Published: March 2021

Abstract
The purpose of this study is to examine the gap analysis of environmental licensing both environmental permits, business licenses, and certification of oil palm plantations and their implementation in the field. This research is conducted in the eastern part of South Sumatra Province, focusing on six private companies in the field of oil palm plantations. Although the area has environmental management policies and regulations, many environmental problems still occur. This is indicated because there is a gap between the development of environmental policies related to licensing and their implementation in the field. The study is carried out using gap analysis method which is a common and simple technique in the evaluation of public policies. The results showed a gap value of less than 0.5 which indicates that the companies have implemented and complied in conducting business activities that refer to applicable environmental policies with the fulfilment of location permits and business licenses. It also signified that all companies have fulfilled the environmental permit component properly. However, there is a gap in terms of ownership of environmental certification. While almost all companies have already acquired ISPO (Indonesia Sustainable Palm Oil) certification, the government needs to provide assistance to companies to increase the company’s readiness to complete certification.

Published: March 2021

Abstract
Based on the recent implementation of the Ministry of Life and Environment (MOLE) Regulation No. P.15/MENLHK/SETJEN/KUM.1/4/2019 regarding Power Plant Flue Gas Emission, which supersedes MOLE Regulation No. 21 year 2008, there is a reduction of maximum Sulfur Dioxide (SO2) concentration in flue gas emission of Coal-Fired Power Plant (CFPP), from 750 mg/Nm3 @7% O2 content (dry basis), to 550 mg/Nm3 in existing CFPP, and 200 mg/Nm3 in CFPP constructed after the implementation of the regulation. Thus, arises the necessity for the consumption of Coal with lower Sulfur (S) content and/or retrofitting of Flue Gas Desulfurizer System (FGD) system in CFPP, not yet equipped with the FGD system. One of the applicable systems for retrofit is Sea Water FGD (SWFGD). This paper explores the energy and mass balance aspect of the SWFGD system for application in 300 MW subcritical reheated steam CFPP. Operational aspect is the increase of allowable sulfur content in consumed coal up to 1,162%, when the plant is retrofitted with SWFGD, and an increase in condenser cooling water of 0.6 °C due to SWFGD Absorber interface.

Authors: Lu’ayi A F , Lestari P 
Published: March 2021

Abstract
PP RI No. 41 1999 has been the only legitimate policy of national ambient air quality standard in Indonesia since more than 20 years ago. Most of standard for air quality parameters were set based on precautionary principle. It ratified other ambient air quality standards globally which is less representative from real conditions in Indonesia. Due to possibility of massive changes in national air quality conditions and various technological and non-technological factors driving them. The needs of national ambient air quality revision in Indonesia is raising. In addition, air quality as public value needs to be managed strategically by Indonesia’s government in order to provide basic need of society. More representative standard is a key for better monitoring and controlling ambient air quality in Indonesia. Hence, we proposed a critical mind map of integrated approach, air quality standardization principle, and brief process on how to reset national ambient air quality standard. It included the path role of public administrator, private administrator, and theorist in defining integrated framework of status quo and snap prediction. This mind map can be used as base of re-standardization ambient air quality in Indonesia. Furthermore, upcoming greater legitimate policy on this issue is gladly looked forward.
