    The interaction between genetic and environmental factors in determining the characters of living organism is one of the main concepts in biology nowadays, and it becomes one of the main topic that students learn in genetics lecture. However, the observation result showed that regulation of gene expression in eukaryotes was considered to be a quite difficult topic for the students. The utilization of Drosophila melanogaster through practical activities can be used as an instructional media to help students understand the effect of environmental factors on the characters of living organism. This research aims to prove that through the crossbreeding of D. melanogaster for several generations, the effect of environmental factors on the characters of living organism can be observed. In this research, three strains of D. melanogaster were used to reveal the effect of dark environment on fecundity, which is one of the determinant factors of fitness in insects. The results showed that D. melanogaster treated in dark condition had lower fecundity than that in the control condition. The results of the comparison among the strains also showed that the strains of wild-type had higher fecundity than the white eyed color and ebony strains. The interaction between light conditions and generation and the interaction between light, strains, and generation also had an effect on the fecundity

    Nontext book are books which are not used directly as a book to study particular subject in educational institution. One of nontext books is a supplementary book. Genetics course is a course taught in Biology Education Program of Jember University. There are several problems in the lecture based on the analysis of teaching materials needs. These problems are such as the source of many teaching materials that use English, so the students get difficult in understanding the material, students are looking forward to the material with a simple language and easy to understand, and having interesting illustrations. The purpose of this study is to produce a supplementary book of Genetics in Biology Education Program in University of Jember. The supplementary book which was being developed is a research-based supplementary book with development model R&D Borg and Gall. The supplementary book was validated by a material expert, a development expert, and tested on a small group of 15 students. The result of material validation showed the value of 81,39%, developing validation 97,96%, and the result of reading test 73,66%. Overall, the supplementary book is valid enough with a little revision. The revised book is based on suggestions and comments provided by validators and test of small group of students.Nontext book are books which are not used directly as a book to study particular subject in educational institution.

    Kadmium dan Efeknya terhadap Ekspresi Protein Metallothionein pada Deadema Setosum (Echinoidea; Echinodermata)

    Logam berat kadmium (Cd) bersifat karsinogen, mutagenik dan teratogenik pada beberapa jenis hewan. Ketika berada di dalam sel, Cd akan menginduksi berbagai jenis mekanisme signal transduksi serta mengaktifkan banyak gen. Salah satu efek langsung yang ditimbulkan oleh Cd adalah mengganggu proses homeostasis sel. Mekanisme homeostasis sel terlaksana dengan keberadaan protein metallothionine (MT) yang berperan sebagai protein pengikat logam dan mengurangi efek toksik. Tujuan dilakukan penelitian ini adalah untuk mengetahui konsentrasi Cd pada kompartemen tubuh Deadema setosum sekaligus mengkaji efek Cd terhadap ekspresi protein metallothionein pada D. setosum. Hasil analisa kandungan Cd dalam kompartemen tubuh D. setosum menunjukan rerata kadar Cd bervariasi namun pada cangkang (0.67) < duri (0.75) < gonad (1.35) < usus (1.63). Hasil pemulasan imonohistokimia menggunakan antibodi rabit anti MT-1 D. setosum menunjukan sel yang mengekspresikan MT-1 berwarna coklat. Ekspresi protein MT-1 pada gonad, usus, dan hepar menunjukan perbedaan morfologi sel, dimana Cd yang terakumulasi pada setiap sel tergat tergantung pada jenis dan fungsi organ selnya
