Technical Efficiency and Productivity Analysis in Indonesian Provincial Economies

By using the stochastic frontier methodology, this study investigates the technical efficiency and total factor productivity (TFP) growth in Indonesian provincial economies during the period from 1993 to 2000. In addition to the estimation of provincial technical efficiency, factors that contribute to technical inefficiency are also examined and the TFP growth is decomposed into technological progress, the scale component and the change in technical efficiency. The results reveal that average technical efficiency is only around 50%. Our results reveal that the mean years of schooling and sectoral differences affected technical efficiency. The TFP grew, on average, in the range from 1.65% to 5.43% with an average growth of 3.59%. In twenty out of twenty six provinces the TFP growth was driven by efficiency changes while in four provinces the TFP growth was driven by technological progress. Further, we note that the Asian crisis affected the TFP growth and the western provinces suffered from the crisis more than the eastern provinces

Cost efficiency, Economies of Scale, Technological Progress and Productivity in Indonesian Banks

This study estimates cost efficiency, scale economies, technological progress and productivity growth for Indonesian banks over the period 1993-2000. Overall the cost efficiency of all banks during this period was 69.82%. However, on average the efficiency of banks prior to the Asian crisis and after the Asian crisis were 79.67% and 53.40% respectively. Moreover, the results also indicate that private-owned banks and joint venture/foreign banks were more efficient than public-owned banks. Furthermore, as expected large banks tend to be more efficient as compared to smaller banks. Total factor productivity growth for Indonesian banks over the period 1993-2000 was -3.14%. However, before the Asian crisis, Indonesian banks productivity decreased by 1.48%, while after the crisis it decreased by 6.45%

Efficiency and Productivity Analyses of Indonesian Manufacturing Industries

This study estimates the technical efficiencies and total factor productivity (TFP) growth in food, textile, chemical and metal products industries during 1993 to 2000 in Indonesia by using the stochastic frontier model. Furthermore, the determinants of inefficiency are also analyzed and the TFP growth is decomposed into technological progress, scale component, and efficiency growth. The results reveal that the food, textile, chemical and metal products sectors are on average 50.79%, 47.89%, 68.65% and 68.91% technically efficient respectively. It is noted that ownership contributed to technical inefficiency in the food sector; location and size contributed to technical inefficiency in the textile sector, whereas size, ownership and age contributed to inefficiencies in the chemical and metal products sectors. The estimates of TFP growth indicate that productivity in Indonesian manufacturing industries decreased at the rate of 2.73%, 0.26%, 1.65% and 0.5% in food, textile, and metal products respectively, whereas in the chemical sector, it increased at a rate of 0.5% during the period of the study. The decomposition of TFP growth indicates that the growths are driven positively by technical efficiency changes and negatively by technological progress in all four sectors

The urgency of asset confiscation sanction in tax crimes

Law Number 16 of 2009 concerning General Provisions and Tax Procedures (UU KUP), regulates administrative sanctions and criminal sanctions. The KUP Law method does not yet regulate how to save the loss of state revenue because it does not regulate the implementation of criminal fines, the legal implications of different decisions that cause legal uncertainty, injustice and have not provided benefits, especially in an effort to collect taxes. The purpose of this paper is to find out, analyze, and find the urgency of regulating criminal sanctions for the deprivation of assets in tax crime. This study is normative legal research with a legislation approach, historical approach, comparative law approach, conceptual approach, and case approach. The legal materials used are primary and secondary legal materials. Analysis of legal material is done with a descriptive perspective. The results of this study indicate that the inclusion of fine sanctions in the KUP Act turns out to lead to different interpretations resulting in legal uncertainty and does not provide economic benefits for the state in law enforcement, because the sanctions for fines are not complemented by implementing sanctions in the form of additional criminal sanctions in the form of confiscation of assets belonging to the defendant or an act (maatregel) in the form of requiring improvement of corporate governance in accordance with good corporate governance or placement of a legal company, where an economic crime is committed under a certain period of time, so that in the future the KUP Act, additional sanctions or actions to strengthen / complete in the future criminal sanctions for fines

OPTIMASI PENGELASAN DISIMILAR METAL SS 304 DAN MILD STEEL UNTUK MEMINIMALKAN EFEK DISTORSI

The manufacturing industry is growing very rapidly, including welding. The welding process has an increasing trend, especially in the fields of ship trusses, bridge structures, railway construction, and others. Welding has the character of a strong connection, lightweight and simple. Welded joints for dissimilar metals have developed quite significantly and have their challenges. Metals that are widely used include SS 304 and mild steel. One of the problems with meta-dissimilar welding is distortion. Distortion occurs due to excessive thermal stress during the welding process, resulting in a change in the dimensions of the metal. This results in a fairly difficult assembly process. The purpose of this study was to find the optimal welding parameter setting value for welding between SS 304 material and mild steel, using Gas tungsten arc welding (GTAW). Welding parameters were searched using the Taguchi method. Welding parameter variables include plate thickness (mm), welding length (mm), strong current (A), and Welding Angle (o). The results of the combination of factors and optimal levels for welding SS 304 and mild steel plates that are recommended are using a welding current of 100A, the plate thickness of 3 mm, a welding angle of 80o, and a welding length of 100 mm.Industri manufaktur berkembang sangat pesat termasuk di dalamnya pengelasan. Proses pengelasan memiliki tren yang meningkat terutama bidang rangka kapal, struktur jembatan, konstruksi kereta api dan lain-lain. Pengelasan memiliki karakter sambungan yang kuat, ringan dan sederhana. Sambungan las untuk logam yang berbeda memiliki perkembangan yang cukup signifikan dan memiliki tantangan tersendiri. Logam yang banyak digunakan misalnya material SS 304 dan Mild Steel. Salah satu kendala pengelasan beda logam adalah terjadinya distorsi. Distorsi terjadi dikarenakan tegangan thermal yang berlebih pada saat proses pengelasan, sehingga mengakibatkan perubahan dimensi pada logam tersebut. Hal ini mengakibatkan proses perakitan yang cukup sulit.  Tujuan penelitian ini adalah mencari nilai pengaturan parameter pengelasan yang optimal untuk pengelasan antara material SS 304 dan Mild Steel, menggunakan pengelasan Gas Tungsten Arc Welding (GTAW). Parameter pengelasan dicari menggunakan metode Taguchi. Variabel parameter pengelasan meliputi tebal plat (mm), panjang pengelasan (mm), kuat arus (A), dan sudut pengelasan (o). Hasil penelitian menunjukkan kombinasi faktor dan level optimal untuk pengelasan plat SS 304 dan Mild Steel yang direkomendasikan adalah menggunakan ketebalan plat 3 mm, panjang pengelasan 100 mm, arus las 100 A, dan sudut pengelasan 80o
