Abstract

The presences of toxic gases are very harmful to health and safety of living things. One of these toxic gases is exhaust gases from motor vehicles, both two wheels and four wheels, such as CO (Carbon Monoxide). To be able to find out how many levels of CO in the flue gas of two-wheeled motor vehicles using gas sensors TGS 2600. Furthermore, the sensor voltage output changes TGS 2600 form an analog signal can be converted into a digital signal by ADC 0804 which in turn results in the form of binary conversion can be processed by the microcontroller AT89S51. Outcome of this AT89S51 microcontroller can be displayed on the LCD screen of parameter levels of CO in the flue gas motorcycles in units of ppm. Test results on several motorcycle shows that motorcycles that emit CO more than 9 ppm, then the bike does not meet health standards bases on Keputusan Menteri Negara Lingkungan Hidup Nomor: 141 tentang "Ambang Batas Emisi Gas Buang Kendaraan Bermotor tahun 2007"

Abstract

Palm oil is one of the products that are important to the economy of Indonesia. This study aims to analyze the performance of Indonesias CPO exports and to look for the influence of the independent variables such as production volume CPO, CPO consumption and the value of the rupiah against the U.S. dollar. The authors of this study tested using the Method of Error Correction Model. The time interval used is from 1998 to 2011 with the data quarter. The findings suggest that Indonesias CPO production volume variables exert a positive and significant impact on the number of Indonesian CPO exports in both the short and long term, then the variable volume Indonesia CPO consumption in the short and long term is also a significant effect on the number of Indonesian CPO exports but negatively related, this is due to the domestic CPO consumption greater that the capacity to export will be reduced. Variables of the Rupiah against the U.S. dollar also affects Indonesias CPO exports significantly and negatively related to both the short and long term and conditions of the depreciation of the rupiah exchange rate is not enough to effectively be driving exports. Estimates show that the close relationship between external demand caused exports to Indonesias export performance vulnerable to external shocks. Side factors are also a determinant of export performance. Keywords: palm oil, CPO consumption, Error Correction Model

Abstract

Penelitian ini bertujuan untuk menganalisis (1) perkembangan celah tabungan-investasi Indonesia, pada periode sebelum dan setelah krisis ekonomi pada pertengahan tahun 1997; (2) menganalisis retensi tabungan di Indonesia sebelum dan setelah krisis ekonomi pada pertengahan tahun 1997. Data yang digunakan dalam adalah data sekunder berupa publikasi-publikasi dari instansi yang terkait. Data dianalisis secara deskriptif melalui analisis tabel dan grafik. Peralatan statistik yang digunakan terutama adalah nilai rata-rata dan koefisien variasi volatilitas. Selanjutnya untuk mengukur koefisien retensi tabungan digunakan alat analisis korelasi Pearson. Variabel yang digunakan untuk menghitung korelasi tersebut adalah variabel dalam nilai persentase tabungan dan investasi terhadap PDB. Hasil analisis menemukan bahwa: (1) Krisis ekonomi telah menyebabkan perubahan celah tabungan-investasi di Indonesia, dimana pada periode sebelum krisis bernilai negatif (saving lebih kecil dibandingkan investasi) menjadi positif pada periode setelah krisis (tabungan lebih besar dibandingkan investasi. Kondisi ini terutama terjadi pada celah tabungan-investasi masyarakat. Sebaliknya untuk celah tabungan-investasi pemerintah relatif tetap bernilai negatif.; (2) Dari koefisien retensi tabungan menunjukkan tingkat mobilitas kapital di Indonesia masih rendah. Kondisi ini tidak berbeda baik pada periode sebelum krisis maupun setelah krisis.   Kata Kunci: celah tabungan, krisis ekonomi, retensi tabungan

Abstract

ABSTRAKPENENTUAN TORSI MINIMUM PENGGERAK ELEKTROMEKANIK KATUP PA-01/02/03 AA003 PADA SISTEM PENDINGIN SEKUNDER RSG-GAS. Katup memegang peranan penting dalam pengoperasian reaktor nuklir.  Sebagai pengatur aliran fluida, katup harus selalu dirawat. Pada perawatan katup yang menggunakan penggerak elektromekanik selain pengujian buka-tutup, juga pengaturan torsinya. Tujuan penulisan makalah yaitu untuk menghitung torsi pada katup sehingga dapat ditentukan torsi minimum yang diperlukan sebagai penggerak elektromekanik. Lingkup dibatasi pada perhitungan torsi katup sistem pendingin sekunder PA-01/02/03 AA003. Metode yang digunakan adalah dengan  menghitung torsi, untuk mencari data aliran, mencari data spesifikasi katup, mencari data dimensi pipa, menghitung penurunan tekanan dan menghitung torsi.Dari hasil perhitungan diperoleh bahwa harga minimum torsi yang bekerja pada katup PA-01/02/03 AA003 sebesar(TT) = 3982,986 Nm = 3,983 kNm. Disimpulkan bahwa torsi ini dapat digunakan untuk pengaturan perawatan katup PA-01/02/03 AA003 RSG-GAS.Kata kunci : Sistem pendingin sekunder, katup, torsi minimum ABSTRACTDETERMINATION OF MINIMUM TORQUE OF ELECTROMECHANICAL DRIVER OF THE PA-01/02/03 AA003 VALVE OF THE RSG-GAS SECONDARYCOOLING SYSTEM. Valve has an important role in the operation of nuclear reactor. As a fluid controller valve should be always maintenance. Beside the maintenance of valve using an electromechanical driver, the testing of opening and closing, as well as the torque setting should be pay attention. The purpose of writing this paper is to calculate of the torque of the valve so that it can be determined the minimum torque required as an electromechanical drive. The scope is limited on the calculation of the torque on the valve of PA-01/02/03 AA003 of the secondary coolant system.  The method used for calculation is by calculating the torque of valve in order to find the flowdata, specification valves data, pipe dimensions data, calculate pressure drop and calculate torque. Calculation result is shown that minimum value of torque working on the valve PA-01/02/03 AA003 is (TT) is 3982.986 Nm or 3,983 kNm. It is can be concluded that torque  can be used to control of maintenance setting of the PA-01/02/03 AA003 valve of the secondary cooling system of the RSG-GAS.Keywords: secondary cooling system, valve, minimum torque

Abstract

Low mastery of the ability to calculate multiplication in pe, the lesson is due to less precisely the model of learning and media used. So students become inactive, easily bored, and less attention to teacher explanations. Therefore to improve the multiplication counting ability Required model of learning with appropriate media. One of them is the model of learning by using the media objects nearby. Based on the results of a daily test of mathematics lessons on multiplication multiplication shows that less successful learning. In the case according to the teachers information in the daily learning has been explained orally, have been given examples, and even have been given the questions of practice and provide opportunities to students To ask, but they did not take advantage of the opportunity. This study aims to improve the ability to calculate multiplication fourth grade students of the first semester of S D Foreign N o. 33 Long Desert Sub Koto XI Tarusan. South Coastal District with total students 49 children, 25 children and 24 children Students daughter male student. The data in this study were obtained from interviews, questionnaires, observation results of action, and evaluation results. This study was conducted in two cycles. Each cycle is done based on the stages: Prepare an action plan, Implement action, Observation, and Analysis followed by reflection. The results showed that according to the results of observations of researchers on preaction is in students less active learning, easy tosaturate, and pay attention to students on teacher explanation is very small. In the first cycle-1 of the mastery of the material before the learning is given 31%, after the activity takes place students activeness shows: active students 58%, students are 30%, and 12% passive students. Student cooperation: active students 62%, students are 28%, and passive students 10%. While the result of average evaluation 68 with students complete 33 students and not complete 16 students.Hasi l-2 action in cycle action sebelun material penguasan 48%. After the action is done student activity: active students 78%, students are 18% and 4% passive students. Student cooperation: active students 84%, students are 14%, and 2% passive students. Evaluation result Average 76 students complete 46 complete students and 3 students not yet completed. Based on the above results kan It can be concluded that learning with the nearest media objects can improve the ability to calculate multiplication, increase student activity, and increase student cooperation in completing group tasks. Learning becomes enabling so students are not easily saturated
