Abstract

Domestic wastewater serves as a habitat for various microorganisms, including coliform bacteria. High concentrations of total coliform exceeding the established wastewater quality standards indicate the presence of pathogenic contaminants that may contribute to the spread of waterborne diseases. This study aimed to determine the total coliform bacteria present in domestic wastewater in Makassar City. The method used was microscopic examination employing the Most Probable Number (MPN) method. The results of the MPN test showed that out of 50 domestic wastewater samples analyzed, 29 samples (58%) met the wastewater quality standards, while 21 samples (42%) did not meet the established standards. The samples analyzed were collected from various sources of domestic wastewater, including hotels, hospitals, factories, and shopping centers distributed across Makassar City

Abstract

The oil and gas sector is a strategic sector that plays an important role in supporting the Indonesian economy, but during the 2020–2024 period, this sector experienced stock price fluctuations that were not in line with the company's financial performance. This problem prompted this study, which aims to analyze the effect of liquidity and profitability on stock prices in oil and gas sub-sector companies listed on the Indonesia Stock Exchange (IDX) for the 2020–2024 period. This study uses a quantitative approach with multiple linear regression methods and secondary data in the form of annual financial reports from 12 oil and gas sub-sector companies obtained through the official IDX website using a purposive sampling technique. The results of the study indicate that the liquidity variable as measured by the Current Ratio (CR) and profitability as measured by the Net Profit Margin (NPM) do not have a significant effect either partially or simultaneously on stock prices. The coefficient of determination (R²) value of 1.8% indicates that stock price variations are more influenced by external factors such as fluctuations in world oil prices, macroeconomic conditions, and energy market sentiment. This study concludes that internal financial ratios have not become the main determinant in stock price movements in the oil and gas sector, so investors need to consider global external factors in making investment decisions.

Abstract

The property and real estate sector is one of the important sectors that contribute to the Indonesian economy, but in the 2021–2024 period, this sector experienced a decline in company value as reflected in market performance. This problem prompted this study, which aims to analyze the effect of capital structure on company value and examine the role of profitability as a mediating variable in property and real estate sector companies listed on the Indonesia Stock Exchange for the 2020–2024 period. This study uses a quantitative approach with the Partial Least Square-Structural Equation Modeling (PLS-SEM) method and the sample was determined through a purposive sampling technique on companies that meet the research criteria. The results of the study indicate that capital structure has a significant negative effect on company value and profitability, while profitability has a significant positive effect on company value and is proven to mediate the effect of capital structure on company value; this finding supports the Trade-off Theory regarding the importance of balance in the use of debt, but also shows limitations in the application of Signaling Theory in the property sector. This study concludes that excessive use of debt can reduce profitability and company value, so companies need to establish an optimal capital structure to maintain financial performance and increase investor confidence.

Abstract

: Research approach was employed using panel data regression analysis. Model selection was determined through a series of diagnostic tests, namely the Redundant Fixed Effects Test and the Hausman Test, which indicated that the Fixed Effects Model (FEM) is the most appropriate estimation method. The data used are secondary data obtained from the companies’ annual financial reports during the research period. The results show that, individually, liquidity has a statistically significant positive effect on firm value, whereas dividend policy and profitability do not exhibit significant effects. This suggests that a company’s ability to meet its short-term obligations serves as a positive signal to investors, enhancing their perception of the firm’s stability and trustworthiness in terms of performance. Meanwhile, the insignificance of dividend policy and profitability implies that investors do not rely solely on these factors when evaluating firm value instead, they may consider broader strategic, market, or macroeconomic indicators. The coefficient of determination (R²) is 0.848588, indicating that approximately 84.85% of the variation in firm value can be explained by the combined influence of dividend policy, profitability, and liquidity, while the remaining 15.15% is attributed to other factors outside the scope of this study.

Abstract

This study aims to analyze the influence of liquidity and profitability on firm value through the perspectives of educational and organizational management in manufacturing companies listed on the Indonesia Stock Exchange during the 2020–2024 period. The study employed a quantitative approach using a causal research design and explanatory method. The population consisted of 109 manufacturing companies in the basic and chemical industry subsector, while the sample comprised 19 companies selected through purposive sampling, resulting in 95 panel data observations. Secondary data were obtained from annual financial statements published on the Indonesia Stock Exchange website and corporate websites. Liquidity was measured using the Current Ratio (CR), profitability using Return on Assets (ROA), and firm value using Price to Book Value (PBV). Data analysis was conducted using panel data regression analysis with EViews 13 software. The results indicate that liquidity has a negative and significant effect on firm value, while profitability has a positive and significant effect on firm value. The findings also reveal that organizational effectiveness, leadership quality, institutional learning, and strategic resource management contribute to improving corporate competitiveness and sustainability. From the perspective of educational and organizational management, financial performance reflects managerial effectiveness and institutional governance quality in strengthening public trust and firm value in the capital market.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh struktur modal terhadap nilai perusahaan, menganalisis pengaruh profitabilitas terhadap nilai perusahaan, serta menganalisis pengaruh likuiditas terhadap nilai perusahaan pada perusahaan manufaktur sektor makanan dan minuman yang terdaftar di Bursa Efek Indonesia periode 2022–2024. Jenis penelitian yang digunakan adalah penelitian kuantitatif dengan pendekatan asosiatif. Populasi penelitian mencakup seluruh iverusahaan manufaktur sektor makanan dan minuman yang terdaftar di Bursa Efek Indonesia periode 2022–2024 yang berjumlah 83 perusahaan. Sampel penelitian sebanyak 48 perusahaan yang dipilih melalui iverusa purposive sampling berdasarkan kriteria iv erusahaan yang terdaftar secara berturut-turut selama periode penelitian, mempublikasikan laporan keuangan secara lengkap, tidak mengalami kerugian selama periode penelitian, serta memiliki data yang sesuai dengan variabel penelitian. Jenis data yang digunakan adalah data sekunder yang bersumber dari laporan keuangan tahunan perusahaan yang dipublikasikan melalui situs resmi Bursa Efek Indonesia. Teknik pengumpulan data dilakukan melalui metode dokumentasi dengan mengakses dan mencatat data keuangan yang relevan. Analisis data menggunakan analisis regresi data panel dengan bantuan aplikasi Eviews melalui uji pemilihan model yang meliputi uji Chow, uji Hausman, dan uji Lagrange Multiplier untuk menentukan model yang paling sesuai. Hasil penelitian menunjukkan bahwa struktur modal yang diproksikan dengan Debt to Equity Ratio (DER) berpengaruh terhadap nilai perusahaan, yang menunjukkan bahwa komposisi penggunaan utang dan ekuitas dalam pendanaan perusahaan dapat memengaruhi persepsi investor terhadap kinerja dan prospek perusahaan. Profitabilitas yang diproksikan dengan Net Profit Margin (NPM) juga berpengaruh terhadap nilai perusahaan, yang mengindikasikan bahwa semakin tinggi kemampuan iverusahaan dalam menghasilkan laba maka semakin tinggi pula nilai perusahaan karena meningkatnya kepercayaan investor terhadap kinerja perusahaan. Sementara itu, likuiditas yang diproksikan dengan Current Ratio (CR) tidak berpengaruh signifikan terhadap nilai perusahaan, yang menunjukkan bahwa kemampuan perusahaan dalam memenuhi kewajiban jangka pendek belum tentu menjadi pertimbangan utama bagi investor dalam menilai perusahaan pada sektor makanan dan minuman.
