Incorrect sitting posture can lead to damage in our bones and muscles.

The correct answer is keyboard QWERTY. This is because QWERTY is the most commonly used keyboard layout worldwide. It was designed in the 19th century and is named after the first six letters on the top row of keys. The QWERTY layout is used in many countries and is standard on most computers and typewriters. It is known for its arrangement of keys that is optimized for typing efficiency and has become the standard choice for keyboards in the majority of countries.

The correct answer is "Posisi meja antara 60 – 75 cm dari bawah." This is because having the desk at this height allows for comfortable use of the computer. It ensures that the user's arms are at a comfortable angle and that they can easily reach the keyboard and mouse without straining their wrists or shoulders. Additionally, having the desk at this height promotes good posture and reduces the risk of developing musculoskeletal disorders.

The correct answer is "Tabung pemadam kebakaran" because it is necessary to have fire extinguishers in a computer lab to ensure safety in case of fire emergencies. The other items listed, such as minyak kayu putih, karpet, komputer, and kipas angin, are not essential safety equipment for a computer lab.

The given answer suggests that providing a narrow space for mouse movement is not a correct position or arrangement for the mouse according to K3 (occupational health and safety). This is because a narrow space restricts the movement of the mouse, making it difficult to move the mouse easily and comfortably.

The study of K3 (Kesehatan dan Keselamatan Kerja) combines various disciplines such as health sciences, behavioral sciences, natural sciences, technology, and more. By studying K3LH, we aim to create a healthy and safe working environment for employees. This includes ensuring their well-being, promoting safety measures, and preventing accidents or health hazards. Ultimately, the goal is to improve efficiency and productivity in the workplace by prioritizing the health and safety of workers.

The correct answer is that the elbow should form an angle of 90° to 110° with the position of the keyboard. This is because maintaining this angle helps to reduce strain on the muscles and tendons in the forearm and wrist, preventing conditions such as carpal tunnel syndrome. It also promotes proper alignment of the arm and hand, allowing for comfortable and efficient typing or mouse use.

The correct answer is "Memakai gelang anti statik." This is because in the given list of safety measures in TKJ (Teknik Komputer Jaringan), wearing an anti-static bracelet is important. This bracelet helps to prevent the build-up and discharge of static electricity, which can be harmful to electronic components. By wearing the bracelet, it ensures that any static charges are safely grounded, reducing the risk of damage to sensitive equipment during assembly or repair.

Continuous use of a computer can lead to various physical and mental issues such as eye strain (mata merah), lack of concentration (tidak konsentrasi), fatigue (lelah), and headaches (kepala pusing). However, it does not cause stiffness in the leg muscles (otot kaki kaku).

Occupational overuse syndrome is a condition that occurs due to repetitive movements or overuse of certain muscles or tendons. Symptoms of this syndrome include fatigue, burning sensation, muscle discomfort, and stiffness. However, fever is not a symptom of occupational overuse syndrome.

The normal working temperature range is generally considered to be between 22°C to 28°C. This range provides a comfortable environment for most individuals to work in without feeling too hot or too cold. Temperatures below or above this range may cause discomfort and affect productivity. It is important to maintain a suitable working temperature to ensure the well-being and efficiency of employees.

The given answer states that the surface supporting the mouse and keyboard should be flat. This is important because a flat surface allows the mouse to move smoothly and accurately, ensuring precise cursor movement. It also provides stability for the keyboard, preventing it from wobbling or moving during typing. A flat surface is necessary for optimal performance and ease of use for both the mouse and keyboard.

The correct answer is that the position of the top of the text on the monitor should be aligned with our eyes. This is important for ergonomic reasons as it helps to prevent strain on the neck and eyes. When the text is positioned too low, we may need to tilt our head downwards, which can lead to discomfort and fatigue. Therefore, it is recommended to position the top of the text at eye level to maintain a comfortable and ergonomic viewing position.

The correct answer is "penggantian, isolasi atau relokasi peralatan yang berisik" because it suggests replacing, isolating, or relocating noisy equipment as a standard method to reduce noise. This option addresses the root cause of the noise and offers a more effective solution compared to simply covering the machine with cloth or plastic, using soundproofing materials, or using wooden ceilings.

The correct answer is "Kesehatan, Keselamatan, Keamanan Kerja dan Lingkungan Hidup". This is the correct abbreviation for K3LH, which stands for Keselamatan, Kesehatan, Keamanan Kerja dan Lingkungan Hidup.

Gerakan alat adalah jawaban yang benar karena faktor-faktor lain yang disebutkan dalam pertanyaan, seperti posisi tubuh, gerakan kerja, tenaga yang dikeluarkan, dan penglihatan, semuanya berkontribusi terhadap tingkat ergonomis tempat kerja. Namun, gerakan alat tidak secara langsung mempengaruhi tingkat ergonomis tempat kerja, karena faktor ini lebih berkaitan dengan desain dan penggunaan alat daripada ergonomi langsung pada tempat kerja.

The correct answer is "antara 30cm atau membentuk sudut 30°". This means that the recommended distance between the eyes and the monitor should be either 30cm or form an angle of 30°. This is important for maintaining good eye health and reducing strain while using the monitor.

A good work organization is important in ensuring a comfortable and safe working environment with computers. This includes factors such as clear job roles and responsibilities, effective communication channels, efficient workflow processes, and a supportive work culture. A well-organized work environment can help reduce stress, improve productivity, and minimize the risk of health issues related to computer use.

The suggested range for the distance between the screen and the eyes to ensure comfort is 45-80 cm. This range allows for a comfortable viewing experience without straining the eyes or causing discomfort. It is important to adjust the distance according to individual preferences and visual needs.
