<p class="AbstractL-MAG"><span lang="EN-US">SWR Analyzer is an electronic device radio is useful to know the value of VSWR and antenna impedance without the use of radio tranciever. In this final use Direct Digital Synthesizer (DDS) to generatewaveforms analog digitally. DDS signal generation programmable via Arduino nano. The frequency used is aantenna operating frequency dipole 7 MHz which are in the range 6.9 MHz - 7.4 MHz.calibration SWR Analyzer is done by providing a form of pure resistor load with the acquisition of a data error of 4% as compared with the theory. The test results niali VSWR atantenna dipole 7 MHzusing an SWR Analyzer then compared with measuring devices in general, ie VSWR SWR meter. Earned value matching 1: 1 obtained by SWR Analyzer at a frequency of 6.9 MHz, while using the SWR meter lowest VSWR values obtained at 7:04 MHz frequency with a value ofratio matching impedance1:35: 1.

Value Measurement

Performance measurement in manufacturing industry is usually measured with the approach of OEE (Overall Equipment Effectiveness). In the mining industry, backhoe excavator performance can also be measured by OEE value approach. OEE value measurement performed on the excavator in coal mine Embalut Kaltim. In the case study on the company, the performance analysis also compared with the backhoe excavator defined performance targets of the company. OEE Value mine done OEE parameter modification into 3 dimensions: availability, utilization and productivity index. OEE measurement mine OB Removal devoted to the activity, as this activity has a value greater than most activity cost Getting Coal. The measurement results OEE values for the existing conditions is very low. Two of six units which have a low OEE value. The low value of OEE most influential is the utilization value. If compared with OEE value targets, there are five units of backhoe has a value below the target. Efforts are being made to improve OEE values is by the application of TPM: implementing autonomous maintenance, implementation of SMED: change the internal activity into external and doing jobs that could be eliminated or Parallelize and application 5W1H: make your creative ideas by way of brainstorming or explore the idea of problem solving, After implementation of the improvement idea, the value of simulation obtained quite good, an increase compared with OEE value before improvement. Keyword : Availability, Utilization, Productivity Index, TPM, SMED, 5W1H.

In this study, we describe the development of a plug-in type of switchgear that can control bidirectional power flow. This switchgear system can connect distributed generations such as photovoltaic and wind turbine generation, and AC and DC loads. The proposed switchgear system consists of an inverter for connecting distributed generations and DC load, a static transfer switch (STS) that can control and interrupt the bidirectional power flow, and an intelligent electronic device (IED) that can control each facility using a communication system. Since the topology inside the switchgear is composed of DC bus, it can be operated as a plug-in type of system that can be used by simply connecting the converters of various distributed generations to the inverter in the developed switchgear system. In this study, we describe the overall structure of the proposed switchgear system and the operation of the components. In addition, prototypes of each facility are developed and the results of building a small testbed are presented. Finally, we verify the operation of the inverter by performing an experiment on the testbed and show that throughout a test sequence the proposed switchgear system works normally. The contributions of this study are the development of a plug-in type of switchgear for AC/DC and the actual test results presented through prototype development and testbed configuration.

Preeclampsia complicates 4-7% of pregnancies and remains the leading cause of maternal and fetal morbidity and mortality worldwide. Despite improvements in health care over the last decade, preeclampsia remains the second most common cause of maternal mortality in Indonesia. This study aims to determine whether the mean arterial pressure (MAP) is related to the incidence of preeclampsia in pregnant women at the Bontobangun Puskesmas, Bulukumba district for the period 2018 to 2019. This research uses a descriptive-analytic approach with Historical Cohort Studies, namely by looking at the cohort book of the history of blood pressure measurement results for pregnant women at the Bontobangun Public Health Center, Bulukumba Regency for the period 2018 to 2019. Determining the sample using the sampling method taken by purposive sampling. 31 samples of pregnant women who experienced preeclampsia and 31 controls were pregnant women with normal conditions who had certain criteria (matching) with the sample. The results explained that from the paired T-test results, the value of α> 0.037 so that it is said that there is a relationship between mean artery pressure (MAP) and the incidence of preeclampsia in pregnant women at Bontobangun puskesmas for the period 2018-2019.
