Abstract

The purpose of this study was to examine the effect of adding Nitrifying bacteria in the processfermentation of cow urine, so that the best POC(liquid organic fertilizer) quality was obtained. This research used a completely randomized design (RAL), with five different treatments and three replications. The treatments were carried out using one factor MN1 (2% mollase and Nitrifying Bacteri1%), MN2 (2% mollase and Nitrifying Bacteri2%), MN3 (2% mollase and Nitrifying Bacteri 3%), MN4 (2% mollase and Nitrifying Bacteri 4%), MN5 (mollase 2% and Nitrifying Bacteri 5%) and put into cow urine as much as 5 liters. This fermentation was carried out for 21days, the observed variables were Electrical Conductivity (EC), Degree of Acidity (pH), Total Dissolved Solids (TDS), temperature, microbial population, C-Organic, and N-total. In the fermentation process for 21 days, the N-Total value was not significantly different for each sample. While the C-Organic on day 21 of the MN5 sample had the lowest value, namely 0.52%. While the C-Organic on day 21 of the MN5 sample had the lowest value, namely 0.52%. For the results of the bacterial population samples MN4 and MN5 on day 15 experienced a decrease in population development. During the 21-day fermentation process the best results occurred in MN2 samples (2% molasses and 2% nitrifying bacteria), when viewed from the final values of TDS, EC and C-Organic. This research can increase N-total and the development of bacteria which is quite good, but this result is still far from the standard set by the Decree of the Minister of Agriculture of the Republic of Indonesia No: 261/KPTS/SR.310/M/4/2019.

Abstract

Fatigue and a high workload cause a decrease in energy in humans so that work cannot be completed properly. The number of calories that do not meet the body's metabolic needswill cause a decrease in a person's physical capacity. One solution to keep the number of calories available to meet the basic needs of metabolism is to schedule meals and snacks at work. One of the scheduling is a snack at 10.00 am with a calorie contentof 10% of daily calorie needs. This study aims to determine whether the provision of snacks can reduce fatigue and workload of leek farmers. The snacks that will be given in this study are one bottle of 600 ml mineral water with 0 kcal, one 110 kcal kue getas, one100 kcal martabak mini, and one 118 kcal kue lapis. This type of research uses descriptive quantitative methods. The units used in this study found 30 units using the purposive sampling technique. Subjective fatigue data was obtained by filling out the Fatigue Severity Scale questionnaire to determine the level of fatigue experienced by the unit while the workload data was obtained by calculating the pulse (before work and completion) of work and filling out the NASA-TLX workload questionnaire. Inthis study used data analysis with validity test, reliability test, normality test Kolmogorov-Smirnov, and statistical test Paired Sample T-Test. The results showthat there is a decrease in fatigue by 24% and a decrease in workload by 7% by giving snacksto leek farmers, but there is no significant difference between the number of pulses that are not given snacks and the number of pulses given the snack. So, from the results it says that leek farmers in Bukit Catu are workers who do not have a high workload but farmers experience high fatigue.

Abstract

The usage of pesticides that do not by following the rules can give a negative impact on human health and the environment. This study aims to determine a relationship between usage of Personal Protective Equipment (PPE) with farmer complaints due to pesticides in Subak Sri Gumana, Rejasa Village, Tabanan Regency. This study used samples amount 30 people (16%) from 189 farmers in Subak Sri Gumana. The instrument used the questionnaire Likert scale which provides choices for respondents to answer. Based on the result of chi-square test, the p-value is 0.002 (p <0.05), so there was a relationship between usage of Personal Protective Equipment (PPE) with farmer complaints due to pesticides in Subak Sri Gumana, Rejasa Village, Tabanan Regency. The conclusion is found a relationship between the usage of personal protective equipment (PPE) with farmers complaints due to pesticides in Subak Sri Gumana, Rejasa Village, Tabanan Regency. These complaints arise because farmers haven’t used Personal Protective Equipment (PPE) and ignore the dangers of using pesticides.
