Abstract

The research has the objective to know the water quality of Bengawanjero River in terms of the quality of physics and chemistry, and compare the test result with the standard quality of water in government rule of Indonesian Republic No. 28 year 2001. Research use Survey-Qualitative and Quantitative Descriptive method. Qualitatively measured parameters were odor, color, taste, depth, current velocity, brightness. Descriptive quantitative parameters were temperature, turbidity, TSS, TDS, Conductivity, Current velocity, Salinity, DO, BOD, CO2, Ammonia, and pH. Color parameters obtained few turbid, ground smell odor and slightly salty taste. Physical parameters; brightness, depth, current velocity, turbidity, TSS, TDS, conductivity of every station fulfill criteria or as classified normal in accordance with water quality standard of No.82 year 2001 for class II. Based on the quality of the Bengawanjero River waters at every station of the chemical parameters; salinity, BOD, CO2, ammonia, and pH fulfill the water quality standard criteria. The condition of the Bengawanjero River in terms of physical and chemical parameters is normal quality. In the Wates, however, the dissolved oxygen value is lower i.e 3.86 than the permitted quality standard with BOD and turbidity values higher than others were possible by organic factor. Keywords: Water Quality, Physical and Chemical Parameter, Bengawanjero River ABSTRAK Penelitian mempunyai tujuan untuk mengetahui kualitas air sungai Bengawanjero ditinjau dari kualitas fisika dan kimia, dan membandingkan hasil uji dengan standar baku mutu kualitas air PP No 28 tahun 2001. Metode yang digunakan adalah metode Survei-Deskriptif Kualitatif dan Kuantitatif. Secara Kualitatif diukur parameter: Bau, warna, rasa, kedalaman, kecepatan arus, kecerahan. Deskriptif kuantitatif adalah parameter : Suhu, Kekeruhan, TSS, TDS, Konduktivitas, Kecepatan arus, Salinitas, DO, BOD, CO2, Amonia, dan pH.. Parameter warna didapatkan agak sedikit keruh, berbau tanah dan rasa agak sedikit asin. Parameter fisika; kecerahan, kedalaman, kecepatan arus, kekeruhan, TSS, TDS, konduktifitas tiap stasiun memenuhi kriteria atau tergolong normal sesuai dengan baku mutu air PP No.82 tahun 2001 untuk kelas II. Berdasarkan kualitas perairan sungai Bengawanjero pada tiap-tiap stasiun dari parameter kimia; salinitas, BOD, CO2, amonia, dan pH memenuhi kriteria baku mutu air. Kondisi sungai Bengawanjero ditinjau dari parameter fisika dan kimia masih tergolong kualitas yang normal. Akan tetapi pada dusun Wates nilai DO lebih rendah yaitu 3,86 dari baku mutu yang diizinkan dengan nilai BOD dan kekeruhan lebih tinggi dibanding lainnya dimungkinkan oleh faktor bahan organik.

Abstract

The growth of fungi can be influenced by nutrients is in the environment, With the additional two kinds of nutrients from sugar plant waste of molasses, and waste of the pepaya taken the filtrate. Both of these wastes contain sugar which is needed by fungal microorganisms to grow and reproduce. The fungus Aspergillus niger, Hansenulla sp, Trichoderma viride, and Candida sp have a synergy interaction in a media. This study aims to learn in the growth of fungal cell populations as cell masses in potato dextrose media with the addition of two kinds of nutrients. The method used in this study was a two-population mean test with 2 treatments, namely the first treatment with the addition of sugarcane drops, and the next with the addition of papaya fruit filtrate, consisting of 11 replications, with incubation for 3 days. The analysis used was the T test and the analysis results obtained were significant, which was shown from P> 0.05. The mass of fungi cells in the addition of nutrients from sugar factory waste was greater than that of papaya fruit filtrate waste

Abstract

Pollution is a problem for most of the territorial waters in Indonesia including the territorial waters on the coast of Seger Kuta, Central Lombok. One way to analyze the quality of waters in coastal areas is by analyzing water quality in the form of parameters, physics, chemistry, and biology. This method can provide information about the condition of a waters. The purpose of this study is to identify the condition of the quality of the waters of the Seger Coast before and after the Bau Nyale tradition based on physical, chemical and biological parameters. This research was conducted in February 2020 at three research stations and the results were compared with sea water quality standards based on the Minister of Environment Decree No. 51 of 2004 concerning Sea Water Quality Standards and other references. The results showed in general the quality of coastal waters before and after the Bau Nyale tradition at Seger Kuta beach, Central Lombok is still classified as good or lightly polluted waters. Plankton found in the study site before the Bau Nyale tradition there are 8 genera derived from 4 plankton groups namely Diatomae 5 genus, Dinophyceae 1 genus, Cynophiceae 1 genus and Cilliata 1 genus. The number of genera from each observation station before the Bau Nyale tradition ranged from 6-8 genera with a total abundance of 95-227, whereas after the Bau Nyale tradition there were 8 genera originating from 3 plankton groups, namely 6 genera Diatomae, 1 genus Mastigophora and 1 Cynophiceae . The number of genera from each station after the Nyale Odor tradition ranges from 7-8 genera with a total abundance of 62-171.

Abstract

Water is a very important human need and no life can exist without air. Human needs are generally obtained from various sources, both from groundwater, surface water and rainwater. Ubalan is a hamlet located in Ngajum District, Malang Regency. The location is under the foot of Mount Kawi - Malang which has a natural spring and is generally channeled by the surrounding community to fill artificial ponds and also used by the community to meet their daily needs. The use of spring sources is generally very diverse, including for drinking water, fisheries, conservation and as a tourist attraction. Water indicators such as total coliform bacteria and Escherichia coli. Regarding this statement, it is necessary to carry out a microbiological test to test for total coliform and Escherichia coli bacteria at the Ubalan spring, Maguan Village, Ngajum District, Malang Regency, which is a tourist attraction location that is never empty of visitors. The research method used is survey method and descriptive laboratory analysis. To take samples of air sources carried out randomly. The test results for Total Coliform and Escherichia coli bacteria in West Sumatra Mata Air Ubalan, Maguan Village, Ngajum District, Malang Regency, showed that the MPN results index was at station 3 (0.273) station 2 (0.188) and the lowest was at station 1 (0.138). The analysis is related to the level of the presence of total coliform and E. coli bacteria with pollutant source factors that are thought to come from human activities around the source, community behavior and the distance factor between air sources and exhaust locations. Correlation of research results obtained by the presence of total coliform bacteria and Escherichia coli in the air source with the relationship of factors between the supporting bacteria showed (p value = 0.188) which means it did not have a significant effect.
