Fuel and chemical cargo are essential tools for national security. There is the potential for fire and environmental pollution when occurring an accident such as a collision or overturning. On the other hand, cases of cargo theft are also reported frequently. Currently, preventive efforts are carried out by attaching warnings to the vehicle body with stickers, but it is a passive method. Therefore, this article presents a design and application for monitoring vehicles in real-time with Electronic Tracking Control Systems (ETCS). If the vehicle speed is more than 60 km/hour, ETCS will send an SMS to the vehicle owner about the speed and location of the vehicle being monitored. With ETCS, vehicle accidents and misuse can be minimized by quick monitoring and communication between the owner and the driver.

This article is the result of implementing the CSR program of PT PLN Magelang Regency branch to help solve problems in the Rahayu Manunggal Women Farmers Group (KWT). High production costs and low profits are obstacles faced by KWT Rahayu Manunggal. This problem is caused by the production process of making brown sugar which uses quite a lot of energy, including the drying process of brown sugar. Applying an energy-efficient oven at KWT Rahayu Manunggal can help overcome this problem. The concept of the oven machine is designed by utilizing the heat/energy stored in the exhaust gas produced by the sap cooking furnace. The results obtained from this system can increase profits and reduce production costs, as well as improve the cleanliness of brown sugar processing.

During this time, the AFR control systems on the Ligh Duty Vehicles (LDVs) generally only engage the engine condition, such as manifold pressure, engine speed. In fact, fuel consumption is not only influenced by the engine dynamics but also influenced by outside factors such as gear position (transmission) and vehicle speed. Therefore, this paper presents a simulation to control the Air to Fuel Ratio (AFR) on Electronic Fuel Injection (EFI) engine that accommodated engine dynamics, vehicle speed dynamics, and gear position dynamics (transmission). Fuzzy Logic Controller (FLC) was selected for AFR modeling because of the engine work in a non-linear condition. The simulation results show that the model developed is able to control the AFR on the vehicle speed changes. Even, the system is able to perform fuel cut-off at the time of deceleration from high speeds.

Appropriate diabetes mellitus (DM) wound care requires safe and comfortable space and facilities for patients and nurses. However, the existing hospital bed for DM has not supported the safety and comfort for nurses to serve patients, including the problem of liquid waste and some DM wounds emit a foul smell. Therefore, a hospital bed for DM wound care was designed in this research to support professional, efficient, ergonomic, and safe nursing practice. Multidisciplinary collaboration by engineers, wound nursing practitioners, and industry is carried out in this project. The level of risk of work disturbances was evaluated using a rapid entire body assessment (REBA), the level of risk of contamination was evaluated by a qualitative exposure assessment, and the level of comfort was measured using the visual analog method. Trials on 30 respondents consisting of 28 nurses and 2 doctors indicated that they were comfortable working with the new design of this prototype with lower risk.

Fuel Control Systems for Planetary Transmission Vehicles: A Contribution to the LPG-fueled Vehicles Community Suroto Munahar; Bagiyo Condro Purnomo; Hasan Köten

Publisher : Universitas Muhammadiyah Magelang

The bi-fuel system vehicle (gasoline/LPG) has been developed for a long time because it has the ability to switch fuels, both built as an original equipment manufacturer (OEM) or as a modified vehicle. However, on vehicles with planetary automatic transmissions, additional control systems are needed to produce optimal performance, both on gasoline and LPG operations, especially on uphill roads. Old vehicles with planetary automatic transmissions are not equipped with road slope angle sensors, so on uphill roads and the driver has not mastered road conditions, the engine tends to stop suddenly. Therefore, this study aims to develop a fuel control system (LPG operation) on a planetary automatic transmission to control gear shifts based on the level of the road slope. A simulation with MATLAB Simulink we used to create a control system, with objective function and constraint defined. As a result, the control system can recognize the level of the road slope to control the speed gear shift. This control system is promising and reliable to be implemented in real conditions.

The emergence of Corona Virus Disease 19 (Covid-19) required a new method to control its spread. During this time, controlling COVID-19 was carried out by implementation of a sterilization chamber using a liquid-based disinfectant. However, the use of liquid-based disinfectants has been evaluated to be less effective because it allows disrupting the respiratory tract. Therefore, this work presents a negative pressure sterilization chamber using Ozone and UV-C lamp. Ozone has been recommended by the Indonesian Institute of Sciences (LIPI) as a substitute for liquid-based disinfectants. In addition, to maximize performance, the chambers are added with UV-C lamps. The negative pressure sterilization chamber with Ozone and ultraviolet lamps was successfully created with the main parts of the cubicle chamber, an Ozone generator, at least one ultraviolet lamp, exhaust fan, switch, and a timer. The negative pressure sterilization chamber with Ozone and ultraviolet lamps according to this work, where the Ozone supply from the Ozone generator is made automatically to the door opening and closing. The duration of the Ozone supply was regulated by a timer. Then, the ultraviolet lamp can be activated together with Ozone or independently. With the implementation of this sterilization chamber, the spread of the Covid-19 virus is expected to be suppressed in a safer way than using liquid-based disinfectants.
