ABSTRAK Fly ash memiliki sifat pozzolan, dapat mengikat jika bereaksi dengan air. Proses peleburan biji nikel menghasilkan limbah berupa slag yang jumlahnya sangat besar. Bottom ash merupakan butiran material yang berada pada dasar tungku pada proses pembakaran batu bara untuk pembangkit listrik tenaga uap (PLTU) batu bara, bagian halus butiran terbang ke udara berupa fly ash. Tujuan yang hendak dicapai dari penelitian ini adalah untuk mengetahui karakteristik agregat limbah yaitu slag nikel dan bottom ash untuk bahan pembuatan beton dan mengetahui pengaruh fly ash type C sebagai bahan tambahan (additive) pada beton terhadap workability dan nilai kuat tekan beton. Hasil penelitian menunjukkan bahwa material limbah slag nikel dan bottom ash secara umum layak dan dapat digunakan sebagai bahan pembuatan beton, kecuali nilai serapan air bottom ash yang relatif tinggi yaitu 6,16 % melebihi batas serapan air yang dipersyaratkan yaitu maksimal 3%. Pemanfaatan fly ash type C sebagai bahan tambahan (additive) pada beton meningkatkan workability beton segar, nilai slump test semakin meningkat seiiring dengan penambahan persentase fly ash. Nilai kuat tekan beton meningkat seiring dengan penambahan persentase fly ash sebagai additive sampai kadar 30% dengan nilai kuat tekan 29,87 MPa, selanjutnya penambahan fly ash mengakibatkan kuat tekan beton menurun. ABSTRACT Fly ash has pozzolanic properties and has the ability to form chemical bonds with water. The process of smelting nickel ore produces a substantial amount of slag. Fly ash is the airborne residue of bottom ash, which settles at the bottom of the furnace during the combustion of coal in coal-fired steam power plants (PLTU). The objective of this study is to assess the characteristics of nickel slag and bottom ash when used in concrete, as well as to examine the impact of using type C fly ash as a concrete additive on both workability and compressive strength. The analysis determined that nickel slag and bottom ash waste can be employed in the production of concrete, despite the fact that the water absorption value of bottom ash, which stands at 6.16%, beyond the prescribed limit of 3%. Type C fly ash enhances the workability of fresh concrete and increases the value of the slump test. Fly ash initially increases the compressive strength of concrete by 30% to a value of 29.87 MPa, but subsequently reduces it.

Nurses are human resources who have an important role in medical installations, especially hospitals. Nurses have various tasks such as assisting doctors in examining, treating and serving patients, and other tasks such as administration. With these various tasks, physical and mental fatigue often occurs in nurses. To reduce the workload, robots have been used in hospitals around the world, especially in hospitals in Indonesia. This research aims to produce an initial concept for the exterior design of a nursing assistant robot using an ergonomics approach. The research methodology uses product design and development framework, especially in conceptual design process which start from customer needs identification to design iteration. From the research it can be concluded that determining robot dimensions is based on anthropometric standards, user posture, hardware size, and so on. The main consideration in determining the size of the robot is the reach of the hand to pick up and store items, the range of the eye to see the interactive display screen.

The use of electricity in the world continues to increase over time, the main source of producing electricity in the world is coal which is a basic material that takes a long time to form. Since 2021, British patrol has recorded that coal supplies in the world are available at 1,074,108 million tonnes. In Indonesia, coal still provides 60% of the country's electricity supply and the other 40% uses other energy such as water, steam, gas and other energy. New renewable energy development goals through the Sustainable Development Goals (SDG) in utilizing wind energy through vertical axis wind turbines. The research made three turbine models with different shapes, which then collected voltage data with an air compressor. The experimental results show that the average voltage generated by the two turbine models is 240 mV and 229 mV respectively. For the third model using two sampling methods obtained 353 mV and 292 mV. The use of vertical shaft wind turbines can be used in urban areas, especially in some tall buildings and parks. Research can still be developed by adding several other factors such as wind speed, turbine rotation speed and the aerodynamics of the turbine shape. and using a dc generator that requires a small torque so that it can increase the electric power produced.

Healthcare-associated infections or nosocomial infections are infections that are acquired after admission to a hospital. This type of infection extends the length of stay, increases the cost of healthcare, and increases the mortality rate. This infection is caused by pathogens that are present in the hospital environment. These pathogens are transmitted when a hospital worker comes in contact with a patient or their environment. Thus, it is important to reduce the contact between them to stop the spread of pathogens. To reduce contact an autonomous service robot is utilized to deliver food or medicine to patients. This robot will be able to go to multiple target positions autonomously and will be controlled by a web application. Furthermore, the robot can provide a video call if the patient needs help. The robot platform used is the turtlebot3 and the software framework used is robot operating system 2 humble. The inflation radius and cost scaling parameters are tuned to increase the navigation success rate. Problems encountered during testing include glass windows not being detected by lidar, noisy lidar data, and obstacles being too low to be detected. These problems are solved using tape, costmap and laser filter, and keepout zones respectively. To evaluate the performance and capability of the app the robot is tested using a set of target locations entered on the app. During testing poor odometry causes localization error that causes recovery behaviors. The final system has a navigation success of 95%, with an average navigation speed of 0.17 m/s, and an average distance to target of 0.0587 m.
