Auto indoor hydroponics plant growth chamber

The objective of this project is to build an auto indoor hydroponics plant growing chamber that has an auto monitoring and controlling system. A ESP32 based hydroponics electrical system is built with the attachment of hardware components such as temperature and humidity sensor, light intensity sensor, water level sensor, and water flow rate sensor. The software development of the system is through Arduino IoT Cloud platform, which has an overall suitability in terms of features, cost, and user intuitiveness for starters. Results have shown that ESP32 can ensure stable power supply. After testing and validation, all of the electrical components are stored in a power enclosure box to prevent contact with liquid. In short, the developed auto indoor hydroponics plant growth chamber has effectively demonstrated the ability in easing the plant cultivation procedure for agricultural community

A design and fabrication of a solar agriculture water pumping system

This study explores the use of a solar driven water pump. PV technology replaces conventional electricity and diesel pumps by using solar energy to power DC or AC water pumps. The main objective of this study is to design and construct a solar-powered agriculture water pumping system and to evaluate its performance. The solar agriculture water pumping system used in this project consists of a 40-watt monocrystalline solar cell with an efficiency conversion of between 23% – 24%. This can supply power to a 16.8 W DC Flow Submersible Pump. It could lift the water up to 5m and a flow range of 700 Liter/Hour. The system also includes a PWM 30A Solar Charge Controller to regulate the input power to a 12V, 7.2A Sealed Rechargeable Battery. Finally, a 20m long watering kit with nozzles irrigation system is connected to a 12V DC Submersible Pump to water the plants

Aircraft Performance of Kenyalang Fuel Cell UAV

Kenyalang is a fuel cell powered Unmanned Aerial Vehicle (UAV) developed by Universiti Teknologi MARA (UiTM). This paper discusses the aircraft performances analysis of Kenyalang. Computational Fluid Dynamic (CFD) using Numeca software had been performed to obtain the aerodynamics characteristic of the Kenyalang UAV in the form of lift (CL) and drag (CD) coefficients. Unstructured mesh and standard one - equation turbulence model, and Spalart-Allmaras selected in the simulation. Lift coefficients (CL) and drag coefficients (CD) were studied at flight condition of Mach 0.08 (~26 m/s) at different angles of attack, α. The CFD data results were used to obtain Stall Speed, Take off Distance and Rate of Climb, and the results are shown in this paper

Discovery of Anthocyanin Biosynthetic Pathway in Cosmos caudatus Kunth. Using Omics Analysis

Cosmos caudatus Kunth. or “king’s salad” contains high values of nutritional compounds that act as health promoters. Although widely consumed for its medicinal value, information on phytochemical contents and their biosynthesis in the species is scarce. Among the interesting compounds are the anthocyanins that possess a dual role; an antioxidant and natural colorant. A complete anthocyanin biosynthetic pathway in C. caudatus was elucidated using transcriptomics, metabolomics, and anatomical approaches in this study. The transcriptomic analysis revealed genes encoding enzymes in the anthocyanin biosynthetic pathway and the genes encoding the transcription factors relevant to the latter pathway. A total of 11 anthocyanins of cyanidin, pelargonidin, and delphinidin derivatives that are significantly abundant in the species were identified, correlating with the anthocyanin mainstream gene pathway. The occurrence of anthocyanin was further validated by light microscopy. Anthocyanin pigments in C. caudatus were detected at the epidermal layer of the leaf, stem, and flower, and at the cortex of stem and root. To our knowledge, this is the first work that has delineated the complete anthocyanin biosynthetic pathway in Malaysia’s underutilized plant, C. caudatus Kunth. This study correlated multi-omics data that will help integrate systems biology and synthetic biology, for a detailed understanding of the molecular mechanism and characterization of the anthocyanin biosynthesis using heterologous expression studies
