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.

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.

Proper timeliness is vital for a lot of real-world computing systems. Understanding the phenomena of extreme workloads is essential because unhandled, extreme workloads could cause violation of timeliness requirements, service degradation, and even downtime. Extremity can have multiple roots: (1) service requests can naturally produce extreme workloads; (2) bursts could randomly occur on a probabilistic basis in case of a mixed workload in multiservice systems; (3) workload spikes typically happen in deadline bound tasks.Extreme Value Analysis (EVA) is a statistical method for modeling the extremely deviant values corresponding to the largest values. The foundation mathematics of EVA, the Extreme Value Theorem, requires the dataset to be independent and identically distributed. However, this is not generally true in practice because, usually, real-life processes are a mixture of sources with identifiable patterns. For example, seasonality and periodic fluctuations are regularly occurring patterns. Deadlines can be purely periodic, e.g., monthly tax submissions, or time variable, e.g., university homework submission with variable semester time schedules.We propose to preprocess the data using time series decomposition to separate the stochastic process causing extreme values. Moreover, we focus on the case where the root cause of the extreme values is the same mechanism: a deadline. We exploit known deadlines using dynamic time warp to search for the recurring similar workload peak patterns varying in time and amplitude.

 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%.
