The objective of this research are to know the effect of intensively use of pure chicken manure and chicken manure in combination with husk in the Dieng Plateau potato farm, Sembungan Village to structure of soil microarthropods. Sampling was located in two station of potatoes farmland that uses pure chicken manure (chicken manure: CM) and chicken manure in combination with husk (chicken manure + husk :CMS). Soil sampling was applied using transect line method with five sampling points. The structure of soil microarthropods communities was analysed into relative abundance, the Shannon-Wiener’s diversity index, the evenness index, the Sorensen’s similarity index, and Hutcheson’s t-test. The results showed that the density of soil microarthropods on potato farmland using chicken manure in combination with husk (5620 individuals/m2) was higher than farmland using pure chicken manure (1830 individual/m2). The dominant taxa in both farmland are Acari and Collembola. Based on the index of Sorensen similarities, the composition of soil microarthropods in both farmlands is relatively similar (76%). Statistically, the diversity of soil microarthropods between the two different potatoes farmland is significantly different.

Consumption of meat as a source of animal protein has increased every year, especially the consumption of rooster. The increasing cost of poultry feed has made it difficult for breeders to produce roosters that have meat with high protein content. The cost of poultry feed can be minimized by the addition of herbal ingredients, one of which is the addition of leaf powder. Moringa oleifera leaf powder contains various kinds of amino acids and antioxidants that can be used as a supplement to additives feed. This study aimed to evaluate the effect of M. oleifera leaf powder on carcass weight rooster (Gallus gallus domesticus L.). Completely randomized design (CRD) used in this study consisted of 5 treatment groups with three replications, namely the control treatment group and the basal feed treatment group supplemented with Moringa leaf powder 1; 2; 3; and 4%. The feed used is the standard starter and finisher period rations formulated with Moringa leaf powder according to their respective concentrations. Parameters were measured during the seventh week when the rooster was 49 days old, which included: body weight, carcass weight, breast weight, and thigh weight. Based on the research conducted, it was found that giving Moringa leaf powder 1; 2; 3; and 4% as feed additives in rooster had no significant effect (p> 0.05) on body weight, carcass weight, breast weight, and thigh weight. Overall, the conclusion of this study is the addition of Moringa leaf powder with a concentration of 1; 2; 3; and 4% in rooster feed up to 7 weeks of age did not affect on carcass weight, breast weight, and thigh weight of rooster.
