The making of Indonesian soccer robot in the division of the Indonesian Football Robot Contest (KRSBI) especially in the process of coil rolling machines on a solenoid does not pay attention to ergonomic factors. The process of winding the wire on the solenoid is done using only the hands manually and in an un ergonomic body position, which is turning and bending. As a result, the convolution process lasts longer and in the wrong posture, causing fatigue and back pain. Macroergonomic Analysis and Design (MEAD) and Rapid Entire Body Assessment (REBA) approaches are used to analyze the posture of the wire. The solution is obtained by design and making an ergonomic and semi-automatic coil rolling machines to solenoid Robot based on the Arduino Microcontroller

Low back pain (LBP) is one of the most common health complaints in the community. About 80 percent of adults have experienced this condition. This research is a quantitative research with a cross sectional approach. The study was conducted at the Ulos Sianipar Gallery onAugust 2021. The population in this study were all weavers who worked at the Ulos Sianipar Gallery Medan as many as 54 people by using the slovin formula obtained sample of 48 people. Data was collected through a questionnaire, specifically for work attitudes with the Rapid Entire Body Assessment (REBA) method, carried out with the help of cameras, bows and worksheets. The results showed that individual factors: age (p=0.003), body mass index (p=0.044) and length of work (p=0.022); work environment factors: work duration (p=0.020) and rest time (p=0.018); and work factors: workload (p=0.001) and work attitude (p=0.001) have a relationship with LBP on weavers at Galeri Ulos Sianipar Medan. It is recommended for business owners to adjust the position of the thread on the weaving machine to the sitting position of the worker so that it does not require the worker to raise his hand higher, the weaver is advised to reduce or avoid awkward postures such as bending over which can cause muscle fatigue due to frequent or repetitive weaving.

Background and Objectives: This study aimed to determine the prevalence rate of musculoskeletal disorders and evaluate the body position in routine tasks among orthotists and prosthetists. Methods: Forty orthotists and prosthetists were included. The scores of the Nordic Musculoskeletal Questionnaire and the Rapid Entire Body Assessment were used to determine the prevalence rate of musculoskeletal disorders and analyze the work position of orthotists and prosthetists, respectively. An examiner evaluated 10 working postures that were dominantly used every day, in each orthotist and prosthetist. Results: Among the orthotists, 55.6% of men and 47% of women suffered from pain in the trunk, neck, and lower limbs. Nearly similar results were seen in the upper limbs (74.1% men and 45.5% women). Such high prevalence rates were not seen in prosthetists. The analysis of the Rapid Entire Body Assessment scores based on the working task and gender of the orthotist and prosthetist showed that more than 60% of the workers achieved a score of 4 to 7 approximately in half of the tasks. It shows the medium risk of musculoskeletal disorders, thus, corrective action is necessary. Conclusion: Based on the findings, musculoskeletal disorders are highly prevalent among orthotists and prosthetists, especially in the orthotist workers. To reduce these disorders, it is recommended to add ergonomic topics and training courses for working with devices to increase the knowledge of specialists and apply and select practical tools based on the principles of ergonomics.

The metal casting industry, Nitikan is a micro business whose production process is carried out manually. The equipment used is simple and without considering the user's health. This can be seen in the product finishing process that uses a sanding machine. The equipment is not designed according to the user's posture so the operator bends in doing work movements, of course this is very risky to experience lower back pain injuries. This study aims to analyze the work activities of the finishing process using the Rapid Entire Body Assessment (REBA) and Rapid Upper Limb Assessment (RULA) approach and design work tools that can be applied to improve work posture. The results of data processing and analysis obtained a Rapid Entire Body Assessment score on a sandpaper machine single head of 5 and a Rapid Upper Limb Assessment score of 4, the score indicates that the work position has the potential to experience a risk of low back pain, so there must be an improvement in work posture. Work posture improvement is done by designing a tool in the form of a sandpaper machine that takes into account ergonomic dimensions to reduce the risk of lower back injury. The final result after the improvement is obtained Rapid Entire Body Assessment score of 3 and Rapid Upper Limb Assessment score of 4. This shows that the risk of lower back injuries can be minimized.

Low back pain (LBP) merupakan sebuah sindrom klinis ditandai dengan timbulnya gejala nyeri di sekitar punggung bawah yang tanpa atau dapat disertai penjalaran pada tungkai bawah. Posisi tidak ergonomis seperti membungkuk, memiringkan badan, dan posisi menggapai atau berlutut yang dapat menyebabkan beberapa dampak, salah satunya LBP. Penelitian ini dilakukan untuk menganalisis hubungan postur tubuh dan lama berdiri dengan kejadian LBP pada pekerja bidang produksi dan logistik di Cikarang. Penelitian ini menggunakan analitik observasional dengan desain penelitian potong lintang karena membahas dua variabel (independen dan dependen) selanjutnya diobservasi atau diukur hanya sekali pada setiap variabel dalam waktu yang sama. Sampel penelitian berjenis kelamin lakilaki, berjumlah 62 responden, berusia 18-40 tahun dengan kata lain termasuk kriteria inklusi dan teknik pengambilan sampel berupa simple random sampling. Analisis postur tubuh menggunakan Rapid Entire Body Assessment (REBA), untuk lokasi serta pengukuran intensitas nyeri LBP menggunakan kuesioner Nordic Body Map (NBM) dan Numeric Rating Scale (NRS), analisis bersifat kuantitatif karena didasarkan pada skala yang tersedia pada kategori setiap instrumen penelitian. Hasil uji Fisher hubungan postur tubuh dengan kejadian LBP diperoleh nilai signifikansi p=1,000 (p> 0,05) dan untuk lama berdiri dengan kejadian LBP didapatkan nilai signifikansi p=0,067 (p> 0,05). Kesimpulan hasil tersebut tidak terdapat hubungan antara postur tubuh dan lama berdiri dengan kejadian LBP pada pekerja. Hal ini dapat dipengaruhi usia pekerja yang dominan termasuk kategori usia produktif sehingga sifat fisiologis otot masih sangat menunjang produktivitas kerja. Selain itu disela-sela kegiatan, para pekerja dapat leluasa melakukan peregangan minimal pada tubuhnya sehingga kekakuan pada otot di sekitar punggung bawah dapat dihindari.

A morphing trailing-edge (TE) wing is an important morphing mode in aircraft design. In order to explore the static aeroelastic characteristics of a morphing TE wing, an efficient and feasible method for static aeroelastic analysis has been developed in this paper. A geometrically exact vortex lattice method (VLM) is applied to calculate the aerodynamic forces. Firstly, a typical model of a morphing TE wing is chosen and built which has an active morphing trailing edge driven by a piezoelectric patch. Then, the paper carries out the static aeroelastic analysis of the morphing TE wing and corresponding simulations were carried out. Finally, the analysis results are compared with those of a traditional wing with a rigid trailing edge using the traditional linearized VLM. The results indicate that the geometrically exact VLM can better describe the aerodynamic nonlinearity of a morphing TE wing in consideration of geometrical deformation in aeroelastic analysis. Moreover, out of consideration of the angle of attack, the deflection angle of the trailing edge, among others, the wing system does not show divergence but bifurcation. Consequently, the aeroelastic analysis method proposed in this paper is more applicable to the analysis and design of a morphing TE wing.

Background: The automotive industry is heavily affected by sick leaves caused by the handling of loads and using postures that produce musculoskeletal disorders. Research is needed to analyse their causes and find possible solutions to eliminate or mitigate these risks. Objective: Our objective was to analyse the level of musculoskeletal risk in the different work tasks performed by truck and bus mechanics. Our intention is also to analyse whether postural training and feedback can help reduce risk. Methods: The rapid entire body assessment (REBA) was used to assess the postures performed by 35 mechanics from eight branches throughout Spain. The participants were subsequently divided randomly into two groups (experimental group and control group). The experimental group (EG) was given training and feedback on their postures and the control group (CG) was not offered any type of intervention. A few months after the initial assessment, their postural load in the usual tasks was re-evaluated. Results: An overall average REBA Score: 10.49 ± 1.33. The main risk was found in the trunk and arms with sustained above-the-head postures. EG’s second results are significantly improved compared to the first (p = 0.026 *). Conclusions: These jobs have a high-risk level of musculoskeletal disorders. The course of action presented with postural training and feedback has shown satisfactory results. Nevertheless, given the size of the sample, further research will be needed to delve deeper into this possibility as a future line of intervention.
