Abstract

The inventory system is one of the most important managerial functions, since vast majority of companies has large investment involved in this aspect. This also applies to PT. Palko Sari Eka that is big in the field of inventory planning and production control. PT. Palko Sari Eka, as one company in the oil refinery industry, strives to optimize the inventory of raw materials Crude Coconut Oil by trying to compare different methods of inventory control methods such as the EOQ (Economic Order Quantity, method of EOI (Economic Order Interval), Min-Max method. Crude Coconut Oil is one of the major raw material products, which require a good inventory system. From the results of research conducted, it turns out the character of stochastic demand data, it is also necessary to conduct simulations to obtain results closer to the actual conditions. The inventory criteria can be said to be optimal if the total annual cost is minimum. It is concluded that the best method is the Fixed Size Order Systems (EOQ) with an order of 2770 mT per order.

Abstract

Penelitian ini dilakukan untuk menguji dan menganalisis pengaruh pengungkapan corporate social responsibility terhadap agresivitas pajak. Selanjutnya, penelitian ini juga menganalisis perbedaan pengungkapan CSR dalam tiga sektor besar (primer, sekunder, dan tersier). Populasi dalam penelitian ini adalah perusahaan yang listing di Bursa Efek Indonesia (BEI) pada tahun 2014-2016 sebanyak 539 perusahaan. Metode sampling yang digunakan adalah purposive sampling, sehingga diperoleh sebanyak 129 sampel. Penelitian ini juga menggunakan data sekunder yang diperoleh dari website BEI. Metode statistik yang digunakan untuk menguji hipotesis penelitian adalah analisis regresi linear berganda dengan bantuan software SPSS 21.0. Hasil penelitian ini membuktikan bahwa pengungkapan corporate social responsibility tidak berpengaruh terhadap agresivitas pajak. Kemudian dari hasil Uji T, ternyata sektor primer lebih luas mengungkapkan tanggung jawab sosialnya dibandingkan pada sektor sekunder dan tersier.

Abstract

Hydrothermal liquefaction (HTL) of oil palm empty fruit bunch (OPEFB) in different organic solvents (methanol, ethanol, acetone, toluene and hexane) to produce bio-oil were comparatively investigated. Experiments were carried out in an autoclave at different temperature of 300, 350 and 400 oC with a fixed solid/liquid ratio of 4 gram in 50 mL solvent, without catalysts and reaction time of 5 hours. The liquid products were analyzed using GCMS to determine the chemical composition. Result showed that the chemical compositions were greatly affected by the solvent types. Each solvent has a major component in bio-oil products. The major compounds resulted from methanol and ethanol solvent were ketones/others. The major compounds resulted from toluene and hexane solvents were organic acid, which favoured high temperature. Meanwhile, esters and organic acid were the major products from acetone solvents. Temperature operation resulted more variations in the chemical composition and the percentages of the bio-oil.

Abstract

Maton House housing has a local fiber access network that uses a duct system and the device feeder are inefficiency. This papper purpose to analyzes the FTTH network at Maton House-Pekanbaru Housing to improve the efficiency of optical transmission, using several parameters such as: power budget link, rise time budget, and optical power. The analysis process is done with some supporting software such as: Optisystem, AutoCad, and Google Earth. Calculation of Optical Power analysis parameters performed by simulation using Optisystem software found the average value of loss is 21.11 and the measurement using Opical Power Meter found the average loss value is 22.50 dBm. According to the acquisition of large optical power on optical transmission in Maton House housing proves the network is much smaller of damping than the standard total that is below -28 dBm based on IEEE at 802.8 .Keywords: FTTH, link power budget, rise time budget, optical power.
