This study aims to analyze the influence of determinant factors: (i) exchange rates, (ii) inflation, (iii) CDS spreads, (iv) bid-ask spreads, (v) overnight rate, (vi) CB’s rate (Central Bank Rate), and (vii) oil prices on Government bond yields. The data used are monthly data in the period 2012 - 2018. The research method used is the Vector Auto Regression (VAR) approach. Our analysis indicated that the determinant factors have impact on government bond yields. Based on the analysis of the impulse response function (IRF), the yield is to respond to any shocks given by the long term. While through forecast error variance decomposition (FEVD) analysis, found that CDS spreads and oil prices contributed significantly to the movement of Government bond yields.
ABSTRAKProgram Studi (prodi) DIII Teknik Mesin adalah salah satu prodi di Jurusan Teknik Mesin Universitas Negeri Surabaya (Unesa) yang memiliki penjurusan otomotif dan produksi. Jumlah mahasiswa yang masuk di prodi ini setiap tahun berkisar 70 orang dan mereka dibagi dalam dua kelas. Pada akhir semester empat, mereka akan dibagi menjadi dua penjurusan seperti di atas berdasarkan kemampuan akademik dan minat masing-masing mahasiswa. Jumlah dosen tetap yang mengajar dalam prodi ini adalah 10 orang dengan bidang keahlian otomotif, produksi, konversi energi dan sistem manufaktur. Jumlah ini telah memenuhi standar minimal jumlah dosen dalam satu prodi yaitu enam orang. Dari hasil Laporan Kinerja Dosen (LKD) pada periode empat tahun ini didapatkan hasil bahwa Beban Kinerja Dosen (BKD) mengalami kelebihan di atas ketentuan standar BKD yang minimalnya 12 sks (sistem kredit semester) dan maksimalnya 16 sks. Dari ketiga unsur tri dharma yang dinilai yaitu pengajaran, penelitian dan pengabdian masyarakat, ada kenaikan berbeda di setiap unsurnya yang dialami oleh masing-masing dosen sehingga memengaruhi total sks yang diizinkan oleh BKD standar setiap semesternya. Dari hasil yang telah didapatkan, LKD masing-masing dosen mengalami kenaikan di atas rata-rata 12 SKS namun masih terhitung normal. Juga nampak distribusi dosen pada masing-masing prodi kurang merata atau masih banyak dosen mengajar pada prodi yang bukan home base-nya. Sehingga hasil analisis sementara dapat ditarik kesimpulan bahwa masih diperlukan tambahan dosen baru yang berkonsentrasi pada salah satu prodi yang ada di jurusan. Kata Kunci: BKD, LKD, otomotif, produksi, sks. ABSTRACTDIII Mechanical Engineering study program is one of study programs in Mechanical Engineering Department, State University of Surabaya (Unesa) that has automotive and production majors. The number of students who enter in this program are around 70 students per year and they have been divided into two groups. In the end of fourth semester, they will be divided into the majors above which is based on their academic abilities and interests. The number of lecturers who lectured in this program are 10 peoples with the areas of expertise are automotive, production, energy conversion and manufacturing systems. These numbers have been fulfilled minimal numbers of lecturer in a study program that are six peoples. Based on Lecturer Performance Report (LKD) in this four years period, it is obtained that Lecturers Performance Burden (BKD) have increase above BKD provision that has 12 sks (credit transfer system) minimum and 16 sks maximum. From the three elements of Tridharma, that are education, research and community services, there had different increasing in each element that had experienced by each lecturer as of influencing total sks which are allowed by BKD provision per semester. From the results which have been obtained, the LKD on each lecturer goes up on the above 12 sks average but it is still normal. Also it seem that lecturer distribution in each study program did not equal or many lecturers gave lecturing at study program that it is not their home base. Finally the whilst result that can be attracted is the department still needs new lecturer that focus in one of the study programs in the department. Keywords: automotive, BKD, LKD, production, sks.
Research this aim for analyze performance Electrical Submersible Pumps (ESP) Type 95-4 at PDAM Tirta Taman Sari, Madiun City. Method study conducted with Nodal Method. Specification data along with ESP performance obtained directly with method ask answer to operators as well to do experiment by straight away. One ESP components in acquisition capacity fluid is impeller contained in each stage will Keep going give addition pressure and accelerate movement flowing fluid through with style centrifugal. For evaluate operation production could use Analysis Nodal System with connect curve pressure tubing intake stages pump with curve inflow performance relationship. In trial the use type pump ESP 95-4 with power pump (P) 15 kW, discharge (Q) 95 m 3 /h or 0.0263 m 3 /s, rev maximum pump (n) 2900 rpm. Use submersible motor with frequency (F) 50 Hz, power (P) 22 Kw, voltage (V) 380 / 415 V, strong current (I) 47,0/45,3 A, motor rotation (n) 2855-2880 rpm. Then searching for score strong current (I) 3 wires (AI, AII, AIII), time (T), and discharge (Q) with pay attention regulated water pressure through valve butterfly. From result calculation obtained at a pressure of 45 kg/cm 2 get score strong current (I) AI 41.1 A, AII 46.9 A, AIII 44.2 A, time (T) 41.88 s, discharge (Q) 23.87 m 3 /s. It means results from ESP performance still in condition good and still can used.
Crossflow turbines are widely used in small-scale hydropower systems because of their relative flexibility in various heads and discharges, simple design, sturdy construction, and durability. Crossflow turbines work very fundamentally differently from Pelton and Francis turbines, where each crossflow turbine between the blades occurs two times. However, the power produced by the crossflow turbine tends to be low, so the crossflow turbine needs to be developed by adding an interfering blade, with variations in the length ratio of the interfering blades that will be used in this study having values of 0.25, 0.375 and 0.5 with various capacities and loads. The experimental results show that the nuisance blade ratio of 0.375 produces optimal performance in terms of power and efficiency. The highest power produced is 4.461 watts, at a load of 9000 g and a capacity of 18.113 L/s, while the highest efficiency is 96.20%, with a load of 5000 g and at a capacity of 11.024 L/s. Able to utilize the flow of water properly on the main blade and turbine interrupter blades so as to produce a large thrust and able to rotate the turbine with high rpm and large torque.
