Data collection techniques in this research used observation, interviews and document study techniques. The data analysis technique in this research uses the Miles and Huberman model, namely data collection, data reduction, data presentation, as well as drawing conclusions and verification. The research procedure is carried out in three stages, namely the preparation stage, the implementation stage, and the completion and report preparation stage. The results of the research show that in class V of SD Negeri 198/I Pasar Baru there are several learning problems, such as: Low interest in learning from students in science subjects, low learning activity of students, and low interest in reading from students in science subjects.

Abstract

Introduction: Mercury as the source of free radicals can trigger the activation of oxidative stress pathways. With its high toxicity, it can cause hepato-renal injuries. There have been many studies on mercury toxicity in various organs, but there are still few scientific studies that examine the hepato-renal injuries caused by mercury through the oxidative stress pathway. This study was conducted to investigate the triggering of the oxidative stress pathway due to mercury exposure in hepato-renal injuries. Methods: Research using randomized true laboratory experiment method with post-test control group design. The number of samples used was 28 Wistar rats. The research group consisted of 2 groups, control group was given aquadest ad libitum, and intervention group was given water contaminated with mercury per oral once a day (15 kg/WB). The treatment period was 14 consecutive days and on the 15th day, blood samples were taken. Oxidative stress marker was assessed by examining MDA and GPx levels and hepato-renal injuries were assessed by examining liver function (ALT and AST) and kidney function (ureum and creatinine). The collected data were analyzed by independent t-test with 95% confidence level; significant if p>0.05. Results and Discussion: The study found that mercury can trigger the activation of oxidative stress pathways and have an impact on hepato-renal function. Conclusion: Research still needs to be continued to prove that impaired hepato-renal injuries also occur at the cellular histomorphologic and discover other biomolecular mechanisms such as activation of inflammatory pathways that can also cause organ damage.

Abstract

The banana chips MSME (Micro, Small, and Medium Enterprise) in Ranu Agung Village faces marketing challenges due to its reliance on conventional methods and limited digital capabilities. This community service initiative aimed to enhance the digital marketing capacity of MSME actors through rebranding training and social media optimization. The implementation involved initial field observation to assess partner needs, logo design training using Canva, social media utilization workshops focusing on Instagram and Facebook, and a one-month mentoring period. The results indicate significant improvement in participants' abilities to develop product visual identities, manage social media accounts, and independently produce promotional content. Additionally, digital engagement and product orders increased by 30% during training. These findings suggest that digital marketing strategies tailored to the specific needs of MSMEs can significantly impact their business development. The success of the program was further supported by effective collaboration between the implementation team and the MSME partner, as well as an adaptive approach to overcoming technical constraints.

Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh Weighted Average Cost of Capital (WACC), keputusan keuangan, dan kebijakan dividen terhadap strategi pendanaan pada PT Astra International Tbk tahun 2024. Efisiensi biaya modal menjadi fokus utama, mengingat perannya yang krusial dalam mengoptimalkan nilai perusahaan dan mendukung keberlanjutan pertumbuhan. Penelitian menggunakan pendekatan studi kasus deskriptif dengan memanfaatkan data sekunder dari laporan keuangan resmi, publikasi pasar modal, dan literatur ilmiah terkait. Hasil penelitian menunjukkan bahwa PT Astra International Tbk secara konsisten menyesuaikan struktur modal dan kebijakan dividen sesuai dinamika pasar serta tujuan strategis jangka panjang. Perusahaan mempertahankan keseimbangan proporsional antara penggunaan utang dan ekuitas untuk memaksimalkan efisiensi WACC, yang pada tahun 2024 tercatat sebesar 11,41%. Temuan ini menegaskan pentingnya sinergi antara pengelolaan struktur modal, kebijakan dividen yang adaptif, dan keputusan keuangan berbasis data dalam membentuk strategi pendanaan yang efektif. Penelitian ini memberikan kontribusi teoritis pada kajian manajemen keuangan korporat dan menawarkan implikasi praktis bagi pengambil keputusan di perusahaan konglomerasi, khususnya dalam menghadapi tantangan fluktuasi pasar dan kebutuhan investasi berkelanjutan.
