Design of an Automated Hybrid System for Aquaculture and Agriculture Process and Its Performance Analysis

Fish farming (aquaculture) has become one of important food resources in human life. With the high demand of fish in the market, the fish farmer is forced to find the alternatives way to increase the fish farming production. The use of cement pond, land pond, canvas pond etc. will cause some obstacles to the fish. The ammonia is one of the waste produced from the fish manure and the feed waste. The increasing of ammonia inside the aquaculture system will lead to fish life interruption or death. Nevertheless, ammonia that is converted to nitrate has good potential for the growths of plants in agriculture system. This study aims to provide the solution of the stated problems by pumping the ammonia-contained water to the agriculture by applying an automation system. The water which is going through to the plants can isolate the ammonia and filter the good quality water back to the fish pond. To reduce the system cost, pH sensor is used as an alternative way to represent the ammonia level in the aquaculture system.  Besides, the system will be operated in a power-saving mode where the water pump will not be operated if the amount of ammonia does not exceed the limit. Hence, water pump will operate twice a day by scheduling it using a microcontroller in order to ensure the plant will receive the suitable amount of ammonia water for growing. Besides, the development of auto fish feeder is another added feature for this system

Design of a measurement device for air pollution concentrations using an open-source electronics software and hardware system

Contaminates air killed million people each year and incurs a cost of living on medical treatment. Normally, the authority manages the environmental control by practicing the air quality monitoring strategy by using high-end instrumentations which were very costly and requires periodical maintenance.

The average level of gas pollution, such as NO2 and ozone was recorded at 10.31 ppm and 17.31 ppm respectively. The developed device will help to monitor air quality in the residence and workplace environment. This system fills the gap between cost efficiency and reliability of other system architectures

A computational intelligence approach to solve the inverse problem of electrical DC resistivity sounding

Electrical methods have been widely used in geophysical surveying to obtain high-resolution information about subsurface conditions, since the last few decades. Resistivity is an important parameter in judging the ground properties, especially detecting buried objects of anomalous conductivity. Electrical DC (i.e. Direct Current) resistivity sounding is the commonly used technique to obtain the apparent 2-D resistivity of the region under investigation. Acquiring the true resistivity from collected data remains a complex task due to nonlinearity particularly due to contrasts distributed in the region. In this work, a radial basis function neural network (RBFNN) metamodelling approach is proposed to solve the 2-D resistivity inverse problem. The model was trained with synthetic data samples obtained for a homogeneous medium of 100O.m. The neural network was then tested on another set of synthetic data. The results show the ability of the proposed approach to estimate the true resistivity from the 2-D apparent resistivity sounding data with high correlation. The proposed technique, when executed, appears to be computationally-efficient, as it requires less processing time and produces less error than conventional metho

DEBIT AIR DAN SEDIMEN MELAYANG SUNGAI KODINA DI DESA WAYURA KECAMATAN PAMONA TENGGARA KABUPATEN POSO

The Kodina watershed with its river which empties into Lake Poso is one of the critical watersheds in the Poso watershed area. In addition to generating benefits that can be enjoyed by the community, changes in land use in the upstream watershed cannot be separated from the risk of land damage due to erosion, environmental pollution and flooding. The impact that is often seen is the increase in critical land, increased soil erosion and siltation (sedimentation) in the watershed area, and the occurrence of flooding in the rainy season and drought in the dry season. The purpose of this study was to determine the water discharge and the amount of floating sediment that was transported along the Kodina river. The purpose of this research is to provide information about water discharge and the amount of floating sediment production produced by the Kodina river which as a whole can help watershed managers in overcoming problems related to the hydrological aspects of the watershed area. This research was conducted for two months, from December 2015 to February 2016 at the Kodina Watershed, Poso Regency, Pamona Tenggara District. The method used in this research is a survey method, namely by taking direct measurements in the field, which includes: measuring water flow and taking water samples for analysis of floating sediment content. The results of the calculation of the data collected during the research period after being processed show that the water discharge flowing in the Kodina river cross section is 17.10 m3 / s and the amount of floating sediment transported with river water runoff is 36.53 gr / ltr. The relationship between water discharge and floating sediment discharge has a positive relationship with a correlation value of 0.895. This shows that the increase in the Kodina River Water Flow will be followed by an increase in floating sediment loads.Keywords: Water Discharge, Floating Sediment, Watershed

Electricity biogeneration using microbial fuel cells approach

Renewable energies are very important because they released clean gasses to the atmosphere. Hence, polluted air and water can be prevented by using renewable energy sources to generate power. Nowadays, primary fuel sources, especially fossil fuels, are used in generation of the electric energy. However, generation of electricity by using these fuel sources gives negative effects on the environment and human health. It is because the power plants will release substances for air pollution such as carbon monoxide (CO), nitrogen oxide (NOx) and also sulphur dioxide (SO2). Besides, Greenhouse gases (GHGs) was produced when the fossil fuels are burned. It will lead to climate changes and degrade the environment..

Energy harvesting from pressured water flow with IoT monitoring

Energy harvesting are required in order to improve the green technology. Energy harvesting or also known as power harvesting is the process where the energy is gain from the outside source for example solar energy, heat energy, wind energy and kinetic energy. This energy can be collected and converted to a useful electrical energy. Harvested energy give a small amount of power for a low energy electronics. This is because the energy converted comes from the recycle of waste energy, example, heat energy that produced from the operation of engine

An optimal proportional integral derivative tuning for a magnetic levitation system using metamodeling approach

A magnetic levitation system (MLS) is a complex nonlinear system that requires an electromagnetic force to levitate an object in the air. The electromagnetic field is extremely sensitive to noise which can cause the acceleration on the spherical object, leading it to move into the unbalanced region. This paper presents a comparative assessment of controllers for the magnetic levitation system using proportional integral derivative (PID) controller based optimal tuning. The analysis was started by deriving the mathematical model followed by the implementation of radial basis function neural network (RBFNN) based metamodel. The optimal tuning of the PID controller has offered better transient responses with the improvement of overshoot and the rise time as compared to the standard optimization methods. It is more robust and tolerant as compared to gradient descent method. The simulation output using the radial basis based metamodel approach showed an overshoot of 9.34% and rise time of 9.84 ms, which are better than the gradient descent (GD) and conventional PID methods. For the verification purpose, a Simscape model has been developed which mimic the real model. It was found that the model has produced about similar performance as what has been obtained from the Matlab simulation
