EMPIRICAL POWER COMPARISON OF NON-NESTED TESTS FOR THE EVM: SOME MONTE CARLO EVIDENCE

Recently, Bodla and Bhatti (2007) revisited Davidson and MacKinnon’s (2002) well-known J test and noted that thought the test is simple to compute but lack small sample exact test computation properties. This paper is one of the attempts to compute a new version of the J test and compare its power performance with the various existing tests to see the relative strength of our test to be called as an approximately most powerful test. The main objective of this paper is to study Monte Carlo evidence on finite sample performance of the now modified non-nested tests of mismeasured regression models in EVM, Errors in Variables Models, setting to see if the power performance of the new test.Nonnested models, power & size of a test, Monte Carlo Simulation

Analisis Sungai Tiung Dalam Rangka Pengendalian Banjir

Banjir di DAS Tiung terjadi akibat meluapnya Sungai Tiung karena penampang sungai mengalami pendangkalan dan penyempitan. Penyebabnya berkaitan erat dengan kegiatan pendulangan intan yang tidak terkendali, mengakibatkan tanah menjadi gersang dimana resisten terhadap erosi, sehingga mengalirkan endapan ke alur sungai. Oleh karena itu diperlukan studi untuk menentukan besar debit banjir rencana dalam periode 25 tahun, sekaligus meninjau profil muka air sungai terhadap kondisi eksisting, yang akhirnya dapat dijadikan acuan dalam USAha pengendalian banjir.Tujuan dari penelitian adalah untuk menganalisis sungai tiung dalam rangka pengendalian banjir, dalam menganalisis Sungai Tiung ini, diperlukan beberapa analisis seperti analisis hidrologi yang mencakup analisis curah hujan maksimum dengan metode Probabilitas Frekuensi (Log Normal,Gumbel dan Log Pearson Tipe III) dan analisis debit banjir rancangan dengan metode empiris seperti metode Rasional praktis,Hasper, Der Weduwen, dan Hidrograf Satuan Sintetis Nakayasu.Pada analisis hidrolika , dalam penentuan elevasi muka air dan dimensi saluran normalisasi untuk debit periode 25 tahun digunakan program bantu Hec-Ras 3.0. Sedangkan analisis stabilitas lereng didukung dengan program bantu Xstable yang mengacu pada Modified Bishop Method.Hasil analisis hidrologi memperlihatkan besar banjir periode 25 tahun menunjukkan harga debit sebesar 54,826 m3/d dan berdasarkan hasil analisis hidraulika, besarnya dimensi saluran normalisasi untuk periode tersebut adalah 9 m (lebar dasar) dan 3,6 m (tinggi saluran) dengan talud 1: 1,5. Jarak air yang melimpas di kiri dan kanan tepi alur sungai diprediksi sebesar 8,12 m untuk periode ulang 50 tahun. Nilai keamanan terhadap keruntuhan lereng (SF) diperoleh 2,33 untuk bagian hulu dan 1,903 untuk bagian hilir dengan menggunakan program Xstable

Current Results from the RRFID Kinematic Survey: Apparent Speeds from the First Five Years of Data

We present current results from our ongoing project to study the parsec-scale relativistic jet kinematics of sources in the U.S. Naval Observatory's Radio Reference Frame Image Database (RRFID). The RRFID consists of snapshot observations using the VLBA plus up to 9 additional antennas at 8 and 2 GHz. The Image Database currently contains about 3000 images of 450 sources from 1994 to 2004, with some sources having images at 20 epochs or more. We have now completed analysis of the 8 GHz images for all sources observed at 3 or more epochs from 1994 to 1998. The completed analysis comprises 966 images of 87 sources, or an average of 11 epochs per source. Apparent jet speeds have been measured for these sources, and the resulting speed distribution has been compared with results obtained by other large VLBI surveys. The measured apparent speed distribution agrees with those found by the 2 cm survey and Caltech-Jodrell Bank (CJ) survey; however, when a source-by-source comparison is done with the 2 cm survey results, significant disagreement is found in the apparent speed measurements for a number of sources. This disagreement can be traced in most cases to either an insufficient time baseline for the current RRFID results, or to apparent component mis-identification in the 2 cm survey results caused by insufficient time sampling. These results emphasize the need for long time baselines and dense time sampling for multi-epoch monitoring of relativistic jets.Comment: 4 pages, To be published in the Proceedings of the 7th European VLBI Network Symposiu

Pengaruh Motivasi Terhadap Minat Mahasiswa Untuk Mengikuti Pendidikan Profesi

Penelitian ini bertujuan untuk menganalisis pengaruh dimensi motivasi terhadap mahasiswa untuk mengikuti Pendidikan Profesi Akuntan. Populasi penelitian adalah seluruh mahasiswa akuntansi di Kota Semarang. Sampel penelitian berjumlah 388 yang berasal dari empat perguruan tinggi, yaitu UNNES, UNDIP, UNIKA dan UDINUS. Variabel independen dalam penelitian ini yaitu motivasi yang terdiri atas motivasi kualitas, motivasi karir, motivasi ekonomi, dan motivasi sosial. Sedangkan variabel dependennya adalah minat mengikuti PPA. Pengumpulan data dilakukan dengan kuesioner, dan data dianalisis dengan menggunakan metode analisis regresi berganda. Hasil penelitian menunjukkan bahwa motivasi berpengaruh terhadap minat mahasiswa untuk mengikuti PPA sebesar 23,2%. Berdasarkan temuan tersebut, disarankan kepada lembaga penyelenggara PPA untuk selalu mengembangkan kurikulum PPA

Coherently controlled entanglement generation in a binary Bose-Einstein condensate

Considering a two-component Bose-Einstein condensate in a double-well potential, a method to generate a Bell state consisting of two spatially separated condensates is suggested. For repulsive interactions, the required tunnelling control is achieved numerically by varying the amplitude of a sinusoidal potential difference between the wells. Both numerical and analytical calculations reveal the emergence of a highly entangled mesoscopic state.Comment: 6 pages, 6 figures, epl2.cl

Model Jaringan Utilitas Terpadu Bawah Tanah di Kota Banjarbaru

Banjarbaru has prepared as the capital of South Kalimantan which has a barometer was grown as the center of government, economic, education and services, so it can be a magnet for people who wants to get their opportunity. This situation should become to increase facilities and infrastructure to support the activities and movements of populations. It can make governments gets many tasks. The research aims to know the effectiveness of existence and give a solution or the alternative model to handle the utility of underground network in Banjarbaru, for the future from management and institution mainly. This problem is interesting to study as material for making an integrating model for the utility of underground network continuously. The experiment was conducted by using Qualitative methods. Data was collected by direct observation, interview and questioner to strengthen the data. Then, the data was analyzed by using SWOT analysis. The result showed that the utility of underground network ( existing ) is perceived by society is not effective because it is usually digging holes in the same place for different installation. So, the management of handling in the utility of underground network should be performed or handle as integrating and professional, not detrimental and stakeholders are leaded by the government in Banjarbaru. The result also provides the solution or alternative model to gain all underground networks such as Telkom, PDAM, drainage, PLN, sanitation and gas. This model can applicate in Banjarbaru area, particularly for the government of South Kalimantan especially at offices because it was designed with environmental sustainable management

Fungsi Kawasan dan Strategi Pengelolaan Hutan Lindung Wosi Rendani Kabupaten Manokwari

The results of the research showed that the forest of Wosi Rendani protection has slope 21.9% (score 60), soil type podsolic/ ultisol (Score 60) and 12.86 rain intensity (score 10), altitude 210 m asl, with a total score of 130 as a buffer zone. Perceptions of respondents unanimously positive 64.17% and 75% attitude towards local community-based management. This is due to the location of protected areas that are near human settlements and local immigrant who feared if the protected forest next to landslides and people lack of clean water. Inside the forest, there is an object HLWR areas and attractions such as waterfalls, caves, springs, pools that can be used as the establishment of protected forest. Protected forest of Rendani Wosi area has considerable potential to support regional management efforts such as the potential for flora and fauna, water, waterfalls and springs and caves as well as the support of the community around the area, but the legality of the area there has been no major obstacles in the management of this protected fores
