Pengaruh Spiritualitas Di Tempat Kerja Terhadap Komitmen Kerja Di Maha Vihara Maitreya, Medan

The background of this research is the author's interest in knowing the effect of spirituality in the workplace on work commitment at Maha Vihara Maitreya, Medan.  The purpose of this study was to determine the effect of spirituality in the workplace on employee work commitment.  This research uses associative quantitative method.  This research is supported by the distribution of questionnaires to respondents.  The sample of this research is Maha Vihara Maitreya employees, totaling 60 employees.  The sampling technique used is a saturated sampling technique.  The results of the normality test for spirituality in the workplace are 0.072 and work commitment is 0.064 where the value is greater than the standard significant = 0.05, so it can be concluded that the data tested are normally distributed.  The results of the linearity test showed that between spirituality at work and work commitment had a linear relationship with a significance of 0.000.  The results of the correlation between spirituality at work with a strong work commitment with the results of 0.764.  The results of the determination coefficient test that the spirituality variable at work affects the work commitment variable by 58.4% while 41.6% is influenced by other factors.  The result of simple linear regression is Y = (-14,584) + 1,234 X, which means that every increase or increase of 1 unit of spirituality will increase work commitment by 1,234 times.  The results of hypothesis testing the calculated T value of 8.95 and obtained the T table value of 2.001.  Where T count > T table (8.95 > 2.001), then Ho is rejected. Ha is accepted, which means that spirituality at work affects work commitment at Maha Vihara Maitreya, Medan.  Thus it can be concluded that "Spirituality in the Workplace has an effect on Work Commitment at Maha Vihara Maitreya"

Hand Parameters and Walking Stick Design: A Case Study among Elderly Malaysian

According to the World Bank, in 2015, the elderly population reaches 8.5% of the world's population. This number grows at 0.13% per annum. In Malaysia, the growth reaches 0.2% of this population annually. Assistive tools such as a walking stick to support the elderly people have become necessary. However, much uncertainty still exists about the relation between the walking stick design and the Malaysian elderly. The objectives of the study were to measure hand dimension and hand grip strength of Malaysian elderly and to relate the hand dimension with the walking sticks being used. There were 50 Malaysian elderly participated in this study and three designs of walking stick available in the market were tested. The first design (handle A) was round and padded, the second design (handle B) was rectangular curve and the third design (Handle C) was round curve. Statistical analysis between hand size and hand surface area shows a linear relationship with R2 = 54% and significant with p-value < 0.05. As for the relationship between the contact area of stick handle and hand size, a linear relationship was found with R2 = 53.3% for handle A, R2 = 46.5% for handle B, and R2 = 36.6% for handle C. This study concluded that the walking stick with high contact area provides better grip and comfort

Biodehalogenation of low concentrations of 1,3-dichloropropanol by mono- and mixed cultures of bacteria

The degradation of low concentrations of 1,3-dichloro-2-propanol (1,3-DCP) and related halohydrins by whole cells and cell-free extracts of soil bacteria has been investigated. Three bacteria (strains A1, A2, A4). isolated from the same soil sample, were distinguished on the basis of cell morphology, growth kinetics and haloalcohol dehalogenase profiles. Strain A1, probably an Agrobacterium sp., dehalogenated 1,3-DCP with the highest specific activity (0.33 U mg protein(-1)) and also had the highest affinity for 1,3-DCP (K-m, 0.1 mM). Non-growing cells of this bacterium dehalogenated low concentrations of 1,3-DCP with a first-order rate constant (k(1)) of 1.13 h(-1). The presence of a non-dehalogenating bacterium, strain G1 (tentatively identified as Pseudomonas mesophilius), did not enhance the dehalogenation rate of low 1,3-DCP concentrations. However, the mixed-species consortium of strains A1 and G1 had greater stability than the mono-species culture at DCP concentrations above 1.0 gl(-1)

Effect of high pressure processing on the conversion of dihydroxyacetone to methylglyoxal in New Zealand mānuka (Leptospermum scoparium) honey and models thereof

The effect of high pressure processing (HPP) on the conversion of dihydroxyacetone (DHA) to methylglyoxal (MGO) was examined in New Zealand mānuka honey and models thereof. The objective was to confirm that previously reported increases of MGO with HPP treatment originated from conversion of DHA. RP-HPLC was used to quantify DHA, MGO and hydroxymethylfurfural (HMF) after derivatisation with O-(2,3,4,5,6-pentafluorobenzyl)hydroxylamine hydrochloride (PFBHA) or (in the case of MGO) separately with o-phenylenediamine (OPD). Fresh and stored mānuka honey, clover honey with DHA added and artificial 26 honey with DHA added were subjected to nine different pressures and holding times and compared to untreated samples. There was no consistent trend of decrease in DHA or increase in MGO for any of the samples with any treatment. Samples showed random change generally within 5–10% of an untreated sample for MGO, DHA and HMF. HPP does not accelerate the conversion of DHA to MGO in honey

Degradation of millimolar concentration of the herbicide dalapon (2,2-Dichloropropionic Acid) by rhizobium Sp isolated from soil

The herbicide Dalapon is widely used in agricultural areas and is persistent in ground water. A Rhizobium sp. was able to grow at 0.2 mM 2,2-dichloropropionic acid (2,2DCP), which was 100-fold lower than the concentration of the substrate routinely used. Apparently, no new dehalogenases are required to allow growth on this low concentration of 2,2DCP as judged by electrophoretic mobility of dehalogenase proteins in native-PAGE analysis and protein separation by anion-exchange column chromatography. The kinetic analysis suggested that the known dehalogenases were able to act efficiently on low concentrations of haloalkanoic acids. The amount of each dehalogenase, from cells grown on low substrate concentration was different compared to that seen at 20 mM 2,2DCP due to complex regulatory controls, which respond to the growth environment
