As an educational institution, there is a need to be well informed especially about pressing issues and concerns affecting humanity and one such issue is on the genetically modified organism. GMOs are organisms that have gone through some genetic alterations. It has become a business that may have started with good intentions, but that which have been described by experts as something that can also affect large numbers of people in yet unforeseen ways, that some are not even aware of the fact that they are consuming GMO food. The study aimed to find out the level of awareness of Technology and Livelihood Education students in a State University in Region 02 on Genetically Modified Organisms with the hope that many people will acquire knowledge for the development of the community. It made use of the quantitative descriptive-inferential approach using a questionnaire checklist validated by experts. Weighted mean and Analysis of Variance were used to analyze the data gathered. Findings show that most of the respondents have a low level of awareness on genetically modified organisms in food products and have a very low level of awareness in terms of genetically modified plants, animals, medicine, and the possible health risks these can bring about. Furthermore, findings reveal that there is a significant difference on their level of awareness in terms of genetically modified food products, plants, animals, medicines. With the findings and conclusions gathered, there is a great need to raise the level of awareness of the respondents on genetically modified organisms. Thereby, the researchers proposed the University Awareness Program on genetically modified organisms making every student in the university fully aware of the issue of GMOs.

Peanut processed products sold in the local market are still limited but the potential is great. There is a need therefore to explore more diversified peanut products that are acceptable, nutritious, and within the buying capacity of the general consumers. This study aimed to produce crisp; a very popular snack food utilizing rice and peanut at various levels applying some appropriate technologies. The products were analyzed and evaluated to determine their sensory qualities, nutritive value, and profitability. The treatments of the study were different proportions of rice and peanut. Replication was done three times and Completely Randomized Design (CRD) was used. The crisp products were rated and results showed that these had good sensory qualities. Peanut significantly improved the taste and crispiness acceptability as well as the protein quality. Based on cost and return analysis, the commercial processing of the products either in a household or small scale operation indicates good economic profitability.

The increasing developments in Renewable Energy Sources (RESs) which provide benefits to address the growing future electricity demand need to be studied in depth. For better power performance to solve difficulties in power production, the On-grid system integrated with RESs can be adopted. This paper is aimed to shed light on two main RESs which are Photovoltaic (PV) and Wind Turbine (WT) with battery connected to the utility grid as an on-grid system to achieve the Sustainable Development Goal 7 (SDG7). In this paper, the Energy Management Strategy (EMS) is applied to achieve the objective functions which are Levelise Cost Energy (LCE), and Loss of Load Hours (LOLH), and to calculate the Greenhouse Gas (GHG) emission. Hence, Rule-Based EMS (RB-EMS) is supported to strategies the mechanism of the system by implementing a recent nature–inspired method namely Ant Lion Optimization (ALO). This paper encourages researchers to adopt the aforementioned method for solving problems due to the available benefits. The primary contribution of this article is to provide up-to-date and state-of-the-art knowledge to achieve the proposed objective functions of this study by utilizing MATLAB environment.

Fires and explosions are not the most common cause of injury to construction sites; such accidents can have devastating effects on workers' health. Out of 302 cases reported to the Department of Safety and Health (DOSH) from 2010 to 2019, about 0.33% of Malaysia cases are fire and explosion. It is discovered that the cause of death is inadequate supervision and lack of safety training, and the trade worker affected is construction labour. This paper developed an AHP model for fire and explosion accidents' significant factors and determined their relative weights and priorities. Worker's unsafe actions have a maximum weight of 80.98% for the significant factors based on the proposed AHP model, followed by unsafe site conditions with 10.89% and management factors with 8.13%. Financial constraint carries the most weight with 20.22% for management factors, unsafe working and operating procedure, presence of combustibles on-site, presence of an electrical hazard, improper on-site storage for flammables, and improper on-site storage of explosives for blasting with 14.28% each carry the most weight for unsafe site conditions. Rushing to complete the job and use of faulty or unsafe electrical equipment or machinery carry the most weight, with 17.24 % each for workers’ unsafe actions.

In this study, mechanical properties of commercially manufactured hybrid particleboard from mix-tropical wood and rubberwood with four different densities at 25mm thickness have been investigated. The particleboard sample cutting and testing was in accordance to EN312:2013. The density of particleboard is identified with interval of 10kg/m3 for different densities which include 660kg/m3, 670kg/m3, 680kg/m3 and 690kg/m3. Particleboards were made with the ratio of 40:60 for mix-tropical wood particle and rubberwood particle respectively. The particleboards were prepared with urea formaldehyde (UF) with E1 formulation with addition of wax and hardener. Increment of 10kg/m3 density for each particleboard led to increase in internal bonding (IB), bending testing include modulus of rupture (MOR) and modulus of elasticity (MOE), surface soundness (SS) and screw edge (SE) withdrawal. It was found that with board increment of 10kg/m3, the improvement was not statically significant except that for MOR. All panels met the minimum requirements of standard.

This work performs a quantitative assessment of the impact of rooftop PV installation on building’s net energy demand using model of roof structure and steady state thermal simulations. For this purpose, roof structure typically used in Faisalabad, Pakistan is modeled with and without the shading effect due to a 395 W commercial rooftop PV setup. The simulated parameters include the impact of PV module’s dimensions, mounting position/angle alongside roof size and ambient conditions on heat load of air-conditioning system to maintain a temperature of 25 °C within building’s top floor. During the daylight hours of July, the heat load added by the roof on average reduces from 150.87 BTU/h/m2 without PV to 118.16 BTU/h/m2 with PV structure. This 20.05% reduction in energy demand has been achieved with July’s maximum daytime solar and infrared irradiances of 792.2 W/m2 and 466 W/m2 recorded at an average ambient temperature of 35.5 °C and wind speed of 2.75 m/s. This study provides valuable data on optimization of roof layer structure during building’s construction in anticipation of PV system installation at a later stage. Also developed techniques/methods to reduce building’s energy budget due to PV installation, can be valuable input for construction industry as well.

Urbanization, agriculture, industrial work and greenhouse effect are the leading causes of the climatic changes all over the world. The impacts of climatic change include losses of biodiversity, rise of sea level, shifts in weather pattern, changes in fresh water supply and an increase in harsh / extreme weather conditions such as floods and droughts as well as glaciers melting and various health impacts on living organisms. It is a key concern that has been impacting human health, plants as well as animals. The concept of green revolution is based on plantation activities, increasing aforestation, decreasing deforestation, overgrazing etc. and such processes enable to protect and benefit the economy, habitat, people and planet. Plants use CO2 and other toxic materials which can persist in the environment. The findings of this study showed that plantation activities should be considered on large scale for monitoring of environmental quality. As plants act as natural lungs of Universe and release oxygen providing good quality of air. In order to mitigate problems regarding climatic changes, we need to minimize the different types of environmental pollutants and to maximize the plantation activities to overcome the climatic changes all over the world.
