Abstract

This research was conducted to determine the morphology and composition of loose powder. This research used 3 types of MS Glow brand loose powder, namely natural, ivory and oily. Morphological characterization was carried out using a Scanning Electron Microscope (SEM), while composition was carried out using X-Ray Fluorescence (XRF). The morphology of the MS Glow brand loose powder of the ivory, Natural and Oily types is round in shape with the average particle size of each sample A, B and C, namely 62 nm, 48 nm and 47 nm so that it can be classified as nanoparticles. XRF test results show that all samples contain the elements Mg, Al, Si, K, Ti, Fe. All of these elements are contained in the composition of MS Glow brand loose powder. The XRF test also showed that all samples did not contain dangerous elements such as Lead (Pb), mercury (Hg) and Cadmium (Cd) and met BPOM standards.

Abstract

Solar radiation plays an important role in the desalination process due to its abundance in areas with potable water shortage and also occupies an important position in renewable energies due to simplicity of application. Still distiller is viewed by researchers as suitable source of potable water because of low cost of fabrication, easy operation and zero emission technology. Studies by researchers is geared towards exploring new models to enhance the efficiency of solar stills and increase the production rates. The main aspiration of this work is to experiment the effect of incorporating a passive condenser into a modified conventional solar still to enhance daily productivity rate. It has been found that modified passive still distiller coupled with external condenser gives about 11.85% higher production rate as compared to the modified conventional still distiller. Daily and accumulated distillate yield for the still distillers have been studied and analyzed. As a result of the findings, the researchers recommend the sawdust padding around still distillers can maximize productivity leading to efficient water distillation in regions where that require still distiller usage. This recommendation has desired result of enhancing access to potable water in areas with water scarcity and do contribute to sustainable and cost-effective water purification method.

Abstract

The utilization of purple yam flour is expected to enhance the functional value of cookies. This study aims to determine the effect of processing techniques of purple yam flour (Dioscorea alata) on the characteristics of mocaf-based cookies. This study uses a Completely Randomized Design. Complete with treatments of various processing technique for yam flour: P1 (yam tubers are cut, then steamed, sliced, and dried), P2 (yam tubers are sliced, soaked in 1% citric acid for 30 minutes, steamed, and dried), P3 (yam tubers are cut, then soaked in water for 24 hours, sliced, and dried), P4 (yam tubers are cut, steamed, mashed, mixed with mocaf, and dried), and P5 (yam tubers are soaked in 1% citric acid for 30 minutes, steamed, mashed, mixed with mocaf, and dried). The research shows that the processing techniques affect the hedonic quality of color and flavor of the produced cookies. The encapsulation with mocaf able to retain the color of purple but appear to be darker and not preferred by the panelist. Based on the sensory analysis, the selected cookies from treatment P3 was chosen to produce yam-mocaf cookies. This cookie has color values L*, a*, b* of (37.95; 9.30; 2.10), hardness 77.76gF, moisture content 6.75%, ash content 2.22%, fat content 17.28%, protein content 6.81%, fiber content 5.48%, carbohydrate content 66.79%, and anthocyanin content of 47.01 mg/100g.

Abstract

This study investigated the physicochemical and sensory attributes of Okoho(Cissus populnea) and varieties of Ogbono seeds (Irvingia gabonensis and Irvingia wombolu). Okoho root and Ogbono seeds were processed into flours. The flours were used to formulate six samples which were analysed for functional properties, proximate composition, phytochemical composition and sensory attributes. The result of the functional properties of the flour samples showed that the value of the bulk density ranged from 0.65 to 0.95 g/ml, oil absorption capacity (9.23 to 10.53 g/ml), water absorption capacity (0.93 to 10.00 g/ml), swelling index (1.68 to 10.53 g/ml), foam capacity (0.98 to 11.76 g/ml), emulsion capacity (23.77 to 40.33 g/ml), wettability (0.46 to 7.37min/sec), viscosity (3.02 to 3.19 Pa.s ), gelation temperature (39.02 to 80.04 oC), and gelation time (0.43 to 2.30 min/sec. The result of the proximate composition showed that the moisture content ranged from 6.30 to 8.53%, crude protein (8.02 to 20.62%), crude fibre (2.04 to 20. 72%), ether extract (3.34 to 69.68%), ash (2.52 to 3.57%), and carbohydrate (10.24 to 43.65%). For phytochemical composition of the flour samples, the values of phytate ranged from 0.09 to 0.72%, oxalate (0.02 to 2.15%), phenol (0.11 to 10.27 mg/100g), saponin (0.61 to 2.72 mg/100g), steroid (0.01 to 6.16 mg/100g), tannin (0.25 to 1.67 mg/100g), alkaloid (0.87 to 1.72%), and flavonoid (1.16 to 4.87 mg/100g). The result of the sensory evaluation showed that the soup samples were generally acceptable by the consumers The result of this study showed that Okoho root contained the highest vital nutrient and could be used as a substitute for the costly and over-used Ogbono seeds.

Abstract

The presence of pharmaceuticals and dyes in the environment poses significant threats to human health and ecosystems. This study develops a novel Polyaniline/Titanium Dioxide (PAni/TiO₂) nanocomposite photocatalyst for the efficient photodegradation of tetracycline and methylene blue. Characterization techniques, including FTIR, FESEM, EDX, DRS, and TGA, confirmed the successful formation of the nanocomposite. Under UV and visible light irradiation, The optimal condition for maximum tetracycline and methylene blue degradation efficiency was obtained to be 92% and 95%, respectively, with 100 mg  of PAni/TiO2 nanocomposite, 100 ml  of Tetracycline, and pH 7.0 after 120 min of exposure to UV and visible light. Optimum reaction conditions, including catalyst concentration, initial dye concentration, and reaction time, were investigated. This research demonstrates the potential of PAni/TiO₂ nanocomposite as a promising photocatalyst for the degradation of organic pollutants
