Gastropoda is molusca member as benthic animal. The diversity of the animals role as bioindicator of marine ecosystem. The objectives in this research is to identify the species of Gastropoda and to know the diversity, density, and dominancy in three research stations around at Mimbo beach, Situbondo district, and to know the influence of environment factors on diversity, density, and dominancy of the Gastropoda . The data collecting used plot transect method. Plot had size 1 × 1 m². There were 3 transects for every stations, located about 50 m from shoreline horizontaly into the sea. Result of the research revealed that there were five Gastropodas consisted of 277 individuals which spread in three stations. The total of Gastropoda diversity showed a middle category (H’ = 1,0289). Population density of Gastropoda was 6,1 individual/m², dominancy of Gastropoda was very low (C = 0,3154). Environment factors such as temperature, dissolved oxygen, pH, salinity, and light intensity had significant influnce on diversity and dominancy of Gastropoda, but not for its density.

Pembelajaran IPA hendaknya disajikan dalam bentuk utuh. Pembelajaran IPA yang dilakukan di SMPN 2 Balung Jember masih terpisah-pisah antara fisika, kimia dan biologi, banyaknya materi yang belum terselesaikan membuat guru merasa takut melakukan kegiatan praktikum, guru sering menggunakan metode ceramah dan terlihat kurang antusias dalam mengajar dengan hanya fokus pada materi bahan ajarnya yang sudah dipersiapkan tanpa mementingkan interaksi dengan siswa. Antusiasme seorang guru dalam mengajar merupakan faktor yang penting untuk menumbuhkan motivasi dalam diri siswa sehingga hasil belajar siswa akan bertambah.  Dari permasalahan tersebut, peneliti ingin meningkatkan motivasi dan hasil belajar siswa menggunakan penerapan pembelajaran terpadu model terhubung.
