Abstract

Clean water is a serious problem in Indonesia, the availability of clean water has shrunk drastically due to deteriorating environment and pollution. Drinking water that meets safety standards is increasingly scarce. More than 100 million people need safe water sources. Filter media is able to remove chemicals in water such as turbid, odor, oily, yellowish, rusty and muddy making it unfit for consumption. In addition, the purpose of the clarification results must also be considered whether to drink household needs or other needs. This study uses Lauryl Tryptose Broth (LTB) media and petrifilm media. Petrifilm results show that it is very easy to count the bacteria Colifrom and Escerichia coli using petrifilm media. From the analysis of calculations using the Paired Samples T-Test on the sample before filtering and after filtering it was obtained the Tcount value of 2.28 with a P value 0.015 which showed very successful or significant results between the samples before and after the filter. In this analysis have normally distributed data with a significant value of P = 0.015 (<0.05). In this case the Paired Samples T-Test was tested for normality (Shapiro-Wilk) and the results were obtained in the form of a P value of <.001 which would indicate that the data was normally distributed, indicated by a P value <0.05. The filter on this filter is very useful for filtering on Escerichia coli bacteria because this filter removes the bacteria, but Colifrom bacteria can still escape the use of the filter, because it depends on environmental conditions. Colifrom and Escerichia coli bacteria occur is seen from the relationship between sources of pollution such as, for example, such as septic tanks, distance of wells with waste, trash, and livestock pollution. The quality of drinking water is very close to the presence of Colifrom and Escerichia coli bacteria which are likely to have pathogenic bacteria that are harmful to health in the quality of well water. Water samples to be observed using well water using 2 treatments as many as 12 repetitions. Thus the total sample obtained as many as 24 water samples will be observed. While the test making of Lauryl Triptose Broth medium was observed by incubating 48 hours at 35oC + gas. Before making the test tube medium must be sterilized first. Subsequent tests were observed with a petrifilm medium to determine the presence or absence of Colifrom and Escherichia coli bacteria by looking at the color of the battery being sought. Keywords: Drinking Water, Coliform Bacteria and Escherichia coli

Abstract

Permasalahan rutin yang kerap dialami peternak di Desa Tlekung, Kec. Junrejo, Kota Batu adalah sulitnya memenuhi kebutuhan pakan hijauan disaat musim kemarau. Di satu sisi, Desa Tlekung berdampingan dengan lereng Gunung Panderman, yang didalamnya terdapat hutan dengan potensi hijauan sebesar 141.636 ton per tahunnya. Lahan hutan sanggup memasok kebutuhan pakan hijauan disaat musim penghujan, namun hijauan menjadi kering dan langka pada musim kemarau. Akibatnya, peternak mengupayakan pemenuhan kebutuhan pakan pada musim kemarau melalui penggunaan jerami padi. Walaupun demikian, cadangan jerami hasi penanaman di lahan sawah di Desa Tlekung tidak mencukupi untuk memenuhi kebutuhan pakan. Usaha dalam mengatasi kekurangan pakan di musim kemarau dilakukan dengan membeli jerami padi dari luar kecamatan. Upaya ini bukanlah solusi yang tepat guna dalam mengatasi kekurangan hijauan, karena nilai nutrisi yang terkandung dalam jerami padi tidak dapat mencukupi kebutuhan hidup sapi dan domba. Tujuan yang ingin dicapai dalam program pengabdian ini adalah untuk mengenalkan, meningkatkan kesadaran dan memotivasi peternak agar mampu serta berkeinginan untuk menerapkan teknologi ensilase, guna menghasilkan silase sebagai cadangan pakan hijauan disaat musim kemarau. Berdasarkan hasil tahapan evaluasi yang telah dilakukan, tingkat keberhasilan dapat melebihi target kriteria keberhasilan yang telah dilakukan. Secara umum, peserta menyatakan penyelenggaraan pelatihan adalah hal yang penting dan dibutuhkan, dimana peserta menyatakan memahami materi yang diberikan, mampu mempraktekkan pembuatan silase, serta sebagian peserta akan mengimplementasi pembuatan silase. Dengan demikian, kegiatan pendampingan ini dapat dikatakan berhasil, karena mampu meningkatkan pengetahuan dan kemampuan peserta dalam mengikuti kegiatan pengabdian.
