Abstract: This study aims to reveal the perceptions and needs of pre-service biology teachers on biotechnology learning and their need for instructional media, especially on the topic of basic molecular biology techniques. This descriptive quantitative study was done purposively on 42 students who have completed the biotechnology lectures in Biology Education Program, Universitas Negeri Malang. The data collection instruments consisted of a biotechnology topic difficulty survey questionnaire and a felt needs questionnaire. The questionnaire response data analyzed using descriptive statistics showed that students perceived the laboratory activity of basic molecular biology techniques as a moderate level. On average, all students performed DNA analysis techniques, and only 55% of all students performed protein analysis techniques. Overall, students have feelings, understanding, and confidence at a moderate level, while they feel they have excellent learning assistance. Even so, students feel they need learning resources in the form of research-based multimedia to support learning on the topic of practicum on molecular biology analysis techniques, especially in protein analysis techniques. Research-based protein analysis techniques multimedia that is suitable for students' university cognitive development are considered to be developed in supporting biotechnology learning for pre-service biology teachers.Abstrak: Penelitian ini bertujuan untuk mengungkapkan persepsi dan kebutuhan calon guru biologi terhadap pembelajaran bioteknologi dan kebutuhan mereka akan media pembelajaran khususnya pada topik teknik dasar biologi molekuler. Penelitian kuantitatif deskriptif ini dilakukan secara purposive pada 42 mahasiswa yang telah menyelesaikan perkuliahan bioteknologi di Program Studi Pendidikan Biologi Universitas Negeri Malang. Instrumen pengumpulan data terdiri dari kuesioner survei kesulitan topik bioteknologi dan kuesioner kebutuhan yang dirasakan (felt needs). Data tanggapan angket yang dianalisis menggunakan statistik deskriptif menunjukkan bahwa tingkat kesulitan aktivitas laboratorium teknik dasar biologi molekuler dianggap dalam kategori sedang. Rata-rata semua siswa melakukan teknik analisis DNA, dan hanya 55% dari seluruh siswa yang melakukan teknik analisis protein. Secara keseluruhan, siswa memiliki perasaan, pemahaman, dan kepercayaan diri pada tingkat sedang, sementara mereka merasa memiliki bantuan belajar yang sangat baik. Meski begitu, mahasiswa merasa membutuhkan sumber belajar berupa multimedia berbasis penelitian untuk mendukung pembelajaran pada topik praktikum teknik analisis biologi molekuler khususnya teknik analisis protein. Multimedia teknik analisis protein berbasis penelitian yang sesuai untuk perkembangan kognitif mahasiswa dinilai dapat dikembangkan dalam mendukung pembelajaran bioteknologi bagi calon guru biologi.

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

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

Tarakan sea waters have geographical circumstances and landscapes that supported the existence richness of fishes that abundant and diverse. There is local fish called Pepija or Lembe-Lembe, but biological studies on this fish most poorly known. This research is aimed to identify the morphological characters of Nomei (Harpodon sp.). Based on specific caharcter, morphometric, and meristric characters. Morphometrics analysis can be used to clustering and understanding relationship of taxa. Each species represented 10% samples of male and female from each type we found and measured 35 characters (in mm). The canonical, clustering and similarity were used. Based on determinant morphological characters species (pectoral fin length reaches or exceeds the initial dorsal fin, dorsal fin earlier than ventral fins), dendogram morphological characters, meristic characters, PCA grouping proved that Nomei fish from Amal and Juata as Harpo-don nehereus.

Dynamics of compound 1,3-Î²-glucan in Agaricus Blazei Murill (ABM) powder and the effect of renal and hepatic histopathology performed on 24 male rats aged 2 months, were randomly conducted in three treatments there are control, ABM powder, and the pure compound 1.3-Î²-glucan for 28 days. Provision of treatment given in the morning and then 1, 3, 8, 12, and 24 hours after administration of treatment blood was collected, while for urine and feces were collected every 8 hours. Giving treatment was continued until day 28. The results showed that the levels of 1,3-Î²-glucan in pure compounds is higher than the Agaricus Blazei Murill (ABM) powder. The effects on the kidneys and liver histopathology showed that cells necrosis more on pure compounds from the mushroom powder gods, both the kidneys and liver. This study shows that the use of pure compounds to be more careful than Agaricus Blazei Murill (ABM) powder in determining the doses used.
