"Tesis ini membahas mengenai bagaimana penggunaan perhitungan line balancing untuk menyusun suatu layout dengan melakukan pengaturan workstation pada masing-masing proses. Pada tesis ini dicoba dilakukan pendekatan untuk 2 jenis ketebalan kaca yang memegang porsi sales paling besar, yaitu 5 mm dan 12 mm.Output yang dihasilkan lewat tesis ini adalah keseimbangan proses kerja diantara semua workstation yang ada di PT. Maruni DayaSakti sehingga didapatkan penggabungan workstation yang paling efisien dan pada akhirnya bisa diperoleh suatu layout yang paling efisien.

This thesis discusses the use of line balancing calculations to prepare a layout through workstation setting in each process. In this thesis, approach to be tested for 2 types of glass thickness which holds the largest share of sales, that is 5 mm and 12 mm. Output generated through this thesis is a balance of work among all the workstations in PT. Maruni DayaSakti, so it can obtained the most efficient workstations merging and ultimately we can have the most efficient layout."

"The present work aims to improve the microstructure and hardness relatedproperties of age hardened Al6061-SiC reinforced composites produced by a two stage stir casting method. Three composites with2, 4, and 6wt. % (35-40μm) of SiC reinforcement are subjected tomicrostructural examination and hardness test at different locations to analysethe uniform distribution of the reinforcements in the matrix. As-castcomposites are solution-treated at 558°C, followed by an aging treatment conducted at 100, 150, and 200°C, during which peak hardness values are noted. The peak agedsamples are subjected to hardness and wear tests. In line with the objectives, ranges from 80-100% and 120-145% additional increase in hardnessvalues are observed over as-cast alloy during the aging treatment conducted at 100, 150 and 200°C, respectively. Lower temperature aging showssubstantial improvement in hardness and wear resistance over high temperatureaging in each respective group. Alsohigher weight percentages of reinforced composites show excellent wearresistance, due to the presence of eroded iron particles fromthe counter surface which is regarded as a beneficial effect during the wear test. The presence of SiC particles provides more sites for the nucleation of fineprecipitates. These fine precipitates hinder the movement of dislocation andthus increases hardness as well as wear resistance after the precipitation hardening treatment."
