Abstract

Plastic products have been an integral part of human lives. However, concerns over plastic pollution have been growing. Thus, alternative practices that allow more sustainable production and consumption pattern are urgently needed. Improving plastic recycling management is one of the solutions to prevent an increase in plastic pollution. This paper aims to uncover the potential of plastic recycling, to define factors that can leverage the expansion of the recycling process, and to evaluate possible measures that can realize such expansion, especially given the limited literature on these topics. Therefore, a four-month study, which involved two months of rigorous primary survey and interview and secondary data collection process to obtain valuable and accountable raw data, was conducted between October 2019–January 2020. The conducted study showed that the urban population in Java Island generated around 189,349 t of plastic waste per month, but only 11.83% of it was collected. The remaining 88.17% was either directly transported to landfills or littered in the environment. Five major plastic types were collected in the recycling stream, namely, rigid PP (25%), film HDPE (20%), rigid PET (20%), rigid HDPE (14%), and film PP (9%) with more than 80% of collected plastic waste originating from waste pickers. The paper highlights the major challenges in improving post-consumer recycling: (i) failure of post-consumer plastic recyclable to meet the quality industrial standard; (ii) limited recycling processes and infrastructure; (iii) low market demand for recycled products.

Abstract

Ekspektasi dan harapan stakeholder terus berubah dan telah mempengaruhi cara pandang perusahaan saat ini. Social License to Operate adalah peluang perusahaan untuk menguatkan hubungan dengan stakeholder, meningkatkan reputasi dan persaingan pasar, dan akses secara berkelanjutan terhadap sumber daya. Tujuan dari penelitian ini adalah untuk meninjau sejauh mana posisi dan penerimaan masyarakat lingkar tambang terhadap eksistensi PT HM hingga saat ini. Penelitian ini berfokus pada penjabaran hasil penerimaan sosial yang diperoleh PT Hengjaya Mineralindo melalui pendekatan kuantitatif deskriptif dan perspektif community acceptance di dalam konsep Social License to Operate. Berdasarkan hasil yang diperoleh melalui survei di dua desa lingkar tambang, maka ditemukan bahwa penerimaan sosial PT Hengjaya Mineralindo adalah 4.08 (high approval), artinya perusahaan telah berhasil memiliki persetujuan yang tinggi dari stakeholder. Penerimaan sosial yang cukup tinggi ini didukung karena adanya komitmen perusahaan untuk terus berupaya memberikan dedikasi dan kinerja secara baik dan berkelanjutan bagi setiap pemangku kepentingan, mulai dari shareholder, karyawan, rekan bisnis, hingga masyarakat lokal lingkar tambang.

Abstract

Indonesia is an archipelagic country with a high level of biodiversity from the sea to the mountains. Likewise, the island of Sulawesi has a variety of endemic flora and fauna with an extraordinary level of endemicity. This rich flora and fauna face various threats that cause ecosystem degradation. This research is intended to review the level of flora and fauna status in the Sulawesi region, especially in the PT Hengjaya Mineralindo mining area in Bungku Pesisir and Bahodopi District, Central Sulawesi. Based on observations in areas with code HA WD 06, HA Pit Central, HA Arboretum 1 and HA Arboretum 2 areas, it was found that some flora and fauna were categorized as being in conservation status by Minister of Environment and Forestry Regulation No. P 106 Concerning Protected Plants and Animals, International Union for Conservation of Nature (IUCN), and the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Thus, the company will always strive to encourage ecological succession to achieve ecosystem stability in the future through sustainable practices.
