PT. Selamat Sempurna, Tbk is a company that manufactures  automotive parts, namely car filters. This filter product has many part numbers. In this company has one of the production lines, namely Line Seat Press Shop, this line produces components from filters, namely seat components. Seat is the main part of the filter component that functions as a filter holder to the engine. This Seat component consists of several part numbers (shapes or variations) following the filter product, and some part numbers handled by the manual engine B070 & L224 will affect the changes in the production engine settings. This production machine includes machines that require time in a slow setup process for switching dies when switching from one part number to another part number compared to other machines, because the element of the process setting is long. With a fishbone diagram, the root cause of the Change Over Part long problem on the machine is from the method category (there is no preparation desk dies and there is not separation of external setup and internal setup). Previously the time needed for Change Over Part was 1961 seconds. After knowing the root cause of the problem and the improvement of the time needed is only 866 seconds. The time difference is 1067 seconds, so save on average time 1095 seconds or 18 minutes / setup. Keywords: Filter product, Change Over part (COP), Fishbone Diagram, Setup, Process Elements.

PT Pertamina EP Field Sangasanga is committed to completing the work program that is launched every year. It is expected to support the 2020 production target of 5380 BOPD as written in the 2020 Work Program. One of the efforts to increase the production rate of Field Sangasanga is to do Well Service Maintenance (WSM). Data of different failures during performing WSM work are collected. The frequency of breakdowns and size of loss were identified and analyzed employing quality improvement tools are; Pareto and Fishbone Diagram. Results indicate that tubing leaks cause 51.6% of the potential loss. Tubing often leaks because the wall thickness is less than the minimum. Root-cause-analysis highlights that most failure in the tubing is caused by the existing inspection tool cannot check the entire thickness of the tubing surface. Leaky tubing leads to many problems, such as increased work time, operational costs, and loss of production. We developed an inspection robot named Thicktube, which uses simple Arduino programming, equipped with a VL53L0X proximity sensor for measurement, SMS feature, and micro-SD feature. The Thicktube is fitted with a motor speed of 0.36 m/s driven by a battery remote control. With three sensor angles, Thicktube is designed to measure the thickness of the tubing as much as 27 points on one joint dimension along 9 meters. The test to compare the result is measured using Thicktube and Ultrasonic Thickness. Thicktube has a measurement accuracy of 82% with a measurement resolution of 1 mm. Thicktube as a preliminary tubing inspection can reduce the incidence of downtime due to leaky tubing. By applying Thicktube tools, a company can save up to Rp. 3.1 billion. In addition, the potential hazards of pulling out the tubing can be avoided.

Remanufacturing has gained attention from industry, but the literature lacks the scientific comprehension to realize efficient remanufacturing. This hinders a company from commencing or improving remanufacturing efficiently. To fill this gap, the paper proposes a set of practical success factors for remanufacturing. To do so, it analyzes remanufacturing practices in industry through interviews with staff from remanufacturing companies with long experience. The practical success factors are found to be (1) addressing product and component value, (2) having a customer-oriented operation, (3) having an efficient core acquisition, (4) obtaining the correct information, and (5) having the right staff competence. Next, the paper further analyzes remanufacturing processes theoretically with both cause and effect analysis and means-ends analysis. Since the factors show that, among other things, the product/service system (PSS) is highly relevant to remanufacturing in multiple ways, theories on the PSS are partly utilized. As a result, the distinctive nature of remanufacturing underlying in the processes is found to have high variability, high uncertainty and, thus, also complexity. The obtained insights from practice and theory are found to support each other. In addition, a fishbone diagram for remanufacturing is proposed based on the analysis, including seven m's, adding two new m's (marketing and maintenance) on top of the traditional five m's (measurement, material, human, method, and machine) in order to improve customer value. The major contribution of the paper lies in its insights, which are grounded in both theory and practice.

Root cause analysis techniques are an excellent choice for identifying the root causes of cost deviation in Iraqi construction projects. Many root cause analysis tools, such as the Fishbone diagram (FD), Pareto diagram (PD), and 5-Why analysis, have started to emerge from the literature as standard guidelines for identifying root causes. This study identified eighteen causes of cost deviation in construction projects, which they classified into three major groups (planning causes, designing causes, and execution causes). Pareto study indicates that twelve causes out of eighteen represent the most significant causes of cost deviation. After that, these eleven causes were filtered by 5-Why analysis, which concluded that insufficient project information and the implementation method is not appropriate with the project type are root causes for the planning group, while unclear owner requirements and changes in design are root causes for the designing causes group, Finally, changes in orders is a root cause for execution group.

The Mining Industry is one of the pillars of national economic development. In this industry, heavy equipment plays an important role in the coal mining process in Indonesia. By using heavy equipment must be well structured, so that the project can run easily without any obstacles. This research aimed to evaluate the cause of the low-value OEE of the Excavator Hitachi EX2500-6 of EX157 and EX158 units and determine the way to repair so that the equipment performance can be improved. This research uses descriptive quantitative approach with value analysis methods Overall Equipment Effectiveness (OEE). The result of OEE values were analyzed using losses classification method so that the occurrence of loss factors can be found and root cause analysis performance using a causal diagram/fishbone diagram and then make any improvement recommendations that can be done by using 5W1H analysis. Based on the research results, the OEE values of two excavators were calculated and were compared with the benchmark values. The values of OEE were found to be 84% for EX157 units and 68% for EX158 units. The low value of OEE on EX158 caused by unscheduled maintenance time losses amounting to 1188.3 hours. The high of time loss is influenced by trouble on Machine Frame, Structure, Body, and Cab components amounted to 60.9%. The root causes of the losses derived from the availability of external mechanics, the competence of mechanics, the availability of spare parts, and the implementation of condition monitoring was not optimal. While remedial steps can be taken by giving technical training program for mechanics as maintenance practice methodology.

 ABSTRAKDischarge planning merupakan suatu proses yang kompleks yang bertujuan untuk menyiapkan pasien dalam masa transisi di rumah sakit sampai pasien tersebut kembali ke rumahnya, dimana pelaksanannya harus dibuat sejak awal pasien datang ke pelayanan kesehatan. Pelaksanaan discharge planning  di rumah sakit dilakukan sebelum pasien pulang, atau sebelum pasien keluar dari unit layanan Pengamatan yang dilakukan penulis terhadap pelaksanaan discharge planning di ruang ICU, perawat lebih mengutamakan memperhatikan kondisi kritis pasien, sehingga melupakan pelaksanaan discharge planning.  Tujuan tulisan ini adalah melakukan analisis terhadap pelaksanaan discharge planning  di ruang ICU RS X Jakarta. Metode yang digunakan adalah metode analisis dengan menggunakan fishbone dengan asesmen yang dilakukan berupa observasi, wawancara dan pengumpulan data sekunder yang sudah ada di RS X Jakarta, setelah itu dilakukan pencarian literatur untuk  mengidentifikasi akar masalahnya, sehingga bisa diusulkan rekomendasi untuk penyelesaian terhadap masalah tersebut. Dari hasil analisis ditemukan akar masalah yaitu pengetahuan perawat yang kurang tentang discharge planning dan  kurang optimalnya sistem yang mendukung pelaksanaan discharge planning seperti format, SPO dan panduan. Rekomendasi yang di usulkan yaitu berupa perbaikan format discharge planning, revisi SPO, pembuatan panduan dan pelaksanaan pelatihan discharge planning.ABSTRACTDischarge planning is a complex process that aims to prepare patients in the transition period in the hospital until the patient returns to his home, where the implementation must be made from the beginning the patient comes to the health service. However, discharge planning was done before the patient returns, or before the patient left the service unit in Hospital. In the ICU room with critical patient conditions, nurses prioritize paying attention to the critical condition of the patient, thus forgetting the implementation of this discharge planning. For this reason, this paper aimed to analyze the implementation of discharge planning in the ICU of Jakarta X Hospital, literature study to identify the root of the problem, so that recommendations can be proposed to resolve the problem. The method was used an analysis using fishbone diagram with an assessment conducted in the observation form. Interview and secondary data collection from Jakarta X Hospital. Based on the analysis results, the root cause of the problem is knowledge of nurses who are less about discharge planning and less optimal systems that support the implementation of discharge planning such as format, SPO and guidelines. For this reason, recommendations for improvements were made in the form of redesigning the format of discharge planning, revision of SPO, making guidelines and implementing discharge planning training

UKM Kerupuk Acoy is a small and medium business engaged in the production of kerupuk and kemplang which has been established since 2012. After conducting interviews it was found that there were internal problems caused by a decrease in productivity, namely the use of resources that were not yet efficient so that although there was an increase in sales but the benefits are not maximized. To overcome this, it is necessary to apply the APC method to see which inputs have an index below 100% so that improvements are needed to increase productivity. The results of data processing showed a decrease in productivity levels material, energy, and capital inputs. Using fishbone diagram analysis, the root cause of the problem was found, namely low material productivity due to waste of raw materials for flour and cooking oil as well as too dense kerupuk dough form and making kemplang dough rolls too large, low energy productivity due to gas waste due to infrequent cleaning of stove fires, and low productivity. capital because the amount of working capital used is not proportional to the output produced. The solutions to increase productivity that have been implemented are cleaning the stove fire after use, reducing working capital, reducing the size of the cracker print and the diameter of the kemplang rolls, and paying attention to the use of flour and cooking oil so as not to spill on the floor. After implementation, there was an increase in the productivity of material, energy, and capital inputs respectively by 6.28252%; 6.28278%; and 0.05713% which causes an increase in output productivity of 6.283%.

PT PLB (pseudonym) is a company that produces household appliances and kitchen utensils. The country kettle is one type of product made by PT PLB. The productivity of the country kettle production line decreased by 56%. This was due to defective products. The largest percentage of defects in-country kettle products occurred in the spinning process of 40.18%. This study aimed to identify the causes of defects in-country kettle products and how to overcome them by designing improvement proposals. Lean manufacturing principles were used to evaluate the problems that occur. There were three types of lean manufacturing tools used in this study: Value Stream Mapping (VSM) and 5Ways. VSM was used to describe and identify value-added activities, non-value-added activities but necessary, and non-value-added activities so that the production process becomes lean. The root cause analysis was performed using the 5 Whys method. Unskilled workers and non-standard material types between suppliers are the highest contributors to defects in the spinning process. Based on this, this research was focused on improvements made in the spinning process. Proposals for improvements to the causes of the problems found are standardization of work procedures, standardization of supplier specifications, and arrangement of semi-finished goods and/or supplies. Based on the company's results, the proposed standardization of work procedures and arrangement of semi-finished goods and/or supplies may be implemented in the company. Meanwhile, the proposal for selecting suppliers is not feasible due to company limitations
