Abstract

The participation of men in family planning is still relatively low when compared to the participation of women. One of the traditional medicinal plants used is antifertility hibiscus flowers. This study aims to examine the effect of hibiscus flower extract on the number, motility, morphology and viability of spermatozoa of male rats (Rattus norvegicus). This research is an experimental study using a completely randomized design (CRD). The sample in this study used 25 male Sprague Dawley strains aged 60-70 days with a body weight of 200-210 grams. Duration of treatment for 30 days at a dose of 200 mg / kg, 300 mg / kg, 400 mg / kg. Data is presented in the form of tables and diagrams and narration to interpret the data. The results of this study indicate a decrease in sperm count in the treatment group compared to the control group (p = 0,000), a decrease in sperm motility (p = 0.001), an abnormal morphological increase (p = 0,000), and a decrease in spermatozoa viability between the treatment groups compared to the group control (p = 0,000). It can be concluded that there is a significant difference in the effect of hibiscus flower extract on the number, motility, morphology, viability of spermatozoa.

Abstract

Hibiscus rosa-sinensis Linn. is one of the medicinal plants in Indonesia which is used as male contraception. Hibiscus flowers contain flavonoids which can reduce testosterone. The purpose of this study was to determine the effect of hibiscus flower extract on epididymal weight, cauda epididymal epithelial thickness, prostate weight and seminal vesicle of male rats. This research is an experimental study using a completely randomized design (CRD). The sample in this study used 25 male Sprague Dawley® strains aged 60-70 days with a body weight of 200-210 grams. The treatment dose is 200 mg / kg, 300 mg / kg, 400 mg / kg, 500 mg / kg for 30 days. The data is presented in tabular form and narrative to interpret the data. The results showed a decrease in epididymal weight in the treatment group compared to the control group (p = 0,000), there was also a thick shrinkage of the cauda epididymal epithelium (p = 0.021), a decrease in prostate weight and seminal vesicles between the treatment group versus the control group (p = 0.001). It can be concluded that there is an effect of hibiscus flower extract on the epididymis, prostate and seminal vesicles. The influence is likely due to the chemical content that is in hibiscus flowers that are antifertility.

Abstract

Fading is a phenomenon of decreasing signal strength during transmission, caused by changes in environmental conditions or physical obstacles in the propagation path. Fading can cause interference in signal reception, such as distortion or loss of information, especially in Non-Line of Sight (NLoS) paths, where signals must pass through many paths or obstacles such as buildings, trees, or other objects. To eliminate fading interference, a cooperative communication system is created to reduce the effects of fading in wireless networks. The cooperative communication system works by utilizing other nodes in sending signals to the destination. The relay protocol used in this study is amplify and forward, where the signal to be sent will be amplified and forwarded to the destination by the relay node. A network coding scheme is added to the cooperative communication system to improve network performance. This scheme encodes each piece of information with the XOR technique. The parameters used in measuring the network coding scheme in the cooperative communication system are BER and throughput. Viewed from the BER value, the conventional cooperative communication system has better performance compared to the cooperative communication system with network coding. Cooperative communication system scheme without NC BER value is 0 when the transmit power value is -19 dBm or Gain 32. While for the cooperative communication system scheme with network coding BER value is 0 when transmit power of -9.25 dBm. Throughput system with network coding has increased by 17% compared to the conventional system.

Abstract

Ownership and use of healthy latrines is one of the indicators of the Clean and Healthy Behavior (PHBS) program in the household environment. Based on the results of the PHBS study, nationally the percentage of households using healthy latrines (39%), in urban areas (60%) is much higher than in rural areas (23%). The percentage of households using healthy latrines in West Java Province is slightly above the national average of 39.6%. The use of latrines is an important health problem both in rural areas and in Kertaharja Village. In the development of healthy latrines in Parakan Hamlet, two points were built, namely in the Karang loa block RT 08 Rw 03 and the Gatah block RT 12 RW 05. However, even though the latrines have been built, their utilization is still not optimal. where people still carry out open defecation activities such as in open land. Therefore, KKN UMTAS students carry out counseling activities on clean and healthy living behavior in every household along with Open Defecation Free (ODF) activities, where counseling is given to the people of Kertaharja Village, especially in the Parakan Hamlet area. The purpose of this activity is to improve clean and healthy living behavior (PHBS) in Kertaharja Village, especially in Parakan Hamlet by building healthy latrines after socialization, site surveys, triggering and pre-development, then developing a declaration from the local community about the use of latrines that have been built. . The declaration of Open Defecation Free (ODF) was held on September 7, 2022, which was attended by the community, village officials, students and was attended by the Deputy Regent of Pangandaran and the Camat of Cimerak
