Gunung Sewu’s karstic aquifer characteristic of fracture-fissure water conduit leads to pollution problem in the water resources. One main source of water used is the Baron Spring. This study aims to analyze the water quality of the Baron Spring toward the land use in the catchment area and provide recommendations for spatial planning and water management in certain area. This research used spatial analysis of GIS and water quality was analyzed by Pollution Index. The results showed that the Baron Spring was in a mild contaminated state with amount of TSS was 97,1 mg/L, bicarbonate 96 mg/L, total coliform 210 MPN/100ml, and total oil and fat 2 mg/L which have exceeded the water source quality standards. Those results are related with the land use in the catchment area where settlement is dense in the upstream, also because of the distribution of settlement and sinkhole in the middle-part of catchment. In coping with the contamination and pollution several strategies are urged to be designed and implemented. Strategies comprised by two approaches, socio-cultural and spatial approach. Each of the approaches is linked and should not be separated. Management of catchment including stakeholder involvement and spatial planning are essential to be considered.

The Unda River (Tukad) is the second largest river in Bali Province after the Ayung River. The Unda River has been used for various activities, such as tourism activities for white water rafting and agricultural irrigation activities. In addition, Unda River water is planned to be used as a raw water source in the planned construction of the Bali Cultural Center (PKB) which is planned to be built in the lower reaches of the Unda River. Therefore, it is necessary to conduct research related to the water quality of the Unda River, especially in the Lower Unda River. Water quality analysis refers to class II water quality standards according to the Bali Governor Regulation Number 16 of 2016. Meanwhile, the analysis of water quality status uses the pollution index (IP) according to the Decree of the Minister of the Environment Number 115 of 2003. The results of the analysis show that water quality parameters that exceed the highest quality standard is downstream (sampling point 3) with 4 (four) parameters, namely Total Dissolved Solid (TDS), chemical oxygen demand (COD), total coliform and fecal coli. While the sampling points 1 (one) and 2 (two), the parameters that exceed the quality standard are total coliform and fecal coli. In addition, the results of this study also show that the pollution index value downstream is increasing, where at sampling point 1 which is a DAM location has a pollutant index of 3.78 (light pollution) and at sampling point 2 of 6.27 (moderate pollution) and at sampling point 3 of 7.67 (medium polluted).

The problem in this study is related to the number of developments, especially those aimed at their designation, which is not by the existing regional spatial plan. This is because many developments are located in disaster-prone areas, coastal border areas, and protected areas. This also triggers changes in land use that are quite large from time to time. This study aims to determine the use of utilization with a regional spatial plan. This study uses quantitative methods to determine developments based on data in the Sangihe Islands Regency, analyzing image data and knowing the level of suitability of land use with the RTRW. The method of analysis in this study uses a method of spatial analysis based on geographic information systems (GIS) using supervised classification, scoring, weighting, overlay. The variables in this study include land use, spatial planning, and adjustments. The results show that the land area in the Regional Spatial Plan is suitable for land use in particular for an area of ​​3,202.65 hectares and not suitable for an area of ​​17,946.03 hectares from the total area of ​​the existing land use.

Abstract One of seventeen points of Sustainable Development Goals (SDGs) is to provide clean water for at least 80% of the global population in 2025. Rural populations living surrounding Lake Toba water catchment area still utilize the lake water for daily use regardless of the susceptible decreasing water quality. This paper describes anthropogenic aspects affecting the water quality of Lake Toba that is consumed as the drinking water source by surrounding residents. The research used a quantitative approach by interviewing 130 household representatives from 3 regencies around the lake to calculate the water consumption and evaluate the water quality in 2018. In addition, this research also assessed the residents' behavior in managing household waste and wastewater. The result showed that the average water consumption is 86,93L/person/day. The majority of the respondents barely treat the water and feel satisfied with the water quality based on its color, turbidity, taste, and odor. On the contrary, the respondents have not adequately treated their domestic waste and household wastewater before being released to the lake, contributing to water pollution. Although most respondents are satisfied with the water quality, it is still needed to perform proper water treatment because the water quality of Lake Toba is reported as slightly up to heavily polluted by the Ministry of Environment and Forestry in 2019.

Abstract. Contributing Catchment Area Analysis (CCAA) is a spatial analysis technique that allows estimation of the hydrological connectivity of relatively flat catchments and the effect of relief depressions on the catchment rainfall-runoff relationship for individual rainfall events. CCAA of the Southern River catchment, Western Australia, showed that catchment contributing area varied from less than 20% to more than 60% of total catchment area for various rainfall events. Such variability was attributed to a compensating effect of relief depressions. CCAA was further applied to analyse the impact of urbanisation on the catchment rainfall-runoff relationship. It was demonstrated that the change in land use resulted in much greater catchment volumetric runoff than expected simply as a result of the increase in proportion of impervious urban surfaces. As urbanisation leads to an increase in catchment hydrological connectivity, the catchment contributing area to the river flow also becomes greater. This effect was more evident for the most frequent rainfall events, when an increase in contributing area was responsible for a 30–100% increase in total volumetric runoff. The impact of urbanisation was greatest in sandy catchments, which were largely disconnected in the pre-development conditions.

Reservoirs are formed through the artificial damming of a river valley. Reservoirs, among others, capture polluted load transported by the tributaries in the form of suspended and dissolved sediments and substances. Therefore, reservoirs are treated in the European Union (EU) as “artificial” or “heavily modified” surface water bodies. The reservoirs’ pollutant load depends to a large extent on the degree of anthropogenic impact in the respective river catchment area. The purpose of this paper is to assess the mutual relation between the catchment area and the reservoirs. In particular, we focus on the effects of certain land use/land cover on reservoirs’ water quality. For this study, we selected twenty Polish reservoirs for an in-depth analysis using 2018 CORINE Land Cover data. This analysis allowed the identification of the main triggering factors in terms of water quality of the respective reservoirs. Moreover, our assessment clearly shows that water quality of the analysed dam reservoirs is directly affected by the composition of land use/land cover, both of the entire total reservoir catchment areas and the directly into the reservoir draining sub-catchment areas.

Land use change is one of the effects of population growth and increased human activities. Land use change that overlooked the rule of ecosystem sustainability has a propensity to adversely affect the environment, including the decline of water quality. Kali Madiun is a sub-watershed of Bengawan Solo Watershed that allegedly endured the impacts of land use change. This study aimed to investigate the impacts of land use change on the water quality index of Kali Madiun Sub-watershed. Land use change analysis was done by overlay analysis of spatial data including the maps of land use in 2010 and 2015. Samples were the surface water in the upper, middle and lower part of Kali Madiun Sub-Watershed. Water quality analysis was carried out by comparing the results of water quality parameter assessment based on Government Regulation No. 82 of 2001, while water quality index was figured out by an assessment based on the Decree of the Minister of Environment No. 115 of 2003. The results indicated that during the five years observation, there were land use changes in the upper, middle and lower part of Kali Madiun Sub-watershed. Several parameters increased in 2010 to 2015, namely: TDS, BOD, COD, nitrate, detergents, oils and greases. Pollution index shifted from slightly polluted in 2010 into moderately polluted in 2015. We propose a strategy to solve these problems by the involvement of stakeholders and the participation of local community in managing both domestic and industrial wastes. Also, it should be supported by palpable regulations related to land conversion. Furthermore, it is expected that the effort will reduce the potential of pollution and improve the water quality.

Berdasarkan data UPTD Puskesmas Sabang Tahun 2017 terdapat kasus Kejadian Luar Biasa (KLB) penyakit diare dengan penderita 45 orang dan 1 orang dinyatakan meninggal, pada tahun 2018 data penderita diare terdapat 24 orang (Januari-Juli). Tujuan penelitian ini adalah Untuk mengetahui hubungan kualitas air sumur gali dengan kejadian penyakit Diare di Desa Montop. Penelitian ini merupakan penelitian dalam bentuk survey yang bersifat observasional dengan metode pendekatan cross-sectional, yaitu suatu penelitian yang dilakukan dengan pengamatan sesaat atau dalam suatu periode waktu tertentu dan setiap subjek studi hanya dilakukan satu kali pengamatan selama penelitian. Hasil penelitian menunjukan bahwa hasil uji kualitas air bersih berdasarkan parameter E. Coli masih memenuhi syarat kesehatan sesuai dengan Permenkes 416 Tahun 1990 tentang air bersih. Sementara, untuk parameter Total Coliform terdapat hasil yang tidak memenuhi syarat kesehatan pada Lokasi SGL 3 dan SGL 5 artinya analisis secara deskriptif ada hubungan sumber air utama dengan kejadian diare karena terdapat 2 SGL yang Total Coliform nya Tidak Memenuhi Syarat Kesehatan. Diarrhea is one of the diseases that is still the biggest health problem in Indonesia. Diarrhea can be caused by several factors, environmental factors and the quality of clean water. Therefore, environmental conditions and the quality of clean water that is not good influences the onset of the disease. Montop Village is one of the villages in the North Bulagi sub-district of Banggai Kepulauan Regency whose people consume water sourced from the Gali Well. Based on data from Sabang Health Center UPTD in 2017 there were cases of Extraordinary Events of diarrhea with 45 patients and 1 person was declared dead, in 2018 the data of diarrhea patients there were 24 people (January-July). The purpose of this study was to determine the relationship of dug well water quality with the incidence of diarrheal disease in the village of Montop. This research is an observational survey with a cross-sectional approach, which is a study conducted with observations for a moment or in a certain period of time and each subject of study was only made one observation during the study. The results showed that the water quality test results based on E. Coli parameters still met health requirements in accordance with Permenkes 416 of 1990 concerning clean water. Meanwhile, for the Total Coliform parameter, there were results that did not meet health requirements at SGL 3 and SGL 5 locations, meaning that the descriptive analysis was related to the main water source with the occurrence of diarrhea because there were 2 SGLs whose Total Coliform did not meet health requirements.
