Abstract

Abstract Heat exchanger is a device used to transfer thermal energy between two or more fluids at different temperatures. This study aims to develop an efficient shell and tube heat exchanger design that is accompanied by an increase in the overall heat transfer coefficient on the shell and tube sides simultaneously. This study focuses on the impact of using helical baffles and twisted tape inserts technology on the total heat transfer coefficient (U) and pressure drop (ΔP). This study analyzes the effect of employing helical baffles on the shell side and twisted tape inserts on the tube side, with optimization using the Genetic Algorithm (GA) method. The independent variables considered include the helical baffles angle (β), the spacing between baffles (Lbc), the thickness of the twisted tape (δ), and the half-pitch of the twisted tape (H). The optimization objective function for both the shell side and tube side is to maximize the overall heat transfer coefficient, while the restriction is that the pressure drop must not surpass the starting design data value. In this study, the E-1-06 heat exchanger was successfully modeled. The modeling data showed only slight differences between the modeling results and the initial data sheet. The deviation value of the overrall heat transfer coefficient (U) = 0.06%, ∆Ps = 0.00%, and ∆Pt = 0.06%. Optimization of the E-1-06 heat exchanger was also successful. Optimization in this study was able to increase the U value by 3.97%, while the ∆Ps value decreased by -2.01% and ∆Pt by -19.11%. The findings indicate that the modified design is capable of enhancing thermal performance without compromising hydraulic efficiency, thereby demonstrating its potential for application in energy processing systems and industrial cooling.AbstrakHeat exchanger adalah perangkat yang digunakan untuk menyalurkan energi termal antara dua atau lebih fluida pada suhu yang berbeda-beda. Penelitian ini bertujuan untuk mengembangkan desain heat exchanger shell dan tube yang efesien yang disertai dengan peningkatan koefisien perpindahan kalor secara keseluruhan pada sisi shell dan tube secara bersamaan. Penelitian ini berfokus pada dampak penggunaan teknologi helical baffles dan twisted tape insert pada koefisien perpindahan kalor total (U) dan penurunan tekanan/ Pressure drop (ΔP). Pada awalnya heat exchanger ini menggunakan teknologi segmental baffle pada sisi shell dan plain tube pada sisi tube, kemudian desainnya dimodifikasi dengan teknologi yang berbeda, desain pada sisi shell digunakan teknologi helical baffle sedangkan pada sisi tube digunakan teknologi twisted tape. Metode optimisasi yang digunakan adalah Genetic Algoritm (GA). Variabel bebas yang digunakan untuk melakukan optimisasi pada sisi shell adalah sudut helical baffle (ß) dan jarak antar baffle (Lbc) yang ada dalam heat exchanger. Sedangkan variabel bebas yang digunakan pada sisi tube adalah thickness of twisted tape (?), dan half pitch of twisted tape (H). Fungsi tujuan (objective function) optimisasi pada sisi shell dan sisi tube yaitu koefisien perpindahan panas secara keseluruhan (overrall heat transfer coefficient) yang maksimal dan constraint pada optimisasi ini yaitu penurunan tekanan (pressure drop) yang besar nilainya tidak boleh melampaui nilai dari data awal design. Pada penelitian ini heat exchanger E-1-06 berhasil dimodelkan. Data permodelan menunjukkan hanya sedikit perbedaan antara hasil permodelan dengan data sheet awal. Nilai deviasi overrall heat transfer coefficient (U) = 0.06%, ∆Ps=0.00%, dan ∆Pt= 0.06%. Optimisasi Heat exchanger E-1-06 juga berhasil dilakukan. Optimisasi pada penelitian ini mampu menaikan nilai U sebesar 3.97%, sementara nilai ∆Ps mengalami penurunan sebesar -2.01% dan ∆Pt sebesar -19.11%.

Abstract

Bay 'urbun, otherwise known as buying and selling with an advance payment system. In the Al-Qur'an and Hadith, there is not much explanation regarding the terms of buying and selling with an 'urbun' or down payment system. The Syafi'i school prohibits buying and selling with advance payments, while the Hanbali school allows this system. The purpose of discussing this research is to find out the opinions of the two schools of thought regarding buying and selling of the 'urbun or down payment system and also the istinbath method used in. In this study using the research method library research, which comes from books, scriptures or pure essays. The aim is to provide information that can be researched about individuals, conditions, or other symptoms. The results of the discussion conclude that first, Imam Syafi'i's opinion absolutely does not allow buying and selling using the 'urbun system', besides that it also includes buying and selling that is fasid (damaged) and consumes rights in vain. Second, according to Imam Hanbali, the sale and purchase of the urbun system is permissible because both parties have agreed. Imam Shafi'i uses the hadith of Amr Ibn Syu'aib as the method of istinbath, while the Hambali School da'if it, they prefer hadiths originating from the narrations of Nafi' Ibn Harith and Umar Ibn Khattab as the legal basis.

Abstract

Islamic law represents a whole of things. In the early times, Islamic law is a product of divine revelation, prophetic tradition, and custom. In this respect, Islamic law is not only as God's provision which deny human interest, but also human need to regulate society which undergo the on going process. Therefore, costums and traditions were the organic elements, which shape unity of law. Local knowledge and universal values fundamentally enriched Islamic law. This argument is debatable on account of how what some extent customs and traditions can influence or shape the Islamic law. Indonesia is not an exeption. Talking about Islamic law's position in the context of the Indonesian Legal Pluralism was not easy because it has something to do with the structure of Indonesian socio-cultural and socio political reality. This, in turn, needs the special policy through thought and political action.

Abstract

The development of the Islamic Religious Education (PAI) curriculum in Indonesia faces significant challenges in addressing issues of religious moderation and tolerance within a diverse society. PAI is required not only to emphasize normative aspects but also to foster inclusive, tolerant attitudes and social skills among students to live harmoniously in the global era. The aim of this study is to analyze strategies for developing a PAI curriculum that is responsive to religious moderation, focusing on the integration of moderate Islamic values ​​with multicultural education needs, and to propose an applicable and contextual curriculum model. This study employed a qualitative approach with library research methods, collecting data from relevant literature such as books, journal articles, and educational policies. The findings reveal that a PAI curriculum responsive to religious moderation can serve as a transformative instrument in shaping a generation of Muslims who are inclusive, tolerant, and contributive to social harmony. In conclusion, the PAI curriculum should be designed in a multidisciplinary manner and supported by educational policies and teacher capacity building to ensure effective and sustainable implementation.
