Abstract

Abtract: Industry efficiency can be investigated using a non parametic the method Data Envelopment Analysis (DEA). The research will focus on existing industries in West Sumatra. Secondary data from 12 industries active in West Sumatra West Sumatra is KLUI 15, 17, 18, 19, 20, 22, 24, 25, 26, 28, 34, and 36 from 2007 to 2008. Expenditure of labor, raw materials, fuel and cost of electricity and gas will affect the value of the output will show the efficiency of the industry. The results of this study showed that by using a variable input is labor expenses together, the results of the efficiency is still relatively low. However, by using two input variables, namely expenditure of labor and raw materials, the scores have improved efficiency when compared to using only one input variable. However if the input variable changed to expenditure of labor and raw materials, the efficiency scores also improved when compared to the use of labor inputs and raw materials. Keywords: efficiency, non parametic, Data Envelopment Analysis, industryAbstrak: Efisiensi industri dapat dianalisis dengan pendekatan non parametic menggunakan metode data envelopment analysis (DEA). Penelitian ini akan berfokus pada industri yang ada di Sumatera Barat. Data sekunder dari 12 industri aktif di Sumatera Barat di Sumatera Barat yaitu KLUI 15, 17, 18, 19, 20, 22, 24, 25, 26, 28, 34, dan 36 dari tahun 2007 sampai dengan tahun 2008. Pengeluaran tenaga kerja, bahan baku, dan biaya bahan bakar listrik dan gas akan mempengaruhi nilai output yang akan memperlihatkan efisiensi industri tersebut. Hasil penelitian ini memperlihatkan bahwa dengan menggunakan satu variabel input yaitu pengeluaran tenaga kerja sama, maka hasil efisiensi masih tergolong sangat rendah. Namun dengan menggunakan 2 variabel input yaitu pengeluaran tenaga kerja dan bahan baku, maka skor efisiensi lebih membaik apabila dibandingkan dengan hanya dengan menggunakan satu variabel input. Sedangkan apabila variabel input diganti menjadi pengeluaran tenaga kerja dan bahan baku, maka skor efisiensi juga lebih membaik bila dibandingkan dengan menggunakan input tenaga kerja dan bahan baku.

Abstract

The issue of efficiency of education is increasingly important in the context of Indonesia’s decentralization implemented to the big bang approach. Padang city has a strong commitment to educational development. This study aimed to measure the efficiency of education in 35 Junior High School in the city of Padang in the academic year 2009/2010. This study also aims to determine the effects of socioeconomic status and economics student urban-rural location. The method used is Data Envelopment Analysis (DEA) and a Different Test. The efficiency rate of school on average 93,31 percent was found. Subsequent findings that the school has a student-classroom ratio smaller have a higher level of efficiency. Schools efficiency characterized also by student-classroom ratio is small anyway. Different test result showed that schools with an average student socioeconomic status have a higher average level of efficiency higher than schools with lower socioeconomic status. School located in the city has an average efficiency level higher than rural schools.

Abstract

Sustainable economic development requires people who are able and empowered to meet their needs and escape from poverty. It can be seen that the HDI for women is always below the HDI for men every year. This study aims to identify women's empowerment in the economy and politics can improve women's development in West Sumatra. With the Panel Least Squares (PLS) method then proceed with the classical assumption test, with a panel regression model. Research on 19 districts/cities in West Sumatra with a span of 5 years. The results showed that female professional staff, women's income contribution had a positive and significant effect on women's development, women entrepreneurs had a negative and insignificant effect on women's development, women in parliament had a positive and insignificant effect on women's development in West Sumatra. It can be concluded that women's empowerment in the economy and politics is very important for the development of a country. From the results of this study it is suggested to the government to pay more attention to women's empowerment so as to achieve women's development and improve gender-equitable welfare

Abstract

PT Sumbar Calcium Pratama as one of the mining companies that produces calcium material for core and shell separators for the palm oil mill industry, participates by increasing production to meet consumer needs. PT Sumbar Calcium Pratama is one of the mining companies engaged in the mining of class C excavation material (limestone) whose mining operations are carried out by means of Quarry. The results of taking slope geometry data at PT Sumbar Calsium Pratama obtained a slope height of 30 m with a slope angle of 83 °. The Spencer Slice Method was developed by Spencer in 1967. It is one of the most theoretically rigorous wedge methods because it fulfills the balance of forces and moments of the collapsing mass. Thus, it allows for a more precise calculation of the Factor of Safety (FS). The results of the Rock Mass Rating (RMR) analysis of the rock show that the Rock Quality Designation (RQD) of the rock mass of the slope in the pit 1 mining area of PT Sumbar Calsium Pratama has a slope of 2.58%, and the weight of the Rock Mass Rating (RMR) of the slope belongs to class III (medium). Kinematic analysis then obtained the potential for landslides that will occur in the research area in the form of plane avalanches (Planar Failure) of 10%, wedge avalanches (Wedge Failure) of 9.47%, avalanches (Flexural toppling) of 45%. Recommendations in an effort to increase the stability of the research slope of PT Sumbar Calsium Pratama which is in a saturated state is not stable / safe, first by changing the slope geometry in the form of slope height which was originally 30 meters to 24 m or 23 m then obtained FK values of 1.33 and 1.37 (safe / stable). Second, by reducing the slope from 83° to 65° and 64°, FK values of 1.3 and 1.38 (safe/stable) were obtained.
