Abstract

Waste is often considered as something useless and valueless. However, as the world enters a new industrial era, there is a growing awareness that waste has a high economic value. With proper processing, the waste can be recycled and even used as a feedstock for power generators. With a waste production reaching 24,000 tons per day in West Java, waste becomes a sustainable raw material. There are several methods for processing waste, such as Zero Waste Management Technology (Masaro) and Waste-to-Energy Power Plant (WtE). This study aims to compare the performance of Masaro and WtE technologies from their potential and economic impact. Both methods certainly have their advantages and disadvantages in terms of waste reduction capacities, products obtained, and financial benefits. This study reveals that Masaro technology can reduce 100% waste, whereas WtE can only reduce up to 70–97%. Subsequently, Masaro technology offers more diverse products rather than WtE (6 products vs. 3 products). Moreover, the gross profit margin (GPM) shows that Masaro can reach 99.27% while WtE is still in the range of 12.23–25.30%. It can be concluded that Masaro has quite higher potential and economic benefits compared to WtE.

Abstract

The problem of unmanaged waste, especially in West Java, certainly has a negative impact on humans and the environment. Thus, the topic of waste processing has become important recently. There are several well-known waste processing technologies, namely MASARO and TOSS. Both have great potential because they can process waste into valuable products that can be sold. This study aims to compare the performance of waste processing with these two technologies from their economic aspects. The method for economic analysis is derived from the details of the waste processing process from both technologies. On the other hand, the method for economic analysis is carried out using IRR parameter. Potentially, MASARO produces liquid organic fertilizer and feed concentrate, while TOSS produces pellets which can be an alternative use of fuel. This liquid organic fertilizer and feed concentrate give a big economic boost to MASARO. The production process has a scale ranging from 0.6 to 6.4 tons/month. The results of IRR calculation from MASARO were obtained at 96.59%, indicating that this technology is economically feasible. Meanwhile, the waste processing product from TOSS is in the form of pellets with a diameter of 10 mm and a length of between 10-40 mm. The calorific value is in the range of 3000-4000 kcal/kg and the maximum water content is 15%. When compared to coal, these pellets tend to have higher levels of volatile matter and ash, while lower levels of ash and sulfur. The calculation results demonstrate that the economic aspect of TOSS is also interesting because it has an IRR of 46.99%. Finally, the application of both technologies can be beneficial for West Java because MASARO technology in the long term can lead to agrarian and livestock sustainability, while TOSS technology in the long term can replace dependence on coal. Abstrak Permasalahan sampah yang tidak dikelola, terutama di Jawa Barat, tentu berdampak negatif terhadap manusia dan lingkungan. Dengan demikian, topik pengolahan sampah menjadi penting akhir-akhir ini. Ada beberapa teknologi pengolahan sampah yang terkenal yaitu MASARO dan TOSS. Keduanya memiliki potensi yang besar karena dapat mengolah sampah menjadi produk yang dapat dimanfaatkan dan dijual. Penelitian ini bertujuan untuk membandingkan kinerja pengolahan sampah dengan kedua teknologi tersebut dari aspek ekonomi. Metode dalam analisis ekonomi diturunkan dari detail proses pengolahan sampah dari kedua teknologi. Setelah itu, metode untuk analisis ekonomi dilakukan dengan parameter IRR. Secara potensi, MASARO menghasilkan pupuk dan konsentrat pakan organik cair, sedangkan TOSS menghasilkan pelet yang dapat menjadi alternatif penggunaan bahan bakar. Pupuk dan konsentrat pakan organik cair ini mendongkrak keekonomian yang besar pada MASARO. Proses produksinya memiliki skala yang berkisar dari 0,6 sampai 6,4 ton/bulan. Hasil perhitungan IRR dari MASARO diperoleh sebesar 96,59% menggambarkan bahwa teknologi ini amat layak secara ekonomi. Sementara itu, produk pengolahan sampah dari TOSS adalah berupa pelet dengan diameter 10 mm dengan panjang antara 10-40 mm. Nilai kalornya berada di rentang 3000-4000 kkal/kg dan kadar air maksimalnya 15%. Jika dibandingkan dengan batubara, pelet ini cenderung memiliki kadar zat terbang dan abu yang lebih tinggi, sementara kadar abu dan sulfurnya lebih rendah. Hasil perhitungan membuktikan bahwa aspek ekonomi TOSS juga menarik karena memiliki IRR sebesar 46,99%. Pada akhirnya, penerapan kedua teknologi dapat bermanfaat bagi Jawa Barat karena teknologi MASARO dalam jangka panjang dapat mengarah pada keberlanjutan pertanian dan peternakan, sedangkan teknologi TOSS dalam jangka panjang dapat menggantikan ketergantungan pada batubara.

Abstract

Timbulan dan pembuangan sampah plastik menjadi masalah global yang semakin rumit dan perlu diatasi. Studi ini bertujuan untuk melakukan analisis bibliometrik dari penilaian siklus hidup (LCA) tentang sampah plastik. Data dari tahun 2013 hingga 2022 dikumpulkan dari Scopus dan Web of Science. Data yang telah dikumpulkan kemudian digabungkan dan dihapus duplikasinya menggunakan R v.4.2.3 dan R studio v.3.8.6. Setelah itu, data dianalisis dan divisualisasikan dengan bantuan Biblioshiny. Data yang dianalisis meliputi publikasi tahunan artikel ilmiah, kontribusi berdasarkan negara, kata kunci yang relevan berdasarkan peta pohon, pola pertumbuhan penelitian, pengelompokan topik, posisi penelitian berdasarkan peta tematik, dan peta struktur konseptual dalam cakupan kata kunci terkait. Tren publikasi tahunan menunjukkan pertumbuhan substansial dari 30 artikel pada tahun 2013 menjadi 631 artikel pada tahun 2022, yang menandakan kesadaran dan perhatian terhadap permasalahan sampah plastik. Tiongkok, Amerika Serikat, dan Italia memimpin publikasi tahunan sekaligus sebagai negara-negara yang paling banyak dikutip artikel-artikelnya, mengingat status mereka sebagai produsen plastik terbesar di dunia. Kata kunci yang paling relevan dari peta pohon juga ditampilkan adanya integrasi yang kuat antara upaya daur ulang plastik dan LCA dalam pengelolaan dampak lingkungan dengan kata kunci yang menonjol antara lain daur ulang, LCA, pengelolaan sampah, sampah plastik, dampak lingkungan, dan ekonomi sirkular. Studi ini pada akhirnya memberikan wawasan mendalam mengenai posisi penelitian dan arah masa depan terkait studi LCA tentang sampah plastik, yang semakin meningkat karena pentingnya pengelolaan sampah plastik berkelanjutan. Kajian ilmiah dalam bidang ini diharapkan terus berkembang untuk mendukung kesadaran dan komitmen seluruh pemangku kepentingan dalam mengatasi permasalahan sampah plastik di seluruh dunia.   Abstract The generation and disposal of plastic waste become an increasingly complicated global concern that needs to be overcome. This study aims to conduct a bibliometric analysis of life cycle assessment (LCA) studies on plastic waste. Data from 2013 to 2022 were collected from Scopus and Web of Science. Collected data were merged and deduplicated using R v.4.2.3 and R studio v.3.8.6. Afterward, data were analyzed and visualized by Biblioshiny. The analyzed data encompass scientific production output, contributions by country, relevant keywords by tree map, research growth pattern, topic clustering, research position by thematic map, and conceptual structure map within this scope. The annual publications trend denotes a substantial growth from 30 articles in 2013 to 631 articles in 2022, signifying awareness and attention towards plastic waste issues. China, the United States, and Italy have led annual publications as well as the most cited countries, given their status as the world’s largest plastic producers. The most relevant keywords from the tree map also show a strong integration between plastic recycling efforts and LCA in managing the environmental impact with prominent keywords including recycling, LCA, waste management, plastic waste, environmental impact, and circular economy. This study finally provides profound insights into research positions and future direction related to LCA studies on plastic waste, which are escalating at the forefront because of the importance of sustainable plastic waste management. Scientific studies in this domain are expected to continuously grow to support the awareness and commitment of all stakeholders in addressing plastic waste issues worldwide.
