Abstract

Menstruation occurs due to an increase in PGF2 and PGE2 levels, where these prostaglandins can cause contractility in the uterus, causing menstrual pain or what is called primary dysmenorrhea. Primary dysmenorrhea can be treated with pharmacological and non-pharmacological therapies. One of the non-pharmacological therapies to reduce primary dysmenorrhea pain is by giving chocolate drinks (Theobroma cacao) containing magnesium, theobromine and flavonoids that can reduce primary dysmenorrhea pain. The purpose of this study was to determine the effect of giving chocolate drinks on reducing the primary dysmenorrhea pain scale in Bakti Ibu 2 Palembang junior high school students. This research design uses Pre Experimental quantitative research (one group pre test post test). The sampling method in the study used was Non Probability Sampling with Purposive Sampling technique.  The number of respondents was 22 including drop out. The instrument used was a pain scale observation sheet using the Numeric Rating Scale (NRS). The p-value is 0.000 (<0.05) which means that there is an effect of giving chocolate drinks on reducing the pain scale of primary dysmenorrhea in female students of SMP Bakti Ibu 2 Palembang. From this study it can be concluded that there is an effect of giving chocolate drinks (Theobroma cacao) on reducing the pain scale of primary dysmenorrhea in adolescents.

Abstract

Automatic Identification System (AIS) is a ship transponder that uses MMSI data, speed, position, destination, ship type, and size to locate, track, and monitor ships. Only Vessel Traffic Services (VTS) and a few other agencies can be supervised presently. This is one of the issues that must be resolved. To resolve this issue, hardware that can receive AIS signals at 161.975 MHz and 162.025 MHz and convert them into information signals is required. RTL-SDR is hardware capable of receiving signals in the frequency range of 25-1700 MHz. Its antenna is used to achieve maximum signal reception by establishing a direct line of sight to the AIS data source. Yagi antennas can only receive signals from a single direction, the front. Low Noise Amplifier (LNA) is also used in order to optimize the signal received by the antenna. The signal can be processed and decoded using SDR-Sharp and AISMon to provide data that can be plotted on OpenCPN. The performance of the AIS data decoding process is controlled by the strength and weakness of the signal that the RTL-SDR receiver can receive. Therefore, the antenna and receiver must be placed in a clear line of sight (LOS) with the ship's AIS transponder emitting source. It is envisaged that this monitoring system would make it easier to monitor ships in real-time
