Abstract

Water is one of the most basic needs of all living things, including humans. Water is essential for life because it serves as a barometer for the quality of human life, specifically health. Drinking water is safe for human consumption if it meets the physical, microbiological, chemical, and radioactive requirements specified in the mandatory and additional parameters. In microbiology, the mandatory parameter for drinking water quality is a total of 0 coliform bacteria per 100 ml. The purpose of this study is to quantify the content of coliform bacteria in drinking water at refill drinking water depots in Tahoa Village, Kolaka Regency, that meet or do not meet the requirements outlined in Permenkes No. 492 of 2010. Six refill drinking water depots in Tahoa Village, Kolaka Regency, were used as samples. The method used in this descriptive quantitative research is the most probable number (MPN), which consists of a prediction test and a confirmation test. The results revealed that coliform bacteria were present in drinking water samples A, B, C, D, E, and F, with MPN index values of 240/100 ml, 240/100 ml, and 96/100 ml, respectively. Based on the results of 38/100 ml and 240/100 ml, it can be concluded that the drinking water at the refill drinking water depot in Tahoa Village, Kolaka Regency, does not meet the requirements of Permenkes No. 492 of 2010.

Abstract

This study aims to determine the effect of tofu liquid waste on the growth of mustard greens (Brassica juncea L.). The method used in this study was a Randomized Block Design (RAK) which consisted of 5 treatment levels and 3 replications to obtain 15 experimental polybags. The results of the ANOVA test for the group showed that the height growth of the mustard greens did not have a significant effect, namely FCount (0.52) FTabel (4.46) and for the treatment did not have a significant effect, namely FHitung (0.27) FTabel (4,46), It is suspected that excess nitrogen will produce young shoots that are soft/weak and vegetative, acidify soil reactions, lower soil pH, and be detrimental to plants because it will bind other nutrients so that it will be difficult for plants to absorb them and fertilization will become less effective and inefficient. The results of the ANOVA test on the number of leaves showed that the treatment of liquid organic fertilizer from tofu liquid waste for groups had a significant effect, namely FHitung (5.39) FTabel (4.46), it was suspected that the amount of nutrients absorbed by plants had an effect on the process of leaf formation because the process of forming new cells is very closely related to the availability of nutrients needed by plants. the results of the ANOVA test on the fresh weight of mustard greens showed that the treatment of liquid organic fertilizer from tofu liquid waste for the group had a significant effect, namely (7,69) FTabel (4,46), as well as treatment had a significant effect (22,83) FTabel (4,46), It is suspected that fertilizer is absorbed optimally so that it can support plant metabolic processes and have a good effect on the growth of fresh weight in mustard greens.
