Wullur1), Widya Astuty Lolo1) 1)Program Studi Farmasi FMIPA UNSRAT Manado, 95115 ABSTRACT Pineapple rind (Ananas comosus L. (Merr).) contains flavonoid and tanin that can be used as sunscreen. This research aims to make sunscreen lotio from pineapple rind extract with concentration of 8, 10 and 12% base on lotio requirements including organoleptic test, homogeneity test, pH test, dispersive test and examine the pineapple rind extract lotion as sunscreen by measurement of Sun Protection Factor (SPF) value in vitro. Pineapple rind with concentration at 8, 10 and 12% can be formulated as lotion. The lotion were made based on lotion requirements including organoleptic test with semisolid phase, greenish yellow in color and specific fragrance of pineapple. Homogeneity test with the absence of small particles through out all the lotion; pH test was 6 which still within skin pH interval of 4-7,5 and dispersive test with dispersive diameter width of 6-7 cm indicated the semisolid consistency which is comfortable in use. The effectiveness of the sunscreen were carried out by the determination of SPF value using Spectrophotometer UV-Vis method. All the lotion meet the requirements as sunscreen with SPF value of 2,66; 2,72 and 2,83 respectively. Keywords : Lotion, Pineapple Rind, Sunscreen, SPF ABSTRAK Kulit buah Nanas (Ananas comosus L.

Selasia dembickyi sp. nov. is the only Drilini species known from South East Asia. It can be recognized by the following combination of characters: head and pronotum lighter than rest of body (Figs 1–2), weakly flabellate antennae (Fig. 5), strongly sinuate pronotal sides with distinctly diverging posterior angles (Fig. 7), and base of sternite IX not emarginate (Fig. 9). This species has uniquely shaped male genitalia among Drilini (Figs 12–13) with a very long and narrow median lobe, which is distinctly longer than the parameres, elongate parameres which are widest at the second third, and the phallobase which is short compared to the median lobe and parameres. Etymology. The specific epithet is a patronym in honor of Luboš Dembický (Brno, Czech Republic), the collector of the holotype. Collecting circumstances. Members of Selasia are usually collected at light or using Malaise traps (e.g., WITTMER 1989; KUNDRATA 2012a, 2017; TRLLOVA & KUNDRATA 2015). The exact collecting circumstances for S. dembickyi sp. nov. are not known but it was most probably collected at light or using a flight interception trap (L. Dembický, personal communication). The habitat of this species is shown in Figs 18–19. Distribution.

Produktivitas Jamur Tiram Putih (Pleurotus ostreatus) Pada Media Tambahan Limbah Tongkol Jagung (Zea mays L)
No full textJamur tiram merupakan jamur kayu, karena jamur ini tumbuh berawal dari kayu yang telah lapuk. Jamur ini disebut jamur tiram karena memiliki bentuk seperti cangkang pada tiram. Jagung digunakan sebagai media tambahan yaitu limbah tongkol jagung yang dicampur dengan media standar (bekatul, calsit dan kayu sengon). Dalam tongkol jagung mengandung kandungan nutrisi dan unsur hara yang diperlukan oleh jamur tiram putih (Pleurotus ostreatus) untuk pertumbuhannya. Penelitian ini bertujuan untuk mengetahui pengaruh media
tanam tongkol jagung terhadap pertumbuhan jamur tiram putih. Penelitian ini merupakan desain penelitian pola 1 faktorial dengan 4 perlakuan 3 kali ulangan.

Onkel Remus erzählt . . .
No full textHere is my second German Uncle Remus. It first appeared in Czech from Artia in Prague in 1959. Here are thirty-six episodes on 137 pages, followed by a T of C. The book itself is landscape formatted, 9¼ x 9. On the dust jacket is a long single illustration of four foxes moving right. The front cloth cover has a clever design of a bird on the nose of a fox. The same scene is pictured, though differently, in the full-page colored frontispiece. Besides the frequent colored pictures without printing on their verso, each chapter has one or two simple one-character designs. Over and over we see the rabbit, angry, worried, or suspicious (18, 29, 119). The artist enjoys suggesting that a character runs away or escapes by showing just the rear portion of the animal moving off the page (e.g., 20, 42). One of the best of the colored pictures shows the fox looking down into the well at the rabbit in the bucket (67). The very last page shows the fox inside the stomach of the bull (137).This is a hardbound book (hard cover)This book has a dust jacket (book cover)Language note: GermanZweite AuflageJoel Chandler Harris; ins Deutsche übertragen von Eliska Glaserov
