Abstract

ABSTRACT: White oyster mushroom cultivated by the community so that the demand for oyster mushroom growing. White oyster mushroom production in Indonesia is still lacking, it is caused by lack of optimal cultivation of oyster mushroom so it can not meet the public demand for oyster mushroom. This study aims to determine "the influence of the quantity of lime to the oyster mushroom mycelium growing pace as the undertakings posters". The research is a qualitative research experiment arranged in a completely randomized design (CRD), with control PI (lime0%), PII (lime 2%), PIII (lime 4%),respectively treatment repeated 10 times to obtain 30 baglog trial. The test results showed that treatment of three (PIII) with the provision of limestone (CaCO3) 4% provide optimal results and significant form of speed of growth of mycelium average (PI) 6.3, (PII) 7.2 and (PIII) 7.6 total average is 7.0 , From the results of this research are made in the form of posters. Poster validation results in the field of education. 84.70% with a decent category and language fields gori 87.05% with a decent word. Thus poster made of the results of this research deserves to be used for the community.

Abstract

ABSTRACT: Kerwa Nature Park (TWA) Kerandangan is one of the tropical forest area on the island of Lombok and has been designated as a conservation area since June 1, 1992. As a conservation area TWA Kerandangan has a high diversity of insect species. The diversity of these insects can be used as bioindicator of environmental stability in TWA Kerandangan. This study aims to identify soil insects, as well as to know the diversity of insects in the TWA Kerandangan area. This research was conducted at TWA Kerandangan and insect identification was done at Biology Laboratory of FPMIPA IKIP Mataram in June 2016. This research was conducted by using Pitfall trap technique in two different location that is on flat land and bumpy land and at two time different in the morning and evening. Result of research on TWA Kerandangan obtained 5 species of insects namely Empoasca fabae, Camponotus modoc, Myrmecocystus mexicanus, Asemoplus montanus and Gryllus spyang total of 124 individuals. The values of the diversity index (H ') for the Empoasca fabaeyaitu species were 0.038, Camponotus modoc0,161, Myrmecocystus mexicanus0,213, Asemoplus montanus0,066 and Gryllus sp 0.175. The highest diversity index value is found in Myrmecocystus mexicanus species and the lowest diversity index value is found in Empoasca fabae species.

Abstract

ABSTRACT: The purpose of this research is to comparing effectiveness of cattle urine as a organic manure on the vegetative growth of green beans (Vigna radiata) and attemp to design a brochure for the people. Research design used in this research is complete random design (CDR). The data collected in this research were obtained using observation and documentation techniques, than that the datum analyzed with one way anova. The sample consit of 4 tratments with the same dosage that is 40 ml/kg of soil and each tratements repeated 6 times. The parameters observed I this research is the plant height, stem diameter, number of leaves, fresh weight, and dry weight. The result of the research on plant height, number of leaves, fres and dry weight of plants showed significant value, while the paramaters of stem diamter showed no significant result. Based on the result of the research show that P1 (treatment using rabbit urine) showed the best result among the parameters plant heigh and the number of leaves.In P2 (treatment using goat urine) giving the best result on the fres and dry weight paramaters of green bean plant. From observation of the fifth parameters, there are four parameters show that rsignificant result, that is plant heigh, number of leaves, fresh and dry weight of green bean, but there are one paramater that has no significant result (no effect), that is stem diameter of green bean.

Abstract

The purpose of this research is to know the characteristic 'water quality' river ancar Mataram city based on biological, chemical, and physics as bioremidiasi waters. The type of this research is descriptive explorative and research method used is survey, laboratory analysis, and case study, ie method of all aspects must be observed fully, while the data analysis is only valid for certain place and time period. The results showed that, overall observation and identification of 6 research sampling stations, 21 species were identified with four microlagae classes: Bacillariophyceae, Cyanopyceae, Chlorophyceae and Crysophyceae. Bacillariophyceae class is the class that has the most types, then Cyanophyceae, Chlorophyceae and Chrisophyceae. Factors supporting the growth of bologic components such as pH, temperature, light intensity, salinity with the range of each 7.2-8.3; 25-27 ° C; 1011-1800 lux; 3-3.2%, nutrients (N and P), according to the microalgae living conditions which are the most primitive plant organisms that are small in size, live in all waters, both rivers and seawater.
