In his statement, Governor Koster emphasized that this policy is not intended to kill the businesses of local entrepreneurs, but rather to encourage the use of more environmentally friendly packaging. He gave an example of the use of glass bottles as a better alternative, as has been implemented by local producers in Karangasem Regency.
The Bali Provincial Government plans to hold a dialogue with all bottled drinking water business actors, including large companies such as Danone and local UKM actors, to socialize this policy. In addition to prohibiting production, this policy also applies to suppliers and distributors of single-use plastic bottled drinking water products.

On December 1, 2016, Koster stated his notes that the debate on the National Examination (UN) had been going on since 2004 and the DPR's position at that time was against the UN. The UN which at that time was still a graduation requirement was not in accordance with Law No. 20 of 2003 Article 51 so that negotiations took place between the DPR and the Government. The result was an agreement of 60% of the UN and 30% of the UAS. According to Wayan, the steps taken by the Minister of Education & Culture (Mendikbud) this time were more radical by eliminating the UN even though the steps were in accordance with the Law. Wayan suggested that when it was communicated to the media later, it would not be stated that the UN was eliminated but rather an evaluation policy that was carried out in stages. Wayan argued that the quality of education was not the same as the UN because psychologically the UN was used as prestige in several regions, thus opening up opportunities for leaks. Wayan added that the UN was something that was biased but received a fairly large budget. Personally, Wayan agrees with the elimination of the UN but it needs to be balanced with a policy of improving quality and not all are released to the regions because not all regions can commit.
On February 9, 2016, Koster was of the opinion that this institution must first be determined whether this institution is still operating or not. If so, will this institution be made into a type of Perum or Limited Liability Company (PT)?

"Institutional change with an efficiency approach alone cannot be based on theory on paper, but must be combined with previous government experience, so as not to be lulled by beautiful expressions that can actually lead you astray," said Koster at the DPR Building, Jakarta, Thursday (11/9/2014).
On March 17, 2015, Koster stated that he believed the 4th Indonesian Democratic Party of Struggle (PDI-P) congress would be quiet. The reason is, the majority of administrators, from the center to the regions, agreed to re-appoint Megawati Soekarnoputri as general chairperson again.

His decision received a protest from the head of Local House of Representative of the Province of Bali. After FIFA announced that Indonesia was removed as a host of the U-20 World Cup, Indonesian internet users expressed their frustration by flooding Koster's Instagram account comment column. In one of the interviews Koster said that The rejection was not his "attitude", he was only following the direction of the party's general chairman Megawati Soekarnoputri and adhering to Soekarno's principle that Israel may not compete officially in Indonesia's sovereign territory.
