This Research purpose is to get the proof of the Development of teaching tool through CTL approach shows decrease of misconception after the learning. The amount of research subject contains 75 students from three classes, they are XII Scienc e 1, XII Science 4, and XII Science 5 in SMA Negeri 1 Surabaya. The research has been done with CRI (Certainty of Response Index) method for measuring the Student’s misconception. The research result shows the student’s misconception of Dynamic fluid happened on the concept at the beginning of learning before the CTL approach. The average percentage of misconcepti on on the three classes replication shows on the continuity equation shows 26.4 %, on the Bernoulli principal with the application of the Bernoulli, which is Torricelli theory shows 25.3 % of misconception , and on the next concept of application of Bernoulli principal which is Venture meter shows 30.7% of misconception, and on the Aircraft’s wing lifting shows 10.7% of misconception. On General Student Misconception happened on Dynamic fluid shows decrease level of misconception even though there are still few students on the three classes on the three replication classes shows increase of misconception level. The conclusion is Physic teaching and l earning through CTL approach can minimize the misconception level for Students on Dynamic fluid subject.Penelitian ini bertujuan untuk memperoleh bukti dengan mengembangkan perangkat pembelajaran melalui pendekatan CTL agar terjadi penurunan miskonsepsi sesudah pembelajaran. Subyek penelitian berjumlah 75 siswa dari tiga kelas paralel yai tu kelas XII IPA1, XII IPA4, dan XII IPA5 di SMA Negeri 1 Surabaya. Penelitian dilakukan dengan metode CRI (Certainty of Response Index) untuk mengukur miskonsepsi siswa. Hasil penelitian menunjukkan miskonsepsi siswa pada materi fluida dinamis terjadi pada sebagian besar konsep di awal sebelum pemberian pembelajaran CTL. Persentase rata-rata miskonsepsi pada ketiga kelas replikasi, menunjukkan pada konsep persamaaan kontinuitas menyisakan miskonsepsi sebesar 26,4%, pada konsep asas Bernoulli beserta penerapannya yaitu Teori Torricelli masih menyisakan miskonsepsi sebesar 25,3%, dan pada konsep penerapan asas Bernoulli yang berikutnya yaitu pada pipa venturimeter masih menyisakan miskonsepsi sebesar 30,7%, dan gaya angkat sayap pesawat terbang masih menyisakan masing-masing 10,7%. Pada umumnya miskonsepsi siswa pada materi fluida dinamis mengalami penurunan meskipun ada beberapa siswa pada ketiga kelas replikasi mengalami kenaikan jumlah miskonsepi. Sehingga dapat disimpulkan bahwa pembelajaran fisika melalui pendekatan CTL dapat meminimalisir miskonsepsi siswa pada materi fluida dinamis

The research purpose to know about sodium benzoate and then determine content level existence on samples of sauce bottle on Beringharjo market in Yogyakarta. Research methods: The research describe sodium benzoate exiztence on sauce and than determine sodium benzoate level on saos. The research object sodium benzoate. Statistical variable in this research is one variable that is the existence and level of sodium benzoate on samples. Method that used for analyzed sodium benzoate in this case is base-acid titration in alkalimetry with two test that is qualitative test and quantitative test. This data is set out in table. Result: The research result by samples is 100% contain sodium benzoate and preservative with high level or out of maksimum level that has been certained and did not fulfill the terms of regulation BPOM Nomor 36 Tahun 2013 is 41,70%. Conclusion: there is sodium benzoate preservative on samples of sauce bottle on Beringharjo market in Yogyakarta with level maximum 7.001,61 mg/kg and level minimun 420,175 mg/kg

Introduction: Livestock population in Magetan, East Java Province, Indonesia is quite high, which is 58.671 animals This can be become a potency for development of organic fertilizer with fresh cow dung as the raw material. For producing biogas from cow dung, it needs to be conducted appropriate technological innovation, thus, it can be used and can reduce environmental pollution. Methods: The research’s method was eksperimental research. Purpose: Identifying the measuring the levels of: macronutrient of organic fertilizer in this research: N, P, K, and C-organic. Analyzing exact fermentation time in making organic fertilizer from variation in the comparison of molasses. Result: The organic levels of N, P, K and C showed that it qualified the standard of Regulation of the Ministry of Agriculture Number 70/ PERMENTAN / SR.140 / 102011. Based on the research result, it was obtained that the fastest of fermentation time was in variation 4 with the comparison of addition of molasses dose in 200 ml and EM4 in 50 ml.
