Abstract: This study examines the effect of intellectual capital, which includes human capital (VAHU), structural capital (STVA) and relational capital (VACA), on firm value (PBV), with financial performance (ROA) as the mediating variable. The population of this study consists of companies listed in the LQ45 index during the period 2020-2023. A total of 160 companies were selected as the sample using the purposive sampling method. The results show that human capital, structural capital and relational capital partially have a positive and significant effect on financial performance. Further tests show that structural capital has a positive and significant effect on firm value, while human and relational capital have a positive but insignificant effect. Financial performance mediates the relationship between human, structural and relational capital positively and significantly on firm value. In this research, the leverage variable (DER) and firm size are also used as control variables and the results obtained show that leverage has a positive and significant effect on firm value, while firm size has a negative effect on firm Keyword: Firm Value. Human Capital. Structural Capital. Relational Capital. Financial Performance. INTRODUCTION Companies that have go public will receive a general rating and be listed on the Indonesian Stock Exchange as a company categorized by stock indexes, one of which is LQ45 (Aristi & Supriyadi, 2019. Ismiati, 2020. Witjaksana et al. , 2. The LQ45 stock index is a stock index that ranks companies based on their liquidity value and considers market capitalization (Indrayana et al. , 2020. Rudianto, 2. The LQ45 index calculation is done by looking at the liquidity value index by taking the 45 companies that have the highest liquidity The Covid-19 pandemic that occurred resulted in the world economy, especially Indonesia, experiencing a decline due to preventing the spread of the Covid-19 virus. The entry of the Covid-19 virus pandemic in Indonesia was determined on March 31 2020 and became a national disaster on April 13 2020. The status of the Covid-19 pandemic ends on June 21 2023 1138 | P a g e https://dinastipub. org/DIJEFA Vol. No. 2, 2025 as determined by Presidential Decree . ttps://nasional. Preventing the spread of the Covid-19 virus was carried out by temporarily stopping company activities, but this had an impact on the company's financial performance which resulted in a decrease in the value of the company's shares in the LQ45 index. Changes in the share value of LQ45 index companies can be seen in Table 1. Table 1 LQ45 Composite Stock Price Index Table for 2019-2023. Source: Indonesian Stock Exchange . Since the onset of Covid-19 in 2020, the LQ45 index has experienced fluctuations, starting with a 3. 20% increase in 2019 due to the absence of the pandemicAos effects. However, in 2020, the index dropped significantly by 7. 80% as the impact of Covid-19 hit the market. Recovery efforts began in 2021, resulting in a smaller decline of 0. 4%, followed by slight growth of 0. 6% in 2022 and a significant rise of 3. 60% in 2023. These fluctuations reflect the performance of the 45 most liquid companies on the Indonesian Stock Exchange, whose share prices collectively influence the LQ45 index. Share prices on this index represent company value, which is shaped by investor perception of the company's market value, including its debt and capital. A high company value indicates strong management performance and boosts investor, supplier, and creditor confidence (Elfiswandi et al. , 2. Today's knowledge-based companies typically rely on science and technology to generate profits. Knowledge-based companies are companies that rely on the use of technology and human resource expertise to create superior products or services (Hodijah et al. , 2. intellectual capital . ntellectual capita. is a collection of knowledge assets related to a company that contributes to the company's competitive advantage and increases the company's value for the company stakeholder (Anggraeni & Indarti, 2. Widiatmoko et al. added that intellectual capital is an intangible asset, which is knowledge and information used to increase competitiveness and company performance. Indarti et al. , explains that disclosure of intellectual capital is very much needed by stakeholders in the formation or creation of company Disclosure of intellectual capital can increase transparency, minimize gaps regarding important company information, increase prices, and reduce costs of capital. The components of intellectual capital consist of: human capital, structural capital, as well as relational capital. Shulthoni & Rizkya . stated that human capital . uman capita. used to see the company's effectiveness in managing employee skills, knowledge and abilities in contributing to adding value to the company. The relationship between added value and employee expenses provides an illustration of the employee's ability to provide added value to the costs incurred by the company for employee needs (Aminda et al. , 2. Structural capital . tructural capita. is the ability of a company to meet operational costs and non-operational costs including employee salaries in optimizing intellectual performance by taking into account added value (Aminda et al. , 2. Hodijah et al. , added that the fulfillment of company routines in the form of industrial operations, manufacturing activities, organizational culture, and management philosophy is carried out to support employees in maximizing intellectual performance and maximizing overall business performance. Relational capital (Relational 1139 | P a g e https://dinastipub. org/DIJEFA Vol. No. 2, 2025 is a measurement of the added value of a company to determine the close relationship between the company and business relations (Hodijah et al. , 2. Shulthoni & Rizkya . , added that relational capital is used to see the extent to which business relationships can maintain cooperation with the company. Apart from that, the value of the company will increase if there are other factors as mediation or intermediaries. The mediator of company value in this research is financial performance. Financial performance is the achievement of a company based on the company's success in managing finances and business activities (Rahayu, 2. Profitability according to Fauziah et al. , is a ratio that functions as a measuring tool to measure the level of a company's ability to manage all funds and all other assets invested in generating profits. The grand theory underlying this research is Stakeholder Theory and Resource-Based Theory (RBT). Stakeholder Theory emphasizes that companies not only operate in the interests of shareholders, but also to meet the expectations and interests of various stakeholders, such as employees, suppliers, customers, government and society at large (Barney & Harrison, 2020. Freeman et al. , 2. This theory is relevant in the context of this research because company value is greatly influenced by how the company manages its intellectual capital and how information regarding financial performance is disclosed to stakeholders. When companies are able to increase transparency and provide accurate information regarding financial performance, this will increase the confidence of investors and other stakeholders, which will ultimately have an impact on increasing company value. Meanwhile. Resource-Based Theory (RBT) focuses on how companies gain competitive advantage through unique and difficult to imitate resources, including intellectual capital (Sony, 2019. Utami & Alamanos, 2022. Zhang et al. , 2. In this research, intellectual capital consisting of human capital, structural capital and relational capital is a valuable asset that can provide added value to the company if managed well. This theory asserts that companies that have rare and non-imitable resources will be able to create sustainable competitive advantages. Thus, effective intellectual capital management will improve financial performance, which in turn contributes to increasing company value. The combination of these two theories provides a strong conceptual basis in explaining how intellectual capital and financial performance interact in forming company value. Previous research related to this research, among others, was carried out by Shulthoni & Rizkya . , that relational capital influences company value because of research which is implemented value added capital employed (VACA) has a good impact on changes in company value, while structural capital and human capital have no influence on company value because they have no impact (Shulthoni & Rizkya, 2. In contrast to research results (Rabaya et al. , that intellectual capital consisting of human capital, structural capital and relational capital influences company value well (Subagio, 2. Research conducted by Hodijah et al. that relational capital has a good impact on change Return on Assets (ROA) which can be used as a measure of a company's financial performance, while structural capital and human capital have no impact on ROA which can be used as a measure of a company's financial performance. Further research conducted by AcuyaOpazo & Gonz alez . proves that intellectual capital can influence a company's financial Research on the influencing factors of company value using financial performance as an intermediary was carried out by Aminda et al. , results that financial performance cannot bridge intellectual capital and company value (Kumalasari et al. , 2. Another research conducted by Prakasa . , stated that intellectual capital can influence a company's financial performance using ROA and financial performance using ROA can influence company value, and intellectual capital which is moderated by financial performance using ROA can influence company value. However, intellectual capital itself cannot directly influence company value. 1140 | P a g e https://dinastipub. org/DIJEFA Vol. No. 2, 2025 Previous studies on the influence of intellectual capital on financial performance and firm value have shown inconsistent results, particularly regarding the direct or indirect effects through financial performance. This research addresses these gaps by analyzing the mediating role of financial performance in the relationship between intellectual capital comprising human capital (VAHU), structural capital (STVA), and relational capital (VACA) and firm value (PBV), specifically in LQ45 companies during the 2020Ae2023 period. The study introduces novelty by incorporating leverage (DER) and firm size as control variables to provide a more comprehensive understanding. Focusing on highly liquid and well-performing firms in the Indonesian capital market, this research offers valuable insights for corporate strategy and financial management, highlighting the importance of optimizing intellectual resources to enhance competitiveness, profitability, and firm value. METHOD The population in this study includes all companies listed on LQ45 of the Indonesia Stock Exchange (BEI) during the 2020-2023 period, with a total population of 180 companies. Sample selection was carried out using a purposive sampling method based on certain criteria, namely companies listed in Semesters 1 and 2 on the LQ45 index during the 2020-2023 period, companies that published financial reports during that period, as well as companies that did not have the data or negative ratios required in the research. Based on these criteria, a sample of 160 companies was obtained that met the requirements for further analysis. The hypothesis in this research consists of seven statements that test the influence of various variables on financial performance and company value. The first hypothesis (H. states that human capital has a positive effect on financial performance. The second hypothesis (H. states that structural capital has a positive effect on financial performance. The third hypothesis (H. proposes that relational capital has a positive effect on financial performance. The fourth hypothesis (H. states that human capital has a positive effect on company value. The fifth hypothesis (H. reveals that structural capital has a positive effect on firm value. The sixth hypothesis (H. proposes that relational capital has a positive effect on firm value. The seventh hypothesis (H. states that financial performance has a positive effect on company value.

For Regression Equation 2, the skewness and kurtosis are 7. 071 and From this data, the skewness and kurtosis values are not between -2 to 2, so the data is not normally distributed. To overcome this, data transformation is carried out so that the data is transformed normally. The results of the normality test after data transformation are as 1142 | P a g e https://dinastipub. org/DIJEFA Vol. No. 2, 2025 Table 4 Normality Test Table Skewness Kurtosis Model Statistic Results Statistic Results Regression Equation 1 Regression Equation 2 Source: SPPS, processed by researchers In Table 5 above, in Regression Equation 1, it can be seen that the statistical value of skewness is 0. 373 with a standard error of 0. 192, resulting in a result of 1. 946 and the statistical value of kurtosis is 0. 743 with a standard error of 0. 381, resulting in a result of 1. Thus. Regression Equation 1 is said to be normally distributed. In Regression Equation 2, it can be seen that the statistical comparison value of skewness and standard error, which respectively have a value of -0. 227 and 0. 192, is -1. The kurtosis value is -0. 038 which is obtained from a statistical comparison of -0. 015 with a standard error of 0. 381 which is between -2 to 2 so it is said to have a normal distribution. Classical Assumption Test Multicollinearity Test This test is carried out to find out whether in the regression model there is a correlation between the independent variables. If the tolerance value is < 0. 1 with a VIP value > 10, then the model is said to be free from multicollinearity.

This indicates that financial performance can mediate human capital, structural capital and relational capital on company value. Intellectual capital increasing company value through financial performance. Discussion Human capital has a positive and significant impact on financial performance, supporting the first hypothesis. This finding aligns with studies by Putri & Nurfauziah . Zunariski et al. , and Sika & Astini . , which highlight the strategic role of human resource management in enhancing financial outcomes, as measured by ROA. According to 1150 | P a g e https://dinastipub. org/DIJEFA Vol. No. 2, 2025 Resource-Based Theory, human capital is a valuable, rare, and hard-to-imitate asset, while stakeholder theory emphasizes that HR management should also address the needs of various Incorporating human capital into corporate strategy not only boosts financial performance but also strengthens stakeholder relationships. Similarly, structural capital positively and significantly influences financial performance, supporting the second hypothesis. Effective management of structural capital enhances productivity and cost control, as confirmed by prior research from Putri & Nurfauziah . Zunariski et al. , and Herlina et al. Relational capital has a positive and significant effect on financial performance and the third hypothesis is accepted. The company's ability to collaborate with customers stakeholder proven to create trust in the company. All interested parties will not hesitate to help the company in carrying out its operations. These results are in line with research conducted by Hodijah et . Putri & Nurfauziah, 2. Zunariski et al. Ratnadi et al. Herlina et . , and Ika & Astini . which show that relational capital relationships can have a positive impact on financial performance. Human capital has a positive and insignificant effect on firm value and the fourth hypothesis is rejected. The effectiveness of human resource (HR) management in an organization is demonstrated by knowledge of how to optimize employee performance to produce added value for the company. The right HR management strategy can increase productivity, operational efficiency and sustainable innovation, although individual or team contributions may not always have a direct impact on company value. Companies can create a work environment that supports employee growth by providing relevant training programs, a clear performance management system, and a positive work culture, work-life balance, and appropriate incentives. Therefore, effective management will increase the competitiveness and sustainability of the company in the long term, although the impact of HR on company value may not be visible in the short term. Research conducted by Padila & Muslimin . Mardiana et al. , as well as Nasution & Ovami, . which prove that intellectual capital can positively influence company value are rejected.
