Abstract

The existence of health facilities in the form of hospitals can improve the health standard of the people of Denpasar, as evidenced by the high life expectancy in 2022 equal to 75.3 years. By increasing the level of public health, other sectors will receive a positive influence, especially the economic sector. The high need for health facilities in the city of Denpasar has caused many investors to start pursuing the health business, especially hospitals. Businesses in the Health sector provide considerable profits with a relatively high Initial Rate of Return (IRR) or investment return rate of 50.44% (Arwati, 2016). In addition to providing benefits to the community and businesses, the health business, in the form of hospitals, also has a significant negative impact on the environment. The characteristics of the waste generated by hospital operations are in the form of domestic waste and B3 waste (hazardous toxic materials) such as leftover syringes, leftover laboratory washing water and leftover reagents. The management of the resulting liquid B3 waste can be carried out with the operation of an WWTP (wastewater treatment installation). It is necessary to carry out calculations related to the performance efficiency of the WWTP so as to ensure that the processed water is suitable for reuse and to calculate the clean water savings that can be achieved in order to apply the concept of a sustainable economy. Based on the research results, the level of treatment efficiency which is quite high, which is more than 90%, will produce processed water that can be reused to support operational activities. The use of ground water for operational activities can be reduced by 60% or around 48 m3/day.

Abstract

Taxpayers have the right to have their specific needs met when they participate in national development activities. Accordingly, this research aims to examine the factors influencing the compliance of Land and Building Taxpayers in Denpasar, with a particular focus on the roles of SPPT, Taxpayer Awareness, Service Quality, and Tax Sanctions, within the institutional context of the Denpasar City Regional Revenue Agency. The study covers the entire population of 192,297 active individual taxpayers in the region. To obtain respondents, purposive sampling was applied based on specific criteria, including (1) registered as an active individual taxpayer in Denpasar City, (2) having a history of paying land and building taxes, and (3) being willing to provide complete and accurate information. Using the Slovin formula with a 10% margin of error, a sample size of 100 respondents was determined, ensuring a representative and manageable cohort for detailed analysis. Multiple linear regression analysis was employed to examine the interrelationships among the variables. The results indicate that SPPT, Taxpayer Awareness, Service Quality, and Tax Sanctions all positively influence the compliance of Land and Building Taxpayers in Denpasar City. These findings emphasize the importance of these factors in enhancing taxpayer compliance.

Abstract

Adjustments to levy rates for land use carried out in Tahura Ngurah Rai Area are carried out to obtain tariffs that are in accordance with current conditions. The levy rate is determined by calculating the economic value generated by the Mangrove Forest in Tahura Ngurah Rai area. Assessment of nature using monetary units will show the economic value of the environment so that policy makers can make the right decision between preserving nature or advancing the economy. The purpose of this study was to identify the functions and benefits of Tahura Ngurah Rai mangrove forest and calculate the total economic value of Tahura Ngurah Rai mangrove forest. Tahura Ngurah Rai mangrove forest has three main functions, namely: biological, physical and economic functions. The economic value of the mangrove forest in Tahura Ngurah Rai area obtained using the total economic value method is IDR 72,020,018,026 per year or IDR 52,586,361 per hectare per year. The total economic value is obtained by adding up the direct use values, indirect use values, option value, existence value and inheritance value (bequest value).
