Abstract A commercial field of staked eggplant was used ap-proximately 45 days after transplanting for this trial in the Culican Valley of Sinaloa, Mexico. The field was 100 m wide and approximately 2 km in length, located between 2 fields of corn. The crop had recently been sprayed with endosulfan (Thiodan®). Consequently, relatively few adult whiteflies could be observed although the presence of eggs and young nymphs indicated the likelihood of increasing infestation, and no further applications were made by the grower for the duration of the trial. Experimental design was completely randomized block with 5 treatments and 4 replicates. Beds were 100 m in length running north and south with 1.5 m between centers and 2 rows per bed. Plots were 4 beds wide and 15 m long with 1.5 m between plots (90m2). Three weekly applications were made beginning on 12 Feb with 2 Maruyama™ motorized backpack sprayers equipped with a hand-held boom carrying 2 bronze T-Jet™ D2 hollow cone nozzles containing #45 spinner plates. Each bed was sprayed from both sides with 5 liters per replicate of each treatment, delivering a volume of 60.5 gpa. Each plot was sampled for whitefly adults and immature stages prior to application. A beat pan made of an aluminum cake pan 22.5cm X 32.5 cm painted black and covered with a film of vegetable oil and liquid detergent (9:1) was used to sample adults. Three samples were taken in each plot by beating the pan 10 times against the foliage in the middle 2 rows and counting the whiteflies trapped in the oil mixture. Immatures were sampled by counting all whitefly eggs, small nymphs, large nymphs, and pupae in 4 lensfields of 1.77 cm2 per leaf (3 leaves per plot). Additional samples were taken 3 days after each successive treatment. Small nymphs, large nymphs, and pupae were combined as “immatures” for analysis.

Edible Vegetable Oil

Spent bleaching earth (SBE) which is generated from bleaching process is a valuable industrial waste of edible vegetable oil production because of residual edible vegetable oil absorbed. The residual oil in spent bleaching earth can be recovered and reused for application in the industries such as the production of biodiesel and lubricant. Currently, microwave-assisted extraction (MAE) technique is widely used because this method has a shorter extraction time and less solvent consumption when compared with traditional methods. In this study, MAE combined with solvent reflux was optimized using solvent screening experiments and response surface methodology (RSM) to obtain the highest yield of MAE extraction of residual soybean oil from spent bleaching earth. The extraction yield of residual soybean oil obtained from selected solvent were hexane-ethanol mixture (2:1 v/v, 10.19%) > hexane-ethanol mixture (1:1 v/v, 10.00%) >hexane-ethanol mixture (1:2 v/v, 9.98%) > hexane-ethanol mixture (1:3 v/v, 9.83%) > hexane-ethanol mixture (3:1 v/v, 8.59%) > hexane (8.17%) > acetone (7.73%). The regression coefficient (R-squared = 0.9852) expresses the accuracy of the regression and indicates the relationship between experimental data and predicted result, with high regression coefficient close to 1, which is remarkably desired. The experiment conditions for optimal MAE extraction of residual soybean oil from SBE were hexane-ethanol mixture (2:1 v/v), liquid to solid ratio 15.56:1 mL/g, extraction time 12.22 min, and microwave power 350 W. Under such conditions, the highest predicted value of the extraction yield of residual soybean oil was 10.43%.

The increase in global aviation fuel demand has prompted ICAO to declare neutral carbon growth policy in 2050 by using bio based aviation fuel. The purpose of this study was to simulate the production of non-edible vegetable oil into bioavtur and obtain the most potential nonedible vegetable oil based on yield and conversion to be converted into bioavtur. Three potential sources to be converted into bioavtur are kosambi oil, nyamplung oil and kemiri sunan oil. This research was done by simulating of the hydroprocessing process with process simulator by varying the operating conditions on each raw material. Hydrotreating process was varied at 1-5 MPa pressure and temperature 250°C-350°C. The result showed the operating pressure with the highest conversion and yield are around 4MPa. While the operating temperature with high conversion and yield are above 290°C. Nyamplung oil has overall the largest yield and conversion than other nonedible vegetable oil with average 10% greater conversion and 3,3% greater yield at 2MPa.
