The accuracy of using the media indirectly will stimulate students to take part in these lessons so that it will affect the good and bad results of student learning. The research design used Two Group Randomized Subjeck Posttest Only, by selecting two classes, namely the experimental class group and the control class group. The experimental class group used Flipchart learning media while the control class used conventional learning models. The same test was given to both classes, namely at the end of the lesson (posttest). From the results obtained, it is known that the cognitive learning outcomes of students using flipchart learning media are much better than students who use conventional learning models. This can be seen from the average score of the experimental class which is much higher than the control class, which is 80.44, while the control class is 58.93. From the results of hypothesis testing, it shows that tcount = 4.26 and ttable = 1.67 at the significant level α = 0.05 with degrees of freedom dk = (34+ 34-2). Based on the criteria for the hypothesis accept H0 if tcount <ttable with degrees of freedom dk = (n_1 + n_ (2) - 2) with a significant level α = 5% for other t values H0 is rejected. Judging from the results of the calculation, it is known that the value of tcount> ttable. So that H_ (0) is rejected and H1 is accepted, which means that there is an effect of Flipchart learning media on cognitive learning outcomes of class X students of SMA Negeri 24 Maluku Tengah. Abstrak. Ketepatan penggunaan media secara tidak langsung akan menimbulkan rangsangan dari diri siswa untuk mengikuti pelajaran tersebut sehingga akan mempengaruhi baik buruknya hasil belajar siswa. Desain penelitian ini menggunakan Two Group Randomized Subjeck Posttest Only, dengan memilih dua kelas yaitu kelompok kelas eksperimen dan kelompok kelas kontrol. Kelompok kelas eksperimen menggunakan media pembelajaran Flipchart sedangkan kelas kontrol menggunakan model pembelajaran konvensional. Tes yang sama diberikan pada kedua kelas yaitu pada akhir pembelajaran ( postes). Dari hasil yang didapat diketahui hasil belajar kognitif siswa yang menggunakan media pembelajaran Flipchart jauh lebih baik daripada siswa yang menggunakan model pembelajaran konvensional. Hal ini dilihat dari rata-rata skor kelas eksperimen yang jauh lebih tinggi dari kelas kontrol yaitu 80.44 sedangkan kelas kontrol 58,93. Dari hasil pengujian hipotesis menunjukan bahwa thitung = 4.26 ttabel = 1.67 pada taraf singnifikan = 0,05 dengan derajat kebebasan dk = (34+ 34 - 2 ). Berdasarkan kriteria hipotesis terima H0 jika thitung < ttabel dengan derajat kebebasan dk = ( + - 2 ) dengan taraf signifikan = 5% untuk nilai t lainnya H0 ditolak. Dilihat dari hasil perhitungan yang didapat diketahui nilai thitung ttabel Sehingga demikian ditolak dan H1 diterima yang artinya bahwa ada pengaruh media pembelajaran Flipchart terhadap hasil belajar kognitif siswa kleas X SMA Negeri 24 Maluku Tengah.
Kandungan senyawa metabolisme sekunder pada tanaman sering digunakan sebagai bahan antibiotik dan untuk mendapatkan senyawa metabolisme sekunder dilakukan proses ekstraksi maupun fraksinansi. Penelitian ini bertujuan untuk mengetahui, (1) kandungan flavonoid beserta kadar flavonoid pada fraksi dari sampel daun sirih hijau; (2) fraksi yang paling aktif dalam menghambat aktifitas bakteri Salmonella typhi; (3) jenis senyawa yang terdapat pada fraksi aktif dan struktur molekulnya. Penelitian ini merupakan penelitian eksperimen dimana hasil penelitian akan dideskripsikan secara keseluruhan. Hasil analisis menunjukan dari empat fraksi yang diperoleh dari sampel daun sirih hijau tiga diantaranya mengandung senyawa flavonoid dengan kadar flavonoid tertinggi terdapat pada fraksi M1yaitu sebesar 51,4108 % b/b. Hasil pengujian antibakteri menunjukan bahwa fraksi terbaik dari sampel daun sirih hijau adalah fraksi metanol pada konsentrasi 62,2 µg/ml memiliki zona hambat sebesar 4,3 mm dengan berat molekul tertinggi terdapat pada senyawa Galic acid dan rumus molekulnya C7H6O5.
Mustard is a vegetable with high economic value, including mustard pakcoy (Brassica rapa subsp, chinensis), mustard petsai (Brassica chinensis L), and white mustard (Brassica rapa subsp, pekinensis). To meet consumer needs, it is necessary to increase the production of mustard through organic farming by implementing an agricultural system that utilizes water hyacinth in the form of liquid organic fertilizer. Water hyacinth is an aquatic weed so an alternative is needed to reduce its population by using it as a liquid organic fertilizer with a bio-activator Trichoderma sp. The purpose of the study was to measure plant height, number of leaves, leaf width, and wet weight of mustard pakcoy, mustard petsai, and white mustard. The design of this study used a single factor RAL, namely giving water hyacinth POC with bio-activator Trichoderma sp on 3 types of mustard, with 3 levels, namely A = 32 ml/L (mustard pakcoy), B = 32 ml/L (mustard petsai), C=32 ml/L (white mustard) which was repeated 5 times. Research proves that giving water hyacinth POC with bio-activator Trichoderma sp 32 ml/liter has a significant effect on the height and width of white mustard leaves. For the number of leaves and wet weight, giving water hyacinth POC with bio-activator Trichoderma sp 32 ml/liter had a significant effect on mustard pakcoy compared to other mustards. This means that POC with bio-activator Trichoderma sp can be used as an environmentally friendly liquid organic fertilizer, especially for mustard pakcoy and white mustard which can stimulate plant growth and productivity.
Mustard greens (Brassica rapa var. Parachinensis) are known vegetables among consumers and have high economic value. Besides being used as a vegetable, mustard greens are also used for the treatment of various diseases so that they are included in the vegetable group which has an important role in meeting the needs of food, nutrition and medicine for the community. To increase the growth and production of green mustard plants, it is necessary to apply liquid bio-organic fertilizers that are sourced from organic materials with good nutrients needed by plants, one of which is water hyacinth weed. To improve the quality of water hyacinth liquid bio-organic fertilizer, it can be applied with the bio-activator Trichoderma sp which functions to produce liquid bio-organic fertilizer with high nutrients for plant growth and production. The purpose of this study was to determine the growth of mustard greens including plant height, number of leaves and leaf width and to test the production of mustard greens including caratenoids and vitamin C content. This study used a completely randomized design (CRD) with a single factor, namely fertilizer. Liquid organic (POC) water hyacinth fermented using Trichoderma sp. which consists of 5 levels of fertilization doses, namely A (0 ml / L), B (8 ml / L), C (16 ml / L), D (24 ml/L) and E (32 ml/L) with 5 repetitions. Based on the results of analysis of variance, it showed that the dosage treatment of water hyacinth bio-organic fertilizer with the bio-activator Trichoderma sp had a significant effect on p <0.05 on plant height, leaf width and the number of green mustard leaves at 4 weeks of age 21 day after planting. with the results of the chemical content test which showed that treatment E (32 ml/L) contained Karetenoid (0,2596 mg/100g of material) and vitamin C (0.2784 mg/100 g of material). The best dose based on the results of the study was treatment E (32 ml/L) which had a higher average plant height, leaf width and number of leaves compared to other treatments and had high vitamin A and vitamin C content. To increase the growth and production of mustard greens and other horticultural cultivation processes, it is advisable to use liquid bio-organic fertilizer for water hyacinth with the bio-activator Thricoderma sp as an alternative to natural, environmentally friendly liquid organic fertilizer.
