Abstract

Penelitian ini tentang pemanfaatan tenaga surya untuk pemanas udara lewat penggunaan sebuah kolektor energi surya berbentuk pelat datar (Type T-39) yang dikombinasikan dengan pipa-pipa saluran pertukaran panas pada sebuah ruang pertukaran panas. Hal ini bertujuan untuk memperoleh hubungan antara efisiensi kolektor () sebagai fungsi temperatur air rata-rata (Tavg) dan kecepatan aliran air (V).Kolektor energi surya ini dirancang menjadi sebuah tipe kolektor yang tidak dapat digerakkan namun dapat berfungsi dengan baik sebagai pemanas air. Proses pemanasan alat ini menggunakan dua media yaitu pemanas udara dan air. Alat ini bekerja lewat variasi kecepatan air yang mengalir di dalam kolektor dan dengan memperhitungkan kecepatan udara yang melalui pipa-pipa saluran pertukaran panas yang berhubungan dengan kolektor tersebut, maka kondisi optimum proses pemanasan udara dapat diindikasi pada jarak-jarak tertentu antara tabung-tabung bilik pertukaran panas.Hasil penelitian ini menunjukkan bahwa waktu efektif pemanasan berlangsung mulai dua jam sebelum tengah hari hingga dua jam sesudahnya. Untuk pemanasan udara, sebuah persamaan umum efisiensi kolektor diperoleh melalui hubungan antara temperatur air rata-rata yang mengalir di dalam kolektor (Tavg) dan kecepatan air (V), yaitu  = 115,3336403 (Tavg)-0,097124 (V)-0,102206Persamaan diatas mempunyai kesalahan standar sebesar 0,2375%, dan berlaku pada kisaran temperatur (Tavg) sebesar 15,86 oC hingga 31,48 oC, dan pada kecepatan aliran sebesar 0,47 liter per 60 detik hingga 0,600 liter per 60 detik. Berdasarkan kondisi-kondisi operasi terapan tersebut, jumlah total transfer panas bertambah sejalan dengan berkurangnya kecepatan air di dalam kolektor yang dihubungkan dengan pipa-pipa saluran pertukaran panas. Kata kunci: tenaga surya, kolektor, pelat datar, udara, saluran pertukaran panas

Abstract

Bomb is an object with high destructive power. Today the bomb threat in Indonesia are common. Research earlier bomb squad robot has a weakness in the design of wireless communication and video viewer. This study tries to design a prototype robot bomb disposal by using IP cameras and wireless communication using a WIZnet based microcontroller interface ATMega8535. Video is displayed with MJPEG viewer designed using Visual Basic. The movement of the robot is set using the buttons on the monitoring software that is integrated with MJPEG viewer. From the test results obtained prototype robot can move in accordance with the existing arrangements on the monitoring system by using MJPEG as robot navigation. Robots also managed to pick up objects using a gripper simulated bomb and put it into a simulated bombing. In this study used camera is a camera that is found on android phone because of limited funds. The future can use the integrated camera with IP addressing

Abstract

In operation, the bridge structure is subjected to load variation both in the form of static load and dynamic load in variation of load intensity and frequency. In bridge structures made of steel structures, dynamic loading conditions can cause loosening of bolts, cracks and even structural failures. This paper describes the method of determining the damping bridge constant (c) by the logarithmic decrement calculation method of the vibration data generated by the impulse load. Furthermore the damping constant is used to calculate the vibration response equation of the structure along with the mass constant (m) and the stiffness of the structure (k). The mass constants are obtained by measurement whereas the stiffness constant of the structure is obtained by FEM modeling for open and closed structure models. The results of the analysis will be used to interpret the pattern of failed structures in the development of the diagnostic system. The calculation of damping constant for open and closed model is 0.07556 and 0.12513, while mass and stiffness constant for closed and open model model is 18 kg and 9 kg and 9523809.524 N / m and 183486.2 N / m for stiffness constant.

Abstract

Penelitian ini bertujuan untuk mengetahui produksi biohidrogen dari limbah sagu hampas di Indonesia terutama pada perlakuan pretreatment asam encer. Sampah sagu tersebut dihasilkan dari industri rumahan yang menghasilkan bubuk tapioka dari log Arengapinnata. Perlakuan pretreatment asam encer dilakukan dengan menggunakan asam sulfat (H2SO4) pada konsentrasi 0,27,3, dan 0,6 M dengan berbagai periode waktu paparan 30, 60 dan 90 menit. Setelah menyelesaikan pretreatment tersebut, sagu mengangkut limbah padat kemudian mengalami fermentasi gelap ar 30, 1 atm dan pH awal 5.0. Hasilnya menunjukkan bahwa total hasil gas berada pada kisaran 1 - 4 ml / g VS. Konsentrasi H2 meningkat secara signifikan pada maksimum 27,7% v. Hasil ini menunjukkan bahwa limbah sagu di Indonesia berpotensi menjadi sumber energi terbarukan biohidrogen.
