Abstract
Turmeric (Curcuma domestica Val) has a bioactive compound namely curcuminoid. It has many pharmacology effects such as anticancer, antidiabetic, antioxidant, hypolipidemic, anti-inflammatory, antimicrobial, antifertility, anti-venom, anti-coagulant, anti-HIV hepatoprotective, nephroprotective, and anticoagulant properties. To increase the economic value of Curcuma domestica Val, it is necessary to develop a hydrothermal extraction process of turmerics active compound. The advantages of hydrothermal extraction were inexpensive, abundant availability, high purity, non toxic, and easy to handle. This research aims to study the effect of operating condition : temperature (130-150oC), time (10-40 minutes) and solid:liquid ratio (1:10 and 1:12) on the bioactive compounds of turmeric extracted from hydrothermal extraction process. Generally, high extraction yield was obtained at higher extraction temperature (140 and 150oC). Under these conditions, with a lower solid : liquid ratio (1:10), high concentration of curcumin is produced. Further, a higher solid : liquid ratio will likely produce the opposite result, except when it operate at low extraction temperature. The high temperature of the pressurized liquid water can reduce the viscosity and surface tension of water so it will increase the diffusion rates and absorption. The higher the solid : liquid ratio, the greater the different concentration beetween interior and exterior cell, which promote the high efficiency of the diffusion process.

Abstract
The incidence of colon cancer in Indonesia reaches 12.8 per 100,000 adults and 9.5 deaths from all cancers. In the other side, colon cancer treatment has many side effects. Therefore it needs to develop colon cancer drugs combined with natural ingredients as co-chemotherapy to increase efficacy and reduce the side effects. One of them is roselle calyx (Hibiscus Sabdariffa L.) which contains the cyanidin-3-sambubioside (flavonoids) and derivatives which are thought to have the ability to inhibit the growth of cancer cells. This study aims to know activity of Rosella CalyxsEthanol Fraction (FEBR) based antioxidant, cytotoxic and molecular docking. The method used are antioxidant study, cytotoxic study with MTT Assay method and in silico study with molecular docking Autodock Vina method. Antioxidant activity of FEBR showed with IC50 value was 428 ug/ml. Cytotoxic potential of FEBR measured against WiDr cell line with IC50 value was 3483 ug/ml. The ability of cyanidin-3-sambubiosida to inhibit IKK and VEGF target proteins with affinity energy was -9.6 kcal / mol and -6.7 kcal / mol using docking molecular with Autodock Vina. Based on the results can be concluded that sianidin-3-sambubioside in FEBR is less potential to be developed as co-chemopreventive in colon cancer.

Abstract
Background: Online game addiction or internet gaming disorder is becoming a serious concern worldwide. The World Health Association (WHO) has classified gaming disorder as a mental health condition, characterized by impaired control over gaming, harmful to an individuals well-being. Cognitive-behavioral therapy (CBT) is a usual therapy for the disorder. Spiritual Emotional Freedom Technique (Spiritual-EFT/ SEFT) therapy, utilizing one-s body meridian points similar to acupuncture, using fingers instead of needles, is recently introduced to treat the disorder. Objective: The pilot study examined the effect of SEFT therapy on gaming disorder. Methods: This was a two-group pretest-posttest quasi-experimental design using a stratified random sampling. Gamers at a private medical school in Yogyakarta, Indonesia, were screened with a previously validated game addiction test. Twenty medical students who met criteria for game addiction were recruited and assigned to intervention and control groups, each consisting of 10 participants. The intervention group received one session of 15-45 minute SEFT therapy conducted by SEFT therapists. Data collected was analyzed using paired t-test and independent t-test. Results: Mean pretest and posttest game addiction test scores in control group were 47.40 and 46.00 respectively, in intervention group were 44.70 and 33.60 respectively. Paired t- test analysis of the scores before and after SEFT therapy in intervention group showed p=0.009 (p<0.05), in control group showed p=0.252 (p>0.05). Independent t-test analysis measuring score changes between both groups showed p=0.007 (p<0.05). Conclusion: SEFT therapy has potentials in reducing game addiction test scores among university student gamers. The findings support testing with a larger sample.

Abstract
Background: Breast milk is a quality food for babies because of its nutrient and immunity content. Proteins found in breast milk are needed to form the bodys tissues that are needed starting from the beginning of a babys life. The high percentage of working mothers who breastfeed is directly proportional to the number of babies who consume milk from dairy mothers. Storage of dairy milk at certain times and temperatures is an unavoidable activity. Three differences were obtained from the research that had been carried out, namely that the storage temperature did not affect the protein content of breast milk, reduced the level of breast milk protein and increased the protein content of breast milk. Researchers want to do a systematic review to get relevant results through reputable journal. Objective: To find out the relevant results regarding the effect of time and storage temperature on protein levels of breast milk. Method: Using systematic reviews through journal reviews on the effect of time and storage temperature on protein levels of breast milk. Elsevier and science direct searches are accessed in the range of 2009 to 2019. All journals are from overseas in English. Results: Systematic review showed that protein levels of breast milk did not change significantly with respect to time and temperature of storage, both the storage temperature (refrigerator) and the temperature of pasteurization.

Abstract
The incidence of tuberculosis in Yogyakarta is 221 cases, 60.18% male and 39.82% women. These conditions are influenced by the lack of adherence to taking medication and carrying capacity of the family. Another problems are the lack of optimal role of health cadres in health promotion and tuberculosis in the community. Cadres are the key to the success of the tuberculosis control program, because cadres have a role as family counselors, finding suspects early, referring to residents and supervisors to swallow drugs for tuberculosis patient directly. The aim of the study was to analyze the influence of tuberculosis prevention counseling on health cadres knowledge and attitudes. The research method is experimental, pre-test and post-test group design.Counseling uses a kit containing posters, videos and leaflets. The kit contains material about the importance of family, adherence to taking medication and nutrition in dealing with tuberculosis. Before and after the intervention, the cadres knowledge and attitudes were measured against tuberculosis prevention efforts with a standardized questionnaire. Data were analyzed to compare with the non-parametric Wilcoxon method test. The number of subjects who fulfilled the inclusion and exclusion criteria were 62 health cadre subjects. The characteristics of the study subjects showed that the highest level of education was high school 36 subjects (58.1%), junior high school 12 subjects (19.4%), elementary school 5 subjects (8.1%) and undergraduate 4 subjects (6.5%). The results showed that there was a significant relationship between counseling using the kit above with knowledge and attitudes towards tuberculosis prevention efforts in the Bantul area of Yogyakarta (p = 0,000). A good level of knowledge is expected to increase the prevention of tuberculosis transmission. In addition, improving the quality of cadres is expected to be an effort to increase knowledge in the community through the provision of communication, information and education by healthy cadres, so that these efforts will reduce the prevalence and incidence of tuberculosis. The conclusion of the study is a significant increase the level of knowledge and attitudes of health cadres in an effort to prevent tuberculosis cases after counseling with poster kits, videos and leaflets about the importance of family, adherence to taking medication and nutrition in dealing with tuberculosis.

Abstract
Anaerobic bacteria in the gingival sulcus is critical for initiation and development of periodontal disease. In addition to periodontal regular procedures, supporting procedure such as irrigation with chlorhexidine or hydrogen peroxide were commonly performed by dental practitioners. Pharmaceutical companies provide several modified irrigating solutions for better efficacy and convenience. However, there are still insufficient evidence for each modification. The purpose of this study is to evaluate the effectiveness in utilizing combined solution of chlorhexidine and hydrogen peroxide toward bacterial growth inhibitory capacity. This research was conducted as an experimental laboratory. The isolated bacteria from human gingival sulcus was taken as a targeted-bacteria. The experiment was performed by using disc-diffusion method on blood agar plate which followed by evaluating the bacterial inhibitory zone. Solutions for the treatment were 0.2% chlorhexidine and 0.2% chlorhexidine combined with 3% hydrogen peroxide. Homogeneity test showed that the data were normally distributed, and the variant analysis showed that the F value was higher than Ft with p<0,05. These results suggested that there was a significant bacterial growth inhibitory capacity among groups. Post-hoc analysis showed that 0.2% chlorhexidine solution gave the higher mean-difference. Therefore, it indicated higher effectiveness in inhibiting anaerobic gingival sulcus bacteria growth capacity.

Abstract
Safe treatments of spent car battery must be conducted because of its Lead (Pb) content that can be a toxic pollutant especially if it gets to drinking water supplies. The objectives of this study is to determine the effects of adsorbent types (zeolite and activated carbon) and concentrations (0%, 5%, 10%, 20%, and 25%) in reducing the Pb-content in waste water from spent car batteries recycling process. Imitated waste water samples was prepared by soaking the contents of a used car battery, such as plates and acid, in four liters of water for ten days, which resulted in an initial Pb-content of 8.02 mg/L and pH of 2. Adsorbents were prepared chemically and physically, and were then added to 100 ml leachate samples followed by stirring at 150 rpm for one hour. The volume of 0.5 M NaOH needed to neutralize the pH was 35.7 ml for 10 ml of waste sample. The lowest final concentration of Pb-content in spent car battery at 0.239 mg/L was achieved by adsorption using 25% activated carbon.

Abstract
There are many researches on welding efficiencies have already been conducted, but very few of them take attention on energy usefulness in workpiece welding zone. Energy usefulness profile can be used as a reference in developing a thermodynamics model to predict post welding material properties and material behavior. The aim of this study is to obtain energy usefulness in AISI 304 welding. The study utilizes finding from previous researches to analyze and calculate the amount of energy received by a workpiece and the energy which is distributed to fusion zone, high temperature heat affected zone, low temperature heat affected zone and unaffected base metal. Metal casting theory approach is required to identify useful work process in welding. AISI 304 post welding energy usefulness profiles are then performed in an energy balance diagram. The present study result shows that energy usefulness decreases when the zone distance form the center of welding increase. The finding has a good agreement with entropy state function theory.

Abstract
This paper is dealing with the evaluation of protection coordination of over current relay and ground fault relay in distribution system. Protection systems that are widely used in distribution systems are over current relays (OCR) and ground fault relays (GFR). The two protection systems are tasked with protecting the distribution transformer against short circuit fault on the distribution network. Given the importance of the protection system in ensuring the continuity of electricity distribution, its performance needs to be evaluated in a certain period of time. Evaluation of the protection system performance includes the time and current settings of the pick-up relay, whether it is in accordance with the IEEE standard. In this study, OCR and GFR performance evaluations were carried out in the Sleman distribution system, Yogyakarta, Indonesia. Relay current settings and pick-up times are evaluated using ETAP software. In this evaluation, the distributed distribution network experiences phase to ground and symmetrical three phases faults. The ETAP evaluation results show that both OCR and GFR relays still work well according to the IEEE standard.

Abstract
Background: Carbamazepine is the first anticonvulsant studied for trigeminal neuralgia. Carbamazepine is often used for indications other than epilepsy. In Indonesia, carbamazepine registered for prophylaxis for lithium-responsive manic depressive disease, antiepilepsy, epilepsy of all types (except petit mal) and trigeminal neuralgia. This study aim is to describe the use of carbamazepine including efficacy and safety, in PKU Muhammadiyah Hospital Yogyakarta. Method: This study was an observational study with retrospective data collection. The method used is cross-sectional. Data was taken from medical records of patients at PKU Muhammadiyah Yogyakarta Hospital who received carbamazepine during 2014. Results: The use of carbamazepine in PKU Muhammadiyah Yogyakarta Hospital during a year was 494 prescriptions given to 117 patients. The physician who most prescribe carbamazepine is a neurologist (63.04%). The most appropriate use of distribution permit was for epilepsy (34.19%), followed by trigeminal neuralgia (6.84%), bipolar (4.27%) and others. The most off-label use is in cases of stroke (7.69%), followed by diabetic neuropathy, herniated nucleus pulposus, cephalgia neuropathy with the same percentage (3.42%) and others. Evidence found in off-label use of carbamazepine was found in DM neuropathic pain and neuropathic stroke pain (24.53%). Conclusion: The use of carbamazepine in PKU Muhammadiyah Yogyakarta hospital is on-label, and some are used off-label. The off-label use of carbamazepine 24.53% has strong evidence, some lack scientific support.

Abstract
Exercise habits is one of the WHO recommendations as a form of non-pharmacological therapy in patients with diabetes mellitus (DM). DM is one of the public health problems in DIY, including in Bantul. Until now not much has been studied so that the purpose of this study was to find out how the description and relationship of exercise habits with hematogram and blood chemistry in DM patients at Jetis Health Center, Bantul. This study was conducted with a cross-sectional design in 99 patients at risk for DM. The inclusion criteria were male or female patients over 18 years old diagnosed with DM or had undergone antiDM drug therapy for 3 months and stated they were willing to study the subject. Interviews were conducted to obtain exercise habits data and hematogram and blood chemistry measurements (GDS, cholesterol and triglycerides) were carried out. Data is presented descriptively and analytically. The mean GDS, cholesterol and triglyceride levels were subjected to a mean difference test with one-way t test with 95% significance. The results showed that the majority of the research subjects were women, basic education, private employment, no smoking, exercise habits, average blood cavern level and fasting were higher than the target, as well as the mean level triglyceride levels. Hb levels, leukocyte count, platelet counts and erythrocytes within normal limits. The cholesterol level of the test subject is also within the normal range. The results showed that the Hb and hematocrit levels of the exercise group were higher than the non-exercise group, but there were no differences in the number of leukocytes, platelets, erythrocytes, sugar levels, cholesterol levels and triglyceride levels. Based on the results of the study it can be concluded that exercise activities are associated with an increase in Hb and hematocrit levels in DM patients at the Jetis Bantul Health Center.

Abstract
The characteristic of natural convection heat transfer in a thermally asymmetric cavity is influenced by temperature differences and space between the heat source and cavity wall. The heat source is any bluff body placed inside the cavity. This research used a heated elliptic tube as the heat source inside the cavity. The three tubes are of 2.5 aspect ratio (AR) in a vertically aligned arrangement. The cavity was thermally asymmetric because three sides of the cavity were insulated while the other side was exposed to convection with ambient air. The clearance ratio (CR) as the ratio between the gap from the insulated wall to the major axis of the tubes to the space of the cavity is varied 0.4 and 0.6. while the pitch ratio is constant at 3.5a. this study analyzes the characteristics of heat transfer from the surface of the elliptical tube to the surrounding air experimentally and numerically. The result reveals that the highest heat transfer coefficient 0f 0.4 CR is higher than that of 0.6 CR. The numerical solution shows the contour and streamlines of the fluid flow in all conditions as the characteristics of natural transfer thermally asymmetric cavity.

Abstract
The experiment on flow pattern of gas-liquid two-phase flow in 45o inclined capillary channel were carried-out. The research was conducted in 1.6 mm inner diameter glass pipe. The range of gas superficial velocity was 0.025 - 66.3 m/s, while that of liquid was 0.033 - 4.935 m/s. The gas fluid was represented by dry air, while that of liquid was glycerol-aqua solution in various percentage, i.e. 0%, 10%, 20%, and 30% indexed by W, GL10, GL20, and GL30, respectively. The addition of glycerin to the liquid phase was intended to vary the liquid viscosities. The high-speed camera was used to capture the two-phase flow. The captured video images were then analyzed to obtain the flow pattern. As a result, it was found that both gas and liquid superficial velocities affect significantly to the two-phase flow pattern observed. Five flow patterns, namely: plug, bubbly, slug-annular, churn, and annular were observed, while the stratified flow was not obtained. On the other hand, the change of liquid viscosity affects to the shift of the transition line between flow patterns in the flow pattern map

Abstract
Pineapple leaf fiber/brass/MgO/epoxy hybrid composites has been fabricated and its tensile properties, hardness and wear rate have been investigated. Whilst the fiber is in the form of short fiber (2 mm long), the brass and MgO are particles. The total volume fraction of the fillers was kept constant at 40% with three different ratios, i.e. 5:3:2, 6:2:2 and 7:1:2. The specimens were individually casted using cold press technique. Tensile properties, hardness and wear rate were evaluated in accordance with the ASTM D 638 type IV, ASTM E10 and Ogoshi method, respectively. Their fracture modes were evaluated by closely observed by means of their SEM photomicrographs and optical micrographs, respectively. The results show that the wear rate, hardness and elastic modulus increase with the increase of pineapple leaf fiber content. The highest wear resistance, hardness and elastic modulus were found being 3.728x10-8 mm2/kg, 20.41 BHN, and 407.34 MPa, respectively, at filler content ratio of 5:3:2. Besides, relatively uniform filler distribution and small amount of voids were also noted from the micrographs being obcerved.

Abstract
Based on World Health Statistics infant mortality rate in the world in 2016 is 41 per 1,000 live births. This value is still quite high if comparing with Sustainable Development Goals (SDGs) at 25 per 1,000 live births. The optimal breastfeeding under two years of age has the greatest potential for survival of all precaution. An effort to prevent infant mortality is by exclusive breastfeeding. Coverage of exclusive breastfeeding in Special Region of Jogjakarta Province in 2017 amounted to 74.9% is still below the national target of 80%. The aim of this research was to find the factors that positively influence to improve coverage of exclusive breastfeeding. The research method used analytic with cross sectional design. The result of the study shows that four factors that positively influence to improve exclusive breastfeeding are mother knowledge, age of maternal, counseling and education, and social support of midwifes. Mother knowledge about breastfeeding related with the provision of exclusive breastfeeding. Knowledge factors have an important role in taking action to give exclusive breastfeeding. Education about breastfeeding is done during pregnancy and during pregnancy visits. Social support of midwifes affect the mother choice to breastfeeding exclusively.

Abstract
Background For the students in Medical School, the end goal after the long battle of studying is to be able to pass the Licensing Test. The undergraduate program of bachelor of medicine requires its students to complete 24 blocks within 4 years. It should be able to foresee the number of failures of that occur during the National Board of Examination test. Aim The aim of this research is to explore the correlation between the results of a students block examination during their four years of study with failure on the licensing test. Method This is a retrospective study. Three cohorts of students (from the classes of 2009, 2010, and 2011) were used in this study. The total students were 335. Failure on the block exam that is referred to in this study is failure during the first attempt of the exam. We analyzed the multiple choice exams (MCQ) of the block and the MCQ of the licensure test. The data was analyzed using MANOVA and Pearson Correlation. Result Students who failed in the licensing test had average 10.1 (sd=3.8) of failed in MCQ block exam. There was a strong, positive correlation between the MCQ score in block exam and MCQ in licensing exam. There was statistically significant difference in block exam score test prior the failure in the licensing test. Conclusion Failure in almost half of the block exams is a bad sign for the future of the students. Medical educationalist should be able to create a predictive learning process item and design an early warning system. Therefore, schools will able to conduct the appropriate procedures regarding the future of the students education during their early stages of study.

Abstract
The nervous system in the body has information to move body parts. This information will be classified to find out what signal information is in the human brain. One developing application is Electroenchephalography (EEG), which is an instrument for capturing these brain signals. Signal patterns can be known from the stimulation a person receives from movements that result from brain activity. In this study, the authors built a system that would classify imagery motor patterns of brain activity through the EEG produced. CSP is used as a feature selection to retrieve patterns from imagery motor signals. Meanwhile, at the classification stage use PSO and SVM. PSO is used because it is more efficient because it requires less computing. Based on the results of calculations carried out it produces a significant accuracy of 93%.
