Abstract

Wonocolo Village is a traditional old oil well mining tourism area in Kedewan District, Bojonegoro Regency. This existence affects water quality because it is one of many factors causing groundwater pollution. The purpose study is to determine the distribution pattern of pollution such as iron, manganese, and zinc due to oil mining. Moreover, the study predicts the pattern of distribution of pollution in groundwater over a certain period of time. The method used for this study is groundwater modeling (MATLAB). Thus, determination of sampling based on SNI 6989.58:2008 with 3 (three) sampling points. The determination of the distribution pattern uses the parameters such as Iron, Manganese, and Zinc. The simulation results of the 2-dimensional distribution model and in the range in the next 18 years and 50 years. The prediction result for iron content is still in good condition. Meanwhile for manganese content and zinc content will be polluted after 50 years with a detected distance of ± 1150 m and ± 1400 m respectively from the contaminant source point.

Abstract

Any changes always take effect to the environment either positive or negative, it is no exception developments in technology. In addition to bringing benefits to the human development, technology has always had a negative impact, actually thrash or waste from obsolete technology as the results of the process productions or side product. The mobile phones waste is one of the electronic waste that need to be awareness. Electronic waste processing in particular mobile phones as one of the new problems in the waste management, and it will be an ice mountain problem for developing countries because generally they have limited technology, insufficiency of financial and lack of human resources in the management of electronic waste that electronic trash left to accumulate for granted. Indonesia as a developing country need to strengthening regulatory, economic support and technology transfer of electronic waste management from developed countries to suppress pollution caused by electronic waste disposal carelessly.

Abstract

Laundry waste is one of the wastes that is wasted when it is disposed of continuously and continuously. This results in the destruction of aquatic ecosystems, especially fish. This study aims to determine the value of LC50-96 hours of laundry waste on tilapia fish (Oreochromis sp.). This study begins by knowing the parameters of BOD, COD, TSS, NH3, and detergent at the stage of Range Finding Test and Acute Toxicity Test. In addition, pH, temperature, and DO parameters were also tested every day. After that, acclimatization was carried out for 7 days without feeding the fish. Then continued with the range Finding test stage for 96 hours with variations of 0% (control), 5%, 10%, 20%, 40%, 60%, 80%, and 100%. The range obtained in the range Finding test stage is 20%. So that the variations in the acute toxicity test stageused include 6%, 9%, 12%, 15%, and 18%. After observing fish mortality approaching 50%, then these results were analyzed using Microsoft Excel. The LC50 value obtained in this test is 60002,5.

Abstract

Abstract The clean water that is usually used by the residents of Berbek Village comes from well water. The quality of the dug well water is unknown. Water of unknown quality can bring a negative impact on Berbek villagers' health. Most of the well water in Berbek village has the physical characteristics of the water, the color and smell of which are not good. This study determines the water quality of dug wells in Berbek village and identifies the status of well water quality by the Pollutant Index method. Samples taken as many as five points were taken by the duplicate method. Parameters tested include pH, temperature, turbidity, Total Dissolved Solid, Iron, Manganese, Hardness, Lead, and Total Coliform. This study resulted that the parameter showed the quality of well water above the quality standard, namely Temperature, TDS, Mn, and Total Coliform. The well water quality status in this study was categorized as “Heavy Polluted” water. Abstrak Air bersih yang banyak digunakan warga Desa Berbek bersumber dari air sumur gali. Air sumur gali tersebut tidak diketahui kualitasnya. Air yang tidak diketahui kualitasnya dapat memberikan dampak buruk bagi kesehatan warga desa Berbek. Air sumur di desa Berbek sebagian besar memiliki ciri fisik air warna dan bau yang kurang baik. Tujuan dari studi ini guna mengetahui kualitas air sumur gali desa Berbek serta mengidentifikasi status mutu air sumur gali dengan metode Indeks Pencemar. Sampel yang diambil sebanyak lima titik diambil dengan metode duplikat. Parameter-parameter pengujiannya meliputi pH, suhu, turbidity, Total Dissolved Solid, Besi, Mangan, Kesadahan, Timbal dan Total coliform. Hasil dari penelitian terhadap beberapa parameter kualitas air sumur hasilnya diatas standar mutu yaitu Temperatur, TDS, Mn, dan Total Coliform. Status mutu air sumur pada penelitian ini dikategorikan sebagai air “Tercemar Berat”.
