Abstract
Interferon-gamma (IFN-γ) is one of the central cytokines in the anti-carcinogenesis immune response. Lymphocytes are one of the IFN-y producing cells. Black cumin seeds (BCS) have an active content of thymoquinone and unsaturated fatty acids with biological activity as immunomodulators. This study aimed to determine the effect of administration of BCS extract on IFN-y secretion activity by SD rat lymphocytes induced by dimethylbenzanthracene (DMBA). In vivo experimental study on DMBA-induced SD rats. BCS extract was given with three doses for two weeks before being induced and five weeks during DMBA induction. IFN-y levels in lymphocyte culture supernatants were determined by the ELISA method. The difference in IFN-y levels between groups was analyzed by ANOVA test, the significance of 95%. The results showed that administration of BJH extract for 14 days did not affect cellular composition toward the edge of the test animal. BCS extract can increase IFN-y secretion activity by DMBA-induced SD rat lymphocytes.

Keywords

Abstract
Fun School Movement / Gerakan Sekolah Menyenangkan (GSM) is a grassroots social movement carried out with teachers, aimed at creating a pleasant learning culture atmosphere and make students become more critical, independent and creative in school. This movement promotes and builds the awareness of teachers, principals and education policy makers to build schools as a pleasant place to learn science and provision of life skills so that children become a successful learners. Blockchain is a new technology that is widely used by various fields as a work concept and thought that is included in the system or framework of the system or movement that is built. The Blockchain was originally used as a thought used in cryptocurrency, one of which was used in Bitcoin. This technology is increasingly ogled by many engineers because of the ability of this technology to be able to change everyones view of a technology that is currently centralized and also very dependent on an institution. The blockchain for social movements is used as a concept to channel an idea and idea about the form of a pleasant school. The selection of blockchain as a suitable concept for social movements is because there are similarities in the goals of this social movement. The Fun School Movement is not a social movement assisted by the government, this social movement is purely carried out by the two founders who saw their children very happy and also enjoyed studying while stepping on Primary Schools in Australia. Through these experiences the two founders wanted to apply what happened to their childrens school in Australia and of course adapted to the social conditions in Indonesia.

Abstract
Background: Bloodstream infections (BSIs) are a potentially life-threatening health care–associated infection (HAI). Catheter-associated bloodstream infections (CABSIs) are the main threat to patient safety presented by suboptimal vascular access care. We conducted a literature review in knowing how CABSI Surveillance in Hemodialysis Patients. Method: Literature review is conducted by looking for articles from 2008 to 2018 using a database from PubMed. Articles are accepted in this study if they examine surveillance infection, CABSI, BSI, and hemodialysis. Sorting articles through abstracts and free full text articles. Results: A total of 32 articles about BSI, 20 articles included inclusion criteria. In the United Kingdom, these infections account for 10%-20% of all hospital-acquired infections. The mortality rate from CABSIs is reported to range from 12%-25%. The relative risk for CABSIs associated to the use of central vascular catheters (CVCs) is 64 times greater than to peripheral vascular catheters, presenting therefore CVCs as the main source of CABSIs. The Centers for Disease Control and Prevention (CDC) reports that CRBSI rates have remained steady in hemodialysis patients over the last decade, with an estimated 37,000 CRBSIs occurring in 2008. Many journal mentioned that hemodialysis central venous catheter (CVC) use and they contribute to increased infection-related hospitalization, mortality, and health care costs. Risk factors for infection include catheter-dwell time, access site, multi-lumen catheters, the patient-s underlying conditions, as well as catheter care practices. Conclusion: Collaborating with patients to develop optimal interventions that increase catheter-related education and self-efficacy cannot be overemphasized. The true incidence of BSI is not known. Information such as prevalence, duration of catheter insertion, and dressing management are insufficient because of a lack of surveillance data. Further research is still needed on surveillance of bloodstream infections.

Abstract
Telecommunications technology continues to grow every year because the need for communication that is used by the community to support life needs in terms of the use of information is increasing. The process of transmitting information through a channel will not be separated from obstacles in the form of errors. One of the transmission technologies is modulation. Modulation is the process of laying on information from the modulation signal to the carrier (the high frequency) by varying the carrier signal according to the modulation signal. One parameter that determines the quality of digital modulation is the Bit Error Rate (BER) by looking at the effect of the energy value per bit of the power spectral density ratio (Eb / N0) and signal to noise ratio (SNR). The purpose of the research can be a reference for the comparison between modulations in the implementation of the fifth generation (5G) technology and can be developed in further research, so that the benefits generated can maximize the implementation of 5G technology. Data collection in this study uses two scenarios, namely Additive White Gaussian Noise and Frequency-flat Rayleigh Fading channels. In each scenario using modulation that is different from the modulation of BPSK, QPSK and 16-QAM. After the simulation results using Matlab are obtained, these results will be compared with the BER theory of each modulation.

Abstract
Some organizations have implemented Green IT to reduce the negative impact of IT devices. The framework for measuring the implementation of Green IT that much used is the G-Readiness framework. In Indonesia, there is a local framework called the ZEN framework. This study focused on analyzing the comparison between the G-Readiness framework and the ZEN framework. There are several parameter approaches that are used to compare two frameworks such as regulations, device periods, data center design, power management, recycling, vendor procurement, etc. Data collection method uses a literature review, questionnaire, and directly analyzes comparisons between frameworks. The conclusion of this study is that each framework has its own advantages and disadvantages, where the comparison shows that the G-Readiness framework and the ZEN framework have no difference. Generally, the difference only in the completeness of the aspects that include it. Furthermore, the ZEN framework is more specifically used for universities, while the G-readiness framework can be used for various organizations.

Abstract
Pharmaceutical research has successfully incorporated a wealth of molecular modeling methods, within a variety of drug discovery programs, to study of biological and chemical systems. The integration of computational and experimental strategies has been of great value in the identification and development of novel promising compounds. Broadly used in modern drug design, molecular docking methods explore the ligand conformations adopted within the binding sites of molecular targets. This approach also estimates the ligand-receptor binding free energy by evaluating critical phenomena involved in the intermolecular recognition process. Today, as a variety of docking algorithms are available, an understanding of the advantages and limitations of each method is of fundamental importance in the development of effective strategies and the generation of relevant results. The purpose of this review is to examine current molecular docking strategies used in drug discovery and medicinal chemistry, exploring the advances in the field and the role played by the integration of structure- and ligand-based methods in cancer disease. Cancer is still a major health problem in the world because of its high morbidity and mortality. Among the cancers that attack humans, breast cancer is the most prevalent cancer among women in the United States with 182,460 new cases (26% of cancer-fighting women) in 2008. We have performed a comparative assessment of two programs for molecular docking: PLANTS and AutoDock Vina 3.0. This was accomplished using two different studies: RMSD score and docking experiments against 6 different proteins (cyclin D1, cyclin E, p53, HER-2, EGFR, VEGF) which are specific proteins target in cancer research. The docking accuracy of the methods was judged based on the corresponding docking score. The results from experiments showed that Autodock Vina 3.0 has more appropriate than PLANTS method. A speed comparison demonstrated that Autodock Vina was faster than PLANTS among the tested docking programs. The Autodock Vina could perform all the RMSD score < 2.0 A for 6 target proteins, and PLANTS only showed 2 of 6 that has RMSD score < 2.0 A. We can conclude that Autodock Vina more effective than PLANTS method for molecular docking in cancer drug discovery.

Abstract
Nowadays computer networks are widely used to exchange important and confidential data information between servers to computer or cellular devices. Access to user control and use of software or hardware as a firewall often experience security problems. Unauthorized access to information through computer networks continues to occur and tends to increase. This study examines the attack detection mechanism by using three data mining algorithms based on particle swarm optimization (PSO), namely PSO-K Nearest Neighbor, PSO-Random Forest, and PSO-Decission Tree in the Canadian Institute for Cybersecurity Dataset (CICIDS2017). The initial experiment showed that the approach using the PSO-RF method was able to produce the highest accuracy of attack detection. Accuracy values generated using the PSO-RF algorithm with a combination of number of trees and maximal depth = 20 in the CICIDS2017 dataset are intact higher than other proposed algorithms. The highest accuracy of attack detection in the CICIDS2017 dataset is intact, which is 99.76%. In the CICIDS2017 dataset 50% Benign and 50% Attack it turns out that the PSO-RF algorithm with a combination of number of trees and maximal depth = 20 also gets the highest accuracy value of 99.67%.

Abstract
Banyumas that located in Central Java is one of the regions in Indonesia with great tourism potential. There are lot of tourism destinations in there, such as Baturraden, Small World, Andang Pangrenan, The Village, Caping Park, and many more. Unfortunately, there are no public transportation facilities to go there. Public transportation for the tourism is the main facilities for visitors. It plays an essential role in city tourism development. The important thing to do before building a public transportation is to determine the optimal route. Scientific contributions are needed to develop it. One of the fields of study about it is graph theory. It is a branch of discrete mathematics. It is usually use in modeling of phenomena in real life. In transportation it is most commonly used to study problems. The aim of this paper is to provide the optimal public transportation route for the tourism in Banyumas. We have used Dijkstra and Floyd algorithm in order to compare the performance of optimal public transportation routes.

Abstract
The purpose of this study is to determine the effect of circle holes on the strength of the unidirectional rectangular composite and then compared with metal material (isotropic). This is considering that a construction generally requires holes for bolts and rivets when certain parts will be connected to other parts. The samples are the unidirectional rectangular fibers reinforcement polyester composite with variations in two types of circle holes namely one circle in the middle (model 1) and three circles with details of a larger circle in the middle and two circles are beside along the longitudinal (model 2), three types of fiber directions (0o, 45o, and 90o) with three variations of fiber content. For comparison, the metal here is steel with a variety of model 1 and model 2. From tensile testing results the nominal strength of model 2 both composite and steel is greater than model 1. For the composites, the maximum nominal tensile strength occurs at 0o fiber angle then decreases at 45o, then minimum at 90o, and the greater fiber content will make the greater of nominal tensile strength. The finite element formulation is carried out by using the analysis section of the ANSYS package.

Abstract
This paper reports the effect of composite oil on the breakdown voltage. The composite oil is combined of palm oil and diala-b oil with various ratios. The breakdown voltage testing scheme is carried out with two variations test, the first without treatment and the second using treatment (boiling). Tests are carried out to obtain a breakdown voltage that is in accordance with the minimum standards of liquid insulators. From the test results, the breakdown voltage of the sample before going through the treatment process is very low, between 12-18.8 kV / 2.5. After the treatment process, there is a good breakdown voltage test, which is between 30-35 kV / 2.5 mm. The breakdown voltage test results in the treatment sample are higher as the concentration of the mixture from the diala-b increases. The average increase is 0.05 kV / 1% mixed diala-b. Palm oil samples have a higher water content than diala-b, which is 0.10%, while the diala-b is 0.08%. The effect of water content on the breakdown voltage average of 0.01 kV / 0.02% moisture content. Acidity (pH) in the test sample between 5.32 - 5.58. The 100% diala-b oil sample is 5.32 and 100% palm oil is 5.58. From the pH level, it is known that the higher the PH, the lower the breakdown voltage in the sample oil. The effect of an increase in pH on decreasing breakdown voltage is an average of 0.1 / 0.192 kV. The results show that the water content and acidity affect the oil breakdown voltage. The breakdown voltage values of all oil mixture samples that have undergone a treatment process have met the IEC standard No.56 1991s with results classified as above the standard (standard >= 30kV / 2.5mm).

Abstract
The market place industry in Indonesia has increasingly stretched in recent years. The main stages to achieve success in the business of buying and selling at market place identify the factors that influence consumers when buying goods offered by the market place. These research aims to analyse consumer behaviour in the selection of market places. This study uses a model of the Unified Theory of Acceptance and Use of Technology (UTAUT-2) approach and and the Partial Least Square Structural Equation Modelling (PLS-SEM) method. The UTAUT-2 model will describe the factors that influence consumer behaviour in the choice of market place and PLS-SEM used to test hypotheses from the researches that have been made with the research data obtained from the questionnaire. Respondents were expected to fill the questionnaire in this study as many as 200 respondents. The expected results of the thesis are the emergence of the most influential factors on consumer behaviour in the choice of market place so that it can be used as a recommendation for creating a new market place and improving the system on an existing market place.

Abstract
Activities in the oil and gas industry have some impacts on environment through flare gas. Flare gas occurs as the combustion products of natural gas are wasted into atmosphere without further and proper treatment. These products increase carbon dioxide (CO2) and greenhouse gas (GHG) emissions which are considered as the biggest contributors to global warming. Indonesia has participated in accelerating the reduction of gas flares in oil and gas activities through the Zero Routine Flaring by 2030 initiated by the World Bank. In 2017, the volume of flare gas in Indonesia was approximately 82 MMSCFD. The object of this study is flare gas in Pertamina RU III Plaju Palembang which has three flare stacks and produces about 0.84 MMSCFD of flare gas . The flare gas, consist of hydrocarbon components (mostly butane, propane and pentane) of high economic value if it is conserved and processed further. Using Gas to Liquid (GTL) method, flare gas can be converted into Liquefied Petroleum Gas (LPG) which is of valuable use domestically. The simulation was performed using ASPEN HYSYS with three distillations and one cooler. Simulation of the separation of LPG from the flare gas unit of the Crude Distillation Gas Plant (CDGP) of 1051 barrel/day can produce propane 34.67 barrel/day, i-butane 148.98 barrel/day and n-butane 159.06 barrel/day.

Abstract
Dental arch form and dimension are fundamental factors in orthodontic diagnosis and treatment planning. Its dimension will increase due to the eruption of teeth and also affected by ethnicity, nutrition, systemic disease, hormonal factors, and gender. There are many teeth erupt in 8-10 years old children. The aim of this study was to assess the correlation between age and dental arch dimension of Javanese children in good nutritional status for consideration of orthodontic treatment. This was a cross-sectional study with 66 children aged 8 to 10 years in normal dentoskeletal relationship, grouped based on the age as the subject. Each group consisted of 22 pairs of dental study model, male and female. Anterior and posterior size of dental arch length were measured by digital sliding calipers from midpoint between right and left permanent central incisors perpendicular to intercanines and intermolars. The width were measured at intercanines and intermolars. Pearson-s correlation test showed that there were significant correlations between age and maxillary dental arch lengths (p=0.01, r=0.310 for anterior and p=0.043, r=0.249 for posterior). Based on this study, it can be concluded that there was a correlation between age and dental arch length of 8 - 10 years old Javanese children in good nutritional status.

Abstract
The adequacy of a persons iodine is usually assessed by the level of urine iodine. However, the level of urine iodine has not been able to describe the levels of fT4 and TSH. This study was to determine the relationship of blood iodine levels with fT4 and TSH serum level of children aged less than 2 years in endemic areas of IDD. Blood iodine level was measured using Ammonium Persulfat Dry Digestion method and fT4 and TSH using ELISA method in 50 children under the age of 2 years in Ngargosari Samigaluh Village. Spearman correlation test was used for statistical analysis. There were 44 children (88%) with blood iodine levels 52 until109 μg / L, having a mean fT4 of 1,638 more or less 0,163 ng / dL and a mean TSH of 2,619 more or less 2,982 mIU / L. Subjects with a blood iodine level of less than 52 μg / L totaled 4 children (8%) with a mean fT4 of 1,605 more or less 0,161 ng / dL and a mean TSH level of 1,865 more or less 1.17 mIU / L. Subjects with blood iodine were more than 109 μg / L totaling 2 children (4%) with a mean fT4 level of 1.69 +0.084 ng / dL and a mean TSH level of 4.16 more or less 0.82 mIU / L. The blood iodine content of children in Ngargosari Samigaluh Village did not significantly correlate with fT4 hormone levels (p = 0.7690) or TSH (p = 0.287)

Abstract
The implementation of package payment system for healthcare in Indonesia, or INA CBGs, as part of the National Health Security program, has been a focus of scrutinized studies. Indeed, for any private hospital, profit has been served as the main focus in supporting its operational. On the other hand, the prevalence of non-communicable diseases such as diabetes with the wide range of possible complications, has proven to be costly. Therefore, to maintain the sustainability of its service, private hospitals have to put the more efficient and effective cost management system into place, especially in the existence of INA CBGs. Objectives: objectives of this study is to predict the development of complication and the rate of medication cost among the member of JKN in one diabetes outpatient department in a hospital in Yogyakarta. Methods: The study using bivariate analysis to shows the correlation between complications and medication cost and medication, and using Multiple Discriminant Analysis to predict diabetes complications in future. Result: The results showed the complication rate has positively influenced the medication cost delivered by the hospital. Furthermore, the increased number of complications has led to the increased number of medication utilization which in turn has raised hospital-s operational cost: The Multiple Discriminant Analysis has successfully showed the prediction of diabetes complications with accuracy rate of prediction classification of 62.2%. . Therefore, it is regarded as essential to increase additional cost to cover the complication. Conclusion: The finding show that a more preventive measure program should be a key to prevent further complication which in turn would generate more profit.

Abstract
Background: Bantul X Hospital is one of hospital that has a hemodialysis unit that is currently in the development stage. In its development, the hemodialysis unit has not been spared by several obstacles, one of which is related to costs. Therefore, it needs to be done carefully and effectively so that the hospital continues to obtain benefits and does not lose. The results of the analysis with the Activity Based Costing method are expected to be used to manage unit costs, become a reference in tariff determination decisions and manage human resource management in the most effective way possible. Metode: The type of research is descriptive method research with a quantitative approach. The unit cost analysis method uses the ABC (Activity Based Costing) modification method by Baker. Result: Based on the results of calculations using the ABC method, the unit cost of single-use hemodialysis is Rp. 992.531 and unit cost of re-use hemodialysis is Rp. 834.036. Unit cost of hemodialysis using ABC method is lower than the tariff of Bantul X Hospital, which is Rp. 1,188,000 and higher than the claim of INA CBGs is Rp. 825,500. Conclusion: There is a negative gap between the unit cost of the single-use and re-use hemodialysis using ABC method with the claim of INA-CBGs. Therefore, the hospital needs to evaluate unit cost further for cost effectiveness.
