Abstract

In the context of vocational education, technicians play a crucial role as partners to teachers in laboratory or workshop settings in schools specializing in machining technology. Despite having received training at their institutions, many technicians lack sufficient competence to optimally support learning activities. This community service initiative aims to enhance the professional competence of technicians in vocational schools through a structured approach. The activity begins with a field study to assess specific needs, followed by the development of a training model that is then reviewed through a Focus Group Discussion (FGD). This training model is designed to provide technicians and laboratory teachers with comprehensive insights into best practices and effective self-development guidelines. The expected outcome is a significant improvement in the competencies of technicians and laboratory teachers in Bandar Lampung.

Abstract

3D printers of the extrusion type, also known as Fused Deposition Modelling (FDM), are widely used to create products from polymer materials in the desired shapes, such as bricks, holders, toys, and so on. The quality of the printed results is significantly influenced by the process parameters that can be adjusted. This study aims to analyze the effect of the line width parameter on the tensile strength of the prints produced using extrusion-type 3D printers. The specimen design follows the ASTM D638 type IV standard, with variations in the line-width printing parameters: 0.3 mm (P1), 0.4 mm (P2), and 0.5 mm (P3). The specimens were printed in PLA. Testing was conducted on 9 specimens, 3 for each line width parameter (P1, P2, P3), using a Universal Testing Machine. The average tensile strength values obtained were 27.97 MPa (P1), 31.61 MPa (P2), and 30.52 MPa (P3). The highest tensile strength was achieved with a line width of 0.4 mm. The results of the study indicate that the line width parameter affects the tensile strength of the printed results. Determining appropriate printing parameters can improve the quality of the printed product.

Abstract

 The advancement of blockchain technology has introduced new digital economic instruments, notably Non-Fungible Tokens (NFTs), which function not only as representations of digital asset ownership but also as investment vehicles with highly volatile values. This development has sparked debates within Islamic law, particularly regarding the presence of gharar (excessive uncertainty) and maisir (speculative gambling) in NFT investment practices. This study examines the legal status of NFT investment from the perspective of ḥadīth-based muʿāmalah and analyzes the extent to which gharar and maisir are inherent in its transactional mechanisms. Employing a qualitative library research approach, this study uses descriptive-analytical methods to examine Prophetic ḥadīths prohibiting gharar and maisir, and contextualizes them within the technical characteristics and transaction structures of NFTs. Data sources include classical ḥadīth collections, ḥadīth commentaries, fiqh al-muʿāmalah literature, and relevant contemporary scholarly works. The findings indicate that NFTs, as digital assets, possess definable objects, ownership clarity, and verifiable delivery through blockchain technology, and therefore do not inherently constitute gharar. However, the use of cryptocurrency, extreme price volatility, and short-term speculative behavior may introduce elements of gharar and maisir if not accompanied by clear valuation, utility, and investment objectives. Consequently, the permissibility of NFT investment cannot be generalized but must be assessed contextually to uphold justice and the protection of wealth (ḥifẓ al-māl).

Abstract

High ambient temperatures in tropical regions contribute to increased energy consumption for indoor cooling systems. One passive thermal control method that can be applied is the use of Phase Change Material (PCM) as a latent heat storage medium. This study aims to analyze the effect of paraffin-aluminum PCM incorporation on the thermal performance of concrete walls through experimental testing. Four concrete wall prototypes with dimensions of 30 cm × 30 cm × 15 cm were prepared, consisting of a control wall without PCM and walls containing PCM layers with thicknesses of 2 cm, 3 cm, and 5 cm. The experiment was conducted under 200-watt lamp radiation for 16 hours, with temperature measurements recorded at three observation points using K-type thermocouples connected to a data logger. The results indicate that the incorporation of PCM reduced the wall surface temperature compared to the control wall. The 2 cm PCM specimen reduced the temperature by 18–22%, while the 3 cm PCM specimen achieved a 24.6% reduction. The best thermal performance was obtained from the 5 cm PCM specimen, with temperature reductions of 26.8% at the upper point, 22.9% at the middle point, and 19.2% at the lower point. Increasing PCM thickness improved the heat storage capacity and enhanced the wall’s ability to suppress surface temperature rise. The paraffin-aluminum PCM combination demonstrates potential as a passive thermal control material for building walls in tropical climates.
