Abstract

Heat exchanger pada proses pengolahan air limbah PT. Andalan Furnindo sering bermasalah. Oleh sebab itu, penulis mencoba untuk memodifikasi desain heat exchanger pada bagian tube, baffle, dan estimasi pressure drop agar mendapat performa yang lebih bagus. Proses pengolahan data dimulai dari memodifikasi dimensi diameter shell, diameter tube, panjang shell, panjang tube, jumlah baffles, jumlah tube dan jenis path aliran fluida. Menghubungkan  korelasi antara parameter dengan modifikasi dimensi yang telah dilakukan agar hasil akhir berupa nilai koefisien perpindahan panas dan pressure drop sesuai yang diinginkan. Hasil perhitungan perancangan dengan  Dsid =1 m; di = 0,02 m; do = 0,025 m; panjang shell dan tube=4,6 m; B=5; Nt=1176 dan path aliran U adalah menghasilkan Uc=683  dan Uf=569 ; =1691,3 Pa; dan =1276,6 Pa. Dengan memodifikasi diameter tube dan shell yang lebih besar dari setelan pabriknya dapat memudahkan proses perawatan unit dalam hal membersihkan kotoran dalam tube maupun dalam shell. Sehingga performanya stabil, umur pemakaian unit lebih lama, dan waktu perawatan selanjutnya terjadwal dengan baik. Heat exchanger in the waste water treatment process of PT. Andalan Furnindo is frequently in trouble. Therefore, the authors try to modify the heat exchanger design on the tube, baffle, and estimated pressure drop in order to get better performance. The data processing starts from modifying the dimensions of shell diameter, tube diameter, shell length, tube length, number of baffles, number of tubes and type of fluid flow path. Linking the correlation between parameters with dimensional modifications that have been done so that the final result is the value of the heat transfer coefficient and pressure drop as desired. The results of design calculations with Dsid =1 m; di = 0,02 m; do = 0,025 m; length of shell and tube = 4.6 m; B=5; Nt=1176 and the flow path U is to produce Uc=683  dan Uf=569 ; =1691,3 Pa; dan =1276,6 Pa. By modifying the tube and shell diameter which is larger than the factory setting, it can facilitate the unit maintenance process in terms of cleaning dirt in the tube and in the shell. So that the performance is stable, the service life of the unit is longer, and the next maintenance time is properly scheduled.

Abstract

The phenomenon of regional head elections (Pilkada) with a single candidate creates tension between the principles of democracy and the concept of siyasah syar'iyyah in Islamic politics. This study aims to analyze the implications of a single candidate in the Regional Elections from the perspective of siyasah syar'iyyah, especially in relation to the principles of justice, deliberation (shura), and the benefit of the people. This study uses a qualitative method with a literature approach to examine the views of scholars and regulations that govern the single-candidate Regional Elections. The results of the study show that this phenomenon occurs due to the dominance of political power, high political costs, and strict candidacy requirements, which lead to limited political competition. In Islam, leaders must be chosen through a fair and transparent process, but in an emergency, a pragmatic approach allows for a single candidate for the sake of government stability. Instead, the idealistic approach emphasizes the importance of healthy deliberation and competition. Therefore, siyasah syar'iyyah offers solutions in the form of increasing political participation, reducing administrative obstacles, and guaranteeing transparency in the election process. In conclusion, single-candidate regional elections can be accepted under certain circumstances, but must still pay attention to the principles of democracy and justice so as not to conflict with the values of siyasah syar'iyyah.

Abstract

Low motivation to learn is often considered as the cause of the low quality of graduates of a tertiary institution. This factor even raises a dilemma, because with low learning motivation, students cannot master learning materials properly, but must graduate for the sake of the continuity of the college. Practices like this are safe and lasting, because the majority of students just want to get a bachelor's degree, and not to master science. Meanwhile, many tertiary institutions apply the concept of customer satisfaction in the world of education, making it easier for students to graduate to be considered as providing satisfaction to their consumers (students). Responding to challenges in the world of education today in community service is able to provide and motivate and how to gain knowledge through information technology. The CRAFT method is a self-image programming method introduced by the psychocybernatic technique. This method is a structured method of controlling the soul and the individual. The CRAFT method consists of Cancel, Replace, Affirmation, Focus and Training. The application of the CRAFT method is accompanied by the Mind Mapping technique. In this technique students are required to determine goals, plans and actions. We also certainly know that the benefits of mind mapping are for teaching and learning. The end result of the CRAFT method is being able to increase enthusiasm for learning through motivation and assistance on how to get good knowledge through information technology.

Abstract

This study aims to map the trends and dynamics of scientific publications in the field of libraries and information in Indonesia during the period 2020–2024. Data were obtained using Publish or Perish software with Google Scholar sources, and analyzed using a quantitative descriptive approach through bibliometric methods. A total of 288 articles were analyzed using Mendeley and VOSviewer software to identify publication patterns, annual distributions, and relationships between keywords through co-word analysis. The results showed a significant increase in publications in 2023, which marked a surge in interest in studies in the field of libraries and information. Visualization with VOSviewer groups research topics into several dominant clusters, including library digitization, transformation of the role of librarians, collection management, and information services. Overlay visualization indicates that the old theme that remains relevant is the role of librarians, while the topics that have developed recently are information services and digital libraries. These findings provide a comprehensive picture of the direction of scientific development in the field of libraries and information in Indonesia and become a strategic foundation for further research development.
