Correlation between hotspots and air quality in Pekanbaru-Riau, Indonesia in 2006-2007
Biomass burning is one of the main sources of air pollution in South East Asia, predominantly during the dry period between June and October each year. Sumatra and Kalimantan, Indonesia, have been identified as the regions connected to biomass burning due to their involvement in agricultural activities. In Sumatra, the Province of Riau has always been found to have had the highest number of hotspots during haze episodes. This study aims to determine the concentration of five major pollutants (PM10, SO2, NO2, CO and O3) in Riau, Indonesia, for 2006 and 2007. It will also correlate the level of air pollutants to the number of hotspots recorded, using the hotspot information system introduced by the Malaysian Centre for Remote Sensing (MACRES). Overall, the concentration of air pollutants recorded was found to increase with the number of hotspots. Nevertheless, only the concentration of PM10 during a haze episode is significantly different when compared to its concentration in non-haze conditions. In fact, in August 2006, when the highest number of hotspots was recorded the concentration of PM10 was found to increase by more than 20% from its normal concentration. The dispersion pattern, as simulated by the Hybrid Single Particle Lagrangian Integrated Trajectory Model (HYSPLIT), showed that the distribution of PM10 was greatly influenced by the wind direction. Furthermore, the particles had the capacity to reach the Peninsular Malaysia within 42 hours of emission from the point sources as a consequence of the South West monsoon
Struktur bahasa Balantak
Buku Struktur Bahasa Balantak ini merupakan salah satu hasil Proyek Penelitian Bahasa dan Sastra Indonesia dan Daerah Sulawesi Tengah tahun 1985 yang pelaksanaannya dipercayakan kepada tim peneliti dari Palu. Tujuan penelitian ini ialah untuk mengungkapkan data dan mengemu路 kakan deskripsi bahasa Balantak yang meliputi struktur fonologi, morfologi, dan sintaksisnya sebagai dokumentasi yang mungkin menjadi sumbangan pada
pengembangan ilmu bahasa. Dalam pelaksanaan dan penyelesaian tugas penelitian ini cukup banyak
hambatan yang dialami, antara lain , sulitnya komunikasi ke lokasi penelitian serta kurangnya buku路buku kepustakaan yang mendukung. Namun, dengan
bimbingan Tuhan Yang Mahabesar, penelitian ini dapat berjalan lancar dan dapat diselesaikan sesuai dengan target waktu yang telah ditentukan walau路pun hasilnya relatif belum sempurna
Reliability and validity of instrument on academic enhancement support for student-athlete using rasch measurement model
The purpose of this article is to develop and validate an instrument on Academic
Enhancement Support for Malaysian student-athletes. The instrument development process began
earlier in previous research's stages. Thirty-five questionnaires were distributed to Malaysia Public
University student-athletes who competed at the university and state levels. It took a week to collect
data, with a 100% return rate and one damaged questionnaire removed. Winstep version 3.69.1.11 was
used to conduct three analyses: item-person reliability and separation index, statistical fit, and
standardised residual correlation for item dependent. Cronbach's alpha of 0.96 indicates high reliability,
with all items displaying a positive value for item polarity. Thirty items were identified as being misfit,
five of which were removed and fifteen of which were revised. In the final analysis, ten pairs of items
were dictated to be redundant, and ten items were eliminated following selection. In total, 15 items were
removed from the instrument, leaving 82 items in the validated version. In conclusion, the instrument
developed is a valid instrument capable of validating the student-perception athlete's of the support
necessary for academic advancement during actual study
Komponen bahan inorganik dalam zarahan termendap semasa kejadian jerebu 1997
Kajian zarahan termendap dan komponennya telah dijalankan sebelum,semasa dan selepas fenomena jerebu yang melanda Malaysia pada tahun 1997 di dua kawasan perindustrian iaitu Kawasan Perindustrian Air Keruh, Melaka dan Kawasan Perindustrian Teluk Kalung, Kemaman, Terengganu. Antara parameter-parameter yang diukur dalam kajian ini adalah jumlah zarahan termendap, zarahan tidak larut, zarahan terlarut,abu,pH air hujan,anion (NO3-, SO42- ,Cl- ) kation ( NH4+ , Ca2+ , Mg 2+, K+ ) serta kandungan logam berat (Pb, Cd, Fe, Zn, Mn, dan Cr) dalam air hujan. Hasil kajian menunjukkan bahawa jumlah zarahan termendap meningkat dengan ketara (p< 0.05) semasa jerebu berlaku berbanding keadaan biasa. Antara komponen lain yang menunjukkan peningkatan yang ketara adalah NO3-, SO42, NH4+ dan Ca2
Colourimetric determination of features of an air sampling technique optimal for detection of surfactants
Surfactants in the atmosphere may act as cloud condensation nuclei, with a potentially negative impact on the global climate. Therefore, accurate determination of surfactants is crucial in order to investigate the possible effects of surfactants on the atmosphere. The aim of this study was to identify the optimum sampling method for measuring the maximum quantity of surfactants present in ambient air. Air samples were collected using a range of air sampling pumps that were made to vary in terms of flow rate, storage period, type of absorbing solution and the characteristics of the impinger tube. Samples obtained were analysed by colourimetry for anionic and cationic surfactants as methylene blue-active substances (MBAS) and disulphine blue-active substances (DBAS), respectively. Absorbance was measured at 650 nm for MBAS and 628 nm for DBAS using UV-visible spectrophotometer. We found that the optimum sampling method consisted of an absorbent solution (deionised water, buffer solution and methylene blue/disulphine blue solution) with the flow rate of 1.0 L/min. The concentration of surfactants in all sampling methods remained constant regardless of the storage period (1 day and 4 days), indicating that surfactants in the absorbing solution are quite stable. Covering the impinger tube was shown to influence the amount of both anionic and cationic surfactants detected
