Abstract

Concious of environment problem in latest decade, to cause many countries to define application lead compound in motor gasolines. The experiment has conducted for evaluation quality of MMT (Methylcyclopentadienyl Manganese Tricarbonyl) additive to compare with TEL (Tetra Ethyl Lead) that is more than 70 years ago to be used. The experimentation has carried out together with technicien team of Ethyl Corporation to be produced MMT meant. The experimental has shown, for in behalf of MMT 9 ~ 36 mgram Mn/litre concentration base on motor gasoline components of 77.3 and 82.5 Research Octane Number (RON), the increase octane number roundabout of 1.7 ~ 4.1 RON. This actane gain lower than TEL with smallish concentration of 0.08 ~ 0.28 mgram Pb/litre, now with standing to be able increase the actane gain roundabout of 2.8 ~ 7.9 RON on the same test samples.

Abstract

This empirical study aims to examine The effect of Net Income, Company’s value, Sales growth and Institutional Ownership on The Dividend Policy of Syariah Stocks and Common stocks listed in BEI in 2013-2015. The sampling method used is purposive sampling amounted to 50 samples that consist of 30 syariah stocks and 20 common stocks. Multiple regression analysis and chow test are used as data analysis method. The results of F test shows that simultaneously, net income, company’s value, sales growth and institutional ownership affect the dividend policy on both syariah and common stocks. However, when tested partially, on syariah stocks, only net income and sales growth that have positive effect on the dividen policy while on common stocks, only net income and company’s value have positive effect on the policy. From the chow test result, it shows that there is a difference between the effect of net income, company’s value, sales growth and institutional ownership on the dividen policy of syariah stocks and common stocks..

Abstract

Mining activities require mechanical equipment and costs to support production targets. Operational costs greatly affect the company's income, so it is necessary to analyze operational costs. This study analyzes the realization of operational costs to determine the causes of losses experienced by the company. The analysis process is carried out by estimating coal getting production to find out the number of tools used, namely 1 unit of digging equipment and 6 units of conveyance equipment with operational costs (fuel, oil usage, filter usage, labor wages, spare parts, grease usage, tire usage) , and equipment rental). The estimated operational costs incurred for the production of coal getting amounted to IDR 762,938,772 while the realization was IDR 302,819,845 using 1 unit of digging equipment and 5 units of transportation equipment. Estimated operational costs for stripping overburden amounted to Rp. 2,728,246,056 using 2 units of digging equipment and 12 units of hauling equipment, while the realization was Rp. 1,327,850,880 using 2 units of digging equipment and 15 units of hauling equipment. Production realization in April 2019 overburden and coal getting stripping was not achieved, this was due to the large duration of rain and slippery time. The percentage of rain duration reaches 6 percent and slippery time reaches 27 percent. The total operational costs incurred for the production of coal getting amounted to IDR 1,630,670,724.50 with a coal price of IDR 450,000 / ton and actual production of 1,106.88 tons so that the revenue from coal sales in April 2019 was IDR 498,096,000. This resulted in the company experiencing a loss of IDR 1,132,574,725. The factors that caused the company to suffer losses were low production due to the many durations of slippery rain, the operational costs incurred were greater than the income from coal sales and the number of tools that stood by reached 24 percent.

Abstract

Pit 3East ElectrificationBanko Barat PT Bukit Asam, tbk has provided mining support equipment of 2 units of Komatsu D375A bulldozer, 4 units of Komatsu D85SS bulldozer, 1 unit of MG825 grader and 1 unit compactor, with rental status. However, the availability of supporting equipment that has been provided can not fully support the April 2018 production target Therefore it is necessary to recalculate the amount of supporting equipment that should be provided in April 2018. After the improvement efforts in the form of additional supporting equipment, the total production capable of producing PC3000E-6 shovel amounted to 729,932 bcm / month, an increase of production amounted to 329,535 bcm / month.The result of calculation of requirement of mine supporting tool based on productivity of each tool can be concluded that the number of tools that should be provided are 2 units of Komatsu D375A bulldozer, 5 bulldozer D85SS units, 3 MG825A grader units and 2 compactor units. Based on calculations made the company issued a rental fee lower than the actual APT rental fee of Rp7.769 / bcm which is Rp 5,919 / bcm, making it more profitable than the previous conditions.

Abstract

Dalam kegiatan penambangan sangatlah berkaitan dengan biaya untuk mendukung target produksi. Biaya operasional sangatlah berpengaruh terhadap keuntungan atau kerugian perusahaan, sehingga perlu adanya analisis terhadap biaya tersebut. Penelitian ini menganalisis biaya operasional bulldozer ripping Komatsu D375 yang memiliki 2 unit Bulldozer pada kegiatan ripping dengan nomor unit DZ265 dan DZ262 yang bertujuan untuk mengetahui keefektifan produksi dari masing masing unit serta biaya operasional pada kegiatan ripping berlangsung. Proses analisis dilakukan dengan melakukan perhitungan terhadap produktivitas dan biaya operasional (bahan bakar, perbaikan, upah tenaga kerja) serta perhitungan terhadap pendapatan hasil ripping overburden. Maka dari hasil analisis tentang produktivitas, biaya operasional dan pendapatan maka unit yang lebih efektif dan efisien yaitu Bulldozer DZ265 dengan produktivtasnya sebesar 1481.04 Bern/Jam sedangkan Bulldozer DZ262 sebesar 1330.43 Bern/Jam faktor yang mempengaruhi perbedaan produktivitas yang eukup signifikan meliputi luas area ripping, pengawasan, keterampilan operator. Serta pada unit Bulldozer Komatsu DZ262 dibandingkan dengan unit Bulldozer DZ265, memiliki tingkat keefektifan yang lebih unggul dilihat dari 4 indikator yaitu 4 indikator yaitu physical availability, mechanical availability, use of availability dan effective utilization. Hal ini disebabkan oleh jam operasi, jam breakdown serta jam maintenance yang eukup berbanding jauh antara kedua unit tersebut pada bulan Maret 2023. Adapun total biaya operasional dari Bulldozer Komatsu D375 sebesar Rpl.266.916.353 dengan total pendapatan bersih yang telah dilakukan pengurangan dari biaya operasional, maka pada bulan Maret 2023 PT Bina Sarana Sukses mendapat keuntungan dari hasil ripping overburden sebesar Rp37.097.695.647
