This double-blinded, randomized, controlled study was designed to study the effect of dietary supplementation with red palm oil during pregnancy on maternal and neonatal vitamin A status. A total of 170 women were recruited at 16 to 24 weeks of gestation and randomly assigned to an experimental group that received red palm oil to supply approximately one recommended dietary amount (RDA) (2,400 μg) of β-carotene or to a control group that received an equivalent volume of groundnut oil. The women received the oils for a period of 8 weeks, starting at 26 to 28 weeks of gestation and extending to 34 to 36 weeks of gestation. The mean postintervention (34 to 36 weeks) levels of serum retinol were 1.20 ± 0.22 (SD) μmol/L (95% CI, 1.15–1.25) in women receiving red palm oil and 0.73 ± 0.15 μmol/L (95% CI, 0.69–0.77) in their infants; these levels were significantly higher than those in women receiving groundnut oil (1.07 ± 0.26 μmol/L; 95% CI, 1.01–1.13; p < .01) and their infants (0. 62 ± 0.17 μmol/L; 95% CI, 0.57–0.67; p < .001). A significantly lower proportion of women in the red palm oil group than in the control group had vitamin A deficiency (serum retinol levels < 0.7 μmol/L) after intervention (1.5% vs. 9.7%). The proportion of women having anemia was significantly lower (p < .01) in the red palm oil-supplemented group (80.6%) than in the control group (96.7%). The mean birthweight and gestational age of the infants did not differ significantly between the two groups. An increased risk of low birthweight (p = . 003) and preterm delivery (p = . 000) was observed with decreasing serum retinol levels in the third trimester of pregnancy. These results show that red palm oil supplementation significantly improved maternal and neonatal vitamin A status and reduced the prevalence of maternal anemia. Maternal vitamin A status in the later part of pregnancy is significantly associated with fetal growth and maturation. Hence red palm oil, a rich source of bioavailable vitamin A, could be used as a diet-based approach for improving vitamin A status in pregnancy.

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

Geopolymer Binder

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 effectiveness of using maize starch, warm water, cold water, groundnut oil, palm oil and cold storage [refrigerator] in preserving the quality of eggs was studied. Groundnut oil, palm oil and cold storage were equally effective in preserving the quality of eggs while maize starch, cold water and warm water were found ineffective. The effectiveness of palm oil and groundnut oil was further enhanced when the oil-treated eggs were stored in the refrigerator for four weeks. Treatment with groundnut oil for one minute before storage for four weeks was considered the preferred method of preserving the quality of eggs.

This paper reports the effects of local cooling media (groundnut oil, palm oil, shea butter and air) on the mechanical properties of heat treated mild steel. Tensile test, hardness test and microstructural analysis were carried out on the heat treated and as-purchased specimens. The results show significant differences in the mechanical properties of the heat treated specimens. The hardness profile showed higher values for palm oil-cooled, shea butter-cooled, and the groundnut oil-cooled specimens in an increasing of order respectively when compared with as-purchased specimen with 194.9 VHN, while a decrease in hardness was recorded for the air-cooled specimen. Furthermore, the yield strength and ultimate tensile strength of the heat treated specimens obtained through the tensile test analysis showed an increase in yield strength for the groundnut oil-cooled (464.4 MPa) and the shea butter-cooled (412.9 MPa) specimens, and a decrease in yield strength for the air-cooled (358.3 MPa) and palm oil-cooled (307.7 MPa) specimens when compared with the as-purchased specimens (376.9 MPa). Also, the same trend was observed in the ultimate tensile strength (UTS) of the specimens. In contrast, the ductility improved in air-cooled specimen (40.28) while decreased in the specimen cooled in the media when compared with as-purchased specimens (34.22). Furthermore, microstructural analysis revealed that the groundnut oil-cooled specimens gave a microstructural quality than the other heat treated specimens.

Effect Of Particle Size

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.
