"ABSTRAKPenelitian ini memeriksa hubungan cross-sectional antara turnover shock saham di sesi perdangangan pasca-penutupan IDX dan efisiensi harga pembukaan. Hasil penelitian menemukan adanya pelemahan efisiensi harga pembukaan pada transaksi pembuka. Hal ini konsisten dengan resiko information asymmetry. Penelitian ini juga mendukung argumen bahwa resiko information asymmetry tidak berkaitan dengan market friction walaupun kedua faktor tersebut behubungan dengan mikrostruktur harga aset dan bahwa ketersediaan opening call auction pada saham-saham paling liquid mungkin tidak meningkatkan efisiensi harga pembukaan saham-saham tersebut.

ABSTRACT

This paper examines cross-sectional relationship between stocks? magnitude of turnover shock in IDX post-close trading session and their price efficiency in the opening. The result confims that the shock is significantly decreasing opening price effeciency in the opening trade. This finding is consistent with information asymmetry risk. Additionally, this research confirms that information asymmetry risk is unrelated to market friction although both of them are related to microstructure asset pricing and that availability of opening call auction in stocks with highest liquidity may not improve their opening price."

"ABSTRAKKinerja Bank Pembangunan Daerah BPD dipengaruhi oleh beberapa faktor termasuk faktor keuangan, makroekonomi, sosial, dan politik. Kinerja BPD tersebut diukur dengan menggunakan profitabilitas ROA dan ROE , efisiensi BOPO , dan bank risk NPL dengan total 1144 observasi. Teknik estimasi yang digunakan dalam penelitian ini adalah Generalized Method of Moment GMM untuk menganalisis data yang didapatkan dari Bank Indonesia, World Bank, BPS, dan Otoritas Jasa Keuangan OJK selama periode observasi 2005 ndash; 2015. Hasilnya menunjukkan bahwa ROA secara positif dipengaruhi oleh bank size, net interest margin, non-interest margin, government expenditure, bank listed, dan latar belakang professional dari gubernur. Selanjutnya ROE secara positif dipengaruhi oleh bank size, net interest margin, non-interest income, capital adequacy ratio, government ownership pada BPD, unemployment, bank listed, dan latar belakang professional dari gubernur. Kemudian BOPO secara negatif dipengaruhi oleh interest income, unemployment, dan real GDP growth. Sedangkan bank risk secara negatif dipengaruhi oleh interest income dan joint ownership. Berkenaan dengan factor politik, penelitian ini menemukan bahwa periode pemilihan kepala daerah akan mendorong peningkatan profitabilitas, namun jika gubernur terpilih adalah incumbent yang menjabat pada periode pertama, maka hal ini cenderung akan menurunkan profitabilitas dalam jangka panjang. Selanjutnya adalah apapun latar belakang dari gubernur akan menurunkan bank risk, namun demikian hanya gubernur yang memiliki latar belakang professional termasuk militer yang secara konsisten akan meningkatkan profitabilitas dan menurunkan bank risk dalam jangka panjang. Penelitian ini menemukan adanya trade-off terkait pencapaian yang ingin dicapai oleh BPD. Jika BPD ingin mengejar pertumbuhan profitabilitas yang cepat, maka trade-off adalah meningkatkanya inefisiensi dan bank risk. Sedangkan jika yang ingin dicapai adalah efisiensi yang tinggi dan bank risk yang rendah, maka BPD harus menghadapi potensi perlambatan pertumbuhan profitabilitas dalam jangka panjang. Dengan kata lain, terdapat tingkat profitabilitas tertentu yang dapat dicapai oleh BPD dengan potensi inefisiensi dan risiko yang masih dapat dimitigasi.

ABSTRACTRegional Development Bank BPD performance is affected by several factors including financial, macroeconomic, social, and political factors. BPD performance itself is measured by profitability ROA and ROE , efficiency BOPO , and bank risk NPL with 1144 total observations. The research employs Generalized Method of Moment System to analyze the data obtained from Bank Indonesia, World Bank, BPS, and Otoritas Jasa Keuangan 2005 2015. The result shows that ROA is positively influenced by bank size, net interest margin, non interest income, government expenditure, publicly listed, and professional background of governor. Meanwhile ROE is positively determined by bank size, NIM, non interest income, CAR, government ownership of BPD, unemployment, being publicly listed, and professional background of the governor. Moreover, BOPO is negatively affected by interest income, unemployment, and real GDP growth. Meanwhile bank risk is negatively affected by interest income and joint ownership. In terms of political factors, it is found that the period of election would drive higher profitability, however if the elected governor was an incumbent governing in the first period of its leadership, the profitability tended to decrease in the long run. Moreover, any background of the governor will reduce bank risk, however it was only professional background including military that would consistently drive higher profitability and reduce risk in the long run. The research found trade off regarding which performance BPD intends to prioritize. If it prioritizes profitability, then the trade will be inefficiency and high risk. Instead, higher efficiency and lower risk may not compensate the increase in profitability. In other words, there is certain level of profitability BPD could achieve with certain level of inefficiency and risk. "

"Pada masa depan kebutuhan bahan bakar minyak akan semakin meningkat namun ketersediaan bahan bakar minyak yang merupakan sumber daya yang tidak dapat diperbaharui akan semakin menipis. Selain masalah ketersediaan bahan bakar yang semakin menipis, bahan bakar yang akan digunakan juga harus memperhatikan dampak terhadap lingkungan, dalam hal ini adalah pengurangan emisi gas buang. Untuk itulah perlu dicari bahan baker minyak yang terbarukan dan juga ramah lingkungan. Salah satu solusinya adalah bahan bakar biodiesel dari minyak kelapa yang dihasilkan dari tumbuhan melalui proses transesterifikasi. Biodiesel dibuat dengan proses batch dengan prosesor BDP-10FG-BV dengan methanol sebagai pereaksi dan NaOH sebagai katalis. Terdapat tiga langkah dalam pembuatan biodiesel. Pertama adalah pencampuran trigeliceride, methanol and NaOH. Kemudian yang kedua adalah memisahkan biodiesel dari gliserol, dan yang terakhir adalah pencucian biodiesel dengan menggunakan air murni. Prosesor BDP-10FG-BV cocok untuk produksi berskala kecil karena memiliki hasil yang berkualitas baik. Kelemahan dari proses ini adalah waktu produksi yang lama. Biodiesel yang telah dibuat perlu diuji untuk mengetahui apakah bias menggantikan solar. Pengujian yang dilakukan adalah pengujian spesifikasi biodiesel dan pengujian prestasi mesin serta gas buang. Dalam pengujian prestasi mesin, biodiesel minyak kelapa dicampur dengan solar dengan komposisi 5% biodiesel 95% solar (BM-5), komposisi 10% biodiesel 90% solar (BM-10), komposisi 20% biodiesel 80% solar (BM-20). Dari hasil pengujian spesifikasi biodiesel, didapatkan bahwa biodiesel minyak kelapa dengan pereaksi methanol masih memiliki gliserol total yang tidak sesuai dengan standar syarat mutu biodiesel. Gliserol total pada biodiesel minyak kelapa dengan pereaksi methanol memiliki kelebihan 0,0489 [% - massa] dari standar. Sedangkan dari hasil pengujian prestasi mesin, dapat disimpulkan bahwa biodiesel minyak kelapa dengan pereaksi methanol memiliki nilai efisiensi thermal yang lebih baik dari biosolar dan juga memiliki opasitas yang lebih baik dari solar maupun biosolar. Campuran biodiesel yang terbaik adalah BM-10 untuk efisiensi thermal pada bukaan throttle tetap dan BM-20 pada putaran tetap.

In the future the demand of oil fuel will increase, but because oil fuel is a non renewable energy the supply will decrease. Beside that problem, oil fuel that we used must be care with environment, in this case is reducing of exhaust gas. For that reason, we must search for the oil fuel which made from renewable energy and care with environment. One of the solutions is biodiesel of coconut oil which produce by transesterification process. Biodiesel produced by batch processor BDP-10FG-BV with methanol and catalyst NaOH. There are three step in producing biodiesel. First mixing trigeliceride, methanol and NaOH. Then the second step is separating biodiesel from glycerol and the last step is washing biodiesel with pure water. Processor BDP-10FG-BV suitable for small scale production because have a good quality result. The weakness is the process need a lot of time. Biodiesel that we made have to be tested to compare with diesel fuel. There are two kind of tested, biodiesel specification test and engine perform and opacity test. In engine perform and opacity test, biodiesel from coconut oil are blended with diesel fuel. The percentage of blending are 5% biodiesel and 95% diesel fuel (BM-5), 10% biodiesel and 90% diesel fuel (BM-10), 20% biodiesel and 80% diesel fuel (BM-20). From the biodiesel specification test result, we got that coconut biodiesel with methanol still had unsuitable total glycerol value from biodiesel standardization. Total glycerol from coconut biodiesel with methanol have 0,0489 [% - mass] surplus than standard. From engine perform and opacity test we got that coconut biodiesel with methanol had better thermal efficiency than biodiesel fuel (biosolar) and had better opacity than biodiesel fuel (biosolar) and diesel fuel (solar). The best blending are BM-10 for thermal efficiency at constant throttle opened and BM-20 at constant rpm. For opacity, the best blending are BM-5 at constant throttle openedand BM-20 at constant rpm."
