Penelitian ini mengidentifikasi beban kerja mental operator SPBU XYZ dengan menggunakan kuesioner National Aeronautic and Space Administration–Task Load Index (NASA-TLX) dan perhitungan tingkat kelelahan kerja untuk menganalisis tingginya beban kerja mental pada operator SPBU. Perhitungan tingkat kelelahan kerja menggunakan metode Subjective Self Rating Test (SSRT) dari kuesioner Industrial Fatigue Research Committee (IFRC). Upaya yang dilakukan untuk menurunkan tingkat beban kerja mental operator, dilakukan dengan menghitung waktu standar dengan menggunakan metode Stopwatch Time Study. Hasil perhitungan beban kerja mental operator SPBU menunjukkan beban kerja mental yang didapatkan operator berlebih dengan total rata-rata sebesar 77,35. Dimana indikator beban kerja mental yang memiliki skor tertinggi yaitu effort, temporal demand, dan physical demand. Dan hasil perhitungan tingkat kelelahan kerja operator 37,75 dengan klasifikasi kelelahan sedang. Setelah dilakukan perhitungan waktu standar, terjadi penyesuaian waktu kerja. Dimana waktu siklus rata-rata kerja sebelumnya 8,24 menit menjadi 12,29 menit. Penyesuaian waktu kerja merupakan persentase penurunan 3 indikator tertinggi beban kerja mental operator. Setalah dilakukan perhitungan untuk menurunkan beban kerja mental, skor akhir yang didapatkan adalah 52,30 dengan klasifikasi beban kerja mental optimal load dan kenaikan persentase utilitas stasiun pengisian bahan bakar sebesar 32%.

Abstract Background Within surgery, assistive robotic devices (ARD) have reported improved patient outcomes. ARD can offer the surgical team a “third hand” to perform wider tasks and more degrees of motion in comparison with conventional laparoscopy. We test an eye-tracking based robotic scrub nurse (RSN) in a simulated operating room based on a novel real-time framework for theatre-wide 3D gaze localization in a mobile fashion. Methods Surgeons performed segmental resection of pig colon and handsewn end-to-end anastomosis while wearing eye-tracking glasses (ETG) assisted by distributed RGB-D motion sensors. To select instruments, surgeons (ST) fixed their gaze on a screen, initiating the RSN to pick up and transfer the item. Comparison was made between the task with the assistance of a human scrub nurse (HSNt) versus the task with the assistance of robotic and human scrub nurse (R&HSNt). Task load (NASA-TLX), technology acceptance (Van der Laan’s), metric data on performance and team communication were measured. Results Overall, 10 ST participated. NASA-TLX feedback for ST on HSNt vs R&HSNt usage revealed no significant difference in mental, physical or temporal demands and no change in task performance. ST reported significantly higher frustration score with R&HSNt. Van der Laan’s scores showed positive usefulness and satisfaction scores in using the RSN. No significant difference in operating time was observed. Conclusions We report initial findings of our eye-tracking based RSN. This enables mobile, unrestricted hands-free human–robot interaction intra-operatively. Importantly, this platform is deemed non-inferior to HSNt and accepted by ST and HSN test users.

The workload is highly related to efficient and effective human resource utilization in an organization to achieve organizational objectives, vision, and mission. Various methods are used to optimize the number of personnel in an organization so that each task can be completed quickly and precisely. Accounting Institutions are inseparable from problems regarding the lack of workload with the number of personnel working on it. The change of the Policy gives an impact on the change of Job Description and List of Personnel Arrangements of the organization. To overcome these issues, workload measurement, analysis can be used to determine the optimal amount of personnel required in their working units. This study uses a mental workload measurement so called NASA-TLX and physical workload measurement According to the applicable workload regulation that is in accordance with the Administrative Direction of Workload Analysis. Both methods are then carried out to be compared to each other. The results showed that the physical workload is required in the completion of tasks in each work unit. In addition, the determination of the optimal number of personnel using physical workload or appropriate tasks per task position based Job Description is performed. As a result, it is known that there is an excessive workload in the Sub Service Budget Cost work units with personal shortcomings. On the other hand, there is an excessive personnel number in Administrative Work, Sub Department of Finance Administration and Sub Department Financial Control. The overall conclusion of this study is a need for personnel reduction in a List of Personnel Arrangements currently known as Accounting Institutions to be 39 personnel instead of the existing 48 personnel.  Keywords: Workload, NASA-TLX (Task Load Index), assignments Per Task title, Number of Optimal personnel

The workload of an organization is related to the efficient and effective utilization of human resources so that it can realize the vision, mission and objectives of the organization. Various methods are used to optimize the number of personnel in an organization, so that each task can be completed effectively and efficiently. KRI Diponegoro-365 personnel as the TNI Maritime Task Force, the Garuda Contingent can not be separated from the problems regarding the lack of conformity to workload with the allocation of the number of available personnel. To overcome this, an analysis of workload measurement is needed which can then be used for determine the allocation of the right number of personnel needed in each division. This study uses the measurement of NASA-TLX mental workload and physical workload according to TNI Roles. Both of these methods are then compared between mental and physical burden that occurs. From the results of the comparison, it was found that physical workload is needed in the completion of tasks in each division. After a comparison, then the determination of the allocation of the number of personnel will be carried out using the physical workload approach based on the description of the tasks in each division. The results of the calculation will then show the division that has excess or lack of personnel. The overall results obtained from this study can be concluded that the number of maritime task force personnel using the Diponegoro class KRI is appropriate, but the allocation of personnel in each division needs to adjust to the existing workload.  Keywords: Workload, NASA-TLX (Task Load Index), Number of Military Personnel

Pandemi telah mengubah semuanya tidak terkecuali Indonesia. Pemerintah kembali memperbarui data pandemi virus Corona (COVID-19) di Tanah Air. Tanggal 1 Juni 2021, sebanyak 4.824 tambahan kasus baru, 5.360 kasus sembuh dan 145 kasus meninggal akibat COVID-19. Pemerintah melaporkan sebanyak 4.824 kasus baru, sehingga total positif Corona di Indonesia menjadi 1.826.527 kasus. Ada pula penambahan kasus sembuh sebanyak 5.360, dengan demikian, total kasus sembuh dari Corona mencapai 1.674.479 kasus. Terlebih hal ini terjadi karena penyebaran COVID-19 terjadi melalui interaksi antar sesama yang menyebabkan perlunya social distancing untuk diterapkan di masyarakat. Adanya social distancing ini mengurangi aktivitas bersama dengan lainnya. Masalah kesehatan mental yang muncul akibat pandemi COVID-19 dapat berkembang menjadi masalah kesehatan yang dapat berlangsung lama dan berpotensi menimbulkan beban sosial yang berat. Kesehatan mental adalah aspek penting dalam mewujudkan kesehatan yang menyeluruh. Namun di sebagian besar negara berkembang, masalah kesehatan mental belum diprioritaskan apabila dibandingkan dengan penyakit menular. Hasil penelitian pendahuluan diperoleh dari data mahasiswa yang melakukan praktikum secara daring bahwa mahasiswa mengalami kelelahan dalam praktikum sebanyak 64,3%, peningkatan tingkat stress sebanyak 78,3%, berkurangnya konsentrasi sebanyak 71,3%, tekanan dalam praktikum sebanyak 66,7%, keluhan kesehatan sebanyak 38%, penurunan tingkat kewaspadaan 40,3%, rasa kantuk yang menggannggu sebanyak 72,9%, dan bekerja yang berlebihan 58,1%.

IntroductionLearner workload during simulated team-based resuscitations is not well understood. In this descriptive study, we measured the workload of learners in different team roles during simulated paediatric cardiopulmonary resuscitation.MethodsPaediatric emergency nurses and paediatric and emergency medicine residents formed teams of four to eight and randomised into roles to participate in simulation-based, paediatric resuscitation. Participant workload was measured using the NASA Task Load Index, which provides an average workload score (from 0 to 100) across six subscores: mental demand, physical demand, temporal demand, performance, frustration and mental effort. Workload is considered low if less than 40, moderate if between 40 and 60 and high if greater than 60.ResultsThere were 210 participants representing 40 simulation teams. 138 residents (66%) and 72 nurses (34%) participated. Team lead reported the highest workload at 65.2±10.0 (p=0.001), while the airway reported the lowest at 53.9±10.8 (p=0.001); team lead had higher scores for all subscores except physical demand. Team lead reported the highest mental demand (p<0.001), while airway reported the lowest. Cardiopulmonary resuscitation coach and first responder reported the highest physical demands (p<0.001), while team lead and nurse recorder reported the lowest (p<0.001).ConclusionsWorkload for learners in paediatric simulated resuscitation teams was moderate to high and varied significantly based on team role. Composition of workload varied significantly by team role. Measuring learner workload during simulated resuscitations allows improved processes and choreography to optimise workload distribution.

Abstract Objective We evaluated perceived workload (measured by the NASA Task Load Index; NASA-TLX) as related to Symbol Digit Modalities Test (SDMT) performances in monolingual and bilingual traumatic brain injury (TBI) survivors and healthy comparison participants (HC). Method The sample consisted of 28 TBI survivors (12 monolinguals & 16 bilinguals) and 50 HC (20 monolinguals & 30 bilinguals). SDMT written (SDMT-W) and SDMT oral (SDMT-O) were used to evaluate group differences. Results ANCOVA, controlling for age, revealed that the HC group outperformed the TBI group on SDMT-W, p = .001, and SDMT-O, p = .047. Furthermore, bilinguals outperformed monolinguals on SDMT-W, p = .017. On the NASA-TLX, an interaction emerged on temporal demand rating, p = .023, with TBI bilinguals reporting higher temporal demand on SDMT tasks compared to TBI monolinguals, while the HC monolingual participants reported higher temporal demands ratings compared to HC bilingual participants. Furthermore, monolingual participants showed higher levels of frustration with regard to the SDMT task compared to bilingual participants, p = .029. Conclusion Our data revealed TBI survivors underperformed on both SDMT trials compared to the HC participants. Also, bilingual participants demonstrated better SDMT-W performances compared to monolingual participants. Furthermore, our TBI bilingual sample reported themselves to be more rushed to complete the SDMT compared to monolingual TBI sample, but they were less frustrated. Meanwhile, our HC monolingual sample felt more rushed to complete the SDMT tasks compared to HC bilingual participants, but they were less frustrated. While we observed differences in workload ratings between language groups, it is unclear if language use, and/or other variables are driving these results.

Abstract Purpose Results of a study to determine whether reducing pharmacy phone call workload through implementation of a pharmacy services call center (PSCC) led to decreased employee workload, improved efficiency, and increased pharmacist availability for patient care are reported. Methods A pre–post study was conducted using the NASA Task Load Index (NASA-TLX) instrument. Pharmacists, pharmacy technicians at 7 academic health center community pharmacies, and PSCC staff provided NASA-TLX data over 5 days during 3 data collection periods before and after PSCC implementation. Perceived workload was measured as an overall workload score (OWS) and mean scores for 6 NASA-TLX workload dimensions (mental demand, physical demand, temporal demand, performance, effort, and frustration). Results Relative to pre-PSCC values, mean postimplementation OWS scores significantly decreased in all 7 pharmacies (from 33.3 to 29.1 overall, p < 0.001) but especially in small pharmacies (from 31.7 to 27.6, p < 0.001). Scores for the physical demand and frustration dimensions were low in both the PSCC and in the 7 pharmacies, while scores for the performance dimension remained high (range, 6.8–8.3). In general, scores for all other measured NASA-TLX dimensions decreased after PSCC implementation, more so at smaller pharmacies. The PSCC staff mean OWS score increased over time (from 26.8 to 28.6, p < 0.0001) but remained near the overall pharmacy average of 29.1. Conclusion Use of the NASA TLX allowed for a direct subjective measurement of workload as perceived by pharmacy and PSCC employees before and after PSCC implementation. Long-term effects of the PSCC on workload should be assessed.

Background: Performing cardiopulmonary bypass is a complex task which involves evaluating visual input from patient monitors and technical parameters displayed at the heart-lung machine console as well as reacting to other sensory input. Only few studies are available concerning the competency requirements for clinical cardiovascular perfusionists, including attention, perception, and coping with mental stress. This study aims at evaluating attention, perception, and stress levels of clinical cardiovascular perfusionists during cardiopulmonary bypass. Methods: Nine clinical cardiovascular perfusionists voluntarily offered to participate in the study. Participants were asked to wear Tobii 2 eye-tracking glasses throughout the procedures. Specific time points were analyzed (cardiopulmonary bypass on, initial cardioplegia delivery, steady state, cross-clamp off, and weaning from cardiopulmonary bypass). Data acquisition was supplemented by participants’ self-evaluation regarding their stress levels and by National Aeronautics and Space Administration Task Load Index (NASA TLX) questionnaires. Results: Seven datasets were sufficient to be evaluated. The clinical cardiovascular perfusionists’ professional experience ranged from 0.5 to 24 years. Evaluation of eye-tracking data revealed large variations in areas of interest hits, fixation, and dwell times. Across all phases, the venous reservoir, mean arterial pressure, arterial pump display, cardioplegia control, and data management system received the highest levels of attention. Pupil diameter measurements increased at start of cardiopulmonary bypass, cardioplegia delivery, and weaning off, but returned to base level during steady state. Clinical cardiovascular perfusionists’ self-evaluation showed that subjective stress level was highest at the start and the end of the procedure. NASA TLX questionnaires revealed medium-to-high mental and temporal workloads, but low physical workloads. Performance, effort, and frustration indices showed medium workloads. Conclusion: During cardiopulmonary bypass, perfusionists are subjected to stress. Peak stress levels were highest during start and end of cardiopulmonary bypass. Furthermore, visual attention and perception varied between the operative phases. Further studies are indicated to evaluate the design of heart-lung machines and stress-coping strategies during cardiopulmonary bypass.
