This researchs aims to to find out about the potential of palm oil as a raw material of foam firefighting peat fires in Indonesia.By using the method of literature approach to previous researchers, can be in the know that the vegetable raw materials with thepotential to be developed in Indonesia as a raw material of foam extinguishing peat fires is palm oil. In addition to theavailability of environmentally friendly palm oil is also guaranteed and sustained since 2015, Indonesia produced palm oil andits derivatives amounted to 32.5 million tons, to meet the domestic demand of 18.77% while exports amounted to 81.23%..Utilization of palm oil as a raw material foam fire extinguisher is one form of support to the Indonesian government in order toincrease the downstream and value-added palm oil products as well as reduce the level of risk of peat fires

Construction of structures on soft soil is a challenging task and considered as one of the biggest concerns in geotechnical engineering. Binders that are environmentally friendly such as fly ash based geopolymer have been explored widely. In this study, the agro-waste material, Palm Oil Fuel Ash (POFA) was used to produce an environmentally friendly geopolymer binder to be used in soft soil stabilization. POFA was used in three ratios; 10%, 20% and 30% of dry weight of soil to produce geopolymer. Sodium hydroxide (NaOH) was used as an alkali activator at 12 molarity along with sodium silicate (Na2SiO3). Physical properties of soil (Atterberg Limits, Plasticity Index, and Linear Shrinkage Limit) and compaction assessment; before and after mixing with the geopolymer binder were investigated. The studied soil was classified as an inorganic high plasticity silt (MH), according to the Unified Soil Classification System (USCS). From compaction results; optimum moisture content (OMC) values showed a decreased pattern from 24.7% to 17.5%; and maximum dry density (MDD) increased from 1.37 Mg/m3 to 1.73 Mg/m3 for geopolymer with POFA ranging from 0% to 30% of the dry weight of soil, respectively. The optimum dosage of POFA based geopolymer was found to be 30% according to all tests mentioned. These properties suggest the potential use of the agro-waste based geopolymer binder to stabilize the soft soil.

The abundance of empty fruit bunches (EFB) is a result of many palm oil industries increasing their crude palm oil production. Composting is a good, environmentally friendly alternative to overcome EFB. Two different ratios of EFB with biosludge of pulp and paper of 1 : 1 and 3 : 2, respectively, were used in this composting. The particle size of EFB was set into three different sizes of 0.5; 1.5 and 2.5 cm. The best treatment that was obtained from this study was SR4 where the EFB particle size was 1.5 cm, and the ratio between EFB and biosludge of pulp and paper was 3 : 2, respectively. The nitrogen value of SR4 increased from 1.41% to 2.71%, and C/N ratio decreased from 36.74 to 12.17 in 90 days. The population peak of bacteria of SR4 in the thermopilic phase achieved about 33.67 x 1010 cfu/g. These two treatment combinations had shown an increase in EFB composting efficiency.

The development of bio degreaser made from palm oil surfactant aims to substitute bio degreaser made from petroleum surfactant which is less environmentally friendly. The development was carried out by formulating palm methyl ester sulfonate (MES) surfactant with oxalic acid as metal or non-metal cleaning agent. The purpose of this study was to obtain the best concentration of oxalic acid in the bio degreaser formulation. The concentrations of oxalic acid tested were 7, 8, and 9%. The best concentration of oxalic acid was determined based on the results of characteristic tests and detergency tests, namely 7% oxalic acid concentration. The resulting bio degreaser product has a pH of 1.6; viscosity 1.39 cp; specific gravity of 1.012; surface tension 32 dyne/cm and detergency power 84%. Furthermore, the resulting bio degreaser was added with Diethanolamioda (DEA) surfactant. The purpose of adding DEA surfactant is to increase the pH and lower the surface tension. The formulation results showed an increase in pH from 1.6 to 3.2 and a decrease in surface tension from 31.97 dyne/cm to 28.70 dyne/cm. In addition, there was an increase in viscosity from 1.39 cp to 1.62 cp and specific gravity from 1.012 to 1.018.
