Harco Leslie Hendric Spits Warnars , Arif Fahrudin , Wiranto Herry Utomo
In the world of student education is an important component where the role of students is as someone who is psychologically ready to receive lessons or other input from the school. However, each student has different performance and development, therefore it is important to do monitoring so that student performance will always be monitored by the school for improving student quality maintenance. Also, in the process of valuing education for students needs to be done by giving an appreciation in the form of giving gifts or just giving words and motivation so that students can perform better in learning and participating in other activities at school. In terms of selecting students with good performance or those who have a very declining development using the school method not only assess students by one criterion but with several criteria to produce a decision that can be accepted by many people. Performance Students must also be monitored by the school or the related rights. In this paper, the student performance prediction was assessed with 5 criteria components and the result shows there are 10 very satisfy students, 10 satisfying students, 10 well students, and 10 Enough students from sample 40 students.

Community mental health nursing training package on body image quality among mental disorders patients

10.11591/ijphs.v9i4.20514
Ibrahim Rahmat , Mohammad Hakimi , Soewadi Soewadi
Mental health disorder could affect the physical, mental, social, and spiritual problems, leading to psychosocial issues such as body-image problem. Body-image is a basic need of human being to fulfill and therefore, the multidisciplinary team; physicians, nurses, and family should have adequate knowledge on the body-image. Increasing knowledge by training the nurses and community health volunteers can be performed to address body-image issues in patients with mental disorders among the community. This study held to identify the effects of community mental health nursing (CMHN) and Self-Concept Assessment Guidelines training on nurse and community health volunteer in increasing the body-image quality of patients with mental disorders. This study used pre and post quasi experimental test with nonequivalent control group design. By comparing the pre-test and post-test scores, nurse’s and community health volunteer’s knowledge were increasing after being given training. Data of body image was collected from 129 patients with mental disorder (treatment group of 69 and control group of 60) as volunteers. After the intervention, treatment group (p= 0.033) and control group (p= 0.075) show that significant increase in the quality of body-image only applies to the treatment group. Providing training on CMHN was effective to improve body-image quality of patients with mental disorders.

Optical repeater for indoor visible light communication using amplify-forward method

10.11591/ijeecs.v20.i3.pp1351-1360
Arsyad Ramadhan Darlis , Lucia Jambola , Lita Lidyawati , Adisty Hanny Asri
In this paper, the implementation of an optical repeater for indoor visible light communication using the amplify-forward method was proposed. In indoor, visible light communication (VLC) can occur by transmitting information signals from lamps as a VLC transmitter toward the VLC receiver as line-of-sight (LOS) that is located with only a few meters. In the non-los (NLOS) communication, the signal will be attenuated, so it needs to amplify to improve good signal quality in a VLC receiver. The optical repeater could be used to improve the signal quality that attenuating due to distance. The audio signal was generated and sent using VLC Transmitter toward the light emitting diode (LED). Then, the electrical signal was converted to become visible light, and it was amplified using an optical amplifier with an amplify-forward method. The signal in the form of visible light that had been amplified would be received by the photodiode (PD), and the VLC receiver processed it. The measurement results showed the system that used the optical repeater could improving the distance until 9.5 m with frequency 6000 Hz, where the best signal quality at a frequency of 3000 Hz. The measurement result showed that the use of repeater components with the amplify-forward method for VLC systems, especially in the room, can increase the range until 4.5 m compare without an optical repeater. This result exceeds the minimum distance of an indoor visible light communication system, with an average distance of the roof to the floor is 3.5 m.

Obesity is a significant public health crisis affecting millions of children globally. The objective of this study was to identify the prevalence and associated factors of overweight/obesity among school children in Kinshasa, Democratic Republic of Congo (DRC). This was a descriptive cross-sectional study among school children and adolescents (n= 1442) from Kinshasa selected using multistage sampling method. A structured questionnaire was used to collect behavioral data. The WHO AnthroPlus was used to calculate BMI (body mass index). SPSS version 21 was used for data analysis. Potential covariates were examined using chi-square tests followed by multivariate logistic regression analyzes The study found that out of 1442 students, 72% of the sample was at a healthy weight, 15% were underweight and nearly 13% were overweight or obese. The prevalence of overweight and obesity was higher in girls as compared with boys. The results of multivariate logistic regressions showed that the gender of children, category of age, percent body fat, eating fruits and vegetables, and physical activity levels were significantly associated with childhood overweight/obesity. One in eight children and adolescents (12.8%) aged 6 to 18 years in Kinshasa going to primary and secondary schools were either overweight or obese.

Courses timetabling based on hill climbing algorithm

10.11591/ijece.v10i6.pp6558-6573
Abdoul Rjoub
In addition to its monotonous nature and excessive time requirements, the manual school timetable scheduling often leads to more than one class being assigned to the same instructor, or more than one instructor being assigned to the same classroom during the same slot time, or even leads to exercise in intentional partialities in favor of a particular group of instructors. In this paper, an automated school timetable scheduling is presented to help overcome the traditional conflicts inherent in the manual scheduling approach. In this approach, hill climbing algorithms have been modified to transact hard and soft constraints. Soft constraints are not easy to be satisfied typically, but hard constraints are obligated. The implementation of this technique has been successfully experimented in different schools with various kinds of side constraints. Results show that the initial solution can be improved by 72% towards the optimal solution within the first 5 seconds and by 50% from the second iteration while the optimal solution will be achieved after 15 iterations ensuring that more than 50% of scientific courses will take place in the early slots time while more than 50% of non-scientific courses will take place during the later time's slots.

Optimized formation control of multi-agent system using PSO algorithm

10.11591/ijeecs.v20.i3.pp1591-1600
Ahmed M. Hasan , Safanah M. Raafat
Formation Control (FC) is an important application for Multi-agent Systems (MASs) in coordinated control and especially for Unmanned Aerial Vehicle (UAV) which are widely used nowadays in military and civil sections. FC is mostly applied in conjunction with consensus algorithm. In this paper, a framework for an implementation of consensus FC that involves the decentralized type of network control is considered in order to achieve  formation keeping, where the control of each vehicle is calculated dependent upon locally existed facts. The dynamic behavior of each vehicle agent is governed by its second-order dynamic model, and the networked mobile vehicle system is modeled by a directed graph. Then, particle swarm optimization (PSO) is implemented for speeding up the convergence to the desired geometrical shape. Acceleration of the network while approaching the coveted shape is achieved and omissions of undesired swing that transpires through the acceleration is examined. The merits and effectiveness of the applied approach are demonstrated using two different examples.

10.11591/ijphs.v9i4.20539
Nur Alvira Pascawati , Tri Baskoro Tunggul Satoto
In an effort to control the COVID-19 outbreak in Indonesia, the government implemented rules such as clean and healthy living behavior by all components of public, isolation, and early detection. Community knowledge, attitudes and practices (KAP) towards COVID-19 play an important role in determining the readiness of the community in accepting policies in the form of behavior change from the health authority. The aim of this study is to determine the KAP toward COVID-19 in Yogyakarta, Indonesia. A cross-sectional online survey of 155 householders was conducted between 04 May 2020 and 18 May 2020. Descriptive statistics, t-tests and one-way analysis of variance were conducted. Most public have understood about causes symptoms, mode transmission, high risk groups, isolation and quarantine, and proper use of disinfectants but people have not been able to distinguish between how to increase immunity and how to prevent COVID-19 transmission. The public has a positive belief that the government will succeed in controlling and managing a health crisis. Public behavior to prevent COVID-19 transmission is good, except the use of disinfectants and stop smoking or prohibiting family members from smoking. Differences in public knowledge, attitudes and practices towards COVID-19 occur in different gender and occupational groups.

Design of arduino-based loading management system to improve continuity of solar power supply

10.11591/ijeecs.v20.i3.pp1677-1684
Muhardika Muhardika , Syafii Syafii
Solar power plants using environmentally friendly technology in the process of harvesting energy from the sun can be a solution to the future electricity crisis so that it has been the most widely developed and reliable alternative. However, the conversion of solar energy depends on the availability and conditions of sunlight. In sunny conditions, the PV system can serve large loads while charging the battery to the maximum. While in cloudy weather conditions or at night, the PV system serves the load and without charge of the battery. The battery will discharge the stored energy until it runs out, and the supply to the load will be cut off before the desired time. Therefore, research on the PV system loading management system is needed to increase the amount of electricity from solar energy and maintain the continuity of electricity supply to the load. The load power management strategy follows the conditions of sunny, cloudy, rainy, or night time by considering the remaining capacity of the battery that can be used. Load installations are designed to consist of low, medium, and high load installations. Simulation results show that the use of PV loading management strategies can increase the operating time of the PV system. When the remaining less than 10% battery capacity and PLN supply is available, the supply will be switched to PLN. The remaining 10% of PV battery capacity could be used to maintain electricity supply to a low load if the PLN supply interrupted. Thus, the use of a loading management strategy will increase the electricity supply from renewable energy and improve the sustainability of electricity supply.

Februati Trimurni , Norma Mansor
The research examined the effectiveness of decentralization program on the healthcare sector at the provincial level in the context of political and administrative decentralization. It adopted qualitative approach and employed the technique of in-depth interview, observation on documentation. Informants consist of public servants, practitioners, community and relevant stakeholders. The implementation of decentralization does not work that ideal for some reason: the devolution and the decentralization programs are not conducted simultaneously, mutually support and complimentary; the lack of local apparatus capabilities to understand and carry out the principles and the practices of the programs in the field; the limitation of financial sources and support to conduct the programs.

Space spraying is still considered as the most powerful method to control the spread of dengue virus transmission, particularly in an emergency such as an outbreak. However, there is still limited information about how the knowledge and perception of people about space spraying against dengue. This study aimed to assess knowledge and community perception of space spraying against dengue in an endemic area. This study was a descriptive cross-sectional study, involved 273 respondents in three endemic areas in Kebumen Regency, Central Java, Indonesia. Structured questionnaires about knowledge and perception of space spraying were administered to the respondents. The 41.4% of respondents had poor knowledge about space spraying, and 42.1% had a negative perspective about space spaying. Only 15.4 % of respondents aware that space spraying applications must be carried out based on several criteria and procedures. Most of them assumed that space spraying can be applied anytime and feel secure when space spraying was applied in their near area. Lack of knowledge and false security on space spraying applications could make people less active to conduct routine practice of mosquito breeding site eradication. It is important to enhance community knowledge and perception of space spraying, so they could understand that space spraying application only for emergencies and routine mosquito breeding site prevention must be carried out regularly.

Arduino based gas leakage and temperature monitoring and control system

10.11591/ijict.v9i3.pp171-178
Adoyi Boniface , A.Y. Nasir , A. M. Hassan
Gas leakage is a major problem with industrial sectors, residential premises and gas powered vehicles like CNG (Compressed Natural Gas) buses etc. One of the preventive methods to stop accidents associated with the gas leakage is to install a gas leakage detection device at vulnerable places. The aim of this project is to develop such a device that can automatically detect and control gas leakages and also monitor temperature in vulnerable areas. The system detects the leakage of the LPG (Liquefied Petroleum Gas) using a gas sensor and then also monitors the temperature using a temperature sensor. When the LPG concentration in the air exceeds a certain level, the gas sensor senses the gas leakage and the output of the sensor goes LOW, the system then opens the exit windows, and then uses the GSM to alert the person about the gas leakage via SMS. Also, when the temperature of the environment exceeds a certain limit, it then turns ON the LED (indicator) and make an alarm through the buzzer. An LCD (16x2) displays the current temperature and gas leakage status in degree Celsius and PPM respectively.
