ANALYSIS OF THE PHYSICAL WORKLOAD OF SUGARCANE HARVEST WORKERS AS THE BASIS FOR DETERMINING THE LENGTH OF REST BREAK AT BONE ARASOE SUGAR FACTORY
Full text linkArasoe Bone Sugar Factory is one of the sugar factories in Bone Regency, South Sulawesi. The production process at this company entirely uses machines that run automatically. However, the sugarcane harvesting activity is still carried out manually. All sugarcane harvesting activities result in physical workload on workers, especially when lifting sugarcane since in one loading, the workers are able to lift more than 30 kg of sugarcane. This activity is carried out repeatedly which results in fatigue on the harvest workers. The other factors that affect fatigue on the harvest workers are the harvested sugarcane plantations that can reach approximately 7 hectares in area and the work that lasts for 7 hours each day. This study aims to determine how much physical workload is experienced by sugarcane harvest workers and to determine how long the rest break is based on the physical workload that is obtained while working for the sugarcane harvest workers. The assessment of physical workload was carried out using the Cardiovascular Load (%CVL) method and the calculation of the length of rest break was carried out using a physiological approach. Based on the results of calculating the percentage of Cardiovascular Load (%CVL), it was discovered that all respondents experienced fatigue consisting of 5 workers with a %CVL of 60%, 13 people with %CVL of 80%, and 2 people with %CVL of 100%. Therefore, all respondents were included into the category of heavy physical workload. The optimal rest break is 80.79 minutes, while the rest break given is only 60 minutes. Hence, an additional 20.79 minutes of rest break is needed. The rest break of 20.79 minutes is used for spontaneous breaks, i.e., short break after the workload

Full text linkAbstractThe potential amount of coconut sawdust biomass in Indonesia is very abundant, so far it has not been utilized optimally and tends to be wasted as waste. Coconut sawdust with the main composition of carbon contains heat equivalent to light coal, which is around 4400 kcal/kg. Even though its calorific value is still low, it has the potential to be used as a solid fuel source or an alternative energy source. The calorific value of coconut sawdust can be increased through the pyrolysis process. A study has been carried out on the effect of nitrogen inert gas flowing continuously into the pyrolysis reactor of coconut sawdust biomass waste (Cocos nucifera) on the calorific value of the resulting charcoal. The aim of the research is to determine the effect and optimum flow path of nitrogen inert gas which gives the maximum calorific value of charcoal product. From this study it was concluded that the continuous flow of inert nitrogen gas into the pyrolysis reactor had an effect on increasing the calorific value of the charcoal product by up to 4% compared to not using the inert gas. The optimum nitrogen gas flow rate is 2 L/minute giving a maximum effective calorific value of 7200 kcal/kg AbstractThe potential amount of coconut sawdust biomass in Indonesia is very abundant, so far it has not been utilized optimally and tends to be wasted as waste.

ANALYSIS OF PRODUCTION CYCLE ACTIVITIES ON THE ASM-AS CABLE PROJECT USING MANUFACTURING CYCLE EFFICIENCY IN THE WIRE HARNESS INDUSTRY
Full text linkPT ABC is a company that produces various types of wire harnesses to produce cable assemblies. Wire harnesses are used in a wide variety of electronic products, such as motor vehicles, airplanes, industrial machines and household appliances. In this study the product that will be the object of this research is the wire harness assembly PN 03230462-0101 which is included in the ASM-AS cable project which has a long assembling lead time, this is because this PN is composed of several small PNs, namely PN 03218291- 01, 03218572- 01, 03218569-01, 03222900-01, 03218576-01, 03218574-01, 03223128-01, 03230390-01, 03230391-01. Small PN must be assembled first, so the time required will be longer and the process is quite complicated, there is still no clear work instruction in the cable assembly process, another problem is production efficiency which is still lacking based on company data from each each operator's actual production line that works is greater than the allocation of operators that should be. So that conditions like this cause a decrease in productivity and profits earned by the company. Project cable ASM-AS PN 03230462-0101 is one of the processes that will be improved using a manufacturing cycle efficiency approach. The number of value-added activities is 2,384 seconds, while non-value-added activities are 2,565 seconds, impacting productivity and MCE by 48%.
