JAKARTA - PT Semen Indonesia (Persero) Tbk (SIG) together with its business entities continue to strengthen its sustainability commitment in post-mining land management by reclamation and revegation. At the Narogong Factory, West Java, for example, until 2024 SIG through its subsidiary PT Solusi Bangun Indonesia Tbk has reclaimed 109.02 hectares of land after the limestone and clay mines, as well as planted more than 120 thousand trees.
SIG's Corporate Secretary, Vita Mahreyni, said that the post-mining land reclamation and revegation program is a form of the Company's responsibility to preserve the earth by restoring environmental functions and protecting biodiversity. The types of trees planted include teak trees, trambesi, eucalyptus, sengon, mahoni, membau, and jabon.
Our factory in Narogong also cultivates fragrances on land with an area of 0410 ha as part of the Social and Sustainable Impact Mining Reclamation System program. This integrated agricultural-based community empowerment program takes advantage of the advantages of fragrances that are easy to grow in many types of soil, and have economic value for environmental conservation and economic improvement in society," said Vita Mahreyni, in her statement, Tuesday, April 22.
The planting of citronella on the post-mining land of PT Solusi Bangun Indonesia Tbk Narogong Factory, has been carried out since 2020 on the recommendation of Researcher from the Faculty of Forestry and Environment IPB as well as the Director of SEAMEO Biotrop ( Southeast Asian Tropical Biology Research Institute), Irdika Mansur. Based on research results by doing solitary mapping in 2018, fragrant lemongrass is considered effective for planting in post-mining land because it can grow in various conditions of land and easy care. In fact, fragrant lemongrass can also help prevent erosion in the soil.
No less important, citronella plants also have economic value. At the Narogong Factory, the citronella that has been cultivated on post-mining land, is then managed into various processed products of atsiri oil by the Women Aware of Work (PUSAKA) group with the SIJEBI brand since 2021. These products include essential oils, hand sanitizers, carbols, oils for massage, wind oil, telon oil, to hand washing soap.
Proses produksi dilakukan menggunakan fasilitas pengelingan minyak atsiri tipe distilasi vapour dengan kapasitas mesin pengelingan 1.2 ton serai sera sera. Saat ini, kapasitas panen seri serahan di lahan pascatambang PT Solusi Bangun Indonesia Tbk Factory Narogong sendiri berkisar antara 3 - 5 kg per hektare. Tidak berhenti di situ, sampah serai seri seraman dimanfaatkan sebagai feedan sapi untuk program pembelakan sapi di kandang komunal.
The management of post-mining land by planting citronella on the post-mining land of the Narogong Factory involves at least 34 farmers and the people of Ring 1 Company. They are divided into several working groups, ranging from planting, nursery, distillation, to production.
Not only working on local markets in Bogor Regency, SIJEBI atsiri oil processed products have reached the national market through the marketplace. The consumers come from various regions in Indonesia, covering the Jabodetabek area (Jakarta, Bogor, Tangerang and Bekasi), Bandung, East Java, to Kalimantan. In fact, SIJEBI often receives visits from researchers and academics, especially representatives from Filipino researchers from the Southeast Asian Tropical Biology research institute, namely SEAMEO Biotrop.

To expand the market, SIJEBI often participates in various exhibitions, both national and international levels, including the Indonesian MSME Bazaar in Sarinah Jakarta in 2024, the Bazar of the National Conference on Atsiri Oil at the IPB International Convention Center in 2024, and the International Federation of Sport Climbing (IFSC) in Senayan Jakarta in 2023. Adding international exposure, SIG also often introduces SIJEBI products as souvenirs for guests or stakeholders from abroad, to participate in promoting SIJEBI as a result of cultivation from sustainable post-mining programs.
Vita Mahreyni added, in 2024 the PUSAKA group managed to reap revenue from the sale of SIJEBi products reaching Rp227 million, or an increase of 17% from 2023 of Rp193 million. This achievement even increased 490% from the baseline in 2021 of Rp38.41 million, which showed proud growth and proved the Company's success in sustainable post-mining land management.
This program is a breakthrough in post-mining land management, by building a value chain of reclamation activities that have a sustainable social and economic impact. SIG and its business entities are committed to always presenting innovative social and environmental responsibility programs so that the benefits can be directly felt by stakeholders," said Vita Mahreyni.
