Gangguan otot rangka yang sering dialami pekeija manual material handling salah satunya disebabkan oleh besarnya beban mekanik yang diterima tubuh terutama pada L5/SI (lumbosacral joint) tidak pernah dapat diperkirakan secara tepat hingga saat ini. Beban mekanik yang berlebihan jika melampaui batas kemampuan struktur tubuh dapat menyebabkan cedera. Salah satu pendekatan yang dapat digunakan untuk memperkirakan besarnya gaya internal otot akibat pengaruh berat tubuh dan beban ekstemal adalah dengan menggunakan model matematis. Operator boiler pada industry pengolahan kayu bertugas memasukkan bahan bakr ke dalam boiler melaksanakan pekerjaan dalam 3 postur yaitu mengangkat (loading), membawa (carrying) dan memasukkan (unloading) bahan bakar. Postur kerja tersebut menimbulkan keluhan berupa rasa sakit/nyeri pada pinggang, punggung, bahu dan lengan. Dalam penelitian ini metodologi yang digunakan adalah descriptive dengan pendekatan observasional terhadap 7 (tujuh) orang operator boiler di 2 (dua) industry kayu di Kota Padang. Berdasarkan analisis biomekanik terhadap ke 3 (tiga) postur kerja diketahui bahwa postur loading menimbulkan gaya dan momen terbesar pada L5/S1, bending moment 92.35 Nm, compression force 1889.43 dan sharing force (Anterior/Posterior) 113 N. Pengujian compression force dengan menggunakan Spinal Compression Tolerance Limit (SCTL) pada nilai 50% ile dari tekanan yang ditrima oleh tulang belakang operator diperoleh 28 % dari SCTL artinya tekanan tersebut masih dalam toleransi (< 30 % dari SCTL). Persentase perbandingan terhadap rekomendasi NIOSH untuk bending moment 163 Nm diperoleh 56.66 % untuk compression force 3425 N diperoleh 55.17 % dan shearing farce 1000 N dipero!eh 11.3 % dari rekomendasi. Perbandingan gaya dan momen tersebut seluruhnya masih berada dalam batas rekomendasi NIOSH. tetapi yang perlu diperhatikan adalah untuk compression force, berdasarkan kurva Load Deformation gaya tersebut telah menyebabkan L5/S1 terdeformasi ± 0.7 mm pada endplate (inward deformation). Bending moment dan compression farce yang cukup besar pada L5/S J saat postur loading merupakan dasar bagi perancangan perubahan postur tubuh. Pembuatan tempat penampungan dengan ketinggian 75 em dapat menurunkan gaya dan momen secara signifikan. Persentase penurunan yang tetjadi untuk bending moment sebesar 58.08 %, compression force 73.67 % dan shearing force sebesar 50.08 %. Potensi cedera yang terjadi diharapkan dapat berkurang dengan menurunnya beban mekanik yang diterirna tubuh operator boiller.
Fatigue is one of the cause of accidents. The objective of this study is to examineacute fatigue potential based on a Occupational Fatigue Exhaustion Recovery(OFER) scale and types of heavy equipment, analyze the relationship betweenwork-related fatigue (duration, workload and shift work), response to non-work-related fatigue (age, nutritional status, commuting time, the number of hours ofsleep) with the occurrence of fatigue on heavy equipment operator. This researchwas conducted from April until July 2016 at heavy equipment operator in themine area 1 Bukit Karang Putih. Number of study respondents 50 people. Thestudy is observational quantitative research with cross-sectional method.Measurement of fatigue using a OFER scale and the results show that 48% ofrespondents experiencing moderate acute fatigue, 44% of dump truckexperiencing high acute fatigue, shift has significant correlation with high andmoderate acute fatigue potential (p value = 0.027). recomendation to company PTSemen Padang to provide education or training about risk factor fatigue to heavyequipment operator.Keywords:Acute fatigue, Heavy Equipment Operator Fatigue, OFER Scale, Shift
Machines and work equipments that have no protection (guarding), lack of maintenance, working without concerned about safety, and workers who frequently having occupational injury indicate that in Indah Jati Furniture has safety risk of mechanical hazards arising the use of machinery and work equipment. The purpose of the study is to assess the safety risk of mechanical hazards.
Palu and Gorontalo cities are provincial capitals located on Sulawesi Island, Indonesia. In 2018, the city of Palu was hit by the earthquake, tsunami disaster and liquefaction which a phenomenon that caused thousands of people to lose the world and thousands of people had to be displaced. Potential disasters and emergencies also discussed Gorontalo City which is different from Palu City. Natural disasters have an impact on workers and companies, including the hospitality industry. Not only natural disasters, emergency situations in the hotel industry can also occur due to non-natural disasters or social disasters. This study aims to increase the level of emergency and disaster preparedness in the hotel sector in Palu and Gorontalo. The method used in this study is a questionnaire adopted from APEC tourism risk management and tourism resilience index. Focus Group Discussions and Interviews were also conducted to discuss the implementation of emergency and disaster management in the workplace. The results of the multiple correspondence analysis of emergency preparedness and disaster management factors in hotels in Palu are relatively closer to the medium rating, while the emergency and disaasters preparedness factors in Gorontalo were relatively on the low categories for research variables. Based on these results, the participation of the private sector (hospitality industry) and the government is needed to build synergy in disaster risk reduction programs both locally and nationally
Salah satu kegiatan pelayaran berada pada industri minyak dan gas yang menggunakan kapal tanker dengan berbagai macam ukuran. Sehingga lalu lintas pelayaran pun semakin ramai yang dapat menyebabkan kecelakaan pelayaran. Maka dari itu, operator kapal tanker harus memastikan keselamatan seluruh orang selama kapal tanker beroperasi demi terciptanya keselamatan pelayaran dengan menerapkan standar industri Migas yaitu Tanker Management and Self-Assessment (TMSA). Penelitian ini bertujuan untuk menganalisis kompetensi operator kapal tanker dalam menerapkan standar industri dalam rangka terciptanya keselamatan pelayaran. Penelitian ini merupakan penelitian kualitatif pada 5 perusahaan operator kapal tanker yang dianalisa pada penerapan 13 elemen TMSA. Hasil penelitian menunjukan bahwa dari 5 perusahaan yang menerapkan TMSA yaitu 1 perusahaan asing dan ke-empat perusahaan lainnya tidak menerapkan TMSA.
One of the shipping activities is in the oil and gas industry which uses tankers of various sizes. So that the shipping traffic is getting more crowded which can cause maritime accidents. Therefore, tanker operators must ensure the safety of all people while the tanker is operating in order to create shipping safety by applying oil and gas industry standards, namely Tanker Management and Self-Assessment (TMSA). This study aims to analyze the competence of tanker operators in applying industry standards in order to create shipping safety. This research is qualitative researchon 5 tanker operator companies analyzed on the application of 13 elements of TMSA. The results showed that of the 5 companies that implemented TMSA, namely 1 foreign company and the other four companies did not implement TMSA.
