Turbulent flow in the open channel, often exhibit a phenomenon bursting in expansion or inhibition case. This phenomenon disturbing to the flow at the turbine area. In this study, Research to analyze the occurrence of interference bursting in the river turbine area, done by simulating the river flow with a variety of depths ratio y/L, using vertical turbine NACA 0018 in a trapezoidal channel, with k-ԑ turbulence models in CFD. From the simulation results the smaller ratio of the depth y/L, the force of turbulence flow (bursting flow) at the turbine increases.

An ANP (Analytic Network Process)-based Multi-Criteria Decision Approach for The Selection of Sugar-Cane Industry Development Ferizandi Qauzar Gani; Ridho Hantoro

Acknowledging the issue of energy sustainability, the sugar industry has begun to look at plans to sell electricity to address energy sustainability issues. A scenario with the potential to sell excess electricity motivates this research to analyze the strategies of the sugar industry development. In such situations an ANP approach is applied for the selection of appropriate strategies. This study analyzes the potential for electricity sales in two alternative plant development strategies of three sugarcane industries which from the results, Strategy A (cogeneration scheme) allows to sell electricity for 223-293 days while strategy B (independent power plant scheme) allows to sell throughout the year. The result also shows that by using ANP, it is found that strategy A is better than strategy B

Emission Reduction Study for Eco-Campus Program, Case Study in Sepuluh Nopember Institute of Technology Indonesia Ridho Hantoro; Detak Yan Pratama; Endah Laksmi Nugraha; Rizky Nanda Puspitasari

Emission of CO2 in Indonesia is high relatively and have reached 1,55-ton carbon (5,67 ton CO2 – eq) per capita. It is predicted to increase up to 3,22-ton carbon per capita in 2050 as increasing of population growth. Indonesian Government has issued the policy for decreasing greenhouse gasses effect below 26% in 2020. It proposed to all of society not only public and private institutions, but also education institution like campus. This study is aimed to identify the factors which can influence greenhouse gasses effect, including carbon emission in transportation, waste management and electrical consumption in Sepuluh Nopember Institute of Technology (ITS). It is projected to support implementation of ITS eco campus program more effectively. Therefore, this study has formulated local planning and policy which can be implemented by campus community to decrease carbon emission and organize ITS as real eco-campus.
