Cassava Brown Streak Disease (CBSD) is a major disease in cassava plants which have the serious problems in cassava plantations in the world, especially in Africa, Tanzania and India (Wassawaet., al, 2010). In Indonesia, the virus is still not optimal yet in the handling. The disease is present in plants that can destructive cassava leaves, stems and tubers. It was greatly reduces the quality and production in the world such as India. The decrease of cassava yield can reach 100% due to disease of CBSD (Lopez, 2003). The primer was designed from the coat protein gene of CBSD with a distance of 380 bp (Abarshiet.,al, 2012). The primers designed the forward primer (GGARCCRATGTAYAAATTTGC) and Reverse (GCWGCTTTTA TYACAAAMGC). The RNA isolation have been used Plant Virus RNA Kit (Geneaid). The CBSD RNA concentration around 55,2ng/ul. The RT PCR program were one cycle of RT PCR reaction (45oC for 30 min), denaturation (45oC for 5 min) and 30 cycles for denaturation (94oC for 1 min), annealing (52oC for 30 sec), extention (72oC for 1 min). The results showed a single band of about 380 bp which is the distance between the two primers were tested. The multiplication shoot around 5 shoots per meristem explants with a combination of 0.5 ppm and 0.1 ppm BAP GA3 Keyword : Cassava Brown Streak Disease (CBSD), CASSAVA (Manihotesculentum), RT PCR

Abstract : Improving Student Learning Outcomes Using Project Based Learning Method. Based on the problems experienced by the students, it appears that the thought to emphasize the learning that can produce learners who have enough knowledge, so as to reveal ideas or ideas in solving the problem of IPA through the model of PJBL (Project Based Learning). The research procedure applied is Classroom Action Research (PTK) which means improvements made in certain classes that will be studied and given action directly. This activity through four stages: planning, implementation, observation and reflection. Data collection techniques conducted by the author using data collection tools such as: 1). Observation or observation is the activity of recording phenomena done systematically. 2). Researchers use quantitative descriptive analysis techniques. Through Project Based Learning method can improve science learning outcomes of fourth grade students B SDN Plumbon 01 District Suruh regency Semarang 2016/2017 academic year. Keywords : Learning outcomes, Project Based Learning Abstrak : Meningkatkan Hasil Belajar Siswa Dengan Menggunakan Metode Project Based Learning. Berdasarkan permasalahan yang dialami siswa maka munculah pemikiran untuk menekankan pembelajaran yang dapat menghasilkan peserta didik yang cukup memiliki bekal pengetahuan, sehingga mampu mengungkapkan gagasan atau ide-idenya dalam memecahkan permasalahan IPA melalui model PJBL (Project Based Learning). Prosedur penelitian yang diterapkan adalah Penelitian Tindakan Kelas (PTK) yang berarti perbaikan yang dilakukan di kelas tertentu yang akan diteliti dan diberi tindakan secara langsung. Kegiatan ini melalui empat tahap yaitu: perencanaan, pelaksanaan, observasi dan refleksi. Teknik pengumpulan data yang dilakukan oleh penulis dengan menggunakan alat pengumpulan data seperti: 1). Observasi atau pengamatan merupakan aktivitas pencatatan fenomena yang dilakukan secara sistematis. 2). Peneliti menggunakan teknik analisis deskriptif kuantitatif. Melalui metode pembelajaran Project Based Learning dapat meningkatkan hasil belajar IPA siswa kelas IV B SDN Plumbon 01 Kecamatan Suruh kabupaten Semarang tahun ajaran 2016/2017.

Abstract: Application Of Inkuiri Learning Model Assisted To Improve Media Learning Learning Results 5th grade SD. The purpose of this study is to describe the application of inquiry model of media-aided learning to improve the learning outcomes of science students 5th grade elementary school. The subjects of the study were 5th graders, which were 18 students. Classroom action research was conducted in two cycles by applying the media-aided inquiry model. Data analysis techniques applied are guidelines for observation and test of learning outcome, in the form of multiple choice test and essay. The result of the research shows that the application of inquiry model of media-assisted learning can improve the students' learning achievement. Cycle I average test scores 79 with completeness reached 67% and the average test II cycle 84 with completeness reached 92%, so research shows that the model of inquiry learning media can help improve the completeness of student learning outcomes.Keywords: Inquiry learning model, Media, Learning outcomesAbstrak : Penerapan Model Pembelajaran Inkuiri Berbantuan Media Guna Meningkatkan Hasil Belajar IPA Kelas 5 SD.
