Abstract

In its effort to reduce congestion, Tangerang City Government has installed ATCS in several priority intersections using green wave concept (coordinated green light in priority intersections to reduce delay). The study investigated the change in CO2 emission in relation to the installation of ATCS on Jl. Jend Sudirman road section through traffic performance examination (of delay and travel time). Analysis showed that the installation of ATCS in the study area has improved the traffic performance, indicated by the reduction of average delay as much as 5,633 seconds (23,03%), increase in average speed as much as 1,56 km/hour (5,347%), reduction of average CO2 emission (15,26% at static and 6,208% while moving), therefore saving fuel consumption. In this study, delay has been identified as the variable having the greatest impact in the reduction of CO2 emission. This study argues that as positive results have been observable, the employment of ATCS for priority intersections optimization may be extended.

Abstract

AbstractThe purpose of this study is to determine the effectiveness of Quantum Learning combined with concrete objects media with conventional learning on mathematics subjects to activities and learning outcomes in one SD Negeri Salatiga. This experimental study used a type of Experimental Quasi. The sample of this study was the fifth grade students, amounting to 20 students as the experimental group and the control group with 20 students. The data collection instrument used in the study was a test of learning outcomes which included pretest and posttest. The data analysis technique used in this research is average difference test using Independent Sample T-test. The results showed that the experimental group was superior to the control group with the average value of the experimental group of 80.50> 77.25 the average value of the control group and the observer's study of the learning activity showed that the experimental group value was 7.60> 6.55 average score control group. From the hypothesis test, the 2 tailed significance value 0.0271 is smaller than 0.050 so Ho is rejected and Ha is accepted. Thus there are differences in the effectiveness of Quantum Learning combined with concrete objects media on learning mathematics on student activity and learning outcomes. Quantum Learning is recommended for teachers in mathematics learning.Keywords: Quantum Learning; Learning activity; Learning outcomesAbstrak Tujuan penelitian ini adalah untuk mengetahui efektivitas Quantum Learning yang dipadukan dengan media benda kongkrit dengan pembelajaran konvesional pada mata pelajaran matematika terhadap aktivitas dan hasil belajar di salah satu SD Negeri Kota Salatiga.

Abstract

Abstrak. Kerugian kredit, telah berulang kali diidentifikasi sebagai pemicu utama terjadinya kegagalan pada bank. Namun, studi yang menelaah faktor penentu kerugian kredit bank masih sangat jarang. Salah satunya adalah struktur kepemilikan keluarga. Padahal, 70% bank di Indonesia dimiliki oleh keluarga sehingga perbankan di Indonesia sangat rentan oleh eskpropriasi oleh kepemilikan keluarga terhadap pemegang saham minoritas. Oleh karena itu, tujuan utama penelitian ini adalah melihat pengaruh struktur kepemilikan keluarga dan pemerintah terhadap kerugian bank. Faktor penentu lainnya yang diteliti adalah pengaruh non linear ukuran bank terhadap kerugian kredit bank. Penelitian ini menggunakan the generalized method- of-moments (GMM) estimator yang dikembangkan untuk dynamic models of panel data. Dengan menggunakan data perbankan Indonesia dari tahun 2004 sampai dengan tahun 2014, hasil penelitian menunjukkan bahwa bank dengan kepemilikan keluarga memiliki kerugian kredit lebih besar dibandingkan bank lainnya (non keluarga). Tetapi, penelitian ini tidak menemukan pengaruh kepemilikan pemerintah terhadap kerugian kredit. Sementara ukuran bank ditemukan berpengaruh secara linear terhadap kerugian kredit namun tidak berpengaruh secara non linear. Implikasi penelitian ini adalah perbankan di Indonesia sebagai industri teregulasi harus memiliki aturan dan penegakan yang ketat dari Otoritas Jasa Keuangan agar bank dengan kepemilikan keluarga tidak menimbulkan kerugian kredit lebih besar dan merugikan pihak minoritas.Kata kunci: kerugian kredit bank, struktur kepemilikan keluarga, struktur kepemilikan pemerintah, ukuran bank, risiko bank Abstract. Credit losses, has been repeatedly identified as the principal cause of the failure of the bank. However, the extant literatures that examine the determinants of bank credit losses are still very rare. One is the structure of family ownership. In fact, 70% of banks in Indonesia are very concentrated on family ownership thus this condition may cause the entrenchment effect of family ownership on minority shareholders. Hence, the main purpose of this study is to investigate the influence of family ownership and government ownership on credit losses. Other determinant that being investigated is the possibility of non-linear effect of banks size on credit losses. This study used the generalizedmethod-of-moments (GMM) estimator developed for dynamic models of panel data. By using the Indonesian banking data from 2004 to 2014, the results shows that the bank with family ownership has a greater credit losses than other banks (non-family). However, this study fails to find the influence of government ownership on credit losses. While, the relationship between bank size and credit losses is linear and this study fails the non-linear relationship between the bank size and credit losses. The implications of this research are Financial Services Authority should enact and enforce the regulation that mitigate the expropriation of family ownership and consequently, the credit losses of Indonesian bank will be relatively reduced.Keywords: bank credit losses, family ownership, government ownership, bank size, bank risk

Abstract

This study is an attempt at solving the chronic problems of banking murabaha, notably the ribawi benchmark rate problem. To this end, the first stage of this study examines whether the recent solution for banking murabaha, namely Islamic Interbank Benchmark Rate (IIBR), is a sustainable solution to solve the problem. The Johansen cointegration test between IIBR and LIBOR, as an international benchmark rate, as well as IIBR and JIBOR, as an Indonesian one, is performed to prove that notion. The results suggest that IIBR has long-run equilibrium relationship with the two ribawi benchmark rates. IIBR hence does not fulfil the sustainability feature as a long-run solution for Islamic finance. The second stage of this study proposes the so-called universal Islamic banking system as a solution to remedy the problem. The proposed model is not only theoretically appealing but also practically possible to be implemented.

Abstract

This study aims to improve civics learning outcomes through a problem-based learning model in class X students concentrating on Fashion Design (TB 1) at SMK Muhammadiyah 5 Purwantoro in the 2022/2023 academic year. The subjects in this study were students in class X concentration on dressmaking skills (TB 1) in the odd semester of the 2022/2023 academic year, totaling 33 students, all of whom were female as the subjects receiving the action, while the subject of the action was the PPKn teacher class X Fashion Design (TB 1) namely as a researcher who observes the learning process. Methods of data collection is done through test techniques, observation and documentation. This action research was conducted in two cycles, each cycle consisting of: planning, action, observation and reflection. The use of the problem-based learning learning model with the demonstration method can improve PPKn learning outcomes for Class X students of Class X Fashion Design (TB 1) at Muhammadiyah Vocational School 5 Purwantoro in the 2022/2023 academic year. This can be seen from the average value of PPkn learning outcomes of students who also experienced an increase, namely before the action of 70.43 in the first cycle of 75.48 and in the second cycle of 77.59. In addition, the percentage of student learning completeness, namely before the action was 27%, in cycle I was 64% and in cycle II was 85%.
