Abstract

Portland cement production is a major contributor to carbon emissions in the construction sector because the high-temperature calcination process produces CO₂ emissions that are nearly equivalent to the mass of cement produced. This study focuses on evaluating the potential of ferric oxide waste material in glass fiber-reinforced concrete as a filler to reduce carbon emissions, making it more environmentally friendly. An experimental method was used with a 1:1 binder-to-aggregate ratio and a constant 3% glass fiber addition. The percentage of ferric oxide replacement in the cement was 0–40%. X-ray fluorescence, X-ray diffraction, particle size distribution analysis, sand gradation testing, and mud content were used to obtain the material data. Tests were also conducted to determine compressive strength, flexural strength, water absorption, and dry and wet bulk density. Based on the results obtained, the addition of ferric oxide improved the mechanical properties of glass fiber-reinforced concrete and added to the aesthetic value of the final product. These findings indicate that the application of Glassfibre Reinforced Concrete is environmentally friendly

Abstract

Greenhouse gas emissions from waste management contribute to climate change, including in higher education institutions. This study aimed to evaluate the potential for carbon emission mitigation from waste management at the Politeknik Perkapalan Negeri Surabaya campus through organic waste composting and inorganic waste recycling using a waste bank system. The application of solid waste generation measurement was combined with the Intergovernmental Panel Climate Change guidelines and SNI 3964:2025. A descriptive quantitative approach was employed, utilizing primary data on solid waste characteristics from selected campus buildings. Baseline emission estimates and mitigation scenarios were used, assuming partial implementation of the 3R program: organic waste composting and recycling. The results indicate that the waste management sector produces approximately 5.44 tons of CO₂ per year, and the proposed emission reductions could reduce emissions by approximately 63%. The findings of this study indicate that integrated waste management has significant potential for reducing carbon emissions and supporting the development of low-carbon campuses aligned with Sustainable Development Goals 12 and 13, despite the methodological limitations related to the assumptions of emission factors and the level of implementation

Abstract

Kebutuhan energi fosil yang semakin meningkat membutuhkan energi alternatif. Limbah biomassa berasal dari limbah organik dan bahannya mudah didapat. Limbah biomassa berupa ampas tebu dan tempurung kelapa dapat dimanfaatkan sebagai energi alternatif berupa biobriket. Penelitian ini bertujuan untuk menganalisis pengaruh komposisi ampas tebu dan tempurung kelapa terhadap nilai kalor yang dihasilkan. Metode yang digunakan dalam pembuatan briket ini adalah eksperimen dengan melakukan proses karbonisasi pada ampas tebu dan tempurung kelapa yang dilanjutkan dengan pengayakan agar ukuran karbon yang dihasilkan homogen. Jenis binder menggunakan tepung tapioka dengan kadar 10% dari berat adonan briket. Analisis nilai kalor yang digunakan yaitu dengan menggunakan bomb calorimeter berdasarkan SNI 01-6235-2000. Untuk mengetahui nilai kalor terbaik, maka digunakan variasi campuran ampas tebu dan tempurung kelapa yaitu variasi 1 adalah 10% : 90%; variasi 2 adalah 20% : 80%; variasi 3 adalah 30% : 70%; variasi 4 adalah 40% : 60%; dan variasi 5 adalah 50% : 50%. Hasil uji menunjukkan briket dari ampas tebu dan tempurung kelapa yang memenuhi standar mutu briket adalah variasi 1 sebesar 8530,36 kal/gr; variasi 2 sebesar 8134,81 kal/gr; dan variasi 3 sebesar 5959,82 kal/gr.

Abstract

Politeknik Perkapalan Negeri Surabaya (PPNS) adalah perguruan tinggi berbasis vokasi yang terus berkembang setiap tahunnya sehingga memungkinkan sampah yang dihasilkan juga semakin bertambah baik itu sampah organik seperti sampah sisa makanan, sampah daun-daun, dan serbuk kayu ataupun sampah non- organik. Pengolahan sampah organik paling sederhana yang dapat dilakukan adalah dengan pengomposan. Proses pengomposan dapat dilakukan secara aerobik dengan menggunakan metode Rotary Drum Composter. Parameter yang ingin diamati adalah pH, suhu, kadar air, dan rasio C/N. Sesuai hasil pengamatan, suhu pH, kadar air dan rasio C/N komposter sebesar; 310C; 7,4; 48,60% dan 14,95. Berdasarkan pengamatan fisik kompos, kompos yang terbentuk berwarna coklat kehitaman, serta bertekstur seperti tanah sesuai dengan spesifikasi kompos SNI 19-7030-2004.
