SYSTEMATIC LITERATUR REVIEW MEMBANGUN SISTEM PENGENDALIAN: MENGURANGI RISIKO KECURANGAN MELALUI FRAUD TRIANGLE_SYSTEMATIC LITERATUR REVIEW
No full textTinjauan literatur sistematis ini mengeksplorasi 15 artikel yang membahas peran sistem pengendalian internal dalam mengurangi risiko kecurangan melalui pendekatan fraud triangle, yang meliputi tekanan, kesempatan, dan rasionalisasi. Penelitian menemukan bahwa tekanan yang dialami karyawan, baik dari kondisi finansial maupun tuntutan pekerjaan, dapat meningkatkan kemungkinan terjadinya kecurangan. Selain itu, kelemahan dalam sistem pengendalian memberikan peluang bagi individu untuk melakukan tindakan curang tanpa terdeteksi, sedangkan rasionalisasi digunakan untuk membenarkan perilaku tersebut. Penelitian ini menekankan pentingnya memperkuat sistem pengendalian melalui audit yang rutin, penerapan sistem pelaporan yang aman, dan pengembangan budaya organisasi yang menjunjung tinggi etika. Dalam konteks sektor publik, terutama di pemerintahan daerah, pengawasan yang ketat terhadap pengeluaran sangat diperlukan untuk mencegah korupsi. Rekomendasi yang dihasilkan mencakup pelatihan etika untuk karyawan dan evaluasi berkala terhadap sistem pengendalian, serta perlunya penelitian lebih lanjut untuk memahami faktor-faktor yang memengaruhi efektivitas sistem pengendalian di berbagai konteks.

Kidney Stone Treatment Using the Percutaneous Nephrolithotomy Method (PCNL)
Full text linkKidney stones are a serious condition that often occurs in the wider community. The presence of this disease is influenced by genetic factors, diet, dehydration, irregular lifestyle, and unhealthy lifestyle. One of the treatments used to treat kidney stones is Percutaneous Nephrolithotomy (PCNL) for kidney stones measuring more than two centimeters. This study aims to find out about kidney stone treatment using the PCNL method. The method used is a literature study by discussing five study focuses, namely (1) healthy kidney structure and its role in maintaining body balance, (2) kidney structural abnormalities and their impact on health, (3) kidney stone treatment methods and their impact on health, (4) PCNL as a modern treatment solution for kidney stone sufferers, and (5) the process of implementing PCNL in kidney stone treatment. It can be concluded that healthy kidneys are vital organs with integrated structures and functions to maintain the physiological balance of the body and play a role in producing the hormones renin, erythropoietin, and calcitriol. Kidney disorders that often appear are kidney stones caused by waste in the blood or crystallized chemicals such as calcium and oxalic acid. Pharmacological therapy is a therapy that is often used to treat kidney stones using medical drugs and also surgery, but this method has side effects due to the drugs given. PCNL is a non-invasive treatment that utilizes sophisticated medical technology to treat kidney stones. PCNL treatment is done by making a small incision in the skin of kidney stone sufferers so that it does not have significant side effects. PCNL has a high success rate for the treatment of kidney stone
Implikasi Kebijakan Pajak Digital Terhadap Aktivitas Ekonomi Generasi Z di Era Transformasi Digital Indonesia
Full text linkThis research examines the implications of digital tax policy on Generation Z\u27s economic activities in Indonesia\u27s digital transformation era. The study aims to analyze the impact of digital tax policies on consumption behavior and business ventures involving Generation Z, examine their responsiveness to these policies, identify challenges and opportunities in adapting to the increasingly regulated digital economy, and measure their contribution to state revenue through digital tax compliance. Using literature review and library research methodologies, this study analyzes how digital tax policies, including the implementation of 10% Value Added Tax (VAT) on digital products and services, influence Generation Z\u27s consumption patterns and business strategies. The findings reveal that the implementation of this policy has resulted in significant changes in Generation Z\u27s digital consumption behavior, where they tend to become more selective and prioritize spending on essential needs. As MSMEs operators, Generation Z faces challenges in adapting to this policy, particularly in adjusting profit margins and marketing strategies. Some MSMEs have responded by adopting product diversification strategies and digital marketing innovations, while others struggle to adapt due to limited access to technology and financial literacy. The research concludes that while digital tax policies present challenges for Generation Z\u27s economic activities, they also promote increased tax literacy and innovation in business strategies. The study recommends the necessity of involving Generation Z in the policy-making process to ensure more effective and equitable implementation of digital tax policies.Keywords: digital tax, generation z, digital econom

Penerapan Teknologi Reverse Osmosis Berdaya Panel Surya Untuk Pemurnian Air Sumur dalam Rangka Penyediaan Air Bersih di SDN Inpres Arso X: Proyek Percontohan
Full text linkThe Community Service (PkM) activity has been carried out with the PkM partner, SD Negeri Inpres Arso X, in Keerom District, Papua, Indonesia. The issue faced by the PkM partner is its dependence on well water as the primary source of water for daily activities. However, the well water does not meet hygiene standards and is contaminated by bacteria, chemicals, or other pollutants that pose health risks, especially for children. Additionally, the limited access to electricity in Arso X creates a need for alternative power to operate the water purification system. This PkM activity aims to address these issues by implementing a solar-powered Reverse Osmosis system to purify the well water owned by the PkM partner. The PkM activities consist of three stages. First is the preparation stage, where the PkM team surveyed the location and interviewed the PkM partner. The next step involved designing the solar panel mounts, the RO system, and supporting electrical components. During the implementation stage, the PkM team conducted awareness sessions via short interactive lecture on the importance of clean water and the role of renewable energy, followed by a demonstration of water purification using solar-powered RO technology. The monitoring and evaluation phase showed that the PkM partner has benefited from the application of the solar-powered RO technology. Furthermore, regular maintenance of the RO system and solar panels is necessary.
