Abstract

This study aims to show the profile of research trends related to zeolite adsorbent material as a filtration medium in waste treatment. The research method used is a literature study with bibliometric analysis. The articles used are 2018-2023 with a total of 287 articles. Keywords used in PoP software are sewage treatment, adsorbent, and zeolite. Article data was analyzed and obtained using Publish or Perish (PoP) software on the Google Scholar database. The results of the following publication trends are represented in the form of graphical visualizations, which are analyzed using VOSviewer software. The focus of this study is the research trend on the effectiveness of using zeolite adsorbent material as a filtration medium in waste treatment. The implications of this study are (1) This finding will provide an empirical basis for the development of the use of zeolite as an adsorbent material; (2) Traceability of data on trends and updates from research on the use of zeolite as an adsorbent material.

Abstract

Daun teh merupakan bahan baku utama dalam produksi teh hitam, dan kualitas serta karakteristik daun teh memiliki dampak langsung terhadap kualitas akhir dari teh yang dihasilkan. kualitas hasil pengeringan. Daun teh yang dikeringkan harus mempertahankan aroma, rasa, dan kualitas organoleptik yang diharapkan oleh konsumen. Pengeringan yang tidak tepat dapat mengakibatkan kerusakan terhadap karakteristik rasa dan aroma daun teh, yang dapat berdampak negatif pada penjualan dan reputasi merek. Dalam tahap penelitian ini, kajian literatur dilakukan dengan pendekatan yang sistematis, dengan merujuk kepada berbagai sumber yang tersedia dalam berbagai basis data penelitian. Hasil penelitian ini adalah memperlihatkan bahwa penggunaan penukar panas untuk memulihkan panas dapat menghasilkan pengurangan sekitar 33% dari total energi yang diperlukan untuk proses pengeringan, yang pada gilirannya menyumbang hingga 80% dari semua konsumsi energi. Hal ini menunjukkan bahwa pemanfaatan penukar panas merupakan strategi yang sangat efektif, dengan potensi menjadi fokus utama dalam meningkatkan efisiensi energi untuk industri pengolahan teh hitam.

Abstract

The advancement of digital technology has given students broad internet access, yet not all of it is used for academic purposes. Internet use for non-academic activities during lectures is known as cyberloafing, which in this study is related to boredom proneness, defined as an individual's tendency to easily experience boredom. This study aims to determine the relationship between boredom proneness and cyberloafing behavior among university students in Jambi City. This research employed a quantitative correlational approach with a cross-sectional design, involving 197 active undergraduate students in Jambi City aged 18–25 years, selected using an accidental sampling technique, with the criterion of using digital devices in daily lecture activities. Data were collected using two instruments, namely the Boredom Proneness Scale Short-Form (BPS-SF) adapted by Saloom and Veriantari (2021) and the Cyberloafing Scale by Simanjuntak et al. (2019), and were analyzed using the Pearson Product Moment correlation test. The results showed a positive and significant relationship between boredom proneness and cyberloafing (r = 0.466; p < 0.001), with a moderate strength of relationship. These findings indicate that the higher students' tendency to experience boredom, the higher their tendency to engage in cyberloafing behavior during lectures.
