Monitoring the quality of the river is essentially to know the status of the periodic quality of the river. Good assessment of river water quality should use a combination of physical, chemical and biological parameters. One way that can be done to describe water quality in an area is the primary productivity in the water. Primary productivity is the amount of organic material produced by autotrophic organisms with the help of sunlight. Perifiton as a river microorganism, will provide dissolved oxygen (DO) through photosynthesis to maintain most of the life of the surrounding water, then Periphyton can respond quickly to environmental changes, this is an indicator of changing conditions (Gaiser 2008 and Lakewatch, 2000) in Brown and Wright (2016) Chemical reactions that occur in the aquatic environment also involve interactions between ions and other phases. Some important interactions in the waters are the occurrence of photosynthesis by algae and the exchange of dissolved solids with dissolved gases in water. The same exchange occurs when bacteria degrade organic matter (often in the form of particles) in water. Some important elements move around in aquatic systems as colloidal chemical compounds or are absorbed into soil particles. The equilibrium of physical chemical reactions in waters involves sediment, gas, and water. Sediment is a layer of material or material that covers the bottom of small rivers, lakes, reservoirs, bays, and oceans. Sediments contain fine mixtures and subtle minerals, including clay, silt, and sand, which mix with organic materials. These materials may experience changes in composition from pure mineral ingredients to main organic ingredients. Sediments contain biological ingredients, chemicals, and pollutants in water.

The problems which arise in every rainy season in Singaraja are flood and the back up of water. They are caused by the inability of totally functioning drainage system. The lack of awareness and participation of the society in maintaining the drainage system nearby causes clogging in the drainage system caused by industrial garbage or those come from houses. This research is aimed at knowing the suibility of the debit capacity of drainage system and the factors causing flood in drainage system III in Singaraja city. The reason why the analysis of flood was conducted is because flood often appears in this location, and in this city there are also : (1) area of water source called Mumbul (source of fresh water or municipal waterworks). If the flood flows into this area, it will be worrying that the water will be polluted and the water pump will be broken, (2) market, (3) shopping area, and (4) housing. This research was conducted since March until June 2008 at drainage system III in Singaraja city around Tasbih street, Anggrek street, Leli street, Kenanga street, Flamboyan street, Tukad Mumbul, and A.Yani street. To know the debit capacity of the drainage system (Qs) and factors causing flood in drainage system III in Singaraja city, the analysis using mathematical model was conducted, in this case drainage dimension, debit surface running of water (Qp), and flood debit (Qb) were used as the input. Meanwhile, the factors influencing why the society threw garbage into the drainage were analyzed based on the descriptive method. The result of the research shows that the capacity the debit at Tasbih street, Leli street, Anggrek street, A. Yani Street, Flamboyan street, as well as Tukad Mumbul have been over the capacity, while the capacity of drainage debit at Anggrek and Kenanga Street have matched with planned condition (environment condition), with the Qs=74,66 m3/second; Qp=115,68 m3/second; Qb=6,79 m3/second. From the mathematical model analysis we got contribution of debit caused by change of environment (Ql)=45,27 m3/second and the debit caused by social behavior (Qm)=6,35 m3/second. The act of society that brings effect to flood is the act of throwing garbage in disposal area and this causes the increase of water debit until 3,37 m3/second; keeping the garbage in an empty place causes the increase of 0,56 m3/second; and directly throwing garbage into the drainage (upper course) causes the increase of 2,25 m3/second. Factors affecting society throwing garbage into drainage are : lack of disposal area, no punishment for those who break the rule (28,57%), the society’s view on dirty place of drainage system (71,43%) and the permissive society to the rule of throwing garbage (71,43%).

The rate of growth and development of Denpasar city increases the demand for land to supply the needs of urban facilities and infrastructure. This affected to the increase of conversion of vegetation coverage into built-up land cover. The conversion of the vegetation coverage impacts on urban environmental quality which is increase the rate of air temperature. The purpose of this study is to examine the impact of vegetation coverage change on the air temperature change in Denpasar city in year of 2003, 2009 and 2015. Remote sensing and regression statistic method were used in this study. The results showed that the decrease of vegetation coverage influenced the increase of air temperature in Denpasar city. Statistically, the correlation can be projected on the equation y = 31,295-0,078x, where x and y are vegetaton coverege and air temperature respectively. This equation shows that decresing of 1% vegetation coverege will increase 0,078 oC of air temperature. The effort to conceder in responding to the temperature rise that occurred in Denpasar is increasing the number of green open space. Based on the classification value of vegetation coverage and air temperature of Denpasar City, there are three categories of priority areas for green open space development that is high, medium and low priority. The development of green open space in each priority area can be adjusted to the characteristics of land use.
