ABSTRACT:The purposes of this research were to determine the effect of addition of Azotobacter bacterial culture into media of goat faeces on medium quality and earthworm productivity; and also to examine the best dose of Azotobacter bacterial cultures addition. The research material was 800 g earthworm aged 3 months old. The research method was experimental with Completely Randomized Design using 4 treatments and 4 replications. The results show that addition of Azotobacter bacterial culture had a significant effect (P<0.01) on the medium quality and earthworm productivity (coccoon production, the number of juvenils per coccoon, coccoon hatching percentage, the numbers and weight of earthworm). The bacterial culture addition of 350 cc/100 kg goat faeces was found the best. We suggest to follow the study with observation about the effect of the length of fermentation to the medium quality and earthworm productivity.

There were diffferent performance between silkworms breeded in Soppeng and Temanggung. There might be different proportion of parenstock and environment which causing polymorphism. This experiment was to know the genetic band pattern as the effect of the silkworm origin to the genetic characteristics. RFLP method was applied by using restriction enzymes of Pst1 and EcoR1. Based on DNA running by RFLP method using those enzymes, there was no different DNA slice fragment, either between breeding site or genetic polymorphism of each breeding site. This may be caused by the mutation happened in position DNA arrangement which was not recognized by the two enzymes.

The purpose of this study was to find out the sweating rate and anatomy of the sweat glands of Simmental and their crossing with the Ongole cross bred (SimPO) bulls. The research was conducted in Authorized Slaughter House of Gadang, Malang City and the Bioscience Laboratory of University of Brawijaya. The material used were 4 Simmental, and 5 SimPO bulls with an average weight of ≥300 kg and age of ≥2 years. Sweating rate data were collected use Cobalt Chloride Disc. The anatomy of the sweat gland skin samples were observed in the Bioscience Laboratory. Data sweating rate obtained were analyzed statistically using unpaired t-test. The result showed there was significant difference (P<0,05) of sweating rate between Simmental and SimPO bulls. The sweat gland of Simmental have a smaller size and tubular likes shape than SimPO. The SimPO has a large and baggy sweat gland.

This study aims to determine the effect of soybean fermented and pollen paste on the growth of honey bees including larvae length increase, pupae length increase and pupae abdominal diameter increase. The research material is honey bee apis mellifera from farms in Cendoro village, Dawar Blandong sub-district, Mojokerto regency, as many as 96 of honey bees in the form of larvae aged 2 days and 5 day old and pupae 4 day and 11 day old. The research method was experiment / trial with Completely Randomized Design (CRD) consisting of six treatments and four groups. The data were analyzed by analysis of variation (ANOVA) and continued with Duncan Multiple Range Test if there were differences. The results showed that the influence of each treatment on the length of the larvae and pupae was significantly different (P <0.01), while the pupae width variable was not significantly different (P> 0.05). The best treatments that affect the length of the larvae are P0, P1, P4, P5 but the effect is not different from P2. While the best treatment that affect the length of pupae is P3. It was suggested to conduct a similar study but use different types of beans to determine the effect on the worker bee brood.
