Abstract

Within the ever-evolving scene of instruction, the usage of differentiated learning, an approach planned to cater to assorted student’s needs, has picked up unmistakable quality. This article investigates the challenges experienced by science teachers as they explore the complexities of joining differentiated learning procedures into their classrooms in junior high schools in Palu, Central Sulawesi-Indonesia. A mixed-methods investigative plan, comprising overviews and interviews, was utilized to explore the encounters of science teachers. The quantitative stage uncovered that whereas a critical parcel of teachers grasped differentiated learning, they experienced challenges such as time limitations (80%), substance adjustment (50%), constraints to fitting educating assets (20%), students’ resistance (30%), and inadequately proficient improvement (20%). The subjective stage gives in-depth experiences into these challenges, highlighting the requirement for imaginative procedures, progressing back, and asset accessibility to overcome them. The consideration underscores the significance of tending to these challenges to cultivate a more comprehensive and locks-in science teaching-learning environment that benefits both teachers and students

Abstract

Synthetic dyes such as remazol red are commonly used in the batik process, but their residual waste is a major contributor to water pollution. These effluents can degrade water quality, damage aquatic ecosystems, and pose health risks to humans. This research aims to reduce these problems by using an adsorption method that utilises kapok randu branch as an adsorbent for remazol red dye. Kapok randu branches were pyrolysed at temperatures of 400 °C, 450 °C, and 500 °C. This study aims to measure the ability of biochar from kapok randu branches to adsorb remazol red dye under varying weight, time, and pH conditions. The results showed the characteristics of kapok randu branches biochar include moisture content of 400 °C, 450 °C and 500 °C biochar of kapok randu branches of 5.56 %, 5.01 % and 4.80 %, respectively. The ash content of the 400 °C, 450 °C, and 500 °C kapok randu branch biochar was 5.68 %, 6.66 %, and 7.24 %, respectively. The maximum weight of kapok randu branch biochar in adsorbing remazol red dye is 25 mg with an adsorption capacity of 0.312 mg/g. The maximum contact time required was 60 minutes with an adsorption capacity of 1.004 mg/g. The maximum pH for the remazol red dye during the adsorption process was at pH 4, with an adsorption capacity of 5.816 mg/g.

Abstract

ABSTRAK Desa Silutung sebagai wilayah agraris tropis menghasilkan limbah sekam padi dalam jumlah besar, namun pemanfaatannya masih belum optimal, sehingga tidak hanya berpotensi menimbulkan permasalahan lingkungan, tetapi juga menyebabkan hilangnya peluang untuk mengembangkan limbah tersebut sebagai bahan bangunan ramah lingkungan; oleh karena itu, kegiatan pengabdian ini bertujuan untuk mengkaji efektivitas pelaksanaan seminar dan workshop dalam meningkatkan literasi masyarakat terkait pemanfaatan abu sekam padi sebagai material konstruksi alternatif. Penelitian ini menggunakan pendekatan mixed methods dengan desain explanatory sequential, yang mengombinasikan pengumpulan data kuantitatif melalui pretest dan posttest serta data kualitatif melalui observasi dan wawancara, dengan subjek sebanyak 20 peserta yang terdiri atas kelompok tani, pengrajin, dan siswa. Analisis data dilakukan menggunakan N-Gain dan deskriptif persentase, yang menunjukkan bahwa 65% peserta berada pada kategori peningkatan sedang dan 35% pada kategori tinggi, tanpa adanya peserta dalam kategori rendah, sehingga dapat disimpulkan bahwa kegiatan seminar dan workshop tersebut efektif dalam meningkatkan literasi masyarakat mengenai pemanfaatan abu sekam padi sebagai material konstruksi yang berkelanjutan. Kata Kunci: Abu Sekam Padi, Literasi Sains, Material Ramah Lingkungan,Pemberdayaan Masyarakat.  ABSTRACT Silutung Village as a tropical agricultural area produces large amounts of rice husk waste, but its utilization isstill not optimal, so it not only has the potential to cause environmental problems, but also causes theloss of opportunities to develop this waste as an environmentally friendly building material; therefore, thiscommunity service activity aims to examine the effectiveness of implementing seminars and workshops inincreasing public literacy regarding the use of rice husk ash as an alternative construction material. This studyuses a mixed methods approach with an explanatory sequential design, which combines quantitative datacollection through pretests and posttests and qualitative data through observations and interviews, with 20 participants consisting of farmer groups, craftsmen, and students. Data analysis was carried out using N-Gainand descriptive percentages, which showed that 65% of participants were in the medium improvement category and 35% in the high category, with no participants in the low category, so it can be concluded that the seminar and workshop activities were effective in increasingpublic literacy regarding the use of rice husk ash as a sustainable construction material. Keywords: Rice Husk Ash, Scientific Literacy, Environmentally Friendly Materials, Community Empowerment
