Ringkasan KTI


According to the World Energy Council, the position of Indonesia's energy security has decreasing recently, in 2016 Indonesia ranked 65th out of 129 countries. One of the factors of this condition is because the easy scarcity of oil and gas fuel supplies which impact on the rising prices on the market.
Contradictory to the fact that Indonesia is a country that has a large potential of alternative energy, such as biomass, which is around 32,654 MWe, one of which can be produced from wood processing waste. It is necessary to take concrete steps to utilize alternative energy with considerable potential resources to solve these problem. One of the provinces that has the potential for wood processing waste is South Sumatra, where its production forests are extensive with the total wood production of 6,128,156 m3 and 8.77% of its volume in the form of sawdust waste.
The utilization of sawdust waste in form of biofuel-pellets (biopellet) as the replacement of Liquefied Petroleum Gas (LPG) is the right choice in solving the issues. The advantages of this biopellet are that the processing is quite simple by utilizing animal feed pellet machines, high calorific value (4,280 kcal / kg), and without adhesives. Sawdust lignin content as a physical binder on the outside of the biopellet surface is caused by the heat generated by the compressive strength and friction force between the rollers on the mold (die) of the pellet machine. The technical reliability of this biopellet has been tested at the Energy Laboratory of State Polytechnic of Sriwijaya as a subject, but has not been implemented into the wider community.
Socialization efforts in attracting the interest and accelerating changes in behavior of people who experience dependence on LPG and switch to biopellet is through 3 (three) approachment methods ; experimental, descriptive, and comparative. Several stages has been carried out in the process of making sawdust biopellet without adhesives that is determining the calorific value by proximate analysis, and comparing it with LPG by water boiling test. One kilogram of biopellet that has been packaged, then socialized to several Micro, Small, and Medium Enterprises (MSMEs) around Palembang.
The socialization carried out was by giving demonstrations and training on the use of biopellet. The combustion test of this biopellet begins with burning paper as an initial ignition, and wait for 3-5 minutes until the flame of the biopellet is evenly distributed and stable. The time needed by biopellet and LPG in boiling one liter of water is not much different, namely 300 seconds and 130 seconds.
The impractical nature of biopellet combustion which requires a longer ignition time is a disadvantage compared to LPG which can be directly used. Therefore, this biopellet fuel is more suitable for the usage of industries that use longer intensity of cooking compared to households that require practicality in cooking activities. If the price range of subsidized LPG (3 kg) in the city of Palembang is Rp. 23,000, 1 LPG (3kg) tube ? 7-8 kg biopellet, and biopellet price is Rp. 2,000 / kg, the costs incurred can be saved as much as Rp. 7,000 per one tube using LPG (3kg).
From the results of the socialization carried out to the MSMEs in Palembang through demonstrations and training, indicated the high interest of prospective users of biopellet. Respondents' enthusiasm was seen through the questions they raised about biopellet, such as: price, fuel availability, availability of biomass stoves, and even a statement of interest in becoming a biopellet distributor. Assuming that only 1% of the 28,766 MSMEs units interest in switching from LPG gas to biopellet, then there are ± 280 units of MSMEs that need biopellet. Every MSMEs needs one LPG (3 kg) / day, equivalent to 7 kg biopellet, meaning that every day 1,960 kg of biopellet is needed (2 tons / day).
Thus it can be believed that biopellet has promising market prospects, so it needs to be followed up and developed towards mass production in Palembang. The diversification of biopellet energy in the long term can help the government agenda, number 7 Sustainable Development Goals (SDGs) Point 7, in ensuring the access to affordable, reliable, sustainable and modern energy for all.
