The best quality of services provided by health care facilities can be realized if medical devices are in a reliable and safe condition. A large number of medical devices and the use of various types of medical devices have been a problem for hospital management to decide the level of priority in carrying out medical equipment maintenance. The purpose of the maintenance is to increase their availability and to reduce maintenance costs. This study aims to show how to determine the priority level of medical device maintenance based on the calculation of the criticality scores of medical devices. The criticality scores are obtained based on the assessment of criteria, sub-criteria, and grade by using the method of Analytical Hierarchy Process (AHP). The devices with higher critical weight take higher priority for maintenance than devices with lower critical weight. The approach was applied for 20 medical devices at the Out Patient Department of Eye Hospital in Jakarta to describe how to prioritize the maintenance of medical devices.

PT. XYZ is a manufacturing company that produces Crude Palm Oil (CPO). The competition Crude Palm Oil (CPO) company do not only happen in manufacturing companies but also among supply chain components. Due to the increase of fierce competition, it is necessary to improve companies' value chain that may increase productivity and reduce costs. The purpose of this study was to analyze the supply chain and value chain of CPO in some companies. Data were analyzed using both qualitative and quantitative analysis within descriptive research. This research was started by conducting a supply chain analysis and followed by a value chain analysis and ended with an improvement of the value chain. The qualitative analysis describes supply chain and value chain while the quantitative analysis is used to find out value-added values and establishment of the value chain. Based on the analysis, the value chain of CPO in the company consists of four main participants: suppliers of raw materials (plantation), processing plant, distributor, and customer. In this research, the analysis was focused on two participants: palm oil plantation and palm oil processing plant. The oil palm plantation activities include nurseries, planting, plant maintenance, harvesting, and shipping while the processing plant consists of reception, sterilizing, threshing, pressing, and classification. The company's value-added actual condition in oil palm plantation was 72.42% and palm oil processing plant was 10.13%. A low-cost strategy had been applied, resulting in the value-added increasing of oil palm plantations by 1.08% and at processing plants by 11.73%. The increase in value-added has been able to reduce the company's costs. However, this study still has limitations because the analysis only covers plantation and processing plant value chain; the company's distribution and consumers of CPO products for maximizing the value-added of a CPO value chain have not yet been studied.

Purpose The purpose of this paper is to develop and optimize a mathematical model based on a framework that integrates key concepts related to a circular economy (CE) and sharing economy (SE) for a leading manufacturer of laptops in India. Design/methodology/approach This study mathematically modelled the integration of sharing networks in a circular production system. This is done through an optimization package that deploys a multi-objective mixed-integer linear programming model. Findings This study evaluated the economic benefit and the environmental impact associated with the aforementioned integration in a production system. This study illustrated the inverse relationship between economic benefit and environmental impact and provided a set of solutions that can be used according to the case organizations goals, capacities and logistical capabilities. Research limitations/implications This study will aid similarly structured companies in adopting this approach to integrate sustainable practices in their production system. It also enumerated Industry 4.0 (I4.0) use-cases that can be used to effectively implement this mathematical model. Further research can be conducted using multiple companies in an inter-dependent network to maximize synergy. Practical implications This study will help to better understand the role of sharing networks in the circular economy model especially in the consumer electronics industry. Originality/value This study is the first of its kind to mathematically model the integration of aspects related to SE and CE.

High levels of crude fiber contained in tofu waste become a limiting factor for its use as a source of feed. The purpose of this research is to improve the quality of tofu waste as a source of feed through the ensilage process using the Bacillus amyloliquefaciens bacteria. The design used was the Factorial Complete Random Design with two treatments, i.e. the Bacillus amyloliquefaciens concentration and fermentation time. This research used three Bacillus amyloliquefaciens concentrations, i.e. 5 %, 10 %, and 15 %, and six fermentation times, i.e. 2 days, 3 days, 4 days, 5 days, 6 days, and 7 days. Based on the analysis of variance, the treatment of Bacillus amyloliquefaciens concentration and fermentation time and their interaction had an effect on the level of crude fiber and the total silage acid of tofu waste (P<0.01), but did not have an effect on its water level (P>0.05). The greater the dose of Bacillus amyloliquefaciens inoculated on the tofu waste, the smaller the average value of its crude fiber; contrary to the total lactic acid produced. The best treatment was obtained at doses of Bacillus amyloliquefaciens of 15 % fermented for 5 days with an average of crude fiber level of 17.3 % and total acid average of 0.87 %, which means they meet the requirements of SNI (Indonesian National Standard) for the ideal total acid criteria, i.e. 0.5-2.0 %. A decline in the level of silage crude fiber of tofu waste reached 44 % compared to tofu waste raw material. Based on the organoleptic test, the silage resulting from the fermentation of Bacillus amyloliquefaciens with a 15 % dose had the best aroma, color and texture compared to doses of 5 % and 10 %.
