Abstract

Tobacco industry is one of important manufacturing industry in Indonesia. There are several changes in structure, performance, and behavior of this industry during 1991-2008. This study aim is to analyze the differences between clove cigarette and white cigarette industries with SCP method. Analysis of industrial structure with CR4 index and barriers to entry. Industry performance is measured by Price Cost Margin (PCM) approach. Factors that affect the performance itself are analyzed by the Ordinary Least Square (OLS) method. The results of structural analysis show that the level of industry concentration of clove cigarettes went from tight oligopoly (84.29 percent) to medium oligopoly (52.65 percent) during research period. In contrast, white cigarette industry remained in tight oligopoly level with an average value of CR4 about 94.33 percent. The average value of MES which reflects the barrier to entry in white cigarette industries is higher (95.17 percent) than in cigarette industries (72.85 percent). Regression analysis on a clove cigarette industry indicates that the variable X-eff and growth are significantly positive, whereas a variable number of firms significantly negative effect on PCM. In white cigarette industry, a significant variable to the PCM is the X-eff  (0.366799). The analysis of behavior between the two industries cannot be separated from government regulation, especially in setting of the selling price. Promotion, although it increasing production costs, remains to be important strategy to maintain the industry market share.

Abstract

One of commodity which is important to be fulfilled is fruit. From producer side, it has been available much in Lampung Province but has not been utilized optimally by consumer. This study purposed to analyze the factors influencing fruit demand and the response of demand changes due to shifting of price and income. The analysis was conducted by using AIDS (Almost Ideal Demand System) model and the parameter was estimated by using SUR (Seemingly Unrelated Regression) method. The results stated that the fruit demand was influenced by the fruit price (either own-price or cross-price), expenditure, and the number of household members. The elasticity shows that the own-price for all kinds of fruit is inelastic. The cross-price elasticity indicates that there are some fruits that have substitution or complementary relationship among them and in all types of fruits, income elasticity has positive sign.

Abstract

n 2012, the electronic payment system transactions reached IDR 104.830 trillion or increase 46,52% from the previous year.  PT. XYZ is the  pioneer in the electronic payment system Indonesia  and still one of the leading companies in electronic payment system interbank, through ATM (Automatic Teller Machine) and EDC (Electronic Data Capture) in Indonesia.  In 2012 the company spent USD 3,4 million on software tandem from a foreign vendor.  Therefore it is important to study (1) policy on the modal structure of the company, (2) the working capital policy of the company, (3) the monetary performance relationship of the company based on the 2 policies.  The method used to analyze the data is multiple linear regression analysis; this method is used to calculate the relationship between the structure variable of the capital and working capital.  The result is; 1) the structure policy on the capital of the company is in accordance with the Pecking Order theory where the company uses their own capital before applying the long term debt to the others, 2) the inefficient policy on the company’s working capital is because most of the active asset is in monthly deposit bonds and even extended  the active debt, 3) the relationship between short term debt and liquidity ratio is negative while the total debt (short and long term) has a positive correlation with the solvability/leverage ratio of the company.  The research recommends the management to decrease the active asset and uses it for long term investment not only for timed deposit.Keywords:  ATM, EDC, capital structure, financial performance     AbstrakVoulme transaksi dalam menggunakan sistem pembayaran elektronis pada tahun 2012 mencapai Rp104.830 triliun atau meningkat sekitar 46,52% dari tahun sebelumnya. PT XYZ adalah salah satu perusahaan pionir dalam sistem bidang pembayaran elektronis di Indonesia dan tetap menjadi pemain utama dalam sistem pembayaran elektronis antar bank, ATM (Automatic Teller Machine) dan EDC (Electronic Data Capture). Di tahun 2012 perusahaan membeli software tandem dari vendor luar negeri dimana menghabiskan dana USD 3,4 juta, dengan pembelian ini maka dari itu penting untuk di teliti: 1) kebijakan struktur modal perusahaan, 2) kebijakan modal kerja  perusahaan dan 3) hubungan kinerja keuangan perusahaan berdasarkan dua kebijakan tersebut. Metode yang digunakan adalah analisis regresi linier berganda, mengukur hubungan variabel struktur modal dan modal kerja perusahaan. Pada penelitian telah menemukan: 1) kebijakan struktur modal perusahaan sejalan dengan teori Pecking Order, dimana perusahaan lebih menggunakan dana modal sendiri sebelum menggunakan hutang jangka panjang pada pihak lain, 2) kebijakan modal kerja perusahaan kurang efisien, dikarenakan sebagian besar asset lancar adalah dalam bentuk deposito berjangka bulanan dan bahkan melebihi hutang lancer itu sendiri, dan 3) hubungan antara hutang jangka pendek dan rasio likuiditas adalah negative, sedangkan total hutang (jangka pendek dan jangka panjang) berkorelasi positif dengan rasio solvabilitas/leverage perusahaan. Penelitian ini menyimpulkan manajemen untuk lebih mengurangi asset lancer mereka dan lebih menggunakan asset tersebut untuk investasi jangka panjang, bukan hanya untuk deposito berjangka.Kata kunci: ATM, EDC, regresi, struktur modal, kinerja keuangan

Abstract

Global financial crisis has given negative effects for economic growth especially in banking industry. This research aimed to analyze the efficiency and productivity of banks before and after the financial crisis. To examine the bank efficiency, this research used Data Envelopment Analysis (DEA), and the Malmquist Index was used to determine the bank productivity. This research concluded that Indonesian banking is inefficient in its intermediation function. The results showed that the performance efficiency score before crisis was 0.806, and the after crisis score was 0.812. The banks that were efficient are shown in Bank Mandiri (Persero), Tbk; Bank Rakyat Indonesia (Persero), Tbk; and Bank Central Asia, Tbk which have the highest assets. Banks with high assets have extensive market forces and networks making them more efficient than banks with smaller asset. That indicates a strong impact of the total assets to the bank efficiency level. Citibank NA and Standard Chartered Bank, known as foreign banks, are also efficient. The bank productivities after crisis are increasing. The results showed that Malmquist’s bank productivity was increasing during the research period, and the score was 1.002, indicating that technological change (frontier shift effect) index is the major source of productivity. Technological changes would support banks to be more efficient and productive.Keywords: Banks, data envelopment analysis (DEA), malmquist index, Global financial, financial crisisAbstrak: Krisis keuangan global telah memberikan dampak buruk bagi perkembangan perekonomian dunia khususnya perbankan.
