Abstract

This study aimed to determine the effect of giving Infarm POC concentration variations on the growth of green mustard (Brassica juncea L). The research employed a completely randomized design (CRD) or randomized block design with 6 treatments and 5 replications, resulting in a total of 30 experimental units. The data collection method and mechanism used involved implementing a completely randomized design (CRD) with 6 types of treatment and 5 replications, leading to the cultivation of 30 mustard plants with POC concentrations ranging from 2% to 10%. The findings revealed that the application of POC fertilizer to mustard plants resulted in increased plant height, leaf count, and resistance to leaf pests. Notably, the POC concentration of 6% exhibited the most significant improvements in plant height and leaf count. However, to gain a more comprehensive understanding of the effectiveness of this POC, further research is necessary. It is recommended to extend the duration of the study until harvest to assess the weight and quality of the mustard greens, thereby providing more conclusive insights

Abstract

This research aims to examine the effect of the thickness of coconut shell composite board on elasticity, sound absorption, water absorption, and density. The elasticity test was conducted using the tensilon RTF2350 machine at the Faculty of Mechanical Engineering and the sound absorption test was conducted using the sound level meter GM1352 at the Faculty of Science and Mathematics of the State University of Yogyakarta. The thickness of the composite board was varied, and its elasticity was measured using the tensilon RTF2350 machine, the sound absorption measurement was determined using a sound level meter with a sound source from a sound generator with a frequency of 1000Hz and intensity of 20 dB, while the thickness was varied. The elastic modulus decreased with the increase in partition thickness, sound absorption decreased with the increase in partition thickness, and water absorption increased with the increase in partition thickness. Water absorption was determined by submerging the partition into distilled water for 30 seconds and observing the mass before and after immersion into the water.

Abstract

This study aims to determine the effect of silica sand mass in the air purification system on the decrease in Fe concentration. The type of research used is experimental research. The water purification media used in the research were silica sand and gravel. The mass of gravel used in the water purification system is constant, namely 500 grams. The mass of silica sand used varies, namely 200 grams, 400 grams, 600 grams, 800 grams and 1000 grams. The research was carried out through three stages, namely the stages of preparation, implementation, and data collection. The effect of the mass of silica sand in the air purification system on decreasing the concentration of Fe showed positive results. The results of research with a fixed mass of gravel and varying masses of silica sand showed a decrease in Fe concentration after water purification with a value that met environmental health quality standards and water health requirements Fe (iron) content below 1 mg/L or ppm so that the water worth using.

Abstract

This study aims to determine the antibacterial activity of the cinnamon extract in inhibiting the growth of Escherichia coli. The research design was a laboratory experiment consisting of three phases, namely the preparation phase of cinnamon extract using the maceration method using 96% ethanol, the characterization phase consisting of qualitative analysis with phytochemical tests and quantitative analysis with UV-Vis spectrophotometry, and the application phase including antibacterial activity test by disc diffusion method (Kirby-Bauer Test). The concentration series were 20%, 40%, 60%, 80%, and 100%, chloramphenicol as the positive control and methanol as the negative control. The results showed that cinnamon extract positively contained flavonoids with a total content of 1.310 mg QE/g or 0.131%. Cinnamon extract is effective as an antibacterial in the medium category with the optimum concentration to inhibit Escherichia coli is 40% indicated by the diameter of the inhibition zone of 9.55 mm at 12 hours of incubation. Therefore, the cinnamon extract has potential activity against Escherichia coli.
