Abstract

Ketercapaian produksi merupakan salah satu indikator keberhasilan kegiatan operasional penambangan. Pemenuhan indikator ini umumnya disebabkan faktor-faktor operasional peralatan tambang, khususnya pada alat gali dan alat muat. Salah satu faktor ini adalah kesediaan alat tambang, yang didalamnya terdiri dari ketersediaan fisik (PA), ketersediaan mekanis (MA), dan efektif pemakaian (EU). Rendahnya nilai parameter umumnya berdampak pada ketidaktercapaian target produksi. Pada penelitian ini menggunakan metode evaluasi kuantitatif, dimana dilakukan evaluasi pada jumlah kebutuhan alat yang digunakan untuk mencapai target produksi overburden, data yang dibutuhkan pada penelitian, waktu siklus dari alat muat dan angkut. Dilakukan simulasi pada waktu standby alat untuk mengoptimalisasikan hasil produksi dari alat yang digunakan. Perhitungan terhadap produktivitas dan produksi tercapai dilakukan pada skenario sebelum dan setelah peningkatan kinerja. Sebagai indikator keberhasilan, faktor keserasian (MF) juga dihitung pada kedua skenario. Pada akhir studi, dilakukan perhitungan kebutuhan peralatan untuk melihat pengaruh peningkatan kinerja pada kebutuhan peralatan tambang. Setelah dilakukan pengolahan data yang didapat dapat kesimpulan bahwa optimalisasi waktu standby alat tidak cukup untuk mencapai target produksi overburden, dan dibutuhkan satu unit tambahan pada alat angkut.

Abstract

This research aims to determine the influence of compensation and organizational culture on employee performance at PT. Yamaha Thamrin Brothers Manna-Kaur. This type of research uses quantitative descriptive research methods. The population used in this research were employees from PT. Yamaha Thamrin Brothers Manna-Kaur. The number of respondents in this study was 50 people. The data collection method uses a questionnaire and uses analysis techniques using multiple linear regression analysis tests and hypothesis testing, namely the t test and f test. Based on the results of multiple linear regression, the regression equation form Y = 2.224 + 0.531 X1 + 0.497 (2.192> 1.677) and (sig α = 0.001 < 0.005). This means H_0 is rejected and H_a is accepted. Organizational culture has a positive and significant effect on employee performance, this is proven by the results of the t test showing the value of tcount > ttable (2.097 > 1.677) and (sig α = 0.001 < 0.005). This means H_0 is rejected and H_a is accepted. Compensation (X1) and Organizational Culture (X2) together have a significant effect on Employee Performance (Y) at PT. Yamaha Thamrin Brothers Manna- Kaur, this is proven by the F test showing the value of fcount > ftable, namely 11.254 > 3.19 and (sig α = 0.000 < 0.005). This means H_0 is rejected and H_a is accepted.

Abstract

The production process with the green synthesis method is a method that is being developed in the production process for daily household needs. One of the green synthesis methods that has been developed is using waste products such as waste cooking oil (WCO) as a raw material in the soap production process. In the process of making soap, saponification reactions occur between triglycerides and fats and oils that occur in alkaline solutions. The materials used are a mixture of WCO, distilled water, and sodium hydroxide. The WCO used in this training is purified WCO with the addition of natural zeolite. Acid-activated natural zeolite, to increase its catalytic ability, is used as an adsorbent to adsorb impurities contained in WCO. The training consists of three stages: providing material about the dangers and negative effects that can be caused by using used cooking oil in everyday life for both the environment and health, the WCO cleaning process, and the utilization of purified WCO into an efficient product in the form of laundry soap. The results of the activities carried out can be seen from the discussion activities carried out after the activity took place with the partner community, which show an increase in community knowledge about how to treat waste and the potential for improving the economic situation of the community through knowledge of the soap-making process.
