Isolasi dan Karakterisasi Selulase dari Trichoderma Viride dan Rhizopus Spp dengan Substrat Jerami Padi
The objectives of this study were to isolated and produce cellulase from soil molds and to characterize the enzyme. The strains of mold isolated from soil, namely Rhizopus spp and one cultured mold. Trichoderma viride, was used to produce the enzymes. Medium for enzyme production consisted of NH4NO3, KCl, FeSO4.7H2O, MgSO4.7H2O, CuSO4.2H2O and rice straw as a sole source of carbon (pH : 5.45). Culture was done at 28oC for 5,8,11 and 14 days with shaking at 150 rpm. Using this method cellulase production was optimum at 14 days with substrat concentration of 1.5% for T. viride culture. However the optimum production of cellulase for Rhizopus spp culture were three days shorter than culture of T.viride with substrat concentration of 1.5 and 1% respectively. Temperature and pH optimal activity of cellulases were as follow : cellulase from T.viride at temperature 60oC and pH 5 and cellulase from Rhizopus spp at temperature 50oC and pH 5. While temperature and pH stability of cellulases were as follow : cellulase from T. viride at temperature 30 - 80oC and pH 3 - 7 and cellulase from Rhizopus spp at temperature 30 - 80oC and pH 3-6. It was concluded that molds can grow on rice straw as a sole source of carbon produce cellulases

Crude Nutrient and Mineral Composition of Asystasia Gangetica (L) Derived from Different Growing Areas
Asystasia gangetica as a predominant plant species for feeding goat grows
widely in various lands in Payakumbuh region. The present study was aimed to
determine crude nutrient and mineral composition of the wild plant derived from five
different growing areas, i.e. banana and cacao plantations, road sides, idle lands and
river banks. The sampling sites were distributed in 3 different subdistricts. Fresh
samples which were collected by using a plate meter of 0.5 x 0.5 m2 were weiighed,
chopped, dried and then ground in meal form prior to analysis for dry matter (DM),
crude ash, crude protein (CP), crude fiber (CF), acid detergent fiber (ADF), cellulose,
and minerals of Ca, P, Mg, Cu, Zn, Mn. Data were subjected to analysis of variance
(ANOVA) in completely randomixed design of 5x3 consisting of 5 growing areas
and 3 subdistricts as replications. Results showed that A. gangetica contained
relatively low DM of 9.3-11.9%. Crude ash ranged 16.8-20.9%, CP: 15.5-25.0%, CF:
23.2-28.6 %, ADF: 42.5-46.4%, and cellulose :26.5-29.7%. Macro mineral Ca ranged
18.8-20.5 g, P:11.2-17.4, Mg: 7.5-8.5 g/kg DM. Trace element of Cu ranged 22.0-
29.4 mg, Zn:17.4-22.6 mg, Mn: 36.2-41.4 mg/kg DM. A. gangetica grown in the
banana plantation areas showed the highest crude protein content, while the highest
fiber content was found by A. gangetica collected from the cocoa plantation. A.
gangetica grown in river banks tended to have the higher mineral content of Ca, P,
Mg, and Cu

ABSTRACT
In 2021, the community service team returned to assist the development of the "RegRa Hatchery" business in Lubuk Tarok Sijunjung by providing breed layer ducks from the “ratu duck strain. The partner was really waiting for him because he had built a cage for the breed layer ducks in the service activity in 2020. The efforts made by the community service team to develop the business were by providing assistance in the form of breed layer ducks and some of the ingredients for the duck diet so that in the future, they can produce eggs—own seeds by not bringing in hatching eggs from other places, as was done before. The method used in this service is to provide input and demonstrations in the management of laying ducks, management in mixing and compiling rations according to the ration formulation that has been prepared by the community service team introducing BSF maggot cultivation as an alternative feed ingredient in rations. The result of this service is that partners are very enthusiastic in carrying out all the input and suggestions given by the community service team; partners ask several questions about the management of raising ducks. The conclusion of this service is that partners are able to carry out breed layer duck cultivation with assistance from the community service team.

This experiment aimed to determine the best cellulose sources from the agricultural by product on the production of the thermostable cellulase enzymes by thermophilic bacteria (NG2) and also to find out the best concentration level of the selected sources of cellulose. The experiment was conducted in two stages using a completely randomized design (CRD). In phase 1, four cellulose sources were used, namely A: corn cobs, B: rice straw, C: coconut fiber, and D: oil palm trunk, in which the replication for each source was five. In phase 2, the best sources of cellulose from the phase 1 was used at four different levels of concentration, i.e., A: 2%, B: 3%, C: 4%, and D: 5%, in which replication for each concentration was five. The result of phase 1 showed that the corn cobs was the best cellulose source in producing cellulase enzyme. This was indicated by the activity of 0.329 U/ml, the enzyme protein of 0.0328 mg/ml, and the specific activity of 10.165 U/mg, which were significantly higher (P<0.01) than those of other cellulose sources. The results of phase 2 showed that the concentration of 4% (w/v) had the highest (P<0.01) specific activity of 44.002 U/mg compared with those of the other concentrations. In conclusion, the highest production of cellulase enzyme using thermophilic bacteria (NG2) was obtained at the concentration of 4% (w/v) using the corn cobs as the cellulose source
