INTRODUCTION
In the midst of the Covid-19 pandemic, economic growth in various business sectors in the world experienced a significant decline, causing a decrease in income for a country in general and business actors in particular (J. Abbas et al., 2021;Cusinato et al., 2020;Tohidast et al., 2020). The Covid-19 pandemic has resulted in recessions for several countries and significant changes in state policies in various sectors (Abdel-Hameed et al., 2021;Sumandiyar et al., 2021). There has been a decline in exports and imports, restrictions on entering a country, restrictions on access in the country, the implementation of WFH (Work from Home), many layoffs, and salary cuts by companies are major challenges in strategic business development (Hao et al., 2020;Supadiyanto, 2020). One of the business sectors that have felt the impact of the pandemic in Indonesia is the palm oil industry. The COVID-19 pandemic has had a negative impact on the Indonesian economy (Paramita & Putra, 2020;Sudiartini et al., 2020). However, the palm oil sector still shows resilience and contributes higher foreign exchange earnings compared to 2019. Indonesian palm oil is a global commodity and is able to compete with vegetable oils. The palm oil sector can become a mainstay as a driving force for the economy in the era of the COVID-19 pandemic. This provides a breath of fresh air for employees working in this sector.
PT Sinar Gunung Sawit Raya is a private company located in Masnauli Village, Sirandorung District, Central Tapanuli Regency, North Sumatra Province. This company is engaged in the processing of palm oil which is processed in a factory to produce Crude Palm Oil (CPO). The Covid-19 pandemic has not had much of an impact on the incomes of employees who work for this company because the palm oil industry is still able to compete. The results of the researchers' initial observations through data on FFB production in December 2020 of 5,552,640 kg did not reach the FFB production target (Gross) or decreased by 3.78% from the previous month of 5,762,529 kg so that the decrease last month from the RKAP was 91.63%. This indicates a decline in employee performance at PT Sinar Gunung Sawit Raya. The decline in employee performance may be influenced by several factors such as leadership style, communication, and work discipline. The results showed that leadership style, motivation, and work discipline positively and significantly affected employee performance (Abdelwahed et al., 2022;Dey et al., 2022). Previous research also shows that hypothesis testing Leadership style, motivation, and work discipline have a positive and significant effect on employee performance at PT Jago Diesel Surabaya (Nisyak & Triyonowati, 2016). It can be concluded that leadership has a direct positive effect.
A good leadership style can reflect a manager's level of responsibility towards his employees (M. Abbas & Ali, 2021;Stremersch et al., 2021). When employees are shown good leadership from their superiors, they can be encouraged to apply occupational health and safety in a disciplined manner. Therefore, leaders are expected to set the right example for their co-workers and employees (AlNuaimi et al., 2021;Padauleng et al., 2020). Leadership style is a set of strategies that leaders use to influence their employees to achieve company goals (Jamali et al., 2022;Leigh et al., 2021). Alternatively, a leadership style is a pattern of strategies or behaviors that leaders like and commonly use. In essence, the ideal leader is someone who can solve complex problems with existing creativity (Abu Nasra & Arar, 2020; Sahara, 2020). Transformed leaders are leaders who inspire, have creative solutions, and meet the needs of the organization. A good leader does not solve personal problems but seeks to help others succeed in their work.
One of the success or failure of a company is determined by many things, one of which is the leadership style applied in the company (Bintara et al., 2021;Ozturk & Ozcan, 2020). Leadership style is used as the ability to influence employees towards achieving goals (Elpisah & Hartini, 2019;Supriyati & Wijono, 2021). It is known that at PT SGSR the leadership style applied by the leader is less effective, where in the observations of researchers there are leaders who behave too firmly towards employees so that employees feel afraid to carry out their duties or meet with leaders. In addition, communication in this company also affects performance. Communication as sending and receiving messages or news between two or more people, or between organizations, so that the message in question can be understood and received clearly (Chu et al., 2020;Reilly & Hynan, 2014;Tsani et al., 2019). the initial observations of researchers in the field, it was seen that leaders and employees experienced communication problems that allowed the delivery of orders and information not to go well (Teguh & Ciawati, 2020;Zheng et al., 2018). Likewise, communication between employees is less effective when working in carrying out their duties so that work is sometimes not completed properly.
Besides communication, work discipline also has an impact on employee performance (Firmansyah et al., 2020;Hidayah & Santoso, 2020). Work discipline is the awareness and willingness of employees to obey all organizational regulations and applicable social norms (Suyanto, 2018;Yuliandi & Tahir, 2019). Thus, work discipline is a tool used by leaders to communicate with employees so that they are willing to change their behavior following the rules of the game that are applied (Hidayati et al., 2019;Hu & Liu, 2020). Preliminary data shows that absenteeism has decreased, there are employees who are late for morning apples and come to work, cut the rest hours that have been determined from the start, and there are still employees who are absent during working hours and violate the regulations that apply to the PT Sinar Gunung Sawit Raya factory. The purpose of this study was to determine and analyze the effect of Leadership Style, Communication, and Work Discipline on Employee Performance at PT Sinar Gunung Sawit Raya.

It proves that leadership style is one of the factors in developing employee performance in the company (Padauleng et al., 2020;Stremersch et al., 2021). From the research, the rise and fall of employee performance at PT Sinar Gunung Sawit Raya is influenced by the leader's style towards his subordinates at work. In this condition, the better the leadership style in leading the company's employees and having a high responsibility to their subordinates, the higher the employee's performance (Abu Nasra & Arar, 2020; Sahara, 2020). The study's results are also in line with previous research, which states that leadership style positively affects employee performance (Bintara et al., 2021;Wakhidah et al., 2021). It is in line with the theory that leadership is the ability to influence subordinates through communication either directly or indirectly (Ratna, A., Natajaya & Dantes, 2019;Sieweke & Santoni, 2020). Directly intends to move people to understand, be aware, and be willing to follow the leader's will. Thus the results of this study further strengthen previous studies and the theory that shows that the influence of leadership style has a significant effect on employee performance.

It proves that work discipline is one of the factors in developing employee performance (Hidayah & Santoso, 2020;Hidayati et al., 2019). From the research, the decline in employee performance at PT Sinar Gunung Sawit Raya is influenced by employees' lack of discipline and awareness in carrying out applicable regulations.

The study's results are also in line with previous research, which states that work discipline positively affects employee performance (Herman & Didin, 2020;Hidayah & Santoso, 2020). It is in line with the theory that discipline is a person's awareness and willingness to comply with all company rules and norms (Firmansyah et al., 2020;Yuliandi & Tahir, 2019). Thus the results of this study further strengthen previous studies and the theory that shows that the influence of work discipline has a significant effect on employee performance. Suggestions for PT Sinar Gunung Sawit Raya so that the research results can be considered in making related policies influencing employee performance.
