Abstract

ABSTRActToday, urban kampungs  are inhabited by most of the Indonesia’s population. The high  density of population and building is one of the most common conditions found in urban kampungs, whichimpact on various problemsexperienced by the inhabitans. One of those impacts isthe lack of children's interaction area. Thisphenomenon needs to be studied in depth, since social interaction plays  important role for the child's personal development in the future. Thisstudy, which is part of the author's dissertation research, aims to explore the physical settings variation  of children interaction space in the urban kampungs. This research uses explorative method, meanwhile  data collecting uses field observation method. Kampung Ngampilan Yogyakarta was taken as the case, because it has high density and specific geographical condition due to its location on the river bank. As a result, it is found that with limited environmental conditions, the children interaction space in Kampung Ngampilan Yogyakarta is formed organically or unplanned. The spaces can be grouped into three kinds of categories, namely based on the degree of enclosureness, degree of fixation of space elements and the degree of naturaleness of space elements. This finding can be used  as  reference in kampung  development which is more conducive as place for children interaction activities.Keywords:children interaction space,physical setting, urban kampung ABSTRAKSaat ini kampung kota merupakan permukiman yang dihuni oleh sebagian besar peduduk kota di Indonesia.  Kepadatan penduduk dan bangunan yang tinggi, merupakan salah satu kondisi yang sering ditemukan di kampung-kampung kota. Anak-anak, sebagai salah satu kelompok penduduk, ikut merasakan dampaknya, salah satunya adalah karena semakin minimnya area interaksi anak-anak. Hal ini perlu untuk dikaji secara mendalam, mengingat interaksi sosial di usia anak berperan penting bagi perkembangan pribadi anak ke depan. Kajian yang merupakan bagian dari riset disertasi penulis ini, bertujuan untuk menggali keragaman seting fisik ruang interaksi anak di kampung padat kota semacam itu.  Riset ini menggunakan metode eksploratif, dengan menggunakan metode observasi lapangan untuk menggali data. Kampung Ngampilan Yogyakarta dipilih sebagai kasuskarena densitasnya tinggi, rerata ekonomi penduduknya menengah ke bawah, dan kondisi geografis  yang spesifik karena berada di berada di bantaran sungai. Dari hasil kajian ditemukan bahwa dengan kondisi lingkungan yang terbatas, ruang interaksi anak di Kampung Ngampilan Yogyakarta terbentuk secara organik atau tidak terencana. Ruang-ruang tersebut dapat dikelompokkan menjadi tiga macam kategori, yaitu berdasarkan derajat keterlingkupan, derajat fiksasi elemen ruang dan derajat kealamiahan elemen ruang.  Temuan ini diharapkan dapat menjadi salah satu referensi dalam pengembangan kampung kota ke depan, yang lebih kondusif sebagai wadah aktivitas anak-anak sebagai salah satu kelompok penghuninya.Kata kunci: ruang interaksi  anak, seting fisik, kampung kota

Abstract

Kendaraan listrik sebagian besar menyimpan energi ke dalam baterai dikarenakan baterai memiliki kapasitas penyimpanan energi yang besar namun memiliki kepadatan daya yang kecil. Selain itu, baterai memiliki kelemahan usia pakai yang terbatas dan harga yang relatif mahal. Karakteristik drive cycle pada kendaraan listrik seringkali tidak konstan karena disebabkan proses charge-discharge berlebih sehingga mengakibatkan penurunan usia baterai. Penambahan superkapasitor sebagai media penyimpanan energi dapat mengatasi keterbatasan pemenuhan energi oleh baterai. Oleh karena itu dibutuhkan metode pembagian suplai daya pada sumber energi hibrid baterai dan superkapasitor dengan menggunakan fuzzy logic controller (FLC) untuk mendapatkan pembagian yang optimum. Penelitian ini dilakukan dengan menggunakan simulasi pembagian suplai daya pada penyimpan energi hibrid baterai dan superkapasitor kendaraan listrik menggunakan FLC ketika kondisi normal, starting, dan pengereman. Parameter utama yang diperhatikan adalah kecepatan, arus, dan daya. Komponen-komponen pada kendaraan listrik meliputi baterai, superkapasitor, inverter 3 fasa, motor BLDC, dan driver motor (speed control) sebagai pengatur kecepatan dan mendukung adanya pengereman regeneratif. Simulasi tiap komponen dilakukan menggunakan perangkat lunak MATLAB simulink 2018b. Dari hasil pengujian FLC dapat membagi besarnya arus dan daya yang harus disuplai oleh baterai dan superkapasitor. Selain itu superkapasitor dapat menerima lonjakan arus dan daya. Dengan pengaturan tersebut diharapkan pembagian daya dapat dicapai nilai optimumnya.

Abstract

Current technology is increasingly developing, one of which is inverter control for high-speed train traction motor drives. Currently, the train driver is an AC electric motor. Inverters typically operate in the high-speed region. In this paper, it aims to drive the speed rotation of a 3-phase AC motor. The inverter is used to control the rotational speed of the motor, the vector control provides control of the speed and torque of the motor load for the 3 phase ac motor running at high speed. The vector control design is with the Arduino microcontroller program. The design of the inverter is in the form of a module that contains several components, namely IC drivers, resistors, mosfets, capacitors. The results of the PWM inverter were obtained in a waveform with a voltage of 4.72 volts, a frequency of 224.0 Hz and a duty cycle of 33.3%. The results of this study show the variation of the rotational speed of the motorcycle, the rotational speed of the motor with a value of 360 RPM the load torque response shows a value of 72.8 Nm, to the rotational speed of the motor of 960 RPM, the load torque response shows a value of 19.6 Nm. Based on the results of the inverter control research on motor torque control with the vector control method, the load torque response is able to follow the variation in the speed of rotation of the motor. The higher the rotational speed of the motorcycle, the lower the load torque respons.

Abstract

Exploration of ocean current energy allows for the development of turbines as the primary conversion device. Turbine technologies have been developed in various types, including bio-inspired turbines, such as the humpback whale fluke turbine. In this study, the achievement of a humpback whale fluke turbine is investigated by applying various forms of foil, both symmetric and asymmetric, to obtain the appropriate foil profile. Symmetric foils were represented by NACA 0012, NACA 0018, and NACA 0021, while asymmetric foils were represented by NACA 4312, NACA 4512, and NACA 4712 foils. Simulations were performed using QBlade software, which was developed based on the DMST theory. In general, symmetric foils have a more stable performance than asymmetric foils because they produce a better performance at positive and negative angles of attack. This result is also supported by a review of efficiency and self-starting capability where symmetric foils have significantly higher CP values and positive CQ along the azimuth angle than asymmetric foils. Finally, NACA 0021 foil is recommended for a humpback whale fluke turbine based on its efficiency and self-starting capability.

Abstract

An improved design of the conveyor system of Arjuna 1.0 electron accelerator for 3D object irradiation has been done. The penetration of low energy electrons is less than 1 cm in the surface, causing a challenge for the irradiation process for sterilization of 3D objects. We design a conveyor that can be rotated 360o to irradiate objects evenly. The dimension of this conveyor is 1750 x 600 x 800 mm and the maximum diameter of the object is 7 cm. Based on the Frame Bending Stress analysis to calculate the strength of the conveyor frame, it is shown that the maximum displacement is only 0.029 mm, which is very small so it will cause no disturbance to power transfer from the motor to the conveyor. The normal stress (Smax) is 3.926 MPa and the bending stress for Smax (Mx) and Smax (My), are 2.391 MPa and 3.925 MPa respectively. We also calculate the stress analysis of the 3 mm-thickness of the motor mount and found that the Von-Misses Stress, first, and third Principal Stress are 4.425 MPa, 5.01 MPa, and 1.95 MPa respectively. These results confirm that the design and the material used for the conveyor are safe because the stress is very low than the material’s yield strength which is 207 MPa. The power needed for this conveyor is 0.01724 kW, with a maximum speed is 880 rpm. The new model of 3D conveyor has been constructed and can be implemented to ARJUNA 1.0 to irradiate objects on all its surfaces
