ABSTRACT The purpose of this research was to examine the application of silica in the cultivation of controlled drought stress to obtion simplicia with high flavonoid content. The research was arranged in a completely randomized design with 4x2 factorial with 4 replications. The first factor was drought stress duration consisted of watering every 2 days (controls), 6, 10, and 14 days before harvest. The second factor was the application of silica consisted of without silica (control) and the application of silica with a dose of 150 kg SiO2/Ha. The data were analyzed by variance analysis and continued by Duncan’s Multiple Range Test. The result of the study showed that the aplication of silica increased plant height, number of leaves, fresh weight and dry weight production of simplicia, and flavonoid content. Application of drought stress with a duration of up to 8 days before the simplicia harvested was not reduced plant height, number of leaves, production of fresh weight and dry weight of simplicia, but increased flavonoid content. Application of silica increased the number of leaves and the dry weight of simplicia in the application of drought stress to a duration of zero, 4, and 8 days. The application of drought stress with a duration of 8 days before harvested and silica application increased flavonoid content without reducting the production of dry weight of simplicia.Keywords : binahong, drought stress, flavonoids, silica ABSTRAK Penelitian ini bertujuan untuk mengkaji aplikasi silika pada budidaya tanaman binahong dengan penerapan cekaman kekeringan terkendali untuk memperoleh simplisia dengan kandungan flavonoid tinggi. Penelitian menggunakan rancangan percobaan acak lengkap faktorial 4x2 dengan 4 ulangan. Faktor pertama durasi cekaman kekeringan terdiri dari penyiraman 2 hari sekali (kontrol), 6, 10, dan 14 hari sebelum simplisia dipanen. Faktor kedua aplikasi silika terdiri dari tanpa aplikasi silika (kontrol) dan aplikasi silika dosis 1500 kg SiO2/Ha. Analisis ragam dilakukan dengan uji F dan uji lanjut Duncan Multiple Range Test (DMRT) pada taraf 5%. Hasil penelitian dapat menunjukkan bahwa aplikasi silika meningkatkan tinggi tanaman, jumlah daun, produksi berat segar dan berat kering simplisiaserta kandungan flavonoid simplisia binahong.Penerapan cekaman kekeringan dengan durasi sampai 8 hari sebelum simplisia dipanen tidak menurunkan tinggi tanaman, jumlah daun, produksi berat segar dan berat kering simplisia, tetapi meningkatkan kandungan flavonoid simplisia. Aplikasi silika meningkatkan jumlah daun dan berat kering simplisia pada penerapan cekaman kekeringan sampai durasi nol, 4 dan 8 hari. Penerapan cekaman kekeringan dengan durasi 8 hari sebelum simplisia dipanen dan aplikasi silika meningkatkan kandungan flavonoid simplisia binahong tanpa menurunkan produksi berat kering simplisia.Kata kunci : binahong, cekaman kekeringan, flavonoid, silika

Beauveria bassiana is one of the pathogens that can be used as an environmentally friendly bio pesticide, as it does not produce harmful residues and does not cause pest resistance. This research was conducted in the village of Campursari village, District of Bulu, Temanggung Regency. The purpose of this research was assess the effectiveness of Beauveria bassiana application in order to suppress the population of brown planthopper and adult rice bug in rice plants and to find out rice plants production. The research used factorial randomized design which consists of two treatments. The first treatment was the application of Beauveria bassiana with controlled doses by 0, 100, 150 and 200 g/14 l. The second treatment was the application interval between 7, 10, and 14 days. The parameters observed were brown planthopper populations, adult rice bug population, plant height, number of tillers and grain production. The results showed that application with doses of 200 g/14 l and 7 day interval application was effective to suppress population of brown planthopper and adult rice bug and also saved grain production by 1,20 kg to 7,02 kg/m2 depending on application dosage.

The research was conducted to evaluate the effect of variant of M. anisopliae on mortality of Oryctes rhinoceros and Lepidiota stigma. Variants ofM. anisopliae to be used were Karimun Jawa, Semarang and Magelang (host O. rhinoceros), and UGM (host L. stigma). The research was arranged in factorial experiment withcompletely randomized design, two factors and three replications.The first factor was type variant of M. anisopliae (V0= control, V1= variant UGM, V2= variant Karimun Jawa , V3= variant Semarang , V4 = variant Magelang), the second factor was type of pest (H1 = larva O. rhinoceros, H2 = larva L. stigma). The results showed that each variant of M. anisopliae had the same ability to control O. rhinoceros and L. stigma in both mortality, spore density, and LT50. O. rhinoceros has higher mortality and spore density than L. stigma, but LT50 both pests were the same. The interaction between O. rhinoceros and M. anisopliae gave the highest mortality, spore density, but the same LT50.

The purpose of this research was to analyze the response of growth and production of red rice (Oryza nivara) under drought and nanosilica fertilization condition. This research was conducted in Greenhouse and Laboratory of and Plant Physiology and Breeding of at Faculty of Animal and Agricultural Sciences, Diponegoro University, Semarang from April to July 2017. The research was arranged using completely randomized factorial design. The first factor was drought stress (control, drought 20-35 DAP (Days After Planting), 40-55 DAP and 55-70 DAP). The second factor was the use of nanosilika fertilizers (without nanosilika, with nanosilica). The data were analyzed by anova and followed by Duncan’s Multiple Range Test (DMRT). The results showed that the drought stress during tiller production stage decreased the total number of tillers, productive tillers and grain weight per clump, but not in weight of one thousand seeds. Drought stress during flowering stage and seed filling only decreases the weight of one thousand seeds. Application of nanosilica increases the number of productive tillers and the weight of grain per hill. There was no interaction between drought stress treatment and nanosilika fertilization. Keywords: red rice, production, drought, nanosilica.

Penelitian bertujuan untuk mengkaji pengaruh jumlah ruas stek dan sumber pupuk nitrogen yang berbeda pada pertumbuhan dan produksi simplisia tanaman Kumis Kucing(Orthosiphon aristatus). Rancangan percobaan yang digunakan adalah rancangan acak lengkap pola faktorial. Faktor pertama adalah jumlah ruas batang stek (3, 5, dan 7 ruas) dan faktor kedua adalah sumber pupuk nitrogen (urea, pupuk kandang ayam, pupuk kandang sapi, dan pupuk kandang kambing). Parameter pertumbuhan yang diamati meliputi panjang tunas total, jumlah daun, dan volume akar. Parameter produksi yang diamati yaitu berat daun (simplisia) segar dan kering. Data dianalisis dengan analisis ragam dan dilanjutkan dengan uji berganda Duncan (Duncan’s Multiple Range Test). Hasil penelitian menunjukkan peningkatan jumlah ruas stek mampu meningkatkan panjang tunas total, jumlah daun, dan volume akar. Penggunaan sumber hara nitrogen yang berbeda hanya meningkatkan parameter volume akar. Kedua perlakuan belum mampu meningkatkan produksi simplisia tanaman kumis kucing, serta tidak menunjukkan adanya interaksi pada seluruh parameter penelitian. Kata kunci : Orthosiphon aristatus, Simplisia, Stek, Sumber Nitrogen.

Chrysanthemum is one of popular floriculture commodities in Indonesia. Chrysanthemum is mainly propagated by terminal cutting. This study aimed to investigate the rooting and vegetative growth response of three different cultivars of chrysanthemum cutting treated by different level of IBA. The experiment was assigned in a completely randomized design on propagation phase and randomized block design on planting phase. The first factor was cultivar which consist of 3 varieties : V1 = Puspita Nusantara, V2 = Fiji, V3 = Dewi Ratih. The second factor was IBA level which consists of 4 levels : D0=0 ppm, D1= 200 ppm, D2= 400 ppm, D3= 600 ppm. The experiment was replicated 4 times. Parameters measured were number of roots, root length, root weight, shoot fresh weight and shoot dry weight. The data were analyzed statistically by analysis of variance and followed by Duncan test. The result showed that number of roots, root length, and root weight were significantly affected by variety treatment and IBA dose treatment. plant height and number of leaves were significantly affected by variety treatment. There was no influence of IBA dose treatment on plant height and number of leaves. Keywords : indole-3-butyric acid, cuttings, chrysanthemum
