Increasing the population in Kota Bangun Sub-District, Kutai Kartanegara Regency, in line with the consequence that growing needs for drinking water and raw water for local communities become a top priority. Public complaints about the increasing difficulty of obtaining clean water seem to be an obstacle that the Regional Government has yet to resolve fully. The production capacity of PDAM Kota Bangun is currently only 30 liters/sec, which is far from sufficient for the needs of all people in the Kota Bangun Sub-District. Economic feasibility calculation analysis utilized the NPV, IRR, and BCR methods and sensitivity analysis to obtain the economic feasibility for the value of developing intake and raw water networks. The results indicate, with a reasonable life condition of 30 years, the construction of water networks in Kota Bangun is still economically feasible. Reasonable with the minimum requirement of BCR = 1, with sensitivity analysis on two scenarios, considerations of 30% and 20% leakage, and 30.55% and 25% administrative costs. The results of the research show that IRR = 17.70%. If the analysis conditions are that investment costs increase by 10% with Fixed Benefits, the payback period is 6.8 years.

This research was conducted at the cake shop Strudel Malang to evaluate and select suppliers of apples based on green procurement using the AHP method. There are six criteria used, namely quality, technological capability, pollution control, environmental management, green products, and green competence. Each criterion has sub-criteria between 3 or 4 sub-criteria. The number of sub-criteria is used to determine the RI value. The RI value is used to calculate the CR value for each criterion. The results of data processing show that the highest CR value is in the technological capability criteria and the lowest CR value is in environmental management.
