No full textEvaluation on The Supplementation of Fermented Garlic Extract in Protecting Human Lymphocytes In Vitro From The Negative Impact of Gamma-Rays
No full textGarlic (Allium sativum) contains a wide range of phytocompounds that produce various responses in human body. However the knowledge on the potential of fermented form of garlic in protecting negative impacts of radiation is very limited. In this research in vitro efficacy of fermented garlic in protecting negative impact of gamma ray was studied using cytogenetic test. A set of culture of human lymphocytes was irradiated with 60Co gamma rays at dose of 2 Gy (dose rate of 2 Gy/min) and fermented garlic extract at four working concentrations of 0, 125, 250 and 500 mg/mL were added to these cells and then were incubated at 37oC for 48 hrs. Colcemid was added at 3 hr before harvest to collect metaphase cells and it was done by standard methodology for cytogenetic analysis. The fermented garlic extract significantly (p<0.05) did not exhibited antigenotoxic effect of gamma rays and its effectiveness was same as in control (without extract treatment) group. In contrary all concentration of chemicals (125, 250 and 500 mg/mL) were seemingly tend to induce higher number of dicentric and fragment chromosomes than control under microscopic observation. Mitotic index of the cell that was determined with programmed metaphase finder also did not influenced by garlic addition. It was concluded that aqueous garlic extract did not possesses its efficacy in protecting impact of ionizing radiation

No full textThe nurse is one of the main components in providing health care to the patient , the presence of nurses providing more value than a treatment , so that patients do not just get the health care that are holistic . The purpose of this study is to examine and determine the direct effect of leadership style on performance, to test and determine indirect influence of leadership style on performance through job satisfaction , and to examine and determine the direct effect of job satisfaction on performance.The hypothesis of this study leadership style through job satisfaction of nurses affect the performance , leadership style directly affects the performance of nurses , and job satisfaction directly influence the performance . Respondents for this study as many as 180 people , because the population is already known, the method of data collection using census methods and to answer this hypothesis , a number of analytical tools have been used by the analysis tool that analyzes the path . The author uses the path analysis.From the results of the analysis carried out can be concluded that the first hypothesis that the style of leadership through job satisfaction has positive influence on employee performance is proven, the second hypothesis leadership style direct positive effect on the performance of nurses proved, to the satisfaction of three direct positive effect on the performance of nurse

ANALISIS PERBANDINGAN QUALITY OF SERVICE (QOS) VIDEO CALL FACEBOOK DENGAN VIDEO CALL SKYPE MENGGUNAKAN JARINGAN BERBASIS 4G
No full textThe wider internet users in Indonesiathe number of video calls
is increasing, especially in Facebook video calls and Skype video calls.
This increase is based on very rapid technological developments,
especially PCs, Laptops and Smartpones that use wireless internet
access or wireless. The use of video calls through wireless networks is
different from cable networks because the characteristics of wireless
networks are limited compared to cable networks, and the
characteristics of video call transmission that require different handling
than the transmission of text and data in general. As an initial step to
achieve an optimal effort to improve Internet network services,
measurement results are needed that represent the average value of
Internet network service performance against changes in QOS
parameter values when accessing video call services on 4G networks.
This study applies the method of literature study wherein this
method the author conducts studies from the internet, journals, and the
final project on Quality Of Service. QOS parameters analyzed consist
of Bandwidth, Throughput, Delay, Jitter and Packet loss using
Wireshark and Nettools for the testing phase.
From the results of this study, the differences were not so
significant between each video call service. Although not so significant
Skype video call services have better results than Facebook video call
services. From the results of this study, the two video call services can
be used as a consideration for the user in choosing the use of video calls
according to their individual needs
Organic carbon burial and sources in soils of coastal mudflat and mangrove ecosystems
No full textMangrove organic carbon is primarily stored in soils, which contain more than two-thirds of total mangrove ecosystem carbon stocks. Despite increasing recognition of the critical role of mangrove ecosystems for climate change mitigation, there is limited understanding of soil organic carbon sequestration mechanisms in undisturbed low-latitude mangroves, specifically on organic carbon burial rates and sources. This study assessed soil organic carbon burial rates, sources and stocks across an undisturbed coastal mudflat and mangrove hydrogeomorphological catena (fringe mangrove and interior mangrove) in Bintuni Bay, West Papua Province, Indonesia. 210Pb radionuclide sediment dating, and mixing model of natural stable isotope signatures (δ 13C and δ15N) and C/N ratio were used to estimate organic carbon burial rates and to quantify proportions of allochthonous (i.e., upland terrestrial forest) and autochthonous (i.e., on-site mangrove forest) organic carbon in the top 50 cm of the soil. Burial rates were in the range of 0.21–1.19 Mg C ha−1 yr−1. Compared to the fringe mangroves, organic carbon burial rates in interior mangroves were almost twice as high. Primary productivity of C3 upland forest vegetation and mangroves induced soil organic carbon burial in interior mangroves and this was consistent with the formation of the largest organic carbon stocks (179 ± 82 Mg C ha−1). By contrast, organic carbon stored in the fringe mangrove (68 ± 11 Mg C ha−1) and mudflat (62 ± 10 Mg C ha−1) soils mainly originated from upland forests (allochthonous origin). These findings clearly indicate that carbon sequestered and cycling in mangrove and terrestrial forest ecosystems are closely linked, and at least a part of carbon losses (e.g., erosion) from terrestrial forests is buried in mangrove ecosystems. © 2019 The Author
