The ANALISIS BEBAN KERJA OPERATOR PAPER MESIN #6 PT. INDAH KIAT PULP AND PAPER TBK MENGGUNAKAN METODE CARDIOVASCULAR LOAD (CVL) DAN SUBJECTIVE WORKLOAD ASSESSMENT TECHNIQUE ( SWAT )

Indah Kiat Pulp and Paper Tbk merupakan perusahaan industri manufaktur yang bergerak dibidang pengolahan bubur kertas, salah satu mesin kertas terbesar di Perawang adalah Paper mesin #6. Paper mesin #6 beroperasi secara kontinyu 24 jam dan untuk mendukung proses produksi tersebut jam kerja karyawan dibagi menjadi 3 shift kerja. Permasalahan yang terjadi pada paper mesin ini adalah tingginya angka kecelakaan kerja dikarenakan tingginya beban kerja yang dirasakan oleh operator sehingga menyebabkan operator kelelahan baik fisik maupun mental. Penelitian dilakukan pada operator stasiun produksi Wet End, Dry End, Chemical, Winder dan Thimons yaitu dilakukan pengukuran beban kerja fisik dengan menggunakan metode Cardiovascular Load (CVL) dan pengukuran beban kerja mental dengan metode Subjective Workload Assessment Technique (SWAT). Hasil perhitungan metode CVL bahwa beban kerja fisik yang paling besar pada shift 3 grup B terjadi pada operator Thimons 1 memiliki nilai % CVL sebesar 46,62 % dengan rekomendasi diperlukan perbaikan dan operator Wet End 3 dengan nilai % CVL sebesar 44,74 % dengan keterangan diperlukan perbaikan. Berdasarkan hasil CVL, sebanyak 12 karyawan mengalami beban kerja fisik. Berbeda dengan kepala shift dan operator Dekstop Control System (DCS), beban kerja yang dirasakan cenderung lebih ke beban mental. Penelitian pada kepala shift dan operator DCS menggunakan metode, metode SWAT digunakan untuk mengukur beban kerja mental. Penelitian dilakukan dengan cara pengamatan dan wawancara secara langsung, selanjutnya kepala shift dan operator DCS diminta untuk mengurutkan 27 lembar kartu SWAT yang terdiri dari Time Load(T), Mental Effort Load(E) dan Psycological Stress Load (S). hasil pengurutan kartu SWAT diolah dengan menggunakan aplikasi DosBox 0.74, setelah itu dilakukan pengkonversian nilai dari Time, Effort dan Stress (T.E.S). Berdasarkan perhitungan beban kerja mental kepala shift, faktor yang paling berpengaruh adalah faktor Time dengan nilai 60,44% diikuti faktor Effort dan Stress dengan nilai 29,64% dan 9,92%. Hal serupa dengan operator DCS, faktor yang paling berpengaruh adalah faktor Time dengan nilai 68,57% diikuti faktor Effort dan Stress dengan nilai 23,29% dan 8,13%. Beban waktu menjadi faktor utama yang dirasakan oleh karyawan karena tuntutan pekerjaan yang mengharuskan karyawan harus cepat dalam melakukan setiap aktivitas.

Selection of Underground Hydrogen Storage Risk Assessment Techniques

The article proposes the use of the analytic hierarchy process (AHP) method to select a risk assessment technique associated with underground hydrogen storage. The initial choosing and ranking of risk assessment techniques can be considered as a multi-criteria decision problem. The usage of a decision model based on six criteria is proposed. A ranking of methods for estimating the risks associated with underground hydrogen storage is presented. The obtained results show that the application of the AHP-based approach may be a useful tool for selecting the UHS risk assessment technique. The proposed method makes it possible to make an objective decision of the most satisfactory approach, from the point of view of all the adopted decision criteria, regarding the selection of the best risk assessment technique.

Risk Analysis and Assessment Using Decision Matrix Risk Assessment Technique in Sports: The Case of Boxing

Background: The decision matrix risk assessment (DMRA) is a systematic approach widely adopted in risk management in occupational health and safety to make a risk analysis and assessment and assist in decision-making for risk tolerability. Risk is a substantial part of sports organizations as well as other organizations and daily life; therefore, it is inevitable in any activity. One may encounter various risks of injury since sports fields and equipment are not ergonomic for performing sports activities healthily Aim: Ultimately, to help improve the conditions of sports activities, the present strummed to determine the activities to be maintained as a result of a risk assessment using the decision matrix risk assessment technique where accidents are classified by their severity and probabilities. Methods: The present study adopted DMRA (L-shaped matrix); it is among the systematic methods widely used in occupational health and safety (OHS) risk assessment. In general, it is an assessment technique where one may obtain a risk assessment value by considering two factors. Results: Likewise, we identified those requiring control measures and a cease at the last resort. Conclusion: Overall, we proposed some corrective actions that may help prevent the occurrence of the presented accidents through the implementation of occupational health and safety regulations published by the correspondent institutions. Keywords: Risk assessment, sports activity, health and safety, decision matrix, risk analysis

Application of the Delphi Technique to Determine the Technological Competencies of a Faculty Member

<p style="text-align: justify;">The formed primary level and dynamic and sustainable development of technological competence provides quality management of teaching activities, increases the efficiency of the educational process, accelerates the achievement of pedagogical goals. Delphi expert assessment technique is increasingly used in the paradigm of pedagogy. Due to the set of advantages and objectivity of assessments, it has become the dominant method of this study. The objective of the study is to determine the current level of manifestation of technological competencies, as well as generalized prospects for development and improvement of the identified level within the selected group of freelance teachers using the technology of independent expert assessments –the Delphi method. In general, the following methods were used in the current study: methods of data collection and coordination, anonymous brainstorming, Delphi expert assessment technique, statistical and mathematical processing of results through Delphi formulas, comparative method, generalisations. The diversified approach to the interpretation of the technological competence of faculty members allowed determining: a) the level of faculty members’ knowledge of modern educational technologies at 89.1%; b) activity-practical aspect of training at 83.0%; c) dissonance between the theoretical and empirical level of teacher training and the algorithm for fulfilling the potential in practice at 21.5%; d) mastery of individual creative technologies for the organisation of an effective educational process at 55.9%; e) forecasted development of technological competencies of faculty members in the 5-year perspective under the condition of application of special control and skill trainings at 50.7%. Conclusion of the study is that according to the arithmetic mean of experts’ assessments of differentiated levels of technological competence, the overall level was 75.1%. The average result of the initial student survey on the estimating of the teachers’ technological competence was 69.7%.

A Degradation Condition Assessment Technique Based on online_ISSE Degradation Feature and Logistic Regression Model

A degradation assessment technique based on an online improved symbol sequence entropy online_ISSE and a logistic regression model is proposed in this paper. Firstly, the threshold factor is introduced to retain the `coarse graining' information of direction changing and amplitude information, the `sensitivity' of improved symbol sequence entropy (SSE) to impact components is reduced and improved symbol sequence entropy (ISSE) is proposed. Then, a sliding window and Weibull distribution theory are used to effectively filter out the influence of fluctuations in the ISSE feature sequence, forming the degradation feature named online_ISSE. Finally, a logistic regression model is trained and constructed, and the health factor CV is calculated online to assess the degradation condition of the unknown signal samples. The lifetime vibration signal of the hoisting gearbox monitored from #8114 quay crane of the Shanghai Port Container Terminal is introduced for instance analysis. The results show that the proposed ISSE has a better effect in describing the complexity pattern than the SSE algorithm and that the degradation condition can be tracked and assessed accurately based on the technique proposed.
