Abstract

This research aims to design and implement an Internet of Things (IoT)-based nutrient control and monitoring system in the Hydroponic Tower system, as a solution to land limitations and manual monitoring challenges. The system utilizes a DS18B20 Temperature Sensor and a TDS Meter V1.0 KS0429 sensor for precision data acquisition, as well as an actuator in the form of a Yamano WP-103 pump and a DC 2W-160-15 Solenoid Valve controlled by an ESP32-DevKitC-1 Microcontroller. Data from the sensors is sent in real-time to the dashboard via the MQTT protocol, enabling automatic monitoring and control. This system successfully keeps environmental parameters such as pH, Temperature, and ppm in a stable range that is positively correlated with plant growth. This success was validated with a total harvest of 10,569kg and an average of 58.3grams per plant. In conclusion, the system is able to optimize the efficiency of tower hydroponic cultivation, offering an adaptive solution for precision farming in dense urban environments.

This research aims to explain the cash waqf management system by Citra Prakarsa Nusantara Foundation and its impact on cash waqf receipts. The research methodolgy employed is qualitative, utilizing data collection techniques such as interviews, observations, and documentation. The data sources for this research include the daily management head of CPN and the media head of CPN. The research findings describe the cash waqf management system by CPN that targets waqifs from abroad, providing significant amounts of cash waqf. Additionally, CPN’s cash waqf management demonstrates adequate attention to communication with waqifs, thereby enhancing trust and credibility in the foundation.

Abstract

The assessment of equity value serves as a crucial indicator in the banking sector, which plays a strategic role in the national economy. Fluctuations in PBV among listed banks on the IDX during 2020–2024 reflect dynamic market perceptions of banking performance. This study investigates the influence of intellectual capital and dividend policy on equity valuation with corporate risk disclosure (CRD) as an intervening variable. A quantitative research design was employed using panel data regression analysis. The sample consists of 20 banking companies listed on IDX for 2020–2024 period, with data processed through EViews software. The findings reveal that intellectual capital exerts a positive effect on equity valuation. Dividend policy and CRD demonstrate no significant influence. Furthermore, CRD does not mediate the relationship between the independent variables and equity valuation. The study highlights that equity value in Indonesia’s banking industry is primarily shaped by effective management of intellectual capital, rather than by dividend policy or CRD.

Abstract

This study aims to analyze the effect of Liquidity and Leverage on Stock Returns with Profitability as an intervening variable. The objects of the study were LQ45 Index companies listed on the Indonesia Stock Exchange (IDX) during the 2020– 2024 period. The method used was a quantitative approach with panel data regression analysis. The variables used included Liquidity (proxied by the Current Ratio) and Leverage (proxied by the Debt to Equity Ratio) as independent variables, Profitability (proxied by Return on Assets) as a mediating variable, and Stock Returns as the dependent variable. The results showed that Liquidity and Leverage had no significant effect on Stock Returns, while Profitability had a significant direct effect on Stock Returns. Furthermore, Liquidity had no significant effect on Profitability, but Leverage had a significant direct effect on Profitability. The mediation test using the Sobel test showed that Profitability did not significantly mediate the relationship between Liquidity and Stock Returns or between Leverage and Stock Returns. Management must prioritize strategies that can increase net profit and asset utilization efficiency. Increased profits will be directly reflected in share prices, benefiting investors and increasing stock returns.

Abstract

UMKM (Usaha Mikro, Kecil, dan Menengah) memiliki kontribusi besar terhadap perekonomian Indonesia, namun masih menghadapi berbagai tantangan dalam pengambilan keputusan yang tepat guna meningkatkan penjualan. Salah satu solusi yang ditawarkan adalah penerapan data analytics untuk mengolah data penjualan menjadi informasi yang dapat dijadikan dasar strategi bisnis. Penelitian ini bertujuan untuk menerapkan metode descriptive analytics pada data penjualan UMKM yang diperoleh dari platform publik Kaggle. Data tersebut mencakup atribut tanggal transaksi, jenis produk, jumlah order, harga, dan total penjualan. Metode yang digunakan mengacu pada tahapan CRISP-DM, dimulai dari pengumpulan data, preprocessing, eksplorasi data, hingga visualisasi menggunakan Google Colab dan library Python seperti Pandas, Seaborn, dan Matplotlib. Analisis dilakukan untuk menjawab tiga rumusan masalah: penerapan data analytics, temuan pola penjualan, serta strategi peningkatan penjualan. Hasil menunjukkan bahwa pendekatan ini mampu mengidentifikasi produk terlaris, tren penjualan bulanan, serta fluktuasi permintaan. Visualisasi tren penjualan dan statistik deskriptif berhasil mengungkap produk yang berkontribusi besar terhadap omzet serta bulan-bulan dengan performa tinggi atau rendah. Berdasarkan temuan ini, strategi bisnis seperti fokus promosi pada produk unggulan, penguatan stok saat puncak penjualan, serta evaluasi produk tidak laku dapat dirumuskan. Penelitian ini bersifat eksploratif dan ditujukan sebagai panduan praktis bagi pelaku UMKM yang belum familiar dengan data analytics. Rekomendasi lanjutan meliputi integrasi dengan metode prediksi dan penggunaan visualisasi interaktif.

Abstract

The mining sector in Indonesia exhibits a disparity between corporate profitability and equity valuation, indicating that non-financial factors may influence investors’ assessments. This study aims to examine the effect of Environmental, Social, and Governance (ESG) disclosure on equity valuation with profitability as a mediating variable. The research sample consists of mining companies listed on the Indonesia Stock Exchange during the 2020–2024 period. A quantitative approach with panel data regression analysis was employed. Data were collected from companies’ annual and sustainability reports and analyzed using EViews software. The results indicate that Environmental and Social Disclosure have no significant effect on equity valuation, while Governance Disclosure has a positive and significant effect. Environmental Disclosure negatively affects profitability, whereas Social and Governance Disclosure positively and significantly influence profitability. Profitability has a positive and significant effect on equity valuation but does not mediate the relationship between ESG disclosure and equity valuation. Simultaneously, ESG disclosure significantly affects both profitability and equity valuation. This study concludes that good corporate governance plays a crucial role in enhancing equity valuation, while environmental and social disclosures require further strengthening to generate optimal financial and market value impacts.
