Potensi Produksi Rumput Unggul Pakchong Thailand Yang Mempunyai Kandungan Protein Tinggi

loading...



Rumput Napier Hibrida Pakchong memiliki kandungan protein yang tinggi dan jauh lebih tinggi jika dibandingan dengan rumput odot maupun jenis rumput gajah lainnya dan juga merupakan tanaman energi yang menarik. Pakchong telah terbukti menghasilkan energi yang lebih tinggi daripada jenis rumput napier lainnya dan sangat ideal sebagai bahan baku untuk pembangkit listrik tenaga biomassa. Kultur jaringan hibrida ini dikembangkan oleh seorang ilmuwan di Thailand.

Menurut Prof. Dr. Krailas, rumput Napier Pakcong 1 Thailand mempunyai jangka hayat yang lama iaitu lapan hingga sembilan tahun. Rumput tersebut tumbuh dengan akar yang dalam, selain kaya dengan nutrisi. Ketika musim kering, rumput tersebut hanya perlu disiram sekali dalam seminggu, selain amat sesuai untuk dibuat makanan haiwan dalam bentuk silaj.

Daunnya pula kurang berduri yang boleh menyebabkan kegatalan berbanding dengan rumput napier lain. Selain itu, rumput Napier Pakchong 1 Thailand mampu menghasilkan makanan untuk haiwan ternakan antara 450 hingga 600 tan metrik sehektar berbanding dengan rumput napier lain yang hanya mampu menghasilkan antara 275 hingga 350 metrik tan rumput sahaja.

Rumput pakchong 1 dengan protein 16.45 persen, rumput taiwan 13 persen dan rumput odot 11.6 persen. Kapasitas produksi rumput odot mencapai 350ton/ha/tahun,pakchong 1 500ton/ha/tahun dan rumput taiwan mencapai 400ton/ha/tahun.

Prospek Rumput Napier Hibrida Pakchong Sebagai Bahan Bakar Pembangkit Listrik:
Untuk setiap 50 hektar lahan, AET dapat membawa teknologi terbaik untuk memberikan gasifikasi atau membakar Rumput Napier hingga 1 MWe dari jaringan listrik atau daya tangkap. AET merekomendasikan penggunaan gasifier GE India yang canggih, yang dibangun di atas modul 2,8 MWe dengan mesin timbal balik GE Jenbacher atau Waukesha. Proyek penggerak pertama ini akan membutuhkan sekitar 200 hektar untuk setiap sistem gasifier modular, jika lahan ditanam ke Rumput Napier.

Untuk proyek di atas 6 MWe, generator Rankine cycle / back pressure steam turbine generator (STG), akan disukai dari sudut pandang teknis dan keuangan. AET akan bertanggung jawab atas pengembangan proyek pembangkit listrik biomassa dengan pemilik tanah / perkebunan yang bekerja dengan AET untuk membangun sistem bahan baku yang layak untuk memastikan kelangsungan hidup biomassa hilir menjadi pembangkit energi.

Untuk setiap 1.000 hektar yang ditanam ke Napier Grass hybrid, AET akan mengembangkan pembangkit listrik 20 MW. - Untuk perusahaan perkebunan skala besar dengan operasi industri, AET akan mengembangkan proyek untuk memastikan daya tawanan yang cukup untuk mempromosikan swasembada energi dari tanaman Rumput Napier yang ditanam di lahan yang dikontrol oleh perusahaan perkebunan skala besar.

Menumbuhkan Rumput Napier Hibrida Pakchong
Potensi Tanaman Energi - Otoritas pemerintah Thailand mengkonfirmasi bahwa hasil 140 ton Rumput Napier kering tulang per hektar per tahun sangat mungkin. Ini didasarkan pada total panen 570 ton Rumput Napier segar per hektar per tahun. Konten kelembaban adalah 75%; bahan kering rata-rata dikatakan 25%.

Particularly in Central Luzon, AET is encouraging land owners/plantation managers with land availability of at least 200 hectares or more to consider the Pakchong Hybrid Napier Grass as an attractive energy crop. The Pakchong has been proven to yield higher energy than other types of napier grass and is ideal as feedstock for biomass power plants. The tissue culture of these hybrid was developed by a scientist in Thailand.

Pakchong Hybrid Napier Grass Prospects:
For every 50 hectares of land, AET can bring the best technologies to gasify or combust the Napier Grass for up to 1 MWe of grid fed or captive power.  AET recommends the use of state-of-the-art GE India gasifiers, building on a 2.8 MWe module with either GE Jenbacher or Waukesha reciprocating engines. These first mover projects would require about 200 hectares for every modular gasifier system, if land were planted to the Napier Grass. 

For projects above 6 MWe, Rankine cycle / back pressure steam turbine generators (STG), would be favored from technical and financial standpoints.  AET would be responsible for the project development of the biomass power plants with the land owner/plantation working with AET to establish a viable feedstock system to ensure the viability of the downstream biomass to energy power plant.

For every 1,000 hectares planted to the Napier Grass hybrid, AET would develop a 20 MW power plant. -  For  large scale plantation companies with industrial operations, AET would develop the projects to ensure enough captive power to promote energy self sufficiency from the Napier Grass crop planted on lands controlled by the large scale plantation companies.
Project Development Timelines:

For the Plantation – First crop cutting by the end of the 8th month, and then quarterly cuttings thereafter for up to 7 years

For the Biomass Gasifier Power Plant – Approximately 6 months to turnkey operation

For the Biomass Rankine Cycle Boiler /STG Power Plant – 18 months to turnkey operation

 Land Availability Requirements:

Hard title on the land

If the land is tribal, then NCIP endorsement will be required to start the project

Minimum 15-year lease agreement preferably with a local invested partner who can manage local regulatory and cultural issues and preferably with options to extend the lease

Growing the Pakchong Hybrid Napier Grass
Energy Crop Potential – The Thai government authorities confirm that yields of 140 tons of bone dry Napier Grass per hectare per year is very possible.  This is based on a total harvest of 570 tons of fresh Napier Grass per hectare per year. Moisture content is 75%; average dry matter is said to be 25%.
Growth – The average growth for HiCross is about 1 meter per month. The crop can be harvested once a quarter.
Water Requirements/Tolerance – The HiCross has excellent resistance to excessive rains and waterlogging during rainy season.  In Thailand (nursery & test farming) and Cambodia (actual plantation), irrigation is required for 4-5 months per year. When needed, the Napier Grass requires irrigation once every 10 days or a total of 68 cubic meters of irrigation per hectare (at those times of the year only).  The Thai government authorities suggest that spray irrigation works well.
Land Suitability – Wet tropical or sub tropical climate with a minimum of 1,200 mm of rain per year;  no extended monsoon season to enable harvesting to near 365 days per year;  acidic red loam or mildly saline soil;  less than 15o inclines  to allow for maximum mechanization.  Napier Grass appears to be suitable as an alternate crop on traditional sugar cane fields.
Planting – Initially, the crop planted can last for 7 years, prior to replanting with new crops. 
Fertilization – The Pakchong Hybrid Napier Grass has been developed to utilize little to no fertilizer in the first 2 years.  Starting in year 3, the Thai government researchers would expect that fertilizer costs would be about Thai Baht 300/bone dry ton harvested or about Philippine peso 410/bone dry ton.
Infectious Diseases – While possible infectious diseases need to be studied more aggressively in the Philippines, the Thai government researchers state that there are no infectious diseases that can impact the growth of this particular Hybrid Napier Grass.  According to Thai government researchers, there have been no fungus or rust problems on the plantation or on the test farming areas over the course of several years of study and planting
