<![CDATA[Domestic wastewater will cause environmental problems, if there is no treatment either communally or household scale or in other words, the people directly dispose of their waste into water bodies. There are several environmentally friendly and fairly inexpensive waste treatment systems, namely the biofilter system. The processing of the wastewater with a biofilter system in several studies resulted in very good reduction of some parameters. This research does not only use biofilter, because it is possible there are still residual inorganic compounds such as nitrate and phosphate left over from processing biofilter systems. So that a tertiary treatment is still needed using a hydroponic system. The results of this study, namely the tertiary treatment system with hydroponics can reduce the residual anoganic compounds of phosphate, such as the outlets of kangkung (76.13%), spinach (44.9%) and lettuce (45.95%), while nitrates did not decrease. The parameters of TDS, TSS, COD and BOD were reduced with the efficiency removal of 15.15-19.60%, 51.20-88.52%, 49.00-63,27% and 30.49-58.68% respectively.]]>

<![CDATA[This The study aims to determine the difference in workload of operator officers in terms of morning, afternoon and night work shifts between COCO’s (Corcoated Owned Corporated Operated). and DODO’s (Dealer Owned Operated Dealers) Gas Stations that operate 24 hours in Yogyakarta Special Region. There are differences between the morning, afternoon and night shifts complained of by the operator, namely that the afternoon shift tends to be more crowded than the other two shifts so that operators feel more tired while working in the afternoon shift. There are differences between the two types of gas stations, namely the ownership system, physical facilities, and management management systems. This study was conducted to analyze the workload both physical and mental in each shift and then evaluate the current shift work system. The measurement of physical workload was carried out objectively by measuring the operator's heart rate to be converted into oxygen consumption and Heart Rate Range (HRR), the results of these measurements were then analyzed statistically using the ANOVA test and the post-hoc Least Significance Different (LSD) test. ) Mental workloads were measured using subjective methods with the NASA-TLX questionnaire. The conclusion obtained is that there are differences in the physical workload of operators in each shift at COCO and DODO gas stations. The operator's oxygen consumption value in each shift is classified as mild to moderate, while the HRR value is still below the recommended limits or can be said to be safe. The mental workload of operators at COCO and DODO gas stations tends to be high to very high categories and indicators of physical needs are indicators.]]>

<![CDATA[Agricultural by-products such as corn silk and kaffir limepeels have not been utilized well. Since every part of a plant contains phenolicscompounds as a result of their secondary metabolism, it is possible that these two wastes can be used as a source of natural antioxidants. Therefore in this study, we investigated the phenolic content in corn silk and citrus peel and assess the ability of the extracts to reduce the conversion of starch to sugar in antidiabetic assessment. Research procedures include raw materialpreparation, extraction, activity assessment and loading the extract into the nanomaterialpores. The results showed that corn silk and kaffir lime peels have different total phenolic contents. Specifically for corn silk, it can be seen clearly that the plant varietycontribute to the amount of total phenolic content. Corn silk from P11 variety has the largest phenolic content up to 1.58 mg GAE/g. Therefore this materialexhibited the highest antioxidant activity against DPPH free radicals, but it has a relatively low for antidiabetic activity. For citrus, this study showed that peels of lemon, lime and kaffir lime exhibited different content of phenolicswith kaffir lime peels extract had the highest phenolics, up to 23.36 mg GAE/g, while the extract of lemon and lime peels were 7.94 and 9.71 mg GAE/g, respectively. In addition, extract of kaffir lime peels has the highest phenolics content compared to other parts such as leaves and juice. The use of different solvents provides different antidiabetic activity. The loading of kaffir lime peels extract into nanomaterial pores was successful, promising future application in the field of drug delivery. However, other studies are still required to improve the effectiveness of diabetes therapy using natural products.]]>

<![CDATA[Application of block system can give positive and negative impact to the students. Evaluation of the implementation of the block system needs to be done to determine the impact of the system applied to the students. Similarly, the impact of the implementation of the block system in Departement of Nursing FiKes UKMC which has started running from 2013 and has never been evaluated. The stress level in this study was measured using the scale of Depression Anxiety and Stress Scale 42 (DASS 42). The measurement scale of DASS 42 contains 42 statements relating to the level of depression, anxiety and stress of a person. The stress statement contained in DASS 42 was modified, so it could illustrate the state of the research subjects. Data collection in the form of questionnaires distributed to students of Departement of Nursing FiKes UKMC as much as 140 respondents. The results of the questionnaire showed that the average respondent's stress level was 12.22, which means having a normal stress level. Statistical analysis using correlation test is used to know the relationship between each variable. The results of the first correlation test relating to gender and stress levels generated correlation coefficient sebasar -0.037 (p = 0.668). Results of the second correlation test between the level of study with stress level generated coefficient correlation sebasar -0.032 (p = 0.710). Results of the third correlation test between GPA with stress level resulted in correlation coefficient of 0.011 (p = 0.893). The last correlation test results between the block system with the stress level with the correlation coefficient value sebasar -0.024 (p = 0.778). From the results of this test obtained all p-values for four hypotheses greater than 0.05, then concluded gender, level of force, and system block is not associated with student stress levels.]]>
