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.

Abstract

Pisang cavendish menjadi jenis pisang yang banyak diminati di pasar internasional, sehingga untuk meningkatkan volume ekspor pisang Indonesia, jenis pisang yang tepat untuk di budidayakan adalah pisang cavendish. PT.XYZ menjadi salah satu perusahaan yang turut membudidayakan pisang cavendish dengan tujuan ekspor, yang terus melakukan perluasan area perkebunan termasuk di wilayah DAS Sampean Baru, Kabupaten Bondowoso, Provinsi Jawa Timur. Perluasan dilakukan dengan sistem kemitraan bersama Pemerintah Kabupatern Bondowoso dan kelompok tani. Namun, belum dilakukan penilaian kesesuaian lahan untuk budidaya tanaman pisang cavendish. Oleh karena itu, kajian ini bertujuan  melakukan evaluasi kesesuaian lahan dan rekomendasi perluasan area penanaman di wilayah DAS Sampean Baru. Evaluasi kesesuaian lahan dilakukan dengan membandingkan kondisi parameter kriteria terkini dengan kriteria kesesuaian lahan untuk tanaman pisang cavendish. Parameter input adalah jenis tanah, tutupan lahan, curah hujan, dan topografi yang dianalisis menggunakan  ArcGis 10.3 melibatkan 7 parameter kriteria kesesuaian lahan tanaman pisang cavendish. Hasil menunjukkan DAS Sampean Baru memiliki 2 kelas kesesuaian lahan yaitu S1 (sangat sesuai) sebesar 15.303,99 ha (25,05%) dan S2 (cukup sesuai) 45.789,31 ha (74,95%). Perluasan area budidaya pisang cavendish dapat mengoptimalkan lahan – lahan dengan status S2. Kondisi tersebut memberikan kesimpulan bahwa secara keseluruhan wilayah DAS Sampean Baru sesuai untuk budidaya tanaman pisang cavendishnamun perlu diperhatikan bahwa kondisi kelas S2 memerlukan beberapa upaya penanganan untuk mencegah dampak dari keberadaan faktor pembatas.

Abstract

Efficient use of irrigation water is essential because water availability often does not meet crop requirements. In response, compost application is a potential solution, as it improves soil structure and enhances water-retention capacity. Nevertheless, the water-binding capacity of compost varies depending on the source of animal manure. To address this, the study aimed to evaluate the effectiveness of compost made from cattle, poultry, and goat manure in improving water retention in Andosol soil and supporting tomato growth as a biological indicator. The study used Andosol soil mixed with compost at application rates of 25% (500 g), 50% (1000 g), and 75% (1500 g), along with a control without compost. A two-factor completely randomized design with three replications was applied, and measured parameters included moisture content, media weight, water-holding capacity, pH, plant height, and leaf number. Results showed that the treatment using 1500 g of goat manure compost combined with 500 g of Andosol soil produced the highest water-holding capacity, making it the most effective option for irrigation water conservation. In contrast, cattle manure compost yielded the best tomato growth and productivity. Overall, these findings demonstrate that selecting the appropriate manure-based compost can enhance soil water retention and improve irrigation efficiency.
