Pelaksanaan Perjanjian Pembayaran Upah Kerja Menurut Undang-undang Nomor 13 Tahun 2003 Tentang Ketenagakerjaan Pada PT. Natura Mega Murni Di Pekanbaru
No full textWork agreements are the beginning of the birth of industrial relations between employers and workers. With the development of the business world that is very dependent on the existence of good industrial relations, because of the better industrial relations it will have a huge impact on the development of the business world. One of the reasons for good and maintained industrial relations is the need for legal protection and certainty, especially for workers, with the employment agreement expected by employers not to be arbitrary in paying wages without considering the economy of workers and their families. The problems found in writing this thesis are how the implementation of payment of work wages at PT. Mega Murni Natura in Pekanbaru, as well as how to supervise the Riau Provincial Manpower Office against the implementation of work wage payments based on Law Number 13 of 2003 concerning Labor. In this study the type of research used observational reasearch with the nature of descriptive research. The research location chosen by the author is PT. Natura Mega Murni in Pekanbaru because of weaknesses in the payment of wages. The population in this study is the leader of PT. Natura Mega Murni and the Manpower Office with a sample of 36 respondents who were leaders and workers and 1 respondent was the Head of the Transmigration Manpower Office in Riau Province. Primary data is obtained directly from the field where the author directly takes to the field in order to obtain the required data while the secondary data comes from literature books relating to the problem of the author. Data collection tools used were interviews and questionnaires. The data obtained are then analyzed in a descriptive manner which is then drawn conclusions by the method of inductive conclusions. The results of the study obtained that the implementation of payment of work wages at PT. Natura Mega Murni in Pekanbaru where workers still receive wages that are not in accordance with the minimum wage set by the Pekanbaru city government and there are still many workers who do not understand the work agreement. Supervision by the Riau Provincial Manpower Office on the implementation of payment of labor wages is still not maximal and there is a lack of guidance and socialization for companies and workers, so there are still many companies that commit violations related to the payment of labor wages and the maximum employment of Riau Province to companies companies that commit violations related to labor wages
AVOA and ALO Algorithm for Energy-Efficient No-Idle Permutation Flow Shop Scheduling Problem: A Comparison Study
No full textGlobal energy consumption is a pressing issue and is predicted to continue increasing between 2010 and 2040. Among the various sectors, the industrial sector, particularly manufacturing, is the main driver of this increase. To effectively address this growing problem and support energy conservation efforts, reducing idle time on production-related machines is critical. The No-Idle Permutation Flow Shop Problem (NIPFSP) and, indirectly, the need to reduce energy consumption in manufacturing processes are the driving forces behind this study. The African Vultures Optimization Algorithm (AVOA) and the Ant Lion Optimizer (ALO) are two novel meta-heuristic algorithms designed to achieve this goal. The effectiveness of both AVOA and ALO was rigorously evaluated across three distinct scenarios: small, medium, and large. Statistical analysis, in the form of independent sample t-tests, was employed to compare the performance of these algorithms. We found that, while both algorithms yielded similar results in the small case, AVOA demonstrated a superior capability in optimizing the NIPFSP in the medium and large cases and, consequently, in curbing energy consumption. This implies that AVOA offers a more promising approach to addressing energy consumption concerns in the manufacturing sector, particularly in scenarios involving medium- to large-scale production processes. The implementation of such innovative meta-heuristic algorithms holds the potential to significantly contribute to global energy conservation efforts while enhancing the efficiency of industrial operations
Energy-efficient No-idle Flowshop Scheduling Optimization Using African Vultures Algorithm
No full textThe issue of energy consumption is currently a major concern globally, especially in the industrial sector, where most of the energy demand comes from the manufacturing sector. To reduce energy consumption, one of the proposed strategies is to reduce the idle time between jobs on machines during the production process, known as No-Idle Permutation Flowshop Scheduling (NIPFSP). This research proposes the application of the African Vultures Optimization Algorithm (AVOA) as a solution to the energy consumption challenge in the case of production scheduling. The algorithm is examined in detail through a series of trials to obtain the most efficient work order in the production schedule, subject to careful setting of iteration and population parameters. The result of implementing the AVOA algorithm is then compared with the method used by the company in a scheduling case. The research findings show that AVOA significantly outperforms the method commonly used by the company, confirming its performance advantage in optimizing energy consumption in the context of production scheduling
