The purpose of this study was to determine the development phases of S. bracteosa flower and fruit. The study was conducted by observing structural characteristics of flower and development stages from flower until ripe fruit. Phenology of flower and fruit development were classified into five stages namely flower initiation, small bud stage, large bud stage, anthesis, and fruit development. Changes in color, shape, size, and time period of each stage in twenty inflorescences of four plants were observed. The period from flower initiation to fruit maturity of S. bracteosa took on average 145 days. Flower initiation took on average 16 days, small bud stage occurred in 38 days, large bud phase occurred in 16 days, anthesis stage took on average 5 days and fruit development would complete in 74 days.

Metode penelitian yang digunakan adalah metode kuantitatif Quasi Experimental Design dengan bentuk desain penelitian Nonequivalent Control Group Design. Populasi terdiri dari seluruh kelas VIII yang berjumlah 126 siswa, dengan sampel yang digunakan adalah teknik sampel purposive sampling. Data dalam penelitian ini diperoleh melalui instrumen tes hasil belajar berupa tes pilihan ganda. Teknik analisis data hasil belajar menggunakan statistik deskriptif dan statistik inferensial dengan uji-t untuk menguji hipotesis penelitian. Hasil penelitian ini menunjukkan bahwa terdapat perbedaan peningkatan yang signifikan hasil belajar antara siswa ya...

Rumah sakit di Indonesia belum banyak melaporkan tentang kejadiannya. Rendahnya ketertarikan ibu terhadap bayinya merupakan dampak dari postpartum blues. Penelitian ini bertujuan untuk mengidentifikasi hubungan kejadian postpartum blues dengan motivasi ibu untuk menyusui di RS Al-Islam Bandung. Metode penelitian yang dilakukan adalah deskriptif korelasi dengan pendekatan cross sectional yang melibatkan 122 ibu postpartum hari ke-3 sampai hari ke-14. Instrumen untuk postpartum blues menggunakan Edinburgh postnatal depression scale (EPDS) dan motivasi menyusui dengan instrumen Breastfeeding motivation instrucsional measurement scale (BMIMS). Data dianalisis dengan korelasi Spearman rank. Hasil penelitian menunjukan bahwa 53,3% dari 122 responden mengalami postpartum blues, dan dari 65 responden yang mengalami postpartum blues 36 orang (55,4%) memiliki motivasi menyusui yang rendah. Hasil uji korelasi men...

Pierre) is one of the most potential biodiesel raw materials to be developed in Indonesia. The plant is naturally distributed from Sumatera to Papua. However, oil content and its physico-chemical properties of malapari originated from Java was limitedly known. This study investigates chemical composition of malapari seeds, identifies fatty acid composition of the produced seed oil and characterises physico-chemical properties of malapari oil. Composition of chemical content of malapari seeds was analyzed through proximate analysis. Physico-chemical properties of malapari oil were analyzed using the ASTM test method. Results showed that Batukaras population is the best population to be used as biodiesel raw material source because it has the highest value of oil content. Besides, the Batukaras population has the lowest specific gravity, viscosity and acid value. Malapari oil is dominated by oleic and linoleic fatty acids which are potentially unsaturated fatty acids for biodiesel. Value of fatty acids (oleic and linoleic) and physico chemical properties (specific gravity and calorific value) of pongamia crude oils suggested that the five populations have been eligible for biodiesel feedstock.
