Abstract

The problem of increasing energy demand must be balanced with energy production. The development of water-powered energy is one alternative solution for the sustainability of life on earth. The Savonius Hydrokinetic Turbine is a type of hydroelectric power plant that can convert kinetic energy into electrical energy. River currents as a renewable energy source can rotate the turbine and convert it into electricity through a generator. This study aims to determine the effect of a 180˚ twist change on the Savonius Tornado Helical Hydrokinetic Turbine with a variation of the lower end plate smaller than the upper end plate. The research method was carried out by testing 4 turbine variations, namely the Savonius Hydrokinetic Turbine and the Savonius Tornado Helical Hydrokinetic Turbine D / 2, 3D / 4 and 4D / 4, where D is the diameter of the turbine end plate. The testing process was carried out in an open prismatic channel with variations in flow speed of 0.331 m / s, 0.396 m / s and 0.486 m / s. The results of the study showed that the Savonius Hydrokinetic Turbine produced a Cp (Coefficient of power) value of 0.114 - 0.226 and a TSR (Tip Speed ​​Ratio) of 1.550 - 1.775. The performance of the Savonius Tornado Helical Hydrokinetic Turbine with end plate D / 2 was significantly higher than the Savonius Hydrokinetic Turbine, with an increase in Cp value of 11% and TSR of 12.6%. The Savonius Tornado Helical Hydrokinetic Turbine with end plate 3D / 4 increased the Cp and TSR values ​​by 6.6% and 10%. While the Savonius Tornado Helical Hydrokinetic Turbine with end plate 4D / 4 was able to increase the Cp value by 0.4% and TSR by 2.4%.

Abstract

Water is a variety of needs in everyday life. Raw water in Palangka Raya City is still influenced by peat water which has a low pH, while river water has quite high turbidity due to sedimentation. For residential areas that are far from the reach of PDAM, it will be difficult to get clean water and there is no fast technology to handle the decrease in acidity. An alternative innovation that can be used by people who are far from the reach of PDAM is to use appropriate technology tools for wasp nest water purifiers. The purpose of the study was to obtain a comparison of water treatment results from several variations of non-natural filter media in wasp nest water purifiers against pH and TDS. The method used in this experimental test was to test short, medium, and high wasp nest water purifiers with a filtration hole size of 0.25 cm and a distance between holes of 0.5 cm. The volume of non-natural filter media in various sizes of wasp nest water purifiers was conditioned the same in each experiment. The filtration process uses 4 pumps with a pump discharge of 45 l/minute each. The results obtained indicate that the filtration type water purifier functions well and is able to increase pH. There is an increase in the TDS parameter because during the water circulation process there is uncontrolled mixing of the filter media.

Abstract

Savonius Tornado Hydrokinetic Turbine has an optimal capture area, but is less able to transmit the thrust of water kinetic energy into electrical energy. The purpose of this study is to analyze the Savonius Tornado Hydrokinetic Turbine twisted without an end plate. The experimental method was carried out on the flume channel to compare the performance between the Conventional Savonius Hydrokinetic Turbine and the Savonius Tornado Turbine without an end plate by twisting the turbine blades 1/2D, 1/3D, 4/4D, where D is the width of the turbine end plate. This test will obtain the Coefficient of power (Cp), RPM, torque (τ) and TSR as parameters to see the turbine performance. This experimental study used a flow velocity (v) between 0.322 m/s - 0.507 m/s. The results of the study indicate that the Conventional Savonius Turbine produces a torque value of 0.040 Nm - 0.095 Nm, the 1/2D Savonius Tornado turbine without a twisted end plate produces a torque value of 0.051 Nm - 0.194 Nm, the 3/4D Savonius Tornado turbine without a twisted end plate produces a torque value of 0.049 Nm - 0.155 Nm, and the 4/4D Savonius Tornado turbine without a twisted end plate produces a torque value of 0.044 Nm - 0.168 Nm. The Savonius Tornado Hydrokinetic Turbine is twisted without end plates, resulting in increased turbine performance

Abstract

Kecepatan aliran bidang vertikal di lahan gambut memiliki karakteristik unik dan berbeda dengan sungai, yang dipengaruhi oleh topografi, morfologi, dan hidrometri saluran. Penelitian ini bertujuan untuk menganalisis profil distribusi kecepatan aliran bidang vertikal dan kecepatan aliran rerata yang dilakukan pada 2 saluran dengan variasi lebar dan kedalaman. Pengukuran kecepatan dilakukan pada potongan melintang yang dibagi menjadi 7 rai (B/2, B/4, B/8, B/16) pada kiri dan kanan serta tengah, dimana (B) adalah lebar saluran. Pada setiap rai, kecepatan diukur pada sepuluh titik kedalaman dengan pengulangan 5 hingga 16 kali. Hasilnya menunjukkan pola distribusi kecepatan yang sama pada beberapa rai di kedua saluran, khususnya (B/2 di tengah, B/4 kiri, B/8 kiri, B/4 kanan, dan B/8 kanan). Pada rai ini, kecepatan besar di permukaan dan menurun mendekati dasar. Namun, di tepi saluran 1 (B/16 kiri, B/8 kanan), saluran 2 (B/16 kanan), pola distribusi menunjukkan kecepatan aliran bertambah besar di dasar saluran. Rerata kecepatan aliran mencapai 0,041 m/dt di saluran 1 (B/16 kanan) dan 0,048 m/dt di saluran 2 (B/2 tengah), dengan kedalaman rerata 0,4 sampai 0,6 h. Hal ini disebabkan pada lahan gambut terdapat akar dan serat, membentuk pori-pori yang mempercepat pergerakan aliran air tanah menuju saluran khususnya bagian tepi.

Abstract

Sarang Tawon water purifier uses filtration principle which is done repeatedly through certain filter media that are arranged in layers. The water quality as the filtration result is influenced by the filtration system and the type of filter media used and the duration of purifying process. The factor of thickness and filter media density were neglected until causing problem in the duration of water purifying process. This research aimed to find out the influence of thickness difference and filter media density of Sarang Tawon water purifier towards the parameter of Total Dissolved Solids (TDS) and pH. The experimental method was applied by testing the thickness of zeolite stone filter media combination, ginger coral, and coconut fiber from the Sarang Tawon water purifier with radius 4R/3, R, and 2R/3 where R=3 inches. The density variations of coconut fiber filter media were 20%, 40%, 60%, 80% and 100%. The research results showed that the thickness of filter media in Sarang Tawon water purifier tool with radius 4R/3 with coconut fiber filter media density was 80% owning the ability to increase the highest pH value. There was increase of TDS parameter in each trial caused by the dissolved of ginger coral filter media, but it did not show significant number. TDS parameter resulted by the tool with radius 2R/3 with density variation of coconut fiber filter media amounted 80% showed a relatively stable value.

Abstract

Energi terbarukan bisa digunakan sebagai solusi mengurangi ketergantungan pada bahan bakar fosil dengan cara menggunakan sumber hidroelektrik seperti penggunaan turbin vertikal berjenis Darrieus. Turbin Darrieus memiliki kelemahan yaitu kesulitan memulai awal putaran (self starting) pada rotornya karena berbasis gaya angkat. Studi ini menyelidiki pengaruh penambahan pengarah Omni Directional Guide Vanes (ODGV) dengan jumlah guide vanes dan besar sudut berbeda-beda terhadap turbin Darrieus dengan tujuan dapat menekan kelemahannya. Studi ini menggunakan turbin Darrieus 2 (dua) airfoil dan 3 (tiga) airfoil dengan profil NACA 0012 untuk diujikan di aliran air pada saluran prismatik. Hasil uji eksperimental menunjukkan bahwa penggunaan pengarah dengan perbandingan 1/6 celah ODGV (6 guide vanes) dan sudut 0 º mengakibatkan bertambahnya nilai Coefficient of Power  (Cp) dan nilai Tip Speed Ratio (TSR), sehingga mampu meningkatkan Cp rata-rata lebih besar 34,25% dari turbin Darrieus konvensional. Namun seiring bertambahnya jumlah guide vanes dan besar sudut membuat performa turbin menurun. Pengarah ODGV mampu meningkatkan nilai TSR sehingga dapat mengoptimalkan gaya angkat pada turbin.
