This study analyzes the extent which firm performance, operating expenses, and inventory affect the net profit of manufacturing issuers in the Indonesian steel sub-sector listed on the Indonesia Stock Exchange (IDX) during 2020–2024. Firm performance is measured using Return on Assets (ROA) and Return on Equity (ROE), operating expenses are represented by the Operating Expenses Ratio (OER), inventory is measured using Inventories Turnover (ITO), and net profit is assessed through the Net Profit Margin (NPM). The research applies a quantitative descriptive method and panel data regression using the Common Effect Model (CEM). Quarterly financial statements from PT Krakatau Steel (KRAS), PT Saranacentral Bajatama (BAJA), and PT Lionmesh Prima (LMSH) were used, totaling 60 observations. The results show that ROA and ROE have a significant positive effect on NPM, indicating that efficient management of assets and equity contributes to higher profitability. Meanwhile, OER and ITO have negative but insignificant effects, suggesting that operating expenses and inventory turnover do not strongly influence net profit in an industry with high fixed costs such as steel. Simultaneously, all variables significantly affect NPM, with an R-Square value of 66.25%, indicating that the research model is able to explain most of the variation in net profit highlighting the importance of asset and equity management in enhancing company profitability.

The inherent fluorescent properties of anti-leukemic drugs offer unique advantages for real-time therapeutic tracking and optimization. In this study, we systematically screened the absorption and emission spectra of 82 leukemia-related compounds, identifying 28 autofluorescent drugs suitable for fluorescence-based optical concentration monitoring. Excitation and emission parameters were evaluated across various solvents (DMSO, fetal bovine serum, and culture media), revealing solvent-dependent spectral changes, intensity variations, and effect on detection limits. These 28 compounds were further assessed for cytotoxicity screening in case of drug-naive and drug-resistant K562 leukemia lymphoblast cells. By correlating their spectral properties with cytotoxic responses, our study establishes a robust framework for fluorescence-assisted drug profiling, enabling pharmacokinetic insights, resistance prediction, and informed therapeutic adjustments. These findings underscore the translational potential of fluorescence-based methodologies in supporting precision medicine for leukemia treatment.

Kurangnya pemahaman masyarakat mengenai perbedaan antara obat generik dan obat bermerek menjadi salah satu alasan mengapa penggunaan obat generik masih rendah, terutama di daerah perbatasan Indonesia dan Malaysia. Banyak orang berpikir bahwa obat generik kualitasnya lebih buruk dibandingkan obat bermerek, padahal keduanya sama-sama efektif dan aman. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan kesadaran warga Desa Merubung, Kecamatan Tekarang, mengenai pentingnya memahami perbedaan antara obat generik dan bermerek. Kegiatan ini dilakukan dengan metode edukasi partisipatif melalui penyuluhan interaktif menggunakan media visual berupa Power Point yang diikuti oleh 40 peserta. Untuk mengukur tingkat pemahaman peserta, dilakukan uji coba sebelum dan setelah penyuluhan. Hasil menunjukkan adanya peningkatan signifikan pada nilai rata-rata peserta, yaitu dari 58,00 meningkat menjadi 93,25 setelah penyuluhan, yang menunjukkan bahwa pemahaman masyarakat terhadap materi meningkat. Edukasi ini terbukti efektif dalam meningkatkan kesadaran masyarakat untuk menggunakan obat secara rasional dan bijak. Kegiatan serupa diharapkan dapat berlanjut terus-menerus agar masyarakat di daerah perbatasan semakin memahami dan mandiri dalam penggunaan obat

This study aims to comprehensively and in-depth examine the influence of good corporate governance (GCG) and sustainability disclosure on firm performance. The research hypotheses are tested using a panel data regression approach. The study sample comprised non-financial companies listed on the Indonesia Stock Exchange (IDX) from 2016 to 2022, totalling 972 firm-year observations. This study finds that GCG and sustainability disclosure significantly positively affect firm performance. Furthermore, we conducted additional analysis separating young and older firms, and the results are consistent with the main findings. This study's initial contribution is to integrate the important pillars of corporate sustainability, consisting of GCG and sustainability disclosure, into a single model to influence firm performance in Indonesia. This study expands the study of differences in corporate governance between developing and developed countries. Finally, this study introduces a new dimension by analysing company development stages based on age.

The presence of fountains in public areas can create a comfortable atmosphere for everyone. Green spaces can provide ecological and aesthetic benefits, so fountains that combine ecological and aesthetic functions were essential. Based on this, research was conducted to test the performance of the water flow control system and nozzle movement control in a fountain integrated with automatic plant irrigation. Water flow testing was conducted by setting the dimmer at angles of 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, and 65°. Nozzle movement testing was carried out by giving servo motor movement commands at angles of 50° – 130° and gradually adding an angle of 4° for each test. The data collected in the study were water flow and nozzle movement accuracy. Based on the test results, the minimum flow rate recorded was 0.141 l/s at an angle of 20°, the maximum flow rate reached 0.775 l/s at an angle of 65°, while the average flow rate from the tests was 0.490 l/s. The nozzle movement system showed an average accuracy of 98.84%, indicating that the system performs very well. The test results showed that the water discharge control and nozzle movement systems were able to produce controlled water jets, both in terms of flow rate and direction.

Although various studies have examined the economic and political impacts of product boycotts, research focusing on the implementation of economic boycotts driven by religious fatwas in the Indonesian context remains scarce. This study seeks to fill that gap by analyzing the Indonesian Ulema Council (Majelis Ulama Indonesia) Fatwa No. 83/2023 concerning support for the Palestinian cause and the boycott of pro-Israel products, within the framework of fiqh siyasah and the concept of economic warfare. Using a descriptive qualitative method with a contextual content analysis approach, this research explores the substance and implications of the fatwa. The analysis finds that the fatwa emphasizes the moral and political dimensions of Muslim solidarity, positioning boycotts and the distribution of zakat and infaq as forms of ethical and humanitarian responsibility rather than economic instruments. Furthermore, the fatwa illustrates the integration of fiqh siyasah principles into contemporary discourse on global justice and Muslim solidarity. This study contributes to a deeper understanding of how religious authority can influence moral reasoning and collective action within Islamic economic thought. The findings provide conceptual insights for scholars, policymakers, and community leaders on the role of Islamic legal perspectives in shaping ethical responses to global political issues, while promoting peaceful and principled engagement in international relations.

This study aims to examine the influence of Return on Assets (ROA) and Net Profit Margin (NPM) on Firm Value, as well as the moderating role of Institutional Ownership. Firm Value is a crucial indicator reflecting market perception of a company’s performance and future prospects, with profitability and corporate governance being key influencing factors. ROA and NPM were used as measurement of profitability, while Institutional Ownership was considered as an external monitoring mechanism that plays an important role in corporate governance. A quantitative approach is employed using secondary data from 23 companies consistently listed in the LQ45 index during 2018–2022, resulting in 115 firm-year observations. Data analysis was conducted using a fixed effect regression model and moderated regression analysis (MRA), processed with EViews 10. The results showed that ROA had a significant positive effect on Firm Value, while NPM did not have any significant effect. Additionally, Institutional Ownership strengthened the relationship between ROA and Firm Value but weakens the influence of NPM on Firm Value. These findings indicated that institutional investors play an effective supervisory role in optimizing asset management, although they may restrict managerial flexibility in short-term profitability strategies.

Global climate change, characterized by increasing drought intensity, poses a serious threat to the sustainability of agricultural production. Sorghum (Sorghum bicolor L.) is a strategic drought-tolerant commodity, but studies on its secondary metabolite response are still limited, especially in superior varieties. This study aims to analyze the effect of drought stress on the flavonoid and phenol content in water extracts of Super 1, Mandau, and Suri 4 sorghum varieties. The three varieties were planted on coastal land with four different irrigation frequencies (daily, every 4 days, every 5 days, and every 6 days), then extracted and analyzed for flavonoid and phenol content using spectrophotometry. The results of the ANOVA analysis showed that drought stress had a very significant effect on flavonoid and phenol content (p < 0.05). The Super 1 variety with irrigation every 5 days produced the highest flavonoid content, while the highest phenol accumulation was obtained in the combination of Super 1 and irrigation every 6 days. Conversely, conditions without stress (daily irrigation) reduced the content of both metabolites, especially in the Mandau variety. These findings confirm that moderate to severe water stress can increase the biosynthesis of secondary metabolites as an adaptive defense mechanism in plants
