      Abstract: Monitoring water sources is essential to ensure the quality and quantity, one of which is in the Titab Reservoir. The purpose of the study was to assess the water quality and amount of pollution in the Titab reservoir in terms of physical, chemical, and microbiological characteristics, as well as the NVC of Tawes (Barbonymus gonionotus) fish. There are five station points for water sampling and 10 test parameters related to water quality. Data analysis compares test results with second-class water quality standards (Bali Governor Regulation No. 16/2016), IP value (pollution index), and NVC with Furton's equation. The test results obtained that the water in the Titab reservoir has a temperature of 28.97oC, TSS (0.18 mg/L), pH (8.82), BOD (3.22 mg/L), COD (16.70 mg/L), DO (6.77 mg/L), Total Phosphate (0.12 mg/L), Nitrate (0.19 mg/L) and Fecal Coliform (960 MPN/100 mL), the IP value was 1.39, and the NVC was 1.65. Thus, the pH, BOD, and Fecal Coliform levels of the Titab reservoir water did not match the specified limits, although the other parameters satisfied the water quality norms. The Titab reservoir's water is classed as mildly contaminated with the NVC value of tawes fish, referring to the Titab reservoir's polluted water. Keywords: Tawes Fish, Titab Reservoir, Water pollution, Water quality.

      Abstract: Batur is the largest lake in Bali which has the potential to experience pollution due to the high activity in the body and the surrounding environment. This condition indicates the need for serious management efforts to maintain water quality. This study aims at analysing the water quality, status of the water quality of Lake Batur and also formulate a strategy for controlling water pollution in Lake Batur. The water sample analysis method was carried out in two ways, namely in situ method and laboratory testing. The feasibility level of the results was matched with the Class 1 Water Quality Standard based on the Bali Governor Regulation number 16 of 2016, for the status of the water quality determined by the Pollution Index Method according to the Decree of the State Minister of the Environment No. 115 year 2003. In determining the control strategy, the force field analysis method was applied. The results of the study, there were several parameters that exceeded the quality standard ranging from 18.33-23 mg/l. In addition, the DO content at some points was also not classified as lightly polluted where the highest IP value is Brother with a value of 2.07. The pollution control strategy of Lake Batur produced based on force field analysis was increasing innovative socialization to the community, increasing the promotion of Lake Batur conservation, providing training and entrepreneurial skills as well as providing small-scale business capital assistance, synergizing government policies and programs and forming a pollution control unit. Keywords: water quality; pollution index; control strategy.

      Abstract: Endek is one of the fabrics that are in demand by local and foreign people. The distinctive pattern of this endek cloth continues to develop while still paying attention to the authenticity of the endek motives from Bali so that it is easily recognized by the public, however, in its production, it produces waste that causes environmental pollution therefore it needs to be managed. One of the easy and efficient textile waste management is a bioreactor by utilizing local culture. Local cultures are indicated as indigenous microorganisms originating from the waste itself. The purpose of this study is to analyze the effectiveness of local cultures in bioreactors in improving wastewater quality and analyze the effectiveness of using local microbial cultures in bioreactors for treating endek wastewater. This study applied a quantitative approach with experimental methods. The processing begins with the growth of biofilms to determine the biomass profile using the Mixed Liquor Suspended Solid (MLSS) method, then the color waste water is stored in an anaerobic reservoir for 24 hours then tested and then processing, later it is inundated for 1 hour before parameter measurement. The parameters tested were COD levels, color content and pH. Based on the results of the study, the optimum MLSS value obtained in the seeding process was 4490 mg/L on the 7th day and the biofilm growth biomass profile of 3240 mg/L on the 22nd day. The utilization of local microbial culture in the bioreactor in this study was effective in reducing the color content parameter by 77% at processing times of 384 and 408 hours, and decreasing pH was only effective at processing time of 6 hours and reducing COD was not effective.

      Abstract: Water is an essential requirement for human life. Maintain water availability, both in terms of quality and quantity, in relation to the surrounding environmental conditions. The socio-cultural conditions of the people of Nusa Penida are very much influenced by the presence of water, even social conflicts occur because of the water crisis. The main problem with drinking water raw sources is the availability of water sources which continues to decline from year to year, while water demand continues to increase due to population growth. Areas that have limited water resources will cause economic resources to be used to meet water needs. As an area that has limited water resources, Nusa Penida has springs that are mostly difficult to reach and access by the community. Two springs with quite large discharge are Penida Spring and Guyangan Spring which have been distributed to the community and to fulfill tourism needs. This study aims to determine the feasibility of Penida and Guyangan Springs as a source of drinking water based on Governor of Bali Regulation Number 16 of 2016 concerning Environmental Quality Standards and Standard Criteria for Environmental Damage and to determine the potential sources of pollutants for these two springs. This study uses a quantitative approach combined with primary data sources from direct observations in the field and uses secondary data sources from literature and previous research. The results showed that the Penida and Guyangan Springs were in good condition and met quality standards. Potential sources of pollutants from Penida Springs come from residential activities and tourism activities, while Guyangan Springs does not have pollutants because they are located in a place that is difficult to reach and is in the bowels of Nusa Penida Island.

      Abstract: Many people use surface water for their daily needs. Reservoir water in Yeh Kori Embung is used for various purposes; however, there has not been an inspection of the quality and pollution index that allows contamination of the reservoir. This study aims to evaluate the quality and level of pollution of Yeh Kori Embung Water in Jungutan Village, Karangasem Regency. A descriptive design with a mix-method approach was used in this study. Water samples were taken at five different stations for two periods. Furthermore, physical, chemical and biological examinations are carried out and adjusted to quality standards. The results show that pH (5.2 – 5.4) is in the acidic category and does not meet the requirements while temperature (25.3oC), TSS (32.02 mg/L), DO (6.56 mg/L), BOD ( 1.36 mg/L), COD (10.4 mg/L), NO3-N (4.38 mg/L), Total P (0.021 mg/L), and Fecal Coliform (75.08 MPN/100mL) meet quality requirements. The pollution index (IP=1.085) is classified as lightly polluted. Yeh Kori Embung water does not meet the requirements of class two water quality and requires periodic evaluation and inspection. Keywords: pH, Pollution level, Reservoir, Water quality, Yeh Kori.

      Abstract: The goal of the study was to analyze the water quality of dug wells based on Bali Governor Regulation No. 16 of 2016 and Regulation of the Minister of Health of the Republic of Indonesia No.492/Menkes/Per/IV/2010, which analyzes the quality status of dug well water and its distribution based on the Pollution Index (IP) value and community behavior in Sanur Kauh Village, South Denpasar. Purposive sampling at three stations with three repeats was used to determine the sample. Temperature, color, taste, odor, TDS, turbidity, pH, DO, BOD, COD, Nitrate (NO3-N), Phosphate (PO4), Chloride (Cl-), Iron (fe), E. Coli, and total coliforms were among the parameters measured in situ and ex situ (laboratory). Questionnaires and interviews with respondents who used dug well water were used to collect data on perception and behavior of components (households, business actors and/or activities, farmers, and the government), which were analyzed using a Likert scale and binary model. Surfer and GIS were used to map the water from an excavated well. The results of the analysis of the quality of dug well water exceeded the Class I Water quality standard set by Bali Governor Regulation No. 16 of 2016 for BOD, COD, phosphate, nitrate, iron, total coliform, and turbidity parameters, as well as the Indonesian Minister of Health Regulation No.492/Menkes /Per/IV/2010 for BOD, COD, phosphate, nitrate, iron, total coliform, and turbidity parameters Population activities, pollution sources, climate, soil type and topography, height and depth of the well all influence the water quality status of dug wells, which is classified as moderately polluted. The average community's impression of the provision of dug well water, water pollution, and waste management is positive, and the average community conduct is positive.

      Abstract: Flash flood is water level increases rapidly in the river beyond flood level and occurs due to extreme weather. It's happened quickly without warning. The Klagison Watershed in Sorong City has grown rapidly and often had flooded. Settlements dominate almost on watershed areas and there are many hills that are deforested due to mining activities upstream. This study aims to examine the morphometric conditions and to analyze the spatial distribution of the potential flash flood in the Klagison Watershed of Sorong City based on morphometric analysis. GIS is used to obtain morphometric parameters such as linear, relief and aerial parameters. The correlation coefficient between each morphometric parameter was calculated using Pearson Correlation. Determination of potential flash flood areas using the priority zone formula. The result shows that the Klagison watershed has high erosion potential and large runoff based on morphometric analysis. This can be seen in the high value of the texture ratio (T) and low Constant channel maintenance (C) so that the runoff volume is also large. The Lof value in all sub-watersheds is small, which means that surface runoff will quickly to the channel. The flash flood potential in the Klagison watershed is very low (Sub-watershed 1 and Sub-watershed 5), moderate (Sub-watershed 3 and Sub-watershed 4), high (Sub-watershed 2) and very high (Sub-watershed 6 and Sub-watershed 7). It means that Sub-watershed 2, Sub-watershed 6 and Sub-watershed 7 need management priorities related to disaster mitigation. Keywords: flash flood; morphometry; watershed

      Abstract: Mining and nickel processing activities in Pomalaa, Kolaka Regency have an impact on the condition of coastal waters. Several researchers who have conducted research in the area stated that the Pomalaa coast has been polluted by the presence of nickel metal so that there is an initiative to reduce the impact of Ni in the waters by bioremediation of the microalgae Chlorella vulgaris and Spirulina platensis. This study aims to analyze the growth of microalgae types C. vulgaris and S. platensis cultured on media containing nickel with different concentrations and also to determine the ability of microalgae to reduce nickel heavy metals at different concentrations. This research was carried out at the Fisheries Laboratory of Haluoleo University , while the AAS (Atomic Absorption Spectrophotometric) analysis was carried out at the Kendari Environmental Laboratory UPTD Laboratory on January – May 2021. The results of the analysis showed that there was a significant difference in the growth density of microalgae cells (C. vulgaris and S. platensis) which were given the treatment/concentration. Ni different. The absorption capacity of C. vulgaris ranged from 0.73 to 4.97 mg/l, while s. platensis ranged from 0.082 – 2.11 mg/l. C. vulgaris is superior in reducing nickel because C. vulgaris can live in polluted water conditions. Keywords: Bioremediation; Nickel; C. vulgaris; S. platensis.

      Abstract: Monkey Forest Ubud is located in the Padang Tegal Village, Ubud District. The area of ''''the tourism forest is about 12.5 ha. Tourism activities at Monkey Forest Ubud tend to be mass tourism activities. This study aims to measure the position of the effective carrying capacity of Monkey Forest Ubud based on biotic and abiotic variables, perceptions of tourism actors (tourists and management) towards tourism activities, condition of facilities and infrastructure and management of Monkey Forest Ubud, as well as alternative strategies for the realization of environmental sustainability and tourism. The method used to analyze the carrying capacity of the environment according to Cifuentes, drafting alternative sustainable management strategies for Monkey Forest Ubud with QSPM analysis. The results of the carrying capacity analysis show the ECC of 257 people/day. The average tourist visit in 2010-2019 reached 1,784 people/day, exceeding the ECC value indicates a threat to the biotic and abiotic factors that affect it. Alternative strategies resulting from the QSPM analysis for the realization of sustainable tourism with a score of 4.88 are alternative tourism in the form of educational tours in the Yadnya forest and event procurement in non-forest areas, the second strategy with a score of 4.86 is to maximize the digital marketing function, namely buying tickets online with providing daily visit quotas for tourist restrictions, the third strategy with a score of 4.66 is to increase ticket prices by 50% from normal tickets.The existence of the Ubud Monkey Forest has a positive impact on the social and economic aspects of the Padang Tegal Village community, but environmental sustainability needs to be considered, one of which is the restriction of tourist visits.

      Abstract: Banyuwedang Bay is located in the West Bali National Park (TNBB), which is part of the conservation area. There were a lot of tourism activities developed in this area, which potentially caused disruption of the surrounding water conditions. This study aims to determine the profile of various communities in the waters of Banyuwedang Bay and as initial data to see the development of these communities due to the environmental impacts of various activities in the waters and coastal area of Banyuwedang Bay. Data was collected from five observation stations including: Community structure of Plankton, Macrozoobenthos, and seagrass, and coral reef cover. Result shows that the phytoplankton community consist of 9 genera where Nitzschia sp. (Bacillariophyceae) as the dominant species found. Phytoplankton have low diversity index ranging between 0.348 - 1.411. Zooplankton diversity index also has low value 0.693 with three genera found namely Copepoda sp., Nauplius sp. and Daphnia sp. Macrozoobenthos community is composed of 17 macrozoobenthos genera, with low diversity index ranging ''between 0.562-1.809. There are only two species of seagrass, Halophila ovalis and Cymodocea rotundata, which were found in Banyuwedang Bay. Coral reef cover seems to be ranged from poor to good conditions, with 25% - 73% coverage. Based on the result, we concluded that the Banyuwedang Bay has a moderate condition to the growth of plankton and seagrass, but good for coral reefs. Periodic monitoring is needed to find out changes in conditions that can occur in Banyuwedang Bay. Keywords: Banyuwedang Bay; community structure; macrozoobenthos
