Some major accidents on offshore platforms are caused by a lack of awareness and fatigue experienced by workers. Fatigue and lack of awareness in some literature is caused by a lack of good quality and quantity of sleep. The quality and quantity of sleep is affected by the sleep hygiene practiced by workers, the conditions of accommodation and work shifts performed. This study aims to observe of the quantity and quality of sleep, the relationship between sleep hygiene and the quality and quantity of sleep, and to observe the relationship between sleep quality and the aspects of alertness and fatigue experienced by workers. The research was conducted at the offshore platform of PT. X, with 24 workers responding to the questionnaire, and 22 workers using actigraphy tools. Actigraphic data collection was carried out for 14 working days and divided into three different shift groups. From the PSQI 63.1% of respondents had poor sleep quality and 36.9% of respondents had good sleep quality. The lowest average sleep duration based on data collection with actigraphic devices was obtained during the night shift (300 minutes), while the highest sleep duration was obtained by non-shift workers (358 minutes). Actigraphy data shows that the average sleep duration with HVAC A longer than using HVAC B. There were 59.5% of respondents experiencing normal fatigue and 40.5% of respondents experiencing mild fatigue. Almost all respondents had good sleep hygiene (95.2%) and there was no relationship between sleep hygiene and sleep quality. There was no relationship between sleep quality and worker alertness (p-value:0,466). And there is no relationship between sleep quality and worker fatigue (p-value: 0.062)
Kegiatan pemboran merupakan salah satu aktivitas yang berpotensi dropped object di industri minyak dan gas bumi lepas pantai. Dropped object dapat menyebabkan cidera serius bahkan kematian, kerusakan peralatan dan lingkungan. Tujuan penelitian ini adalah mengetahui hubungan persepsi, pengetahuan, sikap dan kemampuan menghindari bahaya dropped object dengan perilaku tidak aman pada pekerja di rig pemboran lepas pantai. Desain penelitian cross sectional, menggunakan kuesioner, analisis data mengunakan chi square. Hasil telitian menunjukkan hubungan persepsi, pengetahuan, sikap dan kemampuan menghindari bahaya dropped object dengan perilaku tidak aman. Disarankan bagi perusahaan untuk melakukan pelatihan dan pelatihan penyegaran yang berhubungan dengan pencegahan dropped object, memasukkan materi Alat Identifikasi Bahaya dan Kepedulian Dropped Object dalam induksi keselamatan, meningkatkan program Behavior Based Safety dan pengawasan supervisor. Terkait dropped object incident yang telah terjadi disarankan untuk melakukan dropped object incident study.
Drilling is one of activity in offshore oil and gas industry that has dropped object potential. Serious injury, fatality, property damage and environmental pollution can be resulted from dropped object. The purpose of this study is to find out associations between perception, knowledge, attitude, ability to avoid dropped object hazard and unsafe behavior among workers in offshore drilling rig. Cross sectional design is used, using questionnaire and chi square for data analysis. The results shows there is significant relationship between perception, knowledge, attititude, ability to avoid dropped object hazard and unsafe behavior. It is recommended to conduct training and refreshing training related to dropped object prevention, Hazard Identification Tool and Dropped Object Awareness should be included in safety induction, improve Behavior Based Safety program and supervisor supervision. and dropped object incident study should be conducted related to dropped object incidents that occurred.
As a workplace, office environments have significant hazards and risks associated with the interactions between human and computer. The consequences that may arise are related with the healthy state of worker, direct and indirect financial impact, and company productivity impact. In order to protect the workers, company assets and facilities; a comprehensive office ergonomics program is required to manage the risk factors of musculoskeletal disorders. As a start, necessary measures are required to improve the knowledge and perceptions of workers in the aspects of office ergonomics. Knowledge and perception are the foundation to achieve healthy behavioral changes. The healthy behavioral change is required for workers to control the risk factors of musculoskeletal disorders. Education, in the form of training, acts as one of critical factors to increase knowledge and perception. This study is performed to analyze the effect of office ergonomics training intervention on the knowledge and perception of office workers at PT XYZ. Quasi-experimental research was selected by involving both, the intervention and comparison groups. Two treatments were given to the intervention group, they are self-learning type intervention and online office ergonomics training intervention. Only one treatment was given to the comparison group, the self-learning intervention. Based on the research, it is concluded that the online office ergonomics training increased the knowledge and overall perceptions of the office workers of PT XYZ. Online office ergonomics training gave a more significant influence than the self-learning type intervention.
