Abstract- The project titled "Android Phone Controlled Prototype Model Of Solar Powered Sanitization Machine" presents a methodology for analyzing, fabricating, developing, controlling, and enhancing a Mechatronic Machine controlled by a Mobile Application. This machine finds applications in various public settings such as hospitals, schools, and colleges, particularly in rooms and corridors. Given the challenges posed by the Covid-19 pandemic, maintaining social distancing is imperative due to the virus's propensity for deeper penetration into the respiratory system, potentially causing inflammation and respiratory distress. The primary objective of this project is to develop a prototype model of a four-wheeled Mobile Application-controlled Mechatronic Machine, designed using Atmel Studios (Version 7.0). This Mechatronic Machine is operated via Arduino or NodeMCU ESP32 pins directly from Android smartphones, eliminating the need for manual code writing. The control system includes a Motor Control Shield and a dedicated mobile application interface. Additionally, the machine incorporates a solar panel for recharging its battery, enhancing its sustainability.

Abstract- Abstract— In worldwide distribution, chitin, which is present in crustacean shells, is the second most prevalent natural polymer. Chitosan is a natural amino-polysaccharide derived from chitin, with exceptional biocompatibility, biodegradability, and non-toxicity properties. Due to its characteristics and potential uses in sustainable agriculture, regenerative medicine, etc., chitosan has attracted much attention, resulting in an increasing number of publications and patents each year. This study’s objective is to synthesize and characterize nanochitosan from waste seafood, especially blue crab (Callinectes sapidus). The prepared nanochitosan by high energy ball-milling method using sea species waste was synthesized and characterized for morphology, pore size, porosity, functional group, crystallinity, and thermal analysis determination by SEM, BET, FTIR, XRD, and DSC. All the characterization data were related to commercial chitosan and confirmed the structure and properties of chitosan. The results provide better in their nano-size and are further associated with the degree of crystallinity in physicochemical properties compared to the commercial chitosan. The prepared nanochitosan is more beneficial for environmental applications like agriculture due to its biodegradability. In comparison to commercial chitosan, the application of nanochitosan in soil yields excellent results in terms of moisture content, water holding capacity, total nitrogen, and carbon, which are 39%, 84%, 3.1g/kg, and 47.7g/kg, respectively.

Abstract- The present research was conducted to understand the effect of basil leaf coating on the ripening duration and shelf life of banana cultivar Jahaji. The experiment was laid down under completely randomized design (CRD) with two treatments – T1 (uncoated) and T2 (coated with basil leaf extract) having seven replications. The coating was prepared by grinding the basil leaves followed by sieving and filtering to obtain a liquid extract of the leaves. The method of application was dipping the fruits in the liquid extract. Observations were made at periodic intervals to record the ripening duration and shelf life of the fruits. The ripening duration of T1 (uncoated) fruits was recorded as 8.5 days while that of T2 (coated) fruits was found to be 8.16 days. Again, the shelf life of T1 (uncoated) fruits recorded as 12.66 days while the shelf life of T2 (coated) fruits was 11.33 days. Thus, the results of the research was not satisfactory as the basil leaf coating application on banana cv. Jahaji could neither extend the ripening duration nor the shelf life of the fruits as compared to the untreated ones. Further research in this field is needed to come up with new such alternatives as a part of the solutions to problems reported in the present study.
Keywords— banana cv. Jahaji, basil leaf coating, ripening duration, shelf life, dipping method.

Abstract- The purpose of this study was to determine the mechanism of supply chain and the pattern of cassava of agroindustry supply chain flow and analyze the relationship between the components of SCM and the impact on supply chain activity improvement and agroindustry performance. Sample of research were producers of agroindustry local food of cassava as much of 106 respondents were taken by simple random sampling. The data analyzed by qualitative and quantitative analysis. Qualitative analysis used to describe the mechanism and pattern of cassava of agroindustry supply chain flow and principles of SCM. While quantitative analysis used to analyze the components, SCM activity improvement and agroindustry performance by using a structural equation model. The results showed that the mechanism of cassava agroindustry supply chain is the creation of collaboration and coordination among supply chain actors ranging from farmer, processor, distributor and consumer.
