Abstract

MiFUS® is a tool that can display the patient's infusion condition so that nurses can monitor patients one by one in a short time simultaneously. Several nurses were involved in this study to provide input to the casing. Product design is done at the beginning to know the initial casing design. Next, the manufacture of casing molds is carried out using a 3D printing machine. The results of the 3D printer are used as a Master Mold for the implementation of Rapid Tooling method with Epoxy material. The solution of product development is catalyst ratio analysis on polyester resin to obtain the optimal ratio of properties including shrinkage and strength of the material to withstand mechanical loads. Validation of shrinkage is carried out using 3D Scanning technology to determine the deviation of dimensions in the casing made against CAD data. Meanwhile, to obtain the strength parameters of the material to withstand mechanical loads, tensile testing is carried out. The results of this study are the contribution of design parameters, namely the amount of shrinkage that occurs and the strength parameters of the material to withstand mechanical loads. The Data and information are presented in the form of product prototypes and user analysis feasibility studies.

Abstract

This paper examines the development of Qur'anic exegesis in Indonesia within the context of Islamic reform movements originating from the Middle East, particularly during the early 20th century reformist-modernist era. Through historical-philosophical analysis, this research traces the intellectual networks between Indonesia and Islamic scholarly centers in the Middle East, especially Haramayn and Egypt. The main focus is on the transmission of Muhammad Abduh's thought and its influence on Qur'anic interpretation in Indonesia. This study reveals the dynamics of acceptance of reform ideas among Indonesian Muslims, as well as the contributions of local reformist-modernist figures in developing a more contextual and rational methodology of tafsir. The analysis also includes the evolution of tafsir thought from the classical era to modernity, considering the socio-historical factors that influenced this development. The research findings show significant transformations in the approach to Qur'anic interpretation in Indonesia, reflecting a synthesis between the classical Islamic intellectual tradition and the demands of modernity. This research contributes to a more comprehensive understanding of the dynamics of Islamic thought in Indonesia and its position in the global Islamic intellectual landscape.

Abstract

This journal explores one of the methods of Quranic exegesis, namely tafsir bi al-ra'yi, a method that has been the subject of extensive debate among scholars and involves specific limitations that must be observed when interpreting the Qur'an. Tafsir bi al-ra'yi is an approach that relies on rationality and ijtihad (independent reasoning) in interpreting the Qur'an. It is characterized using intellect to comprehend Quranic verses while considering linguistic context, the reasons for revelation (asbabun nuzul), and the principles of Islamic law (sharia). This method has generated significant discourse within the field of Quranic interpretation, with both supporters and critics. To provide a comprehensive foundation for this discussion, this paper includes an overview of the definition and historical development of tafsir bi al-ra'yi. The aim of this research is to analyze the boundaries, conditions, and principles that must be followed by an interpreter when employing the tafsir bi al-ra'yi method, in order to prevent deviations from the Qur'an's original meaning

Abstract

Machinery applications often generate excessive heat due to friction between cutting tools and work-piece materials. To mitigate heat and friction, the use of coolant is necessary in machining operations. Wet coolant systems risk environmental and health concerns because of their consumption rates and chemical content whose  waste requires recycling, a process that consumes additional energy and contributes to increased carbon emissions. As a sustainable alternative, the Minimum Quantity Lubrication (MQL) method supplies a fine mist of lubricant in minimal volumes, thereby reducing waste while enhancing machining performance. This study aims to develop an Embedded Coolant System (ECS) based on the MQL method for CNC milling machines, ensuring both ease of integration and effective cooling performance. The ECS was designed with a simplified open-loop controller using an Arduino Mega 2560, a peristaltic pump, and air-pressure control to regulate the coolant mist. Initial calibration was conducted to establish the coolant flow-rate equation as a function of motor speed. Experimental validation was carried out using aluminum and ST-37 steel with HSS and carbide tools, comparing conventional air-pressure cooling (APC) and the proposed MQL-ECS. The results demonstrate that the MQL-ECS significantly reduces machining temperatures and improves surface roughness compared with APC. For aluminum, the average temperature decreased by up to 3% from 30.3 oC, while surface roughness improved by 31% from 1.1µm. For ST-37, the temperature decreased by 5.5% from 31.1 oC, and surface roughness improved by 72.74% from 5.96 µm. These findings confirm both the effectiveness and environmental benefits of the proposed system, providing a feasible solution for modern CNC operations.
