Abstract

The library attendance at Petra Christian University is decreasing. We are interested in finding the factors affecting that attendance. In this study, we applied the LIBQUAL one of library quality measurements, and added some external and internal factors to answer the quest. Additionally, we also used the Confirmatory Factor Analysis (CFA) and Structural Equation Modelling (SEM) as tools for analyzing the constructs. As the result we found out that the factor that affecting library attendance is library as place, and the factor that doesn’t affect library attendace is teacher motivation.

The results of the Pareto diagram analysis shows that the priority defect are Over Painting (63%), Dirty Painting (60%), Uneven Paint (51%), Rough Paint (43%), Less Paint (29%), Power Take Over (53%), Porous Welding (45%), SpakBoard (39%), Less Welding (26%). The next step is to find the cause of the above defects with cause and effect diagram. It results that the cause are derived from human factors/worker, working methods, materials/raw materials and work environment.

Abstract

PT Surya Putra Barutama was not able to meet the market demand i.e. 500 units/month, since their production capacity was only 300 units/month. Therefore, to solve that problem we need to improve that capacity by calculating the standard time, production facility layouting, and calculating a new reward standard. At the end of this project, we found that, now the production capacity is 600 units/month.

Abstract

Musa acuminata paradisiaca is one of banana varieties, has a high demand in East Java thus highly potential to be developed. The highest production sites are located at Malang and Lumajang. Unfortunately, this type of banana are perishable that limited the selling period. An alternative way to solve is via improving the supply chain management. In this research, we developed some supply chain models and evaluate there performance using simulation with Vensim software. We used sales profit, lost sales, oversupply and availability to measure performance of the models, supply chain management at Malang and Lumajang. The results show that supply chain at Lumajang performed better than Malang interms of sales profit, lost sales and availability.
