Masalah sampah, khususnya sampah plastik, merupakan isu global yang mendesak dan berdampak signifikan terhadap lingkungan dan kesehatan masyarakat. Di SMKN 4 Kerinci, Kabupaten Kerinci, Provinsi Jambi, sampah plastik dari kemasan makanan dan minuman serta sisa-sisa makanan organik menjadi masalah utama. Plastik yang sulit terurai dapat berubah menjadi mikroplastik, yang berpotensi menjadi racun bagi manusia. Kurangnya kesadaran siswa mengenai dampak sampah, ditambah dengan kebiasaan membuang sampah sembarangan, memperburuk kondisi tersebut. Meskipun ada upaya pengolahan seperti pembuatan kerajinan dari plastik, solusi ini masih terbatas. Penggunaan ecobrick menjadi salah satu solusi potensial. Melalui kegiatan pengabdian ini, diharapkan masalah sampah di sekolah dan masyarakat dapat diatasi, lingkungan menjadi lebih bersih, serta kesadaran dan partisipasi dalam pengelolaan sampah meningkat. Hasil dari kegiatan pengabdian ini dapat dilihat dari respon peserta yang sangat positif serta antusiasme dan keaktifan peserta yang tinggi dalam mengikuti pelatihan. Peserta juga dapat mengatasi dan meminimalisir serta memiliki niatan dalam mengoptimalkan sampah plastik yang ada dilingkungan sekolah dan masyarakat untuk didaur ulang menjadi produk yang memiliki nilai guna.

Pembelajaran dengan model pembelajaran Creative Problem Solving merupakan salah satu cara untuk meningkatkan proses pembelajaran. Namun dalam pemanfaatannya, model pembelajaran Creative Problem Solving masih minim digunakan oleh guru pada proses pembelajaran di sekolah. Pembelajaran dengan pendekatan Creative Problem Solving berusaha mengaitkan konten mata pelajaran dengan situasi dunia nyata dan memotivasi siswa, menghubungkan pengetahuan yang dimiliki dengan kehidupan sehari-hari siswa serta diperkuat dengan peningkatan kreativitas. Ketika dihadapkan dengan situasi masalah, siswa dapat melakukan keterampilan pemecahan masalah untuk memilih dan mengembangkan tanggapannya. Proses belajar tidak hanya dengan cara menghapal tanpa berpikir, karena keterampilan memecahkan masalah memperluas proses berpikir. Penelitian ini menggunakan rancangan percobaan factorial design 2 x 2 dan teknik analisis varian (ANOVA) dua jalur untuk menjawab hipotesis penelitian. Kemudian untuk mengkonfirmasi hasil pengujian hipotesis dilakukan dengan pendekatan mixed method dimana proses pembelajaran dengan model CPS dilakukan triangulasi konkuren untuk memastikan tahapan pembelajaran yang mana yang berkontribusi terhadap hasil belajar. Selanjutnya hasil belajar juga dilakukan triangulasi konkuren untuk mengetahui dampaknya terhadap keberlangsungan keterampilan belajar peserta didik. Percobaan penelitian ini dengan memperhatikan kemungkinan adanya variabel moderator yang mempengaruhi perlakuan (variabel bebas) terhadap hasil (variabel terikat).Berdasarkan hasil penelitian yang dilakukan model Creative Problem Solving berpengaruh secara signifikan terhadap kemampuan berpikir kreatif peserta didik pada materi redoks (sig = 0,001 < 0.05). Self efficacy peserta didik berpengaruh secara signifikan terhadap kemampuan berpikir kreatif peserta didik pada materi redoks (sig = 0,001 < 0.05). Kemudian terdapat interaksi antara model Creative Problem Solving dan self efficacy terhadap kemampuan berpikir kreatif peserta didik pada materi redoks (sig = 0,027 < 0.05).

This study aims to evaluate the effectiveness of Remazol batik wastewater treatment at SMAN 3 Muaro Jambi through degradation and adsorption using a TiO₂/biochar photocatalytic composite. The biochar was derived from cassava peel and employed under UV light irradiation, with UV-Vis spectrophotometry used for analysis. Treatment efficiency was assessed by varying the biochar mass (1–4 grams) and reaction time (1, 3, and 6 hours). The highest removal efficiency of 100% was achieved at 4 grams of biochar and 6 hours of exposure. The adsorption process followed the Freundlich isotherm model, indicating a multilayer adsorption mechanism on the biochar surface. These findings suggest that the TiO₂/biochar composite offers an effective, eco-friendly, and practical solution for small-scale batik wastewater treatment, particularly in educational and home industry settings.

This study aims to improve students' literacy on greenhouse gas mitigation through a biochar-making project from school organic waste. This study uses a qualitative descriptive approach with a project-based learning model. The study was conducted at SMP Negeri 7 Muaro Jambi with 30 class VII G students as subjects. Data were obtained through observation, interviews, questionnaires, and documentation. The project was carried out by actively involving students in the biochar-making process, starting from waste collection, the pyrolysis process, to analyzing the benefits of biochar. The results showed that student involvement in the project significantly increased their understanding of greenhouse gases, their impacts, and mitigation solutions through biochar. Students were able to explain the concept of GHG, mention its negative impacts, understand the biochar-making process, and demonstrate an attitude of caring for the environment. In addition, teachers responded positively to the project and planned to integrate it into P5RA activities. Thus, the biochar production project has proven to be an effective method in improving students' literacy on GHG mitigation and can be used as an alternative for contextual learning based on the environment in schools.

Coffee husk waste has the potential to cause environmental problems if not properly managed. One promising utilization approach is its conversion into biochar. In this study, biochar was produced via pyrolysis at temperatures of 400 °C, 500 °C, and 600 °C. The final temperature was maintained for 1 hour, after which the material was synthesized using ferric chloride hexahydrate (FeCl₃·6H₂O) as an iron precursor through a base precipitation reaction in 1.5 M NaOH solution at 80 °C for 4 hours. SEM–EDX characterization results showed that increasing the pyrolysis temperature influenced pore structure development, where higher temperatures led to smaller pore diameters and denser surface morphology after Fe incorporation. The highest Fe content was obtained in biochar produced at 600 °C, reaching 14.32%. The utilization of coffee husk waste as a precursor for Fe-modified biochar demonstrates potential for enhancing Dissolved Organic Carbon stabilization. This potential is attributed to the material characteristics obtained, namely the combination of a porous structure and the presence of active iron phases, which theoretically can enhance chemical interactions and binding capacity toward dissolved organic compounds.

Air pollution, particularly particles with diameter of less or equal than 2.5 micrometers (PM2.5), has become important global health and environmental problem. Jambi City in Sumatra is highly susceptible to this issue, both locally and particularly influenced by forest fires. As early studies were conducted over a short period, this study examined the meteorological factors that influenced PM2.5 levels and estimated the pollutant transport pathways over two years in the post-COVID-19 period (2023-2024). The methods employed were time-series analysis, scatter-plot evaluation, multiple linear regression analysis, and backward trajectory modeling using HYSPLIT. The results show that the average PM2.5 concentration in 2023 (30.53 µg/m³) was higher than in 2024 (25.36 µg/m³), with night-time levels generally exceeding day-time levels. 3.69% of the days exceeded Indonesia’s daily air quality standard, while 90.83% surpassed the stricter WHO guideline. Meteorological factors explained only 23–38% of PM2.5, with temperature positively correlated, wind speed showing mixed effects, and humidity and rainfall negatively correlated.. The major PM₂.₅ sources influenced by the southeast–South Sumatra, particularly South Sumatra, highlighting the strong stimulus of transboundary emissions alongside local sources. In the future, studies focusing on chemistry-based source apportionment are needed to accurately separate each contributing source.
