Abstract

An investigation was conducted to analyze and compare the properties of bacterial cellulose (BC) films dried using microwave and air convection heating. Prior to the drying process, 90% of the water content inside the BC pellicles was removed through vacuum filtration. After that, the required drying time was only 3-5 min using microwave heating, 95% shorter than that observed for air convection heating. The properties of the BC sheets were characterized by Fourier transform infrared (FTIR), X-ray diffractometer (XRD), color difference meter, and tensile tester machine. The results showed that the structure of the BC films was the same for the BC films dried by microwave and air convection heating, i.e. cellulose I, as observed from FTIR spectra and XRD diagrams. Moreover, their color (L*, a*, and b* values) and mechanical properties were also almost identical. However, a slightly lower crystallinity and a higher swelling degree were observed for the BC film dried using microwave heating. These results suggest that microwave heating could be an alternative method of drying BC pellicles in order to shorten the processing time and reduce energy consumption when compared to air convection heating.

Abstract

A laboratory scale experiment to study the synthesizing and applicability of ultrafiltration membrane technology from nata de coco to eliminate the color of artificially water waste. The membrane used was cellulose acetate based membrane from nata de coco, composed by soaking of NaOH and acetic acid by concentration of 2% (CA-1) and 4% (CA-2). The Acetate celluloses resulting from acetylation have content of acetyl as much as 45.20 % (CA-1) and 44.80% (CA-2). FTIR’s analysis shows typical group absorption of carbonyl C=O in the number of wave 1755.2 cm-1 (CA-1) and 1752.25 cm-1 (CA-2) and group of Acetyl C-O in number wave of 1232 cm-1 – 1240 cm-1. The performance of Both type of membranes tested by pressure of 2 bar, 4 bar and 6 bar. The result shows, The fluks CA-1 with pure water’s 16,2420 L/m2.jam−32,2452 L/m2.hour and the fluks CA-2 with was 8,1210 L/m2.jam−24,1242 L/m2.hour. The cibacron red was used with artificially water waste concentration 50 ppm, 75 ppm, 100 ppm. The Test Result with artificially waste water, the fluks of the membrane CA-1 was 4,54 L/m2.jam−22,21 L/m2.jam and the permeability of 2,7553 L/m2.jam.bar−3,5657 L/m2.jam.bar with rejects 39,88%−63,89%. The fluks of the membrane CA-2 was 2,39 L/m2.jam −21,50 L/m2.jam and the permeability of 2,3118 L/m2.jam.bar−3,3269 L/m2.jam.bar with rejects 54,32%−90,68%   Abstract in Bahasa Indonesia:  Telah dilakukan percobaan skala laboratorium untuk mensintesis dan mengkaji kemampuan teknologi membran ultafiltrasi dari nata de coco dalam menyisihkan zat warna air limbah artifisial.

Abstract

Sastra adalah suatu bentuk dan hasil karya seni kreatif yang objeknya adalah manusia. Sastra merupakan kata serapan dari bahasa Sanskerta yaitu sastra yang berarti “teks yang mengandung intruksi” atau “pedoman”, dari katadasar sas yang berarti “intruksi” atau “ajaran”. Teks sastra juga tidak hanya teks yang berisikan tentang intruksi ajaran, dalam bahasa Indonesia kata ini biasa digunakan untuk merujuk kepada “Kesusastraan” atau sebuah jenistulisan yang memiliki arti atau keindahan tertentu. Penelitian ini bertujuan untuk menganalisis jenis gaya bahasa pada lirik lagu dalam album For More Than a Feeling karya Jeremy Passion. Penelitian ini dalam menganalisis album menggunakan deskriptif kualitatif dengan menggunakan teknik kepustakaan. Dalam menganalisis Penelitian ini menggunakan teori gaya bahasa yang dikemukakan oleh Gorys Keraf (2009) yang membagi gaya bahasa dalam 37 jenis, dan penulis mengambil 9 gaya bahasa di antaranya; eufemisme, pleonasme, erotesis, hiperbol, persamaan atau simile, metafora, personifikasi, sinkdoke, dan ironi. Hasil penelitian berupa Gaya Bahasa Metafora ditemukan sebanyak 12 kali penggunaan gaya bahasa dengan persentase 25%. Gaya bahasa Erotesis dan Personifikasi berada di urutan kedua gaya bahasa yang mendominasi yaitu ditemukan 8 kali penggunaan dan memiliki persentase 18%.

Abstract

The flipped classroom is an innovative learning approach for teaching English grammar in Understanding Structure courses. The lecturer may provide the students with a PowerPoint or video to watch at home. The grammar principles are then applied in class through discussion, practice, and peer evaluation. With this approach, students are encouraged to learn at their own speed and arrive at class ready for more in-depth discussion. This research approach is a literature review, which entails examining a range of sources, including pertinent research findings and reference books, in order to develop underlying hypotheses. The flipped classroom has been shown to improve students' motivation, foster active engagement, and improve their understanding of grammar principles. Its efficacy, however, depends on having top-notch materials and students taking ownership of completing assignments before class.

Abstract

The Digital Education Counseling for Families held at the Tinta Ilmu Community Learning Center (PKBM) in South Tangerang is an effort to implement digital security for parents and schools to support students’ learning in the digital era. Digital education has become a necessity and an innovative way to align educational traditions with technological developments. The development of digital technology has a significant impact on children’a lives. Esay access to digital devices has the potential to cause various problems, therefore, good guidance and communication between students, schools, and prents are essential. The lack of outreach provided by schools and the lack of initiative from parents to independently seek information regarding current digital education developments are weaknesses that must be addressed immediately to mitigate the negative impacts of the current digitaleducation system. This counseling is expected tohelp parents and teachers collaborate in monitoring learning activities involving the digital world, ensuring protection from unnecessary and potentially harmful content. This is expected to create a safer and more conducive digital education for students.

Abstract-- In the context of rapid technological development, online games have become a global phenomenon dominating the leisure time of children and adolescents. These games, with their engaging and interactive designs, often become an essential part of their daily routines. While many acknowledge the entertainment and social potential of online games, their impact on children's learning motivation and academic achievement remains poorly understood. While quantitative studies have provided data on the relationship between online games and academic outcomes, qualitative methods offer a more in-depth perspective on children's subjective experiences in this context. Qualitative methods, through techniques such as in-depth interviews, focus group discussions, and observation, allow researchers to explore the nuances and complexities of children's experiences with online games. This study aims to explore how online games affect their learning motivation, how they balance their time between gaming and study, and how their perceptions of education may be affected by gaming engagement. With this approach, it is hoped that various factors influencing the relationship between online games and academic achievement can be identified, such as the type of game played, the duration of play, and the social context in which the play occurs.

Abstract

Mobile applications have become a good learning tool. This application involves technology that can be accessed anytime and anywhere. But keep in mind also the progress of science and technology can not be separated from the development, discovery and progress of science in the heyday of Muslims. Islam is very influential in the world and even a great deal of learning is applied to certain methods. The aim of this study was to analyze the mobile learning of the Book of Fiqih in the Islamic Law of the Bulughul Haram by mapping knowledge and evaluation of SUMI (the Usability Measurement Inventory). This study uses a method adopted from KMSLC (Knowledge Management System Life Cycle). The results of this study are mapping knowledge and measuring the quality of a system
