Academic supervision plays a strategic role in ensuring the quality of learning in educational institutions, including at YLA Cibadak Vocational School. This research aims to explore the role of academic supervision in improving the quality of learning through a collaboration-oriented approach, developing teacher competence, and pedagogical innovation. Using descriptive qualitative research methods, data was obtained through observation, in-depth interviews, and analysis of supervision documents. The research results show that effective academic supervision not only functions as an evaluation tool, but also as a medium for educational transformation that involves teachers as strategic partners. The main findings underline the importance of two-way communication patterns, preparing needs-based follow-up plans, and empowering teachers through ongoing training and mentoring. This research recommends a supervision model based on empathy and local contextualization that is able to answer the unique needs of SMK YLA Cibadak, as well as being an inspiration for other institutions. With this approach, academic supervision can be a driving force in creating a dynamic, adaptive and quality-oriented learning ecosystem.

In this review, we undertake an in-depth survey of the traditional as well as modern methods used in finding solutions for partial differential equations (henceforth PDEs). We categorise these equations into three main kinds: elliptic, parabolic, and hyperbolic. We also give illustrative examples of these PDEs and discuss the applications of them in a range of fields. This range extends from fluid dynamics (hydrodynamics), as well as thermal (heat) conduction, to quantum mechanics. Our exploration features a number of analyses used in this regard such as variable splitting or defactorising in addition to the transforms invented by Fourier and Laplace. Not only this but also this survey takes in numerical methods ranging from grid-based (finite difference), mesh-based (finite element) to spectral. Also discussed in this paper is a range of special techniques that ranges from the variational techniques, Green's (fundamental solution) functions to perturbation (also known as Asymptotic expansion in addition to sketching the latest developments with respect to computational methods. This review also sheds light on current challenges that confront addressing complicated PDEs especially those nonlinear and multi-variable. In this regard, the paper calls for more research in order to develop more effective methods. The paper maps out the importance of PDE usages in real-life and its potential for more related discoveries in the future particularly with respect to areas such as machine learning and quantum computing.

Hydroelectric Power Plants (HPP) are a type of power plant that utilizes renewable energy from water flow. The hydroelectric system works by converting the kinetic energy of flowing water into mechanical energy, which is then converted into electrical energy. Water flows through a penstock directed towards the turbine, where it strikes the turbine blades, causing rotation. To maintain the stability of the turbine's rotational speed at the Maninjau HPP, a governor system is used. The Maninjau HPP consists of four generating subunits with a nominal rotational speed of 600 rpm. The governor system functions to stabilize the turbine's rotation at the nominal speed of 600 rpm, as the speed affects the generator's output frequency. The stabilization process is carried out by adjusting the Guide Vane openings, which are the blades surrounding the turbine. The Maninjau HPP has a speed drop of 3%, with a frequency reduction of 1.5 Hz. Additionally, a frequency change of 0.1 Hz will result in a load change of 0.13 MW.

This article is made to learn the definition, components, and calculation formula of the Market Entry Barriers Component Index and Function Index, where these two measuring instruments are very important in analyzing the market. The function of the Market Entry Barriers Component Index is to evaluate the level of difficulty that a company will face in entering a pre-existing market. The way to evaluate it is by looking at obstacles such as fixed costs, production capacity, regulation, and production. For the Function Index itself, it functions to see how much efficiency will occur and includes distribution, information flow, and market mobility. This article also aims to provide an example of how the calculation system for the two indexes works. Through this understanding, readers and companies can formulate more appropriate strategies in dealing with obstacles and taking advantage of opportunities in the market.

Background: The endocrine system is a network of glands that produces body hormones to regulate various body functions, such as growth, metabolism, regulation reproduction, and homeostasis. This research aims to provide a comprehensive overview of the role of the endocrine system, the function of the hormones produced, and the impact of their disorders on health. The research was carried out using a literature study method of six relevant national journals published in the last five years. The results of the analysis show that the endocrine system plays an important role in maintaining body balance through feedback mechanisms and interactions with the nervous system. Disorders of glands such as the pancreas, thyroid and adrenals can lead to serious illnesses, including diabetes mellitus, hypothyroidism and Cushing's syndrome. This study emphasizes the importance of understanding the endocrine system for the development of early detection and intervention strategies for hormonal disorders. It is hoped that the research results can become a reference for medical personnel and scientists in improving the quality of public health.

Computer assembly is the process of putting together various hardware components to ensure the computer functions optimally. To assemble a computer correctly, a deep understanding of its hardware, both logically and physically, is essential. Additionally, in order for the computer to be used for its intended purpose, software installation is required. This installation includes programs like Microsoft Windows, Microsoft Office, and others, which help adjust the software to the installed hardware and unpack compressed files. This community service activity is held at SMK Lowis Sakti, Sakra Timur, focusing on computer assembly and installation training. This process plays a vital role in the development and maintenance of efficient and reliable computer systems. A comprehensive knowledge of assembly and installation procedures is necessary to ensure optimal system performance and security. Therefore, the goal of this training is to equip SMK Lowis Sakti students with the skills to assemble and install computers independently, enabling them to apply this knowledge both in school and in the workforce.
