“…The model used for this situation analysis is SWOT Analysis. SWOT analysis is a systematic identification of various factors to formulate a strategy (Bajpai & Nemade, 2023;Sindhu et al, 2017). This analysis is based on logic that can maximize Strengths and Opportunities, but simultaneously can minimize Weaknesses and Threaths (Rangkuti, 2006) represented by Table 1.…”

The Batu Jai Dam functions as an irrigation facility in the agricultural areas of Penujak, Setanggor, Darek, Ungga, Ranggagata, and around Praya Barat District, Central Lombok Regency with an area of 3,350 ha. Water hyacinth is a dangerous weed because it grows very fast, so a model for the control and utilization of water hyacinth (Eichornia crassipes) must be carried out. One way to do this is to utilize the water hyacinth plant into a marketable product such as fertilizer, handicraft products and others. The technique of determining the location and population is done by purposive sampling method. The results of a search with a questionnaire on 50 respondents about the benefits of water hyacinth plants obtained the benefits of water hyacinth plants according to the people around the Batujai dam, namely 40% stated that the benefits of water hyacinth plants as raw materials for making fertilizer, 30% as raw materials for crafts such as sandals, bags, and other, 20% of water hyacinth plants are used as medicine and only 5% of the people consider water hyacinth plants as weeds. Whereas in extension activities with 35 participants, 48.6% stated that water hyacinth plants could be useful as raw materials for crafts, 37.1% stated that they were used as fertilizer raw materials, 3% stated that they were useful as medicine and 2% stated that they are weeds. concluded that water hyacinth plants are economically, socially, ecologically beneficial. This shows that water hyacinth plants are beneficial to the environment around the dam. Based on the results of the FGD, there were 3 important activities carried out by related agencies based on the results of counseling and interviews with the community, namely water hyacinth plants as fertilizer, as raw materials for crafts and determining the location of water hyacinth cultivation outside the Batujai Dunngan.

Aquatic macrophytes, notably the invasive water hyacinth, exhibit proficiency in nutrient removal from polluted water bodies, rendering them appealing for water remediation applications. This study investigates the potential of water hyacinth in phytoremediation, focusing on the effect of using nutrient-rich biogas slurry mixed with water in varying concentrations, i.e., 16.6, 33, 66.6, 100, and 133 mg/L for the investigation. The physiochemical properties of the liquid biogas slurry were evaluated before and after treatment with water hyacinth over eight weeks, with continuous monitoring of nutrient reduction rates. Results showcased substantial average reductions of nitrogen, phosphorus, and potassium, with a relative growth rate of 5.55%. The treatment also decreased pH, total dissolved solids, hardness, and chemical oxygen demand. The theoretical BMP of water hyacinth was determined using Buswell’s equation. Water hyacinth grown in the concentration of the biogas slurry exhibited the highest methane yield at 199 mL CH4/gm VS, along with the highest relative growth rate. This study used experimental data to create a mathematical model that describes how the relative growth of water hyacinth depends on the number of days and biogas slurry concentration (C). The model’s quality and effectiveness were evaluated using the goodness of fit (R2) and observable approaches. The polynomial model, referred to as Poly model 1, 2, is the best fit for describing the relationship between the growth percentage of water hyacinth, days, and nutrient solution concentration. In this model, C has a polynomial degree of one (normalized mean of 69.84 ± 43.54), while D has a degree of two (normalized mean of 30 ± 21.65).
