Abstract
EEG instrument (electroencephalography) is an instrument used as a recorder of brain activity by showing brain waves. The principle of EEG is to detect and to find out changes in each neuron cell that is characterized by waves and interictal waves on the EEG (electroencephalogram) results. Collection of brain signal data is recorded so as to produce imagery motor data. In this study using multiclass EEG signal data (four classes of body movement movements) that will be processed on the EEG signal classification system based on body movement patterns in MxNxT format, where M is the number of channels, N is the number of samples per channel and T is the number of trials. The initial stage of the signal is filtered using butterworth to eliminate noise. EEG signal feature extraction uses the CSP method to get the required features and the last stage uses fuzzy and ANN. The results of the classification of ANN 83% and Fuzzy 78.3%, but in some cases Fuzzy produces significant accuracy.

Abstract
Two main problems of PID Control are determining the parameter gain and incapability of stabilizing higher order system (triple order system or above). The paper will discuss the first problem of PID Control by optimizing the tuning by using a bat algorithm. The advantage of the method is having a converged solution. The objective function in the optimization process is modified to give better performance. The controller design is then tested to control a linearized magnetic levitation system. Based on the simulation result, the method is proven to be able to tune the PID controllers parameters with good consistency in the optimized solution. Also, the optimized system performs well by having rising time and settling time faster than 2 seconds and overshoot not more than 10 percents.

Abstract
This paper presents the power transformer loading analysis in order to improve the reliability of a substation. The substation that was the location of the study was the 150/20 KV Kentungan Substation, Sleman, Yogyakarta Special Region. Power transformers are the most important electrical equipment in a substation. The power transformer functions as a provider of electrical energy that has been transmitted from the power plant to then be channeled to electricity loads. In its operational it is very important to know the capacity and capacity of power transformers in serving electric loads for decades to come, with the aim that the electric power service can take place well. Therefore, the forecasting of the power transformer is important to know in the framework of the operational planning of a good substation. The results of the study indicate that the peak load of power transformers in the period 2014 to 2016 is still in a safe level, where the maximum peak load is 93% of the total capacity of the transformer. However, it is recommended that the power transformer capacity be planned to begin to anticipate the growth of loads in the coming years.

Abstract
Today the communitys needs for rehabilitation materials are quite large, so it needs to be developed to find alternative rehabilitation materials that are good, affordable to the community and capable of replacing lost network structures without causing negative effects. The purpose of this study was to determine the characterization of hydroxyapatite biomaterials from Java sea cuttlefish (Kendal) by XRD testing to be compared with HAp 200 Teihei from Japan. The material for making hydroxyapatite [Ca10 (PO4) 6 (OH) 2] is using two types of cuttlefish (squid and cuttlefish) from the Java Sea (Kendal) which are reacted with a solution of diammonium hydrogen phosphate [(NH4) 2HPO4] in a closed space (pressure vessel) by hydrothermal process using a microwave at a temperature of 200oC for 4 hours. Then to find out the results of the characterization of the test material, the XRD (X-Ray Diffractometer) machine was tested which further indicated that there was similarity with commercially available synthetic hydroxyapatite (HAp 200 Teihei from Japan) as a comparison material. From the analysis of XRD testing that has been done for variations of the type of cuttlefish used, it was found that the peak-peak pattern possessed by CT HAp from cuttlefish is far more dominant to become hydroxyapatite than CT HAp from squid. Meanwhile the CT characterization of HAp from cuttlefish does not completely change to hydroxyapatite, but there is a change to become hydroxyapatite. This is shown by the formation of peak-peak patterns from cuttlefish CT HAp at the peak of 31.801o, 32.178o, and 32.94o which are almost similar to the Teihei HAp 200 from Japan.

Abstract
Increased global energy consumption and CO2 emissions are expected to increase by almost 60% in 2030, compared to the early 2000 (Ghafoor, et al 2014). One of the biggest factors of increasing energy consumption is influenced by the need for water cooling or air conditioning. The need for water cooling/air conditioning is influenced by an increase inthermal loads, as well as an increasingly diverse form and capacity of a building. In addition, the increase in the need for water cooling/air conditioning is also influenced by peoples behavior which requires comfort in the temperature of a building, especially for people who are in tropical climates, for example Indonesia. This behavior becomes a habit, so that today the community is very dependent on the use of air cooling/air conditioning. To answer the problems in the use of water cooling/air conditioner and the utilization of solar energy, the technology of the Solar Air Conditioner is based on the Desiccant Cooler System. In its use, the system is able to cool the temperature in a room as needed, by utilizing solar radiation. The system consists of components Desiccant, Heat Exchanger, Evaporative Cooler, and Solar Thermal Collector, and uses working fluid (water). However, in the application of this system Solar Air Conditioner there is no air exhaust mechanism as a result of cooling in the room, the cooled air is confined indoors so that if left for a long time it will make the air unhealthy. In US Pat. No. 6.513.339 dated February 4, 2003 explained about Solar Air Conditioner in a closed system that uses a desiccant fluid system incooling evaporative cooler, but the system has closed air circulation which causes indoor air quality poor. The innovation that we offer here is in the design of the Solar Thermal Air Conditioner system, there are additional ventilation components that can be controlled, so the system can also function to circulate the air inside the room. In addition, the design function of the Solar Thermal Air Conditioner also emphasizes the saving of electricity consumption, because the largest energy consumption is obtained from thermal energy from sunlight. The result is using components Solar Collector, Heat Exchanger, Desiccant Wheel, and Evaporative Cooler, controlled ventilation, the system is able to condition and circulate air by reducing electricity consumption.

Abstract
Since January, first, 2014 Casemix System has been implemented in Indonesia. Payments for health services of hospitals implemented by National Health Insurance System have used INA-CBGs. INA-CBGs is the Indonesian name of the Casemix system. The change of payment system has significant implications for hospitals, so that they must reformulate their casemix system strategies. The aim of the study is to formulate strategies of casemix system of a private hospital in Yogyakarta by using SWOT Analysis. Data was collected by using structured interviews with director of Human Resource, manager of Human resource, manager of Finance, manager of Nursing of hospital. Combination of total score of Opportunities and Threats and total score of Strengths and Weaknesses can identify a strategic position. Findings of the research showed that strategy for casemix System was combination between Strength (S) and Opportunity (O), namely the use of all strengths of the hospital to gain opportunity from external environment. The result of this research contributes to the hospital preparedness in the face of change to participate in supporting national and World Health Organization policies in achieving Universal Health Coverage by employing more appropriate strategies.

Abstract
End-stage renal disease (ESRD) is one of the public health problems in Indonesia. This study aims to determine the condition of premorbid clinics with the incidence of ESRD. The study design in this study is a case-control with a comparison of cases: the control is equal to 1: 1. Based on the calculation of the sample size of at least 44 patients, the number of volunteers involved in this study was 100 people. The cases were ESRD patients who were determined by the criteria of Pernefri and as controls were patients from the same hospital who were not by the requirements of ESRD Pernefri adjusted for cases based on age and sex. Inclusion criteria of the study sample (1). ESRD sufferers need routine hemodialysis and doctors diagnosis supported by laboratory data; (2). Indonesian citizen; (3). 15-75 years old; (4). Willing to fill out consent information, and (5). Exclusion criteria for the study sample (1). Patients with congenital kidney disease; (2). Have a history of kidney transplants, and (3). Having a mental disorder. We collected secondary demographic data and patient history from medical records. Chi-square analysis with 3x2 or 2x2 tables and the Fishers exact test was used to determine the relationship of clinical conditions or biological conditions and pain history to the incidence of ESRD. The results showed that the clinical requirements of anemia, hyperglycemia, and hypertriglyceridemia were related to the prevalence of ESRD. History of hypertension, diabetes mellitus, dyslipidemia, and family history of ESRD are associated with an increased incidence of ESRD.

Abstract
The cavitation phenomena increase noise and vibration level in a centrifugal pump, which, if not properly maintain leads to catastrophic failure and total stop for the whole production process. It is important to develop a method that can detect cavitation as early as possible. Support vector machine (SVM) is one of pattern recognition techniques which requires statistical features as input for classifier modelling. However, the selection of statistical features is arbitrary, hence further investigation is needed. In this study ten statistical features are extracted from time domain vibration signal and selected using Relief Feature Selection. The vibration signal is taken from cavitation test-rig under four different pump conditions i.e., normal condition, early, medium and full cavitation. The selected features are used as input for two types of SVM, binary and multi class, to classify the new vibration data. Feature selection process reveals that variance, RMS, and SD are the best feature to use for SVM classification. The binary SVM method shows the best plot on early cavitation with accuracy 99% where Bayesian Optimization algorithm with multi class SVM is the best combination to classify all pump conditions with overall accuracy 100%.

Abstract
Hydroxyapatite (Ca10(PO4)6(OH)2: HAp) is widely used as biomaterials. Properties of Kulon Progo hydroxyapatite (KPHAp) derived from local materials Kulon Progo natural gypsum (KPNG) were investigated. Kulon Progo is the name of a district in Yogyakarta Indonesia. KPHAp powder was synthesized from KPNG with diammonium hydrogen phosphate [(NH4)2HPO4] via hydrothermal (microwave) method at 100oC for 30 minutes, then compacted and heated (sintering). The results of this study are as follows. The KPHAp has X-ray diffraction (XRD) and Fourier transforms infrared (FTIR) patterns are similar to HAp SRM 2910 and HAp 200. With increasing temperatures, density and diametral tensile strength (DTS) will increase. The sintering temperature at 1400oC presented the maximum value of density and DTS. The sintering temperature at 800oC and 1400oC presented the multiple phases of calcium phosphate. With increasing compaction value, density will increase, nevertheless DTS will decrease. The results of scanning electron microscopy (SEM) are also used for analyzing the microstructure of samples. From SEM indicated that the real sintering is at the temperature of 1400oC.

Abstract
Indonesian text preprocessing is still very limited and requires tools that can help Indonesian researchers to conduct research in the field of text mining in Indonesian, especially on Twitter. Preprocessing needed for text mining processes such as deleting @ notation; Http; stop words; normalize acronym words, slang words, emoticons; and Indonesian stemming. Gataframework besides providing an OPP-based PHP framework, it also provides text mining preprocessing tools to support those needs. The results of Gataframework text mining preprocessing output can be combined with other tools, one of which is Rapidminer. Gataframework also features a web services API that can be connected with other applications. Since 2018, many studies related to Text Mining have begun to use Gataframework as an alternative tool in the preprocessing stage. The results of the use or quality of this tool are assessed by the Likert evaluation model and the Functionality, Usability, Reliability, Performance, Supportability (FURPS) is known as a model for classifying method which has the parameters Functionality, Usability, Reality, Performance, and Supportability. Based on Gataframework users assessment of 21 respondents, the results were Functionality (87.62%), Usability (85.71%), Reality (85.71%), Performance (80.95%), and Supportability (85.71%) while the average value of the overall parameters was 85.14 %, which means very good.

Abstract
Background: Hospitals are complex and unique entities, they need Hospital Information System (HIS) implementation in order to increase their service quality. HISs acceptance is the important factor for the dissemination of tools and their effectiveness. Purpose: To study the acceptance and obstacles of HISs implementation among healthcare workers Methods: PRISMA guidelines were followed. We conducted searches in online databases such as Pubmed and Medline, written in English and fully accessible by the authors, searched until January 2019. The articles being reviewed are related to health information technology (HIT), clinical information systems (CIS), HIS, electronic medical records (EMR), and computerized physician order entry (CPOE), where the use of most of those applications and technologies is highly integrated. Results: Fifty-one articles were met our inclusion criteria. And it shows that there are many factors that influenced healthcare worker in utilizing HISs, such as human characteristics, and organizational characteristics, there are also behavioral economics concept that affect the application of HISs. Conclusion: Knowing and understanding the acceptance of HISs is important for informatics and healthcare workers because both groups concentrate on acceptance of HISs in the hospital to meet the goal of safe and high-quality patient care. Finally, this study could assist hospital management and IT developers, as well as researchers, to understand the obstacles faced by hospitals in implementing HIS.

Abstract
Patient safety is a very important and fundamental thing in the daily activities of the hospital. This is one measure of the success of a hospital in carrying out its policies so that patients feel safe, comfortable and satisfied. This paper aims to identify determinant factors that influence the patient safety culture at the hospital. The literature search procedure to answer the problem is by searching the library online using the Pubmed search instrument, Cochrane Library, Google Scholar, Google and the relevant text book. The keywords used are "patient safety", "patient safety culture", "hospital", " determinant factors in patient safety culture ", and "patient safety dimensions" using limits, studies conducted at the hospital to hospital employees, publications English and Indonesian. With the search method, initially there were 30 articles, 22 of which met the criteria, published from 2005 until 2018. The results of the analysis from the literature review show that the patient safety culture is influenced by various determinant factors, including perceptions of management, work team support, work stress, job satisfaction towards the patient safety culture in the hospital. These factors were assessed by using some international standardized questionnaires such as the Safety Attitudes Questionnaire (SAQ) and questionnaire from the Agency for Healthcare Research and Quality (AHRQ). Leader factors in hospitals play an important role in the realization of a patient safety culture.
