The purpose of this research was to determine the extent of the influence of Body Mass Index (BMI) Variations on musculoskeletal discomfort. The steps taken are first to calculate the Body Mass Index (BMI), measure the level of musculoskeletal discomfort of each cleaning worker who works in an elevated place by distributing the Nordic Body Map questionnaire, then perform a statistical test with the Chi-Square Test. The results of this research are painful areas of musculoskeletal discomfort is the left shoulder, right shoulder, back, waist, buttocks, right knee and left leg. From the Chi-Square Test results obtained p-value for the left shoulder = 0.006, right shoulder = 0.003, back = 0.00, waist = 0.00, buttocks = 0.00, right knee = 0.001 and left leg = 0.00, because all <0.05 then all null hypotheses are rejected, this fact means there is a relationship between BMI and musculoskeletal discomfort that is felt sick. The conclusion is an un-ergonomic posture in the work will cause the musculoskeletal discomfort area and the higher the person's BMI level will be susceptible to pain complaints, the lower the BMI than the fewer complaints of pain.

Dalam Statistical Process Control, seven tools atau piranti perbaikan kualitas sering digunakan untuk pengendalian proses statistik dan dapat membantu dalam menetapkan kemampuan proses dengan melakukan pengukuran terhadap variasi produk yang dihasilkan dan secara grafis memungkinkan menetapkan sebuah proses berada di dalam atau di luar batas kontrol. Kualitas botol kemasan plastik 60 ml yang baik sangat dibutuhkan, karena ini berhubungan dengan kepuasan pelanggan. Seven Tools atau piranti perbaikan kualitas yang digunakan untuk menganalisis permasalahan tersebut adalah Check Sheet, Control Chart, Histogram, Fish Bone Diagram, Brainstorming, Pareto Diagram dan Scatter Diagram. Semua piranti ini digunakan untuk menentukan faktor yang paling dominan terhadap kualitas botol kemasan 60 ml. Berdasarkan hasil analisis yang digunakan dalam penelitian ini, terlihat ada beberapa faktor yang mempengaruhi kualitas botol plastik kemasan 60 ml berikut : mesin, manusia, material, metode dan lingkungan.

The packaging is one of the industrial tasks in beverage an industry which is repetitive and monotonous with the same position throughout the day. In order to complete the packaging process, the workers do the tasks in sitting position during one work shift. Sitting position at work is commonly applied in both service and manufacturing industry. This position is mostly applied because it is considered to make a worker feel comfortable in finishing the task. Being supported by a comfortable physical work environment, a worker may sit in long hours during the workday. The aim of the study was to determine the level of productivity of the task done in the prolonged sitting position and affected by the work environment and level of fatigue. With software of SPPS 22 using analysis double correlation test, it was obtained that the value of Sig. F Change 0.027. The software analysis showed that the physical work environment and fatigue influenced packaging productivity significantly. R (the value of Pearson Correlation) obtained was 0.742 which means that there is a strong correlation between free variable (X) and bound variable (Y). R (the value of Pearson Correlation) obtained was 0.742 which means that there is strong correlation between free variable (X) and bound variable (Y).
