Lean Management and BPM, a strong combination for process improvements

Paper ID- AMA-04-09-2021-10682

At this time, many questions are asked about the best way to implement Lean Management effectively in a company. The Lean method, number one in the automotive world, an object of adaptation of the continuous processes to changes in customer demand or context. It is applicable to the information system. It has even become essential, since Lean improves the functioning of all the IT activities in which it has been tested, in particular BPM which helps structure the business processes of the company. Business Process Management (BPM) and Lean Management help companies streamline their business processes across applications and organizational boundaries. To more easily define how to transpose methods from the industrial world to BPM, it is therefore important to follow an effective implementation model and frameworks. To get there, in addition to the advanced tools that can: determine, develop, deploy, administer, manage and improve the process and skills, this article presents the implementation models and frameworks adapted to the situation of each business.

Applying PR current control in Parallel Active Filter for harmonic mitigation in the power distribution system

Paper ID- AMA-04-09-2021-10681

Current harmonics is one of the most common events that affect power quality in the distribution system. Parallel active filter (PAF) is the best solution to minimize harmonic distortion, but its effectiveness depends on how quickly and accurately its control algorithms can perform. In order to improve power system quality and mitigate the harmonics, this paper proposes the parallel active filter using a proportional resonant (PR) current control. Compared with PI controllers, the complexity of PR controllers is reduced considerably, combined with its good performance. Simulations were carried out using MATLAB/Simulink software to validate the performance of the PAF connected to a nonlinear load. The simulation results showed the effectiveness of proposed PR current control and the harmonic compensators to reduce the harmonics in the grid current. This reduction in harmonics is compliant to the IEEE 519 standard recommendations on harmonics levels.

Minimizing gearbox cost for Three-stage Bevel Helical Gearboxes

Paper ID- AMA-04-09-2021-10680

The current article aims to determine the optimum partial gear ratios of three-stage bevel helical gearboxes which can minimize the gearbox cost. Twelve main process parameters are adopted to examine their effects on u1 and u2. A plan of simulation experiment is conducted to serve for finding regression model. It is revealed that the total gearbox ratio parameter, ug, has the biggest effect on both response u1 and u2 when compared to those of others. Moreover, the predicted values given by regression model are significantly consisted of experiments.

IMPACT OF PROGRAM OF MECHANIZATION AGRICULTURE ASSISTANCE ON MAIZE COMMODITY PRODUCTION IN INDONESIA

Paper ID- AMA-03-09-2021-10679

Agricultural tools and machines (Mechanization) have an important and strategic role in achieving agricultural development goals in order to accelerate the achievement of national food self-sufficiency and the main strategic commodities in meeting the needs of food and animal feed. The problem is, not all maize production is of good quality according to animal feed and industry standards. This is what deserves attention, the quality of maize production increases so that it is able to meet domestic demand and opens up opportunities for export. For this reason, a study is needed to analyze the effectiveness of the use and utilization with an evaluation approach of the mechanization assistance program provided by farmers. The results of the study showed that 60% of maize farmers thought that the assistance was able to increase the production and productivity of agricultural products. The results of interviews with maize farmers showed that the estimated increase in maize production ranged from 20 - 40% from the previous one. Maize Shiller assistance is still not evenly distributed, even though this machinery is very helpful for farmers in overcoming post-harvest maize problems. The limited number of reliable technical personnel at the village level is a problem in itself. For this reason, the budget for increasing the number of maize Shillers, mentoring and training in the use of agricultural machinery needs to be increased, so that the distribution of agricultural machinery is evenly distributed and farmers who receive direct training can easily use mechanization on their own agricultural land.

Greenhouse gas sequestration in a microalgae culture with different nutrition regimes

Paper ID- AMA-03-09-2021-10678

A culture of the microalgae Scenedesmus sp. in a pilot closed raceway photo bioreactor (CRPB), with flue gas injection from a diesel engine was implemented. Two different nutritional medium, Z-8 and EPA were used to feed the culture growth that was monitored in terms of total and partial biomass productivity, carbon fixation and oil production during nine days. The system was sequentially sampled measuring the gas flow and concentration of the injected CO2, the amount of biomass harvested and the concentration of CO2 in the degassing flow. In addition, the pH was measured in the culture to assess the amount of CO2 instantaneously dissolved. The results at the steady state, showed a carbon fixation efficiency ranging between 21.6 % and 44.9 %, and that the Z-8 medium was clearly better than the EPA in terms of CO2 capture and therefore biomass and oil production. A continuous increasing of oil content in microalgae biomass up to 6.6 % dry basis, with maximum oil production rate of 2.27 g m-3d-1 was observed, with a maximum rate of biomass production of 44.97 g m-3d-1 and a maximum carbon capture rate of 2.27 g m-3d-1 was achieved with the culture medium Z-8.
