Abstract

Diabetes mellitus is a chronic disease that occurs due to the pancreas not being able to produce enough insulin or when the body cannot effectively use the insulin. The purpose of this study was to study the effectiveness of the provision of red betel leaf boiled water on reducing blood sugar levels of Diabetes Mellitus patients in the Saling Puskesmas District of Four Lawang in 2018. The design of this study was an experimental Quasy using The One Group Pretest - Postest Design, technique data collection using primary and secondary data. The population of this study were all Diabetes Mellitus patients in the Saling Community Health Center in July-August 2018, amounting to 16 people, sampling was done by accidental sampling. The results of the study, from 16 patients with diabetes mellitus there are 9 people (56.2%) with blood sugar levels less than 200 mg / dl. Wilcoxon Sign Rank test results obtained value Z = -3.517 with p = 0.000 0.05 means significant. So the two variables have different medians, there are differences in the GDS levels of Diabetes Mellitus patients before and after administration of red betel leaf decoction water. Conclusion, Red betel leaf decoction water is significantly effective in reducing blood sugar levels in patients with diabetes mellitus. It is expected that Puskesmas staff can increase public knowledge by counseling about red betel leaves as a Non-Pharmacological drug for patients with Diabetes Mellitus who do not experience complications. Keywords: Red Betel Leaf Decoction Water, Diabetes Mellitus, Blood Sugar Levels

Abstract

This study aims to improve student learning outcomes on chemistry subjects by applying the Teams Games Tournament (TGT) learning model for tenth-grade students. The method used is classroom action research that is carried out in three cycles, each cycle consisting of two meetings. Techniques of data collecting use the observation sheet and final testing cycle. Observation sheet was used to determine the activity of students and the test to determine student learning outcomes. Based on research, gained mastery learning outcomes of students increased from 45% before treatment (T0) to 55% in the first cycle (T1), 72.5% in the second cycle (T2) and 87.5% in the third cycle. Average student activity within the group at the first cycle of 53.43%, 57.18% for the second cycle and the third cycle of 64.47%. Average student learning outcomes at the first cycle of 70, 55, 72,125 for the second cycle and the third cycle of 74,6. Cooperative learning strategies are effective when the curricular knowledge taught in the school is drawn from all groups by playing. Based on these results, the researchers suggest to teachers who have the same problem in learning can apply learning model Teams Games Tournament (TGT).

Abstract

Power electronics is a field that studies electronics applications related to electrical equipment that uses large amounts of power, one of the subject that studied is AC to AC converters. AC voltage regulator is a converter where the output frequency is the same as the input frequency of the voltage sources, while the RMS output voltage can be regulated. In this research the number of phases that used are six phases, and two SCRs that used to chopper the AC voltage wave that arranged it in revers for each phase.The control circuit is constructed by using an op-amp which functions as a comparator and several other basic electronic components. the simulation results that using PSIM software for several delay angles including 30o, 60o, 90o, 120o, and 150o produce rms voltage that is relatively the same as the analysis by using mathematically calculations, this difference is because the SCR gate delay angle is still done manually, in general the voltage regulator The six-phase AC in this study can work well.

Abstract

Salafism, a reformist movement that follows a school of Islamic understanding unaffected by Hellenism. Its aim is to maintain the views of the salaf scholars. The author uses the historical method by collecting data through library research sourced from books, articles, and other related information. The results of this study discuss various Salafi schools that emphasize three main characteristics in their teachings, namely placing Islamic law (sharia) above reason, avoiding rationalist interpretations, and upholding the text of the Quran and Hadith. Of course, this is closely related to the influence of thinkers such as Ibn Taymiyyah who was the main thinker, followed by Muhammad bin Abdul Wahab as his successor

Abstract

In general, palm oil processing factories, from fresh fruit bunches to Crude Palm Oil, require three-phase electric motors to drive or rotate it. The problems that often arise when using three-phase electric motors simultaneously in large numbers will result in very large surges in the electric current, which can affect the performance of electronic devices. To overcome this problem, a prototype of a three-phase AC voltage regulator circuit was made by adjusting the SCR triggering delay angle using an analog electronics equipment control that can be used for three-phase motor soft start applications in a palm oil factory. This prototype will be used as a learning tool for the practical for Aceh Polytechnic students for power electronics courses. This system is built with a method where the three-phase source is first lowered using a transformer arranged in a star on the primary and secondary sides, then each voltage is compared to the ground using an IC LM324, which aims to produce pulses wave. This pulse then connected to a triangular wave generator circuit, this triangular wave is then compared with the DC source voltage from the potentiometer, which aims to regulate the SCR triggering angle of SCR via MOC3063 driver, where the load used is resistive and connected in a star. The measurement using an oscilloscope and observing the change of triggering angle for several variations of each phase, the different Vrms voltage between measurements compared to mathematical analysis influenced by several factors, including, the transformer is made of three transformers that not identically, the electronic components used are not in ideal condition, and observations on the oscilloscope are carried out visually using the eye and manually adjusting the potentiometer rotation so that the level of measurement accuracy between one person and another will produce different values.

Abstract

One of the sub-subjects that studied in the power electronics course is the AC to DC converter in the form of a three-phase half-wave controlled rectifier where the output voltage can be controlled by adjusting the SCR gate trigger delay angle, in this research the author design and simulates an SCR triggering circuit for three-phase half-wave controlled rectifier where the components that used among others a three-phase step down transformer where the output functions as a reference signal to determine the starting point (30o) and end point (150o) of the triggering delay angle, also used as a power source for the system, the Op-Amp functions as a comparator for a three-phase rectifier (Vd) with a DC voltage (Vreference), it also functions to compare a triangle wave with a DC voltage to control the delay angle or trigger angle (α) of the SCR. The trigger pulses that given to the SCR1, SCR2, and SCR3 are carried out simultaneously in the same time by using one pulse, the average output voltage resulting from the SCR trigger circuit design in this research is relatively the same as the value obtained using mathematically calculations where the load used in form of resistive
