Class i Okaba UPBU employees. Merauke Regency, also lack the will to work to be better every day and lack enthusiasm and enthusiasm in working, which is why these problems still occur to this day. Class i Okaba UPBU employees. Merauke Regency, are unable to work together with their fellow co-workers because employees lack character as role models, motivators, and enablers. Problems in leadership are reviewed based on the opinion of Mintzberg . , namely interpersonal, informational, and decision-making. Leadership is a way for a leader to influence the behaviour of subordinates so they want to work together and work productively to achieve organisational goals (Hasibuan, 2. A good leader can provide support to his subordinates, and this support is one of the factors that can affect employee performance. This is according to Mathis and Jackson . In this study, the performance of UPBU class i Okaba employees. Merauke Regency, was indicated to be influenced by the leadership found in UPBU class i Okaba. Merauke Regency. Simanjuntak . stated that company performance and everyone's performance also depended heavily on the ability of its leaders to regulate work systems and to arouse subordinates to work more enthusiastically by developing worker competencies, as well as motivating all employees to work This is supported by research from Wahyuni . , which found that leadership has a positive and significant effect on employee performance. Then. Rayuddin et al. found that leadership has a positive and significant effect on employee performance. In addition to problems in leadership, problems were found in the work environment. Hasibuan and Bahri . found that the work environment has a positive and significant effect on employee performance, and Idris and Ngatno . found that the work environment has a positive and significant effect on employee performance. In addition. Moulana et al. found that the work environment has a positive and significant effect on employee performance. The phenomenon of the work environment is reviewed through the opinion of Sedarmayanti . , including the physical and non-physical environment. In its physical environment. Class i Okaba UPBU. Merauke Regency has an inadequate workspace, such as poor internet connection, buildings that look dull, and office equipment that is not fully The work environment can affect an employee's performance because a human being will be able to carry out activities properly, so an optimal result is achieved if an appropriate environmental condition is shown. The work environment has the meaning of all the tools and materials encountered, the surrounding environment in which a person works, his work methods, and good work arrangements as individuals and as a group. Environmental conditions are said to be good or appropriate if humans can carry out their activities optimally, heal healthily and be comfortable. An unfavourable environment can demand more effort and time and does not support obtaining an efficient system design (Sedarmayanti, 2. The leadership conditions and work environment that have been described make the work motivation of class i Okaba UPBU employees. Merauke Regency, not high This is in accordance with the opinion of Sutrisno . , which states that the external factors that influence employee motivation are leadership and the work Mangkunegara . suggests that motivation is moving employees J - B O M . VOL 1 . : 109 Ae 128, 2022 EFFECT OF LEADERSHIP AND WORK ENVIRONMENT ON EMPLOYEE PERFORMANCE | 111 to be able to achieve the goals of their motives. In this study, work motivation is supported by research from Hasibuan and Bahri . , who found that work motivation has a positive and significant effect on employee performance. Work motivation is reviewed using the opinion of Kadarisman . , namely needs, drivers, and goals. This problem of work motivation is related to the condition of employees' sense of security in their work which is not sufficiently conditioned optimally where the location of class i Okaba UPBU. Merauke Regency is far from urban areas. Literature Review Leadership Leadership is a way for a leader to influence the behaviour of subordinates so they want to work together and work productively to achieve organisational goals (Hasibuan, 2. Then. Robbins and Judge . stated that leadership is the ability to influence a group towards achieving a vision or a set of goals. This opinion is supported by the opinion of McShane and Von Glinow . , who states that leadership is about influencing, motivating, and enabling others to contribute to the effectiveness and success of the organisation in which they are members. Work Environment Sedarmayanti . states that the work environment is all the tools and materials encountered, the surrounding environment in which a person works, work methods, and work arrangements both as individuals and as a group. Kegan in Fraser . , genetically, each individual has the ability to adapt to the environment with certain patterns of behaviour to deal with environmental However, the formation of a work environment that supports work productivity will lead to job satisfaction for workers in an organisation. Work Motivation Motivation is encouragement from within as a reason underlying enthusiasm for doing something, directing behaviour that companies or organisations need human resources who have high motivation in order to provide good performance and enthusiasm to achieve high work performance. According to Kadarisman . , motivation as a driver or driver of behaviour towards achieving goals is a cycle consisting of three elements, namely needs, drives, and goals. Employee Performance Performance, according to Mahmudi . , is a multidimensional construct that includes many influencing factors. Meanwhile, according to Mathis and Jackson . , it is the work that has been achieved by employees in carrying out their The indicators are quantity, quality, reliability, presence, and ability to According to Mahsun . , performance is a description of the level of achievement of the implementation of an activity or program or policy, realising the goals, objectives, mission and vision of the organisation contained in the strategic planning of an organisation.
