Salah satu keterampilan yang perlu dikembangkan pada zaman sekarang adalah berpikir kreatif. Kenyataannya, siswa enggan menyampaikan penyelesaian selain yang dicontohkan oleh guru ketika diberi masalah. Salah satu pendekatan yang dirancang dengan melibatkan siswa langsung untuk menyampaikan alternatif-alternatif jawaban dalam menyelesaikan masalah adalah Pendekatan Scientific Berbasis Masalah Open-Ended. Penelitian ini ditujukan untuk (1) mendeskripsikan  kemampuan berpikir kreatif siswa di kelas yang diterapkan pendekatan scientific berbasis masalah open-ended, (2) mendeskripsikan kemampuan berpikir kreatif siswa di kelas yang diterapkan pendekatan scientific, dan (3) menganalisis pengaruh pendekatan scientific terhadap kemampuan berpikir kreatif siswa menggunakan permasalahan open-ended. Penelitian ini menggunakan metode Quasi Experiment Design dengan teknik purposive sampling. Populasi yang digunakan ialah seluruh siswa kelas 8 SMP Negeri 14 Banjarmasin, sedangkan sampel yang diambil adalah siswa kelas VIII-D dan kelas VIII-E sebagai kelas eksperimen dan kelas kontrol. Hasil penelitian yang dianalisis menunjukkan bahwa: (1) Kemampuan berpikir kreatif siswa yang diterapkan pendekatan scientific berbasis masalah open-ended di SMP Negeri 14 Banjarmasin berada pada tingkat cukup kreatif, (2) Kemampuan berpikir kreatif siswa yang diterapkan pendekatan scientific di SMP Negeri 14 Banjarmasin berada pada tingkat kurang kreatif, dan (3) Pendekatan scientific dengan menggu­nakan masalah open-ended berpengaruh terhadap kemampuan berpikir kreatif siswa di Sekolah Menengah Pertama Negeri 14 Banjarmasin. Kata kunci: Kemampuan berpikir kreatif, pendekatan scientific, masalah open-ended. Abstract: One of the skills that needs to be developed today is creative thinking. In fact, students are reluctant to present solutions that were different with the teacher’s examples when they were given problems. One of the approaches designed by involving students directly to present alternative solutions in solving problems is the Open-Ended Scientific Problem-Based Approach. This study aims to (1) describe the students’ creative thinking ability in the classroom that applied an open-ended problem-based scientific approach, (2) describe the students' creative thinking ability in the classroom that were applied a scientific approach, and (3) analyze the influence of scientific approaches to students’ creative thinking ability by using open-ended problems. This research uses Quasi Experiment Design method with purposive sampling technique. The population used was all 8th grade students of SMP Negeri 14 Banjarmasin, while the samples were grade VIII-D and grade VIII-E students as the experimental and the control group respectively. The results of the research show that: (1) students’ creative thinking ability  in the classroom that applied an open-ended problem-based scientific approach in SMP Negeri 14 Banjarmasin were at a sufficiently creative level, (2) the students' creative thinking ability in the classroom that were applied a scientific approach in SMP Negeri 14 Banjarmasin were at a less creative level, and (3) the scientific approach using open-ended problems has an effect on students' creative thinking ability in SMP Negeri 14 Banjarmasin. Keywords: creative thinking abilities, scientific approach, open-ended problems.

Abstract This paper presents an experimental study of wall atomizer usage in flashing purification. The water jet bursts out of the nozzle and hit the wall atomizer, splits into particles and evaporates until it finally condenses. The effectiveness of water particle evaporation influences the condensate volume. In this paper, improvements were more focused on how to generate water particles by applying a wall atomizer in a flashing chamber. The more water particles were created, the better the evaporation and condensation rate. Flashing purification experiments were conducted by following the factorial design method. From the first experiment design, an optimum condensate volume was obtained at a specified folding width of wall atomizer and feedwater pressure; meanwhile, vacuum pressure and feedwater temperature were kept constant. Three different folding widths of 5mm, 8mm and 12mm were tested in this experiment. The second experiments were continued by varying feedwater temperature at an optimum atomizer folding width to obtain more condensate volume. Wall atomizer usage in flashing purification has been proved to increase condensation rate or condensate volume. The highest condensate volume of 150.2ml was obtained from 8mm atomizer folding width with a variable combination of 2.0 bar-g feedwater pressure, a vacuum pressure of −53 cmHg and feedwater temperature of 70 °C. This result was in line with the theory that states that the presence of a wall atomizer increases water particles. There was even an atomizer folding width that provided an optimum condensate volume. The use of an atomizer folding width of less and more than 8mm produced lower condensate volume. At 5mm atomizer folding width, condensate volumes were 24.6ml and 22.0ml, whereas 12mm atomizer folding width produced 48.9ml and 50.3ml.

Specific Speed

A high specific speed centrifugal pump is used in the situation of large flow and low head. Centrifugal pump parameters need to be optimized in order to raise its head and efficiency under off-design conditions. In this study, the orthogonal experiment design method is adopted to optimize the performance of centrifugal pump basing on three parameters, namely, blade outlet width b2, blade outlet angle β2 and blade wrap angle φ. First, the three-dimensional model of the centrifugal pump is established by CFturbo and SolidWorks. Then nine different schemes are designed by using orthogonal table, and numerical simulation is carried out in CFX15.0. The final optimized combination of parameters is b2 = 24 mm, β2 = 24°, φ = 112°. Under the design condition, the head and efficiency of the optimized centrifugal pump are appropriately improved, the increments of which are 0.74 m and 0.48%, respectively. However, the efficiency considerably increases at high flow rates, with an increase of 6.9% at 1.5 Qd. The anti-cavitation performance of the optimized centrifugal pump is also better than the original pump. The results in this paper can provide references for parameter selection (b2, β2, φ) in the centrifugal pump design.
