Besides positive results, the rapid development and growth of Denpasar City has also brought some problems to the Government of Denpasar City, for example the emergence of housing complexes that did not meet health standards and requirements. This problem can cause negative impacts toward the health condition of city residents, especially in the form of diseases influenced by environment factors such as acute respiratory infections (ARI). Based on that phenomena this study was carried out to examine the causal relationship between home sanitation factors (ventilation, natural lighting, humidity, temperature, population density, and air pollution) and the event of acute respiratory infections (ARI) in the working area of Public Health Centre IV of Denpasar Selatan District, in Denpasar City. This study had an observational nature and employed a cross-sectional design. Based on data analysis applied, this study belong to analytical studies. Population size of this study was 5,777 and covered all inhabited houses in the working areas of Public Health Centre IV of Denpasar Selatan District. Sample of 97 houses were taken using proporsional stratified random sampling. Statistical tests shows that: (1) the quality of house sanitation has a significance value p = 0.000 (sig p <0.05), (2) house ventilation has a significance value = 0.162 (sig p>0.05, (3) natural lighting has a significance value p=0.002 (sig p<0.05), (4) Room humidity has a significance value p=0.003 (sig p<0.05), (5) Room temperature has a significance value p=0.491 (sig p>0.05), (6) house population density has a significance value p=0.123 (sig p>0.05), (7) Air population in the house has a significance value p=0.001(sig p<0.05).

Erosion is a form of land degradation is very serious in Koloh Pasiran watershed. This condition perceived more severe by the fact that the understanding of the process of saving the natural resources of forest, soil and water have not received maximum attention. This is evidenced by the presence of illegal logging, forest fires around the area of the watershed during the dry season and flooding during every rainy season. Therefore, the research conducted with the aim to: 1) determine the level of erosion and soil and water conservation planning in the Koloh Pasiran watershed, 2) determine the land capability class in Koloh Pasiran watershed and 3) to plan land use capability classes based on erosion rate. Observations and sampling of soil samples for prediction of erosion, soil conservation and classification approach according, planning based on common land unit. This land unit maps obtained from the land use maps overlay by slope, soil and land use maps done by estimating the magnitude of the erosion equation USLE (Universal Soil Loss Equation) of Wischmeier and Smit (1978). Determine land capability class with land capability classification approach according Arsyad (1989). Land use planning and soil and water conservation in addition to using USLE equation also uses land capability classification according Arsyad (1989). The results show the level of erosion prediction calculation slight to very severe erosion. Mixture of garden soil with a 2% slope erosion rates relatively slight. Dry land with a slope of 2% classified as severe erosion and the shrub land with a slope of 2-3% erosion classified as severe to very severe. While in secondary forest land and primary forests with a slope of 2-25% relatively slight erosion. Land capability class in Koloh Pasiran watershed can be classified into class IV (3 units of land), class V (5 units of land), class VI (1 unit of land) and VIII (2 units of land). The limiting factors are: (e) the slopes are steep and severe erosion rate and (s) low water holding capacity. Direction of land use for high density mixed garden with bench terrace with good construction, dry with good bench terrace construction and given a booster plants around the lip of land, shrub land used for community forestry, agroporestry and natural forests, while for secondary forests and forest maintained primary sustainability

Buleleng Regency has the potential to develop a hybrid cantang grouper aquaculture business. However, the cultivation business in Buleleng Regency on average does not have its own waste disposal site. Ammonia is the most dangerous content of aquaculture waste for marine life. Ammonia can cause an increase and accumulation of levels of inorganic compounds that can trigger toxins for some organisms to increase the prevalence of pathogens and certain fish diseases in the waters. One treatment that can be done in reusing wastewater is to make wastewater as a place to live fish by processing using filtration and disinfection methods, namely using silica sand media, zeolite, activated charcoal, palm fiber and ultraviolet (UV). The purpose of this study is to test the feasibility of water before and after filtration, and determine the best type of water for the Cantang hybrid grouper nursery. The method used in this research is a quantitative method using RAL (Completely Randomized Design) with three treatments and four replications. After that an analysis using ANOVA is used to determine the effect of the treatment given on the parameters tested. In the study, the water quality after filtration and disinfection treatment was better than the water quality before filtration and disinfection treatment, it can be seen in the ability of the filtration and disinfection method in reducing ammonia, nitrite and total bacterial colonies by 41.30%, 79.75%, and 76.92%, and increase the water pH and phosphate levels to 7.50 and 27.36%. In addition, the use of filtration and disinfection water can increase the survival of fish by 7.14% compared to using sea water. The survival of groupers using filtration and disinfection water is 100% while sea water is only 92.86% and wastewater is 57.14%. Filtration water can reduce bacteria compared to sea water and waste water. Except for the salinity, ammonia and phosphate parameters which still do not meet the standards.

As a regional income barn, the Nusa Penida Tourism Area needs to be managed comprehensively by involving all available resources, by encouraging new thinking about managing tourism that synergizes with environmental sustainability in the sustainable environment of the Nusa Penida Tourism Area. Tourism can increase economic growth but create a burden on the environment, so that Nusa Penida tourism becomes environmentally friendly tourism to support the development of green tourism. Progress in tourism impacts the environment, causes social and cultural changes in society and impacts the carrying capacity of land and water from the massive tourism development in Nusa Penida. For this reason, it is necessary to formulate a model of environmental management that is relevant and has been developed.This study uses a systems approach with the Interpretative Structural Modeling (ISM) method to formulate an environmental management model in the Nusa Penida Tourism Area. This method can be used to help a group, in identifying contextual relationships between sub elements of each element that forms a system based on ideas / structures or determinants in a complex problem (Saxena, 1992).The environmental management model in the Nusa Penida was formed based on government initiatives by involving all stakeholders as representatives of the Nusa Penida community and involving other elements such as non-government organizations and universities. In the management of the environment, institutional arrangements that specifically handle the environment and tourism of Nusa Penida must be formed with the government as the initiator and formed in a participatory manner. The recommended model of environmental management needs to be applied carefully and continued with the formation of institutions by involving the affected community sectors in Nusa Penida's environmental management and tourism.Keywords: tourism, model, management, environment, Nusa Penida

Central Kalimantan covers an area of 157,983 km2 with more than 2,000 km2 of tropical peatlands, which is one of the buffer regions of Indonesia's new capital government city. However, the sad story is the conversion of about one million hectares from peat swamp forests (PSF) to rice fields occurred in the mid-1990s, so called the Mega Rice Project (MRP). Since then, forest and peatland fires become an annual event due to high level of degradation under the climate change symptoms such the frequent of the El Niño event. In very strong El Niño of 2015, Indonesia has returned to the world spotlight in relation to the fires and the haze crisis. The most fire prone area was recorded in the iconic Tumbang Nusa, Pulang Pisau Regency and its adjecent areas. However, the thick haze had covered almost the entire province. There are the dis-adventages impact during more than two months. Therefore, this study was to investigate what are the causes and the impacts of this disaster at the site level. This research location was focuses on three regencies and one city namely Pulang Pisau, Kapuas, Katingan and Palangka City. The method was a Focus Group Discussion (FGD) with key figures representing eight clusters of village communities. This method is also supported by statistical, hotspots and spatial data for additional analysis. The result are only two villages with very high average of hotspot and eight with high average of hotspots in Pulang Pisau and Kapuas Regency. Further, the FGDs in seven villages showed that there were three main clusters that caused forest-land fires, namely natural factors, human factors and village policy / regulation factors. The villages study that were affected by the fire in 2015 showed there were three main impacts namely on people, environment and capital. This result is a foundation of cause-effect factor for further Root Cause Analysis to find out the options for fire prevention and management in climate change mitigation efforts.
