As we know, waste has a big influence on human life. And it cannot be denied: the use of waste, especially plastic waste, is a problem that we should be more aware of.
In fact, the production of plastic waste in Indonesia has increased very significantly. According to the Kementrian Lingkungan Hidup Dan Kehuatan Indonesia (KLHK), the contribution of plastic waste in Indonesia has increased since 2010. Especially in the Malang Regency area, the increase in waste produced during the holidays has come.
The factors above can occur because of our lack of awareness as humans to better understand and be concerned about the current condition of the earth. The need for education and awareness that starts with oneself to start disposing of trash in its place
Also, habits that are difficult to change, such as disposing of trash in the wrong place, even if it's a small thing, can have a big impact in the future. One of the visible impacts is the accumulation of garbage; when waste has accumulated, it will become a nest for germs and bacteria, which are the main causes of disease.

Indonesia contributes 64 million tons of plastic waste annually, second only to China. Many schools in the country still use ineffective manual waste sorting systems, and a majority of the population does not prioritize waste sorting due to confusion. This can lead to contamination of other waste when there is contaminated waste.

As we know today, there are more than 8 billion tons of plastic garbage in the world. Plastics include substances that are harmful to both the environment and living creatures. That where this is a very serious problem, given the age of the earth is getting older. A year is always a major problem, many factors that can cause one example is to throw away any rubbish. The habit of disposing of garbage is almost a bad habit and is considered normal, especially if the bad thing is seen by a child who is still underage. According to the source of parenting Co.id, the child is an imitator. At all times, your child’s eyes are always observing, his ears are whispering, and his mind is digesting whatever you do. They do not know what is bad and what is good, they are still in the learning phase. However, even though it has been said that polluting the environment is wrong, some of them still do it. Many of its factors start from them reasoning that they are lazy looking for the trash around him, they feel that it is a waste of time, even they are not interested just because they think it is very boring. If this continues to happen, then what is the fate of our planet? Considering “they” are the successors of the next generation? And the worst of all, is their bad habits being carried on until they grow up. How good it is that we as successors must defend and preserve our land. Who else if not we as young people who will take care of the earth.

We provide solutions by creating tools that can help with problems that make it difficult for someone to sort waste. The tool we created is called Ventrashine (Vending Trash Machine).
This prototype was made with a combination of audio bits as a basic tool for differentiating organic and non-organic waste, using a servo as a waste separator, a traffic light as a marker for the type of waste, and an LCD as information that is useful for educating people who make waste in Ventrashine.
This tool will work when someone creates trash, and the sound from the trash will be detected by the audio bit, and automatically the audio bit can sort the trash according to the trash that has been entered.
Our tool has the advantage of being useful for people who have difficulty distinguishing organic and non-organic waste. Besides that, our tool is useful for educating people about the importance of disposing of waste in its place and the types of waste.

Plastic pollution has and always will be a massive problem in our waters. Not only do our country produce a staggering 175 thousand tons of trash a day, occasionally, we just dump it into our rivers and oceans thus causes trash buildup in for example, rivers. It is causing many problems such as floods, horrible smell and bad environment. This has been a problem for the residence of Ciliwung. Especially the people that live near the river. Awareness around the people is still very low. We can increase awareness by having Seminars and speeches. however, it is not quite effective as people are still throwing junk at the river.

due to lack of awareness of the residents of Ciliwung river, we devised a way to clean the river for a moment until the residents realized what theyre doing is bad. We created a boat capable of cleaning Ciliwung river and other rivers like it. We call it the Garbage Destroyer 3000. A boat capable of picking up trash, sort it from big pieces and small pieces and compact it. The trash will be brought into a recycling facility and be recycled to make various products. The boat will be run on solar panels and therefore it does not emit carbon emissions. The boat will be very modular making it suitable for every rivers and even oceans.

Sortify is an automatic trash bin sorting system for schools that sorts different types of waste, such as organic, plastic, and metal, into separate bins using a user-friendly cencor. The system promotes sustainable waste management practices and educates students on proper waste disposal, creating a cleaner and healthier environment. Sortify enhances the overall learning experience and contributes to the well-being of the school community.

To solve this problem, we created a tool called Coresimu (Code Revulotion Simulator)
The initial design was a prototype of a combination of the shape of tubes and bars, bright colors, and there is an attractive decoration for children. This tool serves as a garbage barrel, but what makes this barrel different from the others is that this tool was created with the presence of technology in it. The one where the feature throws the garbage in an attractive way, just put the plastic on it and press the button then the rubbish will spin and be thrown underneath it. If someone throws 5 plastic garbage, then the gift box next to it can be opened, where for the children this is very interesting because they can get a gift for throwing the trash. Of course, this can educate that throwing the garbage in place is very important, and they get a reward for doing a good thing. The instrument is also equipped with cheerful music and melodies.  In addition, this tool has a quiz, if you press the code of the button correctly, then on the LED screen will appear a few questions, questions that are faced are also educational that can be understood by children. (seputar tentang perbedaan sampah anorganik dan organik).

If that was the initial design of the prototype, then the second design to refine the Prototype was to make the visualization design more attractive to children. We take the concept of the shape of a giraffe because some children love fabel cartoons (animals), bright yellow colors and young brown spots are a fitting combination and can easily attract the attention of children. We call this giraffe "Core", which has its own meaning.
The most important or central part of something good thing according to the Oxford Dictionary. The way the machine works does not change the previous design but without using moving, so immediately insert plastic garbage. For the gift box will contain a Tote bag painted cartoon, and for the layout design planned we shape into a bag of the exploring giraffe namely Core. Qiuzz is still there, but we plan to add more variations of questions. The plan is aimed at children and put this tool in several schools, Elementary School, and middle school. With this we want all young generations to understand the importance of protecting the environment for the survival of living creatures.

We find it difficult to find a longer cable, as well as what are the possibilities that could occur if our tool has been implemented in a real environment.
