InfoSAWIT, JAKART – ‘Tra-kos’ is made by knowing the lack of empty husk (for the rest it is written ‘jangkos’) application using rickshaw. By using ‘trakos’, the productivity of ‘jangkos’ application could be twice r three times more than using rickshaw.
The fresh fruit bunch (FFB) is processed in palm oil factory (POF) and would produce some kinds of waste. The waste would be processed too to be re-advantaged. Besides not to pollute the environment, according to Indonesian Sustainable Palm Oil (ISPO), the other goal is that the waste could be as organic fertilizer which could increase the particles and substance in the land for palm oil tree to grow.
One kind of waste is empty husk or ‘jangkos’ (for the rests). Every palm oil company mostly uses ‘jangkos’ as the fertilizer to the trees. Some use it as the additional fertilizer, some substitute it to reduce un-organic fertilizer.
Though it is for good purpose - to fertilize, the application of ‘jangkos’ should be fast and well done. ‘Fast’ means, ‘jangkos’, which has been transported by the dump truck from the POF and collected from the blocks, should be fast applied to every palm oil tree. The longer to pile up the ‘jangkos’, the more horn would be. ‘Well’ means, the dilution in every block should be done in right thickness. The general thickness used is one layer. The thicker pile it is, the more spots to breed horn.
The application of ‘jangkos’ in the immature and mature plantation has different doze. Every company has its consideration to determine the doze. One general standard to use in immature plantation is that 30 tons per hectare. While in the mature plantation, it should be 40 tons per hectare. In general, the ‘jangkos’ would be applied by using rickshaw.
Application Using ‘Tra-Kos’
Using rickshaw to apply it would have basic weakness, such as, it is longer to apply. The rickshaw to load ‘jangkos’ is 50 kilogram in average at once. It can be calculated that to apply ‘jangkos’ from one palm oil tree in the mature plantation within SPH 136 would need 6 rickshaw.
From what we observed when learning the ‘jangkos’ application, it is concluded that it takes some time to take ‘jangkos’ into the block and there is small production. The correlation is that if other side (contractor) applies it, in many cases, the contractor could not do it because of small productivity and expensive payment.
From the analysis based on the observation, there comes helping tools to apply ‘jangkos’ that we call ‘Tra-Kos’. It stands for ‘Troli Aplikasi for Jangkos’ or application trolley for empty husk. ‘Tra-Kos’ is made based on learning the deficiency of applying ‘jangkos’ when using rickshaw. By using ‘Tra-Kos’, the productivity of ‘jangkos’ could be applied twice or even three times better than it using rickshaw.
The advantages of ‘Tra-Kos’ compared to rickshaw are:
The first, ‘Tra-Kos’ could load three times more than rickshaw because ‘Tra-Kos’ is pulled by using the power of shoulder. The human power could burden the capacity in ‘Tra-Kos’ though it is three times heavier.
The second, the area to apply gets wider. For there are more dilution for every ‘jangkos’ in every ‘reit’ by using ‘Tra-Kos’, automatically, there are more hectares to do compared to use rickshaw.
The third, cheaper investment. It is admitted, it is expensive to make ‘Tra-Kos’ rather than making ‘jangkos’. But it would be longer to use. So if the investment is calculated in every month, it would be cheaper than ‘jangkos’.
The fourth, interesting to the contractor. By using this helping tool, there would be 4 to 5 million rupiah per month per man. It is twice more than it using ‘jangkos’. Knowing this income, it is interesting magnet for the contractor to do the application of ‘jangkos’.
