"Tujuan penelitian ini adalah untuk mempelajari pengaruh kondisi proses pengeringan terhadap mutu simplisia temu lawak (Curcuma xanthorrhiza Roxb.) dan menentukan kondisi proses pengeringan terbaik untuk menghasilkan simplisia standar Kriteria kondisi tersebut adalah yang dapat memenuhi kadar air standar 10%, waktu pengeringan yang relatif cepat, hasil pengeringannya masih mengandung kadar kurkumin yang tinggi dan penyusutan serta tampilan visual yang optimal. Hasil studi menunjukkan bahwa pada kondisi pengeringan di bawah suhu 50 derajat celcius dan RH diatas 40% kadar air akhir temu lawak tidak dapat mencapai kadar air standar. Rata-rata penyusutan luas permukaan simplisia temu lawak selama proses pengeringan adalah 66,2%. Terdapat kecenderungan semakin rendah suhu dan semakin tinggi RH pengeringan maka semakin tinggi kadar kurkumin simplisia temu lawak. Kondisi proses pengeringan simplisia temu lawak yang direkomendasikan adalah pada suhu 50 derajat celcius dan RH 30%."

"The study was aimed to determine a proper time of measuring soybean nitrate reductase activities, and to what extend direct and indirect effect of those traits to the soybean yield and its component.The experiment was arranged in Randomized Completely Block Design with three blocks as replications. Six soybean varieties: Burangrang, Wilis, Tanggamus, Cikuray, Mallika, and Gamallika were used. In-vivo nitrate reductase activities were measured at seedling stage (14 dap), when root nodule start to be active (25 dap), maximum growth stage (34 dap), flowering stage (42 dap), and grain filling period (63 dap). Correlation and path analysis was applied to the data collected to determine direct and indirect effect of nitrate reductase activity, growth and yield components to the soybean yield.The results showed that the proper time of measuring nitrate reductase activity was at 42 dap (flowering stage). Large direct effect to grain yield per plant was indicated by seed number per plant, total dry weight, 3-seeded pods per plant and nitrate reductase activity total leaf fresh weight at 42 dap; meanwhile, number of filled pods per plant, number of branch per plant, and number of productive node per plant had a negative direct effect but the indirect effect was larger through seed number. It indicated that the seed number per plant, total dry weight, 3-seeded pods per plant and nitrate reductase activity total leaf fresh weight at 42 dap may be used for soybean yield selection."

"Penelitian ini bertujuan meneliti ekstrak etanol Curcuma aeruginosa Roxb. yang dihipotesakan menjadi terapi alternatif komplementer kanker payudara. Ekstrak dibuat dengan maserasi menggunakan pelarut etanol 96%. Hewan yang digunakan adalah tikus putih betina strain Sprague-Dawley dibagi dalam 9 kelompok yaitu kontrol normal, kontrol DMBA, kontrol doksorubisin, kelompok perlakuan kuratif dan kelompok perlakuan adjuvan. Setiap tikus, kecuali kontrol normal, diinduksi dengan 7-12-dimetilbenz(a)antrasena (DMBA) 20 mg/kgBB sebanyak 5 kali, dua kali seminggu. Masa inkubasi tumor 8 minggu. Kelompok perlakuan mendapatkan ekstrak dalam 3 variasi dosis yaitu 40 mg/200gBB, 80 mg/200gBB dan 160 mg/200gBB. Palpasi dilakukan seminggu sekali. Pada minggu terakhir perlakuan dilakukan pembedahan. Tumor dibuat preparat histopatologi hematoksilin-eosin dan AgNOR. Hasil penelitian menunjukkan bahwa semua kelompok kuratif dan kelompok adjuvan (2 dan 3) berat tumornya lebih rendah secara signifikan (P<0.05) dibandingkan DMBA. Volume tumor kelompok kuratif dosis 1 dan 3 serta adjuvan 2 lebih rendah secara signifikan (P<0.05) dibandingkan DMBA. Skor HE kelompok kuratif dosis 1 dan 3 lebih rendah signifikan (<0.05) dibandingkan DMBA. Nilai mAgNOR dan pAgNOR seluruh kelompok lebih rendah secara signifikan (P<0.05) dibandingkan DMBA. Secara keseluruhan disimpulkan bahwa ekstrak temu hitam dapat menghambat pertumbuhan tumor payudara tikus khususnya kelompok perlakuan kuratif dosis 3 (160 mg/200gBB), meskipun tidak sebanding dengan doksorubisin.

The aim of this study is to investigate the ethanolic extract of Curcuma aeruginosa Roxb. which hypothesised to become complementary alternative therapies for breast cancer. Extracts were made by maceration using ethanol 96%. Animals used were female white rats of Sprague-Dawley strain which divided into nine groups: normal control, DMBA control, doxorubicin control, curative treatment groups and adjuvant treatment groups. Each rat, except for the normal controls, induced by 7-12-dimetilbenz(α)anthracene (DMBA) 20 mg/kgBW 5 times, twice a week. The incubation period of tumors was 8 weeks. Extract in the treatment group were given 3 variant of doses, 40 mg/200gBW, 80 mg/200gBW and 160 mg/200gBW. Palpation done once a week. Surgery was done in the last week of treatment. Histopathological slides of tumor in hematoxylin-eosin and AgNOR staining was made. The results showed that tumor weight of all curative groups and adjuvant groups (2 and 3) was significantly lower (P <0.05) than DMBA. Tumor volume of curative groups dose 1 and 3 and adjuvant 2 significantly lower (P <0.05) than DMBA. HE score of curative groups dose 1 and 3 significantly lower (<0.05) than DMBA. The value of mAgNOR and pAgNOR of the whole group was significantly lower (P <0.05) than DMBA. Overall can be concluded that the extract of temu hitam can inhibit the rat breast tumors growth particularly the curative treatment dose 3 (160 mg/200gBW) although not comparable to doxorubicin."
