ABSTRACT. Coal seam development is to a large extent controlled by depositional environment. Various depositional environments provide different rates of sedimentation which directly affects the nature and extend of coal deposits. A good understanding of the depositional environment of a coal bearing sequence can help predict the distribution and geometry of coal beds within a sequence. A sedimentological study conducted on a coal bearing sequence of the Tanjong Formation in Susui Block in the Pinangah area, Sabah has identified that the area was deposited in a mangrove and estuarine environment based on the presence of cross-beddings, fossils and coal seams with high sulphur content (ave. 0.98%).

processes that occur in groundwater due to the water-minerals reaction and water-coal reaction. Water samples will be collected from groundwater wells, dug wells, abandoned coal mine shaft as well as springs across the coal area. Water samples from tube wells in areas without coal layer will be collected as control samples. Laboratory analysis includes anions analysis using Alkalinity Titration, Turbidimetric and Ion Selective Electrode (ISE) techniques while major and minor cations will be analysed using ICP-OES. Minerals from rock samples will be identified using X-Ray Diffraction (XRD) while organic composition of the coal samples will be determined with Proximate and Ultimate Analysis. Measurement of the physical properties of water will be carried out in site using portable Multiparameter Quality Meter. The result of the physical and chemical analysis will be analysed and presented in various methods using Multivariate Statistical Applications (MSAs), Geochemical Modelling (PHREEQ) and Piper Diagram.

ABSTRAK. Secara keseluruhan negeri Sabah dibina oleh lima jujukan batuan utama iaitu batuan ofiolit yang mewakili kerak lautan, Formasi Crocker yang mewakili jujukan Paleogene, Formasi Sandakan yang mewakili jujukan Neogene, batuan volkanik Pleistocene seperti yang terdapat di daerah Tawau dan deposit alluvium seperti yang terdapat di Pulau Banggi. Prospek atau kajian potensi air bawah tanah dijalankan untuk mewakili kelima-lima jujukan ini adalah menggunakan peralatan dan kaedah geofizik. Kajian ini dijalankan menggunakan Abem Terrameter SAS 4000 yang menggunakan prinsip kerintangan elektrik untuk mengenalpasti sumber air bawah tanah berdasarkan nilai rintangan air di dalam jasad sesuatu batuan. Alat ini menggunakan arus elektrik secara terkawal yang dibekalkan oleh bateri 12 volt untuk melalui sesuatu bahan samada batuan atau tanah. Nilai rintangan arus elektrik yang melalui sesuatu bahan adalah dalam unit ohm/m yang tersendiri. Nilai rintangan ini boleh digunakan untuk meramal dan menentukan potensi air bawah tanah di kawasan kajian. Tafsiran data kuantitatif dalam bentuk keratan-pseudo dengan nilai rintangan tertentu akan memberi panduan terhadap kawasan kajian samada berpotensi untuk air bawah tanah supaya dapat dibangunkan pada masa hadapan. Dengan keputusan yang dicerap di kawasan-kawasan ini, nilai kerintangan untuk air bawah tanah boleh diperolehi dan dapat digunakan sebagai panduan untuk mencari lokasi akuifer di Sabah secara umum.

ABSTRACT. The work on synchronous monitoring of GLS hydrolysis products using CE has been reported, however, the reaction occurred in vial and not inside the capillary. Also, the method was tested on model GLS compounds and it was not applied on real samples such as plant materials. In this research proposal, in-capillary myrosinase-catalyzed hydrolysis of GLS will be developed to allow simultaneous monitoring of myrosinase activity and types of hydrolysis products. After initially developing the method using model GLS and myrosinase, the method will be validated on Moringa oleifera leaves. M. oleifera leaf is widely reported to possess anticancer properties due to its GLS contents. This work will be the first on the analysis of GLS in M. oleifera using CE.

GLUCOSINOLATE AND MYROSINASE ACTIVITY PROFILING UNDER DIFFERENT CONDITIONS IN PAPAYA (CARICA PAPAPA)

Annie Johanna bt Ahmad1& Loumi @ Noumi Surugau1 1

Industrial Chemistry Programe , School of Science and Technology Universiti Malaysia Sabah

Email: anniejohanna23@gmail.com

ABSTRACT. Carica papaya is a tree-like herbaceous plant, a member of the small family Caricaceae and widely cultivated for its edible fruits. Parts of the plant are used in diets as a fruit or vegetable; it is sometimes used as a therapeutic remedy for several of its medicinal properties. These health promoting effects are most likely due to the breakdown products of glucosinolates formed by the action myrosinase which catalyzes the hydrolysis of glucosinolate. Isothiocyanate, the most beneficial degradation product acting as insect repellents, bactericides, nematicides and putative anticarcinogenics in human. In order to find an optimal level of breakdown product and to increase their bioavailability, it is important to know the behavior of myrosinase and glucosinolate. Agricultural and food processing may affect the composition, content, activity and bioavailability of glucosinolate breakdown product, due to the cell rupture or glucosinolate and myrosinase degradation. The aim of this study is to investigate the effect of temperature, pH, Ascorbic acid, ferric and ferrous solution on myrosinase activity in papaya (seed,fruit and leaf). The study was conducted in Carica Papaya variety Eksotika. The enzyme myrosinase from papaya was treated with different conditions (temperature,pH,ascorbic acid, ferric and ferrous solution) with the addition of sinigrin. By using HPLC ,myrosinase activity was expressed as amount of transformed sinigrin in mmol min−1 g−1 DW.

REMOVAL OF ADSORBABLE ORGANIC HALIDES (AOX) FROM WATER TREATMENT PLANT EFFLUENT USING GRANULAR ACTIVATED CARBON (GAC)

(24)

ABSTRACT. Halogenated organic compounds have been increasingly produced from industrial factory nowadays. Some man made halogenated compounds are carcinogenic, toxic and mutagenic, and it may have harmful effects on human health and environmental. Adsorbable organic halides (AOX) also found in sewage, lake water and river water. Sewage will be treating in wastewater treatment plant and discharged into river and it may flow into water supply system. Since water treatment plant uses a large consumption of chlorine, therefore it is important to monitor AOX level and its removal in water treatment plant effluent.

EXPLORATION OF POTENTIAL MICROBIAL APPROACHES IN CONTROLLING GANODERMA

Louisiana Lulu1 & Chong Khim Phin1 1

ABSTRACT. Basal Stem Rot (BSR) is one of the most devastating diseases of oil palm (Elaeis guineensis Jacq.) in South East Asia, and Ganoderma boninense is the main causal agents for this disease. Economic losses will considered as significant when 10% of the stand has been infected and even worst, this fungus can kill more than 80% of stands by the time they are halfway through their economic life. Significant economic losses may be due to the zero yields from dead palm and reduction of weight and number of fruit bunches in living BSR diseased palms. Many control measures has been practiced including cultural, chemical, biological control and development of host resistance palms against G. boninense, however, until to date, there is no single method tested in vitro and on field has been proven to be effective against BSR. Therefore, the aims of this study are to evaluate potential microbes as biocontrol agent against G. boninense and to understand the interaction and mode of inhibition caused by the potential microbes against Ganoderma. To reach these objectives, several types of microbial combinations will be tested on seedlings and mature oil palm with different disease severity. Assessment on the potential of these microbes in suppression of Ganoderma colonisation will be measured using several indexes such as ergosterol content, MDSS (Modified Disease Severity Scale) and viability on GSM (Ganoderma Selective Media). Antagonistic activities of these microbes against G. boninense in – vitro will be evaluated using PIRG (Percentage of Inhibition Radial Growth) in Dual Culture Assay Test.

chemical, mechanical and biological measures have been reported in attempt to control this disease, but unfortunately, none has give satisfactory result. Therefore, a more reliable approach that could manage this disease, besides a continuous and sustainable oil palm production is worth to be further investigated. Introduction of microbes in disease management have been used for decades. An astute observation of low incidence of disease due to Ganoderma pathogen in natural ecosystem suggests that a healthy natural ecosystem can hinder the incidence of Ganoderma pathogen outbreak. In this respect, study on the potential of microbes in suppressing the growth of Ganoderma boninense and its effect to the soil microbial diversity were investigated. Three microbes-based products which are Living Soil Microbes (LSM), Agrinos (AGN) and Agriorganica (AO) were tested in this study. LSM contains multi-strain of Bacillus spp. and Trichoderma spp., whereas AGN consist of Bacillus spp., Pseudomonas spp. and Aspergillus sp. Meanwhile, AO comprises of 3 living food microbes which are Lactobacillus, Nattobacillus and Saccharomyces cerevisiae developed from Japanese fermentation and brewing technology. To examine the ability of the treatments in reducing BSR disease incidence, assessments in nursery and field trial were conducted. Ergosterol quantification was used to indicate the presence of Ganoderma infection. The results from both trials showed that LSM, AGN and AO were able to reduce the colonization of G. boninense based on the reduction of ergosterol content compared to untreated control. The effect of the application of microbial products to the soil microbial community was evaluated based on the isolation using Colony Forming Unit (CFU) and later identification using Biolog and molecular techniques. The numbers of CFU for bacteria and yeast after application of these microbes were remain unchanged, which were varied between 104_{to 10}6_{cfu/g and 10}2_{to 10}5_{cfu/g of soil} respectively. However, the number of CFU for fungi was increased up to 104_{cfu/g of soil.} Identification based on Biolog technique shows that new species arose and overcome the predominated species after application of these microbes. The new identified species are Enterobacter spp., Microbacterium spp., Burkholderia spp., Yarrowia spp., Paecilomyces spp., Neosertoya spp. etc. Polymerase Chain Reaction (PCR) and sequence homology was conducted for further identification of those microbes isolated from oil palm plantation soil down to strain level. In vitro antagonistic assay of microbial treatments on Potato Dextrose Agar (PDA) showed that only LSM has the activity against G. boninense (Percentage Inhibition of Radial Growth, PIRG=70%). Potential bioactive component produced by LSM during this interaction which inhibiting the growth of G. boninense was further investigated via Reverse Phase- High Performance Liquid Chromatography (RP-HPLC) and Liquid Chromatography Mass Spectrometry (LCMS).

ABSTRACT. This study was done to examine the seawater dependency of marine actinomycetes in the production of its bioactive secondary metabolites. A total of 100 marine actinomycetes strains were isolated from marine sponges collected within the conserved sea area of Sipadan Islands. All strains were subjected to NaCl tolerance assay to confirm that all strains are belong to marine origin. The fermentation process was done in mannitol-peptone broth with the presence and absence of seawater prior to the antimicrobial and DPPH assay. The data from DPPH assay showed that 22 strains have antioxidant properties (IC50 in the range of 56.3µg/ml to 99.1µg/ml) in the presence of seawater and 16 strains have antioxidant properties (IC50 in the range of 82.6µg/ml to 99.4µg/ml) in the absence of seawater. On the other hand, the presence of seawater has induced the production of antimicrobial compounds from 21 strains with inhibition zone ranging from 8mm to 19mm. In contrast, without seawater, only 12 strains were able to exhibit antimicrobial properties with inhibition zone ranging from 8mm to 11mm. The data from the assay showed that seawater indeed played an important role in the production of the antioxidant and antimicrobial compounds from marine actinomycetes.

NUMBER OF PARAMETERS COUNTING IN A MODEL

Yap Sue Jinq1, Zainodin Haji Jubok1 & Aini Janteng1 1

ABSTRACT. When a dependent variable is affected by a large number of independent variables and the analysis procedures are carried out manually, the number of parameters helps researchers to determine the number of independent variables to be considered in an analysis. However, when there are many parameters to be estimated in a model, the manual counting of them is found to be tedious and time consuming. Thus, this paper proposes a detail procedure to count them. To help understand this procedure, many illustrations are shown. The findings of this work enable researchers to count the number of parameters in a resulting model (selected model) with ease and speed. In addition, human errors caused by manual counting can also be minimised and avoided by applying the proposed procedure. These findings will also undoubtedly help many researchers save time when their analyses involve complex iterations. _____________________________________________________________________________ S2B-1

ABSTRACT. Small islands are often related to its vulnerability towards the limitation of freshwater resources. Therefore, groundwater resource is the sole option to meet water demand in most small islands. However, the rising of sea level consequently due to the climate change may have impact on the freshwater resources in small islands. Climate change effects are expected to substantially raise the average sea level. It is widely assumed that this raise will have impact on the saltwater intrusion in coastal aquifers which may reduce the amount of freshwater resources. The SEAWAT model is developed to investigate the saltwater intrusion length into the coastal aquifer under different climate scenarios.

ABSTRACT. Climate change is the significant change of weather pattern over long period of time and it is related to interaction of complex system. Climate change brings adverse impacts to Malaysia since the economics are relying on agriculture and natural sources. The aim of this section is to investigate and project the future climate for Malaysia by the end of 21st_century. The boundary conditions were obtained from global atmospheric model HadAM3H by using PRECIS-RCM as downscaling tool. The results indicate that the surface temperature increase across Malaysia region in both A2 and B2 scenarios during DJF and JJA. Relative to Baseline scenario, the average surface warming were between 2.8°C and 3.5°C under A2 scenario and between 1.9°C and 2.4°C under B2 scenario. The increase of surface temperature may associate with solar radiation from the sun. This study had shows that the total solar radiation was projected to increase in the future around 5 - 12w under A2 scenario and 3 - 10w under B2 scenario. For precipitation, the climate change trends were highly varied under both A2 and B2 scenarios. The seasonal means decreased during DJF and JJA in both climate scenarios. Relative to Baseline scenario, the averaged precipitation was projected to decrease between -23.5 % and -8.0% under A2 scenario and between -25.5% and -9.6% under B2 scenario. During DJF, high decrement of precipitation might be associated with the increased of dry spell length which probably related to reduction of cloudiness. These results suggest that significant change in climate variability could potentially increase the climate-related risks such as air quality impact and vulnerability in the region.

ABSTRACT. The oil palm mesocarp fibre, OPMF, is looked upon as a potential adsorbent to remove heavy metal from aqueous solution. In order to understand the adsorption performance of OPMF, a series of characterisation was carried out. From the scanning electron micrograph, mesoporous pores were found on the heterogeneous and irregular surface of OPMF. The BET surface area of OPMF was 3.63 m2_{/g, while the average pore diameter was 4.89 nm. Relatively} high content of carbon, hydrogen and nitrogen in OPMF contributed to the formation of functional groups like carboxyl and hydroxyl. These functional groups are responsible to bind to the heavy metal in adsorption process. It was found that OPMF has acidic nature at zero point charge as well as in aqueous slurry. There was insignificant amount of heavy metal found in the OPMF leaching test. The findings from the characterisation suggested that the properties of OPMF favour heavy metal adsorption.

School of Science and Technology, Universiti Malaysia Sabah

ABSTRACT. The application of geopolymer-technique in Malaysian ceramic industry is new. However, its appliance as a greener, environmental friendly option compared to Portland cement already gained a lot of interest. In this study, potassium based geopolymer ceramic from local kaolin clay and its crystal phase evolution based on sintering are presented. Local clays from Kimanis area in Sabah, Malaysia are characterized and optimized by flocculation. Samples were analyzed using XRD. XRD results shows that the reddish Kimanis clay mostly contain kaolinite and quartz, with hematite. The effects of weight percentage of Na3(PO4)6 deflocculant to the raw clay, calcination temperature of the Kimanis kaolin clay, concentrations of KOH and K2SiO3 activator on the microstructures of the geopolymer were investigated. The results indicated that the best deflocculant ratio was 1.0% and the optimum conversion of kaolinite minerals to amorphous metakaolin happened at 700oC. A 1:1 ratio of potassium based activator to metakaolin and curing temperature of 60oC for 24 hours was used to form the amorphous geopolymer paste. By firing the geopolymers at elevated temperature, a leucite-dominated glass ceramic were fabricated.
