Automation systems play a central role in modern industries. The presence of automation within industries holds significant importance in enhancing efficiency throughout production stages. The rapid development of automation technology aims to alleviate human tasks, monitor operational processes, and regulate system performance optimally. In addressing the challenges of complex material handling, automation solutions have been implemented through the utilization of conveyor systems and robotic arms. Conveyors serve as material transport mechanisms, although they possess specific effectiveness, they also encounter operational limitations. On the other hand, robots as automated systems can be controlled through microcontrollers and possess physical capabilities for specific tasks. Within this context, the research involves the design of electronic systems employing PLCs for conveyor control and Arduinos for robotic arm control. Through the integration of conveyors and robotic arms, this prototype development demonstrates significant potential in meeting the demands of industrial automation. Comprehensive test results concerning load lifting capabilities reveal that the robotic arm can efficiently handle loads with a maximum weight of 17 grams. However, factors such as the suboptimal nature of the robotic arm material and limitations in equipment size also contribute to these outcomes.

Pet welfare is a human right that belongs to the animal itself. However, this does not get enough attention from the public or pet owners. Judging from the owner's lack of knowledge of the pets they own and the lack of facilities that support the welfare of the pets themselves. Inefficient and ineffective feeding of cats will affect the animal's diet. Because irregular eating patterns can cause digestive disorders in cats. For this reason, an automatic mechanism is needed that can be used to help feed pets according to the right time and dose. So that this final project will design and build an Automatic Cat Feeding Tool with an Open and Close System Using a Dynamo, Servo, and Sensor Limit Switch which is composed of several connected programs and is based on Arduino Uno. With the existence of an automatic cat feeding device, it is hoped that it can overcome the problems faced by cat owners. Apart from that, it can also save costs, increase the time and energy efficiency of cat owners, and can create a sense of calm for cat owners when leaving their pets at home even without full supervision

PENGGUNAAN FLY ASH DAN BOTTOM ASH SEBAGAI CAMPURAN PEMBUATAN BATA RINGAN DENGAN MENGGUNAKAN PROSES CELLULAR LIGHTWEIGHT CONCRETE (CLC)

Bobby Asukmajaya R. R. — Mon, 30 Sep 2024 00:00:00 +0700

FABA (Fly Ash and Bottom Ash) is a residual waste from burning coal which is widely used by industry to produce heat energy, an example is the use of FABA in PLTU (Steam Power Plant). One of the oldest PLTUs in Indonesia, namely PLTU PJB UP Paiton, has been using coal for a long time, the utilization of FABA is still quite minimal due to problems from the government in using FABA due to its entry into Hazardous and Toxic Material (B3) waste, but in 2021 through Regulation Government Number 22 of 2021 concerning the implementation of environmental protection and management is established if FABA is no longer included in B3 waste.

The process of making lightweight bricks is divided into 2, namely AAC (Autoclaved Aerated Concrete) and CLC (Cellular Lightweight Concrete). because the process is relatively simple and does not require expensive special tools. In this study CLC was chosen because it seeks to improve the quality of small industrial materials, so that the products produced meet the standards set by the government.

One way to use FABA waste is to make CLC lightweight brick mixture, because FABA material is classified as having a lighter specific gravity compared to the main material for making CLC fine aggregate at this time, namely sand. In this research, the effect of mixing FABA materials will be examined by substituting sand and cement, to obtain a mixture that is in accordance with SNI 8640: 2018 concerning Specifications for Lightweight Bricks for Wall Pairs.

The results of the research show that the substitution of cement with fly ash produces a smaller dry specific gravity and an increase in strength in mixtures B and C, then the substitution of fine sand aggregate with bottom ash results in a reduction in the CLC specific gravity value, and the compressive strength increases in mixture E, F, G, and H. The CLC lightweight brick mixture that meets the individual and average compressive strength according to SNI 8640:2018 is mixture G.

Roads are a very important matter in the field of construction, Indonesia as a developing country that will enter into a developed country is trying to meet construction needs. Innovations related to the development of good road construction need to be implemented, so that road construction in Indonesia can run well and have results that are in accordance with the standards set in the Indonesian National Standard.
In the previous research using medical mask waste, the selected part was using the inside of the mask, namely polypropylene, the results obtained were satisfactory, but it was less effective in the field directly because the mask had to be sorted inside and outside, so that for further research it was made directly. the shredded mask waste is intact, so that the manufacturing process can be carried out directly without requiring time to sort out the existing waste.
The inside of a medical mask contains several polymers that are difficult to decompose, so there is a risk of contaminating the environment. Moreover, the need for masks during a pandemic is very much, and even now there is no specific way to use them optimally and safely. It is hoped that the use of medical mask waste as an asphalt mixture will increase the stability of the asphalt in the event of cracks due to the large load on the road.
The results of the research showed that the effect of adding mask waste was that there was the greatest increase in stability in the 5% mixture, and gradually decreased in the 10%, 15% and 20% mixture. Compared to the normal mixture (0%) the stability value increased by 70% in the 5% mask mixture. The effect of adding a mask mixture makes the flow value smaller, so that the asphalt has insufficient flexibility. The MQ or Marshall Quotient value is largest in the 15% mixture. A mixture of 10%, 15%, 20% does not meet the VIM values determined in the 2018 general construction specifications.
