Latar Belakang Pusat Falak Sheikh Tahir
Perletakan batu asas bangunan Pusat Ilmu Falak telah dilancarkan pada bulan Jun 1988 ( Syawal 1408 ) dan sekaligus merupakan sumbangan permulaan yang amat penting kepada cerapan dan eksperimen kegiatan ilmu falak di Malaysia dan di rantau ini. Pusat Falak Syeikh Tahir dibuka dengan rasminya pada hari Rabu, 30 Rabiul Awal 1412H bersamaan 9 Oktober 1991, bertujuan untuk memenuhi keperluan saintifik dalam bidang kritikal seperti kalendar Islam, kajian senja, pemupusan dan pembiasan atmosfera, kenampakan anak bulan serta perkara-perkara yang berkaitan dengannya
The Study of Flocculant Characteristics for Landfill Leachate Treatment Using Starch Based Flocculant from Durio Zibethinus Seed
Background: Flocculation has been extensively used as a semi-aerobic landfill leachate treatment, prior to other treatment methods. Although inorganic and synthetic polymers are prominent in landfill leachate treatment, its application may introduce potentially toxic residual. As alternative to potential risk, starch based flocculant had been produced from durian seed waste. Plus, no attempt has been made to avail abundant waste of Durian Seed Starch (DSS) as a natural flocculant for wastewater and leachate treatment. In this paper, an attempt has been made to study the characterization performance of DSS in the flocculation process. Jar test results had ascertained that optimum pH and dosages values for DSS flocculant were pH 6 and 4000mg/L with removal of true colour and turbidity were 34% and 36.9% respectively. The scanning electron microscopy (SEM) images show the presence of contaminated particle layer on top of the DSS after the treatment process. The Fourier transform infrared spectroscopy (FTIR) analysis showed DSS was the major constituent of the floc. FTIR results verified that the agglomeration consist of leachate contaminants. Therefore, DSS could be a feasible selective flocculant in reducing the usage of inorganic polymer for semiaerobic landfill leachate treatment

Paper Fiber reinforced foam concrete wall panelling System, 2nd International Conference on Built Environ ment in Developnig Countries (ICBEDC 2008). Author Profile Drs Hidjan MSc. Eng received the Drs of Physics from Gadjah Mada University in 1986 and MS
ABSTRACT One type of a new product for the usefulness of panel wall material containing mixed composite of cement, sand, and recycle paper called as Paper Fiber Reinforced Foam Concrete (PFRFC) as upon of the reinforcement addition is expected can improve materials quality for non load bearing wall. Pursuant to study of paper fiber in mixture of concrete it was produce a strong structure materials, environmental friendly and economical. By that this study have practiced using paper fiber with other mixture of lightweight foamed concrete to search out the good material for lightweight concrete in term of the tension strength, compression strength and absorption of noise. Paper fiber is come from wood fiber which have experienced of crushing process, condensation, and pickling have idiosyncrasy in absorbent strength of sound and strength of tension but it is sensitive to water, slow harden and increase the density of foam concrete specimens. Experimental work of PFRFC have been conducted in the form of prism specimen, panel wall and cube, with water ratio, cement, and sand is 0.45 : 1 : 1.5 and mixed with 5%, 10%, 15% and 20% of paper fiber. The research have shows that, with addition of paper fiber the flexural strength of the Paper Fiber Reinforced Foam Concrete (PFRFC) is increases although the compression strength of PFRFC is not as good as the flexural strength. The strength of wall panel of PFRFC is better compared to Normal Foam Concrete (NFC) wall panel in terms of the flexural strength and noise absorption. The density discovered is less than normal concrete density, which are 2400 kg/m 3 . The PFRFC density is appropriate for the lightweight material for wall panel, which is the range of density, are 800 -900 kg/m 3 for the specimen of PFRFC cube
