Abstract

This study aims to determine: 1) the variation of the local buffalo phenotype in East Java from the Banyuwangi and Blitar regions; and 2) genotypes of local buffalo-based genotypes in East Java from the Banyuwangi and Blitar regions. Observation of genetic variation patterns was carried out starting from the stages of DNA isolation followed by electrophoresis using agarose gel after PCR was carried out and followed by polyacrylamide gel electrophoresis. From this gel electrophoresis, a band was obtained which was then analyzed using Genepop ver. 3.1d. The results of the analysis show that the genetic variation of Blitar buffalo population is higher when compared to the Banyuwangi buffalo population. This can be seen from the average value of allele polymorphic information in the Blitar buffalo population of 55% while the average value of polymorphic information in the Banyuwangi buffalo population is 47%. The allele frequency values of the three microsatellite loci of Blitar buffalo population ranged from 0.06 to 0.65, while the allele frequency values of the three microsatellite loci of the Banyuwangi buffalo population ranged from 0.07 to 0.63, after the allele frequency values were known, the analysis continued with determination heterozygosity value. The average value of heterosigosity in the Blitar buffalo population of the three loci is 41.50%, while the average value of heterosigosity of the Banyuwangi buffalo population is the third locus of 27.60%. This figure shows that the average value of heterosigosity in the Blitar buffalo population is higher when compared with the average value of heterozygosity in the Banyuwangi buffalo population.

Abstract

The objectives of this study are as follows: 1) describe the conditions of educational background, biogas knowledge, family economic status, attitude and management of biogas in villages with energy independent titles in Malang Regency, 2) explain the relationship between exogenous variables of educational background, biogas knowledge, and family economic status in the management of biogas in the village with the independent energy title of Malang Regency, 3) explaining the influence of educational background, biogas knowledge, and family economic status on the attitude of the community in the energy independent Malang Regency, 4) explaining the influence of educational background, knowledge biogas, family economic status, and attitudes towards biogas management in villages predicated on energy independence in Malang Regency, and 5) implementing research results in the form of booklets for learning biogas management communities in Malang Regency. The instrument for measuring the educational background of farmers is expressed based on the length of time passed by farmers in taking education. The instrument for measuring biogas knowledge is a test of knowledge about biogas management. The instrument used to measure family economic status is an economy class index based on ownership of valuables. The instrument used to measure attitudes is a test of attitude towards biogas management. The instrument for measuring behavior related to the management of biogas is a matter of observation and structured interviews. Instruments for collecting data first by compiling a grid, which includes empirical indicators, descriptors of empirical indicators, and questions. Causal correlational research results show: 1) educational background, biogas knowledge, and family economic status towards attitudes accepted at a significant level p = 0.007 <0.05, terminated coefficient values R2 = 0.124 can be interpreted as educational background, knowledge of biogas together the same effect on attitudes is 12.4%, meaning that other variables also influence attitudes as much as 87.6% and cannot be explained in this research. Individual education background influences attitudes of 10.1%, while knowledge variables and family economic status individually do not influence attitudes. 2) educational background, biogas knowledge, family economic status, and joint attitudes influence the management of biogas. The terminated coefficient value R2 = 0.175 can be interpreted that the educational background, biogas knowledge, family economic status, and attitude together influence the management of biogas by 17.5%, meaning that other variables also influence the management of biogas by 82.5% and can not be explained in this study. Individual economic status influences the management of biogas by 25.4% and individual attitudes influence the management of biogas by 34.2%. And 3) there is an indirect influence of educational background through attitudes towards biogas management and no indirect influence on biogas knowledge, family economic status through attitudes towards biogas management.
