Irigasi tetes adalah sebuah teknik irigasi yang berguna untuk menjaga kelembaban tanah dalam kondisi optimal dengan efisiensi pemakaian air sebesar 90 – 95%, karena dengan menggunakan teknik ini air yang digunakan sangat minimal untuk mengurangi evaporasi, aliran permukaan dan perkolasi, masalah utama dari teknik ini adalah jadwal pemberian air dan jumlah air yang diberikan sebab kebutuhan air setiap tanaman akan berbeda, ide dasarnya adalah membangun sebuah system irigasi tetes otomatis yang mengimplentasikan sensor kelembaban tanah. Sebelum membuat kendali otomatis perlu disiapkan sebuah jaringan irigasi tetes, ukuran emitter dan posisi penempatannya. Sistem otomatis kemudian diuji dalam rumah kaca dan merekam data-data yang diperlukan, setelah dilakukan pengujian dapat disimpulkan bahwa sensor kelembaban tanah memiliki nilai korelasi 99.7% terhadap nilai kelembaban tanah teoritis, nilai efisiensi keseragaman irigasi (Cu) sebesar 96.01%, nilai keseragaman distribusi (SU) sebesar 94.85%, nilai koefisien keseragaman (CU) sebesar 93.01% dan dalam pengujian ini didapatkan bahwa 75% dari tanaman selada yang dipanen memenui standar dari Amazing Farm. Sewaktu sistem otomasi irigasi tetes ini diuji ditemukan pula bahwa sensor kelembaban tanah hanya bekerja baik selama 27 hari karena munculnya karat akibat terpapar oleh air.

The growing global population has led to a surge in waste, which is having an increasing impact on environmental sustainability. One alternative to address this issue is waste recycling. The recycling process involves energy consumption and the use of chemicals, which can potentially result in environmental impacts. This study aims to provide a comprehensive understanding of the application of Life Cycle Assessment (LCA) to measure the environmental impacts of recycled products. It examines research trends and directions through a Systematic Literature Review (SLR) combined with bibliometric analysis using the ScienceDirect database for the period 2021–2026. The literature review focuses on recycled products within the scope of LCA systems and environmental impact methods in Life Cycle Impact Assessment (LCIA). The results of this study indicate that the application of LCA for recycled products is predominantly conducted in the plastic and battery industries. However, further application of LCA to recycled products across all industrial sectors promotes green industry policies and sustainability.

Refuse-Derived Fuel (RDF) has increasingly been explored as an alternative energy source derived from solid waste, offering potential contributions to both energy transition and improved waste management. However, the environmental performance of RDF systems has not been widely examined using comprehensive approaches such as Life Cycle Assessment (LCA) and circular economy frameworks. This study applies a Systematic Literature Review (SLR) combined with bibliometric analysis to identify research trends and thematic developments in RDF studies. A total of 109 Scopus-indexed articles were analyzed using VOSviewer, resulting in nine thematic categories, including fuel characterization, production processes, energy recovery, environmental impact, LCA, circular economy, modeling and simulation, application, and innovation. The findings show that most studies still focus on production and energy recovery, while sustainability oriented topics such as LCA and circular economy remain relatively underexplored.

Peningkatan emisi karbon dioksida (CO₂) dari pembakaran bahan bakar fosil menimbulkan kekhawatiran lingkungan yang signifikan karena kontribusinya terhadap perubahan iklim dan pencemaran udara. Metode penangkapan karbon tradisional seperti Carbon Capture, Utilization and Storage (CCUS) memerlukan biaya investasi dan operasional yang tinggi, sehingga membatasi penerapan teknologi bersih. Penelitian ini mengembangkan teknologi elektrolisis karbon berbiaya rendah dari emisi pembakaran lilin untuk mensintesis asam format (HCOOH) sebagai koagulan berkelanjutan dalam pengolahan karet. Karbon ditangkap pada permukaan kolektor logam dan dikonversi menjadi asam format melalui elektrolisis dalam pelarut air dengan 1% b/v Na₂SO₄ pada tekanan 1 atm dan suhu 26°C. Asam format hasil elektrolisis dikarakterisasi dan diaplikasikan sebagai agen koagulasi dalam pengolahan lateks alam, dibandingkan dengan asam sulfat pekat dan asam format komersial. Hasil menunjukkan bahwa asam format hasil elektrolisis mencapai konsentrasi 15% dengan karakteristik fisikokimia yang sebanding dengan produk komersial. Aplikasi koagulasi menghasilkan karet dengan kadar karet kering sebesar 46,22%, tekstur optimal (2,18 MPa), warna putih kekuningan, dan kadar pengotor 4,63%. Parameter air limbah menunjukkan pH 3,31, COD 1194,60 mg/L, BOD 652,60 mg/L, dan TSS 476,60 mg/L, yang relatif lebih baik dibandingkan koagulan konvensional. Teknologi ini menawarkan solusi inovatif untuk mengubah emisi gas menjadi produk koagulan berkelanjutan, mengurangi ketergantungan pada asam sulfat pekat yang berbahaya, serta menciptakan jalur sirkular untuk produksi karet Ribbed Smoked Sheet (RSS) berkualitas tinggi.

The accelerating threats of climate change and environmental degradation require industries to adopt holistic and integrated solutions that go beyond conventional pollution control. This paper presents a comprehensive analysis of the integration between carbon credit systems and industrial wastewater management, viewed through the lens of chemical engineering and process optimization. It emphasizes how the synergistic deployment of carbon reduction technologies and wastewater treatment innovations can support global climate and water sustainability targets, particularly Sustainable Development Goals (SDGs) 6 (Clean Water and Sanitation), 7 (Affordable and Clean Energy), 9 (Industry, Innovation and Infrastructure), 12 (Responsible Consumption and Production), and 13 (Climate Action). By exploring both technological and policy frameworks—including the Paris Agreement, national emission regulations, and voluntary market mechanisms such as the Gold Standard and Verified Carbon Standard—this study outlines pathways for industries to reduce their greenhouse gas emissions while simultaneously improving water quality, recovering energy and nutrients, and enhancing economic returns through circular resource use. The paper also identifies key challenges in implementation, including verification complexity, regulatory gaps, and financial constraints, and proposes innovations such as modular bioelectrochemical systems, microalgae-based treatment for CO₂ fixation, and blockchain-enabled carbon credit verification. In doing so, it aims to provide a roadmap for climate-resilient and environmentally sound industrial transformation grounded in chemical engineering principles.

Plastic waste problems require management strategies that not only reduce waste volume but also create added value through a waste to value approach. This study aims to analyze research development on waste to value based plastic recycling toward a circular economy using bibliometric analysis and systematic literature review. Data were collected from Scopus using open-access article criteria from 2021 to 2026. A total of 27 articles were analyzed bibliometrically using VOSviewer, while 25 full-text articles were synthesized through SLR. The bibliometric results show that plastic recycling, plastic waste, recycling, and valorization are dominant keywords, while activated carbon, bio-based solvents, 3D printing, and effluent treatment remain potential research areas. The SLR results indicate that plastic waste can be converted into construction materials, composites, monomers, chemicals, energy, membranes, adsorbents, catalysts, and recycled packaging. Future studies should integrate technical, environmental, economic, and regulatory evaluations..
