The problems of this research are: 1) how to develop the approach of societal technology science?; 2) how is the feasibility approach of societal technology science; 3) is the approach of society technology science can cultivate the inspirational attitude?. This is a mixture between qualitatif and quantitative research. Qualitative research was chosen to describe the application of the society technology science. Quantitative research which is a pre-experimental design of one–group Pretest-Postest design, is to see the understanding and change of students’ character before and after the application of the model. The learning model development used the ADDIE (Analysis, Design, Develop, Implemen, Evaluation) design model. The results of this research are: 1) the development of society technology science approach to realize inspiring character was done through 5 stages. With the preliminary stages of approach, establishment/development concept, application in life, the improvement of concept, and assessment; 2) the approach of society technology science to create an inspiring attitude that has been developed, is declared feasible to be used with a score of 15 (90%) in ‘very decent’ criteria; 3) social technology science approach has reflected an inspiring attitude. This is shown from observations on the coursework and results of the student's work that earned an average yield of 3.6 on a ‘good’ category (90%). It is suggested planning a more mature, fuller and wider concept mastery component.

Based Studies were carried out to analyze the internal dose of radiation for workers at Boron Neutron Capture Therapy (BNCT) facility base on Cyclotron 30 MeV with BSA and a room that was actually designed before. This internal dose analyzation included interaction between neutrons and air. The air contained N2 (72%), O2 (20%), Ar (0.93%), CO2, Neon, Kripton, Xenon, Helium and Methane. That internal dose to the worker should be below the dose limit for radiation workers which is an amount of 20 mSv/years. From the particles that are present in the air, only Nitrogen and Argon can change into radioactive element. Nitrogen-14 activated to Carbon-14, Nitrogen-15 activated to Nitrogen-16, and Argon-40 activated to Argon-41. Calculation using tally facility in Monte Carlo N Particle version Extended (MCNPX) program for calculated Neutron flux in the air 3.16x107 Neutron/cm2s. The room design in the cancer facility has a measurement of 200 cm in length, 200 cm in width, and 166.40 cm in height. Neutron flux can be used to calculate the reaction rate which is 80.1x10-2 reaction/cm3s for carbon-14 and 8.75x10-5 reaction/cm3s. The internal dose exposed to the radiation worker is 9.08E-9 µSv.

The purpose of this study is to determine the characteristics of the cooling system on the new design of the Kartini Reactor plate fuel based on numerical calculations (Computational Fluid Dynamics). The fuel plate model was simplified and made in 3D. The model dimensions are 17.3 mm x 68 mm x 900 mm. The space between the two plates called the narrow rectangular channels has a gap of 2 mm. On these simulations a heat flux of 10612,7 watt/m2 was used which was obtained from the MCNP calculation program. Simulations were conducted in a steady state condition and single-phase model laminar flow of an incompressible fluid through the gap between the two fuel plates. This simulation uses UDF (User Define Function) to approach heat flux behaviour that follows the neutron distribution in the reactor core. The simulation results show that the maximum temperature that occur at a flow rate of 0.01 m/s was 43.5 °C.

The implementation of inclusive education in reality, really requires readiness and support from various parties, including fron the educators who are ready in the sense of being able and willing to educate children with special needs. The focus of this study is to examine the perceptions of pre-service teachers in Pelita Harapan University for children with special needs who have access to inclusive education, and what factors underlie these perceptions. The next focus is whether the pre-service teachers have the readiness or vice versa just that there is still doubt or reluctance to teach in inclusive schools. The research method is qualitative descriptive. The number of respondents was one class consisting of 40 students which was a combination of 2 two study programs. The results showed that pre service teachers had perceptions that children with special needs could attend school in inclusive schools, and will be successfull. The arguments that underlie these perceptions are three things: the equal right to education for everyone; curriculumadjustment, teaching methods, assessments and facilities for students with special needs; inclusive schools are a combination of public schools with special schools, and adjustments for each child with special needs in the form of PPI (Individual Development Program). All respondents stated their readiness to teach in inclusive schools. The reason are because a teacher should treat his student equally, the subject of Teaching Student With Special Ability courses has equipped them, and adjustments made in inclusive schools in terms of methods, curriculum, assessment and infrastructure.

Optimized Link State Routing (OLSR)is one of the two standard for mesh networks. OLSR is a link state routing protocol, which use hallo message and topology control (TC) to determine the link state information across the mobile ad-hoc network. OLSR is widely used in the wireless mesh network. Raspberry Pi is a mini computer which can be used as a node router to replace the function of a router in a wireless mesh network. In this research, Raspberry Pi is used as a router nodes to determine the performance of routing protocol OLSR. The parameters used to measure its performance is self-configure time, self-healing and bandwidth usage. The test results showed that the use of routing protocols OLSR on the Raspberry Pi in a wireless mesh network proved able to repair itself if there is a problem on the network since it has ability to self-configure and self-healing.

The development of telecommunications technology continues to increase, especially in the use of cellular communication networks. Users of cellular networks today need high-speed communication to be able to enjoy the facilities offered such as streaming video, web browsing, e-mail and others. With the current increase in user capacity, it causes a lot of interference. Therefore, the use of modulation techniques needs to be considered. To find out the proper use of modulation, in accordance with the conditions of the region and the network used, this study examines the performance of variations in modulation levels, namely QPSK, 16QAM, 64QAM and 256QAM. The parameters measured in this study include RSRP, CINR, BER, user connected and throughput. Based on the coverage by RSRP simulation results, it was found that the RSRP did not change because the power signal will always adjust to any use of the modulation level. For coverage by CINR obtained to obtain a higher rate value, a higher CINR value is needed and for coverage by BER parameters, BER does not affect the bit per symbol carried by each modulation, only affects the different types of modulation. Meanwhile, in the capacity by Throughput parameter, QPSK modulation produces the lowest average throughput value of 14.01 Mbps followed by 16QAM 21.58 Mbps 64QAM 28.6 Mbps and 256QAM 33.87 Mbps. In addition, for the capacity by user connected parameters all connected users on all modulation used will produce 100% for capacity by user connected.

<div class="WordSection1"><p align="center"><em>According to energy observers from the Institute for Essential Services Reform (IESR) the number of electricity consumers in Indonesia has increased by an average of 6-7% annually followed by an increase in the area of its services.</em><em> An increasingly broad network is directly proportional to the potential for interference with the transmission and distribution system. The 150 KV Rembang substations is part of the Java-Bali Interconnection electrical system in northern Central Java that supplies electricity to the Rembang and surrounding areas. Rembang 150 KV substation on May 24, 2019, RBG 01 feeder experienced a disturbance behind the RB1-32 recloser and it was recorded that in 2019 PMT it had been tripped 4 times. Besides, there has been a change in equipment in the form of transformer II. These problems indicate the potential for interference that is not anticipated by the protection system, namely Over Current Relay and recloser.</em><em>  This study evaluates the setting of an outgoing 20 KV OCR protections and recloser on transformer II RBG 01 feeder Rembang 150 KV substation. The scenarios used are calculations with large variations of short-circuit current based on% distance, as well as the calculation of OCR and recloser settings with IEC 60255 standards. Setting currents in the protection equipment is regulated based on current conductivity (KHA) and load current on the recloser. The coordination of the protection settings resulting from this resetting will be compared to the conditions on the ground.  </em><em>Existing (field) OCR outgoing feeder RBG 01 condition TMS OCR value = 0.228 seconds, Iset = 480 A, and t op = 0.3 seconds. The existing OCR recloser condition TMS OCR value = 0.120 seconds and Iset = 400 A. The results of OCR coordinating outgoing feeder RBG 01 obtained TMS OCR value = 0.135 seconds, Iset = 585 A, and t operation = 0.3 seconds. OCR recloser resetting conditions obtained TMS OCR value = 0.10 seconds, Iset = 240 A and t operation = 0.198 seconds. The resetting conditions have met the IEC 60255 standard because recloser working time is smaller than outgoing work time.</em></p></div>
