Examining the Legal Standing of IKN Authority Regulations within Indonesian’s Legislation System

This study scrutinizes the status of the regulations enacted by the Nusantara Capital City Authority (IKN Authority) within the Indonesian legislative hierarchy, based on Law Number 3 of 2022, also known as the IKN Law. A normative research approach underpins this analysis, utilizing legislative and conceptual methodologies. The investigation concludes that the IKN Law’s Article 5 paragraph 6, was drafted to accommodate all regulations formulated by the IKN Authority. These regulations, born out of the authority's attribution, hold an equivalent standing to those issued by a minister, institution, or agency at the central level given that the IKN Authority is an institution at the ministerial level. Consequently, the formulation of these regulations adheres to the rules governing central-level regulations, with the Supreme Court conducting their review. The unique aspect is the subject matter, which relates to the governance structure of the IKN Authority. Moreover, the formulation of regulations by the IKN Authority should: 1) Define the IKN entity’s position as a unique regional government entity; 2) Outline the types of regulations to be enacted; 3) Clarify the source of authority, which is attribution-based; 4) Specify its position in the hierarchy, equivalent to Regional Regulations; 5) Detail the formulation process and treatment, aligning it with the creation of regional legal products; 6) Elucidate the subject matter of the Regulatory Authority; and 7) Highlight the review process, which can be escalated to the Supreme Court

Thermal stability and light transmission capability of nano TiO2 enhanced phase change material as thermal energy storage

InPhase Change Material (PCM) already pick up some interests among recent researchers and engineers due to its unique characteristic of storage and releasing high quantity of heat energy during phase transition process. However, there's some disadvantages for this material such as low absorption of irradiance and super cooling phenomena occurred. To overcome this problem high conductive nanoparticles are dispersed in to the PCM resulting a new composite called nano-enhanced PCM (NEPCM). In this present paper, the impact of adding Titanium (IV) oxide nanoparticles (TiO2) on pure paraffin wax also was investigated. Output reveal that NEPCM have greater thermal stability than pure PCM. When increasing the %wt, the thermal stability also increases, as shown clearly when using Sodium Dodecylbenzene Sulfonate (SDBS) as surfactant

Thermal conductivity, reliability, and stability assessment of phase change material (PCM) doped with functionalized multi-wall carbon nanotubes (FMWCNTs)

The thermal properties of Phase Change Material (PCM) can be altered by introducing nanoparticles, and composite formed from the addition of nanoparticles are termed Nano-Enhanced Phase Change Materials (NEPCM). In the present study, the enhancement of thermal conductivity and feasibility study of dispersing multi-walled carbon nano tubes (MWCNTs) and functionalized MWCNT (FMWCNTs) in various mass fractions (AFMW-0.1, AFMW-0.3, AFMW-0.5, AFMW-0.7, AFMW-1.0) into the Plusice A70 PCM were examined. Differential scanning calorimetry (DSC) and TEMPOS thermal analyzer measured the latent heat storage, melting temperature, and thermal conductivity of the nano PCM composite. The thermal conductivity measured for the prepared nanocomposite showed a 109.5% enhancement for 1.0 wt% of non-functionalized MWCNT and 150.7% enhancement for 1.0 wt% of functionalized MWCNT compared to pristine PCM's thermal conductivity. This statement concluded that 50% enhancement for a 1.0 wt% of functionalized MWCNT compared to non-functionalize MWCNT immersed in A70 PCM. The nano composite PCM was thermally stable up to 200 °C and no chemical reaction takes place between the base PCM and nanoparticles. The result shows that the microscopic structure remained stable for the nanocomposite while the optical transmittance reduced noticeably for the nanocomposite relative to pristine A70 PCM. It can be concluded, the prepared nano composite PCM may be useful for solar thermal, photovoltaic thermal system, and low concentrated photovoltaic thermal system applications

Recent progresses and challenges in cooling techniques of concentrated photovoltaic thermal system: A review with special treatment on phase change materials (PCMs) based cooling

Concentrated Photovoltaic (CPV) system is one of the efficient and economical photovoltaics (PV) technologies. The fundamental principle of using CPV system is a substitution of expensive cell area with inexpensive optics. Concentrating the solar radiation on small areas enhances the power output. However, operating at high temperatures can potentially impair their life span and performance. Thus, cooling medium plays a crucial role in refining the CPV system's efficiency. The integration of the CPV system with Phase change materials (PCMs) provides a state-of-the-art hybrid design for both thermal and electrical outputs, suggesting a better utilization of solar energy. Nano-enhanced Phase Change Materials (NePCMs) were demonstrated to be the best combination for optimal behavior, such as storing and releasing energy quicker during the phase transition process without help from external systems. Key objective of this review article is to present the latest works and technical challenges on the application of PCMs and NePCMs in Concentrated Photovoltaic Thermal (CPVT) as cooling and thermal energy storage mediums to improve PV cell efficiency. This review leads to the current gaps in the research and recommends future work on developing new PCMs, and NePCMs integrated CPV systems for improved performance, life span and economic feasibility

Emergency medicine clerkship curriculum in a high-income developing country: methods for development and application

Abstract Background The published recommendations for international emergency medicine curricula cover the content, but exclude teaching and learning methods, assessment, and evaluation. We aim to provide an overview on available emergency medicine clerkship curricula and report the development and application experience of our own curriculum. Methods Our curriculum is an outcome-based education, enriched by e-learning and various up-to-date pedagogic principles. Results Teaching and learning methods, assessment, and evaluation are described. The theory behind our practice in the light of recent literature is discussed aiming to help other colleagues from developing countries to have a clear map for developing and tailoring their own curricula depending on their needs. The details of our emergency medicine clerkship will serve as an example for developing and developed countries having immature undergraduate emergency medicine clerkship curricula. However, these recommendations will differ in various settings depending on available resources. Conclusions The main concept of curriculum development is to create a curriculum having learning outcomes and content relevant to the local context, and then align the teaching and learning activities, assessments, and evaluations to be in harmony. This may assure favorable educational outcome even in resource limited settings

Team-based learning improves knowledge and retention in an emergency medicine clerkship

Abstract Background Team-based learning (TBL) as an instructional pedagogy is increasingly recognized to improve student engagement, value of teamwork, and performance on standardized assessments when compared to traditional lecture-based instruction. The aim of this study is to compare two educational modalities (TBL and didactic/case discussion) on knowledge-based outcome and student perceptions. Methods Two emergency medicine clerkship academic years were studied. In the first year, all topics were delivered via didactic presentations along with case discussions. In the second year, eight topics were delivered using TBL while three topics were delivered via didactic/case discussions. Final exam marks were compared. Student satisfaction survey was also conducted and analyzed. Results After adjusting for student past performance and exam difficulty, student marks improved in the second year for both TBL and didactic/case discussion topics. The average mark for topics taught via TBL in the second year was significantly higher than the average mark on the same topics taught didactically in the first year by 7.5% (T test, p < 0.001). The marks for topics taught via TBL showed better improvement comparing to topics taught via didactic/case discussion by 2.3% (ANOVA-RM, p = 0.042). Student marks related to TBL topics were significantly higher on the medical exit exam (paired t test, p = 0.007). Student response to TBL survey was positive. Conclusions TBL as part of a blended learning environment facilitated improved knowledge-based performance in an emergency medicine clerkship following end clerkship and medical school exit assessments, suggesting TBL stimulates long-term retention. The high acceptance of TBL among our students suggests a preference of this learning modality to didactic teaching
