A framework for sustainable construction in railway infrastructure projects / Assa Amiril

The delivery process of railway project development is not an easy task as it involves many parties and issues such as huge land use, resources, extensive investment, and long construction time which give great impacts on the environment, economic and social disruption. The concept of sustainable construction in infrastructure projects emerges as a vital approach among the project stakeholders to achieve a balance between environmental, economic and social in infrastructure projects. This is in line with the Malaysia growing need for sustainable construction practices in built infrastructure. Nevertheless, implementation of sustainable construction concept in Malaysian railway projects is still low where ‘status quo‘ of project delivery is ineffective in holistically addressing environmental, social and economic dimensions. One of the reasons is lack of driving factors that enforce construction practitioners to implement sustainable construction. Albeit sustainability indicators, checklists or assessments have been previously identified and prepared, there is still lack of sustainability factors for sustainable construction in railway projects that can guide the construction practitioners to achieve sustainability goals. Consequently, construction practitioners are still facing difficulty of understanding and translating the idea of sustainability approach into projectlevel. Therefore, the aim of this study is to develop a framework for sustainable construction in railway infrastructure projects. Mixed methods of quantitative and qualitative research of data collection were adopted. Empirical data for quantitative research was gathered via questionnaire survey and qualitative data was collected via semi-structured interviews with respondents from client, consultants and contractors involved in railway projects. The data analysis is carried out qualitatively (thematic content analysis utilising ATLAS.ti software) and quantitatively (descriptive and inferential statistical analysis utilising Statistical Package for Social Science (SPSS), Microsoft Excel and Partial-Least Square of Structural Equation Modelling (SEMPLS)). The findings from the research were used to develop a framework for sustainable construction in railway infrastructure projects which was validated to confirm its external validity. The results reveal that stronger government strategy and organizational attentiveness leads to increased sustainable construction practices. Apart from that, integration of 22 sustainability factors in railway project life cycle phase is critically important to achieve sustainable construction in railway project. The findings also signify ten project effectiveness and efficiency indicators that are important to evaluate sustainability of railway infrastructure project performance. Furthermore, the validation feedback showed that the respondents agreed with the proposed framework and it is appropriate for the context of this research and construction industry

Machining performance of vegetable oil with phosphonium- and ammonium-based ionic liquids via MQL technique

Thermo-mechanical loads are the main factor that influences the tool wear and product surfaces during machining processes. Lubrication in metal cutting is an effective medium to reduce frictional forces and wear on the tool-workpiece interfaces. On this regards, the advantages of using refined bio-based metalworking fluids (MWFs) with the presence of low toxic, biocompatible and oil-miscible ionic liquids (ILs) additives ([N1,8,8,8][NTf2] (AIL) & [P6,6,6,14][(iC8)2PO2] (PIL)) at nominal weight concentrations of 1, 5 and 10% are explored during orthogonal cutting of AISI 1045 steel. Accordingly, the lubricants are supplied via minimum quantity lubrication (MQL) technique and comparative studies are conducted against the performance of the neat modified Jatropha-based lubricant (MJO) and commercially available synthetic ester-based MQL cutting fluid (SE). The combination of mist supply of the MJOs during machining have a great impact on cleaner production that eliminates the excessive usage of fluids and supports the utilization of environmentally friendly chemicals. This work extends the application of a minute quantity of fully miscible ILs in polar vegetable-based MWF which proven to provide a significant improvement on the lubrication effect of the MJO. MJOþAIL10% and MJOþPIL1% showed the best cutting performance amongst all lubricant mixtures with reduction of cutting forces and specific cutting energy by 4 to 5%, cutting temperatures by 7 to 10%, friction coefficient by 2 to 3%, tool-chip contact length by 8 to 11%, chip thickness by 22 to 25%, friction angle by 1 to 2% and increased shear angle by 25 to 29% compared to the SE. Besides, the effect of low friction and reduced cutting forces produced lower specific cutting energy that promotes “greener” and more sustainable working environment

The Theological Implication of Oceanography Concept in the Qur'an

The integration of science and the Qur’an, known as scientific exegesis (tafsīr ‘ilmī), has emerged as a crucial interpretative model in response to the division between secular and religious knowledge. This study delves into Qur’anic verses related to oceanography, exploring their theological significance and uncovering numerous benefits of the oceans, including their roles as sources of life, climate regulators, livelihood providers, and transportation channels. Additionally, it identifies a remarkable 38 verses discussing oceanography, with 18 of them emphasizing key theological messages such as the exclusive divinity of God, His role as the Creator and Controller of all, the submission of nature to Him, the vastness of His knowledge, and His undeniable greatness. Ultimately, the Qur’anic concept of oceanography reaffirms the existence of God as the Creator and emphasizes humanity’s responsibility as His creatures and servants, tasked with worshiping and glorifying Him. This fusion of science and the Qur’an offers valuable alternative interpretations that can enhance human understanding

PENDEKATAN KONSTRUKTIVIS-INTERPRETIS (HERMENEUTIK) SEBAGAI METODE PENAFSIRAN

Tulisan ini akan menjelaskan metode pengkajian Al-Qur’an dengan menggunakan metode hermeneutik. Dalam konteks masyarakat kekinian, banyak para pemikir muslim modern yangberpendapat bahwa hermeneutika merupakan keniscayaan. Dengan hermeneutika pendekatan, pemikiran, pemaknaan maupun interpretasi terhadap teks-teks keagamaan bisa lebih dinamis,kontekstual, inklusif, dan relevan dengan masyarakat kekinian. Hermeneutika sebagai suatu bentuk interpretasi telah membawa cara baru untuk memahami ilmu pengetahuan Islam, seperti Tafsir Al-Qur’an. Ada kontroversi dalam penggunaan pendekatan hermeneutis untuk memahami Al-Qur’an. Satu kelompok menolaknya, sementara yang lain menerima kehadiran hermeneutika sebagai salah satu metode yang relevan untuk memahami tafsir al-Quran, meskipun metode ini berasal dari luar khazanah dunia Islam, Hermeneutika diperlukan untuk memahami al-Quran, terutama untuk menyikapi Isu-isu kontemporer yang sebagian besar tidak diselesaikan dalam interpretasi klasik. Para intelektual muslim kontemporer seperti Nashr Hamid Abu Zayd, Fazlur Rahman, Hasan Hanafi dan yang lain membuka kemungkinan untuk menerapkan hermenutika di dalam menafsirkan Al-Qur’an. Pada akhirnya penulis melihat bahwa penggunaan hermeneutika dalam menafsirkan Al-Qur’an mampu menambah dan memperkaya metodologi tafsir, namun penulis juga sepakat bahwa konsep hermeneutika secara utuh tidak bisa diterapkan dalam menafsirkan Al-Qur’an
