Rotary ultrasonic applications are being widely used in machining hard and brittle materials. Conventional conducting ring used as power transmission part limits the ultrasonic applications from rotating at high speed. A high efficiency power transmission system is defined in this article to solve this problem. It consists of a contactless transformer, which was made up of two hollow copper coils, ultrasonic power supply and compensation capacitors. Four compensation methods are proposed and their properties are analyzed through simulations and experiments. The simulations show that S-S compensation is superior to others on the performance of transient and steady circuit parameters and the max transmit efficiency can reach about 97.2% when appropriate compensation method and capacitance are used. Rotary experiments show that speed has little effect on the property of the system.

Food is a basic requirement for human beings. As the population increases, food demand will continue to increase. Food problems in Indonesia are inseparable from rice and flour, in addition to other foodstuffs such as cassava, corn, and sago (Colas, 1994). Efforts to increase rice production are not easy, since there is a massive diversion of agricultural land functions into residential and industrial areas. Indonesia has the potential of tubers as a source of carbohydrates as well as raw materials of local flour. One of the sources of local starch that can be used as flour is canna (Canna edulis Ker). The obstacles faced by smallholders/ small and medium industries (SMEs) who use canna flour that is in the post-harvest process to produce canna flour. Making starch/ canna flour generally still done traditionally, thus affecting the productivity and quality of flour produced. This study aims to design a multi-function canna processing machine to produce canna flour as food. The research method used is the engineering method, which is the activity of designing the build canna processing machine. Canna machine has been successfully made with two main functions namely: the solvent and slicer. The main components of the machine consist of: frame, solvent unit, slicer unit, transmission system, output outlet, wheel, and drive motor. Dimensions of the machine that is 90 cm long, 85 cm wide and 100 cm high. While the frame dimension is 80 cm long, 70 cm wide and 65 cm high. Functional test results show that all components work properly.   Keywords: canna, canna machine, multifunctional, engine design   ABSTRAK   Pangan merupakan kebutuhan pokok bagi manusia. Seiring dengan meningkatnya jumlah penduduk, maka kebutuhan pangan akan terus meningkat. Masalah pangan di Indonesia tidak terlepas dari beras dan terigu, disamping bahan pangan lainnya seperti ubi kayu, jagung, dan sagu (Colas, 1994). Upaya untuk meningkatkan produksi beras bukan hal mudah, karena banyak terjadi pengalihan fungsi lahan pertanian secara massal menjadi area pemukiman dan industri. Indonesia  memiliki  potensi  umbi-umbian sebagai sumber karbohidrat sekaligus bahan baku tepung lokal. Salah satu tanaman sumber pati lokal yang dapat dijadikan tepung adalah ganyong (Canna edulis Ker). Kendala yang dihadapi oleh petani atau Industri Kecil Menengah (IKM) yang memanfaatkan tepung ganyong adalah pada proses pasca panen untuk menghasilkan tepung ganyong. Pembuatan pati atau tepung ganyong umumnya masih dikerjakan secara tradisional, sehingga mempengaruhi produktivitas serta kualitas tepung yang dihasilkan. Penelitian ini bertujuan untuk merancang bangun mesin pengolah ganyong multi fungsi sehingga dihasilkan tepung ganyong sebagai bahan pangan. Metode penelitian yang digunakan adalah metode rekayasa, yaitu kegiatan merancang bangun mesin pengolah ganyong.

The Right

In the company PT. Headquarters of Tunas Utama produces quite a lot of waste so that there needs to be a treatment to accelerate the waste processing. The problem is how to make the waste can be processed quickly so that it can be processed to be included in the production process so that there is no buildup of waste. Planning an agitator asbestos waste mixer machine, where the equipment or machine serves to accommodate the middle waste before entering into the mixing process and stirring continuously to avoid sedimentation. In this final project, the right type of agitator will be selected for the waste mixing process, then count the existing engine elements such as the type of mixer, motor, transmission, and shaft. So that it can produce the right mixer. From the results of the calculation of the mixer using a motor with a power of 0.5 HP with a reducer of 1:30, the transmission system uses a v-belt and a pulley with a drive pulley diameter of 129 mm and a driven pulley diameter of 200 mm, resulting in a rotation of 30 rpm. For the stirrer, using a paddle stirrer with a drive shaft diameter of 50 mm.Keyword : Machine element, Planning,Waste, Agitator Didalam perusahaan PT Djabes Tunas Utama menghasilkan waste yang cukup banyak sehingga perlu adanya penanganan untuk mempercepat proses pengolahan waste tersebut. Permasalahannya adalah bagaimana cara agar waste tersebut dapat diolah dengan cepat sehingga dapat diproses untuk dimasukkan pada  proses produksi sehingga tidak terjadi penumpukan waste. Maka dari itu perlu adanya mesin pengaduk untuk mengaduk middle waste tadi agar tidak terjadi pengendapan. Dan mesin pengaduk tersebut banyak macamnya.  Dan akan direncanakan sebuah mesin pengaduk waste asbes jenis agitator, dimana peralatan atau mesin ini berfungsi untuk menampung middle waste sebelum masuk ke proses mixing dan dilakukan pengadukan secara terus menerus untuk menghindari pengendapan. Pada tugas akhir ini akan dipilih jenis agitator yang tepat untuk proses pengadukan waste tersebut, kemudian menghitung elemen-elemen mesin yang ada seperti jenis pengaduk, motor, transmisi, dan poros. Sehingga dapat menghasilkan mesin pengaduk yang tepat. Dari hasil perhitungan mesin pengaduk tersebut menggunakan motor dengan daya sebesar 0,5 HP dengan reducer 1:30, sistem transmisi menggunakan v-belt dan pulley dengan ukuran diameter pulley penggerak sebesar 129 mm dan diameter pulley yang digerakkan sebesar 200 mm, sehingga menghasilkan putaran sebesar 30 rpm. Untuk pengaduknya menggunakan jenis pengaduk paddle   dengan diameter poros penggerak sebesar 50 mm.Kata kunci : Elemen  mesin, Perencanaan, Waste, Mesin pengaduk (agitator)

Yumoto and Dmochowski (Cancer Res.27, 2098 (1967)) reported the presence of mature and immature type C leukemia virus particles in leukemic organs and tissues such as lymph nodes, spleen, thymus, liver, and kidneys of SJL/J strain mice with Hodgki's-like disease or reticulum cell neoplasm (type B). In an attempt to ascertain the possibility that this neoplasia may be of viral origin, experiments with induction and transmission of this neoplasm were carried out using cell-free extracts of leukemic organs from an SJL/J strain mouse with spontaneous disease.It has been possible to induce the disease in low-leukemia BALB/c and C3HZB strain mice and serially transfer the neoplasia by cell-free extracts of leukemic organs of these mice. Histological examination revealed the neoplasia to be of either reticulum cell-type A or type B. Serial transfer is now in its fifth passage. In addition leukemic spleen from another SJL/J strain mouse with spontaneous reticulum cell neoplasm (type A) was set up in tissue culture and is now in its 141st serial passage in vitro. Preliminary results indicate that cell-free material of 39th tissue culture passage can reproduce neoplasia in BALB/c mice.

Using immune electron microscopy Feinstone et. al. demonstrated the presence of a 27 nm virus-like particle in acute-phase stools of patients with viral hepatitis, type A, These hepatitis A antigen (HA Ag) particles were aggregated by convalescent serum from patients with type A hepatitis but not by pre-infection serum. Subsequently Dienstag et. al. and Maynard et. al. produced acute hepatitis in chimpanzees by inoculation with human stool containing HA Ag. During the early acute disease, virus like particles antigenically, morphologically and biophysically identical to the human HA Ag particle were found in chimpanzee stool. Recently Hilleman et. al. have described similar particles in liver and serum of marmosets infected with hepatitis A virus (HAV). We have investigated liver, bile and stool from chimpanzees and marmosets experimentally infected with HAV. In an initial study, a chimpanzee (no.785) inoculated with HA Ag-containing stool developed elevated liver enzymes 21 days after exposure.

Immunoperoxidase Labeling

Recently, periodate-lysine-paraformaldehyde (PLP) fixation was reported for immunoelectron microscopy (1). In PLP fixation, carbohydrates are oxidized by periodate and cross-linked by lysine; paraformaldehyde stabilizes proteins and lipids. By using PLP fixation, intracytoplasmic type A viral antigens have been previously demonstrated by immunoperoxidase labeling (2). In the present study, PLP fixation has been applied for the detection of the same antigens in mouse mammary tumor culture cells by both immunoferritin and immunoperoxidase methods. Rabbit anti-intracytoplasmic type A virus serum (anti-A), kindly provided by Dr. M. Muller (3), rabbit anti-strain A mouse mammary tumor virus (anti-MMTV) and preimmune rabbit serum as control were used to detect viral antigens in cells of C3H/HeJ strain mouse mammary tumor culture. Attempts have been also made to demonstrate peroxidase labeling of type C virus particles in frozen sections of an SD-MSV-induced NZB rat bone tumor tissue by rabbit anti-MuLV serum.
