSDs felt by rice farmers in Karang Tanjung village were the waist (98%) and the neck (95%). This research was expected to serve as a model for future musculoskeletal risk reduction research.</p> Nana Rahdiana, Sani Suhardiman, Sukarman Sukarman Copyright (c) 2022 Nana Rahdiana, Sani Suhardiman, Sukarman Sukarman https://creativecommons.org/licenses/by-sa/4.0/ http://journal3.uad.ac.id/index.php/spektrum/article/view/34 Wed, 20 Apr 2022 00:00:00 +0000
