Bertepatan dengan rangkaian peringatan Hari Bangunan Indonesia yang diinisiasi PT Indocement Tunggal Prakarsa Tbk, PT Wijaya Karya Beton Tbk (WIKA Beton) hadir dalam seminar “Sustainability Construction to Build Our Future” di Universitas Mercu Buana (UMB), Jakarta Barat, Rabu (4/11).
Sebagai #ConcretExpert, WIKA Beton terus memperluas edukasi mengenai pembangunan infrastruktur berkelanjutan khususnya kepada generasi muda. Hadir sebagai narasumber mewakili WIKA Beton, Vice President of Engineering, Quality and HSE Division, Festy Ratna Aditama, membagikan wawasan industri di hadapan mahasiswa/i Program Studi Teknik Sipil.
Latar belakang pendidikan teknik sipil yang ditempuhnya selama 5 tahun untuk merengkuh dua gelar akademis menjadi relevansi kehadiran Festy di panggung akademik tersebut. Sinergi yang erat antara dunia industri, akademisi, dan generasi muda ini diharapkan dapat mengakselerasi pembentukan ekosistem konstruksi hijau di Indonesia.
Dalam paparannya yang bertajuk “Green Construction in the Precast Industry”, Festy menyoroti tantangan perubahan iklim di sektor konstruksi. Saat ini, produksi semen sebagai bahan baku utama beton menyumbang sekitar 8 persen dari total emisi karbon dioksida (CO2) global.
Menurutnya, teknologi beton pracetak (precast) menjadi titik balik perubahan karena memindahkan proses pengerjaan dari lapangan ke pabrik yang lebih terkendali.
Melalui rancangan campuran (mix design) serta pemanfaatan material pengganti semen seperti Supplementary Cementitious Materials (SCM) dan fly ash, proses produksi pracetak mampu menekan limbah sekaligus mereduksi emisi karbon secara terukur.
“Green construction bersama beton pracetak tidak hanya sekadar tren, tetapi menjadi solusi nyata untuk membangun infrastruktur yang lebih rendah karbon, lebih efisien, dan tentunya berkelanjutan.”
Di lini operasional, WIKA Beton menerapkan transformasi hijau secara menyeluruh dari hulu ke hilir. Langkah ini meliputi penggunaan energi terbarukan melalui panel surya (PLTS) di atap pabrik, digitalisasi manufaktur, hingga program operasional nirlimbah (non-waste program).
WIKA Beton juga melahirkan berbagai inovasi produk hijau, seperti beton geopolimer tanpa semen (100% non-cement), porous concrete, hingga Concrete Reef Unit untuk restorasi ekosistem pesisir.
Klaim ramah lingkungan oleh perusahaan juga harus dibuktikan melalui data yang terverifikasi. Komitmen tersebut diwujudkan WIKA Beton melalui penerapan Life Cycle Assessment (LCA) serta perolehan sertifikasi internasional Environmental Product Declaration (EPD) untuk produk PC Spun Piles.
Konsistensi ini turut mengantarkan WIKA Beton meraih skor ESG S&P Global sebesar 71/100 dan menempati peringkat pertama nasional di industri material konstruksi.
5 Years of Studying, 1 Day of Teaching, WIKA Beton’s Female Leader Presents on Green Construction
Coinciding with the series of Indonesian Building Day commemorations initiated by PT Indocement Tunggal Prakarsa Tbk, PT Wijaya Karya Beton Tbk (WIKA Beton) attended the “Sustainability Construction to Build Our Future” seminar at Universitas Mercu Buana (UMB), West Jakarta, on Wednesday (4/11).
As a #ConcretExpert, WIKA Beton continues to expand education on sustainable infrastructure development, particularly to the younger generation. Attending as a speaker representing WIKA Beton, Vice President of Engineering, Quality and HSE Division, Festy Ratna Aditama, shared industry insights before the male and female students of the Civil Engineering Study Program.
The civil engineering educational background that she pursued for 5 years to earn two academic degrees underscored the relevance of Festy’s presence on that academic stage. This close synergy between the industry, academia, and the younger generation is expected to accelerate the formation of a green construction ecosystem in Indonesia.
In her presentation titled “Green Construction in the Precast Industry”, Festy highlighted the challenges of climate change in the construction sector. Currently, the production of cement as the primary raw material for concrete accounts for approximately 8 percent of total global carbon dioxide (CO2) emissions.
According to her, precast concrete technology serves as a turning point for change because it shifts the working process from the field to a more controlled factory environment.
Through mix design and the utilization of cement substitute materials such as Supplementary Cementitious Materials (SCM) and fly ash, the precast production process is able to minimize waste while measurably reducing carbon emissions.
“Green construction with precast concrete is not merely a trend, but becomes a real solution to build infrastructure that is lower in carbon, more efficient, and certainly sustainable.”
On the operational line, WIKA Beton implements a comprehensive green transformation from upstream to downstream. This step includes the use of renewable energy through solar panels (PLTS) on factory rooftops, manufacturing digitalization, and a non-waste operational program.
WIKA Beton has also birthed various green product innovations, such as cementless geopolymer concrete (100% non-cement), porous concrete, and Concrete Reef Units for coastal ecosystem restoration.
Eco-friendly claims must be proven through verified data. This commitment is realized by WIKA Beton through the implementation of Life Cycle Assessment (LCA) as well as the attainment of the international Environmental Product Declaration (EPD) certification for its PC Spun Piles product.
This consistency has also led WIKA Beton to achieve an S&P Global ESG score of 71/100 and rank first nationally in the construction materials industry.
