Bio-SRF is a biofertilizer formulation containing a mixture of several types of microbes improving soil fertility. The aims of this study were to assess the production process of Bio-SRF biofertilizer and to identify its effectivity on Keywords: Biofertilizer, Bio-SRF, production process, effectivity test, shallot plant ABSTRAKBio-SRF merupakan formula produk pupuk hayati yang mengandung campuran beberapa jenis mikroba penyubur tanah. Penelitian ini bertujuan untuk mengkaji proses produksi pupuk hayati Bio-SRF dan mengetahui efektivitasnya terhadap pertumbuhan dan produktivitas tanaman bawang merah. Kajian produksi pupuk hayati Bio-SRF meliputi perbanyakan biomassa sel mikroba, granulasi dan formulasi produk. Hasil penelitian menunjukkan bahwa populasi sel pada produk pupuk hayati Bio-SRF bentuk granul adalah Corynebacterium sp. 4 10 7 cfu/g, Lactobacillus sp. 3,8 10 7 cfu/g, Burkholderia seminalis 7,4 10 8 cfu/g, Pseudomonas stutzeri 4,5 10 8 cfu/g dan mikoriza 60 spora/g produk. Hasil uji efektivitas menunjukkan bahwa perlakuan pupuk hayati berpengaruh nyata terhadap tinggi tanaman, jumlah umbi, bobot basah dan bobot kering umbi bawang merah yang dihasilkan. Aplikasi pupuk hayati Bio-SRF pada tanaman bawang merah memberikan hasil terbaik yaitu dengan tinggi tanaman saat panen 34,80 cm, jumlah umbi per tanaman 4,78 umbi, berat basah umbi 3,81 kg/m 2 , berat kering umbi 3,27 kg/m 2 dan dapat meningkatkan hasil produksi bawang merah sebesar 55,71% dibandingkan dengan tanpa aplikasi pupuk hayati.Kata kunci: Pupuk hayati, Bio-SRF, proses produksi, uji efektivitas, bawang merah
The study aims to determine the effect of applying for intercropping food crops (rice, corn, and soybeans = jagole) on the cropping index and income of urban farming community activists. This study was conducted by comparing the use of six models of growing food crops, namely three kinds of monoculture model of jagole, upland rice-soybean, sweet corn-soybean, and sweet corn-upland rice polyculture/ “Turiman”. Observational data includes data on land characteristics, annual cropping patterns in related locations, and input-output data of the test models. Corn and soybeans are harvested young. Data were processed using descriptive analysis and the economic feasibility analysis of the tested technology was based on the R/C ratio. Based on data, it is known that there is potential to increase the cropping index of dry or limited land in the Jakarta area, from 1-2 to 2-3 a year by optimizing planting through intercropping systems/ food crop Turiman. such as corn-upland rice-soybean. The results of the analysis showed that the soybean monoculture technology model, with yields of young soybeans, gave a higher profit (R/C 2.58), compared to the other models, namely sweet corn monoculture, upland rice monoculture, upland rice-sweet corn polyculture, soybean-sweet corn polyculture, soybean-upland rice polyculture, and (R/C respectively: 0.24, 0.54, 0.17, 1.25, and 1.71).
Activities of Stenotrophomonas rhizophila and Trichoderma sp. in Inhibiting the Growth of Ganoderma boninense ABSTRACTBasal stem rot (BSR) disease in oil palm (Elaeis guineensis Jacq.) due to infection of Ganoderma boninense. Various efforts to overcome BSR disease has been done, such as by utilizing endophytic microbes. The purpose of this research was to determine the activities of Stenotrophomonas rhizophila and Trichoderma sp inhibiting the growth of G. boninense. This research was divided into three stages, namely: stability test of S. rhizophila activity against G. boninense; activity of chitinase and cellulase enzymes produced by S. rhizophila; the effectiveness of S. rhizophila and Trichoderma sp. on G. boninense in a greenhouse. The parameters observed were plant height, leaves number, chlorophyll content, disease incidence and severity. The stability testing of S. rhizophila activity against G. boninense showed 53% of inhibition. Chitinase activity showed negative result. While cellulase index was about 0.46. The effectiveness test showed the significantly different results on plant height, leaves number and chlorophyll content.Keywords: Chitinase, cellulase, Ganoderma boninense, Stenotrophomonas rhizophila, Trichoderma sp. ABSTRAKPenyakit busuk pangkal batang (BPB) pada tanaman kelapa sawit (Elaeis guineensis Jacq.) muncul karena diinfeksi oleh Ganoderma boninense. Berbagai upaya penanggulangan penyakit BPB telah dilakukan, diantaranya dengan memanfaatkan mikroba endofit. Tujuan dari penelitian ini adalah untuk mengetahui aktivitas bakteri Stenotrophomonas rhizophila dan Trichoderma sp. dalam menghambat pertumbuhan G. boninense. Penelitian ini dibagi menjadi tiga tahapan, yaitu: pengujian stabilitas aktivitas S. rhizophila terhadap G. boninense; pengujian aktivitas enzim kitinase dan selulase yang dihasilkan oleh S. rhizophila; pengujian efektivitas S. rhizophila dan Trichoderma sp. terhadap G. boninense di rumah kaca. Parameter yang diamati pada pengujian efektivitas berupa tinggi tanaman, jumlah daun, jumlah klorofil, kejadian dan keparahan penyakit. Uji stabilitas aktivitas S. rhizophila terhadap G. boninense menunjukkan adanya penghambatan rata-rata sebesar 53%. Uji aktivitas enzim kitinase pada bakteri S. rhizophila menunjukkan hasil negatif. Sedangkan indeks enzim selulase pada bakteri S. rhizophila sebesar 0.46. Pada uji efektivitas tampak hasil yang berbeda nyata pada parameter tinggi tanaman, jumlah daun dan kandungan klorofil.Kata Kunci: Kitinase, selulase, Ganoderma boninense, Stenotrophomonas rhizophila, Trichoderma sp.
