Abstract

PT.Bakapindo is engaged in dolomite mining. The mining method applied is the Open Pit quarry method. Currently the mining process is carried out by PT. Bakapindo applies the blasting method to release dolomite rock from its parent rock. In determining the right method for dismantling material, it is necessary to study rock capability. In this study, the method applied to determine the suitable excavation method is by Franklin's rock strength index criteria chart. The data used in the study are discontinuity field conditions taken with the scanline system and rock samples used to test rock strength by means of Point Load Index. Total data on discontinuity field conditions measured in rock mass is 201 data. The results of the point load index test obtained the Franklin (Is) average index value of 4.740MPa. Based on the results of the analysis of rock mass conditions at PT. Bakapindo found that rock mass rating (RMR) of 67 was classified as class II (Good rock), the fracture index value was 0.091m. Based on Franklin's rock strength index criteria graph, it can be concluded that suitable excavation methods are carried out at PT. Bakapindo is byblasting cracks.Keywords: mining method, Index Franklin, rock mass rating (RMR) , Discontinuiy, Point Load Index

Abstract

One of the purposes of vocational school (SMK) is as an education facility to prepare alumni who are ready to enter work field, but in contrary the highest number of unemployed in West Sumatra is dominated by SMK alumni. This research aims to describe the contribution of adversity quotient, self awareness and demographic factors to student career maturity. The study was conducted using quantitative descriptive methods. The research population were students of class XII at SMKN6 Padang as many as 392 students and a sample of research were 198 students. The technique used in this research waspurposive sampling technique. The instrument used was a adversity quotient, self awareness and career maturity scale was using Likert model, and the research data was analyzed using simple regression and multiple regression with dummy variables. The research findings prove that: (1) adversity quotient has an effective contribution of 23% to student career maturity, (2) self awareness contributing as much as 37.9% to career maturity, (3) gender does not contribute to career maturity,(4) socioeconomic status contributes 4.9% to student career maturity, and (6) there were 47.8% of contributions together with adversity quotient, self awareness, gender and socioeconomic status on students' career maturity. This result show that student’s career maturity was not influenced by one variable only but adversity quotient, self awareness and demographic factor all together contribute in forming student’s career maturity. Therefore, increase in career maturity as an attempt to prepare students prior to entering work field could be done by optimizing adversity quotient level and self awareness while also considering demographic factor of each students.

This type of research is a qualitative descriptive study. There are variable models of Donald Van Metter and Carl Van Horn, standard; destination; and policy objectives, resources, characteristics of implementing organizations, implementers' attitudes, communication between organizations, socio-economic and political environments. PT. SAL and PT. Shogun Judging from the six variables in the Donald Van Metter and Carl Van Horn models in the implementation of road infrastructure development in the South Tabir District has been successfully carried out.

Abstract

In Padang there are many traditional markets, but not all markets have permission to slaughter poultry in the market because there are still many markets that do not meet the requirements. In the traditional markets of Padang city that meet the terms and conditions for slaughtering poultry, one of them is the Padang fair market. Apart from that market, there are also those who are not allowed to slaughter poultry in the market. However, currently there are still many cuts being carried out in traditional markets in Padang, including Mr Taufik's cuts in the Padang Raya market. Based on the results of field observations that I carry out with workers every day, these cuts can be prepared. chickens that are ready to sell are 70 kw. So, because of the differences, researchers want to understand the supply chain in depth, the differences between cuts that are permitted and cuts that are not permitted. The author's consideration for choosing a qualitative approach is because the qualitative approach is carried out in natural conditions, or focuses directly on the data source so that in-depth information and more valid data will be obtained in accordance with the research background and field conditions. Based on this research, the population is not greater than 100 respondents, so the author took 100% of the population at Pasar Raya Padang, namely 12 respondents. The implementation of halal supply chains for chicken traders at Pasar Raya Padang has shown a strong commitment to fulfilling halal standards in the supply chain. These chicken traders have taken important steps in ensuring the halalness of their products, starting from selecting trusted suppliers to strict quality control practices. Chicken traders have paid attention to various important aspects in the halal supply chain, including selecting trusted suppliers, appropriate slaughtering processes with Islamic principles, separation of halal and non-halal products, as well as maintenance of cleanliness and sanitation at every stage of the production, storage, transportation and sales processes. challenges faced by chicken traders, such as high costs to obtain halal certification, lack of attention on the halalness of chicken feed, and the need for updates in halal supply chain management practices. Traders need to pay more attention to the halalness of the chicken feed ingredients used to ensure that the entire production process meets halal standards. Chicken traders need to maintain the quality of the chicken meat they sell and provide understanding to consumers to pay attention to the quality of the chicken meat they buy. Traders should consider obtaining halal certification as a step to increase consumer confidence and the sustainability of their business. Traders can take additional steps to increase transparency and accountability in the halal supply chain, such as by increasing the use of technology and information systems.
