Different features of work systems in Indonesia and their consequent approaches.

Indonesia, with its ultimate development goal of "developing the people and the community as a whole," in fact is facing problems in the execution of this goal. With a population of more than 200 million persons, different in sociocultural background, educational level and environmental conditions, it is understandable that the process and results of technological choices and transfers for various target groups will be different. A wide range of work systems is found, from the simplest man-tool system to the most complex. The conditions are becoming even more complex, a phenomenon especially evident through studies of their sociocultural, psychological, and environmental factors. As a consequence, if success is to be gained in anticipating and understanding the role of Indonesia in the global competition that lies ahead, a very wise approach to the situation by using local values that are often based on traditional habits and customs in a modern context should be carried out. This approach will require an immense amount of time, dedication and effort. Improvement endeavors that have been carried out in different work systems in different types of activities and industries, showed that if the improvement to be sustained, a holistic, systemic, and interdisciplined participatory approach should be taken into consideration where the technical, economical, ergonomic, sociocultural, energy, and environmental factors will play significant roles.

Balinese dance exercises improve the maximum aerobic capacity.

The maximum aerobic capacity can be used to predict the maximum working capacity. The maximum working capacity plays an important role in achieving the best performance. Therefore, physical fitness program for maintaining maximum working capacity is a must. A study on the application of Balinese dance exercise was carried out. Sixty young male Balinese, aged from 17 to 19 years were used as subjects. They were divided into two groups: Experimental group (EG) and control group (CG) based on their VO2max. The EG participated in a program of Balinese dance exercise 3 x 50 min per week for 8 weeks. Pretest-posttest control group design was applied. The maximum aerobic capacity was measured, based on the Modified Harvard Step-up Test and nomogram of Astrand. The results are as follows: there is a very significant improvement of VO2max from 2.7 +/- 0.5 l/min or 51.1 +/- 9.1 ml/kg/min into 3.1 +/- 0.5 l/min or 58.9 +/- 9.8 ml/kg/min. Other parameters such as resting heart rate, blood pressure and percent body fat were decreased significantly. The study concludes that Balinese dance exercise could be used as a program for physical fitness maintenance.

Improvement of working posture increases productivity of roof tile home industry workers at Darmasaba Village, Badung Regency.

In the production process of the roof tile home industry in Darmasaba Village, Badung Regency, bad working postures such as bending and squatting positions were observed. It caused an inefficient low speed of work as a consequence. Therefore, an intervention study in forms of a demo-plot was carried out, introducing the correct working posture and working method. The process of plating clay material is done on the desk in a standing position and can be performed continuously, without waiting for any other works. By so doing, it was found that productivity of workers increased 20% per day.

Introducing ergonomics through "subak" organization among the farmers in Bali.

Due to a shortage of owned land, it is impossible for Balinese farmers to adopt fully mechanized tools or techniques. Therefore, the use of handtools for agricultural work is still the only alternative. The ergonomical evaluation of local farmers' handtools is becoming so important. An intensive study was conducted in Bongan Village of Tabanan. The study was focused on the agricultural work cycle and the handtools used. The observation technique was completed by interview and measurement. The results are as follows: 1) all farmers in Bongan village are members of "subak" (water organization group); 2) any activity regarding agricultural work must be in accordance with what has been set forth by the "subak"; 3) the handtools used are hoe, plough, sickle, long knife, herb cleaner and local thresher; 4) pattern of crop planted per year are paddy-paddy-crop; 5) some improvements on handtools used have been done, but some are still not ergonomically sound. To anticipate the result No. 5, ergonomics intervention have been done, such as awareness program, informal workshop and showing good examples of ergonomics tools. From the immediate results, it could be concluded that farmers in Bongan Village are well responsive to the ergonomics information and its advantages.

Ergonomics productivity enhancement at government-owned sugar cane factories in east Java, Indonesia.

To cope, both with the increasing demand for sugar and to win the global competition as well, government-owned sugar cane limited number xxi-xxii, has decided to enhance its productivity, among other things, by implementing ergonomics principles within their factories. In the execution, ergonomics application have been carried out since 1992, which resulted in safer, healthier, and more efficient working conditions and environment. Some of the improvements yielded economic gains through higher productivity via increased output, lower cost, faster processing, etc. Improvements related to cane transloading and unloading processes resulted in a higher amount of cane being transferred from the trucks to the lorries as well as from the lorries to the cane table. Fewer clinical visits, lower health care costs, more efficient inspection, and fewer fatigue complaints are also achieved by improvement steps, which increase the productivity as end results. With all those economic gains, full and long lasting management's concern and commitment could be created without a doubt.

The effect of modern Balinese Baris dancing exercise (MBBDE) on serum lipid profiles.

There is still a lack of information on the effect of regular dancing exercise on lipid profiles. On the other hand, many studies have been carried out on the effect of aerobic exercise on lipid profiles. This study tried to find out the effects of Modern Balinese Baris Dancing Exercise (MBBDE) on serum lipid profiles. Subjects of the study were 30 healthy young male Balinese as an experimental group, and another 30 healthy young Balinese as control group. The MBBDE involved exercise intensity at 70-80% of targeted heart rate, for 50 min period, 3 times per week for 8 weeks. Pre- and post-control group design was applied. Total cholesterol and triglyceride were measured enzymatically. Following MBBDE 3 x 50 min/week for 8 weeks duration, serum level of high density lipoprotein cholesterol (HDL-C) concentration increased significantly from 55.3 +/- 2.32 mg/dl to 63.2 +/- 2.82 mg/dl (p < 0.001). It was also associated with the decrease of total cholesterol concentration from 195.5 +/- 21.10 mg/dl to 161.8 +/- 21.29 mg/dl (p < 0.001); triglyceride concentration from 132.2 +/- 9.65 mg/dl to 110.6 +/- 9.08 mg/dl (p < 0.001); and low density lipoprotein cholesterol (LDL-C) concentration from 113.8 +/- 21.68 mg/dl to 76.9 +/- 20.76 mg/dl (p < 0.001). No significant differences were found in the above parameters in the control group. It is concluded that MBBDE is an aerobic, endurance exercise, and therefore produces beneficial effect on the serum lipid profiles.

Problems of ergonomics in Bali, Indonesia.

Development in Indonesia, particularly in Bali, has been planned and done through several stages of the Five-Year Development Programs, which started in 1969, and emphasized intensification of agriculture and extensification of industries related to potential resources available in the region. In the process, industrialization, being regarded as a prerequisite to higher living standards, brought with it problems concerning safety, health, and work conditions, especially with respect to transfer of technology. As examples, experiences and data, related particularly to ergonomics in the sectors of agriculture, hotel business, textile mills, transportation, and others in Bali, Indonesia, are reported. In dealing with such possible consequences of development, efforts to find fundamental solutions should be given the highest priority. It is necessary to make use of all the existing institutions having potential functions and roles in the policy of development planning, and to take into consideration the factors of safety, health, and work conditions in specifying technical and financial development projects for industrialization.
