Abstract

Papaya seeds (Carica papaya L.) was known have antifertility activity. Testosterone hormone and reproduction organs weight are influence antifertility activity. This study was conducted to compare the effect of the methanolic extract, fraction of n-hexane, and fraction of methanol papaya seeds ( dose 100 mg/kg BW ) with testosterone level and reproduction organs weight parameters of male rats. Measurement of testosterone level by ELISA method. The observation found that the three treatment didn’t decrease reproduction organs weight but decrease testosterone level compared to negative control group. Among the three treatments, metyhanolic extract and methanolic fraction decreased testosterone level. Extract and fraction of methanol alleged alkaloid content of which is known to inhibit development and count of spermatogenic cell.   Keywords: papaya seeds, testosterone, alkaloid, organ

Abstract

One of the impacts of reclamation of swamps is poison substances in the water channels, which can cause to pyrite oxidation, sedimentation and accumulation of toxic substances in secondary channels. The reclamation channel unit in Semangat Karya Village has a water pH of ± 3 and has the iron level of 4.95 mg / l. Based on South Kalimantan Provincial Governor Regulation Year 2007, pH grade and iron concentration are over the quality standard, while the water is consumed by the residents for everyday intentions. One of the technologies that are applied to increase the pH and to minimize the concentration of iron (Fe) is constructed wetland with the horizontal sub-surface flow (CW-HSSF).  The objectives of this research were to study the dynamics of pH and Fe in the media acid sulfate soils mixed with organic fertilizer (bokashi) 10% at CW-HSSF  system using  Purun Tikus (Eleocharis dulcis) and Kalakai (Stenochlaena palustris). The conclusion of this research indicated that pH value and absorption of Fe in CW-HSSF using Purun Tikus (Eleocharis dulcis) was better than Kalakai (Stenochlaena palustris).

Abstract

Abstrak: Penelitian pemanfaatan ekstrak daun pepaya (Carica papaya L.) telah dilakukan untuk mengetahui potensinya dalam memberikan efek sedasi pada mencit (Mus musculus L.). Metode yang digunakan adalah metode eksperimen dengan Rancangan Acak Lengkap (RAL) menggunakan analisis keragaman. Penelitian menggunakan 24 mencit jantan yang terdiri dari empat perlakuan dan  enam ulangan. Perlakuan pemberian dosis  ekstrak daun pepaya terdiri dari 0 mg/10 g BB, 2 mg/10 g BB, 4 mg/10 g BB, dan 8 mg/10 g BB. Data waktu ketahanan mencit di atas hot plate dianalisis dengan perhitungan analisis keragaman dan dilanjutkan dengan Uji Beda Nyata Terkecil (BNT). Hasil penelitian yang didapatkan adalah rata-rata waktu mencit bertahan di atas hot plate yang tertinggi terdapat pada dosis 8 mg/10 g BB yaitu 211,67 detik. Analisis keragaman menunjukan bahwa ekstrak etanol daun pepaya berpengaruh sangat nyata terhadap ketahanan mencit terhadap panas di atas hot plate. Uji BNT menunjukan bahwa terdapat dosis ekstrak etanol daun pepaya yang efektif meningkatkan waktu ketahanan mencit di atas hot plate yaitu  pada dosis 8 mg/10 g BB. Hasil penelitian ini dapat dijadikan sebagai informasi bagi Pembelajaran Biologi SMA kelas XI semester II pada kompetensi dasar 3.8 khususnya mengenai Gangguan pada sistem koordinasi   Kata kunci : Carica papaya L., sedasi, Mus musculus L.

Abstract

A study has been conducted on influences of various chitosan concentrationas coating and storage time to Vitamin C concentration of green grape (Vitis vinifera L.) by dipping method. This study aims to de-termine the difference of chitosan concentration to physical characteristics, weight loss and vitamin C concen-tration of green grape. Chitosan coating was conducted on 50 grams of green grape by dipping method at var-ious concentration of chitosan that is 0%, 0,5%, 1%, 1,5% and 2% (w / v), kept on variation of one, four and seven day storage time. Determination of vitamin C concentration of green grape was done by UV-Vis spec-trophotometer measured at 256 nm wavelength with regression equation y = 0,0344 x + 0,101 and r = 0,998. Based on statistical test showed that chitosan concentration of 1% (w / v) with 4 days storage time is the most optimum because the chitosan layer is able to close all green grape pores, so the process of anaerobic and CO2 respiration can be inhibited by chitosan solution.
