Abstract

The COVID-19 pandemic that hit Indonesia, and even the world, resulted in a very significant impact on all lines, including the world of education, affecting the learning pattern, which was originally face-to-face to online, online learning is not easy. Many obstacles occur, ranging from not having a smartphone to quotas. Based on this background, the researcher revealed the implementation of blended learning to increase the learning effectiveness of MI students. Bustanul Ulum Tunglur.This study uses a naturalistic qualitative approach, because the research is carried out in natural conditions or as it is, and the type of research used is descriptive qualitative research. The results of the study show that: (1) Planning is by a) holding a meeting at the beginning of the school year, b) needs analysis, c) analyzing problems, d) developing existing learning resources, e) learning objectives (blended learning), (2) Implementation By: a) online learning with WhatsApp, learning videos and google classroom, while offline entry face-to-face is limited, b) summarizing materials and hours, face-to-face varies, (3) Evaluation With: a) PAS Odd 2020/2021 using Android ( CBT) grades 3 to 6, while grades 1 and 2 use paper (PBT), b) PAT 2020/2021 by using google forms, c) advantages (blended learning) when holding PAS/PAT, including saving time, saving money, learning is more effective and efficient.

Abstract

Minimizing ship noise and vibrations is crucial due to  potentially severe consequences, such as communication problems, sleep disturbances, stress, and structural damage. To address this, effective dampers are necessary. Many soundproofing materials now utilize natural fiber waste to replace synthetic materials, which are harmful to environment. One underutilized natural fiber is tofu dregs, which contain fibers suitable for sound absorption. This study investigates using tofu dregs as a composite material in sound-dampening applications. Composites are materials engineered from two or more substances with different properties to create a heterogeneous mixture. In this research, sound-dampening composites were developed using tofu dregs combined with carbon black and talc duco. The study found that the composite containing 60 grams of tofu dregs, 60 grams of talc duco, and 50 grams of resin achieved a sound absorption coefficient of α = 0.19. Meanwhile, the composite with 60 grams of tofu dregs, 50 grams of carbon black, and 50 grams of resin achieved a higher sound absorption coefficient of α = 0.24. These results indicate that the tofu dregs and carbon black composite offer superior sound absorption compared to tofu dregs and talc duco composite, demonstrating potential of tofu dregs as an eco-friendly soundproofing material.
