Permeability Characteristics of Tropical soils at UTP Campus

Soil permeability varies spatially and this spatial variability causes difficulty to representing a soil with a deterministic or precisely defined set of permeability value. In Malaysia, the studies on the spatial variability of soil permeability are limited. This study examines the spatial variability of soil permeability in UTP campus area located in Tronoh. The objective is to map the variation in soil hydraulic characteristics in the study area. Statistical and geostatistical method was used in this study. 50 soils sample were collected on the field from predefined geo-grid location. GPS (Global Positioning System) is used to determine the reference points for the making of the the geo-grid sampling locations. Samples were then taken to the laboratory for analysis. The method that used to measure the permeability of the soil samples was The Falling Head Permeability test. Laboratory test result were then subjected to statistical and geostatistical analysis. Digitizing Software was used to digitize the map of the study area. Geostatistical characterization was performed by the GS+ and Surfer Software. Kriging method is used for the interpolation of the ensample location and preparing map of the spatial variability of the permeability rates in UTP campus area is prepared. Besides, it also can allows mapping of the spatial distribution and the normal statistics will helped in identifying causes of the variability in the soil permeability. Others, even the semivariogram shows the consistent result, however the relatively low r2 (0.638) show poor fit to data. This is because in the fact that the number of the sample is not enough for that extend of area studied. The significant variation of soil permeability exists in the area of studied are shown in the result. Larger range and the lower sill indicates that the soil permeability are spatially dependent over long distance (large range) and the variability is low (indicates by low sill). Land disturbance and land topographic conditions donate to the variability of soil permeability

Synthesis and characterization of adsorbent derived from pandan leaves for methylene blue removal

Dyes are an important type of pollutants that come in a large amounts which originated from industries such as textile, paper and pulp making, and petroleum. The elimination of dyes from wastewater is challenging as they have a synthetic origin and possess complex aromatic molecular structures which caused them to structurally inert and difficult to biodegrade, and unfortunately, the industries have overlooked this aspect in the treatment of wastes. Adsorption is known to be the superior technique compared to all other chemical for dye treatment. In this study, adsorbent was synthesized through chemical activation process by NaOH. The pandan leaves adsorbent was characterized by Fourier Transform Infrared (FTIR) and Brunauer-Emmett-Teller (BET). Results revealed that the pandan leaves adsorbent was successfully synthesized. The BET surface area for the adsorbent is 6.79 m^2/g. The adsorption capacity was found to be dependent on reaction time, pH, adsorbent dosage and initial dye concentration. The highest amount of adsorption capacity is 24.113 mg/g that was found at the adsorbent dosage of 0.02 g. The adsorption data for MB dye were well fitted Langmuir isotherm model and obeyed the pseudo-second order kinetics model. The value of standard Gibbs free energy for temperature 303.15 K is -1.895, temperature 323.15 K is -5.228 and temperature 333.15 K is -5.581. The negative value of standard Gibbs free energy indicated the feasibility and spontaneity of the adsorption processes and the positive value of enthalpy change confirmed the endothermic nature of overall process

Fenomena penyalahgunaan dadah dan hidu gam serta kesannya kepada sistem nilai

Gejala sosial yang semakin menular di dalam masyarakat perlu diberi perhatian yang serius. Jika dahulunya ia berlaku di kalangan belia dan orang dewasa namun kini golongan remaja dan pelajar sekolah sudah terlibat dengan gejala sosial yang kini berada di tahap yang membimbangkan. Kertas kerja ini cuba membincangkan beberapa aspek dari gejala sosial serta langkah-langkah bagi menanganinya. Perbincangan akan ditumpukan kepada gejala penyalahgunaan dadah serta fenomena hidu gam berdasarkan hasil penyelidikan yang dibuat baru baru ini di kalangan pelajar sekolah di negeri Sarawak. Gejala hidu gam, walaupun tidak diberikan perhatian serius, sebenarnya merupakan ancaman yang sangat merbahaya. Sekali imbas gejala ini mungkin tidaklah merbahaya sebagaimana dadah, tetapi sebenarnya, dalam beberapa aspek bahayanya lebih serius dari penyalahgunaan dadah. Suatu realiti yang tidak dapat dinafikan kebanyakan gejala sosial yang berlaku melibatkan bangsa Melayu yang beragama Islam. Kertas ini akan membantu seminar untuk mendedahkan aspek-aspek yang perlu ditangani oleh semua pihak
