Indonesia has the capability to produced local products such as vehicle radiators. Many studied were carried out to characterize the radiator material. But it still needs to compare local products and imported products. This study carried mechanical properties and microstructure analysis for Marcedes Benz's core radiator and local radiator. The tools used in this study are microhardness tools, optical microscopes, and XRF. The result shows that the Mercedes-Benz radiator binding material before the heat treatment process, using an optical microscope shows the invisible results of a collection of atoms and the matrix and grain boundaries. On local radiator material, Not yet seen the collection of atoms and matrix and grain boundaries. White grains of Mercedes Benz radiator material is more abundant than local radiator materials. Chemical composition test results are; local radiator material content is dominated by three elements Ca (26.3%), Zn (44.4%) and Cu (13.9%) Cu (2.48%), Fe (45.15%), and Mn (44.88%). The German Mercedes-Benz element contents are; Fe (28.7), Mn (27.5), Ca (39.2). The hardness of the Mercedes-Benz radiator before heating is 43.4 HV, after being heated 39.2 HV. The hardness local radiator material before heating 43.5 HV and after heating 38.2 HV.

Industrialization on renewable energy is needed to begin to avoid dependence on fossil fuels. West Nusa Tenggara (NTB) Province has the potential for the development of bioethanol which is integrated with the Small Modular Reactor (SMR) nuclear reactor. Through this study, the economics of sugar- ethanol plant and SMR reactors was calculated, as well as development schemes supported by policy recommendations will be presented. This study uses cash flow modelling from a sugar-ethanol plant and SMR to determine the economics of the project. The potential site is mapped by using scoring method to obtain the best location. The SMR reactor can operate with Internal Rate of Return (IRR) of 9%, Net Present Value (NPV) USD 2,325,347,181, and payback period 13 years. The sugar-ethanol plant has IRR of 12.6%, NPV 441,278,716, and payback period of 10 years. The appropriate locations for the construction of the SMR reactor are in Bima and Dompu districts, based on mapping analysis both locations have potential for future development.
