Research on the use of the spray aeration method with adsorption of cocoa rind powder to reduce iron and manganese levels in dug well water has been carried out. This study aims to make comparisons from two methods to reduce iron and manganese in dug well water. The parameters optimized in this study are the aeration time and the variation of the addition of the adsorbent mass and the adsorption time. Based on the research results, the spray aeration time for 2 hours gave the optimal percentage reduction for Fe3+ and Mn4+ metal ions, namely 98.68% and 94.22%. Meanwhile, for adsorption using cocoa pod husk powder, the optimal reduction occurred in the adsorbent mass of 0.2 grams and the adsorption time of 60 minutes for iron and manganese 96.36% and 95.15%, respectively.

The Relationship

The well is one of the source water used for bathing, washing, and drinking by the citizens in Jiken Hamlet, Rarang Village, Terara Sub-District. Poor dug well construction conditions can affect the amount of coliform bacteria contained in the dug well water. The purpose of this study is to identify the construction of dug wells and the content of coliform bacteria in dug well water and determine the relationship between dug well construction and the content of coliform bacteria. This research is analytic with a cross sectional study design. The results were obtained from 11 samples of dug wells which were observed in construction and the coliform content was known that all samples did not requirements as good dug well construction. Coliform content test results showed that as many as 5 dug well water samples did not pass the clean water quality standards. The results of data analysis with the chi-square test variable construction of dug wells with coliform content variable  showed 0,172 > 0,05, then the concluded is the dug well not suitable to use by people in that area as a source of water for daily needs.

BACKGROUND: Based on the results of laboratory examinations, initial samples taken from one of the clean water sources (dug wells) in Biringere Village, North Sinjai District, results showed that the water sample contained high enough metal ions such as Fe, Mn, hardness, and organic substances which did not meet the requirements as clean water because it still contained levels of Manganese (Mn) 1.68 mg/l. Meanwhile, for organic substances (KMnO4), it is 9876 mg/l. AIM: The purpose of the research was to determine the effectiveness of multimedia filters in improving quality of clean water from the parameters of Mn and KMnO4 in clean water sources (dug wells).. METHODS: The type of research conducted is quasi-experimental by made a filtering processing method with a “Up Flow” flow system, using media consisting of silica sand, zeolite, resin (pine resin), and active carbon in PVC tubes. The population in this study were all dug wells in North Sinjai district. The samples were dug wells located on Biringere Village, North Sinjai District. The samples examined in Center for Environmental Health and disease control of Makassar. RESULTS: The results obtained were that there was a significant change in manganese (Mn) levels of 0.49 mg/l (80.37%). Meanwhile, organic substances (MnO4) amounted to 17.38 mg/l (70.02%). CONCLUSION: Decreasing levels of manganese (Mn) in well water after going through the multimedia filter process above show that the manganese content has met the standard requirements of the Minister of Health Regulation No. 32 of 2017.

This study aims to identify the bacteria Escherichia coli in the water dug wells owned by residents on the banks of the gajah wong river, Kotagede-Yogyakarta. Bacteria Eschericia coli is one cause of diarrhea that need to know its existence to prevention of diarrhea. This research used descriptive analytics.The results showed, all the well water as a positive contain Eschericia Coli. The closer the distance between the well and the river, the higher the content ofEschericia.Coli. 50% of dug well water sampled is still feasible for consumption because the content of Escherichia coli is still less than 50 MPN/100ml

ABSTRACTIndonesia has an abundant quantity of natural zeolites that have not yet been utilized maximally. On the other hand, fishpond farmers have a problem regarding the presence of ammonium in the fishpond water which will negatively impact to survival of fish, especially small fish. To solve this problem, this research was utilizing natural zeolite to degrade ammonium in the fishpond water. This research aimed to test mordenite natural zeolite from Bayah as an adsorbent to collaborate some variables impact to reach more maximal adsorption. The variables that were used to be observed were: mordenite natural zeolite from Bayah as an adsorbent which has been activated by 1-7 N H2SO4 and the other was without activation, ammonium concentration of 80-800 ppm, the particle size of adsorbent of 80 and 150 mesh, stirring speed of 600 and 800 rpm, and without stirring by duration adsorption time of 60 minutes. The research results showed that mordenite natural zeolite after activated was able to adsorb of 100% ammonium, while for the mordenite natural zeolite from Bayah without stirring was of 80%, by the same absorption time. These results will give significant benefits for fishpond farmers to increase their productivity because of the increase in fish survival.Keywords: adsorption, adsorbent, zeolite, amoniumABSTRAKKandungan zeolit alam di Indonesia cukup melimpah dan belum termanfaatkan secara maksimal. Pada sisi lain petani tambak dihadapkan pada masalah terdapatnya kandungan amonium di dalam air tambak, yang akan berdampak negatif bagi keberlangsungan hidup ikan, terutama ikan yang masih kecil. Penelitian ini mencoba memanfaatkan zeolit alam guna mendegradasi kandungan amonium dalam air tambak. Tujuan penelitian ini adalah melakukan pengujian terhadap zeolit alam mordenit dari Bayah sebagai adsorben, baik dilakukan dengan pengadukan maupun tanpa pengadukan, serta mengkolaborasi beberapa variabel yang berpengaruh agar hasil adsorpsi lebih maksimal. Observasi dilakukan dengan zeolit alam mordenit dari Bayah yang telah diaktivasi dengan 1-7 N H2SO4 maupun tanpa aktivasi, rentang konsentrasi larutan amonium 80-800 ppm, ukuran partikel adsorben 80 dan 150 mesh, kecepatan pengadukan 600 dan 800 rpm, dan tanpa pengadukan serta lamanya waktu penyerapan 60 menit. Hasil penelitian menunjukan hasil yang sangat baik, dan secara umum zeolit alam mordenit Bayah teraktivasi telah mampu melakukan adsorpsi amonium sebesar 100%, sedangkan untuk zeolit alam mordenit Bayah tanpa pengadukan sebesar 80% pada waktu adsorpsi yang sama.Kata kunci: adsorpsi, adsorben, zeolit, amonium

Drinking water that is consumed should be clean and healthy. To avoid illness and disruption of bodily functions such as kidney function, liver, brain, teeth, and even mental disorders. Some people in Besole village still use dug well water as a source of drinking water. The geographical state of the town of Besole, Tulungagung district, is a mountainous area of marble containing lime which allows for mineral content, main calcium in the drinking water of residents. This study aims to determine the identification of urine sediments in residents who consume well water in Besole Village, Besuki District, Tulungagung Regency in 2018. This type of research is descriptive non-analytic, by determining the percentage of urine sediments that consume well water through an examination at the Pathology Laboratory STIKes Hutama Abdi Husada Tulungagung. The number of samples is 30 people, with simple random sampling technique. Based on the research conducted found the results of abnormal urine sediment percentage, ie, 6.7% leukocytes, 3.3% erythrocytes, 16.7% epithelium, 30% calcium oxalate and 3.3% bacteria. Water containing lime should be boiled, precipitated and filtered before consumption.

Clean water is one of the human's main needs. Dug well water in Tombang, used for various needs. However, the dug well water has been polluted by E. Coli bacteria which is suspected to be due to the disposal of rubbish and waste carelessly and also the distance of latrines and dug wells that are very close together. Therefore it is important to do water purification using agricultural waste that is not utilized. The analysis showed that the purification of dug well water in Tombang with rice husk charcoal had reduced E. Coli bacteria by 55.6% with MPN pattern 1-0-3 so that the MPN value was 11/100 mL of sample.
