Pengembangan Modul Berorientasi Poe (Predict, Observe, Explain) Pada Materi Pencemaran Untuk Meningkatkan Hasil Belajar Siswa

Penelitian ini bertujuan untuk mengetahui hasil prosedur pengembangan modul berorientasi POE pada materi pencemaran, kelayakan modul, efektivitas modul, dan perbedaan hasil belajar siswa sebelum dan setelah penerapan modul. Penelitian ini menggunakan metode Research and Development (R&D) yang mengacu pada model Borg & Gall yang telah dimodifikasi. Sampel pengembangan meliputi sampel validasi produk sejumlah 4 validator, sampel uji coba terbatas sejumlah 10 siswa, dan sampel uji coba lapangan sejumlah 32 siswa. Teknik pengumpulan data yang digunakan adalah angket untuk analisis kebutuhan, validasi ahli, dan tanggapan siswa terhadap modul; lembar observasi untuk hasil belajar psikomotorik, afektif, dan keterlaksanaan sintaks; wawancara untuk analisis kebutuhan, tanggapan siswa terhadap modul saat uji coba terbatas, dan lapangan; dan tes untuk hasil belajar kognitif. Uji coba lapangan menggunakan one group pretest-posttes design. Data hasil belajar kognitif dihitung dengan gain ternormalisasi dan diuji dengan uji t dua sampel berpasangan, sedangkan hasil belajar psikomotorik dan afektif hanya dihitung persentase ketercapaiannya. Berdasarkan hasil penelitian dapat disimpulkan bahwa: 1) pengembangan modul berorientasi POE pada materi pencemaran menggunakan model Borg & Gall yang telah dimodifikasi melalui tahapan research and information collection, planning, develop preliminary form of products, preliminary field testing, main product revision, main field testing, dan operational product revision, 2) kelayakan modul pembelajaran yang dikembangkan mendapatkan nilai 3,3 setelah dilakukan uji lapangan dan berkategori “Baik”, 3) pencapaian hasil belajar siswa mengalami peningkatan yang signifikan dalam kategori “Sedang”, dan 4) setelah dilakukan uji secara statistik diperoleh adanya perbedaan hasil belajar siswa, sebelum dan setelah diterapkan modul berorientasi POE

Diferensial Leukosit Ikan Gurami (Osphronemus Gouramy Lac.) Dengan Perbedaan Level Suplementasi Spirulina Platensis Dalam Pakan

The aim of this research was to know the effect of supplemented Spirulina platensis in diet on leukocytes differential of gourami (Osphronemous gouramy Lac.) and to obtain the best dose. This research was carried out experimentally using a completely randomized design (RAL), which consists of 4 treatments and 3 repetitions. The fish fed with diets which contain different levels of (0, 2.4, and 6g/kg) Spirulina platensis were investigated. Sampling was done 4 times at intervals of 2 weeks of the feeding experiment, leukocyte differential (monocyte, lymphocyte, neutrophil, eosinophyl) of blood taken from fish were determined. The results showed that the highest percentage of lymphocytes was found in level of supplementation of 4 g/kg of diets, whereas the highest percentage of monocytes, neutrophils and eosinophils were found at the level suplemetation 2 g/kg of diets. Level supplementation of S. platensis 4 g/kg of diets is an efficient and effective level in stimulating immune system cells of gourami, particularly lymphocytes cell

The Study Biological Aspects of Parapenaeopsis Coromandelica on Cilacap Water, Central Java

Kabupaten Cilacap merupakan salah satu kabupaten yang memilki potensi yang tinggi di bidang perikanan tangkap karena terletak di pesisir pantai selatan Pulau Jawa dimana terdapat pangkalan perikanan yang terbesar. Pemanfaatan udang P.coromandelica yang terus meningkat, menyebabkan tingginya intensitas penangkapan dan menurunnya daya dukung lingkungan perairan Kab. Cilacap, hal ini memungkinkan perkembangan stok dari jenis udang ini terhambat. Tujuan dari penelitian ini adalah untuk mengetahui aspek biologi, status pemanfaatan dan konsep pengelolaan udang P. coromandalica di perairan Cilacap. Metode penelitian yang digunakan adalah metode survey, dengan teknik pengambilan sampel secara simple random sampling yaitu mengambil sampel udang sekitar 10% dari total hasil tangkapan salah satu alat tangkap jaring arad pada setiap TPI. Jenis data yang digunakan yaitu data primer dan data sekunder. Penelitian ini dilakukan pada bulan September – Desember 2012. Hasil penelitian menunjukkan bahwa Pertumbuhan udang P.coromandelica jantan dan betina memiliki nilai b 1,657 dan 2,22 ini menunjukan bahwa pertumbuhan udang bersifat allometrik negative. Sebagian besar udang P.coromandelica belum matang gonad dan belum siap memijah. faktor kondisi untuk udang P.coromandelica jantan dan betina menunjukkan 1,054 dan 1,117 bahwa tubuh udang kurus. Nisbah kelamin jantan dan betina adalah 1 : 1,545 artinya bahwa perairan Kab. Cilacap tersebut masih normal. Nilai Lm 41 mm, Lc50% 37 mm dan nilai L∞ jantan dan betina adalah 53,68 mm dan 64,21mm. Nilai Lc50% lebih besar dari nilai setengah L∞, itu berarti udang P. coromandalica sudah layak tangkap

PRODUKTIVITAS DUA JENIS JANGKRIK LOKAL Gryillus testaceus Walk. DAN Gryllus mitratus Burn. (Orthoptera: Gryllidae) YANG DIBUDIDAYAKAN

Study on the productivity of two species of local crickets; Gryllus testaceus Walk and Gryllus mitratus Burn which are generally found in the local market have been conducted with the main aim at obtaining information on the capability of those species in producing eggs including the length of production cycles.Three levels of box square density (50 female/box,100 female/box and 150 female/box) and two levels of additional feed (green master and papay leaves) were used as treatments.The results showed that the number of eggs produced by G.mitratus were larger with longer production cycles compared to those of G.testaceus. Species and density has highly significant effects on egg production and feed consumption, whereas,additional feed significantly influencing egg production and feed consumption of the two species.The use of green master as additional feed resulted in a higher egg production than those given papay leaves
