Abstract

Calcium oxide (CaO) and calcium carbonate (CaCO3) are widely used in industry. CaO and CaCO3 can be synthesized or derived from limestone. The purpose of this study to determine the characteristics of CaO calcined limestone from Ambunten Sumenep. Lime in calcined at 850 ° C for 6 hours. Characterization of X-ray fluorescence (XRF) was conducted to determine the chemical composition of limestone, X-ray diffraction test (XRD) to find the lime crystalline phase and FTIR test to determine the absorption of wave number. XRF test results showed that the limestone chemical composition consisted of Ca of 95.37% as the dominant element, Mg of 4.1%, Fe 0.17% and Y by 0.39%. The XRD test results showed that the limestone crystal phase is ankerite (Ca [Fe, Mg] [CO3] 2) and after the calcined phase calcination is vaterite (Ca [OH] 2), calcite (CaO) and calcite (CaCO3). While the FTIR test results show that the CaO spectra are seen at 3741.24, 1417.12 and 874.14 cm-1.

Abstract

One of the strategic issues in the 2016-2030 SDGs (Sustainable Development Goals), the 7th (seven) goal is clean and affordable energy. The social engineering approach in the social, environmental dispute management of the affected community is an applied research from the case study of the Pasuruan FSRU development plan, namely building floating LNG storage and supporting facilities and facilities at sea, subsea pipeline construction located in the Madura Strait, in the north of the Regency Pasuruan and Sidoarjo Regency, as well as deploying land pipes in Permisan Village, Tambak Kalisogo, and Kupang, Jabon District-Sidoarjo Regency. This research is a descriptive analysis study, which is carried out with cross-sectional, in the study area. The data used in this study are primary and secondary. The primary data from participants in socialization activities of development plan were 33 respondents in Sidoarjo Regency and as many as 25 fishers respondents in Pasuruan City and Regency. Besides, the primary data from the questionnaire to 101 residents affected by land pipeline deployments and 29 people, fishing communities, joined in the HNSI in Pasuruan Regency and City. Often the development plans are hampered by the implementation, including strategic development plans, such as deploying fuel/oil and gas pipes, refineries, FSRUs, etc. due to the issue of dispute in the social environment. This study aims to support ongoing development activities, to underpin decision-making policies. The results of the study show that the community perception factor is very significant towards the development plan that must be managed. Management of these problems is a social engineering approach at the planning stage in the development process by involving various stakeholders ranging from the central government, local government, related agencies, NGOs, local figures and communities affected by the development
