Abstract

In order to fulfill food needs, we need another food resources beside rice. Cassava (Manihot esculenta L.)  is one of the sources food that substitutes the rice. Beside that, utilization of ultisols as cropland can support the efforts to fulfill food needs. This study was conducted to determine the effect of giving Phosphate Solubilizing Fungi (PSF) to one variety (Malang 1) and three accesions of cassava (Sutera, Kuning, and Bayel) on planting in ultisol land. The experiment were conducted with a split plot design, where the main plot consists of PSF and non PSF, while the subplot consists of 1 variety and 3 accessions of cassava. The results showed that addition of Phosphate Solubilizing Fungi (PSF) gives good effects to some characters such as plant height, number of leaves, number of tuber, and tuber weight if compared without PSF. Furthermore, only the Kuning accesion that shows the interaction with PSF for the number of leaves character.

Abstract

Utilization of waste chicken feather and crab shells as compost material is an alternative to reduce the environmental pollution caused by waste. This research is identify and study the effect of the addition of crab shells during composting of chicken feather in improving the physical and chemical quality compost chicken feather. The composition compost consists of 1.75 kg of chicken feathers  + 0.15 kg of chicken manure + 0.1 kg bran. Treatmentincludesresearch R0 without the addition of crab shells, R1 0,2 kg, R2 0,4 kg, R3 0.6 kg shell crab. This research used a cluster randomized design (RAK) consisting of 4 treatment, which was repeated 3 and each treatment has 3 samples, 36 samples were obtained observations. Observationsonthe observed variableswere analyzedusing theF test. If there is atreatmentthat have areal effect, it willcontinueto usefurthertestingHonestlySignificant Difference(HSD) with a95% confidence level. Physical parameters include is water conten, temperature, and colour of compost. Parameters  chemical  include is N, P, K, Ca, C-Organik, and C/N ratio. The results showedthat theaddition 0.6kg ofcrabshellsonly givethe effectin improving quality pH (7,29%), Ca (6,8%), P (1,16%), N-Total (4,16%).
