This research involved comprehensive studies on thermal, physical, and morphological properties of SiO 2-Na 2 O-CaO-P 2 O 5 (SNCP) glass-ceramic at various sintering temperatures. The study in SNCP glass-ceramic using soda-lime-silica (SLS) wastes glass and clam shell (CS) wastes as the main raw of materials via conventional melt-quenching technique and solid state sintering are interesting and challenging by considering the research using waste materials to fabricate novel SNCP glass-ceramic. The main peaks, Na 3 PO 4 and Ca 3 Na 6 Si 6 O 18 were assigned to high crystallization temperature (Tc) at 650-950 °C. The density of samples increases at 550-750 °C and decreases at 850-950 °C due to the increase of sample thickness and higher specific volume at high sintering temperature. FESEM micrograph showed that existed porous increased at sintering temperature 850-950 °C contributes effect to low densification of the sample.

In rapidly developed countries such as malaysia, the importance of urban parks is recognized by development of new parks expecially in Putrajaya. This paper analyses the status of Putra Perdana Parks in Putrajaya in terms of vistors satisfaction towards park setting including people’s needs, accessibility, park safety, parks design and park facilities and mainteanace using Post Occupancy Evalution (POE) method. Data was compiled by meansof a literature review, observation and survey among visitors. Result shows Putra Perdana Parks is the effectiveness of a park’s design with visitors were satisfaction with score 4 out of 5 using 5 rating likert scale performance. Challenges releted to this publication should guide the landscape architects as well as the contractors to see the importance of conducting POE in the future and to upgrade the existing parks in Malaysia.
