Abstract

The concept of green campus directs the operation of universities as an environmentally-based educational institution which also has an important role for the environment of the future. In Semarang, there are 2 (two) state universities that are included in UI Green Metric program, namely Diponegoro University (UNDIP) and University of Semarang (UNNES). UNNES’ rank in 2014 UI Green Metric which is better than the UNDIP’s rank also indicates that students at UNNES have more perception about knowledge and high commitment to campus sustainability compared to students in UNDIP. There is a correlation between the knowledge and commitment of students to the vision of the campus in order to achieve campus sustainability, as well as there appears differences between knowledge and commitment to conduct pro-environment activities of both universities. To know the significance of difference perception about campus sustainability between students of UNDIP and UNNES, questionnaires to 165 student of UNDIP and 165 student of UNNES are disseminated. The result of the survey concludes that the perception of campus sustainability of UNDIP students is still under UNNES. To identify the root causes of the problem of low interest and knowledge of students to the campus sustainability in UNDIP, a tool of problem solving which is Root Cause Analysis (RCA) with Fault Tree Analysis technique is required.

Abstract

Company typically purchase products to meet annual needs with little regard for actual demand conditions, resulting in considerable overstock and high inventory costs. This research aims to control PT. Multi Indocitra, Tbk’s inventory by ABC analysis, demand forecasting method, and  (y, R) EOQ. A total of 60 products of the company are 6 products with A classification, namely Breast Pump Electric Pro, Multi Function Sterilizer, Portable Breast Pump, Breast Pump Manual, Silicone Nipple Eco 48 + 6 Pcs Mix, and Home Baby Food Maker. Performed calculations with 4 methods of forecasting, namely single exponential smoothing, double exponential smoothing, trend analysis, and ARIMA. Based on the smallest MAD, MSE, and MAPE values, we obtain s-curve trend model for Breast Pump Electric Pro, Breast Pump Manual, Silicone Nipple Eco 48 + 6 Pcs Mix, and Home Baby Food Maker and quadratic trend model for Multi Function Sterilizer and Breast Pump Portable. The total inventory cost becomes more efficient than the actual condition.The results of product forecasting indicate a trend that increases linearly in the next period. (y, R) EOQ can assist company in lowering inventory levels. The calculation results and graphs of (y, R) EOQ indicate a stable trend and company inventory can be more controlled, so as to minimize overstock and stockout because ROP value already take into account of safety stock value.
