Abstract

PT. Sarana Agung Sejahtera is a company that sold AC sparepart and AC service. This company wish to develop a new system, because had a difficulty in dealing with administrative issues because its operation is still manual, e.g. the sale and purchase transactions, preparing reports and other expenditures problem. Thus allow for errors in the calculation of sales and purchases and this can be troublesome if carried every day.Based on the problem faced by PT. Sarana Agung Sejahtera, application is made to support them. The application can process purchasing, sales order, selling, stock opname, debit and credit payment. To design the DFD of the new applications Microsoft Visio was used, and ERD application use Power Designer 15.3. This application was made using Code Igniter Framework and PostgreSQL as the database storage.The result of the application showed that this application can take notes of purchasing transactions and sales can be done according to the structure and computerize and also complemented with stock card using First In First Out (FIFO) method. Otherwise, with this application, owner can know some reports, e.g. stock card, general journal, purchasing journal, sales journal, stock position report, service report, employees report, customer reminder report, balance sheet, and income statement. This program help the transaction process with backdate feature which allows owner insert the transactions from the past time.

Abstract

PT. X is a company engaged in manufacturing media printing and paper packaging. PT. X has a fixed product that is a Diknas book. The research is focused on the delivery of Diknas book for East Java region with a total time as the main constrain in determining the route which resulted in the minimum delivery cost of Diknas book by taking into account the capacity of the fleet used. The method used in determining the route with the optimal shipping cost is by the Greedy Algorithm method. Research shows that in zone 1 there are 4 shipping routes with range of shipping cost between Rp100,00/kg-Rp200,00/kg by using joint route, zone 2 there are 3 delivery routes with range of shipping cost between Rp190,00/kg-Rp205,00/kg, zone 3 there are 3 shipping routes with a range of shipping costs between Rp130,00/kg-Rp525,00/kg, zone 2 and zone 3 using separate route method and joint route.

Abstract

Pensiun merupakan salah satu momok yang menakutkan bagi para individu dewasa madya, apalagi bila individu tersebut sedang berada di puncak karirnya. Ketakutan akan pensiun tersebut menimbulkan kecemasan. Mengatasi kecemasan dapat berbeda tergantung pada kemampuan untuk mengatasi kecemasan tersebut (Cheung & Sun dalam Pajares, 2006) dan ditingkatkan melalui kemampuan dan kompetensinya untuk melakukan sebuah tugas, mencapai tujuan, atau mengatasi hambatan yang kuat yang disebut self efficacy. (Bandura dalam Baron & Byrne, 2004). Penelitian ini merupakan penelitian yang bersifat korelasional yang bertujuan untuk mengetahui hubungan antara self efficacy dengan kecemasan menghadapi pensiun pada pengawai negeri sipil. Adapun sampel dari penelitian ini adalah 87 orang yang akan menjelang pensiun hingga akhir tahun 2013 pada kementrian X. Penelitian ini merupakan penelitian kuantitatif dengan dua buah skala sebagai alat ukur, yaitu skala Self Effi cacy dan skala Kecemasan menghadapi pensiun yang diadaptasi dan dikembangkan oleh peneliti dengan menggunakan skala Likert berdasarkan komponen self effi cacy (Bandura, 1986) dan bentuk kecemasan menghadapi pensiun (Bucklew, 1980). Dari hasil analisa diperoleh diperoleh hubungan yang negatif antara self effi cacy dengan kecemasan menghadapi pensiun pada pegawai negeri sipil dengan nilai r = -.409 (p = .01). Artinya adalah semakin tinggi self effi cacy maka semakin rendah tingkat kecemasan pegawai negeri sipil yang akan menghadapi pensiun, dan sebaliknya semakin rendah self effi cacy maka semakin tinggi tingkat kecemasan pegawai negeri sipil yang akan menghadapi pensiun.

Abstract

Compact Fluorescent Lamps (CFL) are one of the non-linear load which depicts distorted wave containing harmonics. Harmonics are integer multiplication periodically of the fundamental frequency. Harmonics will worsen the quality of Compact Fluorescent Lamps, one of the results is shorten the lamp life due to excessive overheating. Harmonics can be calculated with Total Harmonic Distortion. This study discusses the effect of harmonic distortion on Compact Fluorescent Lamps, and make Low Pass Filter for reducing THD value. Tests were conducted in this study are testing the effect of the value of  to the value of power factor, the ratio of THD value, power factor and illumination of the expensive one with the cheap one. Based on the results of tests that have been carried out, the value of  has a negative effect on the value of the power factor. THD and power factor value in expensive lamps has no significant difference with cheap lamps, while the value of illumination on the expensive lamps have significant differences with cheap lamps. and illumination value of the lamps that have not been fitted with filters are bigger than the lamps that have been fitted with a filter, and the filter successfully reduce 88,03%  value of Compact Fluorescent Lamps.

Abstract

Configuration parameter tuning is an essential part of the implementation of Hadoop clusters. Each parameter in a configuration plays a role that impacts the ov erall performance of the cluster. Therefore, we need to learn the characteristics of said parameter and understand the impact in hardware utilization in order to achieve optimal configuration. In this paper, we conducted experiments that includes modifying configuration and performed benchmark to find out if there is any performance gain. TeraSort is the program that runs the benchmark, we measure the time needed to complete the sort of the set of data and the CPU utilization during the benchmark. We conclu de that from our experiments we can see significant performance improvements by tuning with the configurations. However, the results may vary between different cluster configuration.

Abstract

This research attempts to analyze risk and stock return of consumer sector and construction sector at Indonesian Stock Exchange. This research used the documentation method to collect the data. Data has been taken from Bloomberg Terminal. The sample is four corporations, with two corporations for each sector from 2011 until 2016. This research is using the Capital Asset Pricing Model (CAPM) and Arbitrage Pricing Theory (APT) for data analysis. Unfortunately, the Capital Asset Pricing Model (CAPM) has poor overall explanatory power, whereas the Arbitrage Pricing Theory (APT) model allows multiple sources of systematic risks to be taken into account and performs better than the CAPM, but both of the tests are considered. In regression analysis, the dependent variable used in the model is stock return. The result shows that inflation has insignificant effect on stock return. Furthermore, consumer sector has negative and significant effect on stock return. Conversely, construction sector has positive and significant effect on stock return.
