Abstract

ABSTRAK Usaha untuk mendapatkan sarana kontrasepsi pria sebenarnya telah banyak dilakukan dengan memanfaatkan bahan alami yang berasal dari tanaman. Salah satunya adalah tanaman famili Leguminoceae yang mengandung senyawa genistein. Genistein sebagai salah satu senyawa derivat isoflavon mempuyai struktur kimia mirip dengan 17β-estradiol yang bersifat seperti hormon steroid estrogen, yang mampu menyebabkan kerusakan pada sistem reproduksi jantan sebagai salah satu indikator digunakannya genistein sebagai senyawa antifertilitas. Penelitian ini bertujuan untuk mengetahui pengaruh genistein terhadap sistem reproduksi mencit jantan (Mus musculus). Penelitian ini menggunakan pendekatan kuantitatif eksperimental, yang rancangannya mengikuti Rancangan Acak Kelompok. Variabel bebas adalah dosis genistein 0 mg/g, 0,0035 mg/g, 0,0042 mg/g, dan 0,0049 mg/g. Variabel terikatnya adalah sel-sel germinal dalam tubulus seminiferus testis, morfologi spermatozoa, viabilitas spermatozoa, dan kadar hormon testosteron. Data sel-sel germinal dalam tubulus seminiferus testis kadar hormon testosteron dianalisis menggunakan Analisis Varians Satu Jalan (One Way ANOVA) dengan tingkat signifikansi 5%. Selanjutnya dilakukan uji Post Hoc dengan Least Significant Difference (LSD) 5%. Data morfologi dan viabilitas spermatozoa dinyatakan dalam prosentase. Hasil penelitian menunjukkan bahwa ada pengaruh genistein pada sistem reproduksi mencit jantan (Mus musculus). Genistein yang diberikan dengan dosis 0,0035 mg/g; 0,0042 mg/g; dan 0,0049 mg/g berpengaruh terhadap jumlah sel germinal, morfologi dan viabilitas spermatozoa. Kadar hormon testosteron berbeda nyata pada dosis 0,0049 mg/g. Kata kunci : genistein, sistem reproduksi jantan

Abstract

In Indonesia, local buffalo (Bubalus bubalis) is one type of germplasm that a major contribution in the national meat supply of animal protein. However, this germplasm will be reduced of its number.  If this condition continues we will loss the germplasm . One effort to this is conservatuin based on  a molecular marker mikrosatellite . Selected marker locus are HEL09 , INRA23 and ISLTS05 . Sampling area of it research in East Java and West Nusa Tenggara . The results showed that in both are and all loci is polymorphic, allele frequencies ranging from 0.125 to 0.875 and heterozygosity values in the range 35-65 % . These results illustrate that the two populations have genetic diversity that is still quite varied genotype . Key Words: alele frequency, heterozigosity, local buffalo, microsatellite

Abstract

This study was conducted to describe students’ perceptions about the genetic course, laboratory experiment, laboratory facilities, and also students’expectations about the development of the virtual laboratory as an alternative experiment in Genetics Courses. A descriptive quantitative method was used in this study. The participants involved were 49 students enrolling in a genetics course at a public university in Banten, Indonesia. Data were collected through a set of questionnaires. To analyze the data,we employed a descriptive quantitative approach in the form of a percentage. The results showed that the genetic course was considered difficult by the students. The reason is that the material is abstract, and the source of learning is difficult to understand. The most commonly used learning media in the lecture is Power Point.Learning strategies are oftenused,i.e.,the discussions and laboratory work in the laboratory. Students need interesting, communicative, and interactive learning media. The student response is enthusiastic about virtual laboratory development. The expected virtual laboratory criteria are can be used offline, looks interesting, easy to operate, and containsaudio-visual.
