In order to maintain the environmental carrying capacity of coastal tourism, this research was conducted to determine the condition of river water environmental pollution in the Petitenget beach area and pollutant source activities. Determination of water quality is carried out by analyzing the water quality taken at several sampling points in the four rivers that lead to the Petitenget beach. Determined the pollution index value (IP) of the physical chemical and biological pollution parameters. The results showed that the four rivers that flow into the Petitenget Beach area had been contaminated with indications of pH, BOD, COD, ammonia, Coliform and E. coli which exceeded water quality category III class quality (PerGub Bali No 16 Year 2016). The four rivers are included in the criteria of severe contamination. The four rivers have experienced physical damage or structural changes that have very high discharge fluctuations both in quantity and quality. Slimy basic structure, smelly and slum aesthetic waters. While the indication of the impact of pollution is waste water which is directly discharged into the river from hotels, restaurants, homestays, commercial centers and settlements.

The use of Agrochemicals for increasing the agricultural products are commonly applied on agricultural soils, especially the soil used for cultivatif cabbage in the area of Kintamani-Bangli, Province of Bali. Agricultural soils used for cultivatif cabbage in Kintamani area commonly apply inorganic fertilizers and synthetic pesticides for increasing the products. However the use of these agrochemicals tends to uncontrol and causes the soils polluted. One factor of contamination of soil is the presence of heavy metals in the soil. Intensive use of inorganic fertilizers and synthetic pesticides can lead to high levels of bioavailability of heavy metals in plants. This study intend to determine the total contents of heavy metals Pb and Cd in the agricultural soils and analyse bioavilability of those metals. The total metals was determined by the use of digestion method involving reverse aquaregia (HNO3:HCl, 3:1) and the bioavailability of the metals was determined by applying single extraction including HCl and EDTA extractions. The results show that the total contents of Pb and Cd in the soils were 4,1261 ± 0,1113 – 14,5923 ± 0,3790 mg/kg and 0,8803 ± 0,0259 - 0,9425 ± 0,0195 mg/kg respectively. The bioavailable metals of Pb and Cd in the soils was 31,14% - 42,53% and 78,70% - 80,73%, respectively.

The process to supply the drinking water will also be expensive due to the decreasing quality of water it self. Some chemical substances are needed in high quantity to produce healthy water from Badung River, such as chlorine and aluminum sulphat (Al SO4). This is because the polutants of water in Badung River is really high. To decrease the use of the amount of chemical subtances and to avoid the side effect of chlorine on water which is highly organic, so this research was done through the use of biofilter. This biofilter is like bee-hive which is made from plastic. This micro-organism would scatter the organic substance and ammonia. In this case, iron (Fe) and Manganese (Mn) would be oxydized by the air and water from the blower. On the next step, the measurement of the content in each organic substance, iron, manganese, nitrate, nitrite, ammonia was done on the streaming water and the water that was out from biofilter reactor. In every parameter, the sampel was taken periodically from 1 to 6 hours hydrolic-setting time. The testing of using aluminum sulphate and the needs of chlorine was done in every 1 to 6 hours hydrolic-setting time. The result of the research told us that for 6 hours hydrolic- setting time could decrease 38.78% the organic substance, iron ( Fe) 41.93%, manganese (Mn) 55.32%, ammonia 75.40%, nitrite 55.32%, but nitrate increased up to 53.85%. The increase of nitrate is still tolerable based on the law of governor (Pergub) Bali No. 8 year 2007. The use of chemical substance, in this case aluminum sulphat could be decreased up to 10 ppm and chlorine (gas) could also be decreased until 10 ppm.

Sindhu Beach is part of the Sanur beach area. Sanur area is one of 11 strategic national tourism areas in Bali. Beach tourism activities have the potential to cause degradation of coastal ecosystems. Ecosystem changes can be determined using bioindicators. This study aims to determine the condition of the Sindhu Coast waters ecosystem based on seagrass diversity and macrozoobenthos as indicators. This research was conducted in November 2019 at Sindhu Beach. Seagrass observations and macrozoobenthos sampling were carried out at four stations with three replications at each station. Data and samples were collected using the quadratic transect method. Eight species of seagrass were found in Sindhu Beach with a percentage of cover between 16.33% - 63.37% and density between 1572 ind / m2 - 3314.4 ind / m2. The average value of the seagrass diversity index was 1.24, the average uniformity index was 0.78, and the average dominance index was 0.32. Types of macrozoobenthos found were 23 species with abundances ranging from 2.33 ind / m2 - 28.33 ind / m2. The average value of macrozoobenthos uniformity index is 1.50, the average diversity index is 0.68 and the average dominance index is 0.36. Based on the index value shows that the waters of Sindhu Beach are in good condition or there is no ecologically significant pressure.

In developing countries, including Indonesia, household waste is a multidimensional problem, namely that in its completion it involves many aspects so that the application of community-based solutions is needed. Waste banks are one solution to reduce household waste. A waste bank is a community-based waste management system that actively engages the community. The surrounding neighborhood can exchange trash into other forms that have economic value. The waste bank that is a model for other waste banks in Indonesia is the Bank Sampah Induk Bantul, which was established in 2008 and has used an online-based waste management system as of 2015. An online-based waste management system is one of the efforts to facilitate the activities of managers and customers of waste bank. However, its use in Bank Sampah Induk Bantul is still limited. Therefore, a preliminary study was conducted to determine the extent to which the online waste management system is used, so that appropriate actions can be taken to increase the use of the online system. This study uses a qualitative approach, namely field observations, semi-structured interviews and informal discussions. The results of this study indicate that the use of online-based waste management systems is not optimal because the online system does not accommodate the activities and problem solving faced by the Waste Bank. Besides, in the online-based waste management system, there are several features needed by the Waste Bank, but their use is limited due to technology acceptance from the Waste Bank management which is still relatively low.

The conventional rice cultivation of Traditional Flooding (TF) seems to be wasting the water and potentially polluting the soil and water due to improper chemical fertilizers and pesticides management (Nguyen et al., 2007). System of Rice Intensification (SRI) is one of the innovative rice cultivations with the principle of single seed replantation and intermitten irrigation (IWMI, 2007). The experiment was conducted to analyze the macro nutrients, total microbes, and the rice production by combinations of nutrient and pest management in TF and SRI system. This study applied a nested experimental design with two factors. The first factor was the cultivation system that consisted of two levels (TF and SRI), and the second factor was nutrient and pest management consisted of three combination levels (synthetic nutrient and pest management/P1, organic-synthetic nutrient and organic pest management/P2, as well as organic nutrient and pest management/P3). These combinations were nested to TF and SRI. Data were analyzed by ANOVA. It is found that P1 showed the highest growth and production in SRI and TF. The numbers of the height, tillers, total grains and the weight of seed per pot in SRI respectively are 87.33 cm, 22.17 tillers, 1179.50 grains, and 32.17 g, meanwhile in TF respectively are 78.75 cm, 17.50 tillers, 1063.33 grains and 29.00 g. P3 shows the highest content of macro nutrients and total microbes in SRI and TF, respectively the contents of C, N, P and K of P3 in SRI are 6.82 % (very high), 0.31 % (moderate), 155.69 ppm (very high), and 1804.85 ppm (very high), meanwhile in TF respectively are 6.52 % (very high), 0.25 % (moderate), 52.60 ppm (very high), and 530.79 ppm (very high). The total microbe contents of P3 in SRI and TF respectively are 2.7 x 108 CFU/g and 3.7 x 108 CFU/g. It is concluded that both in TF and SRI system (1) P1 shows the highest growth and production and (2) P3 shows the highest content of macro nutrients and total microbes. Furthermore, it is suggested that in the future the rice cultivation system should be done in a wider scale and multiple planting seasons in order to be able to precisely measure the significant difference of the rice cultivation system towards the rice growth and production.
