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

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

Upaya Meningkatkan Aktivitas dan Hasil Belajar Mahasiswa melalui Penerapan Model Pembelajaran Inkuiri pada Mata Kuliah Konsep Dasar IPA 2 di Program Studi Pendidikan Guru Sekolah Dasar Tahun Akademik 2013/2014

In line with the competency-based curriculum at the University of Riau, the effort to improvelearning basic concepts of science 2 courses puts emphasis on understanding the concept ofmatter, which is based on students' learning activities through scientific inquiry.Implementation of action research consists of two cycles in PGSD JIP University of Riau onthe odd semester of 2013/2014 with 55 third semester students. Based on the research results,lecturing process by applying the model of inquiry learning, students' activity increased inwhich in the first cycle all activities are good category except activity I and II are faircategory. Meanwhile students' activity in first and fourth in cycle II is good category, andvery good category in second, third, fifth, and sixth activity. Temporarily student's learningoutcomes increased from pre-tests with an average65.45 into 77,0 in daily test I and 77.45onthe daily test II. Improvement from initial data to the first cycle was 11.55, while the datafrom the beginning to the second cycle increased 12 points. In general the improvement ofstudents'learning is possible because the learning model used is inquiry learning so thatlearning becomes active which centered into students by presenting a problem, then studentsare asked to carry out a simple experiment using equipment and tools, using data, arrangingreports, communicating the results of observations based on concepts and learned principles

Analisis Kurikulum Pendidikan Lingkungan Hidup pada Sekolah Dasar Pekanbaru

The purpose of this research is that to create even distribution and understanding about life areaeducation to primary school students that will obtain students' attitudes in doing actionsappropriating to the concept of life area education and create an alternative the development of lifearea education in Pekanbaru based on national curriculum or local curriculum. So that it can givecontribution to the curriculum in in real on the framework of life area education. The data used in thisresearch were primary and secondary data. Primary data sources from survey (direct observation) atschool, interview with stakeholder related to Head of Education Department, headmasters, andteachers. Primary data were also obtained by giving qutionare to headmasters, teachers, and studentsrelated to cognitive, affective, and psychomotor about life area education. Secondary data wereobtained from school condition like document of PLH activities at school and also stakeholders. Basedon the data of school curriculum analysis to life area education that it can be integrated into fivesubjects that are religion, civics, science and technology, art, and physic education. Based oneducation stakeholder analysis that they supported the life area education to put into local curriculumand to be implemented into daily life at school. Based on analysis data on knowledge and attitudesthan primary school students fully understood about life area education, and they have done to careabout school area

Rituals Of Politeness In Bugis Society

Paper ini membahas cara-cara yang dipakai oleh masyarakat Bugis mengekspressikan kesopanannya melalui sejumlah tindak tutur (speech acts) seperti ucapan salam, terima kasih, penyampaian undangan, dan permohonan maaf. Penelitian diadakan pada dua lokasi masyarakat Bugis: di daerah pedesaan, Awangpone, Bone dan di daerah perkotaan, Parepare. Pengambilan data dilakukan dengan partisipan observasi, interview, dan merekam percakapan. Hasil penelitian menunjukkan bahwa masyarakat Bugis menggunakan tindak tutur tersebut di atas untuk menunjukkan kesopanan mereka. Tindak tutur tersebut di atas juga digunakan sebagai ritual dalam suatu pertemuan. Tindak tutur ini juga berfungsi sebagai basa-basi yang lebih menunjukkan kesopanan mereka

The subject of the researchdetermined by random toward experimental and control groups. The results of this studyshowed that there was differences class between implements the inquiry learning andconventional learning. Mean score N-Gain science of process skills students washighest in primary schools reached 0.29 A, while for the N-Gain lowest in primaryschools C of 0.15 As for the indicators of science-process skills, process skills of thehighest indicators in the experimental class there is the aspect of the hypothesis, whilethe lowest indicator contained in the aspect of the question. In the control class there areindicators that contained by aspects of the hypothesis while the lowest was on aspects ofobservation. The results visible experimental class science process skills results showedhigher levels of N-gain control of the class.
