Authors: Liu Siqi 
Published: February 2021

Abstract
With the rapid development of modern urbanization, the unreasonable industrial structure has impacted urban environment, which greatly restricts the use of land resources safely. Especially in some cities with rapid urbanization, on the one hand, urban development requires a large amount of lands; on the other hand, the urban environment exceeds its bearing capacity, and human settlements environment have been negatively affected. Taking the typical urban fringe of Xi’an as the research area, this study detected Cd, Cr, Cu, Ni, Pb and Zn combined with GIS, RS and GPS technologies. Totally 26 sample points were collected. The pollution index method (single pollution index, Nemerow comprehensive pollution index method), geo-accumulation index method and potential ecological risk index method were used to evaluate the results, and the pollution sources were analysed. According to the analysis results, Cd, Pb and Zn existed obviously ecological risks. The Pb pollution of each sample point was quite different. Sample points 1-13 were located in the east of the research area, mainly distributed on both sides of the traffic road. Pb pollution was relatively serious. The average value of Igeo (Pb) reached 4.20, which belongs to strong pollution - extremely strong pollution. The heavy metal pollution of Zn was universal, however, the toxicity response parameter of Zn is low, Tr
i=1, so the ecological risk was not significant. The detection rate of Cd was only 11.5%, but the value was much higher than background value, which should be paid attention to. The results showed that there are different degrees of heavy metal pollution and potential ecological risks in the research area, which supported the safe use of land in urban fringe areas.

Authors: Liu Na , Wei Zhengying , Wei Haoran 
Published: February 2021

Abstract
In order to precisely provide nitrogen, potassium, and phosphorus via irrigation, this study designed a method for their field detection based on photoelectric colorimetry. We determined the maximum UV-vis absorption wavelengths of nitrogen, phosphorus, and potassium solutions mixed with colorimetric reagents and experimentally determined their standard curves. The detection error was less than 5% by error analysis, and thus the method can be used to determine the concentrations of the target elements on site. We also combined the detection of potassium, nitrogen, and phosphorus with intelligent irrigation decision-making to achieve automatic irrigation. The accurate technology that we developed for controlling water-soluble fertilizers can detect the target elements on-site, which improves the controlled performance of accurate irrigation systems through fast and efficient on-site detection.

Abstract
Nowadays there are many fruit ripening agents available in the market, thus, it is important to know the performance of those ripening agents in applications. This research determined the effect of the type of ripening agents and applied concentrations on the physical changed of banana during ripening process. Ethylene, acetylene, and ethephon in three different concentrations of 0, 250, and 500 ppm were investigated in a 3×3 factorial with three replications. Green mature bananas were treated with those ripening agents in closed boxes, after being treated then stored in the open ambient room until they were ripened. Weight loss, soluble solid content, and firmness of the samples were monitored every 12 hours until the samples were ripened. Results indicated that in the three ripening agents, the changes of weight loss, soluble solid content, and firmness followed zero, first, and second order kinetics equations, respectively. In general, the values of constant rate of change for weight loss and firmness increased with the concentration but not for soluble solid content. Statistical analysis indicated that the type of ripening agent significantly affected the k values of weight loss, soluble solid content, and firmness.

Abstract
Chocolate bars usually use cocoa with or without milk as the ingredients. Innovative chocolate was developed in this study by replacing all cocoa solids with three different powders, namely ginger powder, coffee powder, and fruit flavored powder drinks which was combined with the use of cocoa butter substitute to increase the melting point of chocolate. An alternative processing for chocolate (using a melanger) was used in this study. The evaluated physical characteristics of chocolate were moisture content, color, hardness, melting point and particle size. The results showed that the replacement of all cocoa with or without milk solids with three different powders affected the value of moisture content, color, hardness, melting point, and particle size. Moisture content (0.74-1.3%), particle size (50-65 µm), and the color attributes were directly affected by the original color of the ingredients. The use of CBS as a substitute for cocoa butter increased the melting point of chocolate to 38-39 °C and the hardness of chocolate to 19-24 N/mm2.

Abstract
Chocolate is one of food products made from cocoa beans (Theobroma cacao L). The ingredients of chocolate in general are cocoa butter, sugar, and cocoa powder/cocoa mass. However, in this study, cocoa butter substitute (CBS) instead of cocoa butter was used to increase the value of melting point. In addition, stevia and inulin were used to reduce the calorie of chocolate and red velvet was added as flavoring agent. The purpose of this study was to examine the physical properties of red velvet chocolate sweetened with stevia and inulin. The proportion of stevia used were 15%, 30%, and 45%. The physical properties measured were water content, particle size, color (L*, a*, b*), hardness, and melting point. The result showed that the proportion of stevia significantly affected the characteristics of red velvet compound chocolate. The highest proportion of stevia produced chocolate with the lowest moisture content. Chocolate sample had moisture content in the range of 0.93-1.5%. Particle size was inversely proportional to the water content, ranging from 75.01 to 86.64 µm. Color of chocolates was affected by color of the ingredients. The hardness and melting point of red velvet chocolates were influenced by the proportion of stevia.

Abstract
Dark chocolate is one of the most popular chocolates due to its health benefit offered. One of the factors influencing its health effect is the fermentation process prior to the chocolate making. Fermentation change the cocoa bean chemical compound and affected the flavor and antioxidant content. Aside from that, changes in the inner structure of cocoa nib may also occur, resulting in different characteristics of cocoa solids. The aim of this study was to do a preliminary study on the impact of fermentation level (unfermented, half-fermented, and fermented cocoa bean) on the quality attributes of dark chocolate, namely color, glossiness, melting point and particle size. The results showed that fermentation duration influenced the characteristics of chocolate, to some extent. The color of chocolate made from fermented bean exhibited higher L*, C*, h° values than chocolate made from half-fermented and unfermented cocoa bean, consecutively. On the other hand, melting point of chocolate made from unfermented cocoa bean had higher propensity than that of chocolate made from half-fermented and fermented bean. Glossiness and particle size of the chocolates were comparable.

Abstract
Cocoyam (Xanthosoma sagittifolium) from Banjarnegara highland (and then called busil), is less utilized as a starch source even though it is easily found and locally used as a snack. The objective of this study was to determine the physicochemical properties and recommends suitable utilization of busil starch. This research was conducted in two steps, the first step was busil starch extraction, and the second was the physicochemical characterization and utilization recommendations. Busil had 14% yield of starch, contained 15.4% amylose, and 81.5% amylopectin with 88.1% of whiteness index. Scanning electron microscopy (SEM) showed that they are mostly round, and the granule size was about 11.8 μm. Rapid Visco Analyzer (RVA) analysis showed that busil starch had 74.3°C on pasting temperature. X-ray diffraction (XRD) studies showed that busil starch exhibited an A-type diffraction pattern. Native busil starch was suitable to make amorphous and crispy food texture. It was also ideal for thickener or filler agents. Apart from being used as native starch, busil starch also potential to be modified and can be used more widely.
