“…In the Class II quality standard, the TDS parameter is 1000 mg/L, and in 2018–2020 it decreased, see Exhibit 6. Suppose the high TDS value in water can be caused by the remnants of inorganic materials and molecules caused by wastewater, such as detergents, water‐soluble surfactants, and soap molecules (Sulistiawati et al., 2020). Water with high TDS levels causes scale in household appliances, and the water tastes terrible like metal (Sharma & Bhattacharya, 2017).…”

This study aimed to analyze water quality and control water pollution in the Pucang River in Sidoarjo Regency. The method was used to identify water quality of the 11 parameters and compared them the Government Regulation number 22 of 2021 about water quality standards in Indonesia. Secondary data from 2018 to 2020 were used in this study. Determination of water quality status using the pollution indices method attached in Decree of the State Minister of the Environment number 115 of 2003.Analysis of water pollution control strategies using strengths, weaknesses, opportunities, and threats approach. The condition of the water quality of the Pucang River in 2018-2020, based on the water pollution parameter test, experienced a decrease in the rate indicated by the presence of parameters that exceeded the quality standard. Determination of the quality status of water quality in 2018-2020, there was an increase in water quality marked by the rise in the pollution indices value where the water quality was moderately polluted heavily polluted. The conclusion is that the water quality of the Pucang River in 2018-2020 has decreased from the moderately polluted category to the heavily polluted, and the condition of river water cannot be used for its designation.

“…The environmental conditions support seaweed cultivation in Harvest Season (June -July) (Table 8). For instance, the strong water current of (0.11 -0.17 m/s) (Table 8) could hold a better condition for seaweed cultivation [23] by providing a barrier and nutrition that is essential for seaweed development. The degree of water clarity reveals that the light, which is essential for seaweed photosynthesis, can penetrate through the water (around 2.00 -4.6 m) (Table 8).…”

“…A high degree of differences in the total dissolved solid parameter was also observed (Table 8). However, it is still considered suitable, below the lowest threshold < 80 ppm [23]. The suitable depth for seaweed cultivation must be less than 10 meters above the sea ground [23], and both seasons show a roughly suitable condition (Table 8).…”

“…However, it is still considered suitable, below the lowest threshold < 80 ppm [23]. The suitable depth for seaweed cultivation must be less than 10 meters above the sea ground [23], and both seasons show a roughly suitable condition (Table 8). For the acidity, as previously stated by Poncomulyo et al [23], the optimum acidity (pH) for seaweed cultivation is around 7.3-8.2, and both seasons fall under this range (Table 8).…”

Indonesia is the largest producer of seaweed contributed by coastal communities, but they still live in precarious conditions. To bolster the seaweed cultivation and alleviate poverty, a coastal community's empowerment was studied in Salabangka archipelagoes through the evaluation of its largely produced seaweed (Eucheuma cottoni) potency (total production and investment opportunities), suitability for seaweed cultivation (environmental parameter and suitability), and local participation (interviews) in 2011. Seaweed production in Salabangka archipelagoes was estimated from 2009 to 2010 data. For the investment opportunities of seaweed cultivation, initial investments were assessed for the medium-scale semi refined carrageenan (SRC) model and the Carrageenan industry model. Subsequently, the profit and loss were projected for the upcoming five years. To estimate the investment qualification, several criteria were used, i.e., Net Present Value (NPV), Internal Rate Return (IRR), Net Benefit Ratio (Net B/C), Pay Back Period (PBP), and Profitability Index Methods (PI). The factors that influence the local participation and perceptions of coastal communities in Salabangka archipelagoes were analyzed based on the degree of perception and participation obtained from interviews in substation sites. The seaweed potency reveals a good prospect indicated by the increase of seaweed production and profitable investment. The environmental condition and qualifications support the suitable habitat for seaweed cultivation. Local participation shows a good indication of the support of the coastal communities. In the future, the government must secure the policy, allocate funding, and forge a partnership with the local bank to bolster the seaweed cultivation in the Salabangka archipelagoes.

“…The annual TDS uctuated between 2070 ppm at location 2 during summer to 51239 ppm at site 15 during summer (Table 1). The high concentration of TDS is caused mainly by the remnants of inorganic materials and wastewater molecules due to the anthropogenic activities around the water body (Sulistiawati et al 2020).…”

Relative effects of spatio-seasonal variations on the quantitative and qualitative status of phytoplankton in 20 sampling locations of Temsah Lake were examined during winter and summer 2018. The study reveals that the population structure consisted of 105 species from 69 genera, with an annual average of 924155 cell/L. Bacillariophyceae formed the most dominant group with 42.45% of total phytoplankton with an average of 372379 cell/L. Navicula creptocephala was the most abundant species representing 19.16% of total diatoms and 7.78% of the whole standing crop with an annual average of 376879 cell/L. The highest phytoplankton abundance was in the Northern locations. Phytoplankton density showed a negative correlation of pH, temperature and TDS and positively correlated with nutrient content such as nitrate and silicate. In general, summer showed high indices value compared to winter and the diversity index in the current study ranged in moderate pollution range. The polluted state of the aquatic ecosystem in El-Temsah Lake during summer is comparatively higher than winter during the study period. Palmer’s and diversity indices showed that Northern sites were the most flourishing and polluted sites. The study also recorded a number of tolerate algae (13 genera and 8 species), which can be used as an indicator for different degrees of organic pollution. Genus and species Palmer’s Index scores of the northern site were in the range of ≥20 during summer, indicating most of the sampling locations showed probable to confirmed high level of organic pollution.
