Published: December 2021

Abstract
The pandemic situation forces the educational system to respond to a variety of issues. During the pandemic, it’s essential to learn more about Technological-Pedagogical-Content-Knowledge (TPACK) and how it can be incorporated into pre-service physics teacher preparation. This qualitative research collects data from ten online teaching videos and ten offline teaching videos of 20 pre-service physics teachers. This study attempts to comprehend the appearance of each TPACK component by analyzing the videos with an observation sheet. The observation sheet explored seven components of TPACK, which are Content Knowledge (CK), Pedagogical Knowledge (PK), Technological Knowledge (TK), Pedagogical and Content Knowledge (PCK), Technological and Content Knowledge (TCK), Technological and Pedagogical Knowledge (TPK), and the last is Technological, Pedagogical and Content Knowledge (TPACK) itself. The result showed that pre-service teachers were determined good TPACK skills, but lacked in certain components. From the result, in both online and offline microteaching, participants rarely showed their TPK. In online activities, it is also seen that participants were faced difficulties in applying their PCK. The different nature of online and offline microteaching drives the need for teacher education institutions to plan and implement microteaching in the pedagogical courses to improve pre-service teachers’ TPACK in both situations.

Abstract
Students’ scientific literacy skills need to be improved because students in the 5.0 society era must have various skills. The availability of relevant student books has limitations in presenting the material. In overcoming this problem, science teaching materials that contain the scientific literacy referred to the 21st-century situation are needed. Therefore, research was conducted on developing integrated science teaching materials with STEM-based Guided Inquiry (STEM-based GI) to improve students’ scientific literacy competence. This study aims to determine the validity of teaching materials (integrated science modules, lesson plans, and learning outcomes tests) for STEM-based GI on the topic of Environmentally Friendly Technology (EFT) products to improve students’ scientific literacy competence. The research and development procedure used was the formative evaluation model. This research procedure was divided into three stages: self-evaluation, prototyping, and evaluation of field tests. However, this research only reached the stage of expert validation (prototyping). The results showed that the average value of the three validators was 94.33% which was included in the very valid category. The coefficient of agreement between validators was (R) 87.10%, included in the high category. Therefore, the resulting teaching material was valid and improved scientific literacy in junior high school science learning.

Authors: Alfatih M F , Hancoyo W 
Published: December 2021

Abstract
On a rocket, control requires monitoring to determine its position and attitude. Rocket stance includes roll, pitch, and yaw angles. Monitoring can be done manually without the help of tools while the object’s position is still within reach. It is difficult to carry out monitoring when the object is moving far and beyond the reach of the operator. This observation requires a monitoring system to monitor the object further. This research applies a telemetry system to a target tracking rocket. The measurement results from the IMU and GPS sensors on the rocket body will be processed by the ATMega 2560 microcontroller and sent via a 2.4 GHz RF signal. to Ground Control Station. The rocket telemetry data that has been sent to the GCS can be viewed by the operator through the GUI system in a computer program using the C# language in Visual Studio. Tests on latitude and longitude are carried out by tracking the trajectory of objects while testing for roll, pitch, and yaw angles is carried out by placing objects according to the reference angle. The results of the position obtained the values of altitude, latitude, and longitude of 0.5364 m, 0.000012°, and 0.000023°, respectively. An attitude tests for roll position, pitch, and compass heading have values of 0.35°, 0.07, and 2.90°, respectively. The telemetry data transmission distance test is still well-received at a distance of 200 with a test speed of 70 KM/hour.

Published: December 2021

Abstract
Some fuzzy time series models have their own advantages and disadvantages. In addition, these models sometimes are complex and claimed to have better forecasting result than each other. The suitable model for forecasting depends on a wide variety of considerations. The models proposed by Chen (1996) applied simplified arithmetic operations and claimed more efficiency than before. The model proposed by Chen was introduced in 1996 and still exists in several previous studies. This research aims to forecast the number of railway passengers in Indonesia using the fuzzy time series. In addition, this research also evaluates the forecasting results based on mean absolute error (MAE) and mean absolute percentage error (MAPE). The results showed the forecasting results in this research has accuracy for 86.6%.

Published: December 2021

Abstract
An anti-icing system has the purpose of protecting the leading edge of the tailplane from contamination during aircraft flight. An anti-icing system in a turboprop aircraft employs heaters that use electrical energy as their power source or heat generated by the bleed air. Protecting the tailplane from contamination is preventing the aircraft stall from occurring that triggers dangerous flight conditions. The aluminum prototype tailplane is assembled with a variable of twisted tape insert and wire coil. The twisted tape insert comes in three different geometries with twist ratio T3 = 9.3; T4 = 7; and T5 = 5.6, as well as a wire coil with fixed geometry. This study shows the best heat transfer rate occurs in T3 with a value of 33.90 W. The consequence of this condition is an decrease in pressure drop that occurs. Twisted 3 has the greatest pressure drop when compared to other geometry, with an average value of 4.72 Pa.

Published: December 2021

Abstract
Information and communication technology development today has provided the latest innovation in didactic world. One of such innovation is the usage of virtual reality (VR) as learning media. The application of virtual reality in learning environment started to be adopted because VR is considered more capable to explain learning material when compared with other learning material. Moreover, learning with VR has the capability for student to learn independently anytime and anywhere. One of VR utilization in learning environment is to use it in a Mini CNC machine assembly simulator. The learning media is meant to be used to improve student skill in assembling a Mini CNC machine independently. This research uses Research and Development method with waterfall model which has several stages which are communication, planning, modelling, construction, and deployment. However, this research only aims up to construction stage, because this research focuses on media functionality test. The media black box research has shown that the media is capable to function as expected.

Indonesia is one of the largest electronic consumer countries in the world. The negative impact unless the increase in the use of electrical energy, there is also an increase in electronic waste or e-waste. If electronic waste (e-waste) is not managed properly, it will cause its own problems, especially environmental health problems. One alternative to overcome these problems is the use of e-waste as a raw material for a series of Waste-Based Energy Saving Lamps, abbreviated as SLHE BBL. This study aims to develop SLHE BBL prototypes base on electric and electronics waste, and test the performance of SLHE BBL prototypes. The SLHE BBL method developed by research and development adapted from Borg & Gall with the following stages: First, needs analysis and product planning; Second: Initial product development, validation and initial product revision.
