Abstract

The pulp and paper industry produces the remaining bark as solid waste, where this solid waste pile when it rains will produce leachate that seeps into the ground, causing soil and groundwater pollution. This wood waste can be used as activated carbon (adsorbent) for leachate treatment. The research was divided into two stages, namely adsorbent production and leachate treatment. Production of activated carbon from bark (bark) was activated using a solution of NaOH and H2SO4 as an activator, with variations of bark (gr): activator (ml) = 20:100; 50:200; 70:300. The leachate adsorption process used activated carbon with a mass of 2.5 and 5 g for 30, 60 and 120 minutes. The lowest adsorbent water content was 0.87% activated using NaOH, and the lowest ash content 0.79% when activated with H2SO4. This is still in accordance with the SII standard No.0258-88. The best variation occurred when the addition of activated carbon which was activated using 5 grams of H2SO4 for 120 minutes caused the most significant decrease in COD value of 52%, and pH 7.32. From the variations in the activation of activated carbon adsorbents, the activation of acidic solutions is better in leachate treatment.

Abstract

Academic research on religious expression in Indonesia has long emphasized written sources, while it often overlooks oral traditions such as Kalindaqdaq, an oral poetry of the Mandar people that actively conveys Islamic teachings. This research gap appears because previous studies rarely examine how lexicon and metaphor operate linguistically within this tradition. This study therefore examines how Kalindaqdaq constructs religious values by combining philosophical, linguistic, and anthropolo­gical perspectives. This qualitative study analyzes Lontara manuscripts through philological methods, observes Kalindaqdaq performances ethno­g­raphically, and examines recorded performances using content analysis. The metrical analysis shows that performers consistently apply an 8-7-5-7 syllabic pattern in 98% of the verses. The lexical analysis reveals that Arabic theocentric terms account for 45% of the religious vocabulary and undergo systematic phonological adaptation. The meta­phor analysis further demonstrates how conceptual metaphors translate abstract Islamic ideas into concrete Mandar cultural experiences. These findings show that the study contributes methodologically by combining Scheler’s value theory with systematic linguistic analysis of lexical and metaphorical patterns. At the empirical level, the study documents an endangered oral tradition and clarifies how Islamic doctrine interacts with local cultural cognition in Nusantara’s religious oral literature.

Abstract

Penelitian ini bertujuan untuk mengevaluasi efektivitas implementasi perangkat pembelajaran sains berbasis Education for Sustainable Development (ESD) pada materi pencemaran lingkungan di SMPN 2 Bojong. Menggunakan metode penelitian tindakan kelas dengan desain kuasi-eksperimental, 24 siswa kelas VII dibagi menjadi kelompok eksperimen dan kontrol. Hasil menunjukkan peningkatan signifikan dalam literasi sains (26,6 poin) dan keterampilan berpikir kritis (1,7 poin) pada kelompok eksperimen. Selain itu, 87% siswa melaporkan peningkatan kesadaran terhadap lingkungan, dan kualitas proyek kelompok eksperimen dinilai "sangat baik" (68%). Meskipun terdapat tantangan dalam adaptasi awal guru, implementasi ESD berhasil menciptakan pembelajaran yang lebih interaktif dan relevan. Kesimpulannya, perangkat pembelajaran berbasis ESD efektif dalam meningkatkan literasi sains, keterampilan berpikir kritis, dan kesadaran lingkungan siswa, serta memberikan dasar untuk adopsi lebih luas dalam pembelajaran sains di SMP. Berdasarkan temuan ini, direkomendasikan agar sekolah mengintegrasikan perangkat ESD dalam pembelajaran sains untuk memperkuat keterampilan abad 21 pada siswa.
