The world of business and industry (DUDI) is currently experiencing a significant transformation due to the influence of technology, this is characterized by machines replacing human labor or what is often known as the Industrial Revolution 4.0. Vocational High Schools (SMK) as providers of Human Resources who are ready to work have big challenges. Based on the results of observations made on the competence of Office Management and Business Services Vocational Schools in Salatiga, Boyolali and Surakarta, there is one subject in Automation and Financial Governance that still uses conventional calculations. Based on the above background, this research focuses on developing web-based petty cash learning media as a technological innovation to answer the needs of human resources who master technology. The research method used is R&D (Research and Development) which starts from the analysis, design, development, implementation and evaluation stages. The research results show that the web-based petty cash system is suitable for use. The Feasibility Test showed that information systems experts got a final score of 4.67, material and content experts got a final score of 4.35, and learning media experts got a final score of 4.67. So it can be said that in terms of system, material, content and learning media, the petty cash system as a learning media in vocational schools is "worth using". The results of responses from teacher practitioners show high interest in the application being developed and it is hoped that it will be able to facilitate the learning process on technology-based petty cash material. It is hoped that the resulting system can be used as a learning medium in vocational schools, especially in office management and business service skills competencies. However, further research needs to be carried out to be able to measure the effectiveness of the petty cash system being developed.

The aim of this study is to study the regulation of unfair business competition in government goods/services combination (PBJ) and study the consideration of the Komisi Pengawas Persaingan Usaha (KPPU) in resolving the issue of unfair business competition construction Mandala Krida Stadium. Infrastructure development is a way of turning the wheel of society's economy. Increasing infrastructure development needs have prompted the government to create a framework for attracting private investment and participation in infrastructure projects. that the construction services sector is key in infrastructure development, which directly affects economic growth. Unfair business competition can hinder the development of quality and efficient infrastructure.  The type of research used is the juridic normative. The result of this study is that the PBJ Competition Act has provided a sufficient basis for regulating and monitoring the competition of enterprises in the PBJ sector. To more ideal conditions, improvements are needed in terms of implementation and law enforcement. Strengthening inter-agency coordination, enhancing the competence of entrepreneurs, and improving supervisory capabilities, as well as the more effective use of technology can help create a healthier and fairer competitive climate in the PBJ in Indonesia. KPPU established that there has been a violation of Article 22 of the Business Competition Act. KPPU decided to grant administrative sanctions to the entrepreneurs involved, including fines and prohibition from participating in the PBJ for a certain period of time. Tujuan dari penelitian ini untuk mengkaji pengaturan persaingan usaha tidak sehat dalam pengadan barang/jasa pemerintah (PBJ) dan mengkaji pertimbangan Komisi Pengawas Persaingan Usaha (KPPU) dalam memutus perkara persaingan usaha tidak sehat pembangunan Stadion Mandala Krida. Pembangunan infrastruktur adalah cara untuk memutar roda ekonomi masyarakat. Meningkatnya kebutuhan pembangunan infrastruktur mendorong pemerintah membuat kerangka kerja untuk menarik investasi dan partisipasi swasta dalam proyek-proyek infrastruktur salah satu contoh yaitu pengadaan tender pembangunan. bahwa sektor jasa konstruksi adalah kunci dalam pembangunan infrastruktur, yang secara langsung mempengaruhi pertumbuhan ekonomi. Ketidakadilan dalam persaingan usaha dapat menghambat pembangunan infrastruktur yang berkualitas dan efisien.  Jenis penelitian yang digunakan adalah yuridis normatif. Hasil dari penelitian ini adalah UU Persaingan Usaha dan Perpres PBJ telah memberikan dasar yang cukup untuk mengatur dan mengawasi persaingan usaha di sektor PBJ. Untuk mencapai kondisi yang lebih ideal, diperlukan peningkatan dalam hal implementasi dan penegakan hukum. Penguatan koordinasi antar lembaga, peningkatan kompetensi pelaku usaha, peningkatan kapabilitas pengawasan, serta pemanfaatan teknologi yang lebih efektif dapat membantu menciptakan iklim persaingan yang lebih sehat dan adil dalam PBJ di Indonesia. KPPU menetapkan bahwa telah terjadi pelanggaran Pasal 22 UU Persaingan Usaha. KPPU memutuskan untuk memberikan sanksi administratif kepada para pelaku usaha yang terlibat, termasuk denda dan larangan berpartisipasi dalam PBJ untuk jangka waktu tertentu.

The purpose of this study is to determine the characteristics of the cooling system on the new design of the Kartini Reactor plate fuel based on numerical calculations (Computational Fluid Dynamics). The fuel plate model was simplified and made in 3D. The model dimensions are 17.3 mm x 68 mm x 900 mm. The space between the two plates called the narrow rectangular channels has a gap of 2 mm. On these simulations a heat flux of 10612,7 watt/m2 was used which was obtained from the MCNP calculation program. Simulations were conducted in a steady state condition and single-phase model laminar flow of an incompressible fluid through the gap between the two fuel plates. This simulation uses UDF (User Define Function) to approach heat flux behaviour that follows the neutron distribution in the reactor core. The simulation results show that the maximum temperature that occur at a flow rate of 0.01 m/s was 43.5 °C.
