This makes the effluent treatment challenging and adversely affects nearby aquatic environments if improperly treated. Phycoremediation uses microalgae in water and wastewater treatment. This research aim was to evaluate pollutant removal efficiencies, including chemical oxygen demand (COD), total suspended solids (TSS), nitrate (NO₃-N), turbidity, and phosphate (P), using microalgae Chlorella vulgaris (C. vulgaris) cultivation systems for livestock effluent treatment. The biomass weight of C. vulgaris in the cultivation systems was also observed. In this study, C. vulgaris was cultivated in closed cultivation systems in 5 L water bottles with different dilutions (100%, 75%, 50%, and 25%). The water effluent was compared to permissible values using the National Water Quality Standard (NWQS) class II for recreational water use. TSS was significantly removed by 61.97%, while COD and P were removed by 39.1% and 36.4%, respectively. The biomass growth was observed through the dry weight of the C.vulgaris. Therefore, the removal of nutrients from cattle farm effluent by phytoremediation using C. vulgaris demonstrates potential for treatment efficacy.","PeriodicalId":282600,"journal":{"name":"Advanced and Sustainable Technologies (ASET)","volume":"76 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140087384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is important to ensure that the irrigation in the greenhouse can provide ample water needed by trees. This study aims to assess the status of soil moisture and map its distribution in a greenhouse following the irrigation supply. Soil samples were collected at forty randomly chosen locations at two different intervals of before and after irrigation supply. The soil moisture content is determined by the gravimetric method in the laboratory. Two soil moisture distribution maps were developed using soil moisture data and the coordinates of the sample locations. Based on the maps, the soil moisture distribution of before irrigation was classified into two classes: low and moderate at about 50% coverage each, while 100% of the greenhouse area was within the high soil moisture class for after irrigation. The statistical results demonstrate that both soil moisture data before and after irrigation are different, with the mean soil moisture content increased by 8.73%, thus proving that irrigation systems installed in the greenhouse work effectively by providing ample water to the soil to achieve high soil moisture content in the greenhouse.","PeriodicalId":282600,"journal":{"name":"Advanced and Sustainable Technologies (ASET)","volume":"192 ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140275504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Levelling is one activity of land preparation that is done to achieve good crop establishment and high-yield production. There are several methods for achieving this. Implementing the major levelling method or the cut and fill method produces the best land levelling results, especially during the dry season. However, during the wet season, this method cannot be implemented to level the land as the amount of water in the soil would make it impossible to do any cut and fill operation. As a result, this study was carried out to evaluate the outcome of various methods of land levelling. Land levelling work was done using a power tiller, box leveler, and power harrow implements. Meanwhile, a Global Navigation Satellite System (GNSS) with the support of a Real Time Kinematic (RTK) system was used to map the levelness of the land. Land levelness mapping data was taken after each land preparation activity was done. Following that, the mapping data was processed to determine the levelling index for each activity. A high value of the levelling index indicated a more perfect levelling quality of the land. A total of two study plots at MARDI Parit Station, Perak, were used for this study, with each plot having an area of 0.5 hectares. The results showed that the average levelling index for the power tiller, box leveler, and power harrow was 60.0%, 76.8%, and 85.9%, respectively. The use of a box leveler resulted in the greatest increase in the levelling index, with a difference of 24.2% compared to an increase of 11.9% with a power harrow. In conclusion, some land preparation activities can improve land levelness quality even during the wet season. Furthermore, during the wet season, the use of a box leveler can be recommended during land preparation work to replace major levelling work that cannot be performed to improve the quality of the land's levelness.","PeriodicalId":282600,"journal":{"name":"Advanced and Sustainable Technologies (ASET)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139200368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Malaysia, Sarawak alone accounts for 70% (1.6 Mha) of the country's peatland. Tropical peatland is characterized by waterlogged conditions that promote the accumulation of organic matter (peat) from decaying plant material. These conditions strongly influence vegetation, species composition, peat type, and carbon release, making them crucial for climate change mitigation. The hydrology of tropical peatland is primarily influenced by the fluctuation of the water table (WT) depth in its catchment. This study analyzes five years (2011-2015) of field measurements on WT and precipitation (PT) dynamics, observing their trends. PT was found to significantly regulate monthly WT at the study site (p < 0.01), showing a positive correlation. However, PT exhibited a downward trend over the study period, although not significantly for all sites. Similarly, WT at MA, MC, and MD did not show significant trends, likely due to ENSO events from 2011 to 2015. In contrast, MB experienced a significant decrease in WT, possibly caused by a nearby river acting as a drain and accelerating WT lowering.","PeriodicalId":282600,"journal":{"name":"Advanced and Sustainable Technologies (ASET)","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139208407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the influence of key process parameters on the moisture content of energy pellets derived from Khaya senegalensis, a promising biomass feedstock in Malaysia. With a focus on unlocking the relationship between process variables and pellet moisture, a systematic experimental approach was adopted. The objective of this study is to investigate the effects of raw material moisture, feedstock particle size, compression pressure, and pelletization temperature on the manufactured biomass energy pellet's moisture content. By employing a comprehensive design of experiments and statistical analysis, the nuanced effects of these parameters are revealed on the moisture content of Khaya senegalensis energy pellets. The results illuminate the complex interplay between these process variables and the final moisture characteristics of the pellets. Understanding how these parameters impact moisture content is crucial for optimizing pellet quality, combustion efficiency, and storage stability. The study found a quadratic relationship between particle size, compression pressure, and pelletization temperature, indicating that larger particle sizes correlate with higher moisture content. Excessive pressure led to elevated levels while increasing temperature showed a decreasing trend. This research contributes valuable insights that advance the knowledge frontier of biomass pelletization, paving the way for enhanced utilization of Khaya senegalensis as a renewable energy resource.","PeriodicalId":282600,"journal":{"name":"Advanced and Sustainable Technologies (ASET)","volume":"64 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139201027","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

POME sludge obtained from the Jengka 8 FELDA Palm Oil was used in this study. The maize (Zea mays) was used as a test crop and planted in Rasau series soil (Entisols). The soil, leaves and stem samples were air-dried, homogenized and sieved. Heavy metal analysis identified the existence of Cu, Cr, Cd, Zn, Pb, Ni and Mn elements by the sequential extraction procedure using optical emission spectrometry (ICP-OES). The physicochemical of POME sludge showed that most heavy metals in each treatment fulfilled the WHO/FAO standard and were safe for human consumption. After applying treatments on Entisols, a small amount of Cu, Cr, Zn, Pb, Ni and Mn was retrieved from the exchanges phase. Small amount of Cr, Ni and Mn were identified in the stems and leaves. Zn, Cd, Pb and Cr were not detected in the bioavailable forms, while Cu was only available in the mixing ponds sludge samples.
