Abstract

ABSTRAKAntioksidan merupakan senyawa yang dapat menghambat dan mencegahpertumbuhan kanker. Salah satu tanaman yang diduga dapat mengobati kanker adalah pare (Momordica charantina L). Masyarakat telah menggunakan pare sebagai makanan sehari-hari dan juga telah lama dipercaya sebagai obat tradisional untuk mengobati berbagai macam penyakit. Penelitian ini bertujuan untuk mengetahui aktivitas antioksidan dari ekstrak etanol buah, daun, dan biji pare. Buah, daun dan biji pare diekstraksi dengan etanol 70% dan dipekatkan hingga didapatkan ekstrak kental. Pengujian aktifitas antioksidan pada penelitian ini menggunakan metode peredaman terhadap radikal bebas 1,1-difenil-2-pikrilhidrazil (DPPH), dan vitamin C sebagai kontrolnya. Hasil pengujian antioksidan pada vitamin C didapatkan nilai IC50 sebesar2,844 g/mL. Hasil pengujian aktifitas antioksidan dari ekstrak etanol buah, daun, danbiji pare menunjukkan bahwa ketiga ekstrak tersebut tidak memiliki aktifitas sebagai antioksidan. Suatu senyawa dikatakan aktif sebagai antioksidan apabila nilai IC50 < 100 ppm.Kata Kunci : Antioksidan, Pare (Momordica charantina L), DPPH.

Abstract

PEMODELAN MEKANISME UMPAN BALIK REAKTIVITAS PADA SIMULATOR REAKTOR KARTINI. Pengendalian reaktor dilakukan dengan beberapa tahapan seperti mengubah jumlah atau posisi bahan bakar, mengubah moderator atau reflektor serta menambah atau mengurangi bahan penyerap neutron di dalam teras reaktor. Ketiga tahapan tersebut mempengaruhi daya reaktor melalui perubahan nilai reaktivitas yang dikenal sebagai efek umpan balik reaktivitas. Untuk mengetahui efek umpan balik reaktivitas terhadap daya reaktor maka dilakukan Pemodelan Mekanisme Umpan Balik Reaktivitas pada Simulator Reaktor Kartini berbasis LabVIEW. Nilai reaktivitas bahan bakar dan pendingin didapatkan dari data operasi reaktor Kartini mengenai suhu bahan bakar dan pendingin terhadap daya reaktor. Nilai reaktivitas bahan penyerap neutron didapatkan melalui konversi posisi batang kendali penyerap neutron menjadi reaktivitas dengan memanfaatkan data kalibrasi terakhir batang kendali reaktor Kartini. Ketiga nilai reaktivitas tersebut dijumlahkan dan dihitung dalam persamaan kinetika reaktor titik, dan dikonversi menjadi besaran daya reaktor. Efek umpan balik akan mengubah parameter dalam persamaan kinetika, terutama pada nilai reaktivitas total. Model umpan balik reaktivitas telah berhasil dibuat dan menghasilkan daya konstan. Model umpan balik reaktivitas sudah dimasukkan dalam simulator reaktor Kartini. Namun demikian hasil perhitungan daya belum divalidasi dengan daya reaktor Kartini. Kata kunci: umpan balik reaktivitas, simulator reaktor Kartini, pemodelan reaktor titik

Abstract

The surveys of larval parasitiod Plutella xylostella, which have been done in cabbage plantations area in Batu and Poncokusumo, Malang east Java, found other larval parasitoid biside the commonly larval parasitiod Diagdema semiclausum. The parasitoid was Teratichus howardi (Hyminoptera: Eulophidae). The percentage of parasitism was dependent of the altitude of cabbage plantation and developmental stage of crop. The percent of parasitism could reach 82% when parasitized larvae sampled in cabbage plant and the crop stage. Parasitism was also higher at the medium lowland rather than it was that the upland. T. howardi is a gregrarious larval-pupa endoparasitoid. The life cycle of T. howardi was 14-16 days. The longevity of male and female was influenced by the availability of hosts or the change of mating. The longevity of mated female which was offered some host is 14-21 days, but the longevity of mated female without hosts was 38-56 days. The mated male parasitoid lived from 1 to 4 days, but they lived 12-16 days when they were not mated. One female could lay some cluster of egg varied from 35-60 eggs cluster or from 142 to 235 eggs during the lifespan. One eggs cluster consist of ±4 eggs. The parasitoid laid one or two clusters of egg per host. Parasitoid laid eggs soon after mating at day one from eclosion until day 19th. Four to 28 Parasitoids could emerge from one host. One parasitoid was able to parasitize 17-30 larvae of P. xylostella.
