Abstract

An artificial neural network analysis based on the self-organizing map (SOM)  was used  to  examine  patterns  of  satellite  imagery.  This  study  used  3  ×  4  SOM  array  to  extract patterns  of  satellite-observed  chlorophyll-a  (chl-a)  along  the  southern  coast  of  the  Lesser Sunda Islands from 1998 to 2006. The analyses indicated two characteristic spatial patterns, namely the northwest and the southeast monsoon patterns. The northwest monsoon pattern was characterized by a low  chl-a concentration. In contrast, the southeast monsoon pattern was  indicated  by  a  high  chl-a  distributed  along  the  southern  coast  of  the  Lesser  Sunda Islands.  Furthermore,  this  study  demonstrated  that  the  seasonal  variations  of  those  two patterns  were  related  to  the  variations  of  winds  and  sea  surface  temperature  (SST).  The winds  were  predominantly  southeasterly  (northwesterly)  during  southeast  (northwest) monsoon, drived  offshore (onshore) Ekman transport and  produced  upwelling (downwelling) along  the  southern  coasts  of  the  Lesser  Sunda  Islands.  Consequently,  upwelling  reduce dSST  and  helped  replenish  the  surface  water  nutrients,  thus  supporting  high  chl-a concentration. Finally, this study demonstrated that the SOM method was very useful for the identifications of patterns in various satellite imageries.

Abstract

This study aims to determine the condition of ownership ratio proxyed by equity, the efficiency ratio proxyed by BOPO, profitability ratios proxied with Return On Asset, and company value and to find out how much influence of variable ownership and efficiency to profitability impact on firm value at 18 banking companies listed on the BEI period 2008-2015. This research uses descriptive and verificative methods. Data analysis methods used are multiple regression, multiple correlation, and coefficient of determination. The results showed that the ratio of ownership and efficiency ratio simultaneously and partially have significant effect on profitability. The dominant variable is the ownership ratio. Profitability has a significant effect on corporate value.

Abstract

Uncertainty in an increasingly competitive business environment, especially in the raising and emergence of several new companies in travel transportation services, should encourage a company to be able to have better performance to compete. Companies are faced with various threats and opportunities that emerge in the business environment, thus exposed to the uniformity of the company?s performance measurement tools as an instrument of the company?s performance evaluation. Measurement of company performance applied by Baraya Travel Bandung still use traditional performance measurement, incomprehensive and not optimal yet. Baraya Travel Bandung needs a performance measurement tool that can provide an overview of the overall achievement of the company?s business. The design of performance measurement tool that became the purpose of this research is Balanced Scorecard. The design of performance measuring tools using the Balanced Scorecard begins with translating the company?s vision, mission and strategic objectives that are linked into four perspectives in the Balanced Scorecard.
