Abstract

Higher education has an important role in the Tri Darma, namely participating in truly educating the lives of the nation and state in society. One step is to make humans no longer objects of development but subjects of development. As a development subject, abilities and skills in mastering science and technology are certainly required. The use of welding technology has developed and is widely used and exploited in the wider community, especially in meeting industrial needs. One of the welding methods is Shielded Metal Arc Welding (SMAW), namely welding using an electric arc. The aim of this activity is to increase the welding competency of Bungku Mining Vocational School students by adding special skills in the form of SMAW welding and providing encouragement and assistance so that Bungku Mining Vocational School students are able to provide welding equipment that supports learning in the laboratory. The benefit of this activity is to provide knowledge and train skills in SMAW welding so that it can be used to develop laboratory facilities.

Abstract

Aplikasi baterai ion litium secara komersial telah tersebar luas dan meningkat seiring pertumbuhan penduduk baik di Indonesia maupun Dunia. Baterai ion litium tersusun atas katoda sulfur, separator, anoda logam litium dan elektrolit organik. Separator baterai adalah komponen penting yang berperan dalam pertukaran ion pada saat pengisian dan pemakaian baterai. Beberapa material telah dimodifikasi untuk membantu mencegah katoda berdifusi serta menjaga posisi katoda tersebut agar tetap pada posisinya sehingga mampu meningkatkan kinerja baterai. Peningkatan ion konduksi menjadi hal yang perlu diperhatikan dalam aplikasi pengisian ulang daya baterai litium. Penelitian ini bertujuan membuat bahan membran separator Polyvinylidene Fluoride - Boron Nitride – Hexafluoropropylene dengan metode inversi fasa dan metode pencampuran. Perbandingan variasi penambahan bahan adalah 1 : 2 pada masing-masing metode. Performa membran separator dilihat berdasarkan derajat kristalinitas, ukuran pori, gugus fungsi O-H dan PVdF, serta nilai konduktivitas listrik. Berdasarkan hasil interpretasi dari berbagai analisa tersebut, masing-masing metode memberikan kelebihan dan kekurangan terhadap konsentrasi bahan yang digunakan. Namun, dapat disimpulkan bahwa metode inversi fasa dapat lebih diunggulkan dalam menghasilkan produk yang lebih stabil

Abstract

One of the most practical and economical ways to dissipate large amounts of heat generated by different types of equipment is to use enclosed cooling towers, as cooling towers offer the important advantage of direct contact between liquids. To support the development of new research that makes an important contribution to the topic, it is necessary to analyze research trends. The approach used in this study is a bibliometric analysis of publications indexed in the Scopus database over the last ten decades (1922-2023). In this study, a total of 178 cooling tower publications were evaluated to assess publication production trends, countries, primary languages, institutions, authors, major journals, and keywords. The results showed a fluctuating trend in the number of articles during the period with the main focus on cooling towers. Countries such as China and the United States showed high productivity in this study. Authors such as guan and gurgenci have significant contributions in cooling tower research. Commonly used keywords include cooling tower and cooling tower design.The implications of these findings can help researchers, academics, publishers, and other stakeholders in understanding and optimizing their contributions in the field of study of cooling towers. Thus, this research makes a valuable contribution in enriching the understanding of research developments in the cooling tower domain
