Abstract

Humans as workers play an important role in producing tofu products in quality and quantity. Making production room facilities needs good arrangement so that workers do not feel risks or complaints while carrying out activities. The purpose of this research was to help the level of complaints felt by workers in the production of tofu using the Nordic Body Map (NBM) method. The method used in this study was a descriptive method by exploring problems using a questionnaire to get 4 categories of complaint levels, namely not sick, slightly sick, sick, and very sick. There were 8 subjects studied consisting of 4 male workers and 4 female workers with a minimum working period of 5 years. The results and discussion show that the work station for making tofu needs rearrangement to facilitate moving from one station to the next work station, and found complaints felt by workers with a total score in the range of 63% -88% (high risk) in the upper neck , left and right shoulder, right wrist, right upper arm, waist, left and right ankle and left and right leg so that a comprehensive action is needed to be corrected immediately

Abstract

Cayenne pepper plants are one of the plants that are susceptible to excess and lack of water during their growth period. Lack of water can cause chili seeds to not grow optimally, so chili plant nurseries need ideal media to be able to provide optimal water. This research aims to determine the growth and duration of the permanent wilting point in the growth of chili plant seeds based on differences in planting media in the form of magot compost, soil containing pumice and paddy soil under conditions without watering. The treatment in this research used three different planting media, namely compost, pumice, and paddy soil media. Providing water to chili plants by watering 3 times a day and without watering. The research method uses experimental methods with observations in the greenhouse and there are three treatments, namely using magot compost, pumice and soil media. The parameters observed included growth in height, number of leaves, and width of the plant leaves as well as the length of time to the permanent wilting point. The data from the research were analyzed using ANOVA with the help of SPSS. The results of the research showed that the compost media had the best growth with a height of 9 cm, the number of leaves was 6 pieces, and leaf width 2.9 cm, while the permanent wilting point duration of the three media used was found in compost media, which experienced the longest permanent wilting point at the age of 10 days. So it can be concluded that the best planting medium is found in maggot compost media with the highest growth and longest wilting point.

Abstract

Fossil energy reserves to date are dwindling inversely proportional to the amount of consumption. So to overcome this problem, alternative energy is needed, one of which is biogas which is sourced from organic waste. The biogas production process has so far experienced many obstacles so that the formation of pressure has not been optimal. The aim of the research was to create a model to see the magnitude of the influence of humidity and temperature on the pressure of the biogas produced. The method used is multiple linear regression with the following stages, identifying variables, testing classical assumptions, model building, and model goodness. Based on the results of the analysis, the model Y ̂=17.029-0.042X_1+3.480X_2 is obtained. Simultaneous test results show that simultaneously humidity and temperature have a significant effect because the sig is 0.000<α(0.05). The results of the partial test (T-Test) of each variable also showed significant results on biogas pressure because the sig was 0.000<α(0.05). The coefficient of determination of 0.8180 means that humidity and temperature variables affect the formation of biogas pressure by 81.80% and the rest is influenced by other factors such us pH, C/NRatio, starter, and so on.
