Abstract

Rembagan River is the main tributary of the Bedadung River in Cangkring Village, Patrang District, Jember Region. Various community activities in the Rembagan River area such as bathing, washing, defecating and urinating as well as agricultural activities will produce domestic and agricultural waste. These wast can cause river water pollution, especially water quality degradation. then the research needs to be done an analysis of the capacity of the Rembagan River in receiving pollution costs. The purpose of this study is to find out how much the ability of the Rembagan River to accept the burden of pollutants using the Streeter-Phelps method. Streeter-Phelps modeling takes into account two phenomena, namely the process of measuring dissolved oxygen (deoxygenation) and the process of increasing dissolved oxygen (reaeration). The results obtained from these calculations are oxygen drop curves determined on the basis of oxygen deficit values. The average values of deoxygenation rate and reoxygenation rate were sequentially 1.58931 mg/L/day and 10.09982 mg/L/day. So that self-purification can run well which means the water quality of the Rembagan River was still relatively good. This can be seen in the DO model pattern that goes up in each segment. The actual DO of 5.6760 mg / L was greater than the DO standard of class III quality of 3 mg / L. It can be interpreted that the Rembagan River still has a remaining DO of 2.676 mg / L and was still able to accept pollution cost of 18.8 kg/day. Keywords:  pollution load, Rembagan River, river capacity

Abstract

The Mayang River in Jember Regency has a length of approximately 145.50 km which is the longest river and can irrigate an area of 5,860 hectares. The use of the Mayang River by the community can produce waste, both domestic waste, agricultural waste, and livestock waste. Waste that enters directly into river bodies can cause a decrease in river water quality and can create a pollution load. Therefore, the measurement of the load capacity of the Mayang River was conducted. Mayang River water samples were taken using the grab sampling method, while the river's capacity was determined using the Streeter Phelps method. The results showed that the average value of the Mayang River pollution load was 219,483 kg/day. Some of the parameters used to determine the carrying capacity of the river are the daily deoxygenation rate of 0.137 mg/L and the dailyy reaeration rate of 1.097 mg/L. It has a critical point (tc) of 0.186, a critical distance (Xc) of 4.753 km, and a critical deficit (Dc) of 0.281 mg/L. Based on these parameters, it is concluded that the Mayang River can accommodate a pollution load of 1.5 kg/day and can carry out proper purification. Keywords : grab sampling method, Streeter Phelps, the deoxygenation rate, the reaeration rate

Abstract

Irrigation water quality of has an essential roles in growing crops by farmers. Agricultural crops can produce superior products if they have good irrigation water quality. Irrigation water quality index (IWQI) is a method to evaluate the quality of irrigation water. This research aim at applying the IWQI in the Sukorejo Secondary Channal to determine suitable plants within the command area with the criteria of tolerance relative to salt. The research was performed by measuring some parameters including the content of Na+ (sodium), Cl– (chloride), HCO3– (bicarbonate), electrical conductivity (EC), and sodium adsorption ratio (SAR), as well as soil permeability. Results of this study showed that the Sukorejo Secondary Channal delivering irrigation water IWQI value of 61.54. Measurements also revealed the soil has a moderate to high level of permeability. Recommendation that can be given is the use plants with moderate amounts of water consumption with moderate tolerance to salt levels. Recommended plants according to IWQI value include corn, soybean, wheat, rice, tomato, cabbage, tobacco, mustard greens, celery, lettuce, papaya, pineapple, pumpkin, peanuts, cucumber, broccoli, tomato, cabbage, eggplant, spinach, potato, watermelon, radish. Keywords: Alkalinity, IWQI, Plants, Salinity, Water quality

Abstract

Okra is famous as super food sources that prevent diabetes and reduce cholesterol. To meet the increasing demand for okra, it is necessary to develop plantation for okra cultivation. In this sense, land suitability analysis for okra plantation is needed as base information to develop the plantation development strategies. This study aimed to identify the okra plantation development strategies in Jember Regency. The strategies involved the technology recommendations needed to improve land conditions. Land suitability evaluation parameters were analyzed using ArcGIS software. The results of the analysis were used to determine internal and external factors in the SWOT (strengths, weaknesses, opportunities, and threats) analysis to determine the technology needed. Results showed that suitable area for okra plantation was divided into class S1 (highly suitable) of 56.85%, and class S2 (moderately suitable) 43.15% of the area. Moreover, based on SWOT analysis the proposed technology strategies for 7 sub districts were in the quadrant II, meaning had weaknesses. Increasing compost as fertilizer was recommended to increase N, K, and P in the soil as well as to increase soil solum. In addition, irrigation and drainage system was proposed to solve problems regarding rainfall. Recommendation to reduce sloping area included terracing development. Keywords: GIS, Land suitability analysis, Okra (Abelmoschus esculentus L.), Plantations development strategies, SWOT.

Abstract

Mayang River in Jember Regency has a strategic role in fulfilling people's lives and is a source of water for 79 irrigation areas with a total area of 16,471 hectares. Community use of the Mayang River has the potential to provide input of organic material from waste which can reduce river water quality. The aim of this research is to analyze the spatial distribution of water quality parameters, namely TSS, TDS, pH, DO and BOD. This research uses multiple linear regression techniques to determine the value of the distribution or spatial distribution of Mayang River pollution, as well as identifying water quality variables that are correlated in each region. The research results show that water quality parameters that have a strong correlation are pH (r = 0.74), DO (r = 0.72) and TSS (r = 0.65), moderate correlation with BOD parameters (r = 0.48) and low correlation with BOD parameters. TDS parameters (r = 0.25). Based on the analysis results, it is known that water quality parameters are correlated with different activities in each region. The results of this research can be used as a strategy for monitoring water quality in the Mayang River to control the impact of human activities in the surrounding area. Keywords: Multiple Linear Regression, Spatial Distribution, Water Quality.

Abstract

Water quality is a key indicator related to the sustainability of living things in a watershed. However, human activities have led to a decline in the water quality caused by industrial, domestic and agricultural waste. This study aims to predict the pattern of TDS parameters at unsampled points through a geostatistical approach, namely Kriging. Experimental measuements were conducted in the Bedadung River, Jember Regency, especially in a segment of Patrang to Wuluhan sub-districts. Currently, the river is classified as Class 3, which is below the standard, one of the water quality parameters is TDS (Total Dissolved Solid). The TDS estimation results were obtained in the range of 48.26 mg/L - 175.52 mg/L. The predicted value of TDS using the kriging method at unsampled points resulted in an RRMSE value of 8.40 %. This study revealed that the water quality of Bedadung River from Patrang to Wuluhan sub-districts was still below Class 2 standards, emphasizing the need for continuous monitoring and improvement efforts. Keywords: Ordinary kriging, River water quality, Semivariogram, Total dissolved solid.
