Abstract

Development on each sector would gived negatife effect for environment quality, such as agriculture development to be agroindustry. One of the negative effect of intensification effort through using of pesticide is donate contaminant to water. Identification of suitability agriculture landuse and water polution level by pesticide using is the one effort to save a resource from intensification agriculture efforts. The methods that we was used are analysis spatial for determined of suitability agriculture landuse and contamination indeks for describe how far the water contamination. The result showed that the area where suitable for agriculture in Batu is 1333, 54 Ha or 6,78% and the evaluation result showed there is unsuitable landuse in existing condition is 25,67% from total area, and 32,05% for spatial planning condition. The increased of unsuitable landuse on spatial planning caused by agriculture sector development which the area for agriculture more larger than the land capability, planing for agriculture area is 3289, 76 Ha. Contamination level for water river in Brantas from good condition with IP value is 0.92 on Sumber Brantas and the higest level in Ngujung’s river with IP value is 245,39 with weigh level status. Agriculture intensification efforts also have contribution to reduction water quality on the upper of Brantas.

Abstract

Buleleng Regency has the potential to develop a hybrid cantang grouper aquaculture business. However, the cultivation business in Buleleng Regency on average does not have its own waste disposal site. Ammonia is the most dangerous content of aquaculture waste for marine life. Ammonia can cause an increase and accumulation of levels of inorganic compounds that can trigger toxins for some organisms to increase the prevalence of pathogens and certain fish diseases in the waters. One treatment that can be done in reusing wastewater is to make wastewater as a place to live fish by processing using filtration and disinfection methods, namely using silica sand media, zeolite, activated charcoal, palm fiber and ultraviolet (UV). The purpose of this study is to test the feasibility of water before and after filtration, and determine the best type of water for the Cantang hybrid grouper nursery. The method used in this research is a quantitative method using RAL (Completely Randomized Design) with three treatments and four replications. After that an analysis using ANOVA is used to determine the effect of the treatment given on the parameters tested. In the study, the water quality after filtration and disinfection treatment was better than the water quality before filtration and disinfection treatment, it can be seen in the ability of the filtration and disinfection method in reducing ammonia, nitrite and total bacterial colonies by 41.30%, 79.75%, and 76.92%, and increase the water pH and phosphate levels to 7.50 and 27.36%. In addition, the use of filtration and disinfection water can increase the survival of fish by 7.14% compared to using sea water. The survival of groupers using filtration and disinfection water is 100% while sea water is only 92.86% and wastewater is 57.14%. Filtration water can reduce bacteria compared to sea water and waste water. Except for the salinity, ammonia and phosphate parameters which still do not meet the standards.

Abstract

Groundwater and surface water are important sources of clean water which require an effective management. The use of groundwater and spring as exemplified by Batu City case – as part of Brantas watershed upstream – serves as raw water as well as clean water source for Batu City and Malang City population. Contamination of surface water and groundwater affects clean water supply as indicated by increasing nitrate, TDS, and E. Coli concentration. The study aims to analyze the vulnerability level of groundwater contamination by using spatial multicriteria analysis with DRASTIC index. The DRASTIC index is measured from some parameters such as surface water depth to water table, net recharge, aquifer media, soil media, topography, impact of vadose zone, and hydraulic conductivity to evaluate groundwater vulnerability. The results show that Batu City performs low vulnerability (86.93%) and medium vulnerability (13.07%) levels. The dominant factors affecting the level of vulnerability are groundwater levels, slope, and geological conditions across regions. Even though the DRASTIC modelling cannot specify the contamination levels of the different sources, this method is useful to identifying high-level contaminated land uses, managing water resources, and conserving groundwater sources.

Abstract

Starting in 2000, the growth of population and industries sector rapidly increased in Brantas Hulu’s river. This phenomenon brought environmental issues since most of industries dispose of their waste including organic-based pollution to the surrounding river. It contaminates the river and lowers the water quality. Minimum assessment on water contamination in Brantas River attracts the research on the area. The study aims to assess water quality on Brantas River based on several parameters: water quality pattern using QUAL2Kw model, determine of pollution level using pollutant index and pollution load capacity. The research relied on a quantitative description by measuring pollution level and calculating acceptable pollution load. The result shows that 10 from 12 sampling areas produced low pollution levels, while the others are moderate level of pollution. The most pollutant found in the Brantas River were BOD, nitrate, ammonia and phosphate. Simulation results from QUAL2Kw model accounted for 10.7% of error rate.

Abstract

Sungai Brantas memiliki fungsi penting bagi provinsi Jawa Timur, 60% pengairan lahan produksi beras berasal dari aliran sungai ini. Observasi lapang menunjukkan bahwa terdapat banyak bangunan rumah mendekati area sungai bahkan sampai melewati batas, hal ini juga terjadi khususnya di area Kota Malang. Rekaman laporan indeks kualitas air di Jawa Timur Tahun 2015 tercatat berada di angka 52.51 dengan status sangat rendah dan terus menurun dengan angka 50.75 pada tahun 2016 dengan status yang waspada. Berdasarkan kondisi diatas sangat penting untuk memonitor kualitas air dan menentukan kapasitas sungai dalam menerima polusi secara berkelanjutan. Metode atau model yang dapat digunakan untuk memprediksi kualitas air secara simultan sepanjang sungai adalah Qual2E. Aplikasi ini menghitung kestabilan profil air permukaan dan mensimulasikan perubahaan pada kondisi aliran sepanjang aliran sungai. Tujuan dari studi ini adalah mensimulasikan kondisi kualitas air berdasarkan parameter BOD dan DO dan menentukan kapasitas beban polusi. Hasil simulasi dengan model Qual2E pada parameter BOD dan DO dengan hasil validasi didapatkan bahwa model dapat diterima karena x2 hitung < x2 tabel yaitu pada BOD sebesar 2.456 dan x2 hitung pada DO sebesar 1.439 dengan nilai R2 masing-masing parameter sebesar 0.7424 dan 0.6439, sehingga terdapat kedekatan korelasi antara hasil lapang dengan model yang dilakukan. Perhitungan beban pencemaran pada Sungai Brantas menunjukkan bahwa titik 6 yang terletak pada Kecamatan Blimbing dan titik 9 pada Kecamatan Kedungkandang menerima beban pencemaran yang melebihi daya tampung atau beban maksimum yang dikehendaki, Perlu perhatian khusus untuk pembuangan limbah yang ada di perairan pada titik tersebut agar dapat ditanggulangi dengan cepat dan tidak memperburuk kondisi yang ada. Penerapan peraturan Menteri Lingkungan Hidup No. 01 Tahun 2010 tentang tata laksana pengendalian pencemaran air perlu dimonitoring.

Abstract

The diversity of activities along the Balangan river causes waste disposal, which contributes to an increase in pollution load in the Balangan river. The purpose of this study is to predict the water quality conditions spatially using IDW method, and to determine the relation among distance and water quality status. In the whole location, the results showed that the pollution load capacity was exceeded, the levels of BOD5, COD, Sulfide, Iron, Manganese and Phosphate were parameters that had exceeded the quality standard. The pattern of water quality decreases in the downstream area, especially at BOD5 and COD levels. While the levels of TSS, Nitrate, Nitrite, Ammoniac, Iron, Manganese, and Detergent showed a temporary pattern of decline and showed an increase again. Phosphate levels showed a temporary increase and then there was a decrease again afterwards. Based on the sampling location the distance between the starting point and end point is 12 km, the prediction of the distribution of water quality using IDW shows that at a distance of 1-6 km shows a stable water quality pattern, a distance of 7-10 has improved water quality and 11-12 has decreased water quality.

Abstract

Cattle manure contains high organic matter, so that this material is commonly used as plant nutrients in a form of organic fertilizer. In order to get a better understanding on the use of cow manure, the objectives of this research are (1) to determine the influence of liquid waste and solid livestock as fertilizer on soil quality and (2) to study the effect of both liquid and solid fertilizer on coffee plant growth. In this research, Completely Randomized Design (CRD) was employed as a research design, while data analysis was conducted using ANOVA. The F statistical test was applied to measure whether all independent variables could influence the dependent variable by using 5% and 1% (Alpha) degrees. The results showed that one time application of livestock wastewater improved C-organic chemical properties, N, P, CEC, Ca and Mg while soil chemical properties of pH, K, Na decreased. Two times application of livestock liquid fertilizer treatment improved soil chemical properties pH, N total, Ca, Mg and saturation bases. As for solid waste, one time treatment increased chemical properties of pH, C organic, N total, Ca and saturation of the base. The two times treatment could improve soil chemical properties of pH, N. total, P, Ca, Mg, base number and base saturation. Liquid waste fertilizer also found to provide significant effect on plant height and coffee plants quality. Additionally, (3) solid waste (compost) was found to have a significant effect on plant height, plant height rate and number of buds.

Abstract

The river is a part of the surface water resource which is very potential for living. The quality of river water is greatly influenced by land use and human activities in the catchment area. Increasing the number population in Banyuwangi Region and its activity has the potential to reduce the water quality of the river, especially in the Sukowidi and Bendo catchment area, therefore it is necessary to assess the water quality. This research was conducted to identify the source of pollutants and determine the pollution index, status of water pollution, as well as to determine pollution load capacity. The data analysis was carried out quantitatively and graphically, and spatially with the QUAL2Kw and the Inverse Distance Weighted (IDW) by using  ArcGIS 10.4.1. Land use on the two rivers is slightly different, that is rural, suburban, and urban areas. The pollution sources in the study area were point source and non-point source. The results showed that the pollution status of the Sukowidi River was "Light Polluted" and the high pollutant load carrying capacity had total suspended solids and nitrates. Meanwhile, in the Bendo River, the pollution status is not polluted yet and the pollutant load carrying capacity is on the quality standards. These findings provide valuable information and guidance for the Banyuwangi Regency government to decide on land use policy.
