This research is motivated by the problem of low learning result of mathematics of Pariaman high school students. Based on the observation and documentation, several factors that cause the low quality of professional teachers in teaching, student self-concept of the basics, low learning interest, and the initial ability of students who have not been awakened properly. The purpose of this study is to analyze the direct and indirect influence of each exogenous variable on endogen and analyze the effect simultaneously between variables.Thetype of this research is Path Analysis research, the research population is all students of SMA Pariaman amounting 4,160 people. The sample was taken using stratified proportional random sampling technique so that the number of samples taken was 100 people. Instruments used to retrieve data are questionnaires and documentation. Data were analyzed using SPSS version 16 analysis.
The vast utilization of wetland and dry land in the lowlands of West Sumatra Province for the development of shallots as a potential commodity in an effort to increase farmer income. Shallot is one of the leading vegetables coomodities since it has been cultivated by the people of West Sumatra in the highlands area. The availability of superior varieties of shallots produced by the Agency of Agricultural Research and Development provides many choices in shallot farming, it is necessary to test the adaptation of these superior varieties in the lowlands area. The study aimed to determine the level of adaptation of several shallot varieties in the lowlands area in Pesisir Selatan Districts, West Sumatra. The study was conducted on farmer group land in the Surantih area, Sutera sub District, Pesisir Selatan Districts from April until July 2016. The study used a Randomized Block Design (RBD) with the treatment of four superior shallot varieties namely: Katumi, Bima Brebes, Pikatan and Mentes, with 6 (six) replications. The data obtained were analyzed using variance and continued with the Duncan Multiple Range Test (DMRT). The results of research showed that: (1) the Katumi variety showed a higher harvest weight (14.00 tons/hectare) followed by the Bima Brebes, Pikatan and Mentes varieties, (2) For the Pesisir lowland dry land area, the most adaptive shallot variety was Katumi.
Silokek village is rich in potential who are at Sijunjung Regency, West Sumatra Province. This area, known as the MUSIDUGA (Muaro Silokek & Durian Gadang), has the natural resources in the form of the river which flows between steep limestone hills and beautiful, so that the area proposed to become one of geopark. Problems are found namely the limitations of the community in the management of potential of Natural Resources Company Silokek Village. Yet its optimal strength/ability society (hope/the local wisdom, yet high in the management of community spirit). In this research, the author discusses about how to build a strategy management and maintenance potential of silokek village – based on local wisdom. As for the method does is SWOT, internally and externally. On strategic Management, divided into: Actuating (A), Planning (P), Organization (O), Controling (C). At the end of the study, obtained by the method of development potential Silokek Village based on local wisdom with the concept of sustainable development (Ecologic, Social Culture & Economic) with goals “sustainability” through improved skills human resources and Maintenance Management Strategic (MMS).
This study aims to determine the percentage of buffalo oocytes matured in TCM-199 medium supplemented bovine serum pesisir estrus phase in vitro. Furthermore, to improve the efficiency of in vitro embryo production in buffalo cattle with bovine serum pesisir supplementation estrus phase.Buffalo oocytes matured in TCM-199 medium in 5% CO2 incubator and each treatment was added bovine serum pesisir estrus phase with different concentrations (0%, 10% and 20%).Parameters observed in this study is the percentage of buffalo oocytes matured without the addition of bovine serum pesisir estrus phase, the percentage of mature oocytes by the addition of bovine serum pesisir estrus phase 10% and the percentage of buffalo oocytes were matured by the addition of bovine serum pesisir estrus phase 20% are in vitro.Percentage of buffalo oocytes matured with the addition of bovine serum pesisir phase estrus as much 20% showed a highly significant difference (P <0.01) which is 70.04% when compared with the maturation by the addition of 10% bovine serum pesisir is 56.00% and without bovine serum pesisir estrus phase is 36.96% are in Virto.Based on the results of this study concluded that supplementation with bovine serum pesisir phase concentration of 20% in the maturation medium TCM-199 significantly (P <0.01) in increasing the level of maturation of buffalo oocytes in vitro compared with the addition of bovine serum pesisir estrus phase and without the addition of 10% bovine serum pesisir (control).
