Potentiality Of Palm Oil Biowaste Withcow Dung And Poultry Litter For Compost Production

Potentiality Of Palm Oil Biowaste Withcow Dung And Poultry Litter For Compost Production / Mohammadtaghi Vakili
Malaysia ialah negara pengeluar minyak sawit utama di dunia. Industri ini menghasilkan banyak jenis biojisim. Penggunan biojisim untuk tujuan tambah nilai seperti pengkomposan perlu diteroka dan diselidik. Sebagai satu matlamat akhir, dengan menggunakan sumber buangan bio yang boleh didapati dengan mudah, kompos yang amat cekap dijangka dapat dihasilkan dari biojisim kelapa sawit dengan keterangan yang tepat mengenai ciri-ciri dan tingkah laku biojisim yang berbeza-beza dengan bilangan kali pengkomposan dan syarat-syarat. Objektif kajian ini ialah untuk belajar kesan sisa ternakan (PL) dan tahi lembu (CD) pada pengkomposan proses sisa bio minyak sawit (POBW) dan menentukan nisbah terbaik bahan-bahan buangan bio minyak sawit dan PL dan CD dalam proses membuat kompos. Bahan-bahan buangan bio minyak sawit (EFB dan pelepah) diadunkan dengan PL dan CD dalam lapan nisbah berbeza dan kandungan lembapan dilaraskan kepada 40% untuk semua rawatan semasa proses membuat kompos. Kandungan tong-tong kompos yang dicampur dengan tepat dan diletakkan di tempat teduh untuk mengaktifkan mekanisme penguraian sehingga 11 minggu. Hasil menunjukkan, pada nisbah 1:3 POBW dan tahi lembu telah menunjukkan nilai optimum bagi nisbah C:N (≤ 25). Kekonduksian elektrik untuk kompos matang ialah 2.83 dSm-1 manakala nilai optimum ialah di bawah 4 dSm-1 dalam percubaan ini. Nilai pH rawatan ini pada akhir proses membuat kompos ialah 7.92. POBW dengan sisa ternakan pada nisbah 1:3 telah menunjukkan C:N kurang daripada (≤ 25) serta SPR untuk kompos matang ialah 3.7 dSm-1 and pH ialah 7.35, yang merupakan paling hampir pH semula jadi. Tahi lembu dan sisa ternakan diadunkan dengan POBW bagi memastikan satu keimbangan nutrien dalam matriks kompos untuk aplikasi lebih lanjut dalam pengeluaran pertanian. _______________________________________________________________________________________________________ Malaysia is the major palm oil producing country in the world. This industry generated many types of biomass including the mesocarp fiber, shell, empty fruit bunch (EFB), oil palm frond (OPF) and oil palm bark (OPB). The application of those biomasses for value-added purposes such as composting needs to be explored and investigated. As an ultimate objective, by using easily available biowaste resources, highly efficient compost is expected to be produced from oil palm biomass with proper elucidation of its characteristics and behavior, varying composting times and conditions. The objective of this study was to evaluate the effect of poultry litter (PL) and cow dung (CD) on composting process of palm oil biowaste (POBW) and to optimize the best ratio of palm oil biowastes and PL and CD in composting process. Palm oil biowastes (EFB and frond) were mixed with PL and CD in eight different ratios and moisture content adjusted to 40% for all treatments during the composting process. The content of compost bins were mixed appropriately and placed in shade for activating decomposition mechanism up to 11 weeks. Results showed that at 1:3 ratio of POBW and cow dung had the optimum qualities of C:N ratio (≤ 25). The electrical conductivity (EC) for mature compost was 2.83 mSm-1 while the optimum value was below 4 mSm-1 in this experimentation. The pH value of this treatment at the end of composting process was 7.92. The POBW with poultry litter at 1:3 ratio showed the C:N ratio was less than ≤25, EC for mature compost was 3.7 mSm-1, and pH value was 7.35. Cow dung and poultry litter addition to POBW was beneficial for ensuring nutrient balance in the compost. Therefore, such compost was suitable for further application in agriculture
