Full text linkPhytobiotics are derivated from the plants which contains active compounds. They produce antibacterial and antioxidants activity and can improve the condition of the digestive tract. Papaya leaf extracts and mint leaf extracts have the potential as natural phytobiotics because they have antibacterial, antioxidant properties, can improve alimentary tract conditions and increase the absorption of nutrients in the feed. The aim of this study was to compare the utilization of papaya leaf extract (EDP) and mint leaf extract (EDM) in feed on the production and quality of quail egg. A hundried and fourty quails of 42 days age were arranged in a completely randomized design with 5 treatments and 4 replicates (7 quails per replicate). The treatment diets consisted of P0 = Basal diet only (Control), P1 = Basal diet + 100 ppm EDP, P2 = Basal diet + 200 ppm EDP, P3 = Basal diet + 100 ppm EDM and P4 = Basal diet + 200 ppm EDM. The results approved that mint leaf extract reduces in feed consumption, increase egg production and mass and reduce feed conversion values, in contrast the papaya leaf extract produce non-significant on those variables. However, papaya leaf extract was able to increase more white index values and haugh unit of quail egg, while mint leaf extract increased more yolk index values. The addition of 100 ppm mint leaf extract resulted in the highest value of egg production and egg mass. Therefore, the perfomance and quality of eggs in mint leaf group were better than papaya leaf group

Full text linkCentral Sulawesi's 2018 earthquake, liquefaction, and tsunami caused liquefaction in Palu City's Balaroa and Petobo neighbourhoods. Land surface changes affected agricultural land area and soil fertility, which can affect farmers' income. Soil fertility indicates its nutrient-providing capacity. This study aims to assess agricultural land fertility, farmer income, and the best ways to recover from natural disasters. This descriptive study included all Petobo farmers affected by the earthquake and liquefaction. Purposive sampling tested 25 respondents. The field survey collected soil samples at coordinate points. Twelve soil samples were taken from six points at 20 cm and 40 cm depths. The samples were analysed at Tadulako University's Environmental and Natural Resources Analysis Laboratory. The results showed that Petobo Village's liquefaction-affected and unaffected areas had low fertility due to low C-organic and Potassium content, which prevented plants from using soil nutrients. Low soil fertility reduces crop production. Farmers earn an average of Rp. 1,422,857 per hectare, up to Rp. 4,633,929 per season per hectare. To increase soil fertility, farmers can use compost, manure, crop residues like legume plant stover, rice straw, and chemical fertilisers according to dosage
