Abstract

PT. Sukanda Djaya merupakan distributorproduk frozen dari perusahaan PT. Diamond Cold Storage yangmemproduksi produk seperti susu,yoghurt,daging, dan lainlain. Pendistribusian produk dilakukan pada 25 agen konsumendengan menggunakan empat unit kendaraan bermuatanmasing-masing 6,5 ton. Permasalahan yang terjadi adalahperusahaan tidak memiliki rute tetap untuk mendistribusikanproduk nya, yang berakibat adanya produk return dari agenkonsumen kembali ke depot dikarenakan kualitas produkmenurut saat tiba di agen konsumen. Permasalah tersebutterjadi karena lamanya waktu tempuh dikarenakan tidakadanya rute tetap.Pendistribusian produk frozen menggunakan trukberpendingin juga mempengaruhi konsumsi gas emisi yangdihasilkan, karena truk berpendingin menghasilkan 30% gasemisi CO2 lebih tinggi dibandingkan dengan truk biasa.Pengurangan biaya transportasi dan gas emisi dapat dilakukandengan menentukan rute usulan untuk proses distribusi yangefektif dan efisien. Berdasarkan masalah yang terjadi,dilakukan penentuan rute dengan menggunakan metodealgoritma genetika.Hasil yang diperoleh yaitu dengan adanya rute usulan yangdihasilkan menggunakan metode algoritma genetika terjadiminimasi biaya transportasi sebesar 79,35% dan tidak adanyaproduk return yang dihasilkan karena waktu tempuh setiapkendaraan tidak ada yang melebihi waktu shelf life produkyaitu 120 menit.

Abstract

PPS GHD seluas 3,26 hektare menghasilkan sekitar 1.500 liter sampah dedaunan kering per hari akibat banyaknya pepohonan. Selama ini, pengelolaan dilakukan dengan pembakaran yang menimbulkan emisi karbon dioksida serta gangguan bagi masyarakat sekitar. Kegiatan pengabdian masyarakat ini menawarkan solusi melalui pengolahan dedaunan kering menjadi kompos sebagai alternatif ramah lingkungan dan bernilai ekonomi. Kompos yang dihasilkan dapat digunakan untuk pemeliharaan tanaman di area PPS GHD maupun dipasarkan sebagai pupuk organik, sehingga mengurangi ketergantungan pada pupuk kimia dan mendukung pengelolaan lingkungan berkelanjutan. Implementasi dilakukan dengan penerapan sepuluh unit biokomposter berkapasitas 120 liter serta pelatihan penggunaan biokomposter dan pengembangan model bisnis kompos dan pupuk organik cair. Hasil kegiatan menunjukkan potensi signifikan dalam mengurangi volume sampah sekaligus membuka peluang ekonomi. Ke depan, PPS GHD berperan sebagai fasilitator program pelatihan pengolahan sampah organik dan sebagai penggerak penciptaan lapangan kerja baru di sektor pengelolaan limbah.

Abstract

Waste management poses a critical global challenge, particularly in developing countries. Refuse-Derived Fuel (RDF) offers a promising solution, necessitating holistic sustainability evaluations through Life Cycle Sustainability Assessment (LCSA). Aim: This study aimed to conduct a systematic and bibliometric review mapping trends, analyzing methodologies, identifying barriers, and evaluating strategies concerning LCSA development in RDF life cycles within developing countries. Methodology and results: Employing a Bibliometric-Systematic Literature Review (B-SLR) using Scopus data (2011-2024) and analyzed via VOSviewer and qualitative content analysis, the study identified 22 relevant publications. Findings reveal a fluctuating yet growing publication trend with increasing citations, though international collaboration remains limited despite concentrated productivity. Methodologically, studies predominantly use LCA and LCC, with scarce S-LCA integration; key themes include environmental impacts, waste-to-energy (especially RDF in cement), and circular economy. Implementation faces significant technical, economic, social, and regulatory barriers. Proposed strategies emphasize crucial advancements in infrastructure, process optimization, stakeholder engagement, and robust regulatory frameworks. Conclusion, significance and impact study: The findings confirm that while scholarly interest in LCSA for RDF is increasing, its application is fragmented and hindered by persistent barriers. This research provides a crucial synthesis of evidence-based insights for policymakers and enriches academic understanding of LCSA in alternative waste management. Future work should prioritize developing integrated LCSA methodologies (especially for S-LCA), addressing critical data gaps, conducting holistic case studies, fostering international collaboration, and validating proposed strategies to accelerate sustainable RDF adoption and comprehensive waste management.

Abstract

Climate change is one of the leading causes that threaten life on Earth. Indonesia's efforts to overcome this problem are by signing the COP26 Coal to Clean Power Transition Statement or a statement on the transition from coal energy to clean energy. This commitment to clean energy is targeted to reach net zero emissions by 2060. The company wants to expand its business into the new and renewable energy (EBT) sector. Therefore, before the company develops its business to establish a wood pellet factory, it is necessary first to design the initial business and business feasibility, which includes aspects of feasibility analysis, including market aspects, technical aspects, environmental aspects, financial aspects, and sensitivity analysis to be able to determine whether this business development decision is feasible to run or not. The inflation rate is 3.27%, and the MARR value is 8%. Based on the feasibility calculation on the financial aspect, the establishment of a wood pellet factory is feasible with an NPV of Rp 29,393,458,729, IRR of 44.34%, PBP for 2.28 years, and BCR of 1.29. According to sensitivity analysis, the establishment of this wood pellet factory is sensitive to a decrease in product selling prices by 12.01%, sensitive to an increase in direct raw material costs by 41.57% and sensitive to an increase in raw material supply service costs by 51.46%.
