Abstract

This study aims to examine the effect of institutional ownership and audit quality in moderating the relationship between free cash flow and earnings management of non-financial firms in Indonesia. This study uses 179 observations for the year 2019-2023 of non-financial companies listed in the Indonesia Stock Exchange and sampling technique used is proportionate stratified random sampling.  Then, data are analyzed using multiple linear regression analysis and moderated regression analysis (MRA). The study's findings suggest that free cash flow has positive effect on earnings management. It has been demonstrated that audit quality plays a role in reducing or mitigating the positive influence of free cash flow on earnings management. However, on the other hand, institutional ownership does not play a role in moderating the effect of free cash flow on earnings management. Unless audited by a reputable public accounting firm, investors and prospective investors should be cautious in funding businesses with significant free cash flow since it may encourage managers to engage in earnings management. If financial statements of a company are audited by a reputable public accounting firm, the manager’s motivation to engage in earnings management may be reduced. In order to explain how free cash flow affects earnings management, this study adopts a novel strategy by combining audit quality and institutional ownership characteristics as moderating variables.

Abstract

Utilization of forest plant seeds of suren (Toona sureni (Blume) Merr.), mimba (Azadirachta indica A.Juss.), mahogany (Swietenia mahagoni (L.) Jacq.), and saga (Adenanthera pavonina L.) for curing certain illness have long been practiced by traditional community. However, there were limited study on observing seeds bioactivity of those four species. This study aimed to analyze the toxicity activity of suren, mahoni, mimba, and saga seeds. The four seeds were initially macerated using 96% ethanol. The ethanol extracts were then tested for their toxicity effects on the Artemia salina larvae by Brine Shrimp Lethality Test (BSLT) method. BSLT results were presented through the Lethal Concentration 50 (LC50). The LC50values of ethanol extract of suren seeds, mahogany, mimba, and saga were 75, 84, 323 and 449 μg/mL, respectively. The four extracts had biological activity with LC50<1000 μg/mL, and suren seed extract was the most likely to have bioactivity because it had the lowest LC50value.

Abstract

Alstonia scholaris R.Br belongs to family Apocynaceae, is one of medicinal forest plant as traditional medicine to treat fever, malaria, cough with phlegm, diarrhea, diabetes, cholesterol-lowering, intestinal worms, acute rheumatism, ulcers, and hypertension. One of the causes of heart disease, atherosclerosis, and cancer is oxidative stress. The stress can be cured or reduced by taking antioxidant. Flavonoid, a phenol compound class, is one of the secondary plant metabolites that function as antioxidant. This paper determines total levels of phenol, flavonoid, and antioxidant activity of Alstonia *stem bark extract (Alstonia scholaris R. Br). Quantitative determination of total phenolics with the folin-ciocalteu method expressed as mg of gallic acid equivalent (GAE) per gram of extract, total flavonoids content by AlCl₃ method expressed as Quercetin equivalent (QE), and in vitro antioxidant activities with DPPH (2,2-diphenyl-1-picrylhydrazyl) method expressed in terms of IC₅₀ (inhibition concentration). Results show that extraction of three replicates in maceration with 96% ethanol yielded 4.19% filtrate. The total phenolic content was 51.50 mg GAE /g extract, while the total flavonoid content was 0.35 mg QE /g extract. IC₅₀ value of antioxidant activity assay of stem bark extract was 211.54 µg/mL.

Abstract

The management of zakat is crucial in Islamic finance, and digital platforms have increasingly been adopted to enhance transparency, security, and trust among users. This study examines the software engineering aspects of zakat management platforms, focusing on these critical dimensions. The research aims to identify key software design considerations that can improve transparency, ensure data security, and foster user trust within digital zakat platforms. A mixed-method approach is used, involving both qualitative interviews with zakat management professionals and quantitative analysis of platform users' perceptions. The findings suggest that clear communication regarding financial transactions, robust data protection measures, and user-friendly interfaces are essential for building trust. Furthermore, implementing blockchain technology was found to significantly enhance transparency and security. The study concludes that for zakat platforms to be successful, they must not only comply with Shariah principles but also integrate advanced technology solutions that align with user expectations for security and transparency. This research provides a comprehensive framework for the development of zakat management platforms that can be adopted by stakeholders in the Islamic finance sector.

Abstract

Pantai merupakan ekosistem pesisir yang memiliki fungsi ekologis penting dalam menjaga keseimbangan lingkungan dan menjadi habitat bagi berbagai organisme laut. Namun, tingginya aktivitas wisata dan kurangnya kesadaran masyarakat dalam pengelolaan sampah menyebabkan peningkatan pencemaran di kawasan pesisir, termasuk di Pantai Sukon Sigli, Kabupaten Pidie. Kondisi ini mendorong Program Studi Pendidikan Biologi Universitas Jabal Ghafur untuk melaksanakan kegiatan pengabdian masyarakat bertajuk Gerakan Bersih Pantai Sigli: Selamatkan Ekosistem, Jaga Kehidupan Laut, dengan tujuan meningkatkan kepedulian lingkungan dan mengurangi timbunan sampah di kawasan pantai. Kegiatan dilaksanakan pada tanggal 27 Oktober 2025 dengan melibatkan 25 peserta yang terdiri atas dosen dan mahasiswa. Metode pelaksanaan meliputi sosialisasi pentingnya menjaga kebersihan pantai, pengamatan kondisi lingkungan pesisir, serta aksi bersih pantai dengan mengumpulkan sampah organik dan anorganik yang ditemukan di area tersebut. Sampah yang terkumpul sebanyak dua kantong besar kemudian diserahkan kepada petugas pantai untuk diproses lebih lanjut sesuai prosedur pengelolaan sampah yang berlaku. Hasil kegiatan menunjukkan adanya dua capaian utama, yaitu meningkatnya kebersihan fisik Pantai Sukon Sigli serta tumbuhnya kesadaran ekologis pada mahasiswa dan masyarakat tentang pentingnya menjaga kebersihan lingkungan pesisir. Selain memberikan dampak langsung terhadap estetika pantai, kegiatan ini juga memperkuat peran perguruan tinggi sebagai agen perubahan dalam upaya pelestarian lingkungan.
