Humanoid Soccer Robot is one of the divisions in the Robocup Competition. Robocup is an organization that focuses on research and development of soccer robots. With the aim to build a robot soccer team that will be able to fight humans in 2050. In humanoid robots, the main problem in developing humanoid robots is how to make humanoid robots run stably on uneven surfaces. This paper describes how to maintain the stability of the humanoid football robot called EROS, by optimizing walking movements. Optimization is done by adjusting the movement of walking to the footing conditions. The default robot position will be adjusted based on the position of the robot's center of pressure (CoP), which is then combined with the Linear Inverted Pendulum Model (LIPM). To find out the condition of the pedestal base, the pressure sensor is mounted on the sole of the robot's feet. So it is known the position of the pressure center on the robot, which will be used as a parameter in planning the walking motion. This system has been implemented on humanoid robots with a height of 520 mm, as well as running on synthetic grass under different conditions at a constant speed. From the experiments that have been done it can be seen that by applying this method makes the robot more stable when it is on an uneven surface.

In the natural disaster areas, a cellular-based telecommunication system is often disrupted. Handy-Talky is a power full as an ad-hoc telecommunication system for this condition. This equipment works in the Very High Frequency (VHF) and Ultra High Frequency (UHF). The VHF band is strongly influenced by the environment where is this system implemented. This system is suitable for short-range terrestrial communication. However, to develop a very long-range communication, it needs an HF type of communication system. In this study, a transverter system was built to convert the frequency signal from VHF to HF and vice versa. The transverter system was implemented on Raspberry Pi and supported by the C programming language. Two identified processes were the transverter process of converting HF signal to VHF/UHF signal and the transverter process of converting VHF/UHF signal to HF signal. The HF gateway device was controlled by VOX mode in order for it to transmit immediately when receiving voice signal from VHF/UHF gateway. The communications between these two devices with different frequency run in half-duplex mode. The voice activity detection technique was employed to replace the user, automatically activated the HT push-to-talk radio power for the threshold value of 60 dB in SNR. The calibration was conducted on EEPIS campus. The HF transceivers were positioned in D3 building and Post-Graduate building, EEPIS. It has shown that the communication process using the transverter was successful.

Interest in parallel computing has been increasing since the introduction of multi-core processor at a reasonable price for the common people, moreover parallel computing has the advantage of faster processing time compared to serial computing. However, the use of parallel computing which can shorten the time does not make it free from the risk of failure which causes the parallel computing process to stop so that the time needed to complete the process will increase depending on how long it takes to detect the failure (realize that the process is stalled) and repair the system to run the process again, also the process time that has been spent because of repeating the process from the beginning. To deal with this, a new resilience system is implemented for parallel computing with the adoption of RaaS (Resilience as a Service). In RaaS-implemented system, checkpoint is done periodically and RaaS run monitoring in order to detect failures. If failure occurs, RaaS automatically run recovery mechanism by replacing the failed instance and resuming the process from the most recent checkpoint. The experiment shows that RaaS implementation can be done for parallel computing and there is faster processing time to handle failure. With the implementation of RaaS, the time to detect failure is shorter and there is no need to repeat the process from the beginning again.

Public display is a media that is increasingly being used every day. No longer just a medium for advertising. But it has also begun to be used in non-commercial institutions such as education and government. One potential use of public display is as a medium of public information to increase awareness of disasters. One of the problems faced by public displays is the relatively small level of community adoption. This can be seen when compared to mobile phones, there is no large usage level. The use of public displays still tends to be incidental, not yet a daily necessity such as a mobile phone. In this study, a chat-based interaction is designed to let the user interact with the public display using their mobile phone. The interaction is designed to allow users to post content on public display using their mobile phones. The usability measurement results show the possibility of the interest of the community about the interaction model. Hopefully, in the future, this could push the use of a public display as an information medium to improve disaster awareness.

Wheeled Indonesian Soccer Robot Contest (Wheeled KRSBI) is a national competition focused on the development of wheeled soccer robots. EEPIS Robot Soccer On Wheeled (ERSOW) is one of KRSBI's wheeled soccer robots. ERSOW has Artificial Intelligent (AI) for detecting balls, dribbling, and avoiding opponents. Currently, the object detection system in ERSOW uses image processing, this will be a heavy computation because it is done thoroughly in all pixel area. This research focused on making local detection to reduce heavy image processing. Local detection works by searching for local objects in the area around the detected object. It creates the ROI for local detection. From the results of tests conducted when the ball is detected, local detection system can increase 4 EPS from the full frame detection system, whereas in the test results when the ball is not detected, the local detection system is 0.2 FPS slower than the full frame detection system.

In recent years, the automotive industry has seen rapid growth in autonomous vehicle and advanced driver- assistance system (ADAS) technologies. One of the key aspects of this technology is the parking assist system. The core function of a parking assist system is to help drivers in parking their vehicles safely and efficiently. This paper proposes a method for low-cost real-time semi-autonomous vehicle parking in which a Vision-Based Parking Assist System (VPAS) gives the driver maneuver recommendations for reverse bay parking. The proposed method integrates wide-angle lens correction, bird-eye surround view, and user-guided vision-based parking line detection as ways to calculate recommendations for the driver. VPAS aims for affordability and generality, thus it emphasizes streamlining most of the calculations to compensate for realtime needs while maintaining reliability in a relatively low-cost system that can be run on an entry-level traditional hatchback car. To verify the performance of the proposed methods, experiments on the integrated system are conducted in a controlled environment. From experimental results, we demonstrate the performance of VPAS in terms of real-time and accuracy aspects while running on a 4-cores 3.5 GHz processor powered by the car battery.

Efficiency of photovoltaic can be optimal with power tracking system. Maximum Power Point Tracking (MPPT) is static tracking to harvest the electrical energy of photovoltaic module. Photovoltaic module can optimal generated energy in ideal condition that mean irradiation condition about 1000 W/m2 and temperature of 25ºC without shadow on surface of photovoltaic module. However, the implementation photovoltaic work in static and dynamic weather. Surface of photovoltaic module it is often blocked by a shadow like a tree, building, dust and any object around photovoltaic module. This problem resulted two or more peak power on P-V curve. This condition is called partial shading. Partial shading can’t be solved by using the conventional method therefore artificial intelligent method is needed. Hence, this paper comparison some method of MPPT that is Perturb and Observe, Fuzzy Logic Controller, and Flower Pollination Algorithm for normal and partial shading condition. MPPT using Zeta converter to control switching duty cycle. The performance of three methods is tested simulation by PSIM. Result from simulation show that the Fuzzy Logic Controller the best solution in normal condition with accuracy more than 99% and response to convergence. The other hand, Flower Pollination Algorithm method is the best solution for partial shading condition without oscillation and accuracy more than 98%.

In the last decade, Indonesia shifted from one of the cleanest countries in the world to one of the countries with high air pollution, especially in big cities like Jakarta, Surabaya, etc. This paper presents a preliminary study of the building of a smart sensor node system to monitor air quality for urban environments. Sampled air parameters were CO, CO2, and CH4. Incoming sensor data were classified using rules from the calculation of the entropy and information gain done before in the Decision Tree Algorithm rule finding steps. The classification is done on a Raspberry Pi device using conditional if-else on the programs. The if-else condition makes the program could achieve air quality results. The decision results in the form of warning alert or data reports packed on a Raspberry Pi device. By then using LoRa transceiver, a medium-range communication system, these results sent to a PC server. Reliability testing has been carried out starting from the sensors, algorithm processing capability, until the transmission process with Time Division Multiplexing technique. Data is sent alternately between one node to another. Based on the testing results, the CO sensor shows good performance at pollutant levels up to 300 ppm, so do the CO2 sensor at values up to 500 ppm, and the CH4 sensor at values up to 250 ppm. Test measurements have been carried out in outdoor environments for feasibility of the transmission system that has designed.

The declining petroleum production in Indonesia requires the alternative of renewable energy and be more ecofriendly, so it needs more flexible alternative energy. One of them is the energy gained from oxyhydrogen gas (Brown Gas). Oxyhydrogen gas can be obtained by breaking down the water molecule (H2O) with the help of electrical energy or commonly called an Electrolisys process. In this study, used oxyhydrogen dry cell generators type with 316L stainless steel electrode material consisting of 6 cells with the variation of the KOH catalysts 100, 120, 140, 160, and 180 grams per 1 liter aquadest. The characteristics of the oxyhydrogen generator performance testing are obtained, power consumption, oxyhydrogen gas production rate, and oxyhydrogen generator efficiency. From the results of studies that have been conducted, it is possible to know that increasing the concentration of KOH catalysts leads to increased power consumption. The highest electrical energy consumption is 26.1 Watt at the concentration of the KOH catalyst 180 gr/l and the lowest electrical energy consumption is 8.8 Watt at the concentration of the KOH Catalyst 100 gr/l. Then the rate of oxyhydrogen gas production is increasing with increasingly high concentrations of KOH catalysts. The highest oxyhydrogen gas production is 6.53x10-2liters/min at the concentration of the 180 gr/l KOH catalyst and the lowest oxyhydrogen gas production is 1.86x10-2 liters/min at the concentration of the KOH Catalyst 100 gr/L. So the highest oxyhydrogen generator efficiency is 59.44% at the 120 gr/l concentration of the KOH catalyst.
印尼石油产量的下降需要可再生能源的替代，更加环保，因此需要更灵活的替代能源。其中之一是从氢氧气体(棕色气体)中获得的能量。氢氧气体可以在电能的帮助下通过分解水分子(H2O)来获得，或者通常被称为电解过程。在本研究中，采用316L不锈钢电极材料的氢氧干电池发生器类型，由6个电池组成，每升水中KOH催化剂分别为100、120、140、160和180克。得到了氢氧发生器性能测试的特点、功耗、氢氧产气率和氢氧发生器效率。从已经进行的研究结果来看，可以知道KOH催化剂浓度的增加会导致功率消耗的增加。当KOH催化剂浓度为180 gr/l时，电耗最高为26.1瓦特，当KOH催化剂浓度为100 gr/l时，电耗最低为8.8瓦特。随着KOH催化剂浓度的增加，生成氢氧的速率也随之增加。当KOH催化剂浓度为180 g /l时，产氢量最高为6.53x10-2l /min;当KOH催化剂浓度为100 g /l时，产氢量最低为1.86x10-2 l /min。在KOH催化剂浓度为120 g /l时，氢氧发生器效率最高，为59.44%。
