Converting Rubber Plantation into Energy Plantation

The fall of rubber prices was followed by the omission until the logging of the plantations. These rubber plantations become damaged and even bare and provide no benefit and even potentially catastrophic. Farmers and rubber entrepreneurs would want to recover even if it could be better about the condition of their previous income hangs from the rubber. It is very likely to be done if they are willing to do it. One of them is by converting the rubber plantation into an energy plantation. What kind of energy plantation should be sought? The multipurpose energy plantations so it can provide many benefits and respite from various obstacles. For more details about the multipurpose energy plantation, can be read here. Just like the food sector, energy demand is also increasing along with population growth. With Indonesia's population reaching 260 million, energy demand is also very big, especially with export market demand driven by climate improvement efforts by lowering the temperatu…

The Multipurpose Energy Plantation

Experience is the best teacher, so the saying goes. So is the problem of renewable energy, especially biomass-based, some of them are the failure of biodiesel production program from jatropha curcas, as well as bioethanol from cassava and sugarcane which is also tragic because it also failed. We need to review and analyze the root causes of the failure so that the failure is not repeated again. In the jatropha energy plantation for biodiesel feedstocks the productivity of jatropha seeds is small and can not compete with diesel oil in the market. In addition, Jatropha leaves can not be used for livestock feeds, whereas if its woody biomass are harvested for energy sources other than the amount is not much, it will also clearly disturb the productivity of the seeds, as its main product.

While on the production of bioethanol from cassava and sugarcane there was a conflict of interest between food and energy sector. Go to the Qur'an should be a reference and a guide to the problem, wh…

Catching Up the Great Opportunity of OPT Pellet Part 2

The abundance of old palm trunks left only in the palm oil plantations until they become decay after entering the unproductive period is one form of waste or inefficiency in the utilization of natural resources. These palm trunks are very potential to be processed into pellet or oil palm trunk pellets (OPT Pellets) which is currently also an export commodity. In addition, there are also a lot of waste namely oil palm fronds  that are only stacked in the oil palm plantationns to wait its decay. Of course it is also a kind of waste or inefficient use of natural resources as well as the case of the palm trunks above. Why do we let it linger? Let's find a solution to that.
These oil palm fronds can be used as fuel for drying the palm trunk powder before it is made pellet. Yes, the palm trunks should be reduced the size (size reduction stage) into the size of wood powder (sawdust) and then dried and then pelleted. In this way biomass wastes become utilized instead of polluting the env…

Migration From Fossil Based Economy to Bioeconomy

Completing the writings on bioeconomy at Go Biomass, Go Bioeconomy!, the short article below try to sharpen and provide various rules or guidelines and motivations for together  to catch  bioeconomy opportunities in shari'a concept by using the guidance of the Qur'an and Hadith. If in the era of fossil based economy, the oil-rich countries (petro dollars) become prosperous countries with abundant wealth, then in the next era of bioeconomy opportunities to switch to countries that have the most biomass wealth. The biomass of plants and animals will live and flourish well in countries with plenty of water and sun, so these are the best places in the future of bioeconomy. Key points that need to be considered, understood and managed properly include business, economics, agriculture, forestry, livestock, fisheries, food, energy, industry, biochemicals and biomaterials.

Europe launches bioeconomy by 2030. In the energy sector, renewable energy use in RED I (Renewable Energy Directi…

Transmigration For Sheep Grazing In Palm Oil Plantation, Is It Possible?

"It is He Who has sent down rain from the sky for you, partly a drink and partly (fertilizes) the plants, on which you are grazing your cattle. "(QS 16:10)

"Eat and graze your cattle. Verily in that is, there are signs of Allah for those who understand. "(QS 20:54)

"" Every Prophet sent by Allah is shepherded sheep / goats ". His friends asked: "So are you?"; The Messenger of Allah said: "Yes, I herded with the wages of some qirath  from the Mecca inhabitants". (H.R. Bukhari)

Indonesia has around 12 million hectares of palm oil plantations currently, comprising 4.8 million hectares of smallholder plantations, 6.2 million hectares of private plantations and 0.8 million hectares of state plantations. The palm oil plantation requires a number of treatments that can continue to produce especially with the target of producing certain fresh fruit bunches (FFB) per hectare. Moreover, the productivity of FFB in Indonesia in general is also …

Export Pellets Fuel And Soil Fertility

There are some people who worry if bioenergy export especially pellets fuel is done massively so soil fertility will decrease or the soil become damaged. Why are they worried about this? Because the intended pellet fuel is EFB pellets or empty fruit bunches of palm oilpellets . Empty fruit bunch of palm oil as raw material EFB pellet is indeed currently many processed into compost or solid organic fertilizer is used on the palm plantation. If there is no fertilizer or nutrients for the palm oil trees it is true that the fertility of the soil will be damaged. Wastes of palm oil plantations such as midrib and leaves can also be composted but will be even more difficult, because  first, as it requires additional effort to collect them, whereas EFB is produced daily in large quantities in palm oil mills so there is no need to collect them. While midrib and palm leaf is the waste of plantation that spread or scattered in the plantation itself. Second, EFB from palm oil tree have high wate…

Dive Cofiring Market

Cofiring becomes an easy entry point for substitution of coal into wood pellet at pulverized power plant system. The cofiring process can also start from small to large percentage, even can change it to 100% using wood pellet later. All pellets fuel of either wood pellet or agro-waste pellet can be used in this cofiring. Agro-waste pellets can be used in smaller portions than wood pellets, because the content of ash is higher than wood pellets. In addition, the agro-waste pellet or pellet ash content made from agricultural wastes is also high in potassium and silica content which has low melting point. In addition, some agricultural wastes also contain high chlorine which is corrosive to boiler pipes.

South Korea's Southeast Power Co (KOSEP) power plant Yeongheung 5000 MW power station with 6% cofiring with wood pellets does not require any modification at all and requires about 10 million tons of coal with 600,000 tons / year of wood pellets. At a coefficient ratio of 3-10% on pr…
