Publisher : Universitas Sanata Dharma

This paper presents the results of the motion therapy device Continuous Passive Motion (CPM) Machine which is applied to the shoulder joint with storage movement. The process of joint rehabilitation is carried out by continuous passive movements. This movement is intended not to overload the work of the muscles and there is no stiffness in the joints after surgery or stroke patients or patients who have carried out immobilization for quite a long time. The CPM Machine developed can move flexion and horizontal abduction. The position storage in this tool is carried out in a range of movements in flexion and horizontal abduction. So that with the storage of movement can be done movement / therapy exercises in patients with joint stiffness passively and continuously.

The current problem of solar energy water distillation is in its low efficiency. Low efficiency is caused by inefficient water evaporation processes. Increasing the efficiency of water evaporation is done by controlling the rate of water entering into the absorber. The commonly used mechanical control system still has weaknesses such as the instability of the water entering the absorber. This causes less effective evaporation of water so that the resulting distillation efficiency is not optimal. The water rate input system for distillation in this study is based on a simple microcontroller. The microcontroller-based input water rate control system allows the rate of input water with a small but continuous flow rate so that the water evaporation process can be more effective. This study aims to improve the efficiency of solar energy water distillation by increasing the efficiency of the water evaporation process through controlling the flow rate of water inlet. The research was carried out by the experimental method. The parameters varied were: the rate of input water which was 0.3 l / hour, 0.5 l / hour and 1.2 l / hour. Parameters measured in this study were: (1) temperature of absorber, (2) temperature of the cover glass , (3) temperature of cooling water, (4) input water temperature, (5) ambient air temperature, (6) distilled water results, (7) solar energy coming in and (8) time of recording data. The results showed that the production of distillation water using microcontroller-based water rate control was a maximum of 523% compared to the model without water rate control at a water flow rate of 0.3 liters / hour, with distillation efficiency of 66%. From the results of this study it can also be concluded that microcontroller based water flow rate controller is more stable than mechanical water flow controller, especially in small flow

Measuring privacy leakage in term of Shannon entropy Aditya, Ricky; Skoric, Boris

Differential privacy is a privacy scheme in which a database is modified such that each user?s personal data are protected without affecting significantly the characteristics of the whole data. Example of such mechanism is Randomized Aggregatable Privacy-Preserving Ordinal Response (RAPPOR). Later it is found that the interpretations of privacy, accuracy and utility parameters in differential privacy are not totally clear. Therefore in this article an alternative definition of privacy aspect are proposed, where they are measured in term of Shannon entropy. Here Shannon entropy can be interpreted as number of binary questions an aggregator needs to ask in order to learn information from a modified database. Then privacy leakage of a differentially private mechanism is defined as mutual information between original distribution of an attribute in a database and its modified version. Furthermore, some simulations using the MATLAB software for special cases in RAPPOR are also presented to show that this alternative definition does make sense.

Publisher : Universitas Sanata Dharma

The design of cashew nut or cashew nut sheller uses appropriate or low technology with consideration of low cost for tool material. This pengkacip tool will be used at Ngudi Koyo, Imogiri, Bantul, Yogyakarta. Cashew shell peeler or cippling device as a result of the design is a modification of the existing cashew shell peeler. Some parts of the existing tool are applied to several modified parts, namely the lever mechanism, picking knife, or lever knife. This paper will discuss the method of selecting a suppressor, lever and picking system on a tool using the morphological map analysis method. Morphological maps will produce alternative designs for cashew nut peeler. The selection of alternative designs will be carried out by analyzing the results of testing in a technical mechanism, material strength, and alternative design quality values. Testing of alternative technical systems mechanisms is done by comparing the mechanical systems of existing tools. The size of the tool uses the anthropometric measurements of the female operator's body, because the operators in the Ngudi Koyo UKM are all women. The tool size adjustment will provide work comfort and increase efficiency. Quality testing in addition to using standard anthropometric standards, will be tested for quality of ease of care, ease of transferring, clean, neat, simple and safe tool.Key words: Effective technology , low technology tool, security, Design Alternative Testing

International Journal of Applied Sciences and Smart Technologies Volume 01, Issue 02, December 2019
Publisher : Universitas Sanata Dharma

This paper discusses about synthesizing a state-feedback controller for a quadcopter based on an optimal linear quadratic control method. The resulting flight control system enables the quadcopter to maintain stability and to track a reference input. The solution to this control problem involves solving an algebraic Riccati equation. The reference-input tracking capability is simulated to show the capability of the quadcopter flight control system.

Design and Development of a Path-Tracking System Based on Radio Frequency Identification Sensor for Educational Toy Robot (EDOT) Wicaksono, Martinus Bagus
International Journal of Applied Sciences and Smart Technologies Volume 01, Issue 02, December 2019
Publisher : Universitas Sanata Dharma

This paper offers the design and development of a path-tracking system based on Radio Frequency Identification (RFID) sensors. This Path-tracking system will be used as a navigation system on EDOT. The EDOT requires a navigation system because it must be able to drive from the starting point to the predetermined end point automatically. This path-tracking system uses RFID sensors to detect RFID cards which have been arranged as a path. And then the EDOT will pass through the path consisting of some RFId cards. EDOT is a solution of a previous system, called Line-Follower, which uses infrared as a sensor to detect lines to guide a robot to go towards its destination point. The path-tracking system used by EDOT can work more efficiently in detecting the path to be traversed than other robots using the line follower system with infrared sensors or LDR (Light Dependent Resistor).Keywords: path-tracking, RFID, EDOT, robot

Environmental pollution is increasing every year. From 2011 to 2014, environmental pollution in the Special Region of Yogyakarta increased above 250 percent. The effect of environmental pollution is the decreasing availability of clean water. Universitas Sanata Dharma as an institution engaged in the field of Education seeks to provide clean water where clean water is suitable for drinking, namely with RO (Reverse Osmosis) technology. Drinking water distribution has run well in the Universitas Sanata Dharma, but it lacks hygiene. In this study, researchers Designing Independent Automatic Drinking Water Platforms that could distribute clean water ready to drink students with a certain dose. The result of this study is that an independent automatic drinking water platform can provide 200cc of clean water ready for drinking in 9 seconds each time a user (student) uses this tool.
