Biogas liquid waste is one of the organic fertilizers that can be used in plants. The benefit of biogas liquid waste is that it can improve soil properties and produce agricultural products that are safe for health. The purpose of this study was to determine the effect of dose and time of bio-slurry fertilizer on the growth of red onion (Allium cepa L.). Research used a randomized block design consisting of two factors. The first factor is the time of fertilizer application which consists of four levels, namely: control, W1, W2 and W3. The second factor is the administration of bio-slurry fertilizer dose of 25 ml, 50 ml, 75 ml and 100 ml. The results showed that the application of bio-slurry fertilizer affected the growth of shallots. The treatment of D4W1 (fertilizer every week with a dose of 100 ml) showed the best results in each parameter, namely plant height, leaf number, leaf area, root length, wet weight and dry weightABSTRAKPeningkatan produksi bawang merah diperlukan adanya perbaikan teknik budidaya  dan pemberian pupuk organik. Limbah cair biogas adalah salah satu pupuk organik yang dapat digunakan pada tanaman. Manfaat limbah cair biogas adalah  dapat memperbaiki sifat-sifat tanah dan menghasilkan produk pertanian yang aman bagi kesehatan. Tujuan dari penelitian ini yaitu untuk mengetahui pengaruh dosis dan waktu pemberian pupuk bio-slurry terhadap pertumbuhan bawang merah (Allium cepa L.) Penelitian menggunakan Rancangan Acak Kelompok yang terdiri dari dua faktor. Faktor pertama yaitu waktu pemberian pupuk yang terdiri dari empat taraf yaitu: kontrol, W1, W2 dan W3. Faktor kedua adalah pemberian dosis pupuk bio-slurry yaitu 25 ml, 50ml, 75 ml dan 100 ml. Hasil penelitian menunjukkan bahwa pemberian pupuk bio-slurry berpengaruh terhadap pertumbuhan bawang merah.

One aspect that needs to be done is to use good quality chrysanthemum seeds. The obstacle of seeds from cuttings propagation is thin roots. Efforts to increase root cuttings are by giving exogenous growth regulating substances to stimulate root formation in propagation shoot cuttings. The objective of this study was to find out the effect of onion skin (Allium cepa L.) on the formation of chrysanthemum (Chrysanthemum sp) cutting roots. The natural growth regulating agent used is red onion skin (Allium cepa L.). The method that used is experimental method with a Completely Randomized Design (CRD) consisting of 6 treatments, 1 treatment as control and 5 treatments as a treatment that is given different concentration namely 60%, 70%, 80%, 90%, and 100% with 5 times retreatment. From the data that has been obtained from the experimental results, data analysis is done using analysis of variance (ANOVA) using Microsoft Excel. If the results show the value is significantly different then it will be followed by BNT 0.05 test. Parameters observed include percentage of growing cutting, root length, number of root and when buds appear. The result showed that onion skin significantly affects the roots formation of chrysanthemum cuttings. The optimal effect of onion skin was shown at 80% concentration on the number of roots and root length with an average number of roots 19 and 3,7 cm root length.
