Abstract

Based on data from the West Sumatra energy and mineral resources service, it is stated that Limapuluh Kota Regency has the potential for rocks (andesite, granite, limestone, marble) and metallic minerals (gold and lead). This huge natural potential requires good management so that it can develop and requires potential human resources as well. This is the background for socializing opportunities and potential job opportunities in Limapuluh Kota Regency. The socialization explains what potential mining resources exist in Limapuluh Kota Regency along with the job opportunities that exist in managing these resources. The target of this socialization is to open the minds of high school students in terms of the natural potential that their region has and to open up the students' insight in choosing the science they will study in college, so that as sons/daughters of the region they can contribute to the management and development of their region.

Abstract

Composter Engineering. The research method uses the treatment of the number of semi-anaerobic composter oxygen channels with 3 different oxygen holes. The results showed that the lowest temperature was obtained on repetition 1 for composter 6 holes with a temperature of 31.64°C and the highest for repetition 2 on composter 8 holes were 32.85°C. The lowest pH was obtained on repetition 1 for composter 10 holes with a pH of 5.66 and the highest for repetition 3 on composter 6 holes was 6.55. The results of the characteristics of compost fertilizer were obtained from the analysis of time, water content, phosphorus (P2O5), potassium, carbon, nitrogen, and C/N ratio. The conclusion was obtained, a semi-anaerobic composter was produced with 3 types of holes, namely 6 holes, 8 holes, and 10 holes with a composter tube capacity of 60 liters, having dimensions of 40 cm in diameter with a height of 60 cm and for the time the composter obtained the ideal compost was a composter with several holes the most is 10 holes with the results obtained which are 15-16 days compared to 6 holes 28 days and 8 holes 23 days. It is recommended to use materials that are not too wet which will inhibit the rate of decomposition and the presence of a pungent odor.

Abstract

Garbage that is disposed of at the Air Cold Disposal Site (TPA) does get treatment upon arrival there. With the sanitary landfill method, inorganic waste is piled up in each different zone. Meanwhile, the collected organic waste is processed into compost. However, as the population of Padang City increases, the amount of waste also increases. In this case, the cold water TPA itself will gradually run out of capacity. From the results of the analysis of the amount of waste generation carried out, it was found that the average amount of waste generated at the Waste Management Institute (LPS) in Air Tawa Timur Village was 1,815.3 kg/day. While the volume accommodated by the Temporary Disposal Site (TPS) is 6,831 m3
