This research uses qualitative methods with data observation techniques, interviews and documentation. The results showed that the advertisement tax management was an effort to increase PAD in Palembang City, to someone who was trying to be managed properly. However, there are indeed several problems where the supervision and participation of the community with illegal billboards is still happening and the implementation of regional regulations is not running properly, therefore the PAD from the advertisement tax has not been maximized. The supporting factor in this research is the availability of Palembang mayor regulation number 18 of 2011 concerning requirements, and fixed procedures for collecting advertisement tax and then Palembang City Regional Regulation Number 8 of 2004 concerning Development and Retribution for Advertising. In addition, to support the vision, mission and strategic plans of the Tax Management Agency. Two things support the effectiveness of the advertisement tax contribution. Internal and external factors inhibiting factors. Obstacles in internal factors, for example, the application of sanctions for billboards arrears who have just appeared without the knowledge of the officers, and the lack of socialization from the Regional Tax Management Agency so that the public does not know about the existence of regional regulations regarding advertisement tax. Whereas in external factors, for example, the community's low awareness of paying taxes or they tend to avoid and are dishonest in the report on the results of the installation of billboards and taxpayers who live outside the city of Palembang.

Abstract

Ardiansyah. Evaluation of Regional Regulation Number 44 of 2002 concerning Peace and Order in Lima Belas Ilir Village, East Ilir I District. This study aims to: 1) Analyze and describe the Evaluation of Regional Regulation Number 44 of 2002 concerning Peace and Order in Lima Belas Ilir Village, East Ilir I District; 2) Analyze and describe the Supporting and Hindering Factors for the Evaluation of Regional Regulation No. 44 of 2002 concerning Peace and Order in Limabelas Ilir Village, East Ilir District I. The research design used in this study is qualitative descriptive. Descriptive research can be interpreted as a problem-solving procedure that is investigated by describing / describing the state of the subject/object of research (a person, institution, society and others) at the present time based on facts that appear or as they are (Nawawi in Klicit, 2008). The results of the study concluded that: 1) The implementation of Regional Regulation No. 44 of 2002 concerning Peace and Order in Limabelas Ilir Village, Ilir Timur I District has not been optimal so far. Problems related to peace and order still often occur, such as thuggery and violations by street vendors that disturb public order and order. Education has been carried out many times through socialization and approaches through local community leaders, but the number of violations has not been able to be suppressed and is still occurring. Related to this, the lack of a high level of public awareness in complying with the regulations is considered to be the main cause of frequent violations, plus the lack of optimal enforcement of violations committed, so that violators are not deterred and tend to be ordinary in committing violations; 2) Supporting Factors for the Evaluation of Regional Regulation No. 44 of 2002 concerning Peace and Order in Fifteen Ilir Village, East Ilir District I is the existence of clear rules or legal basis contained in Regional Regulation No. 44 of 2002 concerning Peace and Order itself, then the high commitment shown by the employees of the Fifteen Ilir Village Office. Meanwhile, the inhibiting factor is that there are still many residents of Lima Belas Ilir Village who do not understand Regional Regulation Number 44 of 2002, the level of public awareness in complying with regulations is still lacking, lack of supervision from related parties, so that in the implementation of Regional Regulation Number 44 of 2002 has not been able to be applied properly, and the approach taken to the community is still not optimal.
