“…In Indonesia, The condition of freshwater is always an issue that threatens its sustainability and becomes a national problem (Soeprobowati et al 2016). For example, the problem of Rawa Pening Lake in Central Java Province is the occurrence of eutrophication, sedimentation, water quality degradation, and blooming of water hyacinth (Soeprobowati et al 2017;Hidayati et al 2018). The same problem also occurs at other lakes of national priority, including Lakes of Toba, Maninjau, Singkarak, Kerinci, Tondano, Limboto, Poso, Tempe, Matano, Cascade Mahakam Semayang-Melintang Jempang, Sentarum, Sentani, Rawa Danau, Batur (MoE, 2010), Telaga Warna Dieng (Soeprobowati et al, 2017) and several reservoirs such as Saguling, Cirata, Jatiluhur, Lahor, Karangkates, and Sengguruh (Chrismadha et al, 2011).…”

Batujai reservoir is located in Central Lombok Regency, Indonesia. The government and local people use it for hydropower generation, drinking water, agricultural irrigation, fish farming, and tourism. The phenomenon of growing population and increasing industrial activities in the catchment area of Batujai reservoir always result in the discharge of various pollutants into the aquatic environment and cause the blooming of water hyacinth over almost 30% of the reservoir area. The aim of this study was to determine the water pollution index of Batujai reservoir. The samples were analysed for the following parameters: pH, temperature, DO, COD, BOD, TSS, and heavy metals. The research was done by using purposive sampling method and determination of water quality status with STORET method based on Government Regulation No. 82/2001. The measurement results show that the physical and chemical parameters of the Batujai reservoir water do not exceed the quality standard are the temperature (29 to 32°C

“…DTA merupakan hulu dari sungai-sungai yang mengalir ke Danau Rawa Pening, sehingga pola pemanfaatan lahan dan aktivitas ekonominya akan memengaruhi kualitas, kuantitas dan kontinuitas air yang masuk kedalam danau. Danau Rawa Pening merupakan salah satu danau prioritas yang menghadapi persoalan eutrofikasi, penutupan eceng gondok (Eicchornia crassipes), dan sedimentasi cukup parah (Girsang et al, 2019;Hidayati et al, 2018) serta ketersediaan air (Nugroho, 2017) dan kualitasnya (Aida & Utomo, 2017;Heriza, Sukmono, & Bashit, 2018;Piranti, Rahayu, & Waluyo, 2018). Meskipun eceng gondok dianggap sumber masalah, tetapi ada masyarakat yang menganggap eceng gondok bermanfaat terutama untuk peningkatan pendapatan (Ningsih et al, 2019).…”

Rawa Pening Lake is one of the priority lakes facing severe eutrophication and sedimentation problems. Agriculture is one of the problems in Rawa Pening Lake, even though community welfare is the government's policies. For this reason, the development of the economic sector in Rawa Pening catchment area must have advantages, yet information on this is still neglected and limited. The study aims to analyze the leading economic sectors in the Rawa Pening catchment area. The study used the Klassen Typology method to determine the pattern and structure of the economy and the Location Quotient method in determining the economic sector that has a comparative advantage in each sub-district and analysis of sectoral contributions. The data used is secondary data and field observations. The results showed that Bawen Subdistrict was a developed but depressed area, relying on the manufacturing industry sector. Rapidly developing districs (Tuntang, Jambu, Sumowono, and Ambarawa) rely on all economic sectors. The lagging districts (Getasan and Banyubiru) relly on the primary sector. Leading sectors of each district differ depending on resources and comparative advantage. Leading economic sector contribute relatively significantly to economic development in the lake Rawa Pening catchment. The development of the economic sector will be better directed to leading economic sector so that it can attract sector that are not base, especially in the limited resources and allocation of development budgets. In addition, Location Quotient analysis can be used for analysis of areas with natural boundaries such as catchments or watersheds.

“…Suwanda Karya Mandiri, 2015). The lake provides water for irrigating about 24,000 hectares of rice fields and for generation of 20 Mega Watt of hydroelectric power (Hidayati et al, 2018b). Since 2003, the government of Semarang regency has begun to use lake water as a source of raw water to meet industrial and household needs of freshwater.…”

“…It is now becoming increasingly clear that the changes in lake ecosystems not only undermine their ecological integrity but also alter the supply of ecosystem services resulting in significant consequences for the environment and human wellbeing (Reynaud and Lanzanova, 2017). Eutrophication and sedimentation are currently and in the foreseeable future will remain wicked issues of lake management for developing countries including Indonesia (Haryani, 2014;Henny and Meutia, 2014;Hidayati et al, 2018a;Thornton et al, 2013). In responding to this problem, the Indonesian government has recently issued a restoration policy of 15 lakes, one of which is Lake Rawapening.…”

The aim of this study is to estimate willingness to pay (WTP) of local residents, by applying the contingent valuation method as a surcharge on their water bill, for a given improvement of lake ecosystem for ensuring the sustainability of freshwater supply in term quantity and quality as demanded by public water utility. The survey was conducted in Semarang regency involving 116 respondents in three villages that received clean water services from Lake Rawapening. The mean of WTP was estimated to be 6,055.54 rupiahs (0.433 US$) per month for each household, approximately equivalent to 9.26% of the average monthly water bill of the households. The results revealed that younger and educated respondents, households with higher income and with fewer members were, on average, were willing to pay more. This study also demonstrated that households’ ownership of groundwater wells was a hindering factor for contributing to improving lake’s ecosystem. The results of this study can assist decision-makers to understand the public demand for improved Lake Rawapening ecosystem and to formulate better environmental policies.
