Extraction of Residual Oil from Palm Oil Mill Effluent (POME)

Palm oil mill effluent (POME) is oily wastewater produced during palm oil processing process. When organic compounds, such as residual oil in POME, are released into the environment, they deplete oxygen, causing harm to aquatic ecosystems. As a result, effective treatment methods for POME should be done before it is discharged into streams. In this study, residual oil is extracted before it can be safely released as effluent. POME residual oil was extracted using soxhlet extraction technique using two different solvents; methanol and n-hexane. For qualitative analysis of the extracted oil, Fourier Transform infrared (FT-IR) spectroscopy was used, and brine shrimp toxicity was tested on the POME to determine whether the POME has toxic effect on the organisms. The results show that 0.05g and 0.07g of oil were extracted from 500 mL of POME using the soxhlet method with methanol and n-hexane, respectively. Peaks at 3405 cm-1 indicate carboxylic acid O-H stretch, while peaks at 2923 cm-1 and 2852 cm-1 indicate C-H stretch. Other peaks at 1745 cm-1 and 1103 cm-1 correspond to C=O stretch and C-O stretch, respectively. The functional groups found are similar to those found in unsaturated fatty acids like linoleic acid in palm oil. Brine shrimp mortality test results show a 100% mortality rate when the shrimps were exposed to POME, indicating that POME alone is toxic to aquatic organisms.

IOT APPLICATION IN THE PRODUCTION OF WHITE PEPPER BERRIES

Iot application in pepper industry is still relatively new especially in the production of white pepper berries. The traditional process of producing white pepper berries has certain drawbacks especially in maintaining the quality of water during the soaking process. With the establishment of IoT application in the production of white pepper berries, it will improve the standards of production by monitoring the quality of water used and thus improve the final quality of white pepper

A new green index as an overall quantitative green performance indicator of a facility

In assessing the greenness of a facility, a few green performance indicators and assessment tools such as the Building Research Establishment Environmental Assessment Method (BREEAM), the Leadership in Energy and Environmental Design (LEED), and Green Building Index have been developed. Although these tools can help promote green building designs and operations, they do not provide a quantitative measure of the overall impact of a facility on the environment. This is due to the fact that most of the current green rating assessment tools utilise the point-based rating system. Such system has several limitations. First, it can only provide a relative measure of the greenness of a system. Secondly, the points awarded may not be consistent as it can vary from one assessor to another. Finally, the available rating tools do not provide a single indicator of the greenness of a system as each green element of a system is evaluated separately rather than as a whole. This paper presents a new tool for assessing the greenness of a facility that overcomes the aforementioned limitations. The use of the stock market composite index as a tool to assess the stock market performance has been extended to the domain of facility management that includes industrial and commercial buildings. The composite index has been utilised as the basis to develop a Green Index to assess and manage an organisation's level of greenness. The advantage of the composite index that could capture the movement of price within each stock and reflect it into a single composite index could be used in measuring and monitoring the impacts contributed by the individual green elements, on the environment. Results show that the formulation of the Green Index with weighting assignment using factor analysis would help organisations simultaneously optimise and improve their energy and water consumption, as well as waste generation. In addition, the Green Index graph provides facility managers with a graphical tool to visualise and gain insights on the performance trend of a facility

Evaluation of demand control ventilation impact on indoor air quality and energy efficiency of an office space

Ventilation is the process of introducing outside air into a building space. Ventilated air is usually heated, cooled, and dehumidified, depending on the weather conditions. The amount of fresh air delivered by the Air Handling Unit (AHU) is proportional to the maximum design occupancy of the building. Even though the space is only partially occupied, the actual occupancy rarely reaches the maximum design occupancy, but the AHU continually operates at the maximum ventilation rate. This frequently leads to excessive ventilation, resulting in higher than necessary energy consumption. This paper proposes to evaluate the impact of Demand Control Ventilation (DCV) on the Indoor Air Quality (IAQ) in an office space and the energy savings achieved through the utilization of DCV. DCV is a control system that regulates the rate of fresh outdoor air entering the Heating, Ventilation, and Air Conditioning (HVAC) system in response to the real demand for ventilation. The amount of ventilation rate is adjusted by DCV based on the number of occupants. This investigation involves two steps: simulation of an office space with a constant ventilation rate, followed by simulation of an office space by utilizing DCV to control the ventilation rate. The actual data of HVAC set point, estimated occupancy, air-conditioned floor area, and estimated electrical equipment load were used as the Carrier Hourly Analysis Program (HAP) input data to simulate the monthly data for electricity consumption and indoor air quality. Through the utilization of DCV, it was possible to maintain the IAQ, while simultaneously reduce the energy consumption by an average of 38.9 %. This approach is more practical and leads to more consistent IAQ; thus, can be used in numerous retrofit or conservation programs
