Neuro-Protection and Neuro-Therapy Effects of Acalypha Indica Linn. Water Extract Ex Vivo on Musculus Gastrocnemius Frog

The studies of neuro-protection and neuro-therapy effects of Acalypha indica Linn. water extract ex vivo on Musculus gastrocnemius frog have already done at three Departments in Faculty of Medicine, University of Indonesia. The experimental studies were done on 2 groups of frog for neuro-protection and neuro-therapy effects. Each group of frog was divided into 7 subgroups of application, 4 samples each. There were 5 subgroups of doses: 5; 10; 15; 20; 25 mg and 2 subgroups as control. Pancuronium bromide 0.2%, 4 mg, was used for a positive control as muscle relaxant. Neuro-protection study was done as follow: ringer – extract – pancuronium bromide, and neuro-therapy study was ringer – pancuronium bromide – extract, respectively. The parameters measured in these studies were the electrical activities such as amount and duration (second) of re-polarization; depolarization, resting potential, and the height of spike after electrical stimulation at 5 mV. Neuro-protection effect of extract was determined by the ability of muscle to show the electrical response after incubating with pancuronium bromide for 10 minutes, and after incubating with extract for 10 minutes for neuro-therapy effect. In the dose of 15 mg and 20 mg/mL of A. indica Linn. extract showed better activities than the dose of 25 mg of extract, both as neuro-protection and neuro-therapy effects, but statistically its have not a significant difference. This study should be followed by an in vivo experiment on frog and it would be done in pharmacokinetic and pharmacodynamic studies on other animal models

Pengembangan Probe Sensor Kelembaban Serat Optik Dengan Cladding Gelatin

Development of Fiber-Optic Humidity Sensor Probe with Gelatin Cladding. Humidity sensor based on optical fiberwith gelatin cladding has been developed. In this humidity sensor probe, the origin cladding of optical fiber is replacedby gelatin coating as humidity sensitive cladding. Testing of the optical fiber sensor probe was conducted by measuringof light intensity transmitted on the optical fiber probe for each variation of different humidity treatments. Response ofthe optical fiber sensor probe measured from 42%RH to 99%RH, the results show an optical transmission curve variedwith relative humidity (RH). Optical transmission in the optical fiber probe increase with RH value at a specificwavelength range, that is from green to red spectrum bands (500 nm - 700 nm), where a significant variation from 600nm to 650 nm in yellow to red spectrum bands. Wavelength where is a maximum intensity of optical transmissionoccurs at 610 nm. Therefore, the optical fiber humidity sensor probe could response humidity form 42%RH to 99%RHwith the best response in humidity range of 60%RH to 72%RH that is have a good linearity and sensitivity

Argumen Pendidikan Seksual Dalam Al-Qur’an (Upaya Penanggulangan Transeksual Pada Anak)

This research aims to Argumens of the Qur'an in the context of sexual education as a solution to prevent the phenomenon of transsexuality in children. The conclusion of this research asserts that Quranic-based sexual education Argumens are not only preventive measures but also effective instruments in combating the negative impacts on children's development and have high relevance in providing protection against the adverse effects of transsexuality on children, exploring efforts to counter transsexuality in children through Quranic-based sexual education. The research conclusion is obtained through critical analysis of the phenomenon of transsexuality from the historical perspectives of religion, psychology, and law. This research is then followed up with a thematic interpretation approach based on Quranic references concerning Argumens of sexual education and transsexuality in children. The methods used in this research are qualitative research with the maudhȗ’î interpretation method and historical-critical-contextual methods. Meanwhile, the approach used is a qualitative method based on literature research, Quranic verses, research publication, journals, conference or seminar proceedings, interviews, and article

PENGARUH KELEMBABAN TERHADAP SIFAT OPTIK FILM GELATIN

Humidity Dependence of Optical Properties of Gelatin Films. Humidity dependence of optical properties of gelatin films prepared by casting technique has been investigated. Gelatin films was investigated its optical properties to varied humidity condition. Optical responses investigated are optical transmission and absorption at visible light spectrum measured utilizing a UV-Vis (Ultraviolet – Visible) spectrophotometer. The results of optical transmittance and absorbance obtained shows an optical response of gelatin films in widely visible light spectrum within range 530 – 680 nm, with most clearly response in a spectrum band in 580 – 650 nm. Different humidity treatment cause a significantly change of optical characteristics, that is the transmittance and absorbance change in to humidity. Transmittance of gelatin films increase with increasing humidity in a range 580 – 650 nm, in contrast with absorbance that is decrease with increasing humidity. Plot of transmission and absorption intensity with varied humidity from 37%RH to 99%RH at 610 nm exhibited a good linearity. Two samples showed same characteristic
