The pandemic of Covid 19 has bring huge global impacts for almost all industries including oil and gas. Lockdowns from countries around the world is decreasing energy demand and create oversupply of oil and gas products. The oversupply condition has forced oil and gas companies to either slow down or even stop their production which has impacted both the production in both upstream and downstream operation. The objective of this paper is to share a prediction of new normal post Covid 19 for oil and gas industry in Indonesia. The price crash of oil and gas products during the global pandemic also push oil and gas companies to change their line of business from traditional hydrocarbon-based company into integrated energy company. The government from countries around the world including Indonesia is attentively focused on managing the COVID-19 pandemic and reducing its impact thus temporarily leave behind the subject of energy transition. Nonetheless, the climate and environment debate is unlikely to go away. Innovations that have lowered wind, solar and battery costs will continue and decarbonization will remain a necessity for the industry. The research methodology in this paper using literatur review and the sector that being analyze such as power generation, industry, transport and building sector. As result of study, it is predicted that energy transitions and decarbonization can even be accelerated by the current crisis

The oil and gas business is one of the industries that supports the Indonesian economy. The business chain involves many industries from upstream to downstream, including other derivative industries that are very diverse. The oil and gas business chain starts from the upstream side, the transportation/midstream industry, the downstream industry, to the derivative industries. The objective of this paper is to define the strategy how to accelerate oil and gas E&P business life cycle. In 2017, the entire Indonesian oil and gas industry, including the supporting industries, contributed 62.67% of Indonesia's GDP. So it is important for the government to manage the sector appropriately to take advantage of it as a driving force for the Indonesian economy and strategically take advantage of this momentum to prepare for Indonesia's future development growth. Before advance into strategic stimulation, it needs to be understood that there are several driving forces that can stimulate the growth of the oil and gas business in Indonesia. Some of these driving forces are the supply of fossil energy, market demand for fossil energy, upstream fossil energy prices, end-user fossil energy prices, global fossil energy prices, transport infrastructure and fossil energy processing availability, government regulations, availability of renewable energy, non-fossil energy prices, environmental regulations, technological developments, business competition in the energy supply sector, geopolitical, as well as Indonesia's economic growth in general

Pterois volitans, or commonly referred to lionfish, are fish species originating from Indo-Pacific waters but are becoming invasive in other regions such as the Caribbean and Atlantis. Various efforts have been made to reduce the number of lionfish, and one of them is by utilizing the venom on the spine. The venom extraction of P. volitans spines is done mechanically using sonication and centrifugation, and then protein isolation is carried out using salt. Coagulant activity from extract (crude venom) and lionfish venom protein isolate was done by counting PT (prothrombin time) and aPTT (activated partial thromboplastin time) which resulted that the crude venom and protein isolate of lionfish venom can accelerate blood clot (procoagulant) respectively up to 8.5 seconds and 6 seconds. Protein identification was made using LC-MS/MS device. The LC-MS/MS analysis showed that the protein isolate of lionfish venom contains Nomega-nitro-L-arginine methyl ester (L-NAME) compounds known to h...
